متن کاملHormone-induced calcium oscillations in liver cells can be explained by a simple one pool model.
Hormone-induced oscillations of the free intracellular calcium concentration are thought to be relevant for frequency encoding of hormone signals. In liver cells, such Ca2+ oscillations occur in response to stimulation by hormones acting via phosphoinositide breakdown. This observation may be explained by cooperative, positive feedback of Ca2+ on its own release from one inositol 1,4,5-trisphos...
متن کاملA QUANTUM CHEMICAL STUDY OF STRUCTURE -ACTIVITY RELATIONSHIPS OF DIHYDROPYRIDINE CALCIUM ANTAGONISTS
Quantum chemical (MNDo)caleulations have beenused toelucidate the molecular properties and structure - activity relationships of dihydropyridine (DHP) type calcium antagonists. There is a good corielation between the net atomic charges on various atoms of the 4 - phenyl ring of dihydropyridines and pharmacological activity. .Also, activity decreases with increasing free rotation of the phen...
متن کاملEffects of veratridine on Ca fluxes and the release of oxytocin and vasopressin from the isolated rat neurohypophysis
Uptake of radioactive calcium, 45Ca efflux, and hormone release from the isolated rat neurohypophysis were monitored in vitro after the addition of veratridine to the incubation medium. Veratridine dramatically increased hormone release, but the release was not sustained and had declined by about 90% after 2 h. Removal of external Na+ prevented hormone release as did addition to the incubation ...
متن کاملThe Antiiflammtory Activity of calcium-channel antagonists on chronic inflammation in rat
calcium mobilization is known to be an important factor in the activation of cells involved in inflammation,so,calcium-channel antagonists are be expected ti exhibit antiinflammatory activity.in the present study,we evaluateted the antiinflammatory effects of two calcium channel blockers,verapamil and nifedipine on adjuvant induced chronic in flammation in rat paw.sixty adult male rats were div...
