In previous studies, we measured a greater intracellular free calcium concentration and net potassium efflux, possibly calcium activated, in lymphocytes from spontaneously hypertensive stroke-prone rats (SHRSP) as compared with Wistar-Kyoto (WKY) rats. In this study, we addressed two related questions: 1) Can the greater intralymphocytic calcium concentration of the SHRSP account for the greate...

Lenses obtained from rats on a galactose diet for six days showed a marked reduction in their capacity to incorporate 35S-methionine into protein even though there was no reduction in the capacity of the lenses to incorporate 3H-thymidine and 3H-uridine into DNA and RNA, respectively. Therefore, lenses were incubated in media in which various putative cataractogenic factors were varied to deter...

in order to evaluate different sources and rates of nitrogen on dry matter yield, concentration and uptake of primary macronutrients (nitrogen, phosphorous and potassium) in forage sorghum (hybrid of speedfeed), three levels of nitrogen (80, 160 and 240 kg n ha-1) from three n sources (urea fertilizer, cattle manure and equal combination of urea fertilizer + cattle manure) and the control (no f...

MALNIC, GERHARD, RUTH M. KL~SE, AND GERHARD GIEBISCH. Microperfusion study of distal tubular potassium and sodium transfer in rat kidney. Am. ,J. Physiol. 2 I I (3) : 548359. 1966. The ability of proximal and distal tubules to establish limiting transepithelial electrochemical potential gradients was tested in stationary microperfusion experiments in vivo. Droplets of isoosmotic rafhnose soluti...

Ciliary ganglion neurons, half of which normally suffer developmental death in the embryo, will survive in culture in medium supplemented with depolarizing concentrations of potassium. It is not known how elevated potassium acts inside the cell to promote survival. We report here that depolarizing concentrations of extracellular potassium promote neuronal survival by causing a sustained increas...

Race and Sex Differences in the Effects of Dietary Potassium Intake on the Risk of Stroke To the Editor: We read with great interest the 2 articles by Fang et al1 and Bazzano et al2 on the association between dietary potassium intake and stroke mortality. The study by Fang et al has revealed an inverse association between hazard of stroke death and dietary potassium intake in hypertensive men a...

abstract the whole blood potassium concentration has shown the bimodal distribution in sheep, which has been classified into lk and hk types; hk allele is recessive to lk with a single gene inheritance. this polymorphism showed different behavior in different environment, which could be due to adaptation process. this research was conducted on the zel and kermani breed research station, which k...
