1. Studies of nucleotide receptors-induced calcium response in glomerular mesangial cells and afferent arterioles
Sammanfattning : It is known that intracellular calcium concentration ([Ca2+]i) changes in rat glomerular mesangial cells (GMC) and rabbit afferent arterioles (AA) in response to extracellular nucleotides. We studied the nucleotide-induced calcium response in cultured GMC and AA. LÄS MER
Sammanfattning : Renal arterioles represent the most important effecter site in the control of renal perfusion and filtration. Adenosine (Ado), angiotensin II (Ang II) and nitric oxide (NO) interact in modulating arteriolar tone. The present work investigates the mechanism of this interaction. LÄS MER
3. Calcium Responses in the Renal Afferent Arteriole to Angiotensin II and Norepinephrine Stimulation
Sammanfattning : Studies were performed to investigate the influence of the vasoconstrictors angiotensin II (AII) and norepinephrine (NE) on calcium metabolism in smooth muscle cells of afferent arterioles. Fura-2 and image analysis techniques were used to evaluate calcium responses in the proximal and distal parts of afferent arterioles with attached glomeruli. LÄS MER

Sammanfattning : Local control of regional blood flow is exerted mainly through the arterioles. An adequate minute-to-minute regulation of blood perfusion of the kidney and the pancreas is obtained by the modulation of arteriolar reactivity, which will influence the organ function. LÄS MER
