Status and Perspective of the Blakiston’s Fish Owl Population, Based on Genetic Diversity
Blakiston’s fish owl (Bubo blakistoni) was formerly widespread on Hokkaido island, but its population size decreased during the twentieth century due to reduction and fragmentation of its habitat through human ac...

Hepatoma-Associated Alterations of Serum α1-Antitrypsin in LEC Rats
LEC rats have been established as a new mutant strain which develops hereditary hepatitis [1–3] and spontaneous hepatocellular carcinomas (hepatomas) [4]. However, the mechanisms of the development of the sequ...

Chromosomal Map** of the Placental Glutathione S-Transferase Gene and Its Expression in Livers of LEC Rats
The LEC strain rat is a new mutant which suddenly suffers from fulminant hepatitis at about 4 months of age [1, 2]. A crossing test of LEC rats showed that the hepatitis has an autosomal recessive mode of inhe...

Drug-Metabolizing Ability and Inducibility of Chromosomal Aberrations and Sister Chromatid Exchanges in LEC Rats Exposed to Cyclophosphamide
The LEC rat strain is a new mutant characterized by the spontaneous development of hepatitis with severe jaundice about 4 months of age [1, 2]. Genetic analysis demonstrated that the disease has an autosomal r...
