forskolin/脳卒中

Our study was designed to determine whether NKH477, a novel, potent and water-soluble forskolin derivative, may exert a positive inotropic effect in rats with chronic heart failure (CHF) after myocardial infarction. Cardiac output and stroke volume indices were decreased and systemic vascular

We examined the effects of a novel water-soluble forskolin derivative, NKH477 (0.5 microgram/kg/min), on arterial-ventricular (A-V) coupling and mechanical energy transduction from heart to circulatory bed in comparison with those of dobutamine (3 micrograms/kg/min) in 8 patients with left

This study examined the function of adenylyl cyclase (AC) activity in the hippocampus and cerebral cortex of the stroke-prone spontaneously hypertensive rat (SHRSP). Male SHRSP (8-week-old and 25-week-old) were used for the experiments, and age-matched Wistar-Kyoto rats (WKY) were used as a genetic

Adenylate cyclase activity was investigated in either homogenate or particulate fractions from the frontal cerebral cortex of the gerbil following five experimental conditions of bilateral ischemia. After periods of 15 min ischemia, 15 min ischemia plus 15 min of recirculation or 60 min ischemia the

In the first part of this presentation, data is reported on the hemodynamic effects of forskolin given to patients with dilated cardiomyopathy in a concentration of 3 micrograms/kg/min and 4 micrograms/kg/min. At the lower dosage, forskolin had no effect on dP/dtmax, cardiac index, ejection

The relaxant effects of calcitonin gene-related peptide (CGRP) and other drugs were compared in basilar artery rings obtained from stroke-prone spontaneously hypertensive rats (SHRSP) and Wistar-Kyoto rats (WKY). In addition, the relaxant effect of CGRP on basilar arteries from spontaneously

1. The relaxant effects of dopamine (DA) on the intrarenal arteries obtained from 6 month old stroke-prone spontaneously hypertensive rats (SHRSP) and age-matched Wistar-Kyoto (WKY) rats were pharmacologically investigated in vitro. 2. DA (10(-7)-3 x 10(-5) mol/L) produced endothelium-independent

1. The relaxant responses to calcitonin gene-related peptide (CGRP) of the 3rd order branches of the superior mesenteric arteries (SMA) from 6 month old stroke-prone spontaneously hypertensive rats (SHRSP) and age-matched Wistar-Kyoto (WKY) rats were studied in vitro. 2. Cumulative addition of CGRP

The relaxant effects of calcitonin gene-related peptide (CGRP) on the 3rd branches of renal arteries obtained from stroke-prone spontaneously hypertensive rats (SHRSP), and Wistar-Kyoto rats (WKY) were investigated in vitro. CGRP elicited concentration-dependent relaxation, and the relaxant response

Forskolin, a diterpene derivative of the Indian plant Coleus forskhohlii, proved to be a marked positive inotropic and vasodilatory compound in animal experiments with a mechanism of action distinct from catecholamines, cardiac glycosides, and phosphodiesterase-inhibiting compounds. The

We are studying a Turkish family with autosomal-dominant hypertension and brachydactyly; affected persons die of stroke before 50 years of age. With interphase fluorescence in situ hybridization, we found a chromosome 12p deletion, reinsertion, and inversion in affected persons. This finding

The Ca2+ responsiveness of vascular smooth muscle myofilaments is not unique: it is increased during neuro-humoral activation and decreased during beta-adrenergic stimulation. In this study we tested whether an augmented Ca2+ responsiveness of smooth muscle myofilaments may contribute to the

Long-term moderate consumption of red wine is associated with a reduced risk of developing lifestyle-related diseases such as cardiovascular disease and cancer. Therefore, resveratrol, a constituent of grapes and various other plants, has attracted substantial interest. This study focused on one

The spontaneous microaggregation of platelets (SMAPs) is a marker for the prognosis of patients with cardiovascular diseases. Coupling factor 6 (CF6) binds to the plasma membrane ATP synthase and functions as a pro-atherogenic molecule in the cardiovascular system. However, the role of CF6 in SMAPs

Though antiplatelet drugs are proven beneficial to patients with coronary heart disease and stroke, more effective and safer antiplatelet drugs are still needed. In this study we report the antiplatelet effects and mechanism of BF0801, a novel adenine derivative. BF0801 dramatically inhibited
