Purpose: The aim of this study to investigate the effect of progestrone and calcium ionophore (A23187) on mouse sperm parameters and fertilization rate. Materials and Methods: Csauda epididymidis were then obtained from NMRI male mice (10-12 wk old) and were divided to three groups: Control, adding progesterone (10µg/ml) and addingionophore (10mM) After sperm were prepared and incuhated in T6 ...
The purpose of this investigation was to determine whether cells transformed by herpes simplex virus type 2 (HSV-2) can be stimulated to synthesize prostaglandins (PG). Stimulation was determined by measuring the release of PG into overlay fluids from cell monolayers prelabeled with [3H]arachidonic acid. Re sults showed that Ca2+ ionophore A-23187 markedly stimulated arachidonic acid release st...
The secretion of the dense granule constituents ATP. ADP, calcium. pyrophosphate (PP,). and orthophosphate (PJ. and the release of magnesium induced by thrombin and the divalent cation ionophore A231 87 have been quantitated directly in gel-filtered platelets from patients with storage pool deficiency (SPD). Both the contents and the maximal amounts of the dense granule constituents secretable ...
1. Preparations ofmouse ascites-tumour cells depleted ofATP and Na+ ions accumulated L-methionine, in the presence of cyanide and deoxyglucose, from a 1mm solution containing 80mequiv. of Na+/1 and about 5mequiv. of K+/l. Valinomycin increased, from about 4 to 16, the maximum value of the ratio of the cellular to extracellular concentrations of methionine formed under these conditions without m...
