[Functional state of a solitary kidney after nephrectomy for renal cancer].

Introduction: The outcome of surgical treatment of renal cancer depends not only on cancer-specific survival, but also on the degree of loss of renal function, which often develops after surgery, especially radical nephrectomy.

Aim: To study the features of functional changes in a solitary kidney as a compensation mechanism after radical nephrectomy for renal cancer.

Materials And Methods: The functional state of a solitary kidney in 36 patients with renal cancer who undergone to radical nephrectomy was evaluated.

[Dynamics of sperm indicators in men with chronic prostatitis associated with secondary infertility based on the use of ANDROEXPERT SV1 suppositories].

Introduction: Chronic prostatitis (CP) is the most common cause of a disorder of not only sexual, but also reproductive functions in men, which is caused by a decrease in the quality of the ejaculate and is confirmed by a deterioration in spermogram parameters, up to oligoasthenoteratozoospermia and azoospermia. In such a situation, the onset of pregnancy in the natural cycle is impossible - even with a completely preserved reproductive function in a woman. As an active substance in the recovery of men with chronic prostatitis associated with secondary infertility, we proposed oxidised dextran in the form of a pharmaceutical composition, which was developed at Federal Research Centre for Fundamental and Translational Medicine, Novosibirsk, Russia; and produced by ANDROEXPERT Research and Manufacturing Company LTD, Novosibirsk, Russia.

Low levels of dehydroascorbic acid in uraemic serum and the partial correction of dehydroascorbic acid deficiency by haemodialysis.

Background: Vitamin C is currently considered a potent water-soluble antioxidant and it appeared reasonable to study the metabolic changes of vitamin C in uraemia and during haemodialysis.

Methods: We measured the levels of ascorbic, dehydroascorbic and diketogulonic acids in sera of uraemic patients before and during haemodialysis, using the 2,4-dinitrophenylhydrazine method.

Results: The results indicate that the levels of ascorbic and dehydroascorbic acids in uraemic sera are low in comparison with controls, but the levels of diketogulonic acid are higher than in healthy persons.
