Effect of hypertonic saline on systemic inflammatory response in rat with severe acute pancreatitis / 中国普通外科杂志

ABSTRACT

Objective To investigate the effect of hypertonic saline in the management of murine experimental severe acute pancreatitis (SAP) Methods SAP was induced in Wistar rats by intraperitoneal injection of 20% L Arginine Rats were divided into four groups ( n =12 in each group ); Healthy controls received intraperitoneal injection of distilled water of 5 ml/kg body weight initially Rats in the four groups were infused at 24 h and 48 h respectively at a dosage of 2 ml/kg body weight of distilled water in both healthy contrals, and SAP controls, of normal saline in group 3 and of hypertonic saline (7 5% sodium chloride) in group 4 Blood samples were collected at 48 h and 72 h after last injection for the measurement of plasma TNF ?、IL 6、 IL 10 All rats were sacrificed for histopathology of pancreatic and lung tissues at 72 h Results Animals that received hypertonic saline showed less pancreatic and lung damage than those resuscitated with normal saline Plasma levels of TNF ?、 IL 6 decreased significantly and plasma levels of IL 10 increased more significiently at 72 h after induction of SAP Conclusion Hypertonic saline resuscitation result in a significant attenuation of the systemic inflammatory response to severe acute pancreatitis
