Attenuated 3rd stage larvae of Dictyocaulus filaria, by continuos emission of visible Helium- Neon laser of 1mW and a wave length of 632.8 nm for 2.5,5,10 and 15 minutes, were dosed twice orally to four groups of five kids each. The first dose contained 1000 larvae and after five weeks a second dose of 2000 larvae was given . A 5 th group of five kids was left as control.  Results showed that attenuation at 2.5 min. exposure was insufficient as indicated by the increase in respiratory rate, eosinophilia and shading of larvae in the feaces. The results indicated that attenuation of Dictyocaulus filaria larvae at (5, 10 , and 15) min. exposure to laser radiation were efficient and safe to be used as attenuated vaccine .

Methods Of Treatment

Cardiologists pay great attention to the treatment of coronary heart disease (IHD), as well as prevention, improving the already known and developing new methods. Of the latter, laser therapy is of particular interest, in particular, the use of low-intensity laser radiation is promising, which is quickly gaining a place among the known non-drug methods of treatment in therapeutic practice.

High Intensity Light

A 100 ms exposure from a 5 mW helium–neon laser was sufficient to potentiate fully phytochrome-controlled germination in Pinusbanksiana Lamb. The energy requirement for the brief, high-intensity light exposure was comparable to that for a much longer, low-intensity light exposure. As a result, the laser may be valuable in studies of the germination process and the primary mode of action of phytochrome.

In the presence of circulating Evans blue a helium-neon laser injures the endothelium of brain surface arterioles in situ. The injury is known to selectively eliminate endothelium-dependent responses. The present study documents in mice the fact that such endothelial sites become selectively attractive to passing platelets that have been activated as a result of more severe injury upstream. We then test the hypothesis that the “capture” of platelets at the downstream site is due to loss of “classical” endothelial-dependent relaxing factor of acetylcholine (EDRFACh) at that site. EDRFACh is known to inhibit platelet adhesion/aggregation and is synthesized from L-arginine. We show that agents that would either enhance or reduce the synthesis of local EDRFACh reduce or increase the incidence of capture as predicted by the hypothesis. Thus NG-monomethyl-L-arginine (L-NMMA) and arginase that would reduce synthesis of EDRFACh enhanced platelet capture. L-Arginine, which would enhance synthesis of EDRFACh, inhibited platelet capture. In addition, L-NMMA and arginase enhanced platelet aggregation over the more severely damaged site upstream from the site of capture. Ex vivo studies of platelets harvested from treated mice showed that the platelets themselves were unaffected by the treatments that, except for arginase given intravenously, all involved topical application of the tested drugs.
