RESUMO
OBJECTIVE: To establish a New Zealand rabbit model of acute kidney injury induced by cisplatin. METHODS: A total of 24 male New Zealand rabbits were randomly divided into control group,low-,medium-and high-dose cisplatin group according to the body mass. Rabbits were injected with cisplatin at 0. 0,1. 0,2. 0,4. 0 mg/kg body weight by auricular vein. Rabbits in low-dose group was continuously injected for 5 days,medium-dose group was continuously injected for 3 days,and the high-dose group was injected for once per day. Rabbits in the control group did not receive any treatment. Blood was collected from the middle ear artery and 24 h urine was taken before exposure and on day 1,day 3,day 5 and day 7 of injection. The serum creatinine( Scr) and urea nitrogen( BUN) were detected by colorimetric method,and 24 h urine kidney injury molecule 1( KIM-1) was measured by enzyme-linked immunosorbent assay. Plasma platinum,24 h urinary platinum and renal platinum level were detected by inductively coupled plasma mass spectrometry.At the end of the experiment,rabbits were sacrificed and the left kidney was taken for histopathological examination.RESULTS: The body mass of rabbits of the low-,medium-and high-dose groups on day 7 after cisplatin exposure was lower than that of the control group( P < 0. 05),and lower than that of the same group before exposure( P < 0. 05). After 3 days of exposure,the Scr level in each dose group was higher than that of the control group( P < 0. 05),the Scr level on day 3and day 5 in medium-and high-dose groups were higher than that of the low-dose group( P < 0. 05). The BUN levels on day 3 and day 5 in medium-and high-dose group were higher than that of the control group and low-dose group( P <0. 05),the BUN levels on day 7 in three dose groups were higher than that of the control group( P < 0. 05). The levels of plasma platinum and 24 h urinary platinum in the three doses groups of New Zealand rabbits on day 1,day 3,day 5 and day 7 after exposure were higher than that of the control group( P < 0. 05),and were higher than the pre-treatment levels of the same group( P < 0. 05). The level of 24 h urinary KIM-1 in the meclium-dose group of New Zealand rabbits was higher than that of the control group on day 3 of exposure( P < 0. 05). The level of 24 h urinary KIM-1 in the mediumdose group of New Zealand rabbits on the 5th day after exposure was higher than that of the control group( P < 0. 05). The renal platinum levels in the three groups of New Zealand rabbits were higher than that in the control group( P < 0. 05).The pathological changes of rabbit kidney caused by cisplatin are mainly tubular dilatation,protein cast,alkalophilic and interstitial nephritis. CONCLUSION: Cisplatin can induce acute kidney injury in rabbits,and the degree of injury is dosedependent. The dose of 1. 0 mg/kg body weight continuous injection for 5 days is closely related to clinical use of cisplatin,which is recommended for model establishment.
RESUMO
OBJECTIVE: To explore different doses of sodium(s)-2-(dithiocarboxylato((2R,3R,4R,5R,6R)-2,3,4,5,6-pentahydroxyhexyl) amino)-4-(methylthio) butanoate(GMDTC) for removing cadmium. METHODS: Thirty-five male New Zealand rabbits were randomly divided into blank control group,GMDTC high dose control group,model control group,ethylene diamine tetraacetic acid(EDTA) control group and GMDTC low,medium and high dose groups,five rabbits in each group. The blank control group and GMDTC high dose control group were given 0. 90% normal saline solution intravenously; model control group,EDTA control group and GMDTC low,medium and high dose group were given 2 μmol/kg of cadmium chloride(CdCl_2) and 40 μmol/kg of β-mercaptoethanol mixed solution intravenously,5. 0mL/kg body weight(bw),once a day for five days. On the forty-one day of the experiment(the fist day of GMDTC treatment),the control group and the model control group were injected 0. 90% normal saline solution 250 mL via ear vein,the EDTA control group was given EDTA solution at the dose of 93. 5 mg/kg bw with 250 mL 0. 90% normal saline solution,also via ear vein; the GMDTC high dose control group,and the GMDTC low,medium and high dose groups were given 250 mL GMDTC solution at the concentration of 108.0,12.0,36.0 and 108. 0 mg/kg bw with 0. 90% normal saline by intravenous infusion,once a day,6 times a week for four consecutive weeks. The urine β_2-microglobulin(MG),renal cadmium,blood cadmium,and urinary cadmium before and after the treatment were detected. RESULTS: The body weight of New Zealand rabbits increased with the increasing feed time(P < 0. 