[Experimental determination of the absorption coefficients of biological tissues]. / Eksperimental'noe opredelenie koéffitsientov pogloshcheniia biologicheskikh tkanei.

Procedure is presented for studying the coefficient of biological tissue absorption of radiation with the wavelength lambda = 1.06 mkm. The absorption coefficient is determined by the temperature values of biological tissue experimentally measured with thermopairs. The coherent radiation current falls on the surface of biological tissue. A mathematical model is formulated for biological tissue heating with radiation. Solution of Furier equation obtained by means of Green function is given. Using the relationship found, the energy absorbed by the biological tissue was calculated and the absorption coefficient of radiation with lambda - 1.06 mkm was determined. The results were analysed and the error of the obtained values of absorption coefficients of biological tissues under study were determined.

[Stimulatory effect of lactin combined with hyphotocin on galactopoiesis in rats]. / O stimuliruiushchem vliianii na galaktopoéz u krys laktina v sochetanii s gifototsinom.

Specific features of the effect of lactin and hyphotocin or their combinations on lactopoiesis were studied in experiments on female white rats being in the stage of fading lactation. In a morphological examination of the mammary gland it was discovered that changes characteristic of galactopoiesis increase under the influence of lactin are accompanied by milk delay in lactopoietic lobules. Hyphotocin that intensifies lactation increases milk secretion without inhibiting the physiological involution of the gland. Simultaneous injection of lactin and hyphotocin stimulates lactation and inhibits the morphological involution of the mammary gland.
