    Amarante, Hena Charma; Basquez, Mark Anthony; Brunio, Christian Allan; Dable, Nesel; De la Pena, Pamela-Di; Genterola, Janis; Oredina, Josette Marie; Padayhag, Dave (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)
    The study aimed to establish presence of radioactivity and concentration of heavy metals specifically lead and chromium in drinking water from wells within one-kilometer radius from the approximated center of the Calahunan dump site. Results showed that four out of twelve wells have positive results fro gross alpha activity and gross beta activity: wells 2A, 2C, 3A, and 3D. Well 2A, 2C and 3D registered alpha activities of 0.54, 0.033 and 0.369 Bq/L respectively while Well 3A registered beta activity of 1.0 Bq/L. Wells 2A and 3D exceeded the radiological limits set by WHO and PNSDW of 0.1 Bq/L for alpha activity and 1.0 Bq/L for beta activity. These wells that are found adjacent to the perimeter fence of the dump site registered alpha activity (wells 2A, 2C and 3D) and beta activity (well 3A). Radiological activities in all other wells sampled registered less than lower limit of detection. For gamma activity, all wells recorded 137- Cs and 134-Cs activity less than the lower limit of detection. For chromium and lead concentration using FAAS, only well 3C has a chromium concentration of 0.0952 ppm and this exceeded the PNSDW standard for chromium in drinking water (0.05 ppm) FAAS has not recorded any value for lead. For chemical constituent analysis using XRF, two wells in zone 1 (LA and IC), have recorded lead concentration of 0.9 and 0.136 ppm, respectively. In zone two, only well 2D registered a lead concentration of 0.248 ppm. In zone 3, well 3C registered a lead concentration of 0.397 ppm. For chromium concentration, only well 2A in zone 2 has a chromium concentration of 1.79 ppm. The spot interview and ocular inspection found out that the following garbage are disposed of indiscriminately tn the dump site: (1) Television picture tubes, (2) Dysfunctional Computer Monitors, (3) Used syringes and needles, (4) Hospital wastes, (5) Automobile batteries and dry cells, (6) scrap iron, tin cans, paint cans, paint cans, etc., (7) polyethylene bottle, glass bottles, and containers of similar types, and (8) other organic and inorganic wastes. Wells whose values for gross alpha, lead, and chromium concentration exceeded the standard are unsuitable for dinking and other domestic uses. The observation that wells (2A and 3D) near the Calahunan dump site registered higher-than-standard alpha activity may be a good basis to conduct further research particularly on the effect of leachate from dump site.

    The relationship between the intensity of common soil-transmitted intestinal helminthiasis and nutritional status among schoolchildren of Miagao-West Central Elementary School (MWCES), Miagao, Iloilo
    Alojepan, Jake L.; Lee, Raymond V.; Mediodia, Harold P.; Tansiongco, Venjune P.; Tubola, Keith Anthony V. (Division of Biological Sciences,, 2003-03)
    This study aimed to determine the relationship between the intensity of infection of common soil-transmitted intestinal helminths (STH): Ascaris lumbricoides, Trichuris trichiura and Hookworm species (Ancylostoma duodeuale and Necator americamus) and nutritional status among schoolchildren of Miag-ao West Central Elementary School (MWCES). This study also aimed to determine the prevalence of STH infection and nutritional status, either stunted or underweight schoolchildren. There were 285 study participants out of 436 schoolchildren of Miag-ao West Central Elementary School. Stool samples of the study participants were analyzed using Modified Kato-Katz Technique to determine the intensity of infections. The study participants were grouped according to the intensity of infection: negative, light and moderate to heavy. Nutritional status of the study participants was also determined and was classified into stunted, underweight and normal. Height-for-age value was used to determine stunting and weight-for-age value to determine those who are underweight. Frequency count was used for the descriptive analysis of the data gathered. The Chi-square test for association was used in the inferential statistics. The result of the study reveals that 51.2 % of the respondents were infected with Ascaris lumbricoides, 36.5 % with Trichuris trichiura and 4.9 % with hookworm. The findings also show that 16 8 % of the respondents were stunted and 27.4 % were underweight. Finally, study reveals that there is no significant relationship between the nutritional status and the intensity of infection of common soil- transmitted intestinal helminths among the schoolchildren of Miag-ao West Central Elementary School (p= 0 706)

    Anti-angiogenic properties of Cymbopogon citratus and Moringa oleifera using the Chorioallantoic membrane vascular assay
    Aldeguer, Justine Joy A.; Cañonero, Katrina Anne M.; Cortum, Lyzandra S.; España, Reina Marian E.; Hidrosollo, Manolo Angelo S.; Jaboneta, Abigail Louice D.; Peralta, Karla Danielle T.; Tiosayco, Angeline Veil C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-03)
    In the Philippines, the use of complementary and alternative medicine, such as plants, is beginning to become very common due to the rapidly increasing incidence of cancer in the country. Due to this increase, there have been claims that the most common plants have anticancer properties. These include lemongrass (Cymbopogon citratus) and malunggay (Moringa oleifera). However, there had been scanty literature to prove these claims. The aim of this study is to screen the crude methanol extracts of C. citratus and M. oleifera leaves for anti-angiogenic property using Chorioallantoic Membrane Vascular Assay (CAMVA). Non-lethal concentrations of the plant extracts were embedded into filter paper disks and inserted into the chorioallantoic membrane of the ten-day-old duck embryos. A negative control group of duck eggs were left unopened. After 48 hours of incubation, the number of blood vessels in the chorioallantoic membrane of the duck embryos was manually counted using a dissected microscope. Results showed that extracts of M. oleifera and C. citratus were able to inhibit blood vessel growth in the chorioallantoic membrane of duck embryo. Between the two plants, crude methanol extracts of M. oleifera (12.10+ 0.836) showed a lesser number of developed blood vessels than the crude methanol extracts of C. citratus (14.50+0.637). The anti-angiogenetic properties of these plant extracts could be attributed to the presence of phytochemicals such as citral, quercetin, kaempferol, and niazimicin which have been proven to have anti-cancer properties. In conclusion, M. oleifera and C. citratus have anti-angiogenic properties, hence they are potential sources of natural treatment for tumor.

