nimodipine, an l-type calcium channel blocker, can induce analgesia. however, it is not clear that this analgesic effect is at the level of spinal or supraspinal pain pathway. in addition, it has been reported that the analgesic effect of nifedipine, another l-type calcium channel blocker is related to the hpa axis, but there is no report indicating the role of this axis in the analgesic effect...

In a previous retrospective study, long-term treatment of essential hypertensive patients with a slow-release calcium channel blocker resulted in normal resistance artery structure and endothelial function, which did not occur with a beta-blocker. In the present prospective study, 19 previously untreated essential hypertensive patients (aged 47 +/- 2 years, 75% male) were treated for 1 year in ...

The crude extract of Carthamus oxycantha (Co.Cr) was studied in vitro for its possible spasmogenic and spasmolytic activities. Segments of isolated rabbit jejunum 2-3 cm long were mounted in Tyrode’s solution and aerated with 95% oxygen in carbon dioxide. Isotonic responses were measured on Bioscience oscillograph. Isotonic responses were measured on Bioscience oscillograph. Co.Cr caused dose-d...

The role of salt intake in the development of hypertension is prominent, but its mechanism has not been fully elucidated. Our aim was to examine the effect of transient salt intake during the prehypertensive period in hypertensive model animals. Dahl salt-sensitive rats and spontaneously hypertensive rats were fed from 6 to 14 weeks with low-salt (0.12% NaCl), normal-salt (0.8% NaCl), high-salt...

In human hypertrophic cardiomyopathy and hypertension associated ventricular hypertrophy, chronic use of calcium channel blockers results in a significant regression of hypertrophy. The main objective of this study was to test the hypothesis that modulation of calcium influx through the voltage-sensitive L-type Ca2+ channel directly affects myocardial hypertrophy. Agents that modified calcium i...

new analogues of nifedipine, as a known calcium channel blocker, were synthesized by replacing the orthonitrophenyl group on position 4 with 1-(4-nitrobenzyl)-5-imidazolyl or 2-methylthio-1-(4-nitrobenzyl)-5-imidazolyl substituent. effects of the new synthesized compounds on blood pressure were studied at 15, 30 and 60 min after administration by indirect tail-cuff method and compared with nife...
