| Abstract | ||
| The present study investigated the effect of the Neodymium- Doped Yttrium Aluminum Garnet (Nd: Y3AL5G12) Laser eradiation 1000 mw, against infection with secondary hydatid disease in BALB/c mice by inoculating the animals with protoscoleces of Echinococcus granulosus exposed to laser irradiation, for various periods 40,60,120 and 240 minutes, with viability of 70%,57%,50% and 40%, respectively, contrasted to the control set (mice inoculated with unexposed protoscoleces) along three months, depending on the evaluation of the total count of WBCs and assessment of acquired cell- mediated immunity, demonstrated by delayed type hypersensitivity test (DTH). The results showed considerable increase (p<0.01) in the total WBCs counting, in mice injected with irradiated protoscoleces, up to 13962 cell/cm3, in comparison to the control group 5420 cell/cm3, after 120 minutes, two months post infection. Moreover, there was considerable excess (p<0.01) in the foot pad thickness in treated mice, 2.94 mm after 120 minute (24hour post antigen injection), two months post infection, 2.86mm after 120 minutes (24 hours post antigen injection), 1 month post infection and 2.64 mm, 120 minutes (24 hours post antigen injection), three months post infection, compared with the control group 1.18mm, 1.80mm and 1.72mm, respectively. Results revealed that irradiation of Echinococcus granulosus protoscoleces with laser had a significant influence on the production of WBCs and stimulation of delayed-type hypersensitivity reaction in mice. | ||
