background: previous studies have shown increases in endothelin (et) concentration of plasma and renal tissues in acute renal failure (arf).  et has a potent vasoconstrictor effect, through binding with its et a receptors, and may play some roles in renal hemodynamic dysfunction in arf. objective: to examine the beneficial effect of a selective et a -receptor antagonist on renal dysfunction and...

Objective(s): Some histopathological alterations take place in the ischemic regions following brain ischemia. Recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. Here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...
