Immunohistochemical expression of intrarenal renin angiotensin system components in response to tempol in rats fed a high salt diet

Figure 5 The graphs show the quantitative evaluation of angiotensin type 1 receptor immunostaining in renal tissue. Data are expressed as mean ± SEM; ^aP < 0.05 vs the respective NS group, ^cP < 0.05 vs the respective group without tempol. The photomicrographs represent AT1R immunostaining in NS, HS, NS-T and HS-T groups. Original magnification: 400 ×. IOD: Integrated optic density; NS: Normal salt diet group; HS: High salt diet group; NS-T: Normal salt diet plus tempol group; HS-T: High salt diet plus tempol group; AT1R: Angiotensin type 1 receptor.