01). The levels of β_2-MG before treatment increased in model control group,EDTA control group,GMDTC low,medium and high dose groups than that in the blank control group(P < 0. 01). The levels of renal cadmium after treatment in GMDTC medium and high dose groups decreased compared with those in the blank control group and EDTA control group respectively(P < 0. 05). The blood cadmium after treatment in EDTA control group,GMDTC low,medium and high dose groups were decreased compared with those before treatment in the same group respectively(P < 0. 05),meanwhile decreased than the blood cadmium after treatment in the model control group respectively(P < 0. 05). The blood cadmium after treatment had not a statistically significant difference among the EDTA control group,GMDTC medium and high dose groups(P < 0. 05). At all the time points(1,6,8,13,15,20,22 and 28 days after treatment),the urinary cadmium after treatment in EDTA control group and the three GMDTC dose groups increased compared to the model control group at the same time(P < 0. 05). The urinary cadmium after treatment increased with GMDTC dose increased at the other six time points,expect on 20 and 22 days after treatment(P < 0. 05). The blood cadmium removal rates after treatment were 70. 06%,74. 86% and 78. 05% and the renal cadmium removal rates were 14. 27%,27. 95% and 61. 24% in GMDTC low,medium and high dose groups,respectively. CONCLUSION: The intravenous infusion of GMDTC at the dose of 108. 0 mg/kg bw effectively removed cadmium in cadmium poisoning rabbit. This dose had no obvious toxic effect and was equivalent to human dose of 36. 0mg/kg bw which meets the requirement of new drug property.

Objective To investigate early diagnosis and treatment of tumor of duodenal papilla.Methods Their clinical data of 64 cases of tumor of duodenal papilla confirmed by operation and pathology were analyzed retrospectively.They included 60 cases of carcinoma of duodenal papilla and 4 cases of adenoma.Results The main clinical symptoms were jaundice(42 cases),digestive tract symptoms(35 cases),recurrent cholangitis(7 cases) and hemorrhage of upper digestive tract(1 case).The diagnosis rate accuracy of ERCP,Fiberoptic duodenoendoscopy,MRCP,BUS and CT were 100%,97.3%,82.4%,82.8% and 76.1% respectively.Fifly-five cases underwent pancreatoduodenectomy,5 cases received local resection,and the remaining 4 cases were treated by palliative surgery.The surgical complication rate was 16.1% and the surgical mortality rate was 3.6%.The 1-year,3-year and 5-year survival rate of pancreatoduodenectomy were 67.4%,40.6% and 36.3%.Conclusions Jaundice and abdommal pain are the main symptoms of tumor of duodenal papilla.Fiberoptic duodenoendoscopy and ERCP are most effective methods for diagnosis of tumor of duodenal papilla.It is essential to early select radical resection operation so as to improve the results of surgical treatment.
RESUMO
Urokinase-type plasminogen activator plays an important role in the dissolution of clot and the treatment of thrombosis diseases. Presently, more attention has been paid to urokinase metabolism in human body and the relationship between urokinase fibrolysis effect and its receptor in endothelial cell.Cultured endothelial cell was used in the experiment to react with labelled urokinase in the presence or absence of unlabelled urokinase. It was found that the specific bindind of labelled urokinase with endothelial cell increased with the increasing concentration of labelled urokinase and reached the saturation point from 10 to 32 ?g labelled urokinase/ ml. The maximal binding sites with urokinase per cell were 1.4?10?, and Kd value 7.5? 10~(-12)M, Meanwhile, PMA-treated endothelial cell was used to react with ~(125)I-uPA at the same conditions as discribed above. Compared with the specific binding of DMSO-treated endothelial ceil, the maximal binding sites per PMA-treated cell increased from 1.4?10~6 Per untreated cell to 2.2?10~6, and the Kd value from 7.5?10~(-12)M to 9?10~(-12)M.These results showed that urokinase receptor exists on the surface of endothelial cell, and that the number of receptor per cell could be modulated by PMA. It is possible that the urokinase binding with endothelial cell can play an important role in the very short half-life of urokinase in human body.
