Objective To explore the influences of hydrogen sulfide (H2S) on acute necrotizing pancreatitis (ANP).
Methods Forty-three SD male rats were grouped by random number table, and divided into five groups:the sham group (n=4), ANP group 〔n=21, which was divided into 3 subgroups:3, 6, and 12 hours group (n=7)〕, NaCl+ANP group (n=4), NaHS+ANP group (n=7), and PAG+ANP group (n=7). Models of ANP were formed by
retrograde cholangiopancreatography injection of 5% sodium taurocholate. The NaCl+ANP group, NaHS+ANP group, and PAG+ANP group rats were given pretreatment of saline, NaHS, or PAG at 1 hour before modeling
respectively. The levels of serum amylase (AMY), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine (Cr) were detected, and the pathological histological changes of pancreatic tissues were observed.
Results The levels of serum AMY, AST, ALT, BUN, and Cr were increased in ANP group. The levels of serum AMY, AST, ALT, BUN, and Cr in the NaHS+ANP group were higher than those of NaCl+ANP group (P<0.05), and the pathological damage of the pancreatic tissues was more serious in the NaHS+ANP group. The levels of serum AMY, AST, ALT, BUN, and Cr in the PAG+ANP group were lower than those of NaCl+ANP
group (P<0.05), and the pathological damage of pancreatic tissues in the PAG+ANP group was not so serious as in the NaCl+ANP group.
Conclusions The impairment of liver, kidney, and pancreas function in ANP rats may be related to elevated H2S concentration. Prophylactic administration the PAG of H2S antagonist can improve the function of the liver, kidney, and pancreas, and have the effects of organ protection.
