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)

Intersect description and processing data according to medicine statistics on 30 patients from 12/2003 to 9/2004 at Thong Nhat hospital. Result show that: Making pneumonia bacteria at Thong Nhat hospital are major bacillus (-), pseudomonas aeruginosa (83,3%), Klebsiella pneumonia (43,3%), Staphylococcus aureus (16,7%), Acinetobacter (6,7%). The bacteria is strong resistance to large spectrum antibiotic. There are 4 species of Psedomomas aeruginosa and 1 of Klebsiella pneumonia resist to all antibiotic newly used. Pathogenic multibactera is 60%.

A prospective study on 80 patients over 60 years old who were diagnosed hospital pneumonia at Thong Nhat hospital from December 2003 to April 2005. Results: hospital pneumonia by multi-bacteria was 55%. The common bacteria were K.pneumonia (56.25%); P.aeruginosa (55.0%); Acinetobacter (18.75%) and S.aureus (15%). The resistance level of bacteria caused hospital pneumonia: P.aeruginosa resisted most of antibiotics except Imipenem and Timentin (recently used in hospitals) with sensitive rate of 66.13% and 65%, respectively. K.pneumonia was sensitive only with Imipenem at the rate of 96.55%, Amikacin 66.91%. S.aureus resisted penicilin and most of other antibiotics; it was sensitive only with vancomicin at the rate of 100%. In relapsing or unsuccessful patients, the resistance of bacteria was stronger than the first time isolation.

In this study, 80 hospital acquired pneumonia patients ≥60 years old (59 males, 21 females) were treated in Thong Nhat Hospital of HCM city from December 2003 to April 2005. The results: mortality rate of hospital acquired pneumonia in the elderly patients was high, accounted for 43.75%. Invasive mechanical ventilation, long-term endotracheal intubations, endotracheal reintubation increased risk of death. Multi-organ failure, liver failure, kidney failure, gastrointestinal bleeding, shock, unconsciousness and diabetes increased fatal risk of disease. Serious prognostic factor included: no regress of fever, increase of leukocyte after 10 days of treatment, no improvement of PaO2/FiO2 ratio after 3 days of treatment.

A study was performed to identify a high activity restriction enzyme recognizing 5’-GCGC-3’. Isoschizomer Hhal is a endonucleaza, which has been found in a bacteria isolated from a soil sample picked up in Nghean province. This enzyme has a similar activity with Hha l but it is a other protein of other host bacteria, therefore, it is temporary called a isoschizomer of Hhal. About the enzyme’s specific, Hhal cleaves 5 standard DNA molecules at 384 sites, in which 215 sites at DNA , 103 sites at DNA T7, 18 sites at x174, 31 sites at pBR 322 and 17 sites at pUC 19. Isoschizomer Hhal with high activity, stable met the need of users and laboratory of Vietnam.

A rapid agglutination – inhibition test was realized with hCG-coated sheep erythrocytes and rabbit antibodies to hCG. Determined amount of hCG on the red blood cells and titrated concentration of antibodies allowed the test to be sensitive at 200 UI/l for confirmation of pregnancy at 2-3 weeks (0-5 days following the first missed period). 3.000 tests were implemented in Nha Trang Pasteur Institute and Hanoi Newborn & Mother Protection Hospital showed that confident rate was 99%. The test was then used for diagnosing the urines of women just before their abortion. The results indicated that more than 11% of these women, at less than 15 days following the first their abortion, were not pregnant and should avoid abortion.

An IS 6110 fingerprint analysis of 168 Mycobacterium tuberculosis strains isolated from Vietnamese patients has been performed; 67 strains are isolated in the North (N strains), strains isolated in the South comprise 66 strains from tuberculosis patients without AIDS (S strains) and 35 strains from tuberculosis patients with AIDS (A strains). The number of IS 6110 copies per strain varies from 1 to 22 copies. The population of N strains are different from the population of the overall South strains where there was a high prevalence of strains with more than 15 IS copies. That regional difference between the Vietnamese strains was clearly shown by the fingerprint patterns of strains with more than 6 IS. The populations S strains and the A strains have similar fingerprint patterns and 80% of the South strains belong to one big family. In the contrary, a high polymorphism was seen among the N strains

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).
