Bowman’s Capsule


(named after the 19th-century English physician W. Bowman), a cuplike cul-de-sac of the uriniferous tubule of the kidneys of vertebrate animals and humans. Bowman’s capsule surrounds the glomerulus and together they form the malpighian body. The wall of Bowman’s capsule consists of an inner and outer layer, between which is a gap—the cavity of Bowman’s capsule—lined with a flat epithelium. The inner layer adheres to the glomerulus, and the outer layer becomes the beginning of the uriniferous tubule. In Bowman’s capsule, so-called primary urine is formed.

Biochemical and histopathologic investigations of this study indicated that prostodin caused increased blood serum creatinine and urea and Bowman capsule diameter, decreased urinary space, as well as glomerular dilation (glomerular hypertrophy), resulting in disorder in renal function, lack of proper blood treatment, and finally further increase in serum creatinine.
A portion of the glomeruli demonstrated segmental adhesions of the glomerular tuft to the Bowman capsule. CD68 immunohistochemistry revealed lipid-storing macrophages (A, inset).
(11) The lesions seen in diabetic nephropathy that are represented as hyalinosis of the glomerular capillary tuft, arterioles, and capsular drops localized on the inner aspect of the Bowman capsule have been described in the literature as insudative lesions because they include blood-derived proteins, such as IgM and C1q.
We define periglomerular fibrosis as glomeruli with open capillaries, but lamellated, frequently wrinkled, Bowman capsular basement membrane and circumferential layers of interstitial-type collagen around, within, or between the usually thickened, frequently lamellated, Bowman capsule basement membrane (Figure 2).
