[The content of SH-groups in the isles of Langerhans (author's transl)].

The detection of SH-groups was carried out on islets of Langerhans of sand rats, guinea pigs and NZO-mice. Following results are pointed out: 1. All cell types of islets reacted identically. Species differences are visible. The islet cells of guinea pigs have the highest content of SH-groups, in the islets of sand rats diminished, and in the islets of NZO-mice lowest. 2. The content of SH-groups is the exocrine pancreas of this species higher than in the exocrine tissue. However the succession is also NZO-mice < sand rats < guinea pigs.
