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%).

Whooping cough(pertussis)is a highly contagious respiratory disease,which mainly affects infants and young children.Vaccination is an effective measure to prevent pertussis infection.Due to the fewer side effects,acellular pertussis vaccines(aPVs)have replaced whole-cell pertussis vaccine(wPVs)in many countries.Despite vaccination coverage is high,the short immunity induced by aPVs is considered to be significant reason for the re-emergence of pertussis.For improving pertussis vaccine,genetically detoxified vaccine and live attenuated vaccine have showed obvious clinical results and other strategies including using novel adjuvants in aPVs,increasing antigen or packaging aPVs with nanoparticles also have good prospects.This paper reviews the antigen composition and protective effects of aPVs,vaccination programs in different countries,potential candidate components of pertussis vaccine and new strategies for prevention of pertussis.

An investigation on helminth infection was conducted in the mountainous district (Quy Hop) of Nghe An province in August and September 2002 showed that: the cummulative intestinal helminth infection rate was 68.4%, with the highest rate among the people aged from 6 – 9 years. Ascaris infection rate was 54.2% with the highest rate found among people aged from 10 – 11 years. Hook worm infection rate was 28.6%, most of all were adults. Trichuris was 10.8% with no difference of ages. Single infection rate was 45.5%, mix infection rate was 23.3%, mixed infection between Ascaris and hook worm was the highest 15.7%. There was no big differences of the infection rate in sex. The intensity of intestinal helminth infection was low with average of 1431 epg for Ascaris, 864 epg for hook worm and 112 epg for Trichuris. Community living conditions and their habits were found to influences the intestinal helminth infection

Currently, imported malaria trend to increased and account for advantage in malaria epidemiology characteristics due to increased population changes in Nghe An province. Malaria drug management also need to changes to suit the fact that previous malaria endemic areas, where has a little malaria patients so that demand on malaria drug reduced. Domestic malaria is strongly reduced. Parasite mechanism also changes according to advantage tendency. Imported malaria appear annually and in every areas so that malaria drug need to available from the villages health station to provincial health station with 1/1 ratio for drugs against P.falciparum and P.vivax

Foods, beverage and dietary are related to cancer-induced risks. These risks included putrid foods, smoking foods out, no preparing food in stict, toxic foods,... numerous alcohol drinks may lead to cancer. Thus, for cancerous prevention everybody must own self in dietary. The food suppliers are responsible for clean food supplying with safe-hygiene-food for consumers

Stress-related mucosal damages (SRMDs) usually happen in victims of natural or man-made disasters. Because of unexpected factors, it causes psychological, mental, and endocrine exciting. In addition to direct damages, stress damages cause ‘positive resonance’ result in more severe injury. The signs of disaster-related stress must be found in emergency treatment in order to provide prognostic treatments such as calming down, pain relief, treating of SRMDs and gastrointestinal bleeding due to SRMDs. After discharge, patients must be stabilized moral

The study was carried out on 58 premature newborn underweight babies at the Department of Rehabilitation of Pediatric Hospital, HCM City from Jan 1999 to May 2002. The babies have been monitored from the first 12th hour after birth to the discharge day of hospital. Results showed that premature newly born underweigh babies with disturbance of oxygene metabolism and acidosis blood metabolism had got the higher fatal versus the omes who had not. The ealier correcting of these disturbances will help to improve the mortality. It should increase the early use of surfactants at the Department of neonatal rehabilitation to reduce the risks of internal membranous disorders.

In 1969, Mc Cord and Fridovich discovered an enzyme that had an antioxidative activity – it was superoxide dismatase (SOD). In 1984, Cutler R.G determined the pathogenic roles of free radicals in biology. In 1986, Marman D mentioned the relationship of free radicals and origin and development of organism, relationship with pathogenesis and aging

In the group of male and female young subjects living in the South Viet Nam, body height is developed stably, reaching 166,1 cm in male and 154,7cm in female, who living in the family of worker, moving moderately and no having morbide sequellae. Thus, the height of young persons had been improved by 7-9cm in male and 5cm in female, in comparing with that of 25 previous years. The weight had been improved in the age group of 15-24 years in male subject, however in female it had been at the age of 15-19 then reduced lightly.

In this study, 123 normal pregnancies were performed 649 times of ultrasonographic examinations. Results: there is a correlation between the ratio of head/abdomen circumference and fetal age as following: primipare Y = 1.842633 - 0.029259X + 0.0000047X3, r = 0,777; multipare Y = 1.672611 - 0.022408X + 0.00000278X3, r = 0,795; (Y = Head/ abdomen circumference; X = gestational age). Determination of ratio of head/abdomen circumference will help making early diagnosis abnormal fetal development, so it's necessary to apply this ratio in clinical care
