Abstract:
Cisplatin is an effective anticancer drug used against a variety of cancers. The full therapeutic potential of cisplatin is often hampered due to concurrent development of various side effects in the hosts. Rutin, a naturally occurring bioflavonoid shows several pharmacological activities. It has been earlier reported by us that rutin and cisplatin in combination show better antitumor activity against murine ascites Dalton’s lymphoma. As cisplatin is given to cancer-bearing hosts only, the present study was undertaken to explore the histoprotective effect of rutin against some toxicities induced by cisplatin in tumor-bearing mice. Cisplatin treatment caused severe damages in tissue architecture such as degenerated hepatocytes with nuclear condensation and sinusoidal dilatation in the liver, glomerular deterioration, infiltration of cells, and tubular congestion in the kidney, and vacuolization of Sertoli cells or dense granules in the cytoplasm and damaged seminiferous tubules in the testes. In the rutin plus cisplatin combination-treated mice, all the abnormal tissue architectural features were decreased. Further, as compared to cisplatin treatment, combination treatment did not show any significant elevation in the liver functional biomarkers (serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase) and renal functional biomarkers (serum urea and creatinine levels). The combination treatment reduced the sperm abnormalities also as compared to the cisplatin alone treatment. The in vitro hemolysis assay of red blood cells and scanning electron microscopy revealed that combination treatment lessened the cisplatin-induced hemolysis and abnormalities in RBCs. Thus, the present findings demonstrate that rutin has histoprotective ability against cisplatin-induced toxicities in tumor-bearing mice.

Abstract:
Isoniazid (INH), a first-line drug in anti-tuberculosis therapy, is known to be potentially harmful and is associated with numerous side effects especially in the blood and liver. In the course of our previous investigations, 1,2,3-thiadiazole containing hydrazone (compound 3) showed excellent antimycobacterial activity against a referent strain M. tuberculosis H37Rv (MIC value 0.39 μM), low cytotoxicity, and did not have toxic effects when administered by oral or intraperitoneal routes to experimental animals (selectivity index SI > 1979, LD50>2000 mg/kg b.w.) what revealed its suitability for further exploration. In the present study compound 3 was chosen to determine its effects on the liver and kidney functions in female mice. The compound was administered orally for 14 days at three doses (100, 200, and 400 mg/kg b.w.). The quantity of malondialdehyde (MDA), the level of reduced glutathione (GSH), blood hematological and biochemical parameters were assessed, and urine analysis was carried out. As a positive control INH was used orally at a dose of 50 mg/kg b.w. The investigated compound 3 did not affect the urine and serum hematological and biochemical parameters as INH did, compared to those of the control mice. The new compound did not affect significantly the MDA quantity and maintained its level near to the control values, though lower by 36% (p < 0.05) than in the INH treated animals. At the higher doses, 200 and 400 mg/kg, it depleted the GSH content by 25% (p < 0.05), compared to the control. However, its level remained 47% (p < 0.05) higher than in the INH treated animals.
