Antihypertensive tea (AHT) was processed from Flos Sophorae, Folium Nelumbii, Radix Achyranthis Bidentatae, Radix Codonopsis Pilosulae, Flos Chrysanthemi, … in the form of filtered bag (3g/bag). Experimental study on subchronic toxicity showed that AHT was non-toxic. Clinical trial carried on 60 patients with hypertension (stages 1 and 2) receiving 9g (3 bags)/day for 30 days revealed that AHT produced good effects: blood tension reduced by 88.3%, clinical symptoms significantly improved, better changes in biochemical and hematological parameters, no side effects

In order to have the primary results of subtypes of T-lymphocytes in peripheral blood of progressive systemic sclerosis patients, 20 patients were studied. The results showed that the counts of TCD3 was 1505 + 505 (cells/ml), TCD4 was 738 + 332 (cells/ml), TCDs was 668 + 291 (cells/ml). There was no significant difference of T-lymphocytes between progressive systemic sclerosis patients and the healthy people. Especially, one patient with severe clinical and paraclinical manifestations had remarkable decrease of TCD3, TCD4, and TCD8.

Study on nursing caries syndrome of 197 children aged 2-3 years old in the kindergartens, located in districts, Ho Chi Minh city. 9.6% child were diagnosed as having nursing caries (at least one of the maxillary incisors having labial caries or/and erosion). 3 dietary factors, nocturnal bottle feeding, comforters, coated with sweeteners and use of fuices in the feeding bottle were found significantly associated with nursing caries. There was no significant characteristic with the exception birth order of the child, where the condition was significantly higher in the first born children as compared to the later issues of their parents

42 patients were diagnosed as scleroderma and treated at Bach Mai Hospital in three years (1991-1993). 90.47% was female, the age ranged from 18 to 63 years. The control group consisted of 20 healthy normal persons. Results: the rate of anti dsDNA positive with serum 1/10 was 30.95%; the rate of anti ANA positive with serum 1/40 was 71.42% in the patients with scleroderma. In the control group, there is no person who had anti dsDNA positive with serum 1/10. The rate of anti ANA positive with serum 1/40 is 10%. Positive anti dsDNA rate is not high (30.95%). There is no case of scleroderma which had negative anti ANA but positive anti dsDNA in the patients group. The appearance of anti dsDNA and anti ANA with digestive and cardiovascular disorder had a high rate. Anti ANA is more valuable in following the nephroinjuries in the scleroderma than dsDNA

Scleroderma is the autoimmune diseases. It has clinical characteristics of other autoimmune diseases such as: systemic lupus erythmatosus, juvenile rheumatoid arthritis…Appearance of antinuclear factors, rheumatofactors and increased blood gamma globulin showed that the immunity in this disease is abnormal. Study on 20 patients with scleroderma who were treated at the Allergy Department in two years (1984-1985) showed that: the ratio of leukocyte in the patients was not lower than that in control groups; the percentage of T lymph in peripheral blood was lower; B lymph in peripheral blood increased lightly; T gamma in peripheral blood was lower; the percentage of lymphocyte transformation with Con A and lymphocyte transformation with PHA were lower; lymphocyte transformation with PWM increased

Through analysis and synthesis, through induction and deduction methods, the discussion with students and post graduate students at Hanoi faculty of Medicine, author realized that dialeclical materialism played an important role in the methodology of understanding and practicing the medicine. It forms a basis for building up a theory and interpreting the achievements of scientific studies. It can solve the philosophic problems rainsing in the processus of research. It is a right science for reasoning theoretically the problems and bringing them into practice of the physicians.

The experiment was conducted by Lipschitz’s method on white rats of 3 groups, each included 12 animals going without food 18 hours before starting of study. The control group administered orally 1 time only 2ml of water/100g of body mass. The 1st group Dia Long 3g/2ml/100g of body mass, the 2nd group Dia Long 4.5g/2ml/100g of body mass. Rats of all 3 groups were injected subperitoneally 5ml of 0.9% salt solution on 100g of body mass for increasing urine volume. Results showed a diuretic effect of Dia Long, lasting for 6 hours after the use. Dia Long’s excretion effects on Na, K, Cl ions through the kidney were manifested obviously in the 2nd and the fourth hours after use with all the various doses.

The study was designed as perspective clinical trial, comparing before and after treatment with BSA 52 in 30 patients with drug withdrawal. BSA 52 supported the addicts to overcome the drug substinent symptoms and to recover promptly general health status. Effective time was between 2 to 3 days in average with a sucessful rate of 93.33% of all studies cases. No considerable side effects were observed during the trial
