Autoimmune gastrointestinal dysmotility (AGID) is a limited form of autoimmune autonomic neuropathy occurring idiopathically or in a paraneoplastic context. This disorder is considered rare, but is underrecognized as a cause for GI dysmotilities of varying anatomic extent, severity, and duration. We describe the diagnosis and management of an instructive case.

Concurrent exposure to pyridostigmine bromide (PB), permethrin (PERM) and/or N,N-diethyl-m-toluamide (DEET) may have contributed to the development of a syndrome that appears to have afflicted military personnel who served during the Gulf War. The present experiment sought to evaluate the behavioral effects of these compounds alone, or in various combinations, in male and female rats. Subjects were exposed to a multiple fixed-ratio (FR) 50, fixed-interval (FI) 2-min schedule of reinforcement. PB dose-dependently decreased FR and FI response rates. FR responding was disrupted by lower doses and there were no differences between the sexes. PERM vehicle administration decreased response rates maintained by both schedules of reinforcement; this was offset by an increase in response rate after the administration of the intermediate dose of PERM. The highest dose of PERM decreased both FR and FI response rates. FR rates in male rats were more disrupted than those in female rats. Only the highest dose of DEET decreased FR and FI response rates in male and female rats. FR rates were more disrupted in female rats than in male rats. Synergistic effects were only observed when FI response rates decreased in male rats upon exposure to half the low dose of PB with half the low dose of PERM or half the low dose of PB with half the low dose of DEET. The results of this experiment thus show that small doses of PB, PERM and DEET disrupt well-established, schedule-controlled behavior in male and female rats in a schedule- and gender-dependent manner; schedule-dependent and gender-dependent synergistic effects were also observed. The mechanism by which the compounds exert these behavioral effects remains to be determined.

Mean RE values at 15 minutes, when the maximum effect of pyridostigmine was anticipated, showed a statistically significant difference between groups (53.8 ± 10.5 in group P and 48.0 ± 8.8 in group C; P = 0.030). However, mean SE at 15 minutes showed no significant difference between the two groups (P = 0.066). At 15 minutes, there were significant differences in the TOF ratio between the two groups (P < 0.001).

The aim of this study was to investigate the mechanisms by which glucocorticoids inhibit GH secretion in man. In 10 normal volunteers subjects we compared the pattern of GHRH-induced GH release to that elicited by similar challenge given 60 min after a pretreatment with drugs affecting adrenergic and muscarinic cholinergic neurotransmission, both in basal situations and after having induced hypercortisolism. In a first study (P), synthetic GHRH [GRF-(1-29); 1 microgram/kg, i.v.] was administered 60 min after giving placebo. In other experiments, the administration of propranolol (PRO; 40 mg, orally), or clonidine (CLO; 0.300 mg, orally), or pyridostigmine (PD; 120 mg, orally) was followed by GHRH administration 60 min later. These experiments were repeated after giving a nocturnal dose of dexamethasone (DEX; 8 mg, orally at 2300 h). The administration of DEX significantly (P < 0.05) blunted the GH response to GHRH (peaks: 10.7 +/- 3.9 vs. 20.3 +/- 5.5 micrograms/L; DEX vs. P study, respectively). Conversely, either beta-adrenergic blockade (PRO), or alpha 2-adrenergic agonism (CLO), or the enhancement of muscarinic cholinergic tone (PD) significantly increased the GH response to GHRH (peaks: 43 +/- 4.6, 55.6 +/- 5.6 and 51.2 +/- 7, micrograms/L; PRO, CLO, and PD, respectively; P < 0.01 vs. P study). After nocturnal DEX administration, both PRO and CLO, but not PD, were able to reverse the inhibitory effect of DEX on GHRH-elicited GH release (peaks: 39 +/- 5.5, 25.9 +/- 3.9 and 12.9 +/- 3.1, micrograms/L; DEX + PRO, DEX + CLO, and DEX + PD, respectively). However, whereas the potentiating effect of PRO on GHRH-elicited GH release was still observed under hypercortisolism, it was lacking for both CLO and PD when these drugs were given in this situation. These data suggest that the inhibitory effect of glucocorticoid excess on GH release is due to increased hypothalamic somatostatin secretion which appears to be dependent on DEX-induced enhanced beta-adrenergic responsiveness. Moreover, the data further support a major role of hypothalamic alpha 2-adrenergic and beta-adrenergic activities in GH neuroregulation in man.

