In cell-free supernatants of liver tissue homogenates we determined the activities of N-acetyl-beta-glucosaminidase (beta-NAG, E.C. 3.2.1.30), a lysosomal glycosidase that is involved in proteoglycane metabolism of connective tissue. Beta-NAG-isoenzymes were demonstrated by electrofocusing in thin layers of polyamide gel. The results showed statistically significant correlations between beta-NAG activity and morphometrically assessed quantities of connective tissue, and of mesenchymal cells found in the latter or in the whole specimen, respectively. Demonstration of tissue or serum levels of beta-NAG or its isoenzymes provides a readily practicable method for assessing mesenchymal activities of the liver.</p>","PeriodicalId":76159,"journal":{"name":"Microscopica acta.

Vital microscopic results with marked proteins using the blue light luminescence technique indicate a movement of fluid along the connective tissue fibres. Furthermore, the findings suggest that the elastic fibres play an important role in this movement. It may also be possible to elucidate the extravascular pathway for molecules by means of the cathodoluminescence technique in the scanning electron microscope. The investigations were performed using the mesentery of mammalians anaesthetized by Nembutal. The biological material for cathodoluminescence applications was selected from animals without injection of luminescent dye as well as with animals following intravenous injection of marked proteins. Two techniques, critical point drying and freeze drying, were used in the preparation. Stained and unstained tissues were investigated in the scanning electron microscope with a special cathodoluminescence detector system. Simultaneously observations of the tissue surfaces were performed by means of the secondary electron or backscattered electron mode. The results obtained agree with the findings observed by the blue light fluorescence microscopy and confirm the concept of an extravascular fluid pathway along the elastic fibres in the tissue.</p>","PeriodicalId":76159,"journal":{"name":"Microscopica acta.
