TM-. The autrions an~_'.Yze t-he chemical activity of t-he structure of homo-
geneous alloys in the spots where cracks arise and develop. They discuss the
thermodynamical conditions of intercrystalline failure, the effect of the-grain
boundary state on the surface of the metal and the grain boundaries in homo-
geneous alloys. Intra and in+%ercr-ystalline cracking in poly c--jstall ine metals
is caused by irreversible rrocesses, arising In non-stable structural sections.
On grain boundary sec-ions, grooves (recesses) are formed due to the non-
stability of grain edges forming these boundaries. in pure metal the process is
damped with the forma,~ia_- of an equElibrium angle of the groove; in alloys the
prevaili-ng oxida-fton of one of the componenzs produces local heterogeneity in

TEXT: The stability of alloys against corrosion cracking was found to
change widely in different corroEive media. The stability of the alloy is
assumed to be the lower, the more different the chemical activities of
the alloy components. It is noted that sections with inc-eased chemical
activity develop due to plastic deformation in metal. Sections of increased/.
chemical activity in single crystals and polycrystals were found to be
the origin of cracking. The mechanism of development of sections with in-

ABSTRACT: The existing. methods for gauging the precipitation reaction are
ifar from atrue quantitative determination of the antigen--antibody reactiorlb
'In all the cases one does not know the exact composition of the precipitate
1which is usually contaminated by admixtures which reacted with the reagents
bused. In additionj the usual methods are slow and cumbersome. The present
.paper presents the first results using radioactively labeled trivalent
:chromium-51. The trivalent chromium was chosen because it can be hydrolyzed
,into nonsoluble chromium.hydroxide at pH7 characterizing the usual precipitation
(reaction. The results ".re in agreement with data from other methods.

TEXT% The authors studied the subject mentioned in the title, since the
protective amidine agents cannot be explained by present theories of the
chemical protection from radiation. They determined the degree of the
action of rays upon bacterial suspensions by counting the surviving
bacteria by their ability to form colonies. The experimental objects were
B. anthracis, B. cereus, Cand. albicans, and Staph. aureus-209. The first
three strains were bred by the Gosudarstvennyy kontrollnyy institut

Staphylococcus aureus to Gamma Rays From CoL
-(State Control Institute), the 4th stock by the bacteriological laboratory
of the authors' institute. A cobalt apparatus of the type TYT-400 0
(GUT-400) served as gamma ray source. 1% acetic acid amidine solutions
with pH 5 and subsequent dilution were used for the experiments.
B. anthracis and B. cereus were irradiated with a dose of 300 kr.
B. cereus was found to exhibit an equally high resistance to radiation
as B. anthraciq~ It was found on the other hand that the radiation
sensitivity of both microbe species does not change in the presence of
the amidine compounds used (Table 1). Cystamine has no influence at all
on the resistance of these two bacteria to radiation. At a dose of 50 kr,
cell suspensions of Cand. albicans exhibited a marked resistance to
radiation, although only in a narrow concentration range of the amidines
(Fig., 1), It can be seen therefrom that the greatest effect arises on
dilutions of from 1 1500 to 1: 2500. At 1 :4000 there is no difference
found in the control, In suspensions of Staphylococcus aureus, the amidines

investigated did not act as radiation protectors, but as radiation
sensitizers (Fig. 2). This effect begins at about 1 13000, remains at an
almost constant level up to 1: 30000 and gradually vanishes with higher
dilutions. The authors explain the missing effect of amidines in
B. anthracis and B. cereus by large amounts of wax-like substances in
the cell membranes of these microbes which prevent the amidines from
penetrating~ Amidines are good protective agents in the case'of Cand.
albicans. The effect was weaker, however, as compared with E. coli (Ref.3).
The authors assume that the different effects'exerted by atTA and NPA
on the one hand, and OCFA on the other, are caused by the presence of a
furan ring in ocFA, which raises the radiosensitivity. This assumption,
however, has not been confirmed by experiments. The authors believe
that in the case of c(FA not only the presence of the group

Abstract In catetherization of the heart of patients Nrith mitral

than by the itenosis. r1he increased resistance appear
to be a neuro-fimctional reaction, expressed in spasm

The author describes a procedure, for the diagnosis of coarctation of aorta which
he has used successfully in 8 patients without complications. An intravascular
catheter is passed through a peripheral systemic artery into the aorta and the
presence and localization of the coarctation is determined from the site at which
the catheter gets stuck and from th e pressure curves. Heath - Birmingham

authors have developed experimentally in dozs a new int-thotl for the relief
of congenital heart disease associate(l with inipaire(l pulmonary circulation. In
15 (lo.,,s the superior vena cava was, transected suporior to the site of union of
the azygos vein and the right pulmonary artcr\, was transected ininiediately at
its origin from the main trunk. Tile peripheral stunips of the 2 vessel,; were then
anastoniosed end-to-end. As a result the right hing ww; supplied with blood directly
from the superior vena cava, the blood flow b\-passsing the right heart. E'leven tit)
survived the operation, and in 10 of these the anastornosis remained patent. Cardi~ac
catheterization showed that pulmonary blood flow was -almost equal on both
sides without any significant increase in blood pressure in the area of the superior
vena cava. Angiocardiography demonstrated excellent filling of the right pulmonary
arterial tree. The authors claim that their method is applicable to human cardiac
surgery and has advantages over the Blalock operation and its modifications in the
following respects: (1) The operation places no considerable extra burden on the
heart. (2) It does not increase blood pressure in the main trunk of the pulmonary
artery. (3) The anastomosis supplies pure venous blood to the lung. (4) Endarteritis
is not liable to occur. (5) Technically the operation is not difficult, even when
performed in children. Heath -Birmingham (VI, 9, 18)