Aminostigmin, a novel reversible inhibitor of cholinesterase developed in Russia, has been tried in management of poisoning with cholinolytyics, antihistamine drugs, tricycle antidepressants and derivatives of 1,4-benzodiazepine. The treatment of 144 patients with aminostigmin and 20 patients with galantamin showed close to similar efficacy of these drugs. The scheme of aminostigmin administration is proposed warranting fast relief of cholinolytic syndrome in subjects poisoned with cholinolytics, antihistamine drugs and antidepressants. Benzodiazepines poisoning was unresponsive to aminostigmin. Rare side effects were caused by overdose. Aminostigmin is an effective antidote in cholinolytic poisoning.

Many factors have been considered as possible causes of the unexplained illness reported by veterans of the Gulf War (GW). In this study, we report an analysis of risk factors and unexplained illness in a population-based sample of GW veterans who underwent clinical evaluation. Multiple risk factors were compared in 241 veterans who met criteria for unexplained illness and 113 healthy controls. Results suggest that GW unexplained illness is most highly associated with combat conditions, heat stress, and having sought medical attention during the GW. When controlling for multiple simultaneous exposures during the GW, interactions around pyridostigmine bromide, insecticides and repellents, and stress were not significant. These results indicate that most unexplained illness in GW veterans cannot be explained by neurotoxic effects of exposures to chemicals that inhibit cholinesterase activity.

The protection afforded by TCP (thienylcylohexylpiperidine), a non-competitive blocker of N-methyl-D-aspartate (NMDA) receptors, against the seizures and lethality produced by 2 x LD50 of soman (62 micrograms/kg, sc), an irreversible inhibitor of cholinesterase, was studied in guinea-pigs. In the presence of additional anticholinergic medication (pyridostigmine: 0.2 mg/kg, sc, 30min prior to soman; atropine sulphate: 5mg/kg, im, 1 min post-soman), TCP pretreatment (2.5mg/kg, im, 30 or 15 min prior to soman) did not generally prevent the appearance of soman-induced status epilepticus but did arrest it after 30-40 min in 80% (TCP-30min) or 100% (TCP-15min) of the convulsing subjects. Moreover, in all subjects treated curatively, TCP was able to interrupt ongoing status epilepticus in approximately 20, 10 or 8 min when it was administered 5, 30 or 60min respectively after the onset of epileptiform tracings on EEG. All of these curatively administered animals survived and recovered remarkably well. On every criteria examined (latency-to-seizure arrest, 24hr-survival rate, clinical recovery), injection of 2.5mg/kg TCP after 90min of seizures appeared slightly less efficient compared to earlier curative administration. Therefore, our study (a) establishes that the previously reported capacity of MK-801 (dibenzocyclohepneimine) to counteract soman toxicity is not unique and could be extended to other non-competitive inhibitors of NMDA receptors; (b) shows that TCP could easily prevent and, above all, interrupt soman-induced seizures; furthermore, TCP appears the first compound ever tested on soman poisoning that still displays satisfactory anticonvulsant activity after such a long duration of initial status epilepticus (90min); therefore, TCP might be of special value for the delayed therapy for soman poisoning; (c) confirms that NMDA receptors are involved in the maintenance of seizures and play an important role in other processes implicated in the overall toxicity (including the lethal respiratory effects) of soman poisoning.

