Heparin shows blood pressure lowering effect in hypertensive patients and animal models. The present study examined the effect of heparin on vasoconstrictor endothelin-1 (ET-1) production in cultured human umbilical vein endothelial cells (ECs) to elucidate the mechanism of antihypertensive effect of heparin. Heparin suppressed both basal and(More)

This study describes the effect of heparin on blood pressure, cardiac output, and total peripheral resistance in spontaneously hypertensive and one-kidney, one clip Goldblatt hypertensive rats. Administration of heparin (200 units/day/rat) for 8 weeks to young (6-week-old) spontaneously hypertensive rats (SHR) resulted in an attenuated rise in blood(More)
Hypernatremia (serum sodium level of > 145 mEq/L) is associated with high mortality. This study reports an analysis of mortality in 116 patients with hypernatremia from two large university-affiliated teaching hospitals. The purpose was to identify factors predictive of high mortality in hypernatremic patients. Medical records were reviewed to obtain the(More)
Muscle cramp is a recurrent and painful condition and a common complaint among elderly subjects and patients treated with hemodialysis. It is commonly nocturnal and can disturb a good night's sleep. No specific cause can be identified; therefore, therapy is mostly symptomatic. Quinine sulfate, an antimalarial drug, is widely used as an effective therapy for(More)
