"A Summer Epidemic of Dysentery and Measures Taken for Its Control"
Sofia. Voenno Meditsinsko Delo. Vol 21, No 3- jun 66. PP 52-55
Abstract: An epidemic outbreak of Flexner dysentery affe:cting
150 persons occurred in a military detachment after membars of
the detachment did summer farm work In localities In which
cases of dysentery had been recorded among the civilian popula-
tion. Prophylactic and sanitary-antiepedemle measures had
little effect on the course of the outbreak, whieh--continued
for 10 days and consisted of cycles with a durat4 on of 3-4
days, with the maximum number of new cases-occuring In the
middle of each cycle. The length of the incubation period in
Infections with this disoaiie Is 3-4 days. -One may assume that
the outbreak was due to lack of Immunity on the part of members
of the detachment affected and that It decreased in intensity
as soon as Immunity was acquired. The resistance of the person-
nel to Infection may have been lowered because of overstrain
due to training: greater emphasis on activities not requiring

Thp authors treated 54 patients suffering from psoriasis with aminopterine. Tile
close was half a milligram morning and evening in the course of to days. Twenty
!)ahenLi were stibjecte(I to olle treatment course, 29 patients to more courses. The
ititervals between the courses were 7 to 10 davs. The authors came to the following
conclusion: aminopterine administered in quantities which approach tile toxic
amount erased the skin affection in 40-80% of the patients. The curative effect
manifested itself surprisingly quickly In comparison with the heretofore known and
utilized anti-psoriatic means. The recurrences, how ver, occurred rather quickiy
after the treatment was discontinued. It is the authors' opinion that due to the
toxicity, the practical use of aminopterine against psoriasis should be limited and
should be carried out only under clinical conditions with strict observation of all
contraindications and with a most thorough laboratory (especially haematolegical)
control.

ABSTRACT: The fornation cross-section of the compound nucleusa~,(E) has to be
known in order to analyze a number of reactions involving heavy ons. Thomas
(Phys. Rev., 116, 703. 1059) computed this cross-section in dependence upon the
energy for a number of cases, using the approximation of a rectangular hole,
heavily absorbing ions. Bat this approach Is very rough, since the interaction
of the two nuclei is actually described by the potential. which diminishes
exponentially at great distances. While more realistib models have 11ince been
prq>osed, there are. now indications that the real value of Cr (E) Is considerably

A report is givea of a case of late syphilis, in which there was at the some time an
enormous gumma he site of a child's head on the back, and an ulcergummatous
lesion on the chest. These gummatous lesions developed in a period of 6 months,
one after the other, and 35 yr. after the onset of the disease. Treatment with peni-
cillin-bismuth rapidly led to cure of the skin lesions.

ABSTRACT: The cross sections for''inel'astic scattering of electrons by nuclei with
ixcitation of colloctive,nuq~ear states are calcOated. The calculations are intend-
64 to apply to heavy nuclei to which the unified model is known to afford an ade-
qpate approximation; therefore the "improved" Born approximation of D.Saxon and L.
.J.Schiff (Nuovo Cimento,6,614,1957) and W.Czyz and X.Gottfried (Ann.Physik 21 47,
1~63), which takes approximate account of the distortion of the wave function by
H thp-Coulomb field, Is employed. The transverse terms in the interaction are neglect?-
