Hypovolemic hemorrhagic shock was induced in male anesthetized rats by intermittently withdrawing blood from an iliac catheter over a period of 20 min until mean arterial pressure (MAP) fell to 30 mm Hg. Survival rate, MAP, plasma myocardial depressant factor (MDF) activity and plasma levels of both TxB2 and 6-keto PGF1 alpha were then evaluated.(More)
Splanchnic artery occlusion (SAO) shock, induced by a transient occlusion of splanchnic arteries for 45 min, was performed in male rats, treated with vehicle or cloricromene, a coumarin derivative, 15 min before surgery. Survival rate, plasma levels of myocardial depressant factor (MDF), macrophage phagocytosis and killing of Candida albicans, and(More)
Splanchnic artery occlusion shock was induced in anesthetized rats by clamping the splanchnic arteries for 45 min. The survival rate, plasma levels of thromboxane B2 (TxB2) and 6-keto-PGF1 alpha, serum and peritoneal levels of macrophage tumor necrosis factor (TNF alpha), the phagocytotic and killing activity of peritoneal macrophages and white blood cells(More)
Splanchnic artery occlusion (SAO) shock, produced by clamping splanchnic arteries for 45 min followed by the release of occlusion, was induced in male rats, treated 15 min before surgery, with fructose 1,6-diphosphate (FDP) or with equivalent doses of fructose or inorganic phosphate. Survival rate, peritoneal macrophage phagocytosis and plasma levels of(More)
The effects of a daily administration of an anti-converting enzyme inhibitor. Captopril (CPT) (100 mg/kg/orally), on the development of functional and morphological alterations induced in rats by a single injection (7.5 mg/kg/iv) of Doxorubicin (DXR) (Adriamycin*), were investigated. Twenty-four-hour protein excretion, urine output, food intake, water(More)
The possible synergistic effect of valproic acid and ethosuximide in combination on pentylenetetrazole-induced epilepsy was investigated in rats. Valproic acid and ethosuximide administered intraperitoneally both showed dose-dependent anti-epileptic activity towards pentylenetetrazole-induced myoclonias and tonic-clonic seizures. The valproic(More)
14 male Wistar rats were studied, before and after pentylentetrazol (PTZ) 20 mg/kg i.p., since a petit mal-like electroclinical pattern, either spontaneous or PTZ-induced was recently described in a breeding station where this strain is raised. In particular, surface EEG, muscular, respiratory and cardiac activities were recorded in order to detect possible(More)
Splanchnic artery occlusion (SAO) shock made by clamping splanchnic arteries for 45 min was performed in female rats infused for 30 min with vehicle, nimodipine, and verapamil before, during, or after SAO. Survival time, macrophage phagocytosis and killing, and white cell count were evaluated in conscious rats. Shocked animals pretreated with vehicle(More)
The effects of intracerebroventricular (i.c.v.) injection of alpha-human atrial natriuretic peptide (alpha-hANP) and alpha-rat atrial natriuretic peptide (alpha-rANP) were studied in normotensive [Wistar-Kyoto (WKY)] and spontaneously hypertensive rats (SHR). Intracerebroventricular injection of alpha-hANP (200, 400, and 800 ng in 5 microliters) did not(More)
