16 adult rabbits induced the experimental superficial thermal burn was randomly divided into 2 groups: group I treated by hyperbasic oxygen combining with saline and group II (control) only treated by saline. The bacterial tests implemented after 3,7 and 14 days of the treatment have shown that the hyperbasic oxygen inhibited the common bacteria in the infected burns. In the 14 days, the rate of burns infected S.aureus and P.acruginosa and number of bacterials/1cm2 of burn surface in the group I was less this in group II (control).

The study of hyperbaric oxygen therapy (HBOT) on the full thickness thermal burn wound was done in 24 rabbits. After infliction of the burn wound, the animals were randomized into 2 groups: a HBOT group (n=12) and non-HBOT group (n=12). Studying a change of the burn wound, we found that (1) HBOT had statistically significant effect on anti inflammation (p<0.01). (2) HBOT had statistically significant effect on decrease the time of necrosis separation (p<0.01). HBOT had statistically significant effect on decrease the time of burn wound healing.

The study involved 115 patients who was diagnosed with cervical disc herniation by MRI at the Military Hospital 108 and ViÖt - §øc Hospital from January 1997 to July 2001. Among these, 82 patients underwent cervical discectomy and 33 patients were treated by medication. 15 patients were studied retrospectively, and 100 patients were studied prospectively. Mean age of patients was 49.15 years (ranged from 27 to 78). 93 men, 22 women. The results showed that 1-segment disc herniation was most common (53.9%), followed by 2-segment herniation. 3-segment herniation was seen only in 10 cases. 100% of patients in operative group have post-operative diagnosis as same as MRI diagnosis. 87.5% of patients have excellent and good outcome at 1 week after operation. It was suggested that the diagnosis of cervical disc herniation and operative indication was appropriate.

Participants in this study were 28 patients who were diagnosed with cervical disc herniation by magnetic resonance imaging (MRI) at the Internal Medicine Department of the Military Hospital 108 between July 1997 and July 2001. Mean age of patients was 47.54 years, ranged from 34 to 66. Males: 19, females: 9. It was found that that out of these, 10 patients had 1-segment cervical disc herniation, 15 patients had 2-segment cervical disc herniation, and 3 patients had 3-segment cervical disc herniation. Total of herniated cervical discs was 49 per 28 patients. Good and moderate results of nonoperative management were achieved in 84% of root syndrome sub-group, in 33.3% of myelo-root syndrome sub-group and in 78.57% of total group. Internal management included cervical immobility, analgesics, non-steroid anti-inflammatory drugs, vitamin B, muscle dilation, sedation, cervical block and manipulation, and physiotherapy.

Between November - December 2000, hemoglobin level was measured in members of 9,879 households in 7 ecological regions. Among these, 7,135 households have under 5-year children; 2,744 households have pregnant women. The results showed that the overall rate of anaemia in under 5-year children is 34.1%; this rate in under 2-year children is 50%. The average hemoglobin content is lowest in under 2-year children. Rate of anaemia varies between ecological regions. For women, rate of anaemia is highest in Southern Central Part. For under 5-year children, rate of anaemia is highest in T©y Nguyªn region. This rate is higher in rural than in urban. Other factors related to anaemia are educational level of women, parity, pregnancy and living condition.

A survey on chemical and physical factors was conducted in November 1996. The samples of air, water and dust were analysed at the Institute of Occupational Medicine. Results showed that: the conditions of air ventilation, microclimate, light, noise and air pollution, dust at 7 working places in tunnels of Yaly hydroelectric plant were not compatible with allowed hygienic standards.

The new apparatus is improved on the base of the apparatus for volatile oils determination of the “Methode I” described in the Vietnamese Pharmacopeia I (1971). It includes in 3 principal parts: a shortneck 0.5-1 liter flask, a cold condenser and a tube adapter, which binds the flask and a condenser. Tube florentin, which is suspensed in the tube adapter, is graduated in 2 parts: the superior part to 0.1ml and the inferior part (smaller) to 0.02ml. The improved apparatus is simple, good closed and permit to determine exactly the volatile oils in the drugs.

The formula of the skin cream containing the extracts of Centella asiatica (L.) Urb. and Curcuma longa L. - the two medicinal plants available in Vietnam – was established by means of experimental design and computer – aided optimization. At first, the formulae were designed by varying the amounts of their ingredients such as Polawax, cetostearyl alcohol, Tween 80 and Span. Then, the Oil-in-Water emulsion – type creams were manufactured by using the PUC VIKOSATOR emulsor. Next, the resulted products were evaluated for their physics – chemical parameters including the melting point, the extrudability and the number of the Oil particles. After that, the multiple – objective optimization was performed by the CAD/Chem artificial intelligence software, which is the unification of neural networks, fuzzy logic and genetic algorithms. At the end, the optimized formula was strictly evaluated by both hypothetical tests and experimental trials. In drug quality control, the investigation of skin cream was proven to meet its ointment requirements.

Two samples Amomum from NinhThuan were investigated. They were identified as Amomum thyrsoideum Gagnep. and Amomum longiligulare T.L. Wu. The leaf-oils and fruit-oils from two varitae were analysed by GC/MS. 14 compounds were detected in the leaf-oils and 19 in the fruit-oils. The main components in the leaf-oils, from A. thyrsoideum were cis-Ocimene (39.03%) and -Pinene (41.55%), from A. longiligulare were -Pinene (22.50%) and -Pinene (61.77%). The main components of the fruit-oils were camphor (34.29-35.77% and 44.46%) and bornyl acetate (41.22-43.25%, and 26.62%). The fruits from the two varieties are rich on essential oil. The amount of oil were 3.0-3.75%

Investigatetion of the fruits and leaves oil of Litsea cubeba (Lour.) Pers. wild growing in the moutain areas in Ba Vi district, Ha Tay province. The major components of the fruits oil of Litsea cubeba (Lour.) Pers. is citral, which includes of neral (citral b) and geranial (citral a) with content over 65% equivalent in some Northern provinces. Fruits and leaves oil analysis were carried out by a combination of capilarry GC and MS. The main components of the leaves oil are linalol (over 85%), 1.8-cineol (-50%), sabinen (10-15%) and -terpineol or -terpinyl acetate (10-20%). This plant in Ba Vi has many biochemical diversification, that is also a character of Lauraceae as Long nao, Vu huong.
