At the end of the experiment, the kidney tissue of the mice was taken and the results of the inflammation-related proteins were analyzed by Western blotting.

The results of Fig. 16 and Fig. 17 showed that the protein expressions of the inflammatory related proteins COX-2, NF-κB and iNOS were increased by 7.56, 4.34 and 4.49 times, respectively, compared with the control group, which reached statistically significant differences. In the experimental group, the protein expression of NF-κB and iNOS increased by 1.41 and 1.28 times, respectively, in the adenine 0.2%+AV 1%+PK 1% test group compared with the induction group, and the increase of NF-κB was significantly different. Compared with the induction group, the adenine 0.2%+AV 2%+PK 1% test group can significantly reduce the protein expression of proinflammatory cytokines COX-2, NF-κB and iNOS, which are reduced to 0.5 and 0.74 in the induction group, respectively. 0.2 times, a statistically significant difference. Compared with the induction group, the expression of iNOS protein in adenine 0.2%+AV 2% test group was significantly reduced to 0.38 times that of the induction group. There was no statistical difference in COX-2 and NF-κB protein expression. Compared with the induction group, the adenine 0.2%+PK 1% test group showed a significant increase in COX-2 protein expression, an increase of 1.05 times. Although there was an increasing trend in NF-κB and iNOS, it did not reach statistically significant difference. Therefore, the aloe porcine kidney compound composition can significantly reduce the expression of COX-2, NF-κB and iNOS protein and have a multiplication effect.
