Certain immuno-haematological effects of laser irradiation.

The effects of low power He-Ne laser of 7 milliwatt power on certain immuno-haematological parameters were studied using fresh human blood samples. The parameters studied include electrophoretic mobility of haemoglobin, quantification of immunoglobulins, soluble immune complex levels, blood grouping, Rh typing and neutrophil function tests. Our results show that there is no significant change in the parameters studied after laser irradiation for 60 minutes except changes in the electrophoretic mobility of haemoglobin. In addition laser exposure causes haemolysis in all the samples examined.
