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...

Status and Perspective of the Red-crowned Crane Based on Genetic Diversity
Although the population inhabiting Hokkaido (island population) of the red-crowned crane had been reduced to near extinction at the end of the nineteenth century, the population size has recovered and continue...

Chromosomal Analysis of Spontaneous Hepatomas, a Derived Cell Line, and Chemically Induced Hepatomas in LEC Rats
Recent banding studies of chromosomes in a variety of human and animal tumors have provided a growing body of evidence that certain specific or nonrandom chromosomal changes are causally related to or closely ...

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...

High Susceptibility to Spontaneous Development of Hepatocellular Carcinoma in LEC Rats
Spontaneous hepatitis was first found in the LEC strain rat, which had been maintained conventionally at the Center for Experimental Plants and Animals, Hokkaido University [1]. The hepatitis appears suddenly ...

Chapter
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...

Origin of the LEC Strain with a New Mutation Causing Hereditary Hepatitis
Over the last 10 years, a large number of animal models for human diseases has been discovered in laboratory mice and rats. Such model animals have become an indispensable tool in many fields of biological and...
