متن کاملEthanol-mediated relaxation of guinea pig urinary bladder smooth muscle: involvement of BK and L-type Ca2+ channels.
Mechanisms underlying ethanol (EtOH)-induced detrusor smooth muscle (DSM) relaxation and increased urinary bladder capacity remain unknown. We investigated whether the large conductance Ca(2+)-activated K(+) (BK) channels or L-type voltage-dependent Ca(2+) channels (VDCCs), major regulators of DSM excitability and contractility, are targets for EtOH by patch-clamp electrophysiology (conventiona...
متن کاملPHEOCHROMOCYTOMA OF THE URINARY BLADDER
One of the rarest tumors involving the urinary bladder is the pheochromocytoma. A case of pheochromocytoma of the urinary bladder in a young female suffering from headache and cystitis for many years is reported. Twenty-four hour urine VMA was normal. The patient was never hypertensive except during surgical manipulation of the tumor. Biopsy of the bladder resulted in massive hemorrhage.
متن کاملThe effect of indomethacin on the muscarinic induced contractions in the isolated normal guinea pig urinary bladder
BACKGROUND To investigate the effect of prostaglandin depletion by means of COX-inhibition on cholinergic enhanced spontaneous contractions. METHODS The urethra and bladder of 9 male guinea pigs (weight 270-300 g) were removed and placed in an organ bath with Krebs' solution. A catheter was passed through the urethra through which the intravesical pressure was measured. The muscarinic agonist...
متن کاملNeurogenic Inflammation of Guinea-Pig Bladder
Capsaicin, substance P, and ovalbumin, instilled into the bladders of naive and ovalbumin (OVA) sensitized guineapigs caused inflammation, as indicated by increased vascular permeability. Histological changes after exposure to these compounds progressed with time from intense vasodilatation to marginalization of granulocytes followed by interstitial migration of leukocytes. In vitro incubation ...
