The investigation was conducted in one rural commune. Information was gathered about socio-economic status (SES) and food consumption of 544 households with 3 categories of SES. The results showed that the energy intake of household increased with higher socio-economic conditions. Rice, fat/oil, nut and sesame were most consumed in the households of the medium socio-economic status. The consumption of meat, fish, eggs and fruits tend to increase with better higher SEC. Vegetables consumption was low at all studied households.

The assessment of nutritional status of 6593 children under 5 years old in 6 communes/precincts showed that after 10 years, the nutritional status has been improved significantly in 3 indicators: rate of underweight children decreased to 34.0% from 53.2%; rate of stunt children decreased to 35.2% from 54.6%; wasting reduced from 10.7% to 7.9%. But overweight children increased from 1.2% to 4.0%.
Changes in nutritional status of children under 5 in some surveyed sites after 10 years (1985-1987 & 1995-1997).

The investigation was conducted in one rural commune. Information was gathered about socio-economic status (SES) and food consumption from 544 households with 3 categories of SES. The results showed that the energy intake of household increased with increase of socio-economic conditions. Rice, fat/oil, nut and sesame were most consumed in households of the average socio-economic status. The consumption of meat, fish, eggs and fruits tend to increase with better higher SES. Vegetable consumption was low at all studied households

A study on 222 households at 6 precincts and communes has shown that after 10 years, the real diet of household improved significantly number of rice, vegetable, tuber was reduced. While animal food, meat was increased 3 times, fish portion increased 2 times and eggs and milk increased 10 times, fruit increased 6 times and oil and fat level increased 2 times. The diet was more various and rich.

A major epidemic of DF/DHF occurred at Ha Noi in 1998, and 3348 cases of have been reported. Serological surveillance confirmed that the epidemic of dengue fever was caused by dengue 3 and dengue 1 virus types 32/37 positive samples were dengue 3 (86.48%). Dengue virus type 3 was isolated in 6 districts of Ha Noi

A prospective study was performed on 50 in-patients (62% male, 38% female) with pleural effusion due to primary lung cancer and pleural cancer at Bach Mai Hospital from October 2002 to November 2003, mean age of 57.9  14.4 year old. In 70% of patients the disease developed for more than 4 weeks. Common clinical signs were chest pain 92%, dysapnea 68%, prolonged dry cough 52%, hemoptypsy 16%. The syndrome of 3 reduces occured in 100% of cases. Effusion on right side is 60% vs 30% on left side. In 4%, there was bilateral effusion. Cancer cells notified in 30% of pleural fluid, and in 58.1% of pleural biopsies

141 marine samples have been tested for anti-microbial activity including representative: Gram positive bacteria, Gram negative bacteria, molds and yeast. Among them, 71 samples exhibited the positive result (accounted for 50.4 % of the total) against at least one of control microorganisms, 6 samples displayed the highest activity with the MIC value of 100 to 501/ml in the dillution method in 96- well plates. These data has been using to continue our programm in bioassay-guided chemical study

Screening 142 marine organisms extracts with three human cancer cell lines which were experimental grew in laboratory showed that: the number of agent having cytotoxic activity was rather high. Among 142 samples, 37 samples (26.1%) have resistant activity to at least 1 cell line. Of the 37 samples, 19 samples (7%) have resistant activity to two cell lines, 8 samples (5.6%) have resistant activity to 3 cell lines. The samples with remarkable activity have been collected with large quantity for chemical studies according to cytotoxic activity and related information
