11) One explanation has been found in immunocytochemical analyses of renal biopsies which have shown complete absence of H-ATPase pumps in the intercalated cell of the collecting tubules
which is largely responsible for proton secretion.
The ureteric bud divides and branches forming the renal pelvis, infundibulae, calyces, and collecting tubules
, which will provide a conduit for urine drainage in the mature kidney.
The cortical tubules mainly consisted of proximal and distal convoluted tubules together with collecting tubules
Colon and collecting tubules
connection should be drained separately.
Submucosal proventricular glands, consisting of secretory units and collecting tubules
, occupied parts of the choristomal wall.
Kidneys show subcapsular cysts, representing ectasia of the collecting tubules
41) Histologically there is diffuse acute tubular injury accompanied by uric acid crystals located predominantly in the collecting tubules
Although many hormones exert tissue-specific effects through specific receptor interactions, the mineralocorticoid receptor in the renal collecting tubules
binds cortisol and aldosterone with equally high nanomolar affinity in vitro.
Flowdependent potassium secretion by rabbit cortical collecting tubules
The article should have stated that AVP antagonists decrease water permeability of renal collecting tubules
, thereby promoting excretion of retained water and normalizing hypo-osmolar hyponatremia.
Homeostatic control of sodium excretion is achieved via changes in sodium reabsorption in the late distal and collecting tubules
There were very largely dilated collecting tubules
and ducts with granular degeneration & sloughing out of lining epithelia.
