Bradykinin and the dextran anaphylactoid reaction in rats
Abstract:
A comparison was made of the activities of clinical dextran and bradykinin in rats. Chiefly by using antagonists, major differences were identified and the study confirmed that bradykinin is unlikely to play a major role in the dextran anaphylactoid reaction.

Overview
Antihypertensive Drugs: Angiotensin II Receptor Blockers
In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...
