contains perhaps any highly active admixtures. Beside the
Imown ingredients (ref 3) Sodium DFF contained phosphorus
glyceric acid and in some series 6-fructose rhosphates
according to the paper chromatography. The effect of these
admixtures in small quantities on the heart is not'vorth
mentioning. Therefore other highly active admixtures-are.
sought in the preparation in question. Sodium DFF solution
was treated with activated charcoal in the case of
different liff-values, the adsorbed admixtures were elated
under various conditions., the extracts were studied chromato-
graphically and controlled biologically (by action an the
heart). After longer work the attempt, to isolate a
substance which was highly active (in a concentration of
approximatively 1:100000) and homogenous, was successful.
The authors denoted it ZZMostimulator cordis, in short ZSC,
till the exact detection of its structure. After this
substance had been obtained.in chromatographically pure
state its chemical structure could be detected. Then the

effect. The detection of uracil in ZSC was carried out by
means of the investigation of the absorption spectrum of
the ZOC solution in ultraviolet light. This spectrum has
a selective absorption with a mw:imm at 260 n@u(figure 1)
which is characteristic of adenyl- and aridine ccimpounds.
Figure 1 shows that the mentioned maximum. vanishes in
consequence of a treatment with brcmine water (ref 6). This
means that the empound in question is a wacll derivative.
Furthermore the chemical nature of ZSC was proved by means
of hydrolysis up to the liberation of the pyridine base in
a 45 % HC102 for 2 hours. By means of chromatographing a
spot with Rf = 0.461 was found in the system of the solvent
isopropanol-alcohol- 10 n HU (21:3:3)- Uracil was
chromatographed in parallel with the hydrolysate as well as
adenine and guanine, the Uracil having Rf = 0,62. Pentose
was determined with orcine according to ref T- It is bound
here to the pyrimidine base. Finally a rati 'o of 1:2 was
proved between the not acid-proof phosphorus and the total
phosphorus. Thui ZSC can be considered as uridine derivative.

sugar, in particular ketose phosphates. The method of prepara-
tion of Stable preparations of the sodium salt of fructos; di-
phosphate (sodium DFhF) (Ref 26) worked out by the author is
worth mentioning. The outstanding role of sugar phosphates in
many biological processes is due to at least two reasons: to
the energetic (Ref 27) and to the structural-chemical (Ref 28)
one. The reactions of the transition of a part of the phosphate

Research of Carbohydrates
dioxyacetone which were developed during the past years are of
outstanding importance for the understanding of the role played
by the phosphates in the course of biochemical processes. The
first reaction takes place by means of transketolase (Ref 29),
the second with the aid of transaldolase (Ref 30). In this con-
nection it is important to point out the recently discovered
breaking of the hydrocarbon chain of sugar phosphates which
proceeds under the splitting off of acetyl phosphate (Ref 34).
In addition to the already known reactions the discovery of
this new reaction of "phosphodesoolysis" provides a more con-
prehensive understanding of the carbohydrate transformations
under biological conditions. On the basi-s of papers (Refs 36-
-38) it was found that beside glycolysis there is a new pro-
cess of carbohydrate decomposition which Engeligardt called
the apatomic or oxidative process (Refs 39-42) (Fig 3). Apart
from the glycolytic and apatomic, process of the decomposition
of glycose, in 1952 a third type of the decomposition process
was discovered to take place in microorganisms, some-times named
after the discoverers _%tner and Doudoroff (Ref 44). Se-,reral
Card 3/6 papers (Refs 45-47) dealt with the clarification of the inter-

mediate stages of this process. The new type of decomposition
is supposed to be of great importance and to occur not only in
microor anisms. Saccharin phosphates play an important role
(Ref M (Fig 4) in photosynthesis besidestheir part in syn-
thetic processes (Ref 50). Another extremely important field of
chemistry and biochemistry of the carbohydrates are the glyco-
sides, above all the 0- and N-glycosides. Recently, a large
amount of natural 0-glycosides was separated and their struc-
ture could be determined. in this connection very peculiar mono-
saccharides were discovered exhibiting a peculiar structure as
well as other peculiarities, among them ramified chains. After
1950 special attention was paid to new groups of N-glycosides
of phosphorylated sugars which are free nucleotides (Refs 58-60).
The presence of "makroergicheskiy" phosphate bonds in nucleo-
side polyphosphates causes their high activity in biological
processes and in particular their taking part in a number of
reactions of phosphorylation. Apart from these general traits
coenzymes apparently exercise a number of specific functions
(Refs 72-79). Recently the author succeeded in separating an

