1.Isolation of Flavonoids from Excoecaria cochinchinensis Lour. var. cochinchinensis
Journal of Medicinal Materials - Hanoi 2003;8(4):103-107
The remedy Excoecaria cochinchinensis Lour. var. cochinchinensis (Euphorbiaceae) has been commonly used in folk medicine for the treatment of itches, furuncles, allergies. Previous reports have examined the chemical composition of the leaves, two compounds have been isolated and identified as gallic acid (FAD1) and ellagic acid (FAD 2). This study was carried out for the isolation and identification of the other chemical constituents. The leaves of E. cochinchinensis Lour. var. cochinchinensis were collected at Ha Noi city and Thai Binh province. The ethyl acetate extract of the leaves were successively chromatographed on silica gel G 60 and Sephadex LH-20 columns to afford two compounds named FAD 7 and FAD 8. The spectral analysis performed on EIMS, 1H-NMR and 13C-NMR has identified FAD7 as kaempferol 7-0-glycoside, and FAD 8 as kaempferol. These two flavonols were isolated from the leaves of the plant for the first time.

2.Influence of the iodized salt program in community on the determination of thyroid gland function by using radioimmunoassay and immunometric assay
Journal of Preventive Medicine 2002;12(1):36-40
The study was conducted on 82 simple goiter patients and 91 Basedow patients after at least one year using iodized salt daily. The results showed that the uptake of radioactive iodine (RAIU) by the thyroid gland of simple goiter and Basedow patients decreased after 2 and 24 hours taking an oral dose of radioactive iodine. Especially, the decrease was 40-50% in simple goiter patients. The concentration of T3, T4, TSH in the sera was as following: in the simple goiter patients, the concentrations of T3 and TSH were slightly decreased, and the T4 serum concentration was increased. However, all the values were still within the normal range of euthyroidism. In Basedow patients, the concentrations of T3, T4, and TSH have not changed.

3.Influence of use of iodine containing salt in the publicity on the thyroid function by some tests of nuclear medicine
Journal of Vietnamese Medicine 1998;6(2):1-5
The study was conducted in 82 simple goiter patients and 91 patients with Basedow’s disease after at least one year using iodized salt daily. The result showed:- The uptake of radioactive iodine (RAIU) by the thyroid gland of simple goiter and patients with Basedow’s disease decreased after 2 and 24 hours taking an oral dose of radioactive iodine, specially in simple goiter patients decreased 40-50%. -The serum concentrations of T3, T4, TSH were following: in simple goiter patients, the serum concentrations of T3 and TSH were little decreased and the T4 serum concentration was increased. However, all the values were still in the normal range of euthyroidism. In patients with Basedow’s diseased the serum concentrations of T3,T4,TSH have not been changed

Journal of Medical Research 2007;49(3):83-90
Background: Lipid peroxidation is considered that is one of the causes of pathological processes. Green bean is not only a food of high economic value but also a good medicine. Objective: To investigate the effects of green bean on (1) the lipid peroxidation in mitochondria of rat liver cell, (2) the index in blood of rabbits exposed to radiation: the activities of antioxidant enzymes (SOD, GPx), concentrations of MDA and TAS. Subjects and methods: In vitro experimental model was used to estimate the effects of green bean on lipid peroxidation in mitochondria of rat liver and in vivo experimental model was used to investigate the effects of green bean on the activities of free radicals in blood of rabbits exposed to radiation. Results and Conclusions: (1) Total green bean decreased the lipid peroxidation in mitochondria of rat liver cell without dependence onagents induced lipid peroxidation such as Fe3+.ADP/NADPH or Cumene hydroperoxid, (2) Green bean concurrently inhibited the decreased activities of SOD, GPx, TAS and the increased concentration of MDA in blood of rabbits radiated with 5 Gy dose. \r\n', u'\r\n', u'\r\n', u'

5.Silico-pneumoconiosis in workers of the factory of paved stone and construction in Binh Dinh Province
Journal of Practical Medicine 2003;442(2):20-22
Studying on clinical symptoms and respiratory function of 83 workers above 5 years professional age (86% male and 14% female) showed that there are predominantly 2 functional symptoms: chest pain and dipnoea, then sputum, cough and hemoptisis, two physical symptoms of deformity of the chest, vesicular murmur, were of higher rate. The incidence of respiratory total dysfunction accounts for 38.6% in workers. The incidence of silico-pneumoconiosis is 9.6%, mild form is common in most of workers

6.Serodiagnosis of Japanese Encephalitis (JE) by MAC-ELISA in Bach Mai hospital from 1997-2001
Journal of Medical Research 2003;23(3):21-27
Studying on 1405 sera were collected from 1159 patients ( male 58.55%; female 41.44%) with encephalitis syndromes which were treated in Bach Mai hospital. Using MAC-ELISA to estimate antibody for Japanese Encephalitis in these patients. The results were as following:
The general positive rate was 16.64%
The positive rates by MAC-ELISA were 16.54% (46/278), 10.31% (22/223),...and 13.36% (25/187) in 1997, 1998,...and 2001, respectively.
The positive rates for males were 58.55%; female 41.44%.
The positive rates divided by the age: 1-15 years, 36.84%; 16-60 years 63.16%.

7.The efficacy of integrated method controlling Xenopsylla cheopis and Anopheles minimus in Hoa Binh province
Journal of Preventive Medicine 2004;14(6):57-60
A research was conducted in 2001 and 2002 to evaluate the efficacy of remaining spray by using Permethrin 50EC to kill both kinds of vectors: Xenopsylla cheopis and Anopheles minimus, responsible for plague and malaria transmission, respectively. The results showed that Permethrin 50EC at the concentration of 0.5g/m2 was highly effective to kill Xenopsylla cheopis and Anopheles minimus and remained effective for 4 months

8.Evaluating KAP belong to 12 basic household health care skills for mothers with children under 5 year old at Mai Son and Vinh Bao districts
Journal of Practical Medicine 2005;0(12):51-55
The research studied practice real situation basic skills in health care for children of mothers and analysed few of factors related to lacks of knowledge, attitude and practice of the mothers. Objects were mothers having under 5 years old children. The research used descriptive method. The result showed that: Mother’s knowledge and practice by these 12 skills at both provinces achieved is low level. There are differences between mothers’s knowledge and practice. The low level of these skills and the differences showed more significantly in mountainous province. The IEC activities in both provinces showed not effectively. Local health workers did not pay enough attention to IEC, especially to counseling mothers to care healthy and sick children.

10.Preliminary study on the plasmids containing genes to encode antibiotic resistance of Shigella Flexneri strains isolated in Vietnam
Journal of Practical Medicine 2005;0(12):72-74
Recently, treatment for bacillary dysentery have meet many difficulty due to Shigella which antibiotic resistance. Most of Shigella strains also resistant to many antibiotics at the same time (multi-antibiotics). The aim of the research is finding out genes that are encoded antibiotic resistance, features about structure, activity mechanism as well as transmitable of the genes in community. Material and method: researched strains: 100 S.flexneri strains, standard strain: E.coli K12-J5-3. Tecnology: diffused paper slice. The result chosen Sflexneri strains that resistant multi-antibiotic from 237 primary strains. Among them, 100 strains have major resistant type is resistant to 5 kinds of antibiotic. The strains are chosen to receive to E.coli K12J5-3. The percentage of receipt are 56%. Most of receive type don’t get enough resistance to the 5 antibiotics.
