At the early stages of diabetes preceding the appearance of morphological changes, certain changes such as an increased renal plasma flow, intraglomerular
hydrostatic pressure, and glomerular filtration rate become manifest.2 These changes may appear due to a wide variety of factors that result from high glucose-induced interactions between a group of metabolic and hormonal.
The most consistent lesions were tubulonephrosis with occasional tubular epithelium necrosis; intraglomerular
urolithiasis and multifocal interstitial lympho-histiocytic infiltration (Figure 7, panel A); vacuolic degeneration and disintegration of liver cells with signs of hepatitis (Figure 7, panel B); acute serous myocarditis; and depletion of lymphocytes with scattered lymphocyte necrosis in the lymphoid organs (spleen, bursa Fabricii, and thymus) (Figure 7, panels C and D).
"This suggests that the mechanism of benefit is likely to be independent of glucose levels and may possibly stem from a reduction in intraglomerular
pressure, with other possible mechanisms presently being studied."
What is the significance of CD34 immunostaining in the extraglomerular and intraglomerular
Solitary kidney post nephrectomy, has been the most frequent and common causes of secondary FSGS, and adaptive response occurred in such cases because of reduced renal mass leading to compensatory intraglomerular
hypertension and hypertrophy in the remaining glomeruli7, ultimately leading to FSGS over a period of years and this effect is dose dependent with greater risk of developing proteinuria, glomerulosclerosis and progressive renal failure in those patients who lost greater than 75% of renal mass8.
and extraglomerular BMP-7 protein expression were higher in kidney of telmisartan-induced Wistar rats than negative control.
Glomus body consists of afferent arteriole, anastomotic vessel known as SucquetHoyer Canal, primary collecting vein, intraglomerular
reticulum and capsular portion.
These medications are considered superior to other categories of antihypertensive medications in the treatment of DN due to their capacity to reduce the intraglomerular
pressure and prevent proteinuria by favoring the dilation of the efferent glomerular arteriole.

Finally, several authors have hypothesized that CAN is indirectly involved in the pathogenesis of diabetic nephropathy, via hemodynamic changes such as lack of nocturnal BP dipping (causing increased intraglomerular
pressure resulting in albuminuria) and diurnal postural falls in BP (resulting in lower intraglomerular
pressure) and endothelial dysfunction .
Perivascular epithelioid cell tumors (PEComas) of the kidney are a group of tumor family covering classical angiomyolipoma (AML), microscopic AML (microhamartoma), intraglomerular
lesions, cystic AML, epithelioid AML, oncocytoma-like AML and lymphangiomyomatosis of the renal sinus.
