RESUMO
Objective To study the effect of ganoderma lucidum polysaccharides on T cell subsets and AQP1, AQP3 expression of bladder cancer T24 cell line bearing mice.Methods 60 BALB/C nude mice were selection as experimental animals, bladder tumor bearing animal models were made by bladder cancer T24 cells subcutaneous injection, and were randomly divided into control group, cisplatin group, ganoderma lucidum polysaccharides and cisplatin group, cisplatin group given 25 mg/kgcisplatin intraperitoneal injection, cisplatin combined ganoderma lucidum polysaccharide group given 200 mg/kg ganoderma lucidum polysaccharide lavage, 25 mg/kg cisplatin intraperitoneal injection, the control group given quite a volume normal saline lavage.Then tumor volume and weight, peripheral blood T cell subsets and AQP1, AQP3, Caspase-3, Bax mRNA content in tumor tissue were determined.Results Cisplatin group, cisplatin combined ganoderma lucidum polysaccharide tumor volume and mass were significantly lower than the control group (P<0.05), cisplatin and ganoderma lucidum polysaccharide tumor volume and mass were significantly lower than that cisplatin group ( P<0.05 ); Cisplatin group, cisplatin combined ganoderma lucidum polysaccharides group CD4 + T cells, CD8 +T cells , CD4 +/CD8 + were significantly higher than that of control group (P<0.05), cisplatin combined ganoderma lucidum polysaccharide group CD4 +T cells, CD4 +/CD8 +were significantly higher than that of cisplatin group (P<0.05); Cisplatin group, cisplatin combined ganoderma lucidum polysaccharide group mices tumor tissues Bax, Caspase 3 mRNA content were significantly lower than the control group (P<0.05), cisplatin combined ganoderma lucidum polysaccharide group Bax,caspase 3 mRNA content were significantly lower than that of cisplatin group (P<0.05); Cisplatin group, cisplatin combined ganoderma lucidum polysaccharide group mice tumor tissue AQP1, AQP3 mRNA content were significantly lower than the control group (P<0.05); Cisplatin combined ganoderma lucidum polysaccharide group AQP1, AQP3 mRNA content were significantly lower than cisplatin group (P<0.05 ). Conclusion ganoderma lucidum polysaccharide can inhibit tumor growth and enhance cellular immune function of bladder cancer T24 cell line bearing mice, and adjust the expression of pro-apoptotic genes, AQP1 and AQP3.
RESUMO
Objective To investigate the role of AQP2 and Na +-K +-ATPase in the pathogenesis of kidney injury with multiple organ dysfunction syndrome,and try to find the express characteristics of them.Methods A total of 72 healthy rats were randomly (random number) divided into two groups:control group (n =24) and Lipopolysaccharide group (n =48).The Lipopolysaccharide group rats were injected with 5 mg/kg lipopolysaccharide at the beginning while the control group was 0.9％ sodium chloride.After the model was succeeded,the rats were put to death at 6 h,12 h,24 h,2 days,3 days and 5 days equally.The urine and blood were collected.Blood were used biochemical tests to check.kidney AQP2 protein and mRNA expression level in the organization were applied the immune organized and RT-PCR technique to detect.Applied kit for determining the content and activity of sodium/potassium-atpase.Results The volume of urine in LPS group decrease quickly at 12 h and 24 h,but increased after 2 days.Urea nitrogen and creatinine increased gradually,and peaked at 48 h,after then gradually decline.AQP2 mRNA and protein expression decreased,and minimize at 48 h.The content of Na+-K+-ATP ase has no obvious difference,but the activity significantly decreased at the beginning,then increased gradually,but it was still lower than the control group.Conclusions In renal injury rats model with multiple organ dysfunction syndrome,AQP2 is the structure of renal reabsorption function,while Na +-K +-ATPase directly involved in or indirectly reflected the state of kidney energy metabolism.Recovery of AQP2 protein and energy metabolism,before the rat kidney function improved.
