This paper describes the morphology and distribution of the enteric nervous system (ENS) cells and fibres immunoreactive for choline acetyltransferase (ChAT), neuronal nitric oxide synthase (nNOS), substance P (SP), calcitonin gene-related peptide (CGRP), NF200kDa (NF200), and S100 protein. The percentages of subclasses of enteric neurons in the total(More)
REASON FOR PERFORMING STUDY In horses, morpho-functional studies related to the enteric nervous system (ENS) controlling the sphincters are lacking. OBJECTIVES To investigate immunohistochemically the morphology, distribution, density, phenotypes and projections of neurons controlling the ileocaecal junction (ICJ). METHODS Two young horses were(More)
Cycle control and tolerability of two monophasic oral contraceptive pills containing 30 microg ethinyl estradiol (EE) with either 150 microg desogestrel (DSG) or 75 microg gestodene (GSD) were compared in women starting oral contraception. A minimum of 200 healthy women at risk for pregnancy were to be treated for a total of 6 cycles per patient in a(More)
Since the sexual dimorphism of gastroduodenal ulcers is well known and might possibly relate to the actions of sex hormones, we studied the role of the female sex steroids, progesterone and 17beta-estradiol in cysteamine-induced mucosal ulcers in female Wistar rats (200-220 g). Administration of cysteamine (400 mg/kg, s.c.) provoked macroscopic(More)
The sexual dimorphism of gastroduodenal ulceration is suggested on the basis of clinical and experimental observations. This difference probably relates to the actions of endogenous sexual steroids. In the present study, the role of testosterone was evaluated in the generation of gastroduodenal mucosal injury provoked by cysteamine (400 mg/kg, s.c.). We(More)
It is known that cysteamine's ulcerogenic effect depends, among others, on a depletion of somatostatin (SRIH). Since growth hormone (GH) affects the release of hypothalamic SRIH, we have studied the influence of GH and the GH-SRIH interaction on the severity of gastric mucosa lesions induced by cysteamine. Female rats of the Sprague-Dawley strain were(More)
Forty eight women with atrophic endometrium were treated with estriol, 1 mg twice daily, by mouth for a minimum of 10 days and a maximum of 25 days. Vaginal hysterectomy was then performed and specimens were examined histologically. Results showed that estriol produces endometrial hyperplasia in 70.8% of the examined women; only 29.2% of the patients(More)
After mating with a sexually active male, groupsof female Sprague-Dawley rats were injected withcysteamine (400 mg/kg, subcutaneously) at day 0(controls), day 5 (early-stage pregnancy), and day 18(late-stage pregnancy) of pregnancy. In contrast tolate-stage pregnancy rats, early-stage pregnancy animalsshowed a decrease of cysteamine-induced(More)
It is known that cysteamine ulcerogenic effect depends, among others, on a depletion of somatostatin in the gastro-intestinal tract. Since growth hormone (GH) causes the release of hypothalamic somatostatin (SRIH) and potentiates the ulcerogenic action of cysteamine we have studied the influence of GH on gastro-duodenal mucosa levels of SRIH, and its(More)
Acid soluble biopolymeric substances (SBP) were isolated from different urban biowastes comprised of a range of materials available from metropolitan areas. These biowastes provided products with a chemical nature and solubility properties changing over a wide range and, thus, allowed to assess the effect of the variability of the chemical nature on(More)
