1. Tratamento clínico da fissura anal crônica. Estudo comparativo entre diltiazem 2% e betanecol 0,1% / Clinical treatment of chronic anal fissure. Comparision between diltiazem 2% and bethanechol 0,1%
A busca por uma terapia não-cirúrgica para o tratamento da fissura anal crônica resulta de que a esfincterotomia, a despeito de eficaz para a cura da fissura anal, pode levar a graus variáveis de incontinência fecal. Poucos estudos comparativos contemplando o emprego de bloqueadores de canais de cálcio podem ser identificados. Associadamente, a evidên

2. Modulation of urethral alpha-sympathetic by parasympathetic before and following bethanechol chloride injection
INTRODUCTION AND OBJECTIVES: Chagas' disease causes specific parasympathetic denervation and in its digestive clinic form promotes also functional alterations in bladder. Thus, the aim was to investigate the existence of balance between sympathetic and parasympathetic systems in lower urinary tract, as occurs in other organs. We verified the urethral closing

3. Direct muscarinic cholinergic inhibition of hepatic glucose production in humans.
To explore the potential role of the parasympathetic nervous system in human glucoregulatory physiology, responses to the muscarinic cholinergic agonist bethanechol (5.0 mg s.c.) and antagonist atropine (1.0 mg i.v.) were measured in normal humans. There were no changes in the plasma glucose concentration or rates of glucose production or utilization followi

4. Bethanechol decreases reaction time in senile dementia of the Alzheimer type.
Bethanechol, a muscarinic cholinergic agonist, was injected subcutaneously in eight cases of senile dementia of the Alzheimer type. Simple reaction time was measured before, 15 min and 30 min following the injection. Before injection, the patients had significantly longer reaction time than non-demented controls. A significant shortening of the reaction time

5. Role of cyclic adenosine monophosphate in amylase release from dissociated rat pancreatic acini
1. The effect of octapeptide of cholecystokinin-pancreozymin (CCK8), bethanechol, cholera toxin, glucagon and vasoactive intestinal polypeptide (VIP) on amylase secretion and lactic dehydrogenase (LDH) release from isolated rat pancreatic acini was studied.

6. Secretion of type II phospholipase A2 and cryptdin by rat small intestinal Paneth cells.
We examined the secretion of antimicrobial proteins and peptides into surgically isolated and continuously perfused segments of rat small intestine. Up to nine discrete antimicrobial molecules appeared in the intestinal perfusates following intravenous administration of bethanechol, a cholinergic agonist, or intralumenal instillation of lipopolysaccharide (L

7. Peptidergic and muscarinic excitation at amphibian sympathetic synapses.
A single-electrode voltage clamp was used to study the slow muscarinic and late slow peptidergic excitatory post-synaptic currents (e.p.s.c.s) in B cells of the paravertebral sympathetic ganglia of the bull-frog. Conductance decreases were measured during peptidergic e.p.s.c.s in nearly all cells at clamped potentials near the resting level. In about half of

8. Enterogastrone-like effect of peptide YY is vagally mediated in the dog.
Intraluminal fat inhibits gastric secretion through as yet undetermined mechanisms which involve release of one or more hormonal enterogastrones. As intraluminal fat releases Peptide YY (PYY) in amounts sufficient to inhibit meal-stimulated acid secretion, this ileo-colonic peptide exhibits the characteristics required of an enterogastrone. The present study

9. A comparison of the effects of sympathomimetic agents on gastric acid secretion by the rat stomach in vivo and in vitro.
1. The action of isoprenaline on gastric acid secretion in rats with Heidenhain pouches has been compared with its action in a rat isolated stomach preparation. 2. Isoprenaline (40 micrograms kg-1 h-1) inhibited the acid secretion in response to pentagastrin (20 micrograms kg-1 h-1) in conscious rate with Heidenhain pouches. 3. This inhibition could be aboli

10. Characteristics of phasic and tonic sympathetic ganglion cells of the guinea-pig.
Intracellular recording techniques have been used to determine the electrophysiological properties of sympathetic neurones in ganglia of the caudal lumbar sympathetic chain (l.s.c.) and in the distal lobes of inferior mesenteric ganglia (i.m.g.) isolated from guinea-pigs. Passage of suprathreshold depolarizing current initiated transient bursts of action pot

11. Secretory and radioligand binding studies on muscarinic receptors in bovine and feline chromaffin cells.
1. Muscarinic agonists enhanced catecholamine release from perfused cat adrenal glands with the following relative order of potencies: methacholine greater than oxotremorine greater than McN-A-343 greater than pilocarpine greater than bethanechol greater than muscarine. Because a continuous online electrochemical detection system was used to monitor catechol

12. Role of Muscarinic Cholinergic Receptors in Regulation of Guanosine 3′:5′-Cyclic Monophosphate Content in Mammalian Brain, Heart Muscle, and Intestinal Smooth Muscle
Effects of acetylcholine and of agents that mimic or block its physiological actions have been studied upon concentrations of guanosine 3′:5′-cyclic monophosphate (cyclic GMP) and adenosine 3′:5′-cyclic monophosphate (cyclic AMP) in slices of mammalian cerebral cortex, heart ventricle, and ileum. Acetylcholine, and cholinomimetic agents with a predom
