Effects of aqueous extracts of Apocynum venetum leaves (Luobuma extracts) on the blood pressure were evaluated in hypertensive animal models, such as spontaneously hypertensive rats (SHR), renal hypertensive rats and NaCl-induced hypertensive rats. In SHR, administration of Luobuma (heat-processed and unprocessed leaves) extracts at a dose of 70 mg/rat per(More)
The enzyme nitric oxide synthase mediates synthesis of nitric oxide (NO) from 1-arginine in endothelial cells. NO, also known as endothelium-dependent relaxing factor (EDRF), diffuses to smooth muscle cells where it leads to cGMP production and dilation. We characterized the potency, efficacy and time course of NG-monomethyl-l-arginine (l-NMMA) as an(More)
The uptake of 14C-labeled aminoglutethimide into the brain was investigated in the rat after intracarotid injection according to the method of Oldendorf, as well as in cisternal cerebrospinal fluid obtained by suboccipital puncture after i.v. injection of the drug. The brain uptake index of aminoglutethimide after intracarotid injection was 30.7 + 2.4%.(More)
