In 14 patients undergoing open-heart operations the haemodynamic effects of diazepam 0.4 mgkg(-1) followed by ketamine 2 mg kg(-1) were studied. In eight patients undergoing coronary bypass surgery, the mean arterial pressure decreased significantly after diazepam from 90.3 +/-7.4 (SEM) to 78.0 +/-5.0 mm Hg (P less than 0.05). However, no changes occurred in six patients undergoing valve replac...

1 The hyperactivity syndrome produced in rats by administration of tranylcypromine (20 mg/kg i.p.) followed 30 min later by L-tryptophan (50 mg/kg i.p.) is generally considered to be due to increased 5-hydroxytryptamine (5-HT) functional activity. It is inhibited by chlorpromazine (30 mg/kg i.p.) injected 60 min before the tranylcypromine. However, chlorpromazine injection for 4 days either at ...

Objectives. We investigated whether amlodipine could improve angiogenic responses in a diabetic rat model of acute myocardial infarction (AMI) through improving bone marrow endothelial progenitor cell (EPC) mobilization, in the same way as angiotensin converting enzyme inhibitors. Methods. After induction of AMI by coronary artery ligation, diabetic rats were randomly assigned to receive perind...

The fishery of bony fishes has an economic important in southern part of Caspian Sea ,but there are few reports about the pathogens of them in this area .Eustrongylides excisus , a parasite (Nematoda: Dioctophymidae) can damage the muscles of bony fishes . So, consumers avoid to buy the infected fish. Hence , the parasite can cause economic loss.In order to determine the occurance and intensity...
