Measles Vaccine
Long Way Off,
Scientist Says
Washington - (Science Serv
ice) - There is discouraging
news for America's youngsters
today.
They will continue to be
subjected to the discomforts
of one of childhood's most
common infectious diseases,
measles. This gloomy fore
cast is based on a statement
by a Buffalo virologist that a
measle vaccine is not expect
ed to be developed in the near
future.
Scientists are still a long
way from such a protective
vaccine, Dr. David T. Karzon
of the department of bacteri
ology and immunology at the
University of Buffalo School
of Medicine, told Science
Service.
Distemper Antibodies
Commenting on research
wrth the measles viruses, Dr.
Karzon explained that there
is some relationship between
them and the viruses that
cause distemper in dogs. It
has been established that chil
dren that develop measles de
velop antibodies against both
measles and distemper, he told
an audience at Philadelphia's
University of Pennsylvania.
Scientists believe the viruses
are only distantly related,
however, because this double
action does not occur in all
species of animals.
Puppies immunized with
measles viruses are capable
of challenging very active dis
temper viruses although the
.puppies do not exhibit abun
dant distemper antibodies as
a result of the measles infec
tion. This unexpected reac
tion remains a puzzle, he said.
May Not Be Dangerous
When asked if a distemper
vaccine could produce the re
verse effect, that is, stimulate
the development of antibodies
against measles viruses, . the
virologist replied that he did
not know. For one thing, he
explained, distemper may or
may not be dangerous in man.
As far as is now known, man
does not contract distemper,
but there is no positive proof
that distemper viruses inject
ed into man for the purposes
of producing antibodies would
not affect humans.
Distemper and measles have
similar symptoms which in
clude fever, "runny nose," fa
tigue and discomfort. As a
childhood disease, measles is
relatively harmless if it runs
its normal course. Possible
complications include brain
fever or encephalitis, how
ever. In conclusion, Dr. Kar
zon noted that puppies im
munized with infectious
measles viruses do not de
velop chinical symptoms of
the disease. x
Congratulations
on your
50th
Anniversary
'your official
launched March 17, 1958, led
jto discovery of the pulse-like
behavior of the upper atmos
phere. Scientists attribute the fluc
tuations to changes in the rate
at which the temperamental
sun emits ultraviolet radiation
and charged particles. Varia
tions in such emissions affect
the temperature and density
of the atmosphere at great
heights.
Long -period swelling and
contracting of the atmosphere
was linked to fluctuations in
solar ultraviolet radiation.
Short - term changes were as
sociated with ejection of par
ticles from the sun.
Night-Side Contracts
The observatory also found
a correspondence between the
atmosphere's conduct and the
sun's rotational period of 27
days. Moreover, the report
said, "as the earth rotates the
atmosphere of the night-side,
not directly subjected to solar
radiation, cools and con
tracts." The sun is a fairly stable
star. But it is by no means
quiescent. From time to time
giant eruptions, called flares,
hurl vast numbers of particles
into space.
Some authorities believe
this and other kinds of solar
activity may have a profound
ly disturbing effect upon the
earth's weather.
Not Enough Known
Weather bureau scientists,
however, say that if there is
such an effect, not enough is
yet known about it to help
forecasting.
The Smithsonian Observa
tory did not express an opin
ion on what influence if any
is exerted on the weather by
the sun-induced pulsations in
the high atmosphere.
"All the details of the re
lationship," it said, "are not
yet clear."
Rotation Affects
Growth of Plants
London -(Science Service)
The health of your potted
plants may depend on the di
rection in which you rotate
them.
A New Zealand researcher
took several types of plants
under fixed conditions o f
light, temperature and humid
ity and turned them continu
ously about a vertical axis at
the rate of one revolution a
day.
He found that the plants
used - cyclamen (member of
the primrose family), scarlet
runner beans, and oats were
sensitive to the direction of
rotation. Clockwise rotation,
when viewed from above, in
hibited growth while counter
clockwise rotation stimulated
it.
These findings are reported
in the British scientific jour
nal Nature by Dr. R. L. Jones
of the department of scientific
and industrial research, Do
minion Physical Laboratory,
Lower Hutt, New Zealand, in
hopes that they may be use
ful background to a study of
the twining of plants.
