The aim of present study was to define the cellular mechanisms underlying changes in delayed rectifier K⁢ (KDR) channel function in isoproterenol-induced hypertrophy. It has been proposed that KDR channels play a role in regulation of vascular tone by limiting membrane depolarization in arterial smooth muscle cells. The alterations of the properties of coronary KDR channels have not been studied as a possible mechanism for impaired coronary reserve in cardiac hypertrophy. The present...

To define the postnatal changes in ANP secretion in response to mechanical stretch and atrial compliance, experiments have been done in perfused nonbeating rabbit atria with different ages: 1-day, 1-, 2-, 3-, 4-, and 8-wk-old. In 1-day-old-rabbits, an increase in intraatrial pressure resulted in an increase in atrial volume, which was higher than that in 1-wk-old rabbits. Increases in atrial volume stimulated the secretion of ANP with concomitant translocation of extracellular fluid (ECF) into...

in vitro also attenuated ICa,L (8.40.4 pA/pF, P＜0.01). The amplitude of Ito on depolarization to 60 mV was reduced in endotoxin treated myocytes (16.51.5 pA/pF, P＜0.01, ex vivo; 20.00.9 pA/pF, P＜0.01 , in vitro) compared to normal myocytes (control; 24.71.0 pA/pF). There was no voltage shift in steady-state inactivation of ICa,L and Ito between groups. These results suggest that endotoxin reduces Ca2⁢ and K⁢ currents of rat cardiac myocytes, which may lead to cardiac dysfunction.

Interactions among dexamethasone, dehydroepiandrosterone (DHEA), lipopolysaccharide (LPS), and antimycin A on the glutamate uptake and the polyamine uptake were investigated in primary cultures of rat cerebral cortical astrocytes to examine the effects of dexamethasone and DHEA on the regulatory role of astrocytes in conditions of increased extracellular concentrations of glutamate or polyamines. 1. [3H]Glutamate uptake: LPS and antimycin A decreased Vmax, but both drugs had little effect on...

in the spinal cat than in the cat with intact spinal cord. The responses of WDR cell to thermal stimulation were also strongly inhibited. Dopamine D2 receptor antagonist, sulpiride, but not D1 receptor antagonist, significantly blocked the inhibitory action of dopamine on the C-fiber and thermal responses of dorsal horn cells. These findings suggest that dopamine strongly suppresses the responses of WDR cells to afferent signals mainly through spinal dopamine D2 receptors and that spinal...

from 5.7⁑0.2 cycles/min to 6.5⁑0.2 (n=22). Voltage-operated Ca2⁢ currents were decreased by PGE2 (n=5). Voltage-operated K⁢ currents, both Ca-dependent and Ca-independent, were increased (n=5). These results suggest that PGE2 plays an important role in the modulation of gastric smooth muscle activities, and its inhibitory effects on the contractility and activities of slow waves are resulted from both decrease of Ca2⁢ currents and increase of K⁢ currents.
