Phasic Oscillations of Extracellular Potassium (Ko) in Pregnant Rat Myometrium
K-sensitive microelectrodes were used to measure K(+) within the extracellular space (K(o)) of pregnant rat myometrium. Contractile activity was monitored by measuring either force or bioelectrical signals. Single and double-barreled electrodes were used. Double-barreled electrodes allowed monitoring of electrical activity 15 microns from the site of K(o) measurement. From double-barreled elect...
متن کاملThe Renal Protective Effects of Corn Silk and Feijoa by using in situ Rat Renal System
Background: Corn silk (CS) is widely used in Iranian traditional medicine and Feijoa sellowiana(FS) is a native plant widespread in the Southern parts of Iran. The aim of the present study was to assess renal protective activities of CS and FS against dosage induced injury by ecstasy (MDMA) using insitu rat renal perfusion (IRRP) system.Methods: Hydro-alcoholic extract of CS and FS (10, 20, 40 ...
متن کاملDevelopment of renal potassium excretion capacity in the neonatal rat.
We investigated the capacity of newborn rats to excrete an acute potassium load to understand the development of a renal potassium excretion system. Three groups of the rats (7-14 d) were used to collect urine periodically over 6 h after oral infusion of potassium: control (no potassium loading) and low- and high-potassium-loaded rats. In the low-potassium-loaded group, infused with about 0.6 m...
متن کاملMicropuncture Study of Renal Potassium Excretion in the Rat.
MALNIC, GERHARD, RUTH M. KLOSE, AND GERHARD GIEBISCH. Micropuncture study of renal potassium excretion in the rat: Am. J. Physiol. 206(4): 674-686. I g64.-Samples of proximal and distal tubular fluid were collected from rats maintained on a control, a low-K, or a high-K, low-Na diet. All animals received inulin-C 14. Plasma (P) and tubular fluid (TF) were analyzed for Na and K by dual-channel m...
متن کاملRenal NCC is unchanged in the midpregnant rat and decreased in the late pregnant rat despite avid renal Na+ retention.
Pregnancy is characterized by plasma volume expansion due to Na(+) retention, driven by aldosterone. The aldosterone-responsive epithelial Na(+) channel is activated in the kidney in pregnancy. In the present study, we investigated the aldosterone-responsive Na(+)-Cl(-) cotransporter (NCC) in mid- and late pregnant rats compared with virgin rats. We determined the abundance of total NCC, phosph...
