To find out whether a negative shift in subject's mood alters cardio-respiratory and endocrine responses to exercise, 20 young men performed a graded bicycle ergometer test (50, 100, 150 W): 1) when they experienced a mixed emotional and co...
Histaminergic components in carbachol-induced pituitary-adrenocortical activity [0.03%]

J Bugajski et al.
The involvement of central histaminergic mechanisms in stimulation of the hypothalamic-pituitary-adrenal (HPA) axis by carbachol, a muscarinic cholinergic agonist, was investigated in conscious rats. The HPA activity was assessed indirectly...

Using a nasopharyngeal and a neck electrode slow potentials synchronous with respiration were registered. Similar potentials were recorded in a patient with apnoea due to widespread paralysis of the Landry type. The potentials are thought t...

The experiment was aimed to further elucidate the phenomenon of sleep suppression observed earlier after electrolytic lesions of the lateral hypothalamus (LH). In male Wister rats the amounts of waking (W), slow wave sleep (SWS) and paradox...
Influence of SIN-1 and sodium nitroprusside (NANP) on ox-LDL metabolism in macrophages [0.03%]

I Wybrańska et al.
Effects of NO-donors (3-morpholinosydnonimine-SIN-1 and sodium nitroprusside NaNP) on the accumulation and degradation of oxidized LDL (ox-LDL) by macrophages were studied. Ox-LDL, but not native-LDL (n-LDL) suppressed the LPS-stimulated bi...
Role of histamine in regulation of blood flow in the injured gastric mucosa of the cat [0.03%]

Superficial mucosal damage caused by a mild irritant (2 M NaCl) results in release of histamine and probably prostaglandins giving increased GMBF. This hyperemic response contributes to protect the mucosa during the early phase of repair af...
Nitric oxide is involved in the mediation of gastric blood flow and tissue oxygenation [0.03%]
一氧化氮参与胃血流量和组织氧合作用的中介调节作用

Endogenous nitric oxide which is enzymatically formed by endothelial cells from L-arginine has been implicated in the control of gastrointestinal circulation. Its role in the mediation of gastric tissue oxygenation has not been studied. We ...
Functional and structural changes of isolated rat parietal cells during membrane potential modulation [0.03%]

The present experiments were undertaken to extent our earlier observations (J Physiol Pharmacol 1991, 42, 367-79) relating membrane potential with membrane recycling of parietal cells. Studies were performed in vitro using gastric glands th...
Role of Helicobacter pylori infection in gastro-duodenal secretion and in pathogenesis of peptic ulcer and gastritis [0.03%]
幽门螺杆菌感染在胃肠液分泌、消化性溃疡和胃炎发病机制中的作用

Etiologic role for HP appears to be best established in histologically proven gastritis. The major factors mediating gastritis induced by the colonization of the "gastric type" mucosa with HP are probably cytotoxins, cytokines and free radi...
Cholecystokinin in the control of gastric acid and plasma gastrin and somatostatin secretion in healthy subjects and duodenal ulcer patients before and after eradication of Helicobacter pylori [0.03%]

Background: Exogenous cholecystokinin (CCK) is known to effect gastric secretory and motor functions but its physiological role in the control of these functions in healthy subjects and duodenal ulcer (DU) patients is unk...
