We measured cytochrome b5 reductase (EC 1.6.2.2) activity in erythrocytes and leukocytes from subjects of both sexes ranging in age from neonate to adulthood, all either apparently healthy or without hematologic disorders. The activities were determined spectrophotometrically (J. Lab. Clin. Med. 72: 339-344, 1968). Within-run precision (CV) of the reductase determination was 6.4% and 3.7% for e...

The function bk(n) is defined as the number of partitions of n that contain no summand divisible by k. In this paper we study the 2-divisibility of b5(n) and the 2and 3-divisibility of b13(n). In particular, we give exact criteria for the parity of b5(2n) and b13(2n).

The effect of malotilate (diisopropyl 1,3-dithiol-2-ylidenemalonate) on drug metabolizing activity in rat liver microsomes was examined. Malotilate (500 mg/kg/day) was administered orally to rats for 3 days. The contents of cytochrome P-450 (P-450) and cytochrome b5 (b5), the activity of NADPH-cytochrome c reductase, and the metabolization of aniline, aminopyrine, benzo(a)pyrene (B(a)P) and 7-e...

In this work, we measured the effect of cytochrome c on the NADH-dependent superoxide anion production by synaptic plasma membrane vesicles from rat brain. In these membranes, the cytochrome c stimulated NADH-dependent superoxide anion production was inhibited by antibodies against cytochrome b5 reductase linking the production to this enzyme. Measurement of the superoxide anion radical generat...

One hundred and thirty seven unrelated Nadar individuals residing in Tamil Nadu, (South India) were studied for HLA A, B, C and DR locus antigen profiles. The allele frequencies of HLA A9, B5, Cw4, Cw7, DR2 and DR6 were increased while frequencies of HLA A10, B8, B16, B46, B78, Cw5, Cw9 and DR9 were decreased in the Nadars. The gene frequencies of HLA A1, A3, A28, B5, B17, B37, Cw4, Cw5, DR1, D...

OBJECTIVES Cytochrome P450 (CYP) 1A1 located in the membrane of endoplasmic reticulum is the most important enzyme in both activation and detoxification of carcinogenic benzo[a]pyrene (BaP), in combination with microsomal epoxide hydrolase (mEH). However, it is still not clearly explained how the electron transfer is mediated by NADPH:CYP oxidoreductase (POR), another component of the microsoma...

Citronella essential oil (CEO) has been reported as an excellent mosquito repellent; however, mild irritancy and rapid volatility limit its topical application. It was aimed to develop a nonirritant, stable, and consistent cream of CEO with improved residence time on skin using an industrial approach. Phase inversion temperature technique was employed to prepare the cream. It was optimized and ...

The dehydrogenation reaction of cholest-7-en-3beta-ol (I) to cholesta-5,7-dien-3beta-ol (II) in the presence of NADH was studied in rat liver microsomes and in microsomal acetone powder preparations, using [3alpha-3H]cholest-7-en-3beta-ol. It was found that the reaction was inhibited by menadione, adenosine diphosphate, potassium ferricyanide, and cytochrome c while p-cresol had no effect. Thes...
