    Occupational exposure to emissions of photocopying machines in Iloilo City: An exploratory study
    Becodo, Cristina M.; Dignadice, Zynie B.; Gaviola, Ma. Thessa Urdolyn M.; Jumares, Analyn G.; Nievales, Cathy Q.; Panizales, Vanessa Grace L.; Teruel, Josie A.; Tingzon, Glynis S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-04)
    Photocopying is a profitable business in Iloilo City. The photocopying machines are known to emit ozone and volatile organic compounds. This study aims to determine whether long-term exposure to photocopying machines will have adverse health effects on the operators. The group extracted blood samples from the respondents; had them undergo chest x-ray examination; answer questionnaires and checklists. From the blood samples, the group determined the WBC count, differential count and serum albumin, total protein and uric acid of the respondents. From the chest x-ray examination, the group aimed to see particles from photocopier emissions deposited in the lungs. From questionnaires, the group aimed to determine the operators’ common health complaints. From the checklists, the group aimed to know if the photocopying establishments have a suitable working space area and ventilation. The group aimed to determine the effect of years and hours of exposure to photocopiers; number of machines; ventilation; working space area; kind and number of toner on WBC count and differential count; health complaints; serum albumin, total protein and uric acid levels; and chest x-ray results of the respondents. Results showed that years and hours of exposure had no significant effect on the photocopier operators. However, other factors such as the number of machines, working space area and ventilation, number and kind of toner had significant effects on selected cell and serum levels in the blood of the operators and on their common health complaints. The group concludes that exposure to photocopying machines have significant effects on the health status of the photocopier operators based on the common health complaints they frequently experience, white blood cell count and differential count and blood serum levels.

    Andal, Julie Jane F.; Ayongao, Jamela N.; Caton, Kate Alyssa A.; Parcon, Prem Patrick P.; Sedayon, Niña Marie Y.; Villanueva, Roena Nicole V. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    World Health Organization reports that diarrhea is the fourth leading cause of death among children less than five years old and the third leading cause of illness among the children. The Philippines ranks second among thirteen countries included in the census in terms of the number of diarrhea cases causing 10,000 deaths every year. Main factors in the transmission of diarrheal diseases are: children not washing their hands due to lack of access to water and basic sanitation facilities, poor hygienic practices, and handed down practices from parents. Experts note that the incidence of diarrhea may easily be lowered by simply having kids wash their hands with water and soap. Therefore, the purpose of this project is to introduce to the community ways and means of preventing and managing diarrheal diseases by boosting the level of knowledge and introducing hygienic practices through the development of community-wide education programs that range from promoting healthy lifestyles in order to prevent disease and providing the community with safe potable water supply in Purok V- Serum Bukid, Barangay San Nicolas, Buenavista, Guimaras. Efficient uses of health services, adopt self-care practices and active participation in the design and implementation of health programs were also promoted.

    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.

    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.
