The mucous membrane of the caecum and colon ascendens of adult horses was first studied using light and transmission electron microscopy. In the surface epithelium there was an inconspicuous constellation of organelles, otherwise there was a lot of mitochondria as a source of energy for absorptive performances. Moreover, enlarged intercellular spaces exist(More)
Alkaline phosphatase in the endometrial and chorionic epithelium from the 22nd to 24th day post insemination was investigated according to the method of Hugon and Borgers (1966a, b). In the precontact phase the reaction products of this enzyme were found light microscopically in the caruncular and intercaruncular area in the apical part of the uterine(More)
The development of the bovine small intestine was examined in 24 embryos and fetuses by light microscopic, scanning and transmission electron microscopic methods. Special reference was paid to the genesis of the epithelium and particularly of the villi intestinales. The primitive intestine consists of one layer of epithelial cells surrounded by mesenchym(More)
In the 10th week of gestation the development of duodenal glands in the bovine intestinum starts by circumscript epithelial proliferation. Their secretory channels are in contact with the crypts. Already in the early fetal stage ultrastructurally there are an inconspicuous equipment with organelles in the apical cytoplasm and single globular granules, which(More)