1. Pyridostigmine bromide was administered subcutaneously (0.4 mumoles/kg) in mice twice a day for 3 weeks. The activities of the predominant (G1, G4 and A12) molecular forms of acetylcholinesterase were determined in diaphragm, extensor digitorum longus (EDL) and soleus muscles. 2. After the treatment the G4 and A12 forms were reduced in diaphragm, but increased in EDL and soleus. One week later all forms were elevated in all three muscles. At 2 weeks the activity had returned to normal in diaphragm but not in EDL and soleus. 3. A single dose of pyridostigmine was administered in mice which had been pretreated for 3 weeks and left untreated for 2 weeks, and in control mice. 4. In the controls there was no significant effect on the enzyme activities in diaphragm up to 5 days, but there were decreases in EDL, and increases in soleus. In the pretreated group all three forms were increased in diaphragm, especially the A12 form. In soleus and EDL there was a prolonged decrease in all forms, although in the soleus the A12 activity remained above normal. 5. Repeated treatment with pyridostigmine caused delayed changes in functional acetylcholinesterase. Furthermore the treatment had altered the sensitivity of the muscles to the drug.

This experiment was designed to assess the effects of acute and repeated administration of pyridostigmine bromide (a carbamate with prophylactic and therapeutic uses) on response acquisition. Experimentally naïve, male Sprague-Dawley rats were exposed to a situation in which lever presses were either immediately followed by food-pellet presentation or after a 16-s resetting delay. Different groups of rats received either one acute administration of pyridostigmine bromide (10 mg/kg, by gavage) or repeated pyridostigmine administration for 7 days (1.5 mg/kg/day, by gavage). Other groups were treated with distilled water for the same period of time. Both acute and repeated pyridostigmine bromide administration decreased serum cholinesterase levels by approximately 50%, but neither treatment affected brain cholinesterase levels in our assay. Acute and repeated drug administration produced the same behavioral effects. Subjects exposed to the 0-s delay conditions obtained many more food pellets than those exposed to the 16-s delay conditions. Administration of pyridostigmine bromide delayed the onset of responding in some, but not all, of the subjects in the treated groups, independent of the delay condition to which they were exposed. Many more responses were observed on an inoperative lever during the 16-s delay conditions than during the 0-s delay conditions, especially during the 16-s delay condition in which subjects had received acute vehicle administration. Whether or not these effects of small doses of pyridostigmine bromide on response acquisition are of central or peripheral origin will need to be determined in future studies, as response acquisition in the present experiment may have been affected by pyridostigmine's effects on gastrointestinal functioning and/or motor activity.

Following their return from deployment, Gulf War (GW) veterans reported widespread joint and muscle pain at rates that far exceeded those of soldiers returning from other conflicts. It is widely believed that exposure to insecticides, repellants and nerve gas prophylactics contributed to the symptoms of Gulf War Illness (GWI), but an animal model of GW pain has been elusive. In our previous work, we observed that 4-8 weeks exposure to pyridostigmine bromide (PB), permethrin and chlorpyrifos could produce persistent alterations in the physiology of Nav1.9 and Kv7 expressed in deep tissue nociceptors of the dorsal root ganglion. However, behavioral assessments from these same rats were not consistent with a delayed pain syndrome similar to that of GWI pain. In the present studies, we intensified the exposure to anticholinesterases PB and chlorpyrifos while retaining the same dosages. Animals receiving the intensified protocol for 30 days exhibited significant increases in resting for about 8 weeks after exposure. Thereafter, all measures were comparable to controls. Animals treated with intensified anticholinesterases for 60 days exhibited increased resting and reduced movement 12 weeks post-exposure. In whole cell patch studies, muscle and vascular nociceptor KDR and Kv7 ion channels exhibited increased amplitude relative to controls (e.g., normalized current and/or peak conductance) at 8 weeks post-exposures; however, at 12 weeks post-exposure, the amplitude of these currents was significantly decreased in muscle nociceptors. In current clamp studies, muscle nociceptors also manifested increased action potential duration, afterhyperpolarization and increased discharge to muscarinic agonists 12 weeks post-exposure. The decline in activity of muscle nociceptor KDR and Kv7 channel proteins was consistent with increased nociceptor excitability and a delayed myalgia in rats exposed to GW chemicals.

