Antioxidant properties of novel preparations--bioflavonoid derivatives and tannins

New medicinal plant preparations of polyphenol nature, representing the derivatives of bioflavonoids (piflamin) and ellagotannins (altan and ellagic acid) were experimentally studied. The drugs exhibited antioxidant properties, which were manifested by inhibition of a pathological lipid peroxidation, restoration of the functional activity of the antioxidant system components, and stabilization of the hepatocyte membranes.

The combined treatment of bladder cancer

The paper presented the results of the combined multistage treatment of 60 patients with advanced carcinoma of the urinary bladder: intra-arterial chemotherapy, immunotherapy, radiation therapy and surgery. Intra-arterial chemotherapy was performed in total dosages of the following drugs: 5-fluorouracil, 3-4 g/m2, adriamycin, 100-120 mg/m2, methotrexate, 20-40 mg/m2, platidiam, 30-50 mg/m2. Immunotherapy was exercised through endolymphatic administration of BCG vaccine in a dose of 0.08-0.12 mg. The majority of the patients were exposed to a remote gamma-therapy in a total focal dosage of 50-54 gram-roentgen. The treatment resulted in a complete regression of the tumor in 26.7, partial regression in 43.3 per cent of the patients. 3-6 mos after the radiation therapy, 46.6 per cent of the patients were operated on, mainly with the use of organ-sparing techniques. A three-year survival rate reached 100 per cent in the patients with stage T2 disease, 85.2 in those with T3a and 58.6 per cent in those with stages T3b--T4. The analysis of the survival revealed higher mortality rates in patients with low-differentiated tumors.
