Acute renal hypertension is produced by the injection of the amino acid dopa (l-dihydroxyphenylalanine) into the partially or completely ischemic kidney of the cat. Evidence is presented suggesting that the rise in blood pressure following the injection of dopa is caused by its conversion into hydroxytyramine, a pressor amine. Kidneys with normal blood flow fail to transform dopa into a pressor...

To confirm that an increase in blood pressure induced by ketamine is mediated through the central nervous system, we examined effect of ketamine, applied directly to amygdala, on pressure. Six male Sprague-Dawley rats were used study. Under head-restrained and unanesthetized condition, 0.2 μl (5 mg/ml) was injected around amygdala at a flow rate μl/min glass pipette, recorded while monitoring s...

background: saffron is the dried stigmata of the flowers of saffron (crocus sativus l., iridaceae). saffron and its major active constituents, crocin (crocetin glycoside), crocetin and safranal, have a variety of pharmacological effects including high antioxidant properties and crocetin has insulin sensitizing effect possibly due to its antioxidant activity. oral crocin is not absorbed and is h...

Experiments in monkeys have demonstrated that the chronic vasospasm and arterial injury reaction produced by subarachnoid blood injection can be prevented by treatment with the phosphodiesterase inhibitor phthalazinol. This protective effect, which is present even when the drug treatment is initiated after the subarachnoid blood injection, is presumed to occur because of the platelet inhibiting...

Blood-Injury-Injection Phobia (BIIP) is a subtype of specific phobia, characterized by fear and avoidance of seeing blood, an injury, or receiving an injection. In the current case report, we describe the treatment of BIIP in a young man with mental retardation. The multicomponent treatment consisted of fading (graduated exposure), modeling, noncontingent and differential reinforcement, presess...

BACKGROUND AND PURPOSE In humans, intracerebral hemorrhage (ICH) causes marked perihematomal edema formation and neurological deficits. A rat ICH model, involving infusion of autologous blood into the caudate, has been used extensively to study mechanisms of edema formation, but an examination of behavioral outcome would improve its preclinical utility and provide a more rigorous assessment of ...

Four months back calved crossbred dairy cow had history of coffee coloured urine. Blood smear and Blood samples of this cow were collected on the day of acute stage of infection and then 15th day of post treatment for haematological parameters. Based on the clinical pathonomonic symptom (coffee coloured urine) and blood smear examination presence of Babesia bigemina organisms the disease was di...

tranexamic acid is generally used in the treatment of disorders that predispose one to bleeding. it is a synthetic lysine analog that has strong antifibrinolytic activity. plasminogen binds to fibrin to form plasmin, which in turn degrades fibrin into fibrin degradation products. tranexamic acid blocks the lysine binding site on plasminogen and prevents interaction with fibrin. tranexamic acid ...
