The gold standard for the treatment of invasive bladder cancer recognized throughout the world is radical cystectomy with orthotopic ileocystoplasty using the ileal intestinal tract. The study of the effect of urine on the adaptation of the mucosa of the artificial bladder continues for the last twenty years. According to the researchers, the results are quite contradictory, as some scientists note the hypersecretion of sulphomucins, sialomucins, progressive atrophy of microvilli, adenomatous hyperplasia and dysplasia.

We studied the effect of Quercetin on energy profile of erythrocytes of rats with the overactive bladder syndrome. It was shown that animal models with the subject pathology demonstrated alteration of quantitative composition of the adenine nucleotide system in erythrocytes. Abrupt decrease of the total concentration of adenyl nucleotides and ATP compared to the intact group of animals was noted in the study.

Results of study into the condition of reduction-oxidation processes, in particular of those associated with generation of the superoxide radical, are submitted together with those of determination of levels of inorganic phosphate which is known to be an important indicator of the tissue bioenergy potential, in 112 patients presenting with a recurring form of nephrolithiasis exposed to a multiple-modality treatment that included conventional antiinflammatory and antibacterial therapy plus "open" and endourological operations on kidneys and ureters. The multiple-modality treatment of the main group patients was supplemented with phlogenzyme, a drug of II generation systemic enzymotherapy. An enhanced generation of superoxide radical was recordable having developed in the wake of a steady increase in the activity of xanthinoxidase.

Clinical data are presented on a new anti-alcoholic drug, litonit. A substantial reduction in the pathological addiction to alcohol takes place under the effect of litonit, and a stable aversive reaction to alcohol develops. The new drug is distinguished by its low toxicity, good tolerance, and its failure to cause disorders of the liver and kidneys even after chronic administration.

The results of 250 experiments suggest the advisability of using a new antialcoholic metabolite drug, litonit, in combined therapy of infectious-inflammatory kidney disorders occurring in alcoholism. The course of litonit injections does not only increase considerably the content of oxidized and reduced nicotinamide coenzymes, but also normalizes the number of IgA, IgG and IgM. Certain drug-induced functional and immunological shifts are now believed to indicate the increase in the functional renal capacity and enhanced kidney resistance to inflammation.
