A modified ethanol injection method for liposomes containing soybean phosphatidylcholine (SPC), cholesterol (Ch), beta-sitosterol beta-D-glucoside (Sit-G) and oleic acid (OA) was developed, that can produce homogeneous unilamellar liposomes without the use of sonication and dialysis. In this method, water is poured into a concentrated lipid-ethanol solution(More)
The purpose of this study was to investigate the actions of estradiol on spontaneous and evoked action potentials in the isolated longitudinal smooth muscle cells of the pregnant rat. Single cells were obtained by enzymatic digestion from pregnant rat longitudinal myometrium. Action potentials and currents were recorded by whole-cell current-clamp and(More)
The purpose of this study was to investigate the actions of 17beta-estradiol on the electrical activity of pregnant rat myometrium. The longitudinal layer of the myometrium was dissected from pregnant rats (17 to 19 days of gestation), and single cells were isolated by enzymatic digestion. Calcium currents and potassium currents were recorded by the(More)
1. Dorsal epithelium of the frog tongue produced a change in potential difference across the tissue in response to removal of NaCl from the adapting Ringer solution on the mucosa. 2. The response was not caused by an osmotic decrease in the stimulus, and its profile was in many respects similar to that of the receptor potential in frog taste cells. 3. In(More)
1. Open-circuit potential difference and short-circuit current across the frog tongue epithelium in response to glycinamide and glycylglycinamide were investigated. 2. Response to both of these amides were larger than the responses produced by glycine, glycylglycine and NaCl, and were independent of Na+ in the mucosal medium but dependent on H+ in the(More)
