Remote Sensing and GIS technology was studied in 2003 to detect and predict the malaria risk in Ham Thuan Nam district, Binh Thuan province where malaria is endemic. The results showed that there was a strong relationship between natural, environmental and socio-economic indicators and malaria transmission in different areas of the district. The malaria morbidity rate from 1996 to 2002 and enviromental parameters such as land cover, vegetation, climate, meteorology... were used for building up a map to show the risk of malaria of the district through the retrospective and existing data SPOT, LANDSAT and ASTER satellite imageries. This map is corresponding with the malaria stratification maps of the district. Based on this malaria risk map, malaria situation and epidemic can be detected and prevented

Mosquitoes and larvae were investigated in the forests, edges of forest and other landscapes in the jungles of U Minh Thuong and U Minh Ha during two years of 2002 and 2003. A total of 15 species (24.19% of total mosquitoes species found throughout the country and 37.5% of those in the Southern Vietnam) was found, some of which were typical species of the water forest fauma. A mingle species composition of flood plain forest fauna with presence of An. paraliae, An. umbrosus, An. separatus... and coastal brackish fauma with An. sundaucus and An. nimpe found in the study sites suggests that the forests narrowness, forest fires and other ecological damages have caused the changes of species composition and distribution of mosquitoes of forest fauna

In studying the relation of blood stagnation syndrome and rheumatoid arthritis, the incidence and the severity were evaluated on 78 subjects of rhumatoidal poly arthritis (4 males, 74 females) aged 38-83 in Toyama Hospital, in April 2001. The incidence of blood stagnation in 53.8% following Terasawa is related significantly with the progress of rhumatoid poly arthritis, using the indication of Lansbury activity (p=0.083). This indicator increases dramatically in 5 patients of blood stagnation after 6 months (p=0.043). The results showed the relation between the level of stagnation and the activity of arthritis

Remote sensing and GIS technology was studied to detect and predict the malaria risk in Ham Thuan Nam district, Binh Thuan province where malaria is endemic in 2003. The result showed that: there was a strong realationship between natural, environmental and socio-economic indicators and malaria transmission in different areas of the district. The factors affect to ecological and developmental environment of mosquite and make advantage developmental condition for mosquite and conversely. GIS method is effect tool to define the factors and play a basic role for building up a map to show the risk of malaria. Remote sensing material and methods to deal with information provide important, objective information as NDVI index. The vary of the index together with another index as geography, climate... are important index in building epidemic forecast system early.

ELISA technique was used to detect Gnathostoma spinigerum in human. Antigene sample was prepared from G.spinigerum. 9 cases were determined as G.spinigerum infection. Antibody titres were found to range from 1/400 to 1/3.200. Results showed the efficacy of ELISA technique in the diagnosis of Gnathostoma infection

The authors studied epidemiology of forest malaria through a cross-sectional community based study in one province, central Vietnam. A total of 4036 individuals were investigated in 2004. Results: the prevalence of antibodies to P.falciparum was constantly about 20.5% and the prevalence rate of malaria parasite was 13.3%. Multivariate analysis showed that the regular forest activity was the main risk factor for malaria infection (OR = 5.51, p< 0.005). The population- attributable fraction for regular forest activity was estimated to be 99.5%. The results confirmed the major role played by forest activity on the malaria burden in this area and provide the basic for targeting control activities to forest worker. New interventions based on insecticide-treated materials need to urgently evaluated like: bed nets, hammocks...

Insecticidal effects of Agnique MMF were investigated in the coastal brackish water shrimp farms in the Tan Thuan commune, Dam Doi district of Ca Mau province in 2000. The investigations were made in terracotta jars and shrimp ponds with the surface area 30m2 and 1000m2 each. Agnique MMF was found to have a high and fast killing effect on larvae of An.sundaicus at all three testing doses of 0.3ml/m2, 0.4ml/m2 and 0.5ml/m2. Especially larvae at instars of III, IV and pupae. However, the insecticide produced a low effect on Culex sitiens killing larvae of IV ins tar and only retarding larvae of I, II, III instar. The residual effect of Agnique MMF was found to be 14 days in the terracotta jars and 6 days in the ponds. In the direct observations, Agnique MMF was found to have no negative effects on rearing shrimps

The survey was performed on 144 patients with hypertension in Dong Thap Medical-postal Center between 2003 and 2004. Results: The patients' awareness of their hypertension had much limits, 62.5% of patients unknown the disease, 61.81% detected their-self disease by chance, so 95.83% had not blood pressure monitored, 90.97% were not treated regularly and 7.64% were not treated. Health education and treatment record had good results. The percentage of patients had blood pressure monitored increased by 61.8% (compared with 4.17%), regular treatment 46.53% (compared with 1.39%).

The squamule button mushroom Agaricus blazei Murrill was fruifully cultivated in Da Lat, VietNam, under similar procedure at large scales with white button mushroom A. bisporus, giving lower biological efficiency (biomass of fresh fruibodies harvested per unit of dry composts used). The prefectful development of fruibodies was described and a minireview on their medicine - food value was discussed
