glutathione reductase/sarcoma

A drop of glutathione peroxidase and glutathione reductase activity was revealed in sarcoma C-45 at the period of its most intensive growth. Repeated sarcolysine injections (1.2 mg/kg, intraperitoneally) caused a sharp fall in the activity of both enzymes with a simultaneous reduction of the ratio

Glutathione (GSH) metabolism and protein synthesis were observed over a period of about two weeks in Yoshida ascites sarcoma and intracellular concentration relative to days 7, 10 and 13 assumed as 'markers' of different stages of tumor development. During this period the decrease in rate of cell

We have established ten transplantable human soft-tissue sarcoma (STS) xenografts grown as subcutaneous tumours in the nude mouse. Nine xenografts originated from patients that needed chemotherapy in the course of their disease. The xenografts were tested for their sensitivity to maximum tolerated

OBJECTIVE to study the activity of antioxidant enzymes and to evaluate an intensity of prooxidant processes in sarcoma 37 (S37) cells during tumor development and under influence of sodium dichloroacetate (SDA). METHODS Activity of total superoxide dismutase (SOD), SOD isoforms, catalase (Cat),

Liposome encapsulation of saffron effectively enhanced its antitumor activity towards Sarcoma-180 (S-180) and Ehrlich ascites carcinoma solid tumors in mice. Significant inhibition (P < 0.001) in the growth of these tumors was observed as compared with vehicle (control) mice. In the presence of

The chemistry, pharmacology, pharmacokinetics, and adverse effects of ifosfamide and mesna are described separately, followed by a discussion of the adverse effects of concurrent ifosfamide and mesna, the clinical spectrum of ifosfamide, and the dosage and administration of the two drugs.

DNA extracted from 25 hamster-sheep hybrid cell lines was subjected, after Southern blotting, to hybridization with CASB, CASK, LALBA, IGF-1 and AMH cDNA probes. CASB and CASK segregated together and IGF-1 and LALBA were found syntenic with the LDHB-PEPB-TPI-GAPD-SHMT-KRTB group. No other synteny

We have previously demonstrated that hamster embryo fibroblasts (HEFs) transformed by Rous Sarcoma virus, Schmidt-Ruppin strain (RSV-SR) are highly resistant to damage by H202 (H2O2R), (in contrast to HEFs transformed spontaneously, or by bovine adenovirus and SV40), while N-ras transfection of

The isoenzyme profiles for ten enzymes of tachyzoites either grown in vivo in TG 180 mouse sarcoma cells or cultivated in vitro in human fibroblast cell culture were compared in eight cloned strains by means of isoelectric focusing in polyacrylamide gels. Fibroblast-cultivated tachyzoites of all

Specific chromosomes of sheep have been selectively "captured" in hamster x sheep cell hybrids produced by fusing different Chinese hamster auxotrophs with lymphocytes from sheep carrying normal or Robertsonian translocation chromosomes. A minipanel has been established comprising sheep chromosomes

The bark of Saraka asoca (asoka) is commonly used to treat various diseases by the Indian system of medicine and in Sri Lanka. Further purification and chemical analysis of the active compound from the bark extract of asoka showed that (-)-epicatechin was responsible for the observed