Pretreatment with 0.015 mg/kg VEC compared to 2 mg alcuronium led to a more pronounced decline in T1% and TOF-ratio (P less than 0.001). The time interval between injection of the intubation dose and complete relaxation (T1% less than or equal to 5%) was shorter in group Suc- than in VEC-pat. (P less than 0.001). Suc provides better intubation conditions than VEC (P less than 0.05). Recovery from muscle relaxation was faster in Suc- than in VEC-pat. (P less than 0.001). During Suc infusion in 8 patients a phase-II block (TOF ratio less than or equal to 30%) was observed.

There was only a modest non-significant increase in supine blood pressure and PRI. In contrast, acetylcholinesterase inhibition significantly increased orthostatic blood pressure and PRI and reduced the fall in blood pressure during head up tilt. Orthostatic heart rate was reduced after the treatment. The improvement in orthostatic blood pressure was associated with a significant improvement in orthostatic symptoms.

Pyridostigmine bromide (PB) is a reversible cholinesterase inhibitor used for treatment of myasthenia gravis and for prophylactic protection against organophosphate nerve agent. We previously showed PB can induce apoptotic death in rat brain following systemic treatment. To study mechanisms by which PB induces brain cell death, cultured rat cerebellar granule cells were used. Cytotoxicity was determined after exposure to PB (10-1000 microM) for 24 h; a high concentration of PB (>500 microM) significantly increased lactate dehydrogenase release, which was reduced by pretreatment with the antioxidant, N-t-butyl-alpha-phenyl-nitrone (PBN). Apoptosis, as determined by TUNEL staining, was concentration dependent (10-250 microM) after a 24-h exposure and cytotoxicity was confirmed by gel electrophoresis of DNA, release of cytochrome c from mitochondria, elevation of caspase activity, and electron microscopy. The oxidant-sensitive fluorescent dye 2',7'-dichlorofluorescin diacetate was used to detect reactive oxidative species (ROS) generation. Pretreatment with PBN, superoxide dismutase, catalase, or the nitric oxide synthase inhibitor N(G)-nitro-L-arginine methyl ester (L-NAME) blocked PB-induced ROS generation and apoptotic cell death. Pretreatment with atropine or MK-801 blocked ROS generation and the subsequent neurotoxicity, showing that both muscarinic and NMDA receptors mediate the response. DNA extracted from PB-treated cells revealed oligonucleosomal fragmentation on gel electrophoresis and antioxidants attenuated the DNA fragmentation, providing further evidence for a link of ROS generation and apoptosis. These results indicate that muscarinic receptor-mediated ROS generation is an initiating factor in PB-induced apoptotic cell death and activation of the NMDA glutamate receptor is directly linked to the response.

The aim of this study was to design and optimize a prolonged release matrix formulation of pyridostigmine bromide, an effective drug in myasthenia gravis and poisoning with nerve gas, using hydrophilic - hydrophobic polymers via D-optimal experimental design. HPMC and carnauba wax as retarding agents as well as tricalcium phosphate were used in matrix formulation and considered as independent variables. Tablets were prepared by wet granulation technique and the percentage of drug released at 1 (Y(1)), 4 (Y(2)) and 8 (Y(3)) hours were considered as dependent variables (responses) in this investigation. These experimental responses were best fitted for the cubic, cubic and linear models, respectively. The optimal formulation obtained in this study, consisted of 12. buy mestinon 8 % HPMC, 24.4 % carnauba wax and 26.7 % tricalcium phosphate, had a suitable prolonged release behavior followed by Higuchi model in which observed and predicted values were very close.

Accelerated stability studies confirmed that the optimized formulation remains unchanged after exposing in stability conditions for six months.

The effect of pyridostigmine on neuromuscular block produced by soman was studied in the isolated phrenic nerve-diaphragm preparation. In the rat, soman produced an irreversible reduction in tetanic tension and functional acetylcholinesterase (AChE) activity. Pretreatment with pyridostigmine before exposure of the diaphragm to soman, followed by removal of the anticholinesterase from the organ bath, produced a return of tetanic tension and an increase of 5% in functional AChE activity. Similar results were obtained in the guinea-pig. The changes in buy mestinon synaptic AChE activity were verified pharmacologically by showing a decrease in the blocking activity of acetylcholine in preparations pretreated with pyridostigmine in comparison to those given soman alone following removal of the anti-cholinesterase. The blocking dose of carbachol did not change in these two groups indicating that desensitization was not a component of the protective action. A comparison was also made of the results obtained by measuring inhibition of AChE in situ with those obtained from muscle homogenates. The implications of these results are discussed.

