【Abstract】Objective To study the liver injury and effects of aescin on liver in rats with acute pancreatitis. Methods The rats were divided into 3 groups (control group, AP group and aescin group). The serum alanine aminotransferase （ALT）, serum lactate dehydrogenase (LDH), hepatic cellular energy charge (EC) and adenosine triphosphate (ATP) were detected. The pathologic changes in pancreas and liver were also observed. Results The serum levels of ALT and LDH in aescin group were significantly lower than those of the AP group. The EC and ATP levels were significantly higher in aescin group than that of the AP group. Conclusion Introvenous injection of aescin can alleviate the liver injury in rats with acute pancreatitis.
【Abstract】ObjectiveTo study the expressions of P-gp, nm23 and p53 in primary breast cancer tissues and to evaluate the prediction significance in recurrence of the primary breast cancer. MethodsExpressions of P-gp, nm23 and p53 in 57 benign and malignant breast paraffin-embedded specimens, the difference of the rate and intensity of positive reaction of P-gp,nm23 and p53 were checked by immunohistochemical staining.ResultsThe positive rate of nm23 significantly increased in benign breast tissues compared with the tissues of recurrence of breast cancer. The positive intensity of nm23 was significantly decreased in the tissues of recurrence of breast cancer compared with the tissues of primary breast cancer. The positive rate of p53 was significantly increased in malignant breast tissues compared with benign breast tissues. The positive intensity of p53 was significantly increased in the tissues of recurrence of breast cancer compared with the tissues of primary breast cancer. There was no difference in the positive rate of P-gp in the tissue of recurrence and primary of breast cancer compared with benign breast tumor. But the positive intensity of P-gp was significantly decreased in the tissues of recurrence and primary of breast cancer compared with benign breast tumor. ConclusionThe expression of p53 may indicate the proliferating activity of carcinoma cell. The positive intensity of expression of p53 and nm23 is valuable in prediction of the recurrence of primary breast cancer.
