1. Shifts in Energy Levels Linked to Radio-Protective Capacity of
Substances
"Energy Levels of Metastable States of Biological Objects and
the Mechanism in the Action of Certain Radio-Protective Sub-
stances," by I. I. Sapezhinskiy and N. M. Emanuel', Institute
of Chemical Physics, Academy of Sciences USSR; Moscow, Doklad
Akademii Nauk SSSR, Vol 132, No 6, 21 Jun 60, pp 1441-17X3
In previous research by the-authors (DAN, Vol 131, No 5, 60, 1168),
it was shown that the action of gamma irradiation on proteins, DNA, and
RNA leads to the rise of metastable (biradical) states which are analogous
to those observed due to photostimulation of these important chemical
cell components.
In this research, the authors studied the energy levels of metas-
table states to find the pathways of energy migration and the most vul-
nerable sites in various complex biological structures, and also, the
fact that such research may point to possible lines for research on
radio-protective substances.
Results of various tests are discussed and are presented in a
table. They show the close coincidence of the wave lengths (1+93, 495)
which correspond to maximum phosphorescence for DNA, radio-protective
agents, and also for the propyl esters of gallic acid. The authors pre-
sume that the transfer of energy from the triplet level of DNA to the
triplet energy levels of the protective substances, as a result of
which injury to DNA is substantially diminished, is the most probable
explanation. In doing this, the molecule of the protective substance
is transferred from the basic singlet level to the triplet level.
Preliminary tests indicate that the addition of propyl gallate and
isopropyl gallate to a protein solution substantially diminishes the life
span, (t), of the metastable states; and the extinction time of protein
photophosphorescence, in which (t) is diminished by a factor of 1.5-2.0,
is clearly evident.

2. Joint Presence of Cytochromes and of Succinic Dehydroaenese Revealed
in Cytoplasmic Membranes
"The Cytochrome System in the Cytoplasmatic Membranes of
Micrococcus Lysodeikticus,".by N. S. Gellman, M. A. Lukoyanova
and A. I. Oparin, Institute of Biochemistry imeni A. N. Bach,
Academy of Sciences USSR; Moscow, Biokhimiya, Vol 25, No 3,
May/Jun 60, pp 482-486
The purpose of the research described was to trace the components of
succinic oxidase in the cytoplasmatic membranes and to explain their
connection with succinic dehydrase, the primary dehydrase of succinic
acid.
C PYRG H-fhe authors present the following conclusions:
"Cytochromes of the b, c, and a groups were detected in the cytoplas..
matic membranes of the cells of bacteria Micrococcus lysodeikticus. The
joint presence of cytochromes and of succinic dehydrase indicates the
localization of the succinic oxidase system in the membranes. The sup-
pression of succinic oxidase activity during cell lysis is probably linked
with a disruption in the organization of the enzyme complexes and with
the disruption of the terminal link -- the cytochrome oxidase."

3. Studies of the Diffusion Factor Affecting B. pestis
"The Problem of the Relationship of the Plague Microorganism
to Hyaluronic Acid and the Presence of a Diffusion Factor,"
by I. V. Domaradskiy, G. A. Yaromuk and Z. I. Vasii?yeva,
Irkutsk Scientific Research Antiplague Institute; Moscow,
Zhurnal Mikrobiolo ii E idemiolo ii i Immunobiolo ii, Vol 31,
No 7, Jul 60, pp 113-117
The significance of the diffusion factor (reported by Korobkova) in
the immulopathogenesis of plague is discussed. In considering various
pathogenetic factors affecting B. pestis, the authors included a study
of hyaluronidase, which is reported in this article. They found that
theoretical results disagreed with those of Korobkova.
The presence of hyaluronidase was determined in 20 strains of B.
pestis, one atypical strain of Streptococcus, and strains of Staphy-
lococcus aureus and Cl. perfringens. The B. pestis strains were
avirulent strains EV 1, 17 50.74; and avirulent strains TsD, 94.-96,
119, 125, 143, 435, i83, 485-188, 1435, and 1525. The McLean method
of hyaluronidase determination was employed, with modifications pro-
posed by Mogilevskiy, Kogan and the authors, which eliminated a
number of drawbacks inherent in the Smirnov method.

