Vascular prostaglandin synthesis: the early days.

Journal Title: Pharmacological Reports - Year 2006, Vol 58, Issue 0

Abstract

Prostacyclin (PGI(2)) and thromboxane (TxA(2)) labile cyclooxygenase (COX) products via PGH(2) were identified in biological fluids by the ingenious application of the principle of parallel pharmacological assays developed by John Vane. Either organ perfusates or circulating blood superfuse bioassay tissues arranged in a cascade. Tissues were selected based on specificity of responses to targeted eicosanoids. Additionally, PGI(2) inhibited platelet aggregation, a finding that led to discovery of its critical anti-thrombotic activity at the blood-endothelial interface. The biological activities of PGI(2) and TxA(2) were the fingerprints for tracking their isolation and ultimate chemical identification. These studies were responsible for opening the modern era of vascular biology that has facilitated the development of a rational approach to the treatment of diabetic and hypertensive complications involving the arterial circulation.

Effects of co-administration of fluoxetine and risperidone on properties of peritoneal and pleural macrophages in rats subjected to the forced swimming test.

Literature data show that administration of atypical antipsychotic drug, risperidone (RIS), enhances antidepressive action of fluoxetine (FLU). As antidepressive treatments also regulate immune functions, we examined whe...
