Abstract

Present experiments were undertaken in order to find out the most available diagnostic method for acute pancreatitis. Experimental dogs were divided into experimental group and control group. The experimental dogs were laparotomized and their pancreatic ducts were ligated for the induction of pancreatitis. The control dogs were laparotomized only for comparison. In addition to the complete blood count, serum amylase and lipase activities, serum glucose, total protein and albumin contents were measured daily for 11 days after the operation. Fecal fat droplet count by Sudan III staining and fecal trypsin activity examination by x-ray film digetion test were also undertaken daily. The results obtained were summarized as follows; 1. Serum amylase activities of the experimental group increased to peak on the third day and returned to the preoperative values on the eighth day. 2. Serum lipase activities of the experimental group increased to peak on the first day and returned to the preopertive values within six to eight days. 3. Serum glucose contents of the experimental group showed significant increse only on the first day. 4. Serum albumin contents of the experimental group decreased significantly during the experimental period. Whereas those of the control group significantly decreased only on the first day. 5. The experimental group showed marked leukocytosis, neutrophilia, and lymphopenia for the first 5 or 8 days. Whereas the control group showed only neutrophilia for the first 3 days. 6. The results of fecal fat droplet count showed some diagnostic value on the third and fourth day in only one experimental dog(No 1). No significant changes in the fecal trypsin activity were noticed in all dogs. 7. Histopathologically. all dogs of experimental group showed changes of pancreatitis. However the degree of the pancreatic lesion was not pararell to the degree of the serum amylase or lipase activity changes.
