Immunohistochemical localization of lutropin beta (LH beta) and follitropin beta (FSH beta) in the pituitary gland of the frog Rana japonica was studied by the peroxidase-anti-peroxidase method and the two-face, double-labeling method with different-sized gold particles at the light- and electron-microscopic levels, respectively, using monoclonal antibodies(More)
We investigated the laxative and anti-diarrheal activity of polycarbophil, an insoluble hydrophilic polymer, in comparison with other agents used for treating functional bowel disorder (FBD). In naive rats, polycarbophil (500 mg/kg) increased fecal weight and water contents without producing diarrhea. Carboxymethylcellulose (CMC) did not produce evident(More)
To estimate the effect of a new gastroprokinetic agent, N-[4-[2-(dimethylamino)ethoxy]benzyl]-3,4-dimethoxybenzamide hydrochloride (HSR-803), on non-ulcer dyspepsia, the influence of HSR-803 on gastrointestinal propulsion was assayed in dogs, rats and mice in comparison with some gastroprokinetic agents. HSR-803 (30 mg/kg, p.o.) significantly enhanced(More)
The pharmacological properties of 4'-ethyl-2-methyl-3-pyrrolidinopropiophenone hydrochloride (HSR-770), a new centrally acting muscle relaxant, were investigated in experimental animals. HSR-770, within a dose range of 1-10 mg/kg i.v., relaxed alpha- and gamma-rigidities in rats, the dose required to relax gamma-rigidity being lower than the dose required(More)
We investigated the effects of itopride hydrochloride (itopride, N-[4-[2-(dimethylamino)ethoxy]benzyl]-3,4-dimethoxybenzamide hydrochloride), a gastroprokinetic agent, on the colonic motor activity in vitro and in vivo, in comparison with benzamides, cisapride hydrate (cisapride), and mosapride citrate (mosapride). Itopride stimulated both peristaltic and(More)
The effects of HSR-902, an antimuscarinic agent, on development of various gastric and duodenal lesions, gastric secretion, pupil size and salivation in rats were compared with those of pirenzepine.2HC1 (pirenzepine, antiulcer agent) and timepidium bromide (timepidium, antispasmodic). 1) HSR-902 (10-100 mg/kg), given orally, dose-dependently inhibited the(More)
The effects of HSR-902, an antimuscarinic agent, on acute gastric mucosal lesions induced by various necrotizing agents, gastric mucus secretion and gastric HCO3- secretion in rats were compared with those of pirenzepine.2HCl (pirenzepine), an antiulcer agent. 1) HSR-902 (10-100 mg/kg), given orally, dose-dependently prevented the gastric mucosal lesions(More)
