This research was conducted so as to determine whether a relationship does exist between the time needed for the onset of Rigor mortis and the different types of death that can be applied on to the rats. The rats were killed four different ways. They were killed through suffocation, strangulation, drowning, and laceration and it was discovered that the rate of Rigor Mortis was fastest for those rats that drowned. This was followed by strangulations, then suffocation and then by laceration. Since the loss of ATP can account for the manifestation of Rigor Mortis, it can be concluded that the activities of the rats prior to their death generally dictated how early this phenomenon will be exhibited. This is the only relationship that seems to be exhibited. Based on the statistical test used, it was established that there is a significant different in the values that were taken. As to the existence of a relationship, there is not significant relationship that was established between the extent of Rigor Mortis and the different causes of death and this can be attributed to the very slight difference in the ties for the manifestation of Rigor Mortis between those that died by strangulation and suffocation.

This thesis is a comparative study of the antibacterial effects of the extracts of ampalaya, bawang, bayabas, duhat and ikmo on Staphylococcus aureus. The herbs were cut, decocted and applied to cultures of S. aureus using the KIRBY-BAUER agar disc diffusion method. The zone of inhibition, being the criteria of anti-bacterial property, the most effective extract had been derived from bawang secondarily thereafter, from bayabas, ikmo, duh.at and ampalaya, in that order.

San Felipe, Michael C. For many decades, the people of Pagsanjan Laguna have used the Bayati fruit in catehing fishes from the Pagsanjan River. Ripe fruits of the plant were dried, crushed, mixed with earthworms and thrown into the river. This paper aims to study the action and effect of this fruit on a fish living in the marine biome, particularly, damselfish. After mixing traditionally prepared Bayati fruit powder with dried ground shrimps and making it into a paste, this was fed to the fishes. It was observed that the fishes showed great distress and disorientation before dying shortly afterwards. This was mainly due to the picrotoxin content of the Bayati fruit. Picrotoxin is occasionally used as a drug depressant among humas, an overdose of which is lethal.

Jr. The Mutagenicity and clastogenicity of gamma irradiated papaya extract at dose levels of 50, 100, and 150 kR were investigated using the Rec-Assay and Micronucleus test. Rec-Assay, an in vitro microbial assay using Rec+ and Re- strains of Bacillus subtilis showed significant mutagenic properties for 150 kR irradiated papaya extract even after 8 dahs of storage. Such mutagenic properties were not observed in papaya extracts subjected to lower irradiation dosages of 0, 50 and 150 kR gamma rays. Micronucleus test, an in vivo analysis for clastogenicity using mice as test organisms showed significant clastogenic properties for 150kR irradiated papaya extract after 8 days of storage. Such clastogenic properties were not observed in papaya extracts subjected to lower irradiation dosages of 0, 50, and 150 kR gamma rays.
