Capillary Supply During Development of Individual Regenerating Muscle Fibers

This study describes the capillary supply of individual regenerating muscle fiber during three stages of its development. Regeneration was induced by the injection of mepivacaine in the anterior tibial muscle of rats. Muscle fiber capillarization during regeneration was analysed in semithin sections, employing the following parameters: the number of capillaries around a fiber and the number of capillaries per fiber cross-sectional area. The results revealed that during development of regenerating fibers, the fiber cross-sectional area increased, the number of capillaries around each fiber increased and the number of capillaries per fiber cross-sectional area decreased. These data indicated a greater capillary supply of the individual regenerating muscle fiber during its early stage of maturation.     

Evaluation of metabolic profile tests using a computer]

A programme has been developed for the evaluation of metabolism profile tests in dairy cows by means of the TESLA-200 computer in the FORTRAN language. The computer evaluates and plots the metabolism profile from input data punched on tape in the IBM code by the Consul-253 electronic organization automatic device. The metabolism profile is represented as a column graph (histogram), the levels of individual parameters being confronted with the reference levels with a 95% confidence interval and the deviations are expressed in units defined as 1/2 of the confidence interval for each parameter. Calculation by this procedure enables the construction of a profile record in which any step beyond the 95% confidence interval in any parameters is seen very clearly. The computer also produces a table of exactly calculated values of deviations from the reference levels and makes it possible to determine the numbers of abnormalities for individual parameters in the animals tested.
