Objective:
To observe the alteration of both inflammatory and anti-inflammatory cytokines during acute pancreatitis, and to investigate the effect of somatostatin on modulation of inflammatory and anti-inflammatory cytokines in experimental acute pancreatitis.
Methods:
SD male rats were divided into 3 groups: group 1. the normal rats as control (n = 6); group 2, the rats with acute pancreatitis induced by transabdominal injection of 5% sodium cholate sulfur (at the volume of 1.0 ml/kg) into the parcreatic duct and not given drug treatment; group 3, the rats injected with stilamin 20 micrograms/kg, intravenously, 30 minutes after the successful induction of acute pancreatitis. The animals in groups 2 and 3 were killed at 2, 6 and 24 hours after operation. The blood samples were taken for measurement of IL-1, TNF alpha, IL-6 (by Bioassay) and IL-10, TNF-beta (by ELISA). The wet weight of pancreatic tissue and amylase were also determined.
Results:
Serum IL-1, TNF alpha, IL-6, IL-10 and TGF-beta in control group were 0.56 +/- 0.06 ng/ml, 23.50 +/- 1.87 IU/ml, 69.0 +/- 6.40 IU/ml, 32.05 +/- 14.87 pg/ml and 66.4 +/- 13.20 pg/ml, respectively. After acute pancreatitis was induced, the serum level of these inflammation-concerned cytokines increased significantly in group 2 (P < 0.05). Serum IL-1, TNF alpha, IL-6, IL-10 and TGF-beta in group 2 at 24 hours after pancreatitis were 1.15 +/- 0.13 ng/ml, 55.33 +/- 12.79 IU/ml. 127.17 +/- 13.91 IU/ml, 68.13 +/- 19.90 pg/ml, and 103.77 +/- 28.95 pg/ml, respectively. After administration of somatostatin, the inflammation-concerned cytokines in group 3 were remarkably decreased (P < 0.05). Serum IL-1, TNF alpha, IL-6, IL-10 and TGF-beta in group 3 were 0.83 +/- 0.12 ng/ml, 33.00 +/- 7.40 IU/ml. 71.83 +/- 6.34 IU/ml, 42.2 +/- 14.55 pg/ml, and 45.98 +/- 18.10 pg/ml, respectively. The indeies of the severity of pancreatitis, such as amylase and the weight of pancreas alse improved in group 3.
Conclusion:
Both inflammatory and antiinflammatory cytokines increased remarkably in the rats with acute pancreatitis. This result indicates that there is a potential tendency of inflammatory response syndrome and compensatory anti-inflammatory response syndrome in the course of acute pancreatitis. Somatostatin can modulate the derangement of these cytokines in acute pancreatitis.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
