To study the effect of soybean isoflavone on liver oxidative stress resulting from 60Co-gamma rays. Methods: Totally 80 normal female Kunming mice were evenly randomized into 5 groups according to body weight: 3 intervention groups, single irradiation group and normal control group. The normal group and single irradiation groups were given 0.5% CMC-Na, and the 3 intervention groups were given different doses of soybean isoflavone (50 mg/kg, 100 mg/kg, 400 mg/kg) respectively for 14 d. The whole body of single irradiation group and intervention groups were subjected to 4.56 Gy 60Co-γ radiation once on the 7th day, and then the mice were killed on the 2nd day and the 7th day after radiation. Results: The CAT activity of liver tissue of 100,400 mg/kg intervention groups and 3 SI groups were significantly increased on the 2nd day and 7th day after irradiation(P<0.05), respectively; the GSH-Px activity of 100 mg/kg SI group was significantly increased(P<0.05) on the 7th day after irradiation; the T-SOD activity of 50 mg/kg SI group was significantly decreased (P<0.05) on the 2nd day after irradiation,while no difference was observed among remaining groups. The MDA content of 100 mg/kg group was significantly decreased on the 7th day after radiation compared with control group, and MDA content of each group subjected to irradiation were increased on the 2nd day after irradiation,but 3 SI groups nearly decreased to normal level on the 7th day after irradiation. Conclusion: The soybean isoflavone can enhance the antioxidant capability of mice, but it does not show a dose-effect relationship.

Objective:To observe the protective effect of tremella polysaccharides (TP) on mouse aging model induced by D-galactose. Methods: Forty male ICR mice were divided into 5 groups (Group A: treated with 800 mg/kg TP; Group B: treated by 400 mg/kg TP; Group C: treated by 200 mg/kg TP; Group D: aging control; Group E: normal control). Except for Group E,other groups were injected with D-galactose [120 mg/(kg?d)] for 60 d to establish subacute aging model. Group A,B and C were treated with 800,400 and 200 mg/kg TP respectively via intragastric (i.g.) administration. Sixty days later,the spleen,heart, kidney and brain were collected to determine MDA, LP, SOD, GSH-Px and contents of hydroxyproline by colorimetry. Expression of P21 in the kidney were detected by immunohischemical technique. Proliferation and transformation of spleen lymphocytes induced by ConA were determined by MTT method. Results: Antioxidants SOD and GSH-Px activity of TP treated groups were higher than aging control group (P

Objective To evaluate the nutritional status of morbid obesity (MO) before and after laparoscopic adjustable gastric banding (LAGB), and the safety of LAGB.Methods LAGB was performed in 15 cases from Jun.2003 to Nov.2003.Patients′ nutritional parameters were determined before and 1, 3 and 6 months postoperatively.Results There was a significant reduction of weight and body mass index (BMI) ( P 0.05).Conclusion No major nutritional deficiencies were found following LAGB.It is an effective and safe procedure for the treatment of morbid obesity.

In the present study the nutritional status in 1723 inpatients were evaluated. The over nutrition in male, in the cadre, and in patients with cerebrooardiovascular diseases or with diabetes was significantly higher than that in female, in the staff members, and the patient changing the valve in heart with rheumatism, respectively. The over nutrition in patients with breast and colonrectal cancer was obviously higher than that in stomach carcinoma patients. The sum total of lymphocytes was reduced in middle malnutrition patients. The nutritional status was well compared with the abnormal ratio of hemoglobin and serum protein, and A/G reverse was increased in some middle malnutrition patients. The MAC, MAMC and TSF in all of the malnutrition patients were than that of 80% standarized value, and were all the same in the evaluation of body weight.

Objective: To confirm therapeutical effect of Yinlu jiangzhi capsule on experimental hyperlipemia in SD rats. Methods: Animal model of SD rats with experimental hyperlipemia were given different dosages of Yinlu jiangzhi capsule, and the changes of serum lipid concentrations were observed after drug treatment. Results:Using different dosages of Yinlu jiangzhi capsule, there were marked difference between serum lipid concentrations in experimental groups and that of control group. Conclusion:The results suggest that Yinlu jiangzhi capsule has obvious therapeutic effects on the experimental hyperlipemia in SD rats. [
