whose work will be presented next month

Glycosides synthesiz~:l:
R = glucosyl, galaclosyl
compounds related to LCME that are more
water soluble and that show higher levels
of activity related to brown lung disease.
Such compounds are glycoside deriva-
tives of LCM~, or ~-˘M~ compounds with
glucose or galactose grouI~s attached. The
researchers have synthesized a variety of
ti~ese derivatives, and some show up to
five times more byssinosis-like activity in
• animals than does ~CME. Moreover, be-
cO~e glucose andI galact~se are ~a~or
~o;~stffuents of c~t~on-pl'ant carbohy-'
drates, it is entirely possible that glycoside
derivatives of LC~E hre components in-
herent to the plant. McCormick and Sli|n-
myozu now are picking through cotton
components to determine whether their
hypothesis is correct.
But even if one of their tCM~.de~ivatives
is discovered in cotton, the search, for thb
elusive brown lung disease ageht will bc
far from complete. Explains McCormick,
"The chances are damn good that there is
,more. than one." []
Another novel tack against Chagas disease
An effective, safe drug for Chagas dis-
ease, a form of sleeping sickness that iri-
feels 10 million South Americans, may at
long last be in the works. Sciehtists at
Albert Einstein College of Medicine
recently re.ported success in using the ex-
perimental anti-tumor drug taxol to in-
hibit in the test-tube the parasite~ that
cause the disease (SN: 8/29181, p. 134). And
now chemicals that help counter sleeping
sickness in rats have been identified and
may eventually be used to treat'Chagas

O, eorge H. Mellow of New York University
School of Medicine i~ New York City report
in the OcL 9 ~cmuc~ The compounds
appear to be rheumatoid factors, which
are pro.duced in the blood of rheumatoid
artbrhis patients;
First, Clarkson and Mellow showed that
lactating rats have an unusual resistance
to..To'Pono~oma le.,isi, the parasite that
causes sleeping sickness in rats; that
blood from lact.ttiog rats tends to clump
~ h.u.i~i, and that nur,~ng enhances rat
pups' survival from sleeping sickness.
These findings suggested that bI0od from
lactating rats contains some cbemi.cal .or
chemicals that help counter sleei~ing
~ickness.
The re~earch(~rs knew that rats infected
with T. lewisi help fight off infection with a
class o[ antibodies called IgG antibodies.
Rheumatoid ~rthritis patients manufac-
ture IgM antibodies that react speciflcafiy
with IgG antibodies and are called
~rheumatoid fdctors." So they hypothe-
sized that the chemicals in blood from
lactating rats that help coimter sleeping
sickness might be th~ rheumatoid fac-
tors--and that by so inter'acting, the lgM
antibodies would enhance IgG antibody
protection against the disease.
To tes! their hypothesis, they first used
standard immunological techniques, to
ideutib, the Z lewisf-ch,mping chemicals
in the lactating rats" blood as IgM an-
tibodies. Then they pat the IgM autibodies

Fina~ test set for Ariane
The fourth and final test flight of the
European. Space Agency's Ariane rocket
has been scheduled for Dec. 14, fi'om the
ESA launch site in Kourou, Guiana. The
first Ariane was launched on the day be.
fore Chirstmas of 1979, and scored a re-
souudlng success. The secoud, on May 23,
1980, ended in a mid-air explosion that
slowed the programby eight mo.nths whim
engineers sought to find and fix the prob-
lem. The third flight took place on June 19
of this year, again a guccess. If the r.emain-
ing test is similarly trouble-free,'Ariane
will graduate to become Europe's princi-
pal gateway to space, and significant com-
petition to the U. S. space shuttle.
From the second flight on, the Arianes
have been carrying satellite payloads to
orbit (those aboard number 2 were de-
stroyed in the blast), and flight 4 is no
exception. Aboard will be MARECS-A, the
firsi of two MARitime Eui'opean Commu-
nications Saiellites, as well as an in-
strumented cai~sule designed to monitor
the new booster's performance. (The cap-
sule wilt also house an .ionospheric
electron-density experiment designed by
a group of young people from France ~
Ariane's principal participant country.)
From there on, Ariane will be consid-
ered an officially opei'ational vehicle, al-
though its first six taunches follow.ing the
test program have been dubbed the "pro-
motional series.= A private organization
called Arianesi~ace has bOen set up to
market the rocket's earth-to-orbit serv-
ices, but the launch business is already
looking good:-Ariane's manifest shows
firm c~mmitments for 13 launches, with
reservations (some of them double-
