The serology epidemiological investigation on 2-10 years old children in 3 geographic areas of Thanh Hoa province after immunized by oral OPV vaccine showed a rate of protective antibody of 76.5% to all 3 types. There is no difference in the rate of children having protective antibody to type 1 and 2 but type 3 in these 3 areas. A difference of GMT among children in 3 geographic areas, and the last level is in Yen Dinh district. GMT to each polio virus type was higher than the protective immunity level (>8)

Adult made IRC white mouse of 21 week age, weighing 22-25 g underwent an operation for removing the liver, which was washed with PBS buffer. Total ARN extracted from clean mouse liver composes of 3 characteristic band 28S, 18S and 5S. Total ARN concentration received was 10Ug/Ul approximatively. Received PCR product is a characteristic band of the size of some 630bp corresponded to the size of mFGF-21. It is a total gene of mFGF-21 with a sequence 100% corresponding to the registered sequence in the gene international data Bank Number NM-020013

A horizontal section descriptive study was conducted from September 2001 to May 2002 on the subjects who never been vaccinated previously. The examinations for HBsAg and antiHBs were performed by ELISA technique on ASXYM apparatus before the vaccination. Most of 1841 choosen subjects were of aged 15-19, 20-29 and 30-39 groups. The rate of protected subjects was 35.8%, the least was in the aged group of 10-14. These rates were similar in 2 genders

By modern epidemiology and sociology method, 1200 households in the districts of Dong Da, Thanh Tri, Tu Liem in Hanoi city were studied. Environment is not polluted with NO2, SO2, CO, CO2, but with high dust level and noisiness. NO2, NH3 indices in water are within standard level. Concerning the microorganisms Welchii index was high in living water. The pollution with worm eggs was considerable because all examined soil samples had worm eggs. In adult, the most morbidities were high blood pressure, bronchitis, ENT diseases, gastroenteritis; in children, the most were malnutrition, acute inflammations of respiratory tract

60 subjects with brain lacunar infarction and 60 with other brain (no lacunar) infarction aged 20-67 were investigated in Bach Mai Hospital from Jan 2001 to Jun 2002. The proportion of brain lacunar infarction vs other brain infarction was 38% in the same duration. 5 main syndromes of lacunar infarction were 98%, other syndromes 2%. There is no difference in age and gender of both groups. Risk of complications of brain lacunar infarction raised by 8,9 times in comparing with high blood pressure, 6,5 times with smoking, 2,3 times with diabetes

124 pregnant women were examined and monitored at the Military Hospital No 103. The incidence of real physiological and anemia was 75.8% (among them real anemia is 35.5%). IL-6 level in the group with anemic pregnant women was higher than in the group without anemia. There is a negative correlation betweeb IL-6 concentration and Hb level with a coefficient r = -0.8. Low Hb level in anemic pregnant women was often associated with IL-6 increasing phenomenon, when Hb level increased, IL-6 concentration deseased