from a yeast fermentation mixture and the preparation of the
sodium salt of fructose diphosphate (Refs 60-81). Nucleotide
polyphosphates may not only serve as initial products for the
biosynthesis of nucleic acids, they also guarantee the process
of the elementary reactions of metabolism. There is good reason
for the assumption that the production and use of nucleotide
polyphosphates will be of outstanding importance in future che-
motherapy. Takin& into acQo1.;:at the difficulties arising in the
chemistry of polysaccharides, the success achieved in this
field during the past twenty years is simply aamazine. Only re-
0
cently it was possible to clarify the structural type of many
highest homopoi-ysaccharides as w.-11 as the decomposition pro-
cesses and the biosynthesis of most JmpGrtant poiysaccharides.
A detailed investigation of all. these pro@lems is not possible
in this paper (Refs B7-89). The invc:stirrations of amyloses
(Refs 90-91), glycogen (Refs 92-107), dextran (Ref 108), the
achievements in the field of the chemistry of cellulose (Refs
109-112) are mentioned as well as a paper on chitin (Ref 113)-

decomposition and the biosynthesis of homopolysaccha-rides are
dealt with (Refs 114-130). During the past years great succes-
ses were achieved in the field of the chemistry of heteropoly-
saccharides. In this connection special emphasis is to be laid
upon the mucopolysaccharides (Refs 133-137). Some of their most
important representatives are described: chondroitin sulfuric
acid (ChS acids) (Refs 138-140). Recently it was confirmed that
several ChS-acids exist. They are either contained in different
sources, or in the same sources but in different quantity. Thus,
ChS-acids - A, B and C - were separated (Table) (Refs 152-155)-
Recent investigations deal thorou'-@Ily with the research of muco-
proteides (Refs 156-159). Among the achievements of the last
five years are the findings in the field of the biosynthesis of
mueopolysaccharides. It is, however, not possible to explain de-
tails so that in this connection only several data concerning
the biosynthesis of hyaloronic acid (Ref 141) are given (Fig 5)-
However, not all problems of the biosynthesis of mucopolysaccha-
rides have been solved. It is, therefore, to be assumed that
these problems will be solved within the near future. There are
5 figures, 1 table, and 167 references, 48 of which are Soviet.

ABSTRACT: The authors succeeded in isolating a substance from a yeast
fermentation mixture and a fructose diphosphate preparation
which is capable of restoring the function of the tired cardiac
muscle in very small concentrations. As long as its structure
was not clarified the substance was called zymo stimulator cordi s
(ZSC). Its structural components are: uracil, pentose and
phosphoric acid. Half of the latter acid is unstable. Thus,
ZSC is to be considered a uridin derivative, possibly near or
identical with UDPh (uridin diphosphate). The present paper
deals with the comparative study of the effect of ZSC and
uridin polyphosphates upon the heart. At an earlier time the
opinion was expressed that UTPh (uridin triphosphate) does not
exert any direct effect, but favors the re-synthesis of adenosin

"Nudikill. ATPh then acts upon the biological object. Comparative
experiments with ZSC, UTPh, UDPh and ATPh on a "whole" i-solated
heart served the purpose of "biologic identification" and
detection of any possible specificity of the influence exerted
by nucleotide polyphosphates. The experiment was made with an
isolated heart of the grass frog Ran& temporaria, which
previously@was exhausted by a Rin,,,,*erfs solution at .7-50 for as
long as 24-48 hours. As had been hitherto the case (Refs 1, 2)
ZSC at a concentration of 10-5 led to a strong increase of the
-6
cardiac contraction amplitude (Fig 1 A). The same also holds at 1
(Fig 1 B). The amplitude does not in-crease abruptly but
gradually after the ZSC introduction. UDPh (Figs 1 V and G)
acts at exactly the same concentrations and in a simi-lar wa-y.
Also UTPh acts in a similar way 2 V). The characteristic
and well-known 3-phase effect 3 A) appeared in experiments
with ATPh (10-5 _ 10- 6 ). Above results have only a provisionall
value. At any rate, they give evidence of a great similarity of
the ZSC effect to that of uri-din polyphosphates, especially of
Card 2/3 UDPh. At the same time the Pl-r-hors determined a fundamen-tally

diverging type of effect of uridin polyphosphates and ATPh,
namely, the first three have a I-phase effect, whereas ATPh at
equal concentration shows a 3-phase effect. Such a sharply
marked specific effect scarcely allows the effect of uridin
coenzymes to be explained by its transformation into adenine
coenzymes. There are 3 figures and 14 references, 5 of which
are Soviet.

ABSTRACT- The authors reported in previous papers (Refs 1,2) that they
isolated a highly active stimulator of heart activity ZSC
(Zymostimulator cordis) from a yeast-fermentation mixture and
the fructose-diphosphate preparation (FDPh). By its nature, it
is related, or even identical, to the uridine-diphosphate. It
was interesting - besides the further investigation of the ZSC -
to look for other possible admixtures which are also present in
very small quantities but exert a strong biological effect. Re-
cently it has been possible to isolate, from the FDPh-prepara-
tion, another substance stimulating the heart activity in a
concentration of 1 : 100000; it is a guanine derivativet apparent-