These data confirm that subjects with IDDM have reduced serum IGF-I and IGFBP-3 and increased IGFBP-1 levels, the latter being directly related to the fasting plasma glucose concentrations. The absence of any relation between changes in the IGF-I system and altered GH neuroregulation after cholinergic modulation suggests that changes in IGF-I are not the sole contributors to the altered buy mestinon GH neuroregulation which occurs in IDDM. We have also shown an acute stimulatory effect of pirenzepine on serum IGF-I and IGFBP-3 in normal subjects which is not present in IDDM although the underlying mechanisms is unknown.

The aim of this study was to verify that the stimulatory effect of cholinergic agonists on both basal and stimulated GH release observed in the morning persists in the night. The effects of pyridostigmine (120 mg orally), a cholinesterase inhibitor, on both basal and GHRH (1 micrograms/kg iv)-induced GH secretion were studied in 8 healthy volunteers, aged 22-30 years. In the morning, administration of pyridostigmine induced a significant increase in basal GH levels compared with saline (area under the response curve, mean +/- SEM: 277.0 +/- 54.0 vs 49.7 +/- 8.2 micrograms.l-1.h-1, p less than 0.02) as well as a strong potentiation of the GHRH-induced GH release (2117.6 +/- 353.0 vs buy mestinon 427.9 +/- 87.0 micrograms.l-h-1, p less than 0.02). In the night, GH secretion after pyridostigmine did not differ from saline (194.5 +/- 21.9 vs 89.4 +/- 28.7 micrograms.l-1.h-1). Moreover pyridostigmine failed to potentiate the GHRH-induced GH increase (1071.9 +/- 170.4 vs 740.2 +/- 150.9 micrograms.l-1.h-1). The pyridostigmine + GHRH-induced GH rise during the night was lower (p less than 0.05) than in the morning. All together, these data seem to indicate that cholinergic neurons controlling GH secretion are already maximally stimulated at night. As cholinergic activity negatively modulates SRIH secretion, our findings suggest that a reduced somatostatinergic tone in the hypothalamus is present during the night.

Gulf War Illness (GWI) is a multi-symptom disorder with features characteristic of persistent sickness behavior. Among conditions encountered in the Gulf War (GW) theater were physiological stressors (e.g., heat/cold/physical activity/sleep deprivation), prophylactic treatment with the reversible AChE inhibitor, pyridostigmine bromide (PB), the insect repellent, N,N-diethyl-meta-toluamide (DEET), and potentially the nerve agent, sarin. Prior exposure to the anti-inflammatory glucocorticoid, corticosterone Claritin Mg Dose (CORT), at levels associated with high physiological stress, can paradoxically prime the CNS to produce a robust proinflammatory response to neurotoxicants and systemic inflammation; such neuroinflammatory effects can be associated with sickness behavior. Here, we examined whether CORT primed the CNS to mount neuroinflammatory responses to GW exposures as a potential model of GWI. Male C57BL/6 mice were treated with chronic (14 days) PB/ DEET, subchronic (7-14 days) CORT, and acute exposure (day 15) to diisopropyl fluorophosphate (DFP), a sarin surrogate and irreversible AChE inhibitor. DFP alone caused marked brain-wide neuroinflammation assessed by qPCR of tumor necrosis factor-α, IL6, chemokine (C-C motif) ligand 2, IL-1β, leukemia inhibitory factor, and oncostatin M. Pre-treatment with high physiological levels of CORT greatly augmented (up to 300-fold) the neuroinflammatory responses to DFP. Anti-inflammatory pre-treatment with minocycline suppressed many proinflammatory responses to CORT+DFP. Our findings are suggestive of a possible critical, yet unrecognized interaction between the stressor/environment of the GW theater and agent exposure(s) unique to this war. Such exposures may in fact prime the CNS to amplify future neuroinflammatory responses to pathogens, injury, or toxicity. Such occurrences could potentially result in the prolonged episodes of sickness behavior observed in GWI. Gulf War (GW) veterans were exposed to stressors, prophylactic medicines and, potentially, nerve agents in theater. Subsequent development of GW Illness, a persistent multi-symptom disorder with features characteristic of sickness behavior, may be caused by priming of the CNS resulting in exaggerated neuroinflammatory responses to pathogens/insults. Nerve agent, diisopropyl fluorophosphate (DFP), produced a neuroinflammatory response that was exacerbated by pre-treatment with levels of corticosterone simulating heightened stressor conditions. While prophylactic treatments reduced DFP-induced neuroinflammation, this effect was negated when those treatments were combined with corticosterone.

