This cross-sectional study involved 339 students aged 12-15 at 2 boarding schools in Sapa and Yen Binh, determined height, weight, and BMI. Results: there weren’t significant differences between the weights (Sapa’s students: 34.38 kg, and Yen Binh’s students: 33.31 kg), and the average heights of students in 2 regions (p>0.05); but BMI of Sapa’s students is higher than Yen Binh’s students (17.04 vs 16.38, p<0.05)

This cross-sectional study involved 339 students aged 12-15 at Sapa and Yen Binh regions. It measured and compared indexes such as vital capacity (VC), forced expiratory volume 1 (FEV1), and Tiffeneau index. Results: there weren’t significant differences between VC, FEV1 and Tiffeneau indexes of students in both sexes of 2 regions (p<0.05). There is a close correlation between VC and height of student (r>0.9), and between FEV1 and height (r>0.9)

A hemotasis study of 93 cases of arteriosclerosis in Vietnames patients showed: -A hemorrhage tendency of extrinsic pathway abnormalities. -A thrombotic tendency by increasing fibrinogen, factor VII,factor VIII. The C reactive protein (CRP), specific for inflammatory process can be used for evaluation of physiopathology and plaque evolution.

A study on the combination of treatment and traditional Qi training for 65 patients with bronchial asthma in the National hospital of traditional medicine in 1992 has shown that the number of colony of the lymphocyte B,T, T-CD 8 after Qi training were a statistical insignificant different from this before Qi training (p= 0.05) the number of colony of the lymphocyte T- CD4 were reduced a statistical significant from this before QI training (p= 0.05). This indicated the correlation with the extend of obstruction of ventilation. The rate of T- CD4 and T-CD8 after Qi training was a statistical significant different from this before Qi training (p= 0.05).

Anthocyanins are naturally occuring phytochemicals and the main components of the coloring of plants, flowers and fruits. They are known to elicit antioxidative, anti-inflammatory and cancer preventive activity. In this study, we investigated anthocyanins in black / yellow soybean seedcoats using different methods of detection - thin layer chromatography (TLC), capillary zone electrophoresis (CZE) and HPLC analysis. The anthocyanins in soybean seedcoats were extracted by five independent methods of extraction and the aglycons (anthocyanidins) of the corresponding anthocyanins were prepared by acid mediated hydrolysis. The anthocyanin / anthocyanidin in black soybean seedcoat showed characteristic TLC mobility, CZE electrophoretic retention and HPLC migration time while little of anthocyanins were detected from yellow soybean seedcoat. The extracted anthocyanins showed pH dependent retention time in CZE and spectral change in UV-Vis spectrum. HPLC analysis of the hydrolyzed extract of black soybean seedcoat identified the presence of four anthocyanidins. The major anthocyanin in black soybean seedcoat was cyanin (cyanidin-3-O-glucoside), with the relative order of anthocyanidin in cyanidin > delphinidin > petunidin > pelargonidin.

Background: With the help of Japan, the Center for Research and Production of vaccines and biologicals, Hanoi has received a WHO standard measles vaccine production technology, including techniques in the examination of vaccine quality. Therefore, it is needed to be initiative on production of measles antibody. Objective: Study on production of measles antibody in rabbits and selecting the appropriate antibody for production of high titre antibody, which meets the standard of vaccine quality control in Vietnam. Subject and methods: Using the measles antigen from Edmonston and AIK-C strains, which were provided by the Kitasato Institute, to produce measles antibody. Making immunoreaction in rabbits and determination of neutralization antibody titre. Results and Conclusion: Measles antigen of Edmonston Vero 7/P2 strain used in the production of measles antibody in rabbit created the highest antibody titre in comparison with AIK-C strain from vero cell and FL cell supplied by the Kitasato Institute of Japan. Antibody titre of Edmonston Vero 7/P2 strain reached up to 1/8192 and met the sera standard required for measles vaccine quality control, it is similar to the measles sera to be produced from the Kitasato Institute.
