Coptosapelta tomentosa (Blume) Vahl. ex Heyne var. dongnaiense (Pit.) Phamh. Rubiaceae, found in the rain forest areas of the central part of Vietnam, has been used in folk medicine for treatment of rheumatism or washing wounds to prevent infection. There has been no report on the pharmacognostical characteristics and pharmacological activities of this plant, up to now. In this report, morphological, and microscopic characteristics, determination of ash and extractable matter were examined; qualitative and quantitative analysis of chemical constituents of this plant were investigated. Saponins, triterpenes, coumarins were found as the main components of all roots, stems and leaves. Anthraquinones and flavonoids, however, were only found in the roots. The amounts of total saponins and anthraquinones in stems and roots were also estimated

Study on 274 non-pregnant women with melasma at the age of 15-67, treated in Hanoi Dermatology Hospital from November 2001 to October 2004. The results: melasma was a common disease in all of age of woman, but it accounted for 86.49% in 25-55 years old group. Melasma with localized lesions in epithelium accounted for high percentage (58.03%) then mixed lesions (20.2%). The lesions occurred in both 2 cheeks among 50.73% of worker and farmer patients. 6.56% of patients with pigment disorder skin disease, 26.64% patients with chronic disease, 19.7% of patients had related factors such as spontaneous abortion, abortion or taking contraceptive pills, 9.72% of patients had endocrine diseases

The cerebrovacular malformation mainly comprised arteriovenous fistula and cerebral aneurysm and usually occurred clinically stroke due to the bleeding, vascular rupture or aneurysm rupture. There were numerous patients with cerebrovascular malformation that undiagnosed because of no bleeding or unhospitalization. It was remain controversial problem that it should where be early operated or not to prevent from vasoconstriction.

An interview of 1950 persons who worked at 37 companies in 7 localities that has high risks of working accidents and occupational disease. Results have shown that the document system was relatively complete to contribute importantly to the health care, detection of occupational disease- and implementation of regime related with working people. The implementation of regulations of working protection for working people suffered the occupational disease was quite well: 86,3% of companies considered in the health care and periodical consultation. The ways of reduction of dust have not properly been considered. Most of working people knew the risk of pulmonary dust, bronchitis and occupational deaf

1667 laborers were interviewed on using the plant protective chemicals in 16 communes of 8 provinces: §ång Nai, L©m §ång, TiÒn Giang, B×nh D­¬ng, B×nh Ph­íc, Ninh ThuËn, B×nh ThuËn, Kh¸nh Hßa in year 2000. Results: 100% or farm households were using plant protective chemicals. Number and types of plant protective chemicals used are various. The management of plant protective chemicals remained to be not tightly. They are used unsafe and inappropriately, cause effects on the laborer health and toxicity. The incidence of Tb toxicosis is 22.92 per 10,000 people. The incidence of Padan toxicosis is highest.

17 wild-type measles strains were isolated from both sporadic cases and 4 outbreaks in the Northern, Centre, and Highland areas of Vietnam in 2000-2002. The sequence analysis of 450 nucleotides of the most variable COOH- terminus of N gene showed that established in the year 2000 with the representative of MVi/Beijing.CHI/9411, genotype H2 (Clade H) continued circulating in the North and Highland of Vietnam. This study also revealed that wild-type measles strains circulating in the Center fell into genotype HI (Clade H) with the representative of MVi/Hunan.CHI/93. It was the first time that genotype HI was discovered In Vietnam. The difference within each genotype is bigger, nevertheless, no more than 3.0% at nucleotide level. The wild-type strain isolated in Lai Chau belonging to genotype D5 (Clade D) has imported into Vietnam from Thailand was under consideration.

Neem Leaves (Azadirachta indica A. Juss) collected in Binh Thuan province in May have been shown to contain alkaloids (0.66%), flavonoids (2.95), coumarins, reduced sugars and lipids. The alkaloid fraction gave 6 spots and the flavonoid fraction yielded 7 spots on this layer chromatography. Two substances, i.e., A6, an alkaloid and a flavonoid suspected to be Azadirachin A, have been isolated for further study. Liquid extract of Neem Leaves exerted anti-microbial activity against Staphylococcus aureus, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and candida albicans

30 patients with check sunburn, aged 18-60 years old treated by hydroquinone 2% in combining with sun protected cream. After 6 moths pigment reduced by 45,6%, mean size of lesion reduced by 78%. 90- 100% of patients had the size of lesion reduced by 13,4% and 61% of patients had the size of lesion reduced by 70-89%.
