    Microstructure of Liver Sausage (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0

    Notes: Cooked liver sausage was freeze-fractured and examined using scanning electron microscopy after fixation in either Zenker's solution or osmium tetroxide. The microstructure was characterized as consisting of dispersed protein particles and fibrous networks of protein surrounding variable-sized fat globules. If the fat globules were not thoroughly fixed they were dislodged from the freeze-fractured surfaces leaving vacuoles that could easily be mistaken for air pockets. The study demonstrated that the structure of liver sausage includes both an oil in water emulsion with protein as the emulsifier as well as dense layers of protein or protein-fat colloidal complexes.

    Fetal effects of cadmium in pregnant rats on normal and zinc deficient diets (1978)

    Notes: Summary This investigation has shown that not only the extent of fetal resorption and malformation but also the types of malformation seen in rats depend upon the strain used and day of gestation. Furthermore, the effects of zinc deficiency and cadmium administration on the fetus can be at least additive, as was seen for malformations. For fetal resorption, zinc deficiency potentiated the action of cadmium.

    Histochemical evidence of a functional heterogeneity in neonatal canine epiphyseal chondrocytes (1971)
    Springer
    Journal of molecular histology 3 (1971), S. 311-318 
    Details
    ISSN: 1573-6865

    Topics: Biology , Medicine
    Notes: Synopsis The chondrocytes of the neonatal proximal humeral chondroepiphyses of twelve purebred English pointer pups were investigated histochemically, using frozen serial sections, for chondroitin sulphate and for the following enzyme activities: lactate dehydrogenase, NAD and NADP transhydrogenases, glutamate dehydrogenase, isocitrate dehydrogenase, malate dehydrogenase, glucose-6-phosphate dehydrogenase, ATPase, succinate dehydrogenase, and UDPgalactose 4-epimerase. By using Alcian Blue with and without a prior digestion in testicular hyaluronidase, and Alcian Blue in the presence of 0.9 M magnesium chloride, it was found that about half the chondrocytes stained as if they were producing significant amounts of chondroitin sulphate. Only one enzyme, UDPgalactose 4-epimerase (which is involved in the biosynthesis of chondroitin sulphate), was found to have a similar staining heterogeneity. Therefore, it was concluded that the chondrocytes studied possessed a functional heterogenicity with particular reference to chondroitin sulphate synthesis while appearing morphologically homogeneous.

    Histochemical evidence of a functional heterogeneity of the chondrocytes of adult canine articular cartilage (1972)
    Springer
    Journal of molecular histology 4 (1972), S. 237-243

    Notes: Synopsis Twenty humeral heads were collected from 10 adult English Pointer dogs, fixed in 15% formalin containing cetylpyridinium chloride, decalcified, processed for paraffin sections, and cut serially. The articular cartilage was studied by staining principally with Alcian Blue in the presence of 0.4 or 0.9m MgCl2 with and without a van Gieson counterstain. The results of the differential staining procedures demonstrated the existence of two groups of chondrocytes with distinctly different staining affinities. One group reacted intensely for the presence of protein-polysaccharides within its cytoplasm while the other group completely lacked this property. An approximate proportionality of 3∶1 of the protein polysaccharide-positive and-negative chondrocytes was observed in the tangential layer and upper intermediate zone. In the lower intermediate zone, radiate zone, and zone of calcified cartilage, the chondrocyte types were present in equal proportions. Staining with Alcian Blue in the presence of 0.9m MgCl2 with and without a van Gieson counterstain indicated a further subdivision of the protein-polysaccharide positive group of chondrocytes. This blocking technique has been reported to distinguish between chondroitin sulphate and high mol. wt. keratosulphate. Thus, based upon a greatly decreased number of the blue-stained chondrocytes after staining with Alcian Blue in the presence of 0.9m MgCl2 the hypothesis is put forward that some chondrocytes produce primarily chondroitin suphate and others produce both chondroitin sulphate and keratosulphate.
