Method: Levels of Serum-CRP concentrations were deter-mined in 60 patients with pulmonary tuberculosis, 30 healthy volunteers and patients in follow-up after completion of antitubercular treatment (DOTS therapy). Results: Serum-CRP levels were found to be significantly higher in smear-positive group as compared with the follow-up patients and smear-negative control group. The values were 43.65 ± 23.68, 9.88 ± 5.23 and 4.04 ± 3.85 mg/L respectively (P Conclusion: Serum-CRP levels are significantly correlated with disease severity in patients with active pulmonary tuberculosis. Thus these findings from the present study would certainly add new criteria for early diagnosis of TB, which may lead to development of new strategies to treat TB.展开更多

[Method] A total of 1 200 chickens at the age of 44 weeks were selected and randomly divided into five groups. After administration with different dosages of astragalus polysaccharides and berberine for 9 weeks, serum biochemical indexes were determined and nu- trient contents of egg were detected. [ ltesultl The contents of total protein, globulin, high-density lipoprotein cholesterol （HDL-C） and alkaline phosphatase （ALP） in all treatment groups were significantly （ P 〈 0.05 or 0.01 ） higher than those in the control group. The cholesterol contents of all treatment groups were significantly （ P 〈 0.05 or 0.01 ） lower than those of the control group. E Conclusion~ The optimal concentrations of as- tragalus polysacchaddes and berberine in basic diets are 200 and 30 mg/kg, respectively.展开更多

[ Method] A total of 600 22-week-old commercial Roman laying hens were randomly divided into five groups, with eight repli- cates in each group and 15 hens in each replicate. Group I was taken as the positive control group, and laying hens in group ] were fed with basal diets in anrmal thermal environment. Temperature humidity index of group 1 was between 64.9 and 68.9. Group II was taken as the negative control group, and laying hens in group II were fed with basal diets under heal stress condition. Temperature humidity index of group II was higher than 72. laying hens in groups llI-V were fed with basal diets supplemented with 200,400 and 600 mg/kg betaine under heat stress condition respectively, and temperature humidity indexes in groups III-V were all higher than 72. The experiment lasted for 14 weeks. [ Results ] Results showed that there were no significant differences in average daily feed intake, feed egg ratio and broken egg rate among different test groups （P 〉 0.05 ）. Hen-housed laying rate, hen-housed egg yield, serum total protein （TP） content and serum alkaline phosphatase （AKP） activity in group II were significantly lower than those in group I（ P 〈0.05 ）. However, activities of glutamic-oxalacetic transaminase （GOT）, creatine kinase （CK） and glutamic-pyruvic transaminase （GPT） in group II were significantly higher than those in group i （P 〈0.05 ）. Hen-housed laying rate, hen-housed egg yield and serum TP content in group IV were significantly higher than those in group II（ P 〈 0.05 ）. Hen-housed egg yield, serum TP eontent and serum albumin （ALB） content in group V were significantly higher than those in group II（P 〈0.05）. Activities of serum CK and Girl in groups IV and V were significantly lower than those in group II （ P 〈 0.05 ）, serum triglyceride （TG） content in group V was significantly lower than that in group 11 （ P 〈 0.05 ）. [ Conclusion] Metabolism and physiological function of laying hens could be affected by heat stress, and which caused a decline in performance. Adding of dietary betaine in diets could improve hen-housed egg production and hen-housed laying rate, which could also improve the health of laying hens under heat stress condi- tion. The appropriate dietary adding content of betaine was 400 mg/kg.展开更多
