[Effects of slowly progressive constriction on the proximal pancreas of the rabbit].

Slow, progressive constriction with cellophane tape was experimented on the proximal segment of the rabbit pancreas. Histological examination of the distal segment over a period of 10-30 days showed the appearance of morphological changes reminiscent of chronic pancreatopathy in man. Stress is laid on the need for an experimental model suitable for the provocation of chronic forms, particularly if similar results can be obtained on animals of larger size.
