Characteristics of models of pancreatitis induced by Na-TC in different species
Dose | Species | Effect | Reference(s) |
---|---|---|---|
10%, 1.0 ml/kg | Dog | Significantly increased serum and ascites amylase, lipase levels; pancreatic parenchymal oedema, inflammatory cell infiltration and necrosis; other organ injury: N/A | 64 |
5%, 1.0 ml/kg | Rabbit | Pancreatic oedema, inflammatory cell infiltration, necrosis, haemorrhage and fat necrosis; other organ injury: N/A | 62 |
20%, 1.0 ml/kg | Pig | Significantly increased serum lipase level, WBC counts and neutrophils; significantly decreased mean blood pressure, serum lymphocytes and platelets; pancreatic oedema, haemorrhage, necrosis and accumulation of neutrophils, lymphocytes and macrophages; other organ injury: N/A | 66 |
5%, 0.5 ml/kg plus 5% trypsin | Pig | Significantly increased serum amylase and WBC counts; focal liquefactive necrosis in most of the pancreas, with neutrophil infiltration; other organ injury: N/A | 63 |
3–5%, 1.0 mg/kg | Rat | Significantly increased serum amylase, lipase and proinflammatory cytokine levels; pancreatic oedema, vacuolization, inflammation, haemorrhage, acinar cell and fat necrosis; lung, liver, gastric, kidney and brain injuries | 67–72,74,123–125 |
2%, 50 µl | Mouse | Increased serum amylase and IL-6; transient increase of intrapancreatic trypsin activity; pancreatic oedema, leukocyte infiltration and necrosis; no mortality | 82 |
4%, 5%, 2.0 ml/kg | Mouse | Increased serum amylase, lipase and IL-6; decreased serum IL-12; pancreatic oedema, leukocyte infiltration, necrosis, haemorrhage and fat necrosis; increased pulmonary BAL fluid albumin and MPO activity; 10% and 60% mortality rates at 24 h for 4% and 5% Na-TC, respectively | 85 |
