Isolation and characterization of 19 polymorphic microsatellite DNA markers in the Japanese brown frog (Rana japonica).

We report the isolation and characterization of 19 polymorphic microsatellite DNA markers in the Japanese brown frog (Rana japonica). These markers were tested in 24 individuals each collected from three distinct populations in Ichikai-machi, Tochigi Prefecture. The number of observed alleles per locus ranged from 3 to 24 across all populations, and the values of observed and expected heterozygosities ranged from 0.

Therapeutic and imaging capacity of tumor-localizing radiosensitive Mn-porphyrin KADT-F10 for SCCVII tumors in C3H /He mice.

A tumor localizing radiation sensitizer, KADT-F10, in which two molecules of nitroimidazole fluorinate, KU2280, are bound to side chain residues of a tumor localizing Mn-porphyrin was synthesized and evaluated. Suppression of tumor growth was significantly higher in a group of mice in which a total 50mg/kg KADT-F10 was administered before radiotherapy at 50 Gly (A: n=7) than in a group of mice in which radiotherapy alone was done (B: n=7). In group B, all mice died within 73 days after radiotherapy, while in group A, the tumor disappeared in five of seven mice, and three of seven mice completely recovered 120 days after radiotherapy.
