TITLE% The Effect of y-Rays of Cc on Early Stages of Embryogeny in
Rabbits (Vliyaniye gamma-luchey Cc 60 na ranniye stadii

ABSTRACT: Among the poorly examined aspects of the biological effect of
ionizing radiation, the effect on the embryogenj of mammals has
to be mentioned. Even the latest work dealing with this problem
(Refs 10-13) leaves a lot unsaid. In the present article results
are given concerning the subject mentioned in the title. One
hour before pairing, a female rabbit was treated with rays. The
single dose amounted to 850, 300 and 100 r. The dose intensity
was 150 r/min. The femaleanimal was then impregnated with
sperms of the male animal, not treated with rays. The develop-
ing zygote was examined 20, 24, 48, 72, and 96 hours after the
female had been paired with a male animal which had undergone a
Card 1/3 vasectomy. After opening the abdominal cavity, the zygote was

washed out of the oviduct and of the uterus with a 0.9% NaCl
solution. The living macrogametes and zygotes were picked out
of the liquid and examined in a hanging drop under the micro-
scope. In table I it can be seen that 40 female animals were
treated with rays and ovulation occurred in 32 of them. The
rest showed no opening of the follicle. All of the 20 female
animals used for the purpose of control showed ovulation, there
was no exception. 70% of the macrogametes of animals treated
with rays were fertilized (control 97%). Due to the results
achieved, the authors arrive at the conclusion that ray treat-
ment of female animals just before ovulation, does not only
reduce the capability of impregnation, but also disturbes the
further development of the fertilized macrogamete. This is ex-
pressed in the inhibition of the division of the macrogamete
and of the development into further stages. Furthermore the
macrogamete of the female animal under ray treatment stays
24 hours longer in the oviduct than that of the control animals.
The doses of 100 and 300 r also disturbe the normal develop-
ment of the zygote (Table 1). On account of all this one may

TITLE: Increase of the Resistance of Animals to the Effect of Ionizing
Radiationoas a Result of Previous X-Ray Treatment
PERIODICAL: Doklady Akadenii nauk SSSR, 196o, Vol 130, Nr 6, pp 1359 - 1361
(USSR)
ABSTRACT: The authors wanted 1) to investigate the type of the change in
radiation sensitivity of animals as a result of previous irradia-
tionj 2) to determine the dependence of the protective effect
on the experimental conditions. For this purpose 2.5-month-old
(mainly male) white mice were used. The authors studied a) the
dependence of the
rotective effect on the dose of the first
irradiation, and b the same from the period between the first
5
and the second irradiation. The first radiation was made with
6 doses: 15, 25, 50, 100, 150, 200, 250, and 400 r. The dose
of the second irradiation was 600 r. The following served as
characteristic values of the radiation damage: I. survival of
the mice on the 30th day after the second irradiationj N.

body-weightl IV. changes of the characteristic values of the
peripheral blood. The following results were obtained: I. A
protective effect is achieved by previous irradiatlon with doses
of 50-250 r a fortnight before the second irradiation (Table 1).
The maximum protective effect was achieved by a deae of 150 r
of the first irradiation (Fig 1). Using 800 r in the second
irradiation no protective effect could be achieved. A previous
irradiation for 4 times with 50 r at intervals of I week pro-
duced no protective effect. II. In all cases of an effective
protective effect of the first irradiation, the average lifetime
of the test animals was somewhat longer than that of the control.
III. and IV. No protective effect could be observed. Therefore,
the type of protective effect due to previous irradiation dif-
fers from the effect produced by chemical protective agents
(carbon monoxide, sulfurous compounds, narcotics). In the latter
case also a rapid restoration of the body-weight and of the
system of blood formation takes place. Among the hypotheses con-
cerning the nature of the protective effect of previous irradia-
Card 2/3 tion the authors regard two of them as being the most probable:

of Ionizing Radiation an a Result of Previous BO11/B01"j
X-Ray Treatment
1) The protective effect is perhaps connected with the increase
of the regeneration processes in the previously irradiated or-
ganism. 2) It may also be assumed that the protective effect is
caused by the production of antibodies against the products of
protein decomposition by the organism. At present, sufficient
proofs for this or that hypothesis are lacking. However, they
do not exclude each other. They may be only two sides of an
adaptation reaction of the organism to ionizing radiation. The
increase in the radiation resistance has also been found in
plants and bacteria. At present, it is still difficult to find
out whether this phenomenon is based on a common rule. There are
I figure, 1 table, and 22 reference% 6 of which are Soviet.

