  • Title: [Histochemical investigations in the experimental unilateral cryptorchism of the dog after HCG-treatment (author's transl)].
    Author: Weissbach L, Heinemann I, Goslar HG.
    Journal: Acta Histochem; 1975; 52(1):62-70. PubMed ID: 241190.
    Abstract:
    The behavior of various enzymes in the orthotopic and dystopic dog testis was examined under the conditions of experimental unilateral cryptorchism after HCG-treatment over a period of 3 months. The following findings could be obtained: 1. Under the HCG-application the orthotopic impuberal testis there was a change of behavior of the enzyme in the tubuli and Leydig-cells in comparison with test animals. A loss of LDH of the epithelium of the tubuli can be avoided through HCG-treatment. 2. In the dystopic testis of the impuberal animal, HCG cannot avoid this loss of LDH in the epithelium of the tubuli. In the Leydig cell complexes the Glucose-6-Phosphate-Dehydrogenase shows an increase of activity. 3. In the Leydig cell complexes of the impuberal testis an apparent loss of LDH is noticeable in the epithelium of the tubuli, while the non-specific esterase, SDH and the Glucose-6-Phosphate Dehydrogenase increases in activity. The activity of the Leydig cell complexes shows the expected stimulation. The present results prove that under a large dose of HCG-treatment can lead to different changes in the enzymes of the orthotopic testis of dogs.
