摘要：

The structural changes in adipose and fibrous tissues caused by 2- and 3-W IR laser irradiation are studied by the methods of IR and Raman spectroscopy and differential scanning calorimetry. It is shown that heating of fibrous tissue samples to 50degreesC and adipose tissue samples to 75degreesC by IR laser radiation changes the supramolecular structure of their proteins and triacylglycerides, respectively, without the intramolecular bond breaking. Heating of fibrous tissue to 70degreesC and adipose tissue to 90-110degreesC leads to a partial reversible denaturation of proteins and to oxidation of fats.
