To examine the effects of zinc gluconate (ZG) on the nephrotoxicity of cis-platin (CDDP), changes in renal function and glutathione metabolism were investigated in mice. Fifty mice were randomly divided into five equal groups: controls, CDDP group and three ZG plus CDDP groups; the dose of ZG was 100 mg, 140 mg and 180 mg/kg respectively. Mice were sacrificed after 48 hours of CDDP (9 mg/kg) treatment; the levels of serum creatinine (Cr) and blood urea nitrogen (BUN) were measured, the glutathione (GSH) and malondialdehyde (MDA) content and the activities of glutathione peroxidase (GHS-PX) and catalase (CAT) in whole blood and renal tissue were assayed. Compared to the control group, there were significant increases in Cr, BUN and MDA, and decreases in the activities of GSH-PX in the CDDP group in whole blood and renal tissue. Preadministration of ZG at the doses of 140 mg/kg and 180 mg/kg significantly increased the concentration of GSH in whole blood, and decreased the levels of Cr and BUN, and the MDA content in whole blood and renal tissue, compared with the CDDP group. We conclude that preadministration of ZG might improve renal function and glutathione metabolism and reduce the nephrotoxicity of cis-platin.

D008815	Mice, Inbred Strains	Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D001806	Blood Urea Nitrogen	The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

D002374	Catalase	An oxidoreductase that catalyzes the conversion of HYDROGEN PEROXIDE to water and oxygen. It is present in many animal cells. A deficiency of this enzyme results in ACATALASIA.	Catalase A,Catalase T,Manganese Catalase,Mn Catalase
D002945	Cisplatin	An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