follows: The m e t h o d of i s o 1 a t i o n consists
in the adsorption of the admixtures present in the FDPh in coal,
etc (Ref 1). After a threefold chromatography, the chromato-
graphically homogeneous guanine derivative was used for in-
vesti-atina the chemical nature and t@e biological effect.
D e t e c t i o n of g u a n i n e. The presence of the guanine
derivative was proved by a blue flaorescence in the ultra-
violet li-ht after the treatment of the chromatogram with
HCl vapors. The absorption curve showed minima and maxima which
are characteristic of -uanine compounds (Refs 3-5). Figure 1
shows that also the optical density at different wave-lengths
speaks for the presence of a guanine derivative. The d e t e r
m i n a t i o n of p e n t o s e was carried out with orcin
according to Massart (Ref 7) before and after bromination. It
has been ascertained that a pentose bound to a purine basis
is present. D e t e r m i n a t i o n of p h o a p h o r u s.
The ratio between the acid-labile and the total phosphorus was
1 : 2.6. The above results lead to the conclusion that the
compound, with respect to its effect on the heart, is a sub-

phoric acid. There are polyphosphate (pyrophosphate )residues
present. From the above paper, it can be concluded that the
active guanidine derivative apparently is a compound of the type
of nucleoside polyphosphates, perhaps a gaanosine-diphosphate.
The e f f e c t of the g u a n i d i n e d e r i v a t i v e
on the f r o g - h e a r t i s o 1 a t e d according to
S t r a u b was tested as in reference 1. Solutions of the gua-
nidine derivative in question were stimulating in a dilution of
1*':100000 (Fig 2). It can be imaged that substances of this type
will constitute representatives of a new group of heart stimula-
tors. There are 2 figures, and 7 references, 3 of which are Soviet.

'ABSTRACT: The purpose of the work was to prepare and characterize the following
alkylglycosylaidnes: methyl-D-glucosylamine (I), methyl-D-galactosylamine (II), methyl
D-arabinosylamine (M), ethyl-D-glucosylamine (IV), ethyl-D-galactosylamine (V),
ethyl-D-oWlosylamine (VI), batyl-D-glucosylamine, (VII), butyl-D-galactosylamine (VIII)
and butyl-D-xylosylamine (IX). The method of synthesis was that of W. Sorokin (Ber.9
20,'783, 1887) and in the case of othylglycosylanines, that of G. E. Votocek and F.
Valentin (Coll. Czechoslov. Chem. Comaun., 69 77p 1934). The yields, melting points
and specific rotations of the compounds obtained are shown in Table 1. IR spectra
showed that the compounds do not contain C=N bonds, I. e., are not Schiff baser.. The
change-in optical activity during bydro3qsis indicates that the compounds are 0-glyco-
pyranosides, with the exception of N-nethyl-D-arabinosylanine, vhIch Is probably an

TITLE: New long-life vane pumps
PERIODICAL: Stanki i instrument, no. 6, 1961, 6-lo

TEXT: New vane putps for the hydraulic drives of machine tools have been
developed by ENIMt in cooperation with the Yel6tskiy zavod'stanochnoy gidro-
apparatury (Yelets Machine Tool Hydraulic Equipment'Plant). The new "r-11 (G)
series pumps will replace the old "A 11 M pumps, i.e. J14 (LlF),-fl 3cp
(L3F), and J7 5 K (1,510, that have h' h hydraulic losses. The article gives
detailed design description of the 1@12-2 (G12-2) and f-12-4 (G12-4) and
dimension charts of other pumps of the series. The maj6r-share of leakage
in the old design is through the passage q3 (Fig. 2), i.e. from the groove
under vanes into the intake space through the butt-end gap between the rotor
and the discs. This explains why wear on the-butt faces of the distributing
discs raises oil loss so much. In the new desi (Fig. 3) the distribution
discs (8) and (7) are made of case-hardened 2 0 r(20Kh) steel with Rc 56-52
hardness, and the disc (8) is floating, i.e. it is pressed to the stator (3)

New long-life vane pumps D040/Dll2
by springs (9) at the start of operation, and by oil pressure during opera-
tion. In Fig. 3, 1 is the pump casing, 2 the cover and 5 the rotor. This
makes the assembling simpler and eliminates the dang6r of jamming. The output
and intake ducts are open, the rotor has no -trunnion. The G12-4 has eight
vanes (4) and the G12-2 twelve. The rubber sealings (10) and (6) are standard.
The stator profile and dimensions were chosen in accordance with recommenda-
tions by I.Z. Zaychenko (Ref. 2: "Stanki i instrument", no. 8, 1956). When
coupled, the G12-2 and G12-4 Pumps (Fig. 4) have one intake and two separate
outlets. Calculation of the pressure on the floating disc is given. The
G12-2 pumps of 5-50 liter/min capacity can work at up to 1440 shaft rpm. The
life-time of the new pumps is 4-5 times longer than that of.the old they are
replacing. Pressure on the floating distributing disc (pressing it to the
stator) must have a certain value (c:4-) that is obtained when the floating
disc surface area under the effect of intake oil pressure (Fin) exceeds F.
1.19 times, i.e. the following condition must be satisfied;