    Microbiological water analysis of selected point sources in Iloilo City
    Alama, Jannie Mae G.; Calitis, Ma. Socorro Fatima P.; Cervantes, Ria Angela E.; Garcia, Marian Aisa C.; Otico, Pelita A.; Pacheco, Donna Ginn G.; Taquiso, Jezreel l. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2006-04)
    The recreational use of the Iloilo River according to the Iloilo River Master Plan entails various studies to support it being safe for swimming and other activities. The Department of Environment and Natural Resources (DENR) Region VI has done very few studies to determine this particular aspect of the Iloilo River. Thus, the present study was conducted to determine the bacteriologic content of water in selected point sources in Iloilo River, Iloilo City and the possible correlations to the incidence of health risks. Specifically the study aims to: (1) determine significant differences in the physico-chemical characteristics of water samples from each point source; (2) to determine the total and fecal coliform counts number for each water sample from the selected point sources; (2) detect the presence or absence of E. coli, Salmonella spp., and culturable Vibrios in water in selected point sources; (3) describe the incidence of health risks; and (4) correlate the heterotrophic plate count for total coliforms, Most Probable Number for Fecal Coliforms and the number of symptomatic respondents. The results of the study showed that the total coliform count for Point source A (HPC=6000/l00 ml) is higher compared to the standard set by the DENR (5000/100 ml) while Point source B and C are within the range. The concentrations of E. coli, in water samples A, B, and C (2400 MPN/100 ml sample) were found to be higher than the DENR standard for fecal coliforms for Class C Waters - fresh water, (200 MPN/lOOml sample). Although results indicate that the river water has high fecal contamination, there were no significant correlations between heterotrophic plate counts, Most Probable Number for Fecal Coliforms and the number of symptomatic respondents for each point source.

    Arcolas, Kezia Lois; Belleza, Noel Francis; De Leon, Mary Antonette; Lebin, Ma. Angeli; Nisorrada, Jea Rochelle; Silva, Alyssa Joy; Rafols, Sofia Aprille Grace (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-04)
    Improper home food handling preparation and consumption practices by consumers, inadequate hygiene practices, consumption of raw and unsafe food, as well as cross contamination by raw food are some factors and practices that have been implicated in food borne outbreaks in the home (Taulo et al., 2006). A survey was conducted to 27 households with children aged 0-6 years old from Barangay Lanag Sur, Tubungan, Iloilo. Of the 27 respondents, majority belong to the 30- 39(46.15%) age group, are housewives(65.38%) who were also in charge of preparing the food(53.8%), with monthly income ranging from 0-4999 pesos(57.69%). Among the respondents, six of them were randomly taken for sources of food sample which was tested for physical and microbial examination. Based on the survey, food preparation practices of households in the barangay is composed of washing, cutting, rewashing, boiling to cook/sterilize (for infant formulas), and cooling to room temperature. Majority of the respondents consume right kind of foods essential for nutritional use and use untreated spring water for its preparation. Food samples taken have pH values ranging from 6.15 to 6.975. The test for coliform indicated that two out of six households were positive for presence of coliform. Among the common illnesses of children recorded, 96% have had a history of acute respiratory infections and 84% have had episodes of gastrointestinal illness. Food handling practice in the community is simple and not capable of eliminating pathogenic substances like coliform bacteria totally.

    Abalajon, Karl Vincent P.; Caoyonan, Liza Marie D.; Fernandez, Natasha Andrea; Gequinana, Apple Joy F.; Lava, Lara Cristy S.; Millado, Justine Bennette H.; Rivera, Tess Corgette A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    Pulpitis has been the leading cause of morbidity among adults in Tubungan, Iloilo for the past three years. Pulpitis may develop from untreated dental caries as this make the deeper layer of the teeth more susceptible to bacterial colonization. Hence, this study aimed to determine the prevalence of and the risk factors associated with dental caries among school age children in Tubungan Central Elementary School. This study will further investigate the possible causes of the high in prevalence of dental caries, and eventually introduce means of decreasing its morbidity in the municipality. One hundred nineteen students from Grades one to six were included in the study. The dental caries status was determined using the DMFT (Decayed, Missing, and Filled Teeth) index. The dental caries status was determined using the DMFT (Decayed, Missing, and Filled Teeth) index. The nutritional status was assessed using Weight for Age (WFA), Height for Age (HFA), and Weight for Height (WFH) as parameters as parameters. The Oral Hygiene practices, socio-economic status and food intake of the respondents were determined intake of the respondents were determined through an interview schedule. The prevalence of dental caries was 75.6%, with a mean DMFT of 2.97. Grade 2 students had the highest prevalence (95%) and DMFT index (5.9) among the grade levels. The DMFT index of each grade level was found to be significantly different (p=0.000). There was no statistical significance between the DMFT indices between males and females, although the mean DMFT of females was higher than males. There is no significant association between the Socio-Economic status of the family and DMFT index of the respondents. Only food rich in cereals and starches had significant association with the DMFT index. It is recommended that the government should intensify the campaigns on Oral health alongside other forms of health education and dietary and nutrition advice.
