[Comparative, quantitative and morphological investigations (automatic image analysis--micromorphometric analysis) of myocardium of rat isoprenalin treatment (author's transl)].

The alterations of areas of myocardium of male rats (2, 4, and 6 months) are investigated after isoprenalin treatment (0.05 mg/kg body weight and day i.p. for 30 days). The investigations are carried out using automatic microscope picture analysis, morphometric point counting and resp. Both methods yield the same qualitative results: The effect of isoprenalin is dependent on age and yields for old rats (6 months) only very little morphometric alterations in the myocardium. The automatic microscope picture analysis is a very effective method of investigation (45 seconds/cross section).
