4 groups of subjects including 1.590 workers with occupational diseases and exposed to the risks. 175 managers, 153 health workers, 32 officals of the Labor – Invalide – Social services, social insurance in 37 factories in 7 provinces/cities: Thai Nguyen, Quang Ninh, Hanoi, Nam Dinh, Nghe An, Hue and HoChiMinh city, were enrolled into study performed from September 2001 to June 2002. The study had showed a rate of 93.8% exposed subjects underwent regular health examination of low quality. The result table delayed < 2 weeks with the cost of 35.000 VND for each subjects. In > 71.5% of fatories, occupational health examinations were conducted. The prevalence of pneumoconiosis was 94% and the cost of consultation 83.000 VND for each. There was a rather good realization of the regime of health care allowance and subsidy.

In 2.504 blood donors, Abbott Determine test was used to promptly detect HbsAg. By the quick test HbsAg was detected on 7.51% of donors. 25.49% of donors gave their blood though they had knew his infection of HBV. By rapid screening test for HbsAg in the donors, the percentage of cencelling tranfusion reduced from 11.1% to 0.52%. Previous screening by rapid test for HbsAg, it was prevented from using the blood of HBV infected donors. Each year a sum of billion VND was saving for cancelling transfused blood.

There is a conservative region of more than 130 bp long in the mitochondria genome of Leishmania mexicana M379 clone E8, and this it is found across many other Leishmania spp. Based on this notion, a pair of PCR primers were designed to amplify the corresponding regions in the minicircles of many other Leishmania species such as L.major, L.donovani. PCR method can be used to detect protozoa in Vietnam

Study on chemical components of Fissistigma capitatum Merr. ex Li (scientific name was defined by Bachelor Ngo Van Trại, National Institute of Medicinal Materials) collected at Sa Pa in June 2003. 600g of dried and grinded leaves and branches were leached with methanol:water (95:5) at room temperature. Methanol solvent was distilled at decreased pressure. The remained fluid was extracted many times with n-hexane, ethyl acetate and butanol. N-hexane was vacuum-evaporated, which collected 11.2g sediment. N-hexane sediment fluid was refined by silica gel chromatographic, which collected compounds 1 and 2. The structure of compound 1 was taraxerol, compound 2 was 16-hentriacontanone with white crystal form when comparing with document data. This compound named palmitone and previous isolated from the leaf of Annona diversifolia

Lasia spinosa L. (Araceae) has been used in the Vietnamese traditional and folk medicine for treating sore throat, cough, nephritis, rheumatism, liver diseases (hepatitis, ascitic cirrhosis), sequels of malaria and skin diseases. In this primary study on chemical constituents of Lasia spinosa L., leaf powder and root powder of Lasia spinosa L. were leached with n-hexan, CHCl3 and MeOH solvents, three times for each solvent. 5 compounds including p-hydroxy benzaldehyde, acid p-hydroxybenzoic, acid 3-hydroxy-4-methoxy benzoic, 2-(4’- methoxyphenyl)-ethanol, adenine were isolated by spectroscopic methods

The subjects consisted of 15 processing households and 150 processing direct employees. Intervention of “Health promotion at workplaces for processing village households” according to the guide-line of WHO was implemented. The study was firstly carried out in Tien Ngoai food processing village, Khac Niem commune, Bac Ninh province from 2002-2003. The results showed that the intervention was successful. Tien Ngoai village developed its down rule, in which there were regulation on environmental protection, occupational safety. The village also established a fund for these activities. Each household carried out at least 3 improvements of working and living conditions. Commune health station in cooperation with preventive medicine centers organized medical examination and consultation for handicraft employees. Improving awareness of employees on occupational safety and environmental protection were done in different ways.

During 7/1996 - 11/1998, MEDIC - MRI department had studied 4571 patients included 985 cervical spinal cases (22%), infections (03%), degenerative diseases (51%), cervical spinal stenosis (30%), trauma (35%), tumor (06%), miscellaneous lesion (05%). Cervical spinal stenosis has been usually seen. The main etiologies of cervical spinal stenosis include cervical disc herniation, cervical spondylosis, and ossification of the posterior longitudinal ligament. It causes the severe complications such as radiculopathy and chronic myelopathy (tetraplegia, sensory disorder, and bladder dysfunction). The best knowledge of the lesion of the cervical spinal stenosis could facilitate treatment and save the patient life with hope of good motor recovery. The purpose of this study is to determine whether MRI can be used to define the nature of cervical spinal stenosis.

40 patients diagnosed as cholangiome of which 9 patients diagnosed by biliary cell, 13 patients diagnosed by CT scanner, and 18 patients diagnosed by operation. The biliary obstruction in the general hepatic tube occurred in 95% of patients in which the lesion involved in the 2 branches of liver was 75%. The image of cholangiome in the film of cholangiography found that biliary fair stenosid (62,5%).
