    Knowledge, attitudes, and practices on dengue vectors of households in Tumagboc Catachment Area, Miagao, Iloilo
    Arbizo, Jeric L.; Baldevarona, Rosa Lea S.; Caoyonan, Louise Asuncion D.; Gabasa, Marah Febcy J.; Mapa, Fernie Love D.; Patria, Elaine Joy M.; Tenchavez, Darlene Ruth B.; Trivilegio, Enna Fleur C.

    Previous studies have shown that knowledge, attitudes and practices have an association with the dengue vector control. As such, the independence of mosquito population on the sociodemographic characteristics and KAP of the household heads in Tumagboc Catchment Area, Miagao, Iloilo was tested. Based on the results, the household heads generally are unemployed, married females aging 41 to 50. Their households are composed of 4 to 7 members with no or one child below 15 years, and usually receive below P 1999 per month. Most of them are informed about dengue fever, but only one had suffered from it in the last two years. Moreover, they have moderate knowledge, poor attitudes, but good practices regarding dengue prevention. The container index is 2.71 for crude mosquito larvae and pupae population, and 0.39 for Aedes sp. The house index is 9.72, while the Breteaux indexis 13.19. Chi-square analysis at 0.05 level of significance confirmed the independence of mosquito larvae and pupae population from monthly income, dengue information reception, knowledge, attitudes and practices. A solid reason was the untimely conduct of the study in the beginning of the summer season, when stagnant water has dried up and with few vulnerable breeding sites.

    Anti-angiogenic properties of Cymbopogon citratus and Moringa oleifera using the Chorioallantoic membrane vascular assay

    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.
