Dynamics of hydration of cicatricial tissue during local therapy with collagenase preparations.

The components of complex dielectric permeability of cicatricial tissue at the frequency of 55 GHz were studied during local therapy of cicatrices with Fermenkol (a complex of collagenolytic proteases). Electrical characteristics of tissues in the microwave range were interpreted in terms of hydration parameters (total content of water in tissues and the ratio of structured and free water). The rightfulness of interpretations is discussed on the basis of the results of measurements of cell suspension models (native blood and its fractions brought to a standard hematocrit). The results attest to a relationship between hydration of the cicatricial tissue and its morphology and function.

[Vitamin D and calcium metabolism in relation to different levels of vitamins B6 and D]. / Obmen vitamina D i kal'tsiia pri razlichnoi obespechennosti vitamina B6 i D.

The influence of vitamin B6 deficiency on some vitamin D-dependent processes was studied in animals. The following parameters changing in relation to the level of vitamin D providing were investigated: activity of alkaline phosphatase in the serum and small intestine mucosa, the levels of Ca, P and parathormone, concentration of vitamin D metabolites and enzyme activity; and only 25-hydroxyvitamin D (25-OVD) concentration in the blood serum, under conditions of combined vitamin B6 and D deficiency was significantly lower as compared to cases with vitamin D deficiency alone. In the presence of vitamin B6 deficiency recovery of 25-OVD level in the blood serum, after vitamin D administration to the animals, had a tendency to delay as compared to that in the animals provided with vitamin B6. Vitamin B6 deficiency produced similar effect on 25-OVD 1-hydroxylase activity. The data obtained have evidenced a possibility of vitamin B6 influence on vitamin D metabolism.

[Experimental evaluation of the effectiveness of vitamin-enriched chopped meat products]. / Eksperimental'naia otsenka éffektivnosti vitaminizirovannykh miasnykh rublenykh izdelii.

The ration devoid of vitamins B1 and B2 and niacin, given to growing rats during 4-10 weeks led to growth cessation, a decrease in body mass and the development of vitamin deficiency that was expressed in a drastic lowering of red blood cell transketolase activity, and to increased effects of TDF and FAD. Inclusion into the animals' ration of cutlets enriched with vitamins B1, B2, C and niacin completely normalized their growth and biochemical parameters of their providing with vitamins B1 and B2. Routine cutlets were less effective. The feeding of rats with vitamin-enriched cutlets during 10 weeks did not induce any histological or histochemical disorders in their internal organs.