Comparison of single and fractional action of fast
neutrons on the testes of mice
PERIODICALi Doklady Akademii nauk SSSR, v. 1379 no, 2. 19619 438 - 440
TEXT& The authors compare the biological action of single and fractional
treatment with fast neutrons on the testes of mice. Data published on
this problem differ considerably, Above all, the authors studied the to-
tal damage caused by fractional treatment. Changes in weight and in the
histological aspects of the testes characterized the degree of damage.
Fast neutrons were produced by a 100-kw nuclear reactor, The application
of a radiation dose of 100 rad wass a) single and total, b) divided in-
to four parts with a total of 25 red each per day. The animals were
killed between the 2nd and 70th day after irradiation. Their testes were
fixed with Zenker's liquid as modified by Maksimov [Abstracter's notet
not explained in the text], colored, and microscopically studied. Histolo.-

sis of the tyl,,:,3 of germinal epithelium cells found in different stages of
gametogenesi~ (method by L.C. Fogg, R.F. Cowing, Cancer Res.9 11, 23~ 19519
Ref. 4), The authors supplemented these methods by classifying the system
into three stages. All cells of the germinal epithelium were divided into
five groupes spermatogonia, prespermatocytes, spermatocytee, spermatids,
and sperms. Table 1 shows the effect of dividing the 100-rad dose into
four fractional doses on the change in the weight of the testi.s. Hence the
authors conclude that the latter is considerably reduced by single and
fractional irradiation, i.e., mainly on the 35th day after irradiation.
Fast neutrons are 5-6 times as effective as X-rays. The degree of weight
reduction is constant regardless whether the 100-rad dose os applied to-
tally or in four portions of 25 red each. On the 70th day after irradia-
tion the weight of the testes had not been restored. The intensity of re-
generation was equal in both experimental groups. As to the spleen, the
case was different since its lose in weight wan lower with fractional ra.-
diation doses (Table 1) and X-rays. Germ cells, starting with the youngest
(opermatogonia), gradually disappear under the action of fast neutrons.
At a dose of 100 r, spermatic ducts were found to be not completely empty,

as destroyed mature cells were replaced by younger ones. Also in this
case, the biological effects of single and fractional doses were practi-
cally equal. The authors state that the action of fast neutrons is not re-
duoed by fractional doses. They thank B.M. Isayev, Yu.I. Bregadze and
V.A. Kvasov for valuable advice. There are 2 figures, 1 table and 5 re-

(III), wero subjected to a single whole-body irradiation of 600 r in order
to study the effect of one prophylactic sc injection of 0.2 mg d.iethyl
stilbestrol. propionate (D) administered 10 days before irradiation. The
LD 50/30 for these mice were 538, 490 and 442 r, respectively. Administra-
tion of D reduced the total mortalit b 50 ~ in I and II and by 66.7 %

in III, the first peak (UP to 5 day being significantly reduced and the
second peak (10-12 days) disappearing almost completely. The weights of

thymus, liver, spleen, suprarenal glands and testes were determined,2, 4,
7, 14, 21, 30 and 60 days after irradiwt-ion. Groups II and III differed
originally only in the weight of the tectes, but group I had distinctly
higher liver and spleen weights than the two others. In non-irradiated
mice, D administration did not affect the total bodyieight. The.radia:-
tion-induced weight variations of the thymus were similar in the 3 groups
and not affected by D. The highest weight of liver with the least fluc-
tuatione was found in the moot radioresistant strain 1. The effect of D
on this organ became-evident 2 weeks after the irradiation. The weight
curves of the spleen whose radiosensitivity is reflected in the second
peak of the mortality curve (failure of the hematopoietic system) showed
the highest absolute values and an earlier period of overcompensation in
group I. D accelerated regeneration, inhibited overcompensation and
equalized the otherwise differing spleen reactions of the 3 strains. The---
weight increases of the suprarenal glands produced by separate and com-
bined irradiation.and D administration were similar in the 3 groups. The
difference in natural radiosensitivity was not reflected in the weight
curves of the testes chose regeneration was not improved by D. The diver-
gent radioresistance of the 3 strains is attributed to the different
radioresistance of their spleen and liver, which is evident from the

TITLEt Effect of x-ray irradiation of pregnant animals on variations

PERIODICAL: Akademiya nauk SSSR. Doklady, v. 143, no. 3, 1362, 717-720
TEXT; The postnatal effect of a single intrauterine x-ray irradiation of
200 r at different embryonal periods was studied in mice by complete
blood counts. (1) Hemoglobin quantity in newborn mice was most reduced
after irradiation on the 17th day of intrauterine life (i. U. 1.) '. P.-
(H - 8.6), but was soon restored to normal values; in 45-day old mice,
irr%diation on the 13th day of i. u. 1. produced a significant reduction
R - 7-0) in spite of almost normal values at their birth.
2~ Erythrocyte numbers varied consistently with the hemoglobin quantity.
~3 Reticulocyte numbers were temporarily reduced in newborn animals
ir the 13th - 19th day of i. u. 1. (R - 3.7 - 5-3).
(4) The white blood count of newborn animals revealed no aignificant

variations. Myelopoiesis was not inhibited. In 45-day old mice leucocyte
numbers, neutrophils as well as lymphocytes, were significantly reduced
after irradiation on the 12th day of i. u. 1. (R - 3-1); whereas
irradiation 1 day later affected only the number of neutrophils and
reduction approximated significance (R - 2.5). Thus, the maximum effect
on the red blood of newborn mice was detected after irradiation on the
17th day of i. u. l.; this is probably the most important period for bone
marrow formation. Development of leucopenia and anemia in 45-day old
mice irradiated on the 12th and 13th day of i. u. 1. may be due to
destruction of mesenchyme rudiments of blood-forming tissues. There are
4 tables and 7 Soviet references.

