• In the previous papers we reported about the pancreas of marine mammals from Hokkaido as the resources of insulin. In this paper we dealt with the LANGERHANS islets and pancreas of marine mammals mainly from a morphological point of view. The weight of pancreas, number of the LANGERHANS islets and their distribution in pancreas were examined and are summarized in Table 1 and Fig. 1. The position of pancreas in a body and its external form differed slightly according to the species of the mammals. In the pancreas, LANGERHANS islets were found to be more dense in the head part than at the caudal part. The yield of insulin from the seal pancreas was examined using various extraction methods, such as DUDLEYS, SCOTTS and the acidic acetone methods. The results are shown in Table 2. The white powder of high potency, directly applicable for medical use, was obtained easily by the method devided by the authors, which is described in Fig. 2. Judging from the results obtained sofar and the availability of a comparatively large amount of the fresh pancreas from marine mammals in Hokkaido, these mammals may be the valuable resources of insulin.
