Background:The urocytogramme is a certain laboratory tests, although older. By studying the cellular elements from the wall of the bladder trigone desquamated in the urine, it allows cyto-hormonal diagnosis. It allows to assess the presence and importance of the biological effect of sex steroids. This examination is not commonly used because they are poorly known in our country. It's a review of how simple, noninvasive, inexpensive. Objectives:This study aims to learn about the value of urocytogramme in normal menstruation period of girls. Subjects and method:A study was conducted on 143 high school girls of Hai Ba Trung Secondary School, Hue city. The mean age was 15\xb18 months, completely puberty; the average weight was 45.7\xb16.8 kg; average height was 156.8 \xb18.5 cm. The duration of study was from September 2006 to May 2007. Results:Urocytogramme had the index which changed according to the phase of the menstrual cycle and correlated closely with sex hormone concentrations in the ovulatory phase. The IK index had the value in ovulation diagnostic phase with the sensitivity and specificity concentrations equivalent to LH and plasma Estradiol. Conclusion:Urocytogram was a useful test for the diagnosis of in normal menstruation period of adolescent girls. It was easy, cheap and truly reflected oestrogen activity to help doctors making decision for the treatment of lasting amenorrhea disorders.

Background: Ha Vi poultry market is a concentrated and spontaneous poultry business place. Ensuring environmental hygiene is not respected.\r\n', u'Objectives: To evaluate infectious situation of airborne fungi at a poultry market\r\n', u'Subjects and methods: From 10/2006 to 9/2007 a survey on the profile of airborne fungi was carried out at the Havi poultry - market. Total fungal spores averaged at 2.753 \xb1 576 cfu/m3, the highest sample is 7.120 cfu/m3\u2022 More than 10 different fungi were isolated. \r\n', u'Results: The common fungi are Cladosporium (30.13%), Penicillium (26.86%), Aspergillus (20.97%, composed of A.niger, A fumigatus, A.jlavus, A.clavatus ...), Fusarium (8.15%), some rare fungi (Rhizopus, Rhizomucor, Mucor, Alternaria, Curvularia, Absidia, Bipolaris ... ) 13.89%. The concentration of airborne fungi at the market was higher than at distance of 300 and 1000 m. The concentrations of total fungi and of each species are affected by some meteorological factors: they were higher in the end of spring, early of summer and autumn, lowest in the winter. The concentrations of Cladosporium, Penicillium were found to be positive correlate with humidity, Aspergillus, Fusarium with temperature. \r\n', u'Conclusion: It is necessary to propose the methods that can reduce influence of airborne fungi pollution to health of people \r\n', u'

Background: Pesticides have been used widely in not only around the world but also Vietnam; however, their misuse can cause many serious health problems. For this reasons, it is necessary to closely monitor the use of pesticides and their effects on the health of farmers. Objectives: To describe the kinds of pesticides, the symptoms and related factors of acute pesticide poisoning among flowers planters. Subjects and method: A cross-sectional analytic design was applied with a sample of 107 households in the Hong Ha 1 and Hong Ha 2 village of My Tan commune, My Loc district, Nam Dinh province from November 2005 to February 2006. \r\n', u'Results: There were various types of pesticide that were being sprayed in the flower planting villages. Almost all types were moderately hazardous. 85% of farmers experienced at least 1 symptom of acute poisoning after spraying pesticides. The most common symptoms were headache, dizziness, rash (accounting for 45-58%), followed by red eyes and musculoskeletal symptoms (approximate 40%). The effects of pesticides to the farmer\u2019s health were proved with the typical symptoms of toxicity, especially headache, irritation of the face, red eyes. The percentages of self-reported toxicity symptoms were associated with sex, age groups, following manual and pesticide exposure. Conclusion: The results suggested that various interventions is required in order to change the knowledge, attitude and practice of pesticide use among farmers in general and flowers planters in particularly.\r\n', u'

Background: Pesticides safety, plant protection chemicals are widely used around the world, especially in agriculture to protect crops. \r\n', u'Objectives: To describe the real statute of knowledge and practice of safe pesticide use among flowers planters and various other related factors. \r\n', u'Subjects and method: The cross sectional analytic study was carried out in 2006 to evaluate the current situation of knowledge and practice of safe pesticide use in 2 flower planting villages: Hong Ha 1 and Hong Ha 2, My Tan commune, My Loc district, Nam Dinh Province. Results:The results showed that knowledge on determining toxicity levels and the absorption routes of pesticides to the human body through land and water is insufficient. As for pesticide use practice, the percentage of planters fully utilizing safety work clothes and other equipments was low. Multivariate analysis found that there was a significant correlation between good practice and knowledge. In addition, some predictors of good knowledge were: highly educated, male and age. Conclusion: The findings also discovered the priority of improving direct communication on safe pesticide use among planters. \r\n', u'

Background: Heparansulfate Interacting Protein (HIP) is up-regulated in various human cancer cell lines at both transcript and protein levels. HIP expression is related to the differentiation status and cancer development. Objectives: To determine HIP in benign prostatic hyperplasia, prostatic intraepithelial neoplasia and prostate cancer tissues. Materials and method: Western blot method was used to determine HIP expression in 3 different types of prostate tissue, including 11 prostate cancer samples, 2 benign prostatic hyperplasia samples and 11 prostatic intraepithelial neoplasia samples. Results. HIP was particularly up-regulated in prostate cancer and prostatic intraepithelial neoplasia, indicating that up-regulation of HIP expression may be an early event in tumorgenesis. Conclusion: The expression of HIP was different between cancer, prostatic intraepithelial neoplasia tissue and benign prostatic hyperplasia. HIP may serve as a prognostic marker for prostate carcinoma.

Background: In recent years, some arbo viruses which causes acute encephalitis syndrome (AES) have been identified in serveral countries in the world such as Chandipura virus belonging to Rhabdoviridae family in India, Banna virus belonging to Reoviridae family in China. In Vietnam, apart from Japanese Encephalitis Virus which is considered as main cause of AES, there are a few intestinal viruses like Herpes symplex virus type 1 and 4 and Nam Dinh virus considering other causes of AES. Objective: To identify the hyppothesis that one virus strain parasitizing in mosquito in Gia Lai province causes AES in order to provide more information about virus strains which cause AES in Vietnam. Subjects and method: Aedes albopictus cell line clone C6/36 was used for the isolation of virus in 43 cerebrospinal fluid samples of patients who were treated in Gia Lai hospital, from January/2005 to July/2005. Result and Conclusion: One virus strain from a 3-year old girl in Gia Lai province was isolated in 2005. The virus coded 05VN225 has the morphology similar to other viruses belonging to Reoviridea family.The nucleic acid sequence of the virus was checked with specific primers of alphavirus and flavirus groups, Nam Dinh virus and Conti virus group B (reovirus) of the Reoviridae. The positive result was confirmed with reovirus primers. This member of the Reoviridae family was isolated from acute encephalitis syndrome in Vietnam in 2005. Further study on pathology of the virus is very necessary.
