1. [Neovir, an interferon inductor, modifies expression of steroid hormone receptors in hormone-dependent tissues and restores sensitivity to tamoxifen in patients with inoperable breast cancer].
A low-molecular inductor of interferon-neovir-was found to increase the expression of estrogen and progesterone receptors in the uterus of ovariectomized rats weighing 210-230 g. It also gave more edge to progesterone receptors and reduced the receptor-reducing effect of tamoxifen in relatively young rats weighing 120-140 g. Sensitivity of breast tumor tissue to tamoxifen was restored and a 60-170 day-long period (observation time) of stabilization of the process ensued in 8 out of 10 patients, following administration of a total dose of 2,000 mg neovir (during one month) to patients with extensive breast tumors resistant to tamoxifen.
2. [Effectiveness of a new Soviet drug Benzonal, inductor of microsomal enzymes of the liver, in the complex treatment of hemolytic disease of newborn].
The effects of benzonal on the course of neonatal hemolytic disease due to the Rhesus factor-conflict was studied in comparison with that of phenobarbital. Dynamic follow-up of infants in the early neonatal period showed benzonal to produce a more pronounced hypobilirubinemic effect which was manifested as a prompter disappearance of skin jaundice and lower percentages of complications. By depressing the activity of organospecific enzymes and lowering the serum biliary acid levels, benzonal promotes normalization of the metabolic shifts present in neonatal hemolytic disease. The findings make it possible to recommend the new inductor of microsomal liver enzymes benzonal as part of the combined therapy of neonatal hemolytic disease.
