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%).

The solid dispersion system (SDA) of dihydroartemisinine (DHA) with PEG 400, PEG 1540, PEG 4000, PEG 6000 and Tween 20, cremophor EL, PEG 400 stearate as cocarrier were prepared. the experimental results showed that the release rate of DHA from suppository base was greater than the semi-synthetic triglyceride base and the physico-mixture

400 workers in 4 coalmines were investigated, on the medical records, physical and laboratorial examinations. Working environment was studied. The common diseases observed are silicopneumoconiosis (5.82%) and mycodermatitis (64.69%).

23 patients with mitral stenosid with or without mild mitral open, ages of 23-50 (male: 10) received an operation. As the results of direct measurement of pulmonary arterial pressure and left atrial pressure in an operation have shown that the pulmonary arterial pressure was direct correlated before and after operation(r= 0.572 before operation; r=0.65 after operation).These parameters were reduced significantly and rapidly after operation when comparing with these before operation.

WHO and MOH collaborated to develop a pilot project on 'Health Promotion at Workplaces in SSEs and MSEs'. This project aimed to improve workers' health, helping them to protect health themselves increasing productivity and income; as a result it brings benefits to both enterprises and workers. This report presents the results that have been implemented in Hai Phong and Hue City and improvements of this model that can be applied in other places.

23 patients (10 males, 13 females) with mitral stenosis aged from 23-50 years of old (mean 37.5 years) were enrolled in the study. Valvular opening area ranged from 0.7cm2 to 1.2cm2. 5 patients have mitral stenosis alone. 18 patients have mitral stenosis with insufficiency grade I, II. 14 patients have sinus rhythm and 98 patients have atrial fibrillation. Pulmonary artery pressure ranged 25mmHg to 45mmHg when measuring directly. There was closed positive correlation between pulmonary artery pressure and right ventricular pressure with r= 0.509 for pre-operation and 0.548 for post-operation. After valve detachment, both pulmonary artery pressure and right ventricular pressure decreased rapidly and dramatically in comparison with prior detachment with p = 0.01.

A study was carried out on the 23 patients (male:10, female: 13) with the mitral stenosid with merely close or combination with the mild mitral open (grade III), ages of 23-50 indicated an operation for seperation of close valve in the Army Central hospital 108 during 1/1998 to 10/1999 in which there were 5 patients with the mitral stenosid, 18 patients with the mitral stenosid in combination with the mitral open grade I, II, 14 patients with the atrial rhythm, 9 patients with atrial fibrillation. The atrial pressure reduced from 15-67 mmHg to 15-45 mmHg. There was a direct proportional between the left atrial and right ventricular pressures

A new minicircle in the mitochondria genome of Leishmania mexicana M379, clone E8 was monitored using different methods as PFGE, hybridization,... The 0,7-kb of the circle was cloned and analysed. It appears to have a Chi-like octomer in the region of replication