ABSTRACT: Two types or barley seeds, Odessa 17 and Hibernating
Moscows were gamma-irradiated to study the effects of high and low
radiation intensities on seeds in states or forced dormancy and
natural dormancy@ Odessa 17 and Hibernating Moscow were gem=-
irradiated in both states with doses of 12 kr and 15 kr respectively
at different intensities (Odessa 17, 423 r/mIn and 55 r/min; Hiber-
nating Moscow, 301 r/min and 43 rfidn). The frequency of calls with
chromosome aberrations (dicentric bridge and acentric fragments) in
the meristems of the root tips was investigated during mitotic
divisions. For seeds irradiated during the forced dormant state the
effect of the radiation dose rate Is sharply axpressed regardless Of,

germination time. The high radiation dose rates produce much.highor
percentages of chromosome aberrations in the root cells than the low
crates. For seeds brought out of natural dormancy artificially and
.germinating 1-1=ediately, the percentage of root cells with aberrations
is the same for both the high and low radiation dose rates. The same
.seeds brought out of natural dormancy artificially and germinating 10
days later show dirrarencos in radiation intensities identical to the
;seeds irradiated in a state of forced dormancy. The frequency of
,chromosome aberrations in root calls depends on the physical conditiors
of irradiation (type of radiation, dose, rate) and the physiological
state of the -eeds during irradiation. Orig. art. has: 2 tables.

ABSTRACT: Barley seeds in a state of enforced dormancy and organic dormancy (cf.
N. I. Nuzhdin and R. L. Dozortseva, Izv. AN SSSR, Ser. Biolo, no. 5, 679, 1961)
were subjected to the action of gamma-rays or of one of the chemical mutagens
ethyleneimine (EI,, N-nitroso-N-inethylurethane (MIU), and diethanolamine salt of
maleic acid hydrazide (HMA). The results obtained on irradiation with gamma-rays
confirmed the earlier finding by Nuzhdin to the effect that the number of chromosome
aberrations produced differed greatly depending on whether the seeds were in a state
of enforced or organic dormancy. The number of aberrations produced by gamma-
irradiation and EI was greater for seeds artifically brought out of organic dormancy
and germinating 10 days later than for seeds treated in the same manner and allowed
.5

L 38250-M
ACC NRt AP6028672
to germinate without delay. The same difference, but to a lesser degree, was
found for seeds treated with HM, while no effect of the length of time elapsed
before germination was observed in the case of seeds treated with NMU. Upon
the action of gama-rays, bridging and fragmentation of chromosomes occurred
in a ratio of,1:1.0. This ratio was 1:1.6 and 1:1.4 on treatment of the seeds
with EI and HKA, respectively. The results obtained showed that the mutagenic
effect of gamma-rays, EI, and HMA depended to a considerable extent on the
physiological state of the seeds. Orig. art. has: 1 table. IJPRS: 36,9321

ABSTRACT: Investigations performed under laboratory and, in part,
under pilot-plant conditions, with ores from the Tur'insk group
of deposits shows that Cu recovery may be increased by the use
of lime in the comminution cycle (10-30 g/rn3 CaO), while py-
rite and calcite concentrates may he obtained as by-products
by the flotation of Cu tailings, and,low-phosphorus Fe concen-
trate by magnetic separation. Process diagrams and procedures
selected under laboratory conditions are adduced.

ABS~RACT: A description, an error analysis, and the results of an experimental!
investigation are presented of an analog converter (a laboratory model) that turns
q electrical resistance into a proportional period of a-c oscillations. The converter
'includmi an, RG generator, a Wien bridge, and an amplifier. Two frequency-
'dependetit bridge arms, which constitute an L-shaped quadripole, serve as a
positive -feedback circuit to the generator; the remaining two arms, an a

A- linear relatio- n between the input resistance and output period is claimed. The
-_error, at high amplifier gains, is largely due to the variation of capacitances in
,the Wien bridge. The deviation of the output period, when the converter is used
.as a thermometer, is determined by tho temperature coefficient of the resistance
thermometer and by the measurand range. The possibility of attaining an overall I
system&tic error of about 0. 1% at an ambient temperature of -20+ 30C and a
supply --voltage variation of 10% io claimed; Orig. art. has: 4 figure a and
