A nondopaminergic antipsychotic agent, 5-ethyl-1,3,8-trimethyl-1H-imidazo]1,2-c]pyrazolo[3,4-e]pyrimidine (TIPP; PD 112488), has been tested for potential toxicity in rats. As part of a preclinical safety evaluation, 10 Wistar rats per sex were administered TIPP as a dietary admixture, receiving doses of 0, 5, 10, 20, 25, 50, 100, and 200 mg/kg for 2 wk. In addition, 3 groups of 6 male Wistar rats were administered TIPP (PD 114877 and PD 117498, acid hydrolysis products of TIPP) at 100 mg/kg by gavage for 5 days. All animals given 200 mg/kg were euthanatized in moribund condition or found dead after 1 wk of treatment. Clinical evidence of renal toxicity was noted and included emaciation, hematuria, urinary incontinence, and enlarged kidneys at doses of 10 mg/kg and higher. Plasma urea levels were higher than those of controls in all TIPP-treated groups. Significant pathologic changes of the urothelium were evident at all doses and were characterized by necrotizing pyelitis and cystitis. Necrosis and inflammation of the urothelium resulted in secondary hydronephrosis. No renal toxicity was noted with the acid hydrolysis products. The urothelial changes with oral administration of TIPP in rats is species-specific, and the specificity may be related to the metabolism and excretion of the drug.

Hydronephrosis occurs as a congenital or an acquired condition following obstruction of the urinary tract. In this study, a four month old male Holstein calf with emaciation, growth retardation and a poor dry scruffy hair coat was examined because of remarkable distention of right abdomen. At necropsy, right kidney was hydronephrotic as a very big fluid-filled round pelvis with the presence of multilocular cysts bulged from the cortical surface. With sectioning, more than 10 L of bloody fluid poured out from this sac. Microscopic examination showed severe atrophy of cortical tissue and fibrosis of the medulla. Also, the dilated pelvis was composed of fibrinous exudate and necrosis of epithelium associated with multifocal aggregations of neutrophils and bacterial microcolonies. In a culture and serotyping of isolated bacteria, Salmonella dublin was determined. In conclusion, S. dublin induced pyelonephritis secondary to congenital giant hydronephrosis is the first report in cattle in the world.
