This study examined the effects of inhibiting Cu/Zn superoxide dismutase with diethyldithiocarbamate (DETCA) on the ability of superoxide generating agents such as pyrogallol, hypoxanthine/xanthine oxidase and LY 83583, to influence NANC relaxation of strips of bovine retractor penis (BRP) muscle. Although pyrogallol (100 microM) and hypoxanthine (0.3(More)
BACKGROUND Monoamine reuptake inhibitors exhibit unique clinical profiles that reflect distinct engagement of the central nervous system (CNS) transporters. METHODS We used a translational strategy, including rodent pharmacokinetic/pharmacodynamic modeling and positron emission tomography (PET) imaging in humans, to establish the transporter profile of(More)
Transplacental induction of lung tumors in C3HfeB/HeN (C3Hf) strain mice can be readily achieved with the carcinogen 1-ethyl-1-nitrosourea. Several of these tumors express, as a tumor-associated transplantation antigen (TATA), a normal tissue alloantigen present in strain A and C3H/HeN (C3H) mice. In the present study it was shown that the tumor-associated(More)
Hydroxocobalamin inhibited nitrergic nerve-induced relaxations in rat anococcygeus and bovine retractor penis muscles in a concentration-dependent manner. In the rat anococcygeus muscle, the inhibition was greater in light than in dark conditions, whereas in the bovine retractor penis the inhibition was similar under both conditions.
