ABSTRACT
Objective To investigate the positive rates of HBsAg and abnormal rates of Alanine aminotransferase among high school graduates in Jingjiang city.Methods HBsAg were detected by ELISA and ALT was detected by rate assay among 20 988 high school graduates during 2004—2007 in Jingjiang city.Results The HBsAg positive students were 1754.The total positive rate of HBsAg was 8.36%.The positive rate of HBsAg of male(9.46%)was higher than that of female(6.95%).The HBsAg positive rate of rural students(9.44%)was higher than that of urban students(7.28%).HBsAg positive rates of urban students showed a decreasing trend during 2004—2007,the rates were 9.31%,8.08%,6.74% and 5.24%,respectively(P0.05).There were 155 cases(8.4%)with increased ALT among 1754 HBsAg positive students.Conclusion The total positive rate of HBsAg among high school graduates in Jingjiang city from 2004—2007 was 8.36%.The HBsAg positive rate of male students was higher than that of female.The HBsAg positive rate of rural students was higher than that of urban students.8.4% students were found ALT abnormal.We should intensify Hepatitis B vaccine in time to prevent the spreading of HBV.
ABSTRACT
The antimalarial effects of 24 chemical compounds on Plasmodium yoelii in mice and on Plasmodium falciparum in culture were observed . The results from both tests for most compounds are parallel or comparable, except few compounds such as Hydroxyurea and Lincomycin.What suitable methods may be used for preliminary screening of antimalarials are discussed.
