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 typhoid is common disease currently. 316 patients with typhoid diagnosed in Thanh Hoa hospital during 1994-6/1996. The wrong diagnosis of typhoid is frequent. The wide use of the anti-pyretic agents missed some symptoms, even complications. Most of physicians diagnose wrongly with the malaria that not basing on the epidemiology. Therefore, almost of patients wit typhoid in Thanh Hoa provincial hospital were treated by antimalarial drugs. It is difficult to prevent from the disease because it can be not control the salmonella typhi carrying patients after free disease

Bao tho tea prepared from black tea, stevia rebaudiana Bertonia and phylamin (a herbal preparation). A study on the bioactivity of Bao tho has shown that Bao tho tea had no acute or chronic toxicity, had a sedative effect and recovering the health. The preparation reduced the blood cholesterol concentration from 155 to 131mg%. Its coefficient of alpha radioactive protection was 0.33. The Bao tho tea supported the health of old soldiers in the nursing friendship village.

There have more than toxic microbial and viruses in the list of bioweapon for the bioterrorism and biowar. The fights for bioterrorism and biodisaster are activities of society and community. Individuals and community have responsibilities to protect, fight, and reduce the damage timely and effectively to bioterrorism. The professional facilities are responsible for investigating, isolating the germs, toxics and implementing the effective solutions for management of outcomes of bioweapon.

By studying the blood viscosity from 313 healthy people, 90 patients with hypertension, 20 patients with cerebral vascular accident (CVA) and 9 patients with polycythemia Vera (PV). The authors found that: The blood viscosity of the health people is from 3.21-5.19. The blood viscosity of the patients with hypertension is from 3.38-5.82. There was no difference from the viscosity of the health people (p>0.01). The blood viscosity of the patients with CVA is from 4.43-7.13; and of the patients with PV is from 6.31-7.87; Both of them are significantly difference from the viscosity of the healthy people (p<0.05 and p<0.01 respectively).

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

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
