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.

The study conducted on 58 premature neonate underweight infants at the Department of Resuscitation of the Pediatric Hospital N02 from Febuary 2000 to December 2002 had showed a high mortality of 74.1%. 100% of premature neonate underweight infants under 850g at birth died. The died infant had lower weight at birth, mean arterial blood pH was lower, mean arterial blood PaCO2 was higher. CRIB score had prognostic value to predict the mortality of premature neonate underweight infants using ROC curb and the undercurb superficial zone

The study was conducted from September 2003 to April 2005 to assess results of the mass deworming campaign in 5 primary schools in Quynh Luu district, central province of Nghe An. A pre-intervention survey showed a cumulative worm prevalence of 98%, of which the highest rate was Trichuris infection: 85.1% followed by Ascaris: 83.6% and hookworm 30.3%. No difference of infection between females and males was found. Mixed infection was high with 54.3% had co-infection with Ascaris and Trichuris (88%), and 24.8% had triple infection, while a low single infection rate (20.8%) of which Trichuris was predominant, was found. A low prevalence of high intensity of infections was found with Ascaris (6.5%), hookworm (1 %), Trichuris (0.5%) while a high prevalence of low intensity was found with all examined samples. The worm prevalence was found reduced after periodical mass deworming (every six months) with mebendazole 500mg, single dose. The cumulative infection reduced from 98% to 84.5% after six months and 72.2% after 18 months. Similarly, the Ascaris infection came down from 83.6% to 52.7% and 32.7%, the Trichuris from 85.1% to 70.6% and 56.1%. However, hookwonn infection remained nearly unchanged (30.3% to 31.3% and 31.1 %). The high and moderate intensity of infection was also reduced after intervention. The egg counts were reduced by 60% after 6 months, 73% after 18 months (after the third treatment) with Ascaris. Accordingly, it was reduced by 40% and 70%, respectively with Trichuris. No changes were found with hookwonn. The intestinal wonn infection control project supported by WHO has been a successful project in tenn of both technical and social aspects. The project was performed with good compliance of school children, their parents and teachers. Expertise and qualification of the provincial staffs were also enhanced with regard to public health in general, and intestinal worm infection control, in particular.

A cross sectional study was carried out on 866 children under 5 years old and all mothers with children under 2 years old in 2 villages of Cai Be district, Tien Giang province (one village often suffered by flooding and one village rarely had flooding). Household KAP interviews using structured questionnaire have been conducted. The weight and height of all children were measured. Results: In two villages, the percentage of malnourished children was still high (21.24%). Simultaneously, obesity in children under five (1.7%) emerged as a new health issue. All these risk factors: educational status of fathers and mothers, practice in feeding (giving the child fluid during 24 hours after birth, feeding during the child experienced diarrheae), starvation of families, knowledge on growth chart, time of first feeding the baby with supplementary food, time of weaning were investigated. There is no statistic significant association of those risk factors with nutritional status of children under five between the two villages

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.
