Stimulation of Structural and Functional Recovery of the Kidney in Rats with Postischemic Acute Renal Failure of Different Severity by Embryonic Protein-Peptide Complex Therapy.

In male rats, acute renal failure was simulated by clamping the vascular pedicle of the left kidney for 60 or 90 min and right-sided nephrectomy. In the control series, no therapy was performed. In the experimental series, the animals were daily injected subcutaneously with Cellex, a protein-peptide complex (PPC) chromatographically isolated from the brain tissue of pig embryos with a molecular weight of its components from 10 to 250 kDa.

Role of oxidative stress and mitochondria in onset of urinary bladder dysfunction under acute urine retention.

Acute urine retention is a frequent complication in patients with benign hyperplasia of the prostate gland. According to studies made on experimental animals and people, it is accompanied by the deterioration of the bladder blood supply. This study attempts to explore the relationship of intramural blood flow, production of reactive oxygen species, and functional state of the bladder detrusor in modeling of acute urine retention in rats, as well as the impact of mitochondria-targeted antioxidants (which are supposed to alleviate the effects of oxidative stress induced by experimental ischemia) on these parameters.

Comparative analysis of secretory and reabsorbing activity of ileal and sigmoid mucosa, employed for urinary bladder intestinoplasty.

In experiments on rats we studied reabsorption and secretory activity of the mucosa in isolated segments of the ileum and sigmoid colon used for urinary bladder intestinoplasty after cystectomy. Ileal mucosa was found to retain high metabolic activity under changed conditions. It reabsorbs urea, creatinine, potassium, sodium, chlorine, phosphorus, calcium, glucose, and uric acid from the urine and secretes magnesium, iron, and proteins into the urine.

[Food additive urisan in combined treatment of urolithiasis].

Thirty three urolithiasis patients (13 males, 18 females aged 29-77 years, 2 children, duration of the disease 1-17 years) received food additive urisan in combined treatment of urolithiasis. Blood and urine biochemistry was studied by 11 parameters to evaluate renal function and lithogenesis before and after intake of urisan. Standard treatment was combined with intake of 2 capsules (1100 mg) of urisan twice a day at meal for 2-3 weeks.

Experimental intravenous cell therapy of acute and chronic renal failure.

The therapeutic effect of intravenous injection of human fetal bone marrow mesenchymal stem cells or summary culture of kidney cells were studied on models of chronic or acute renal failure in outbred albino rats. Both cell types promoted improvement and normalization of the renal function in rats with stable chronic renal insufficiency (2 weeks after kidney cell injection, 1 month after bone marrow mesenchymal stem cell injection). Renal function remained normal or subnormal during the delayed period (3-3.
