Mouse L cells are X-irradiated at various doses under aerobic and hypoxic conditions, and the colony-forming ability is examined. The survival curve is exponential under the extremely hypoxic condition, and the oxygen enhancement ratio is calculated as 3.56. The presence of an organic nitroxyl free radical (N-oxyl) increases the slope and the shoulder size of the survival curve, with the enhancement ratio at 1.63. The evidence suggests that N-oxyl acts as oxygen-mimic

In the Chinese Funa (Carassius auratus auratus), the C-banding pattern of chromosomes is investigated. The Chinese Funa is characterized by the second largest chromosomes with remarkable C-bands on their short armes as markers. There are two such markers in the female and one in the male. These findings are consistent with those derived from the Gold-fish varieties.
Further, the Gold-fish and the Chinese Funa (C. a. a.) are the same in their electrophoretic patterns of muscle protein. No such feature is not observed in five subspecies of the Japanese Funa.

Distribution of the Ceylonese type black rats was studied in 90 specimens obtained in 10 localities of Sri Lanka. The black rats of this type are isolated in the central highland, while the Oceanian type black rats distribute in the surrounding coastal area. Hybrid rats between these two types occur in the central lowland and coastal area.

Thalamic Afferents to the Anterior Part of the Lateral Gyrus in the Cat Studied by Retrograde Axonal Transport of Horseradish Peroxidase

With regard to the thalamic afferents, appreciable differences between areas 5 and 7 in the lateral gyrus were noted. Area 7 in the lateral gyrus receives fibers mainly from the posterior lateral and medial pulvinar nuclei, whereas area 5 in the lateral gyrus receives its major input both from the posterior lateral and medial pulvinar nuclei and from the ventral lateral nucleus, as do areas 5 and 7 in the suprasylvian gyrus. In addition, area 5 in the lateral gyrus receives extremely few fibers from the paraf ascicular and centre median nuclei.

(1) The activity of urinary α-galactosyltransferase is nearly equal to that of serum or saliva enzyme. (2) Under NaCl containing buffer condition, purification procedures involving Sepharose CL-4B gel filtration showed the homogeneity of the molecular size in the three α-galactosyltransferases. (3) The pI of the urinary α-galactosyltransferase is similar to that of the saliva α-galactosyltransferase and significantly different to that of the serum α-galactosyltransferase, which is more positively charged.

Soluble HLA leukocytic antigens (HLA A2, A9, A10, B40) were sufficiently stable to be detected by the cytotoxicity inhibition test after the storage for more than six months at 10°C or one year at -70°C. The antigenic stability would be advantageous in application for medico-legal practice.
