Uterine secretory cells receive a sympathetic cholinergic secremotor innervation. Nitric oxide (NO) has been suggested to be a second messenger of neurogenic modulated glandular secretion of the seminal vesicle. Thus a similar pattern for nervous ind

Intestinal fluid secretion, mainly derived from the crypts, induced, for example, by cholera toxin, decreases the passive transport of small hydrophilic molecules into the lumen. However, the effect of the fluid secretion on the passive absorption of

We demonstrated previously that hydrochloric acid secreted from the gastric glands traverses the mucus layer in channels above the gland openings. The driving force for creation of these channels is most probably the hydrostatic pressure generated in

In the gall bladder of a fasting subject, a decline in the pH of the contents occurs due to secretion of H+ from the mucosa. In this study in anaesthetized cats, the gall bladder lumen was perfused with a bicarbonate buffer bubbled with 4% CO2 in air

Basal alkaline secretion of the denervated rat ileum was monitored by a pH-stat method. Changes of transepithelial electrical potential difference (PD) were also continuously registered. In other experiments net fluid transport was measured with a gr

Ionized calcium (Ca 2+ ) and bicarbonate (HCO 3 - ) are important ions for gallstone formation. In the present study the effect of indomethacin and vasoactive intestinal peptide-antiserum (VIP antiserum) on the Ca 2+ , HCO 3 - and fluid secretion in

To characterize the intracellular mechanisms by which somatostatin modulates the insulin secretion, studies were performed with isolated rat pancreatic islets at 12 mmol l-1 glucose. Somatostatin (0.1-1000 nmol l-1) inhibited the glucose-induced insu

The electrolyte transport was compared in proximal and distal segments of the rat colon under control conditions and after induction of secretion on the CAMP-, the cGMP- and the Ca2+-pathway. Baseline short-circuit current was decreased by indometaci

Acid exposure of the duodenal mucosa is a well-known stimulant of the mucosal alkaline secretion. We have previously reported that a minor blood loss inhibits this secretory increment via activation of the splanchnic nerves. In the present study the
