Alteration of the intracellular calcium pool of adipose tissue in spontaneously hypertensive rats. No effect of peripheral immunosympathectomy.
The intracellular calcium pool of adipose tissue was estimated by studying the kinetics of 45Ca efflux from the tissue of 9-week old spontaneously hypertensive (SHR) and normotensive Kyoto-Wistar (NKWR) rats subjected to peripheral immunosympathectomy (nerve growth factor antiserum treatment of newborn rats) and in intact (sham-treated) animals of both strains. The development of hypertension in SHR was prevented by immunosympathectomy, however, both groups, SHR-intact and immunosympathectomized rats showed an increase in the intracellular calcium content of adipocytes. These results indicate that the alteration of the membrane control over intracellular calcium distribution in adipose tissue of SHR cannot be attributed to an enhanced activity of the sympathetic nervous system.
