An unusual case of 'uncompetitive activation' by ascorbic acid: purification and kinetic properties of a myrosinase from Raphanus sativus seedlings.
Myrosinase (thioglucoside glucohydrolase; EC 3.2.3.1) is a plant enzyme that hydrolyses glucosinolates, principally to isothiocyanates. Myrosinase was purified to homogeneity in good yield from… Expand

Substrate specificity of adrenocortical cytochrome P-450scc--I. Effect of structural modification of cholesterol side-chain on pregnenolone production.
Abstract Thirty four cholesterol analogues with modified side chain were chemically synthesized and incubated with a highly purified preparation of cytochrome P-450scc. It was shown that five to ten… Expand

Specificity of radioprotective and cytotoxic effects of cysteamine in HeLa S3 cells: generation of peroxide as the mechanism of paradoxical toxicity.
Cysteamine at 0.5-5 mM effectively kills ${\rm HeLa}\ {\rm S}_{3}$ cells, while it is much less toxic in higher concentration (30 mM). The toxicity develops gradually with time as peroxide generates… Expand

X-irradiation-induced emesis in Suncus murinus.
X-irradiation-induced emesis was investigated in Suncus murinus, a house musk shrew. Whole body X-irradiation caused emesis, and the calculated ED50 value that induced emesis in 50% of animals was… Expand

Preparation of highly purified 3α- and 3β-hydroxysteroid dehydrogenases from Pseudomonas sp
Abstract A method is described for preparing highly purified 3α- and 3β-hydroxysteroid dehydrogenases (EC 1.1.1.50 and EC 1.1.1.145, respectively), essentially uncontaminated with one another, from… Expand

Effects of recombinant human granulocyte colony-stimulating factor on the hematologic recovery and survival of irradiated mice.
We studied the effects of intraperitoneal injections of recombinant human granulocyte colony-stimulating factor (rhG-CSF) according to various administration schedules on the recovery of spleen… Expand

Intraclonal diversity of fibrosarcoma cells for the production of macrophage colony‐stimulating factor and granulocyte colony‐stimulating factor
A new cell line was established from fibrosarcoma that had spontaneously developed in a mouse. The cells were maintained growing in cultue for two years and constantly produced both macrophage… Expand
