Medical biotechnology is technical solutions using biological properties of cells and of biological moleculars for diagnosis, treatment and prophylaxis. Considerable achievements were gained in Vietnam despite it was applied lately and the investment in medical biotechnology is lower. These achievements include early detection and diagnosis of genes causing cancers like throat-nose cancer, liver cancer, some bacterial and viral infections, some hereditary diseases, bio-products for treatment like anti-rabies serum, anti-venom serum, and vaccines for diphtheria, pertussis, tentanus, hepatitis B, hepatitis A (Havax), Japanese encephalitis, polio and typhoid.

The first study on chemical constituents and biological activities of Clausena lansium (Lour.) Skeels (Rutaceae) growing in Vietnam has been done. Phytochemical investigation of n-hexane extract led to the isolation of five compounds: dihydroindicolactone (1), 8-geranyloxy psoralen (2), imperatorin (3), heraclenol (4) and indicolactone (5), in which this is the first report on the presence of dihydroindicolactone (1). Their structures were elucidated based on LC/MS/NMR hyphenated techniques as well as comparison with those of literature data. The n-hexane extract and its subfractions, ethanol 95% extract and several isolated compounds were evaluated for antifungal activity.

The study on Holarrhena antidysenterica Wall was carried out in Chi Linh (Hai Duong province) in September 2004. Leaves of Holarrhena antidysenterica Wall were collected, dried, grilled to powder, then extracted and isolated flavonoid. Two flavonoids were isolated, on the base of m.p, UV, IR, MS, 1H-NMR, 13C-NMR, DEPT analyses, they were identified as Kaempferol and Quercetin. This is the first time the flavonoids were reported as a substance isolated from Holarrhena antidysenterica Wall in Vietnam

2688 primary school pupils and sencondary school children in the whole of the country, aged 6-11 years old, living in mountain, plain, central and northern areas, southern. A high prevalence of gingivitis inflammation of 42,7- 71,4% was concluded in all age groups, higher in rural area than in urban and increasing with the age. There fore the programme of dental oral care for school children in the whole of country, including oral hygiene education must be promoted.

1412 inpatient cases of the Department of Occupational diseases at Thanh Nhan Hospital in 1997-1999 year period showed an increasing tendency of the incidence of occupational diseases from 22.09% in the year 1997, to 29.5% in 1998 and 47.96% in 1999. The most common diseases were pneumoconiosis 17.35%; occupational bronchitis 10.34%; occupational saturnism 3.88%. The incidence was more in male than in female, and increased with the age. Patients were admitted in all months of the year but with the highest frequency from April to August. 70.75% of the patient were exposed to harmful enviroment, especially with silica dust - 36.53%, then the dust of cotton, wool, chemicals, lead and noise.

84,4% of children aged 6-8 years old sulfered from caries of milk tooth. In average, each subject of thin aged had got 5,07 milk teeth experienced by caries and 12,98 tooth surfaces were destroyed by caries. The incidence of this dental condition was different from geographic areas. In south coast area in Central Viet Nam and MeKong delta, the incidence was higher than other areas and higher than 90% and a very low percentage was treated, almost no significance, especially in North mountain area, north coast and south coast of Central Viet Nam central Highland.

Study on 7955 people (3755 men, 4210 women) in Ha Noi city, Nam Ha, Hai Hung, Ha Bac and Ha Tay provinces and students of Ha Noi Medical College, Ha Noi Teacher's Collage and Ha Noi Agricultural Collage. The period of collecting data was 5 years from 1992 to 1997. In all age groups of two sexes, the circle of right legs were bigger than that in left legs. The circle of right legs had closely correlation and direct propertional with the lean mass of the body in all age groups of two sexes. The values of Pignet-C.T in two sexes had different within 3 first age groups which were significantly. On the math and reality study showed that: Pignet-C.T is the physical estimated index more exactly than Pignet.
