KOSTOV, Y. and V. ALEXANDROVA, 2004. Laser-irradiation caused biochemical changes in cow blood serum. Bulg. J. Agric. Sci., 10: 757-762

The post-laser irradiation content of total protein, protein fractions, some enzymes and macroelements in blood serum was studied. Trial animals were divided into two groups. Cows of Group I (n=14) underwent fivefold irradiation in two main points - 49 and 50 for 2 min and three additional points - 27, 28 and 29 for 1 min once a day. Cows of Group II (n=27) were irradiated in the area of the uterine cervix for 6 min, once a day for 5 days on end.
We established that laser irradiation did not affect the contents of total protein, AP (acid phosphatase), CE, ASAT and ALAT-enzymes or that of macroelements calcium, phosphorus and potassium.
Laser acupuncture caused changes in the protein fractions, such as increased percentage of albumin and A/G coefficient and, after topical irradiation of uterine cervix - increased content of α1-globulins. After laser acupuncture, AP-enzyme (alkaline phosphatase) content was reduced. Of the electrolytes, magnesium content increased in both cow groups. Sodium was also found to increase in cows of Group II.

Key words: laser-irradiation, biochemical changes, cow, blood serum