Recently, the FDA approved the medical use of oral pyridostigmine as prophylactic treatment of possible nerve agent exposure: the concept is to block the cholinesterase transitorily using the carbamate (pyridostigmine) in order to deny access to the active site of the enzyme to the irreversible inhibitor (nerve agent) on subsequent exposure. We have shown previously that tiapride is in vitro a weak inhibitor of acetylcholinesterase and that in rats administration of tiapride before the organophosphate paraoxon significantly decreases mortality. The purpose of the present study was to compare tiapride- and pyridostigmine-based pretreatment strategies, either alone or in combination with pralidoxime reactivation, by using a prospective, non-blinded study in a rat model of acute high-dose paraoxon exposure. Groups 1-6 received 1 microMol paraoxon (approximately LD75) groups 2-6 received in addition: G(2)50 microMol tiapride 30 min before paraoxonG(3)50 microMol tiapride 30 min before paraoxon and 50 microMol pralidoxime 1 min after paraoxon G41 microMol pyridostigmine 30 min before paraoxon G(5)1 microMol pyridostigmine 30 min before paraoxon and 50 microMol pralidoxime 1 min after paraoxon G(6)50 microMol pralidoxime 1 min after paraoxon. Mortality data were compared using Kaplan-Meier plots and logrank tests. Mortality is statistically significantly influenced by all treatment strategies. Tiapride pretreatment followed by pralidoxime treatment (G3) is aux par with pyridostigmine pretreatment followed by pralidoxime treatment (G5). Tiapride pretreatment only (G2) is inferior to pyridostigmine pretreatment only (G4). The best results are achieved Valor Ilosone Gel with pyridostigmine pretreatment only or pralidoxime treatment only (G4 and G6).

This study was undertaken to assess differences between young and elderly patients with respect to the duration of antagonism of metocurine neuromuscular blockade by neostigmine (NEO) or pyridostigmine (PYR). Patients were given either NEO (seven elderly and ten young) or PYR (seven elderly and eight young) and received nitrous oxide in oxygen (60:40) and 1 MAC halothane. Neuromuscular transmission was assessed by using evoked compound electromyography. Metocurine 0.1 mg/kg was given, followed by a continuous infusion to achieve 90% reduction in baseline single twitch height. After at least 30 minutes, either NEO (0.07 mg/kg) or PYR (0.14 mg/kg) and atropine (0.02 mg/kg) were given IV. After injection of NEO or PYR, the duration of maximal response (DOMR) was recorded. Mean (+/- SE) ages were 38 +/- 5 and Biaxin Usual Dosage 68 +/- 2 years in the two groups of patients receiving PYR. In the elderly, PYR significantly prolonged DOMR compared to younger patients (35.3 +/- 8.2 vs 14.4 +/- 4.2 minutes, respectively). The mean ages in the two groups of patients receiving NEO were 41.5 +/- 4 and 72 +/- 2 years. The elderly group demonstrated a significant increase in the DOMR compared to younger patients (32 +/- 10 vs 11 +/- 2 minutes, respectively). It is concluded that, compared to younger patients, the duration of action of NEO and PYR in the aged patient is prolonged.

