The diabetic patients are usually suffered from oxidation stress. Green tea is one of the good herbal medicines has been used for treatment of some diseases. Objectives: Evaluate change of antioxidant status in blood and effect of the green tea polyphenol on this change in the experimental diabetic rats. Methods: Using in vivo model to investigate some biological indicators in STZ - induced diabetic rats fed with high fat diet and to evaluate effect of the green tea polyphenol on the changes of these indicators. Results: Erythrocyte GPx activity and serum MDA concentration in STZ - induced diabetic rats was higher than that of normal and lipid metabolism disorder groups (p < 0.001) and effected of the green tea polyphenol. However, no change in erythrocyte SOD activity and plasma TAS level was observed. Conclusions: Green tea polyphenol improved blood antioxidant status in STZ - induced diabetic rats.

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

Study on 48 people, of whom 16 are male and 32 are female, from 23 to 44 years old. They were long exposed with poly-chemicals, such as organic and iso-organic acids: benzene, toluene and their coequals. The parameters have been used: phagocyte capablity and phagocyte index of neutrophils; E, rossett formed T cells. The results showed that: Phagocyte capability and phagocyte index of neutrophils decreased significantly comparing with control group (p<0.001)

20 patients with acute leprosy, 12 patients with chronic hepatitis, 34 patients with acute myelogenous leukemia, 48 patients with pharynx cancer. 31 normal healthy persons in the control group. Immune-complexes were fixed quantity by 2 methods: precipitating the immune-complexes with PEG having molecular weight 6.10¬3 and better method. Immune-complexes (+) were identified on acute leprosy, chronic hepatitis and acute diseases with the ratio of positive differences depending on disease, stage and the character of applying technique

115/400 Muong minority pupils of boarding school in Hoa Binh province, all studied subjects have 3 genarations of Muong minority (grandparents, parents and themshelves being Muong minority), from 15 to 19 years old. Using Sero check product of USA to examine the ratio of HBsAg. Results: 19.05% of the boys having HBsAg(+), 13.38% of the girls having HBsAg(+). So the ratio of HBsAg(+) in girls are lower than in boys but it is not significant. The ratio of HBsAg(+) at the age of 15 is 19.61%, the age of 16-17 is 14.74% and the age of 18-19 is 16.67%, there is not significant between groups

Green tea extract decreased lipid metabolism disorders on rabbit consuming cholesterol in experiment through the improvement of plasma TG, TC, LDL-C level. This effect depends on the doses of cholesterol and the drinking periods. The dose of 150mg/kg/day gave best effect.
