Study the effect of Laser rays on the vitablites (protoscolesis) Larveal stages of Echinococus granulosis which infested in the experimental animals (gunia pigs )

Abstract

The present study ,we investigate the effect of Laser radiation of wave (325)nanometer (5) minute effect on the viability of  protoscolices the larval stage of Echinococcus granulosus. When  exposher to different wave of Laser .When increased the time of exposher to the wave there is reduction of violability of protoscolices also the effect of radiation on the development protoscolices in Ginea pig .The present Lethal Dose (LD50) of protoscolices (400) nanometer period(15)minutes.
