The relationship between calcium ions and the differentiation of human promyelocytic leukemia HL-60 cells was investigated. Proliferation of HL-60 cells incubated in calcium-free medium was inhibited without cell differentiation. On the other hand, incubation with 100 /¿Mverapamil markedly inhibited cell proliferation and caused slight cell differentiation into monocytes. Both calcium-free med...
The present study is concerned with the production of cephalosporin C by Cephalosporium acremonium C-10. Two culture media were tested for the production of antibiotic. Among these culture media M1 containing sucrose, ammonium acetate, cornstarch, sugar cane molasses, soybean meal, calcium carbonate, calcium sulphate and methyl oleate gave optimum production of cephalosporin C. The cultural con...
Parathyroid cysts were produced in rats by excessive doses of dihydrotachysterol. (DHT) and calcium acetate. Although overdoses of each DHT, calcium or their combination are believed to suppress the activity of the parathyroid cell, the present electron microscopic observation showed signs of enhanced protein synthesis and secretion of the cells in all stages of cyst formation. It seems reasona...
Tetracalcium phosphate (TTCP) Ca4(PO4)2O is one of the major powder components of self-setting orthopedic and dental cements. Traditionally, TTCP powders are produced by a solidstate process by soaking Caand P-containing precursors between 13501 and 15001C. Such procedures require expensive high-temperature furnaces and subsequent grinding of sintered particulates. Grinding not only introduces ...

It has been shown that intracellular injection of protein kinase C (calcium/phosphatidylserine/diacylglycerol-dependent protein kinase), purified from mammalian brain, or application of the tumor-promoting phorbol diester, 12-O-tetradecanoyl-13-phorbol acetate (TPA), leads to an enhancement of calcium currents in the bag cell neurons of Aplysia. We now present evidence of an endogenous enzyme i...
The mechanism that regulates luteolytic PGF2a secretion as stimulated by oxytocin is thought to involve induction of the inositol (1,4,5)-trisphosphatediacylglycerol second messenger system, which mobilizes intracellular calcium and activates protein kinase C. In Experiment 1, endometrial explants taken from heifers on d 18.5 to 19.5 postestrus had increased PGF2a secretion after treatment with...
