| Research Abstract |
1. Morphological: Mandible shape analyses were performed on more than 30 inbred strains of rats. almost all strains were clearly discriminated by this method. A more simple method using discrimination chart faulted to be practical use (Goto).
2. Biochemical: Pg-2, Rtp-1, and Rtp-2 were found to be polymorphic among inbred strains, and to linked with Pg-1, Mup-1, and c, respectively. zi gene was assigned to LG II (Yamada). Procedures for typing Ahd-2, And-C, Akp-1, Gst-1, Hao-1, Pgd, and Tam were established (Matsumoto). Genetic analysis on Ld-1 is proceeding. A beige-like mutation was found in DA strain (Nishimura). A procedure to test Hba locus was established, but no polymorphisms were detected. Genetic analysis on a cataract of the CWS strain is proceesing with mousecrystaline and rat chymotrypsin cDNAs (Shoji). Simple methods for detecting C6, Gc, Gdc, Es-Si, Es-1, and Es-2 were devised (Hayakawa).
3. mtDNA cleavage patterm: 7 types of the cleavage patterns were found among laboratory rats, and the types of many inbred strains were determined (Hayashi).
4. Immunological: A strain of WIN with RT1 recombination was established. RFLPs were found using human Dp- probe (Natori). RFLPs were found using mouse class II genes, A , E , and E probes, and 5 types were found among inbred strains, and 6 types among wild rats (Moriwaki).
5. Somatic cell hybridization and in situ hybridization: GSTP, several onco-genes, and other genes were assigned to chromosomes by these methods (Yoshida). Angiotensinogen gene was assigned on chromosome 19q (Yamada).
6. Cytogenetic: Characterization of Ag-NORs were performed on inbred strains. A precise banding method revealed about 450 bands along with the whole chromosomes (Sasaki).
Gereral: Derivations of many inbred strains of rats in Japan were traced. Genetic profiles of the 63 major strains were determined. Manuals of the several typing procedures were set up. A draft "Manuals for genetic monitoring of the rat" was proposed (all Members).
