Vostok III and Vostok IV as a biological sensor, The advantages of lysogenic
,bacteria as biological sensors stem not only from their extreme sensitivity~
to various types of radiation, but also from the fact that induced changes~are
directly proportional to the dose of irradiation. In addition,.E. coli was sub-'
jected to 'the combined effects of radiation and vibration in ground experiments.
Vibration was produced by means of a vibrator with frequencies of 3 5, 7 0, and
700 cps, an amplitude ranging from 0. 4 to 0. 005 mm with a load. equal to 10 g,
for periods of 15, 30, and 60 min. C060 in doses of 1,00 r at a rate of 21 r
per min served as a source of radiation. Lysogenic bacteria carried on space-'
ships Vostok III and Vostok IV revealed induction of genetic changes produced
by space-flight factors which was indicated by a significant increase in the
number of. phage particles. The induced effect was more pronounced on
,Vostok III than on Vostok IV. . Forty,-eight hours after its return to earth,J the
bacteria carried by Vostok III had produced 4. 6- times as many phage particles
as controls which had remained on earth. Ground experiments with vibration
indicate that the combined vibration and gamma irradiation, followed by a
second exDosure to vibration,, double the biological effectiveness of, garmna, rays..

ABSTRACT:. Experiments were performed on the Voskhod-l and'Voskhad-2 spaceships to
test the effects of spaceflight on lysogenic cultures of E. coli'K-12 (X). The

cultures were carried in 1.5-m1 ampules on board spaceships ~n-S-Ei_-Leonov's spacesuit

mercaptooropylamine, Controls were kept at the cosmodrome and at the home laboratory.
Results showed that on the basis of viability there was no difference between samples

the protective properties of 0-mereaptopropylamine. An.attempt was made to determine
whether spaceflight sensitized lysogenic.cultures of E. coli.K-12 (X) toconsequent
exposurelto small dosea of x-rays. Results showed thatphage produ'ction,in space-
flown samples was almost identical tothat of the controls. In additions air-dried
seeds of.pine and winter wheat (PPG-186) were carried on Voskhod-21and in Leonov's
pocket during his EVA for the purpose of determining the ge netic. effects of space-
flight-factors. Results did not reveal any substantial differences between the two
space f light-exposed groups of seeds and Lhe controls. It is assumed that the absence
of the effects of spaceflight factors on lysogenic. bacteria and seeds,of,higher.
iplants in these two flights.is due to the.particular conditions.under which these
flights took place. Orig. art., has: 5 tables'.~ [BMI

,effect and the time of exposure in spacewas not established. The results
obtained make it possible to assume that the biological effect in the above
experiments depends on the combined effect of spaceflight factors, and
.specifically vibration, weightlessness, and radiation.
Ground experiment's have indicated that the sensitivity of a lysogenic
bacteria :system to gamma irradiation (C06~ increases if the bacteria were
,previously exposed to vibration. These results not only.confirm this
supposition but make a more differentiated approach to evaluation of
.various spaceflight factors possible. However, in order to obtain a
,more complete picture of the genetic and radiation hazard of such
flights, it is necessary to consider data obtained with more highly
organized biological objects. Consequently, the results of spaceflight
experiments performed with single-layer cultures of somatic human
cells are of definite interest. In the series of experiments carried out
on Vostok-1, -2, and -4,it.was found that viability, and such indices as
the coefficient of proliferation, the percentade of dead cells, and the
morphological, antigenic, and cultural properties of the tissues, did
not differ substantially from controls which were kept at the cosmodrome
or the laboratory.

a cumulative biological effect on human cell cultures. However a
direct dependence of biological effect on length of spaceflight expo-

to note that when the same Hela cells used on Vostok-4 and Vostok-6

TEXT: Until recently the communication rangefor9*-12 (Yak-12)
aircraft leaving Tallin ceased after 30- 40 km. In the fall 6f7T-95-9a
new control method was developed.based on.the entry of:each Yak-12 flight
into the dispatcher graph, showing the altitudel orientation points and
azimuths according to APri -6 (ARP-~6). ~ This communication range was extended
clover the whole of:Estonia,and,proved of great,value.,.ADS zone dispatchers,
..maintain th's contact tationof the neares
I via the ultra-short wave radio s t
airport or heavy airborne aeropla.ne. Receiving broadcasting stations are
also used for this.purpose as they- Icanbe heard.by the Yak-pilot Iat. certain
q
times on his AFX -5 (ARK-5 , receiving.set. The described method is applied
on all inland routes. as well as during flights ona chemical or medical mis-
sion.
