19.460 newborn infants at 2 Obstetric and Gynecology Hospitals and various Hospital had been given a postnatal screening (22.43%) from the year 2000 to 2003. The rate of mother/families who opt for screening was increased from 9% in the year 2000 to 36-40% in 2003. In suburban area the rate of screening in the year 2003 was 7.5% verus 28.1%, 44.1% in urban area. The rate of re-examination is 4.18% and there are 5 false negative cases. The detection rate for congenital hypothyroidism was 1/9000 case.

In 2001, there were 37 outbreaks of measles with various sizes in the Northern region. 36 out of 37 outbreaks were confirmed by MAC-ELISA. Percentage of positive sera was 86.3%. The measles outbreaks became more seriously in mountainous areas. The measles cases occurred all the year, and focused on January to May, with the peaks were January and February. The distribution of measles by age group has changed to group of older children, with most of cases were in 5-15 age group. 64.5% of measles cases were not immunization. The ratio of non-immunization to immunization increased with age group

After integrating hepatitis B vaccine produced by National Institute of Hygiene and Epidemiology into the Expanded Program on Immunization (EPI), seropositive rate and geometric mean titre of anti-HBs of 12-24 month old children were 69% and 157 mIU/ml in urban group, respectively. The results were higher than rural group (48.6% and 107.2 mIU/ml, respectively). Seroprotective rate increased from 48.7% to 80.2% after booster dose. This rate was highest (93.3%) in children received the booster dose 8-10 months after primary immunization. In the different time of booster dose, level of anti-HBs of 12-24 month old was higher than before

Vietnamese ginseng leaves had the effect on the central nervous system, shortening pentobarbital-induced sleeping time in smaller doses and lengthening pentobarbital- induced sleeping time in larger doses. Vietnamese ginseng leaves extract (600, 1200mg/kg p.o) and its total saponin (200mg/kg p.o) significantly recovered the stress-induced decrease in pentobarbital sleep to the normal level. In the other hand, Vietnamese ginseng leaves extract and its total saponin have the invigoration and antioxidant effects

Study on the effect hypoglycemosis of extract from Sambucus nigra ssp. canadensis (L) R. Bolli flowers on streptozotocin-induced diabetic mice. A single daily dose of extract (equivalent to 0.4g flower/kg daily) were administered for 5 days or 10 days to the diabetic mice immediately following Streptozotocin injection. As a result, extract from Sambucus nigra ssp. canadensis (L) R. Bolli flowers inhibited glucose concentration in diabetic mice at the investigated dose. It is indicated that the flowers of Sambucus nigra ssp. canadensis (L) R. Bolli may be an effective agent for treatment of diabetes

Both ethanol extracts of the bark and leaves of Schefflera elliptica (Blume) Harms (Araliaceae) showed antistress effect on mice at the oral doses of 158 and 167 mg/kg body weight, respectively. The bark proved to be more effective than the leaves, and their efficacity increased with the doses. Both extracts possessed in vitro antioxidant activity at the concentrations of 50-100 mcg/ml, the bark also being more effective than the leaves. The total saponin extract of the bark exhibited antioxidant effects at the levels of 5-25 mcg/ml. So, saponins might be the chemical constituents determining the antioxidant activity.

A cross-sectional study on actual situation of using of borax and colour additive in 390 traditional food samples (Lean pork paste, roast pork, fermented pork roll, noodles, green rice flake cake, pyramidal rice dumpling) has been conducted in Ha Tay province during 2002-2003. The results have shown that 95.2% of lean pork paste sample, 79.3% of fermented pork roll, 10.9% of noodles, 60.0% of cake samples were found with borax-an unpermitted chemical in food. Color additive was found in almost examined samples

Materials and methods: Wild growing Adenosma caeruleum R.Br. (Scrophulariaceae) was collected at Dak Mil district (Dak Lak province) in July 2002 for oil preparation. The oil analysis was carried out by a combination of capillary gas chromatography and mass spectrometry. Results: The essential oil was obtained from the aerial part of the plant at the yield of 0.5% compared with dried materials. 38 chemical compounds were identified. The major components were thymol (24.67%), alpha-humulene (16.44%), thymyl methylether (12.59%), gamma-terpinene (12.26%), beta-caryophyllene (5.82%), beta-bisabolene (5.67%), p-cymene (4.58%), humulene oxide (3.59%) and caryophyllene oxide (2.76%).

Study on 5409 female employees who were directly taking part in agricultural production in 3 regions: the North 1794 persons; the Central 1805 persons; the South 1810 persons. 1218 persons were randomized for clinical examination: the North 418 persons, the Central 392 persons and the South 408 persons. 293/1218 persons were selected for examination of worm eggs. Results: the rate of gynecological disease was 19-23%; dermatological disease in the North was rate of 20.11%, the Central 23.97%, the South 37.64%; Muscular disease was 15.5-18.5%. The infection rate of ascaris was 78.5%, the negative rate was only 8.5%. The physical indexes of female employees were in normal limitation of Vietnamese people.

The serology epidemiological investigation on 2-10 years old children in 3 geographic areas of Thanh Hoa province after immunized by oral OPV vaccine showed a rate of protective antibody of 76.5% to all 3 types. There is no difference in the rate of children having protective antibody to type 1 and 2 but type 3 in these 3 areas. A difference of GMT among children in 3 geographic areas, and the last level is in Yen Dinh district. GMT to each polio virus type was higher than the protective immunity level (>8)
