ジャーナル フリーAbnormality in size of the Y chromosome was observed in 6 out of 7 male patients with neuropsychiatric diseases. Mensural examinations revealed that the long Y chromosome in cases 1 to 4 corresponded in length to chromosomes of group 16-18. Case No. 5 had a short Y chromosome which was much shorter than the chromosome 22. Of special interest is that patients with neuropsychiatric defects here studied showed the anomaly in size of the Y, although current reports indicate that the unusual length of the Y seems to be not necessarily associated with phenotypical anomaly in man.抄録全体を表示PDF形式でダウンロード (669K) -

ジャーナル フリーAn investigation was made of the effects of fission neutrons on the induction of visible recessive mutations in early and in late gonial cells of the silkworm. The results were compared with those of our previous reports, in which 14MeV neutrons and 137Cs γ-rays were used.
1) Dose-mutation frequency curve for fission neutrons is essentially the same as that for other radiations, showing a slow rise in the lower dose range but a rapid rise in the higher dose range.
2) Mutation response to fission neutrons was almost similar for male and female gonial cells, although higher frequencies were observed for fission neutrons than for γ-rays or 14MeV neutrons.
3) When radiation doses producing a frequency of 10-3 of visible recessive egg-color mutations were used as a criterion, the relative biological effectiveness of fission neutrons to γ-rays was about 1.7 to 2.4 for early stage gonia and 3.0 to 4.2 for late stage gonia. Similar results have already been reported for 14MeV neutrons, although the values were smaller.
4) All the dose-frequency curves obtained in the recent series of our work with γ-rays, 14MeV neutrons and fission neutrons are given in the present paper to make them available for further investigations in this field.抄録全体を表示PDF形式でダウンロード (1120K) -
V. PROCEDURES FOR TAKING X2-SEEDS IN RELATION TO TILLERS FOLLOWING SEED IRRADIATION IN AUTOGAMOUS PLANTSYOSHIO YOSHIDA1965 年 40 巻 2 号 p. 125-133

ジャーナル フリーTo detect at least one desirable mutant with a minimum total number of X2-plants or of combined X1- and X2-plants, two methods were established as suitable in relation to tillers of X1-plants.
They are: a type of the “one-plant-two-grain method” (method D2) and of the “one-plant-three-grain method” (method E3) in which one grain is taken from each of two or three heads of an X1-plant respectively.
These methods have been evaluated by considering the probability that one or more plants with the mutant allele in homozygous recessive form will appear in the total X2-plants in relation to the number of heads per X1-plant and to the independent degrees of mutation among the heads of the X1-plant.
The “one-plant-one-grain method” (method C) proposed by Yoshida (1962) is the best when the number of heads per X1-plant (t) is equal to or smaller than three and method C or D2 is the best when t_??_4.
No single method is known to cover all of the advantages. However, methods D2 and E3 will be better than the “one-plant-two-grain method” and the “one-plant-three-grain method” proposed in the first report of this series when t_??_2 and t_??_3 respectively. Generally speaking, it does not seem advantageous to use the “one-ear-one-grain method”. especially the “one-ear-two-grain method” and the “one-ear-three-grain method”.抄録全体を表示PDF形式でダウンロード (761K) -
XXIV. CELLULAR DAMAGE INDUCED BY SOLARSON (BAYER) IN HELA AND HL-C LINESYANAGI KIMURA1965 年 40 巻 2 号 p. 135-140

ジャーナル フリーThe damage to tumor cells following the application of Solarson, an arsenical medicine to remove warts, was cytologically studied in HeLa and HL-C cells in tissue culture. The abnormalities induced in cultured cells by the agent are: partial agglutination of chromatin, swelling or deformation of nucleoli, and the production of cytoplasmic inclusions. The pattern of response to Solarson was similar between HeLa and HL-C cells, while the effect was more severe in the former than in the latter at comparatively low concentration.抄録全体を表示PDF形式でダウンロード (1776K) -

ジャーナル フリー1. アサガオの品種間雑種に生ずる腫瘍は遺伝的のものと考えられる. ここで用いた056, 058の両系では林風と獅子の両遺伝子の共存が腫瘍生成に関係していると推察される. また笹遺伝子はそれを強めることに関係しているようである.

ジャーナル フリー台湾省在住の福建系台湾人2,984名, 広東系台湾人1,219名, 台湾原住民族のうち平埔族に属する Siraya 族337名, 高山族に属する Saisiyt 族259名, Bunun 族288名, Rukai 族328名, 総計5,415名についてPTC味覚能力を紙片法によって検査し, 次の結果を得た.
1) 味盲の頻度には男女間に有意差がみとめられない.
2) 味盲の頻度は Saisiyt 族 (10.8%) と Bunun 族 (10.1%) が最も高く, 平埔族 (7.7%), 福建系台湾人 (5.3%), 広東系台湾人 (4.5%), Rukai 族 (1.5%) の順である
3) 福建系と広東系の台湾人の間には有意差がない.
4) Siraya 族には大陸系台湾人よりも味盲がやや多いが, 差は有意でない.
5) 高山族の味盲頻度には部族間に非常に大きな差があり, 地理的遠近やABO血液型分布との間に相関がなく, 地理的•社会的隔離にもとづく遺伝的浮動の結果と考えられる.抄録全体を表示PDF形式でダウンロード (670K)
