Data are presented on the cytological studies of spermatogenesis of apes exposed to x-radiation doses of 150 to 500 r. The studies were concerned mostly with the dividing spermatogenes in order to determine the composition of Macaca mulatta chromosome complex and with dividing spermatocytes of the flrst order for determining the character of chromosome reorganization taking place under the action of ionizing radiation. Tabulated data show that sperm of ape No. 1 irradiated with 150 r and killed two years later underwent 5% of anaphase changes; the sperm of the No. 2 ape irradiated with 450 r and killed two years later showed a disturbance about 6%; in the ape No. 3, irradi ated with 400 r and killed 11 days after, the disturbance is about 28%. Such a great number of anaphase changes indicate considerable chromosome disturbances, which within two years eliminate the most damaging ones and multiply the least damaging to 5 or 6%. Consequentiy, it may be deduced that the part of the chromosome reorganization resulting from irradiation, while multiplying, may retain and induce new different reorganization during the span of the animal's life. Hence, the opinion that after a long interval and repalring processes the organism re- establishes the normal fertility is erroneous. Moreover, the radioinduced disturbances may induce various pathological effects in the mammals and their progeny. (R.V.J.)
