Diabetes mellitus was tentatively diagnosed in a black-footed ferret with polyuria, polydipsia, polyphagia, dehydration, and weight loss. Laboratory findings (marked hyperglycemia (724 mg/100 ml), glycosuria, and ketonuria) and the subsequent favorable response to insulin therapy confirmed the diagnosis. Although lesions were not observed in the pancreas, gross and histologic findings concomitant with diabetes mellitus included arteriosclerosis, with calcification of the aorta and other major vessels; mild necrotizing hepatitis; and mild proliferative glomerulonephritis. A perineal adenocarcinoma, with metastasis to an internal iliac lymph node, was an incidental finding. Special stains demonstrated adequate numbers of beta cell granules in the islets of Langerhans. Thus, the diabetes was apparently due to a lack of release of the synthesized insulin or to diminished effectiveness of the secreted insulin.

Polymorphisms that have been proven to influence gene functions are called functional polymorphisms. It is significant to know the distribution of functional polymorphisms in the rat, widely used in animal models for human diseases. In this study, we assessed 16 functional polymorphisms consisting of 3 coat color and 13 disease-associated genes in 136 rat strains, as a part of the genetic profiling program of the National Bio Resource Project for the Rat (NBRP-Rat). Polymorphisms of Cdkn1a, Fcgr3, Grp10, Lss, and Fdft1, which were proven to function in prostate tumorigenesis, glomerulonephritis, hyperphagia, and cholesterol biosynthesis, were shared among various inbred strains. These findings indicated that most rat strains harbored the disease-associated alleles and suggested that many unidentified functional polymorphisms might exist in inbred rat strains. The functional polymorphisms shared in inbred strains were also observed within outbred stocks available commercially. Therefore, this implies that experimental plans based on either rat inbred strains or outbred stocks need to be carefully designed with a full understanding of the genetic characteristics of the animals. To select the most suitable strains for experiments, the NBRP-Rat will periodically improve and update the genetic profiles of rat strains.

A 59-year-old woman was admitted to our hospital for treatment of acute renal insufficiency. She had been under home intravenous hyperalimentation therapy through a totally implantable central venous catheter for 2 years because of post-radiation enteritis. Clinical examination on admission revealed severe renal insufficiency complicated with hypocomplementemia, marked proteinuria and hematuria. Chest roentgenography demonstrated moderate pulmonary congestion. Hemodialysis was initiated and her pulmonary congestion improved. On the 14th and 21st hospital day, blood culture revealed Staphylococcus epidermidis colonization. Cefazolin was administered and C-reactive protein decreased, however, renal insufficiency and hypocomplementemia did not improve. To investigate the genesis of renal insufficiency, renal biopsy was performed. Light microscopic findings of the kidney revealed severe crescentic glomerulonephritis complicated with moderate tubulointerstitial damage. Immunofluorescence-microscopic findings of the kidney revealed positive IgG, IgM, C3 deposition along the capillary lumen. From these laboratory findings and the clinical course, we diagnosed her renal disease as crescentic glomerulonephritis induced by catheter-related bloodstream infection, and the central venous catheter was removed. After removal, urinary output and hypocomplementemia remarkably improved, however, unfortunately, her renal dysfunction did not improve and maintenance hemodialysis needed to be continued. Although her renal disease was not caused by ventriculo-atrial shunt but by central venous catheter-related bloodstream infection, we supposed that the pathogenesis was a closely similar entity to shunt nephritis.
