This is a cross sectional study, including quantitative (household survey) and qualitative methods (indept- interview) on 699 people of 157 household living at Cau Giay district. Findings reveal that few people used medical care at the centers (4.3%), the self-medicated rate was highest (42.3%), then the rate of using private services: 27.7% and using services of higher referral levels: 16.7%... Quality and favorable of services, and level of illness... had major influenced to the choices of healthcare services

This study was carried out on 44 patients with celebrovascular accident (CVA) at Huu Nghi Hospital. Results showed that CVA infarctus particularly happens in the rest time much more than in working time (66.0%). 86.6% of the patients had been started to rehabilitation is less than 10 days after CVA. Average distance of the time from CVA to: help to sit up: 4.59 days, one's self sit up: 8.29 days, help to stand up: 9.55 days, one's self stand up: 10.5 days, help to walk: 10.87 days, one's self walk: 13.26 days

Study on 41 pharmaceutical companies in Hanoi city from March 1999 to February 2000. The results: there was an average of 46 pharmaceutical companies of sixteen countries bought the biding documents and about 43% of those companies submitted the bid documents. At each International Competitive Bids, the average of prices of pharmaceutical drugs were correlative with that announced by UNICEF, however, there was still a case of the mean prices of pharmaceutical drugs were higher than that announced by UNICEF. The prices of pharmaceutical drugs were considered lowest, lower than the average of prices of similar products, which were imported into the Vietnam market and announced by UNICEF

Studying the effectiveness of irradiation on bone-marrow, the numbers of leukocyte, erythrocyte, hemoglobin of mice (25 normal mice and 35 mice treated by gamma irradiation with the dose of 600 rad/(100rad/day) (60 Co) showed that: Gamma irradiation reduced total of leucocytes, the number of different leucocytic (lymphocyte, granulocyte, mono and natural killer cells), the ratio of reticulocyte, number of mature erythrocyte and hemoglobin: Total of leucocytes (3,14 ± 1,58 in comparison with 13,45 ± 4,6); monocytes (0,05 ± 0,03 in comparison with 0,26 ± 0,13), lymphocytes (1,66 ± 0,36 in comparison with 6,34 ± 2,84). After gamma irradiation, the number of reticulocyte was 55%, mature erythrocyte was 73% and hemoglobin was 82%

Study on white mices with age of 6-8 weeks, 18-20g body weight. They were divided into 3 groups: group 1 (control group): 30 mices; group 2: mices were immunesuppressed by 200mg cyclophosphamid per one kilogram of body weight, being checked after 5 days of injection; and 300mg cyclophosphamid per one kilogram (200mg on the first day and 100mg on the fifth day) and it was checked after 10 days of injection (group 3). The results: immunesuppressed model implemented by intraperitonial injection of 200mg per one kilogram of body weight checked after 5 days of injeciton. These parameters were used to assign the immune function

Heterogenous transplantation of skin was studied on two strains of mice BALB/C and Swiss.The subjects were divided into various groups :normal group, cyclophosphamid (CP) inhibited group, cyclosporin A (CPA) inhibited group, and the group processed with DY1. The onset of reject phenomenon of the graft and the completed reject of the graft in the groups of mice using CP, CPA and DY1 were more delayed in comparing with the controlled subjects. The cell numbers decreased and the percentage of transformed cells also decreased in all groups using CP, CPA and DY1

By the technique of indirect immunofluoresceine using 18 diverse markers, in the hospital K- Ha Noi, study was performed to determine the capacity of foreign antigene expression of tumor cells in the cell surface making them identified by immunology system through HLA system on NPC < 75 years old age patients. This system played an essential role in the regulation and realization of immune response.

Our descriptive-analytic observation study about clinical manifestations of SARS was performed on total 34 patients admitted to National Institute for Research on Tropical Medicine, Hanoi, Vietnam. There were one patient with COPD and another patient with hypertensive heart failure. The mean age is 37.4 14.4 (18-76), males (13/34 (38.2%) and females 21/34 (61.8%). The mean incubation time is 8.73.6 (2-16) days. The common signs and symptoms are fever (100%), fatigue (94%), dry cough (67.6%, myalgia (55.9%), abnormal lung sounds (52.9%), headache (50%), chest pain (50%). There were 13/34 patients with diarrhea (38.2%), 8/34 with conjunctival and integumental congestion (23.5%), 5/34 with coryza (11.8%) and 2/34 with productive cough (5.9%), 11 severe patients had marked findings of respiratory failure with tachypnea, SpO2< 85% and abundant abnormal lung sounds, including 4 patients required BiPAP ventilation support. The mean age of these severe patients (48.714.7) is significantly higher than of remaining patients (32.011.0) with p value=0.0008. All patients have survived and have no fever after 10.5 days on average. In conclusion: the clinical manifestations of SARS patients in our study are not specific as fever caused by other common virus except findings of respiratory failure and the diagnosis should base on epidemiologic factors and chest X-ray imaging. The old age and reparatory failure degree may be factors associated with progressive disease.

93 cases of hyperuremia were treated by the “Thong Phong hoan”, a traditional formula at the Military Institute of Traditional Medicine. Among them, patients with hyperuremia and gout were 40-60 year old, occupied a part of 70%, 94.6% in male and 5.4% in female. 76.4% of cases had got 1-5 year duration of the disease, 12.9% > 5 years old and 2.1% > 10 years old. Consuming much of alcohol, meat and abusing tobaco were the common habits of studied male patients. After 30 days of treatment, the preparation exerted the effect of dramatical decrease of uremia, with good results 76.3%, medium 18.3%, bad 5.4%.

In this study, 48 long-term exposed people with polychemicals (the male/female ratio is 1/3, the age from 23 to 44): such as organic and iso-organic acids: benzene, toluene and their coequals were investigated. 17 normal people not exposed with polychemicals as the control group. Results were shown following: quantity of erythrocyte was lower than control group but not significantly. Leucocytes especially neutrophils reduced significantly (p<0.001). 15/48 cases (30%) appereared lymphoblast. There is no difference in platelet between studied group and control group
