To clarify the relationship between changes in serum pancreatic enzymes and pathological changes in pancreatic parenchyma, this study was performed by using rat models with acute pancreatitis. The models were rats with edematous and necrotizing pancreatitis. Amylase, lipase, ribonuclease (RNase), and deoxyribonuclease (DNase I, II) in the serum were determined for 48 h after the development of pancreatitis. Amylase and lipase levels rose directly in both pancreatitis groups. These enzymes in the necrotizing pancreatitis group were higher than those in the edematous pancreatitis group, but there was no significant difference. RNase levels also rose markedly, but there was no obvious difference between either of the pancreatitis groups. On the other hand, DNase levels were high in the necrotizing pancreatitis group but low in the edematous pancreatitis group, with significant differences between the two groups, especially in the DNase II levels over a 36-h period (p less than 0.05-0.01). Therefore, these results suggest that serum DNase levels reveal the necrotizing changes in pancreatic parenchyma.

Changes in serum and intrapancreatic enzyme content and protein synthesis in pancreas were studied in acute oedematous pancreatitis (AOP). Male Wistar rats (n = 111) were divided into 2 groups, controls with a sham operation and those with AOP. Serum amylase levels rose immediately after the procedure causing AOP and then fell gradually, while serum lipase and ribonuclease levels remained higher than control values over 48 h. (p < 0.05, 0.01). Serum deoxyribonuclease (DNase) II levels were unchanged. Intrapancreatic enzyme levels were scarcely affected by AOP. 3H-leucine uptake into pancreatic tissue of rats with AOP was decreased throughout the study (p < 0.001), but some protein synthesis continued. Intrapancreatic enzyme contents are maintained despite diffusion into the blood because the pancreas retain its ability to synthesize enzymes.

The acute pancreatitis is still serious diagnostic and therapeutic problem. In spite of many experiments there are no satisfactory methods of the treatment of this disease. Usually, it is diagnosed clinically by acute abdominal pain and increased pancreatic enzymes in blood and urine. The main disorder of this disease is the necrosis of the pancreatic gland. The aim of our investigations was the evaluation of effect of necrolytic enzymes on the course of acute experimental pancreatitis. Fibrolan was used. Fibrolan (Parke-Davis) is a preparation, which has necrolytic properties. It consists of two bovine enzymes: fibrinolysin and deoxyribonuclease. The examinations were carried out on 380 Wistar rats. The acute pancreatitis was induced by retrograde injection of 0.1 ml/0.1 kg body weight of 3% sodium taurocholate solution into the pancreatic duct as previously described by other authors. The experimental animals were divided into four groups: K0-control group (healthy animals), KP-animals with acute experimental pancreatitis without medication, S-rats with acute experimental pancreatitis, which were treated with 0.9% NaCl solution, and F-animals with acute experimental pancreatitis treated with Fibrolan. Fibrolan and 0.9% NaCl were injected into the peritoneal cavity three times a day with eight hours intervals from the 24th experimental hour. The serum amylase and lipase activities and the amylase activity in the urine were determined in each animal group in the 24th, 48th, 72nd, 96th, 120th, 144th experimental hour. For histopathological analysis pancreatic tissue samples were taken from the pancreatic gland. The intensification of the histological changes of these tissue samples was judged using a point score as described by Spormann et al. The results were statistically analysed. The animals of the KP group showed significant histological changes of the pancreas during the whole examination time. Point score: 75-100. Microscopically, tissue samples taken from the animals treated with Fibrolan showed less changes from the 72nd examination hour. There were observed regenerative processes and the improvement of the histological state was evident (point score: 0-50). Changes were less in rats treated with 0.9% NaCl solution than in KP group but the regenerative processes were slower than in F group (point score: 50-75). Enzymes levels were significant lower in F group than in others from the 48th experimental hour.
