Abstract:
Objective To explore whether intravenous injection of hydrogen‐rich saline having the protective effect on sodium taurocholate induced severe acute pancreatitis(SAP) associated lung injury(APALI) in rats and its possible mechanisms .Methods Fifty‐four healthy male SD rats were randomly divided into sham‐operation group (Sham group) ,model group (SAP+ NS group) and hydrogen water treatment group (SAP + HRS group) ,and each group was subdivided into 6 ,12 ,24 h subgroups .Six rats were killed at each time point for collecting serum ,lung tissue and pancreas tissue .Serum TNF‐αand IL‐1βlevels ,lung wet /dry weight ratio ,expression of TNF‐αmRNA and IL‐1βmRNA in the lung tissue were detected .The pathological evaluation of pancreas and lung tissue injury was performed .Results (1)The levels of TNF‐α and IL‐1β in serum ,pancreas and lung tissue pathological scores ,TNF‐αmRNA and IL‐1βmRNA expression levels in the lung tissue and lung wet dry weight ratio at the time points of 6 , 12 ,24 h in the SAP+NS group and the SAP+ HRS group were higher than those in the sham group (P<0 .05) .(2) Compared with the SAP+NS group ,the levels of serum TNF‐α,TNF‐αmRNA expression level in the lung tissue and lung wet dry weight ra‐tio at all time points in the SAP+ HRS group were lower(P<0 .05);the levels of serum IL‐1β,pancreas and lung tissue pathologi‐cal score and IL‐1β‐mRNA expression at 6 h in the lung tissue had no statistical difference between the SAP+NS group and SAP+HRS group ,but which at time points of 12 ,24 h in the SAP+ HRS group were lower than those in the SAP+NS group(P<0 .05) . Conclusion HRS realize the protection on APALI possibly via its elective anti‐oxidation action for inhibiting oxidative stress injury related cytokines expression .
