Lateral thermal damage along pulsed laser incisions.

The damage adjacent to incisions created in dorsal mouse skin by overlapping Er3+ and CO2 laser pulses of a duration of 250 microseconds is investigated histologically. It is compared to injuries induced by long-term heating. We demonstrate how the lateral thermal damage near the laser cuts can be explained by heat conduction.

[Histotopography of glycosidases in the accessory glands of the boar before and after castration].

The histochemical distribution of six glycosidases (N-acetyl-beta-glucosaminidase, beta-galactosidase, beta-glucuronidase, alpha-galactosidase, alpha-mannosidase and alpha-fucosidase) was investigated in the prostate, glandula vesicularis and glandula bulbourethralis of castrated and non-castrated adult boars. The functions of the glycosidases in the male accessory sex glands of the boar and their androgen dependence are discussed briefly.
