Objective:To determine the pediculicidal activity of annona squamosa seed oil extract in emulsion.
Design:In vitro study
Setting:The MCU College of Pharmacy laboratory
Participants:Harvested head lice from 8 or more infested children in three local barangays(Barangay 81 and 86 Zone 8,Caloocan City and Barangay Potrero,Malabon City).
Intervention:Within 2 hours of capture,lice were placed in direct contact with annona squamosa seed oil extract in emulsion and a distilled water control and observed at regular intervals.
Outcome measures:Number of lice dead at each observation interval between 30 minutes and 1 hour of continuous exposure to the control substance and each concentration.
Results:There was a statistically significant pediculicidal effect produced among the various seed oil extracts in emulsion in comparison to the control.The 100 percent concentration produced a higher kill rate compared to the other concentrations.
Conclusions:Annona squamosa seed oil extract in emulsion produced pediculicidal activity.There was no significant difference between the 75 percent and 100 percent concentrations related to pediculicidal effect.The 100 percent concentration produced the highest number of lice killed at the one-hour time interval.

Objectives

General Objective:To determine the pediculicidal activity of annona squamosa seed oil extract in emulsion.
Specific Objective:1.To determine the pediculicidal effect of atis seed oil in emulsion based on:a.number of deaths at different concentration levels(75 percent and 100 percent)
b.killing time(30 minutes and 1 hour.
2.To determine the most effective concentration level of atis seed oil in emulsion as to pediculicidal effect.
