Research Interests   In the first year of my Ph.D I have used the patch clamp technique to characterise the T and L type calcium current in isolated rabbit urethra smooth muscle cells. I have shown their voltage dependence, selectively blocked each current then showed the effect of selectively blocking each current on the spontaneous activity generated in the urethra.
Currently I am using microflurimetry to demonstrate capacitative calcium entry in isolated urethra cells. I hope to show its selective block with pharmacological agents such as SKF-96365, Lanthanum and Gadolinium. When I have been able to selectively block the capacitative entry pathway I would then like to discover (using the patch clamp technique) how blocking this pathway affects the spontaneous activity in these cells.   Publications   Bradley E, Law A, Bell D, Johnson CD.
