title: [Qualitative and quantitative examinations of the corpus mamillare in the ontogenesis of male Tupaia belangeri and SPF cats].
abstract: The cyto-, myelo- and fibrilloarchitectonics of the Corpus mamillare were described in 33 male Tupaia belangeri at an age of 36 to 536 days of ontogenesis and in 37 male SPF-cats at an age of 39 to 584 days of ontogenesis. The fresh volumes of the Nucl. medialis and the Nucl. lateralis corporis mamillaris of Tupaia belangeri were determined and the growth of their fresh volumes described with the 6-parametric growth-function Likewise, the nuclei of SPF-cat were determined and these data were analysed with the logistic growth function The Nucl. medialis corporis mamillaris of Tupaia belangeri has a maximal fresh volume of 2.2 mm3 on the 82nd day of ontogenesis after which it procentually reduces by 16% to 101% of the ideal volume (1.9 mm3) on the 141st day of ontogenesis. The Nucl. lateralis corporis mamillaris reaches its maximum volume of 0.1 mm3 by the 90th day of ontogenesis, procentually reduces by 10% to 101% of the ideal volume (0.09 mm3) on the 169th day of ontogenesis. The half value times are 59 days of ontogenesis for the Nucl. medialis corporismamillaris and 48 days of ontogenesis for the Nucl. lateralis corporis mamillaris. In SPF-cat the Nucl. medialis corporis mamillaris reaches 99% of the ideal volume (11.7 mm3) on the 195th day of ontogenesis and shows a half value time of 86 days of ontogenesis. On the 229th day of ontogenesis the Nucl. lateralis corporis mamillaris reaches 99% of the ideal volume (0.57 mm3y and has a half value time of 83 days of ontogenesis.
