[A case of domestic violence-related Page kidney].

Page kidney is caused by the accumulation of blood in the perinephric or subcapsular space, resulting in compression of the involved kidney, renal ischemia and high renin hypertension. We describe a case of domestic violence-related Page kidney. This report also reviews previously described cases of Page kidney.

[A case of renal cell carcinoma producing alpha-fetoprotein].

Renal cell carcinoma (RCC) producing alpha-fetoprotein (AFP) is a rare condition with only 11 cases reported in Japan to our knowledge. A 69-year-old man was admitted to our hospital for further examination of an incidental right renal tumor. Laboratory tests showed markedly increased serum level of AFP whereas both HBs antigen and anti-HCV antibody were negative.

Strain variation in renal carcinogenesis by N-ethyl-N-hydroxyethylnitrosamine in F1 (Wistar-Fischer) rats.

The present study was conducted to compare the incidences of renal tumors in Wistar (W), Fischer (F) and F1 rats (WF: female Wistar rats x male Fischer rats; FW: female Fischer rats x male Wistar rats) induced by N-ethyl-N-hydroxyethylnitrosamine (EHEN). Levels of 8-OHdG in renal DNA were also investigated in Wistar and Fischer rats. After 2000 ppm of EHEN was administered orally for 2 weeks, the animals were fed basal diet until week 32.
