Pathological symptoms such as for example glomerulosclerosis, tubulointerstitial fibrosis, improved systolic blood circulation pressure, reduced creatinine clearance, and improved albumin-to-creatinine ratios in DSH rats had been alleviated by “type”:”entrez-nucleotide”,”attrs”:”text message”:”CG200745″,”term_id”:”34091806″,”term_text”:”CG200745″CG200745 treatment compared to those manifestations in positive control animals. Furthermore, this treatment counteracted the increased expression of SMA, TGF-1, and Bax, and the decreased expression of Bcl-2 in the kidneys of DSH rats. It also attenuated the increase in the number of apoptotic cells in DSH rats. Thus, “type”:”entrez-nucleotide”,”attrs”:”text”:”CG200745″,”term_id”:”34091806″,”term_text”:”CG200745″CG200745 can effectively prevent the progression of renal injury in DSH rats by exerting anti-inflammatory, anti-fibrotic, and anti-apoptotic effects. 0.05, when DHS or DSH + “type”:”entrez-nucleotide”,”attrs”:”text”:”CG200745″,”term_id”:”34091806″,”term_text”:”CG200745″CG200745 groups were compared to control group. 0.05, when DSH + “type”:”entrez-nucleotide”,”attrs”:”text”:”CG200745″,”term_id”:”34091806″,”term_text”:”CG200745″CG200745 group was compared to DSH group. Table 2 summarizes renal function changes among the groups. Serum creatinine tended to be increased in DHS rats, but this effect did not reach statistical significance. Further, the fractional excretion of sodium was significantly elevated in DSH rats, suggesting impaired tubular sodium reabsorption. In addition, the albumin-to-creatinine ratio was markedly increased in DSH rats, which was attenuated by “type”:”entrez-nucleotide”,”attrs”:”text”:”CG200745″,”term_id”:”34091806″,”term_text”:”CG200745″CG200745 treatment.
