con·vo·lu·ted tu·bule

(kon'vŏ-lūt'ĕd tū'byūl)
Either of the two intricately coiled segments of the renal tubule; the proximal convoluted tubule leads from the capsule of the kidney to the straight portion of the proximal tubule; the distal convoluted tubule is formed from the ascending limb of the loop of Henle and ends in a collecting tubule.

Also, comparing to the control animals, we revealed the increasing of the average size of epithelian cells of the proximal convoluted tubule in 9.
The opening of the proximal convoluted tubule is 10.
This, first of all, is expressed in the form of expanding of the renal corpuscle and glomerulus size, change of the size of proximal convoluted tubule opening.
Interestingly, the reversion of the damage was associated with a higher regenerative activity (PCNA immunostaining) in the kidney of animals treated with curcumin as complete treatment or a posttreatment; this activity was specifically observed in the epithelium from the convoluted tubules distant to the surgical scar.
The VP40 antigen also localized in the epithelial cells lining the proximal convoluted tubules of the kidney.
A peculiar finding in our study was that epithelial cells of the renal proximal convoluted tubules of NHP and guinea pigs contained VP40 antigen, yet they did not appear to be infected with the virus.
