Morphological Assessment of Prostatotropic Activity of (3,5-Dimethyl-4-Hydroxy)Benzyl Thiododecane on a Model of Benign Prostatic Hyperplasia in Rats.

Prostatotropic activity of (3,5-dimethyl-4-hydroxy)benzyl thiododecane (T-DD) was evaluated on a model of benign prostatic hyperplasia induced in Wistar rats by chronic (2 months) intraperitoneal administration of sulpiride (40 mg/kg). Morphometric analysis of the dorsolateral lobe of the prostate showed that after the 2-month course of intragastric T-DD (100 mg/kg) administered in parallel with sulpiride, the volume density of glandular epithelium decreased by 1.7 times, while the volume density of prostate stroma increased by 2 times.

Effect of 3-(3'-tert-butyl-4'-hydroxyphenyl)propyl thiosulfonate sodium on expression of GSTP1 and NQO1 genes and protein transcription factors in BALB/c mouse liver.

The study examined dynamics of the effect of novel phenol antioxidant preparation 3-(3'-tertbutyl- 4'-hydroxyphenyl)propyl thiosulfonate sodium (TS-13) on expression of antioxidant protection enzymes genes GSTP1 and NQO1 and on the content of protein transcription factors NF-κB and ATF-2 in mouse liver. Expression of GSTP1 gene decreased significantly on days 4 and 7 after per os administration of TS-13 (100 mg/kg), but increased on post-administration day 14. On days 7 and 14 post-administration, expression of NQO1 gene was significantly increased.

[Hepatoprotective effect of thiophane in rats with experimental carbon tetrachloride-induced hepatitis].

A hepatoprotective effect of thiophan was studied on the model of carbon tetrachloride-induced hepatitis in rats. Therapeutic administration of thiophan repairs the antitoxic function of liver, normalizes cytolysis marker activity, and improves the synthetic function of liver and the carbohydrate and lipid metabolism. The hepatoprotective activity of thiophan is similar to effect of silimarin.

[Pharmacological correction of the cytogenetic effects of cisplatin].

Beginning with the first hours of experiments, cisplatin evoked an increase of chromosomal aberrations in CBA/CaLac bone marrow cells. Significant increase of structural infringements of chromosomes due to chromatid breaks was revealed in metaphase plates of murine bone marrow preparations through 24 h after cisplatin intraperitoneal introduction. In late terms of research (90th day), the high level of aberrations of chromosomes was retained.

Effect of phenol inducing the antioxidant responsive element on Drosophila melanogaster lifespan.

The effect of hydrophilic synthetic antioxidant TC-13 (3-(3'-tert-butyl-4'-hydroxyphenyl)propylthiosulfonate sodium) inducing the antioxidant-responsive element on the lifespan of Drosophila melanogaster was studied. Addition of 1% TC-13 to diets prolonged the lifespan of long-lived D. melanogaster Canton S strain females and males, but not of short-lived Oregon R insects and reduced the mean lifespan of D.
