Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate Mgr. Renata Veselá Supervisor Prof. Ing. Vladimír Wsól, Ph.D. Title of Doctoral Thesis On Purinoceptors in the Rat Urinary Bladder Both divisions of autonomic nervous system regulate the urinary bladder function. In addition to the classical autonomic neurotransmitters, noradrenaline and acetylcholine, other autonomic transmitters and signalling molecules play important roles in the physiology and pathophysiology of the lower urinary tract. Interstitial cystitis (IC) is a chronic inflammation of the bladder of non-infectious origin and unclear etiology and pathophysiology, characterized by urinary frequency, urgency and sharp pelvic pain that fade away while urinating. Non-adrenergic, non-cholinergic (NANC) systems influence functional responses in the inflamed bladder. The aim of this study was to investigate purinergic and nitrergic mechanisms involved in the IC pathogeneses and in urodynamic dysfunction. Methods: A single dose of i.p. injection of cyclophosphamide caused CYP-induced cystitis; a condition very similar to IC and for that property was used as a model of the inflamed bladder throughout our experiments. The organ bath set was employed in investigation of functional...
