Texas researchers look
for blood subsdtution
b United Press International
Washington — There is
til) no substitute for real human
Blood, but Texas researchers
bave reported progress on a
emporary replacement made
m cattle blood which could be
toon in emergency surgery or
( the battlefield.
Researchers reported they
ed the product in laboratory
abbits and found it carried ox-
[en to tissues almost as well as
II blood, without causing an
imiunological reaction. It re-
| tins to be seen, however, how
te product will perform in
eople.
i “This may be a good substi
tute for blood,” said Dr. Mario
Feola, professor of surgery at
fixas Tech University and an
authorof the study, published in
Surgery, Gynecology and Ob
stetrics.
IlThe idea behind blood substi
tutes is to find a fluid that can
carry oxygen to tissues and re
plenish lost volume in cases
where real blood is unavailable,
whether for supply reasons or
lack of proper type.
ISuch fluids would keep the
patient alive for at least several
hours, until surgery can be per
formed, blood supplies arrive or
transport off a battlefield is
arranged. They are not in
tended to be permanent blood
substitutes, nor would they eli
minate the need for blood dona
tions.
Scientists have been pursuing
two avenues toward such a fluid :
“artificial” blood and hemoglo
bin solutions.
An artificial compound called
Fluosol, manufactured by the
Green Cross company of Japan,
is being investigated at several
centers nationwide. The ox
ygen-carrying substance
achieved good results in early
tests.
Hemoglobin compounds are
made from human hemoglobin,
the part of the red blood cell
which carries oxyegen, or anim
al hemoglobin.
The problem with hemoglo
bin compounds has been purity.
The team from Texas Tech and
West Texas State University
used a special filtration process
to purify hemoglobin from the
blood of Hereford cattle, Feola
said.
Feola said a bovine hemoglo
bin molecule is similar to a hu
man one, so the compound may
not cause any immunological
problems provided it is adminis
tered to a patient only once, in
stead of used as a long-term life-
sustainer.
If given repeatedly, it could
be rejected, he said, causing
hemorrhaging and other prob
lems.
The advantage to cattle blood
is that it is more readily available
than human blood, the surgeon
said.
“We chose bovine because hu
man blood is in short supply,
and it doesn’t seem to make
sense to me to use human blood
to make a substitute for human
blood,” he said.
He estimated about a year of
animal testing remained before
the compound could be tried
out in humans.
The Army has been investi
gating hemoglobin compounds
made from human blood for
some time. Dr. Robert Bohn,
chief of the blood research divi
sion at the Letterman Army In
stitute of Research in San Fran
cisco, said human trials won’t be
considered for three to five
years.
Bolin said the main snag in
research so far has been that the
product stays in a test animal’s
bloodstream only about five
hours before it is cleared out by
the kidneys.
The Letterman team is trying
to modify the product by linking
the small hemoglobin molecules
together, which the Texas team
also did, making them harder
for the kidneys to filter out.

Train crash near Baytown
Human error causes wreck
United Press International
BAYTOWN — Human error
was blamed Monday for a rail
road accident in which the en
gineer of a moving train slam
med into a line of parked rail
cars early Saturday, killing four
men.
“We have determined the
cause to be the failure of the
head end crew (moving car) to
take action to stop the train short
of the cars that were on the
track,” said Southern Pacific
Transportation Co. spokesman
Tony Aleman.
“There was no indication the
brakes were applied,” he said.
Aleman said the moving train
left Baytown about 4 a.m. Satur
day. About 5:15 a.m, witnesses
said they heard the accident.
Aleman said the train was
operating under “yard limit
rules,” which mandates that a
train in the yard must be able to
stop within one-half of the dis
tance of the range of vision. For
example, if the engineer can see
100 feet ahead, he must be able
to stop within 50 feet, Aleman
said.
And, he added, no one is per
mitted to travel at speeds over 20
mph. Officials initially said the
train was moving about 20 mph.
Before dawn Saturday, a loco
motive, caboose and 10 tank cars
slammed into a parked 41-car
train which was waiting to be
moved to another location. Four
Southern Pacific employees, in
cluding the train’s engineer, two
brakemen and firemen, were
killed by the accident. A fifth
employee was taken to Her
mann Hospital in Houston suf
fering from two broken legs and
an injured arm.
James Wilbert Muchow, 59,
the conductor and only surviv
ing witness, still must be inter
viewed, Aleman said.
The Harris County Medical
Examiner’s office reported the
four men died from injuries suf
fered in the accident.
Aleman said by 7:20 p.m.
Sunday, all but one car had been
moved. The remaining dam
aged tank car, however, was not
blocking the tracks, which are lo
cated in a piney forest about
three miles from Interstate 10
near the Cedar Bayou Industrial
area in Baytown.
Officials from the National
Transportation Safety Board,
the Texas Railroad Commis
sion, Department of Public Safe
ty and the railroad company are
all investigating the accident.
Aleman said it is not uncom-
> £
mon for trains to be left on
tracks for later pickups, but the
employees on the moving train
could have contacted headquar
ters to find out when the station
ary train would be moved. No
communication between the
train and officials had been
made, Aleman said.
The force of the impact
knocked the mangled caboose
27 feet off the tracks. One of the
men who died was in the caboose
with Muchow. Two loaded tank
cars derailed, a third car’s front
wheels also derailed and a tank
car carrying a low grade jet fuel
landed on top of the locomotive,
shearing off the back end of the
engine.
