[Pathomorphological and morphometric evaluation of a model of aortic insufficiency in rabbits treated with taurine]. / Patomorfologicheskaia i morfometricheskaia otsenka modeli aortal'noi nedostatochnosti u krolikov pri lechenii taurinom.

In 45 experimental rabbits, subjected to trans-carotid aorto-valvulotomy in a month developed a congestive heart failure. When this group of rabbits was compared to the control group of 20 animals, in the course of complete pathomorphologic, histochemical and stereomorphologic analysis the following results were obtained: potassium oroticum did not show any efficacy at all; the efficacy of taurine in a dose of 10 mg/kg was low. Its effect was both direct and indirect acting through the autonomic nervous system.

[Motor and evacuatory functions of the human stomach during antiorthostatic hypokinesia]. / Motornaia i évakuatornaia funktsii zheludka cheloveka pri antiortostaticheskoi gipokinezii.

After overnight fasting test subjects exposed to head-down tilt showed an increase in the amplitude of stomach biopotentials, thus suggesting an increase in its contractile force. A provocative food test demonstrated an increase in the excitability of the stomach neuromuscular apparatus due to 30-day head-down tilt, which included an increment of contraction amplitudes and rates. The amplitude increase occurred both before and after food intake. However, an analysis of the wave amplitude composition showed a shift to the right which was most distinct in the fasting state. This indicated that the stomach motor activity in the digestive period showed greater resistance to head-down tilt. An increase in the asymmetry coefficient before and after food intake proportional to the head-down tilt duration suggests that the stomach evacuatory activity was inhibited.