CPYRGHT
The following conclusion is offered.-
"Experiments with standard and I'rerlhly isolated B. pestis strains,,
caawried out on a parallel, basis with three species of microorganisms
known to form hya1uronidase afforded a basis for stating that B. pestis
does not contsin the enzyme hyaluronideze, which causes depolymerization
of hyaluron.i.z! acid in vitro end fa,cstl.itat,es otai.n diffusion in vivo."

"This review of the authors' research presents data collected for
20 years (1937-1959) on types and variants of foot-and-mouth disease
virus isolated in Kazakhstan and neighboring areas. It was established
that types 0 and C foot and.-mouth virus c .i,.sts for a crmparatively brief
period under natural epizootic conditions, changing into variants of type
0 or OA. It was determnined by observation of foot-and mouth disease
epizootic, that the repeated entry of the virus into the immune animal
organism creates specific conditions for metabolism which makes possible
the formation of new antigenic properties of the virus. In experiments
on guinea pigs and cattle, the modification of type characteristics of
the foot-and-mouth virus is achieved by repeated introduction of the same
strain into an immune animal. Modification of the foot-and-mouth virus
occurred in experiments on guinea pigs with standard type strains: with
type 0, after 16-35 infections; with type A., after 9-49 infections; with
type C. after 5-9 infections; with vH,riart O, af"ter. 15-27 infections; on
cattle: with type 0, after 10-11 infections; with a variant of type 0,
after 3 infections; with a variant of type A2, after 3-4 infections;
with type C, after 4 infbctions. Vaxdations of Ta vines depended on the species of
the animal and the immuno)ogical condition of the organism. Modification occurred
mote rapidly in c xtEle than in guinea pigs; in one immune organism, several
strains of virus with different antigenic properties., which were pre-
served without. change for a long time., wer- obtained by repeated infec-
tion with the same type of virus."

"The possibility of culti..ring Vibrio cholerae in an aerated liquid
culture medium is indicated. The greatest number of microorganisms are
reproduced in seedings of Vibrio cholerae in bouillon, the polyfabricate
of which contains 300-500 mg% amino nitrogen. Cultures of different ages,
cultured under different conditions, can be used as seeding material. The
culturing of Vibrio cholerae in a reactor can be continued for not more
than 12 hours; after 12 hours the intensity of cell proliferation diminishes.
It is demonstrated that the more microbial cells the initial culture contains,
the higher its immunogenicity. In 56.6% of the microbial suspensions, the
content of microbial bodies decreased from 10 to 70% after treatment with
formalin with respect to the initial number of microorganisms. An increase
in the amount of formalin up to 1% during sterilization of microbial suspen-
sionsof Vibrio cholerae minimizes the decrease in the standard of microbial
suspensions prepared from certain strains of Vibrio cholerae and does not
affect the immunogenicity of the vaccine."

"This article is a critical review of the role of proteins and nucleic

tion of the fact that bacteri.ophages and pure viral RNA and DNA completely
devoid of protein can stimulate the infection process does not yet have a
definitive experimental basis. It has been proposed that the internal pro-

In the present work it is assumed that the origin of coordinates for
the system (1) is a unique singular point on the entire plar.ie and that
the right sides, of the equations in question are defined, continuous on
the entire plane, and satisfy the L.psch~.tz eor:?dition in every bounded
fart of that plane. Existence of the limit cycle is proved with the help
of the known theorem of Bendictson.. The limit cycle always exists in a
to ;-shaped.region not containing the singular, point, through the
bound- o1 which the integral. curves ocdy pass or only emerge. In this
ca5ou the inner boundary of the ring may coincide with the singular point.

terms of eigenfunctions remained. open.
Mutually conjugate boundary value problems for an integrodifferential
operator having a retarded argument are presented in section 1 and
asymptote for the eigenfunctions and e3.genvalues is studied.
In section 2 a Green function is constructed for the considered
integrodifferential operator.

A class of systematic codes is considered with detection and correc-
tion of errors which are obtained during utilization of one of the algori-
thms of code construction proposed by V. I. Siforov in his work e.ppearing
in Radiotekhnika i Elektrorika Vol 1, No 2, p 131, 1956. The power of
the codes of the considered class is within those limits which are known
at the present time for the maximum power, of codes. Certain properties
of these codes are investigated and methods to reduce overshooting during
their practical construction are indicated.
