Protein synthesis inhibition by cycloheximide does not affect the acute release of tissue-type plasminogen activator

The acute release of tissue-type plasminogen activator (t-PA) was studied in perfused rat hindlegs. Pretreatment of rats with the protein synthesis inhibitor cycloheximide (2 mg/kg) at 1, 3 or 5 h prior to perfusion of rat hindlegs did not influence the amount of t-PA released by platelet-activating factor (20 nM) or bradykinin (1 μM). The...

Hypocoagulant and lipid-lowering effects of dietary n-3 polyunsaturated fatty acids with unchanged platelet activation in rats

We investigated the effects of dietary polyunsaturated fatty acids (PUFAs) on blood lipids and processes that determine hemostatic potential: platelet activation, coagulation, and fibrinolysis. For 8 to 10 weeks, Wistar rats were fed a high-fat diet containing various amounts (2% to 16%) of n-3 PUFAs derived from fish oil (FO) or a diet enriched...
