3.2 pancreas hydroxyproline contents measure
At the end of experiment, carry out pulmonary's hydroxyproline content mensuration to each group of rat, result is as table 2.Compositions, on the impact of hydroxyproline content, compares with model group and has significant difference.Compound III and compound IV, on the impact of hydroxyproline content, compare there was no significant difference with model group.
Table 2
* represent p<0.05, compare with model group
3.3 histological examination
At the end of experiment, rat put to death, dissect; The embedding of specimen routine, fixing, HE dyeing, microscopy.
Result: model group visible pancreas surrounding catheter extensive inflammation reaction in the 60th day; Addicted to middle granulocyte karyolymph cellular infiltration, interstitial edema, hemorrhage and accidental pancreas cystencyte is downright bad; Fibrosis is there is between pancreas cystencyte disappearance position and pancreas bubble.
Compositions can reduce inflammatory reaction and fibrosis.Appraisal result is in table 3.Compositions, on the impact of scoring, compares with model group and has significant difference.
Table 3
* represent p<0.05, compare with model group; The inflammatory cell infiltration of blank group and Fibrosis score are all 0.