Eight healthy adults were tested seven times, once with placebo throughout the examination and six times with the PD-GHRH test following no glucocorticoid pretreatment, pretreatment with hydrocortisone (HC) (30 mg/day and 80 mg/day for 1 and 3 days) or pretreatment with 15 mg prednisolone for 1 day. HC (80 mg/day for 1 day) in combination with PD significantly stimulated GH-levels compared to PD alone, 18.9 mU/ Micronase Cost l +/- 6.1 vs 3.0 mU/l +/- 0.8 (P < 0.05). However, peak GH-responses to PD in combination with GHRH were reduced during HC (80 mg/day for 1 day) compared to no glucocorticoid pretreatment in all healthy adults. Conventional HC therapy (30 mg/day for 1 and 3 days) did not significantly affect peak GH-responses.

Before any therapeutic intervention, an impaired GH response to PD/GHRH was noted in all patients. Restoration of GH response at 6 Buspar Good Reviews months was observed in six patients (50%); at 12 months in two; at 18 months in one patient. Two of the patients with no restoration of GH response at 12 months did not accept further investigation. Only one patient did not achieve an adequate GH response even when tested 30 months following cure of CS. Restoration of GH reserve was more commonly observed in those patients in whom there was recovery of the HPA axis. There was a good correlation between peak GH levels to PD + GHRH and ITT. No statistically significant difference was revealed in IGF-I levels between pre- and post-treatment evaluation.

Outer hair cells (OHCs) are the source of otoacoustic emissions, following a tropomyosin-miosin-dependent contraction, which are regulated by the olivocochlear bundle via the release of acetylcholine (ACh). ACh acts on ACh receptors (AChR) located on the OHC post-synaptic membrane. In myasthenia gravis (M.G.) neuromuscular Viagra Generic Online transmission is reduced due to the action of AChR autoantibodies. It has previously been shown that M.G. induces a reduction in transient evoked otoacoustic emissions (TEOAEs), which is reversed after administration of a cholinesterase (AChE) inhibitor. Distortion product otoacoustic emissions (DPOAEs) were recorded before and 60 min after oral administration of 60 mg pyridostigmine bromide in 25 patients with normal hearing affected by M.G. The results were compared with those from 25 age-matched normal controls. Mean values of DPOAE amplitude in myasthenic patients were significantly (p < 0.05) lower at all frequencies before drug administration. All patients showed an overall significant (p < 0.05) increase in DPOAE amplitude after drug administration, although without reaching the control values. Such a recovery was more evident and highly significant (p < 0.01) for middle and high frequencies and could be explained by a higher concentration of ACh receptors in the basal and middle cochlear turns. These data seem to confirm the role of ACh in the neurotransmission of the auditory efferent system and may represent a new in vivo model for the investigation of the physiology of this system.

To investigate the mechanism underlying the GH-releasing effect of arginine (ARG), we studied the interactions of ARG (0.5 g/kg infused i.v. over 30 min) with GHRH (1 microgram/kg i.v.) and with pyridostigmine (PD, 60 mg orally) on GH secretion in 15 children and adolescents with familial short stature (5.1-15.4 years). In a group of eight subjects ARG induced a GH increase not statistically different to that observed after GHRH (peak, mean +/- SEM: 38.0 +/- 10.4 vs 64.0 +/- 14.4 mU/l). The combined administration of ARG and GHRH led to GH levels (101 +/- 15.2 mU/l) higher than those observed after GHRH (P less than 0.025) or ARG alone (P less than 0.001) and overlapping with those recorded after combined PD and GHRH administration (111 +/- 22.4 mU/l). In the other seven subjects, ARG and PD administration induced a similar GH response either when administered alone (25.2 +/- 13.6 and 27.8 +/- 4.0 mU/l, respectively) or in combination (33.8 +/- 5.4 mU/l). In conclusion, our results show that in children ARG administration potentiates GHRH- but not PD-induced GH increase. These findings agree with the hypothesis that the GH-releasing effect of both ARG and PD is mediated via the same mechanism, namely, by suppression of endogeneous somatostatin release. Combined administration of either ARG or PD with GHRH has a similar striking GH-releasing effect which is clearly higher than that of GHRH alone.
