Background: In the period 2006-2010, a investigation on medical arthropod has been conducted\r\n', u'Objective: 1) To determine species composition and distribution of medical arthropod. 2) To find species transmitted disease \r\n', u'Subject and method: The cross sectional, descriptive and analytic investigation was conducted in 3 communes along the Ho Chi Minh road in Cao Bang province. \r\n', u'Results and conclusion: : A total of 3.437 of samples of medical arthropod belonging to 96 species have been collected including: three species of flea (Siphonaptera), two species of tick (Ixodoidea), four species of chigges (Trombiculidae), ten species of mites (Gamasoidea), twenty four species of flies (Muscoidea), and fifty-three species of mosquito (Culicidae). They belong to 39 genuses, 17 families, 3 orders: (Siphonaptera, Acarina and Diptera); two classes (Insecta and Arachnida). \r\n', u'Some species having epidemiological role such as Aedes albopictus, Culex tritaeniorhyncus, Cx. quinquefasciatus, Cx. vishnui ... were predominant at all study sites. Anopheles minimus, the main malaria vector, was mainly collected in cattle- sheds in Truong Ha and Bach Dang communes. \r\n', u'

components and biological properties of seed and root of Momordica cochinchinensis (Lour) spreng in Vietnam showed that: the content of lipid in seed nucleus is very high 56%, seed membrane 23%, root 1.73%. Alkaloid exists in seed nucleus, not exist in seed cover and root; tanin was much in seed nucleus and little in seed cover and root; glycoside was much in seed cover, root and little in seed nucleus; flavonoid was much in seed nucleus, little in seed cover and root; saponin was much in root and little in seed nucleus and seed cover. Saponin in Momordica cochinchinensis (Lour) spreng can inhibit different kinds of virus and microorganisms. Extracted material and solvent rate decided antivirus and antimicroorganism activities of saponin
