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

Treatment for 30 patients with melasma according to standard of Zaumseil, Klaus-Graupe by bleaching hydroquinon in combination with retinoid acid and sun cream. After 6 months, the result showed that: reduced 70% pigment of injury. Size of average injury reduce 87,1% after treatment. In 16,7% patients, the size reduce 90-100% and in 70%, the size reduce 70-89% after treatment.

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.

The dried yeast- bioselen containing 500g selenium/g was used in this study. Rabbits received yeast solution containing selenium with doses of 20 and 40g/kg b.w. per os daily in a course of 30 days consecutive. The experimental results showed that this solution containing selenium did not change significantly common status, the bodyweight and blood forming functions in comparison with control group which received the solvent only

More than 300 patients with palmar hyperhydrosis had been treated by classical upper thoracic sympathectomy at the Department of Neurosurgery in Viet Duc hospital. From 5/1977 to 1/1999, 600 patients were treated by a new technique: a bilateral percutaneous injection of boiling saline into the paravertebral areas containing the upper sympathetic ganglia. An objective reliable criterion of the success of the procedure is arterial criterion of the success of the procedure is arterial vasodilatation in the upper limb, evidenced by pre and postoperative DOPPLER effects and accompanied by dryness of the hands. Good results were obtained in 71% of the patients, bad results in 18% and relapse in 11%. Two major complications were Horner’s syndrome and compensatory hyperhydrosis. The results show that non-surgical sympathectomy has nearly the same results than that of open sympathectomy, with the advantages of greater simplicity and lower cost.
