Abstract:
Objective To evaluate the effect and mechanism of tribulus terrestris in kidney calcium oxalate stone in rats.Methods Sisty healthy male Wistar rats were divided into control group,model group,low-dose prevention group,high-dose prevention group,low-dose treatment group,high-dose treatment group by random number table method,each group of 10 rats.The control group was had free access to water,the model group was given 1％ ethylene glycol had free access to water,and the low-dose prevention group was given 1％ ethylene glycol had free access to water while was added in Tribulus terrestris extract 250 mg/(kg · d) treated by gavage,the high-dose prevention group was given 1％ ethylene glycol had free access to water while was added in Tribulus terrestris extract 500 mg/(kg · d) treated by gavage.The low-dose treatment group received 1％ ethylene glycol had free access to water while was added in tribulus terrestris extract 250 mg/(kg · d) treated by gavage on the 15th day.The high-dose treatment group received 1％ ethylene glycol had free access to water while was added in tribulus terrestris extract 500 mg/(kg · d) treated by gavage on the 15th day.At the end of the experiment on the 28th day,the body weight,blood urea nitrogen,creatinine,P,Ca2+,Mg2+ content,24 h urine volume,24 h urine Ca2+,Mg2 +,P,oxalic acid secretion,renal tissue homogenate detection of superoxide dismutase (SOD),glutathione peroxidase (GPX),malondialdehyde content of each group were detected.The crystal deposition and pathological changes of calcium oxalate were observed under the microscope.Measurement data were expressed as mean ± standard deviation (Mean ± SD),multiple comparisons between groups were performed using LSD-t test,and comparison between groups was performed by one-way anova analysis of variance.Results Compared with the control group,the rats in the model group had blood urea nitrogen (28.93 ±3.37) mmol/L,creatinine (162.31 ± 34.08) μmol/L,24 h uric acid (132.67 ± 27.96) μmol,Ca2+ (18.24 ± 1.94) μmol/24 h,the content of malondialdehyde (191.04 ± 20.56) nmol/mgprot in kidney homogenate was significantly increased,blood Ca2+ (2.01 ±0.28) mmol/L,renal GPX (479.82 ± 136.97) μmol/gprot,SOD(1.54 ±0.21) U/mgprot decreased significantly,these differences were statistically significant (P ＜ 0.05).Renal histopathology showed low-dose and high-dose prevention and treatment groups kidney calcium oxalate crystals and kidney damage were less than the model group.Conclusion The extract of Tribulus terrestris has a beneficial effect against calcium oxalate urinary stone formation induced by ethylene glycol.
