Evaluation of the Possibility of Correction of Doxorubicin-Induced Chronic Heart Failure in the Experiment with 3-Hydroxypyridine Acetylcysteinate and 3-Hydroxypyridine Succinate.

The possibility of correction of morphological changes in the myocardium and biochemical parameters of the blood with 3-hydroxypyridine acetylcysteinate in a dose of 25 mg/kg was studied in the model of doxorubicin-induced chronic heart failure in rats. It was found that 3-hydroxypyridine acetylcysteinate in a dose of 25 mg/kg produced less pronounced cardio-protective effect in experimental chronic heart failure than 3-hydroxypyridine succinate.

[Comparative value of molecular forms of prostate-specific antigen in diagnosis of prostatic cancer].

The aim of the study was to compare diagnostic significance of free PSA (fPSA)/total PSA (tPSA) versus PSA complex with alpha1-antichymotrypsin (cPSA) in tPSA level within 4-10 ng/ml in differential diagnosis of prostatic cancer (PC). A complete urological examination (digital rectal test, transrectal ultrasound investigation, serum assay for fPSA and tPSA, multifocal transperineal prostatic biopsy) was made in 108 patients with tPSA blood level 4-10 ng/ ml. Prostatic adenoma (PA) was histologically verified in 61 of 108 patients, fPSA/tPSA was normal.
