[Interaction between muscle cell and external mechanical field: a model study].

We have suggested a mathematical model of the muscle cell membrane on the basis of the thin elastic rods theory which takes external mechanic effects into account. We have also performed a quantitative analysis of deformation of rodent shin muscles when exposed to hindlimb suspension. Maximal deformation is shown to be typical for soleus muscle fibers and their magnitude is connected with stiffness of the cortical cytoskeleton.

[A method for assessing the microfloral status of the human intestines by the quantity of adhesion-active bacteria and by the type of adhesins].

The method for the evaluation of the state of intestinal microflora in the diagnosis of enteric diseases by the determination of the number of actively adhesive bacteria and the type of adhesins in the primary culture of human microflora has been developed. This method permits the simultaneous analysis of all colonies grown in a given Petri dish by the sign of their adhesion, which eliminates the possibility of mistakes due to the occasional choice of colonies, as it may happen in the agglutination test. The time necessary for the study of adhesive properties is reduced, as the result is evaluated as early as on day 2 after the inoculation of the seed material.
