Changes in plasma nitric oxide metabolites concentration during glucose tolerance test in type 2 diabetic rats
Introduction: Repeated hyperglycemia play an important role in the development of atherosclerosis in diabetic patients. Endothelium is the organ of the first-line defense against atherosclerosis and nitric oxide has a major role in this task. The aim of this study was to determine changes in plasma nitric oxide metabolites concentration during glucose tolerance test in type 2 diabetic rats. Me...
متن کاملMacula densa neuronal nitric oxide synthase.
In the juxtaglomerular apparatus of the kidney the distal tubule returns to its own glomerulus where specialised cells, the macula densa (MD) cells, are located so that they come in contact with the tubular fluid. It is well documented that MD cells sense the distal tubular flow-rate and that when the flow is too high they are activated, which leads to vasoconstriction of the afferent arteriola...
متن کاملMacula densa basolateral ATP release is regulated by luminal [NaCl] and dietary salt intake.
One component of the macula densa (MD) tubuloglomerular feedback (TGF) signaling pathway may involve basolateral release of ATP through a maxi-anion channel. Release of ATP has previously been studied during a maximal luminal NaCl concentration ([NaCl](L)) stimulus (20-150 mmol/l). Whether MD ATP release occurs during changes in [NaCl](L) within the physiological range (20-60 mmol/l) has not be...
متن کاملLuminal NaCl delivery regulates basolateral PGE2 release from macula densa cells.
Macula densa (MD) cells express COX-2 and COX-2-derived PGs appear to signal the release of renin from the renal juxtaglomerular apparatus, especially during volume depletion. However, the synthetic machinery and identity of the specific prostanoid released from intact MD cells remains uncertain. In the present studies, a novel biosensor tool was engineered to directly determine whether MD cell...
متن کاملCompensatory ovarian changes, mast cell distribution and luminal structure changes following unilateral ovariectomy in rats
To follow-up the present study, 40 mature female rats were used. The animals were divided into test,control and sham groups. The rats in the test group were laparotomized and unilateral ovariectomy was done. On the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. The intact ovary in the test group underwent a significant (P
