3 results
Influence of 3.1 compositions to rat pancreas organ coefficient
At the end of experiment, rat is put to death, dissected, weighed in and its ratio (pancreas with body weight is weighed and calculated with pancreas
Organ coefficient), the results are shown in Table 1.Influence of the composition to pancreas organ coefficient, comparing with model group has significant difference.Chemical combination
The influence of thing III and compound IV to pancreas organ coefficient, compares that there was no significant difference with model group.
Table 1
* p is represented<0.05, compare with model group
3.2 pancreas hydroxyproline contents are determined
At the end of experiment, lung's hydroxyproline content measure is carried out to each group rat, as a result such as table 2.Composition is to hydroxyl dried meat
The influence of histidine content, comparing with model group has significant difference.Shadows of the compound III and compound IV to hydroxyproline content
Ring, compare that there was no significant difference with model group.
Table 2
* p is represented<0.05, compare with model group
3.3 histological examinations
At the end of experiment, rat is put to death, dissected;Sample routinely embedding, fixed, H` dyeing, microscopy.
As a result:Model group visible pancreas surrounding catheter extensive inflammation reaction in the 60th day;Thermophilic middle granulocyte karyolymph cellular infiltration,
Interstitial edema, bleeding and the necrosis of accidental pancreas cystencyte;There is fibrosis between steeping in pancreas cystencyte disappearance position and pancreas.
Composition can reduce inflammatory reaction and fibrosis.Appraisal result is shown in Table 3.Influence of the composition to scoring, with model
Group compares significant difference.
Table 3
* p is represented<0.05, compare with model group;The inflammatory cell infiltration and Fibrosis score of blank control group are all 0.
Conclusion:The present invention passes through influence of the composition to pancreas in rat fibrosis, it was confirmed that composition has anti-pancreas fine
The effect of dimensionization.Therefore, composition can be used to prepare the medicine of anti-pancreatic fibrosis as active component.And compound III and
Compound IV is without this activity, it is impossible to the medicine for preparing anti-pancreatic fibrosis.
