1232411} Histochcmical study of the "adrenocortical lipid

after oral administration was not exclusively segregated in any 1
liver cell fraction, most of it was found in the microsomal frac
tion. I was distributed according to its lipid-sol, property
rather than by virtue of its reaction with protein. In rats fed
I, the liver microsomal enzyme which catalyzed the oxidative
demcthylation of />-chlorn-A'-methylaiiiline-HCl (II) increased in
activity. A no effect dosage for the stimulation of demcthylation
of II by dietary gossypol was 50 mg/kg. The I stimulation of
rat liver microsomal oxidates seems to be due to an increase in
enzyme synthesis since it did not alter the Km (0.7 X lO^W/)
but increased the max. velocity of I demcthylation (33%). The
ability of rat liver microsomal enzymes to dealkylate some car
bamate pesticides was increased by the oral administration of I.

123243s Exploratory study of automobile driving perform
ance under the influence of low levels of carboxyhemoglobin.
Kay, A. M.; Rockwell, T. H, (Dep. Ind. Eng., Ohio State Univ.,
Columbus, Ohio). .4tin. A'.}'. Acad. Sci. 1970, 174(Art. 1),
390-408 (Eng). Estd. automobile conens. of CO result in 8%
of the nonsmokers having blood carboxyhemoglobin concn.
levels greater than 7r', and 4% having greater than 14% car
boxyhemoglobin, assuming that they were exposed for two hr or
more. Smokers would have carboxyhemoglobin levels up to 15%
higher than these depending on their smoking habits. Several of
the effects of carboxyhemoglobin were definitely detrimental to
driving performance.

123244t Effect of carbon monoxide on human performance.

dore, James (Old Dominion Univ., Norfolk, Va.). Ann. N.Y.
Acad. Sci. 1970, 174(Art. 1), 409-20 (Eng). A study was under
taken to dct. the effects of CO on relatively simple applied per
formance tasks. Carboxyhemoglobin (COHb) levels reflected
a direct relation with the ambient CO exposure levels. The in
dividual performance curves revealed no consistent differences as
a function of low levels of CO exposure. Harry \Y. Gordon

1970, 174(Art. 1), 421-4 (Eng). No effect on performance of
the crit. tracking task of Jex (1900) attributable to CO exposure
was found. An empirical relation was obsd. between pulmonary
CO and blood carboxyhemoglobin values. Harry W. Gordon

114(39), 1044-5 (Neth). Statistics were gathered in the Nether
lands on poisoning by chom. compds. other than compds. for
medical use. Poisoning hv CO was the most frequent type dur

rialpruefungsamt. Nordrheim-Westfalcn, Dortmund-Aplerbeek,
Gcr.) yni (Per. pad. Jn<>.) Z. 1971, J 13(1), 20-4 (Ger).
The toxicity and irritating effects of smoke and products of the
thermal degradation of plastics on rats were studied. The
possible drtn. of relative toxicity of these combustion gases is
also discussed. The toxir cfiects of gaseous pyrolysis products
lonitrile, polymcthacrylates, and other synthetic polymers were
studied on animals and humans. At 2-300, these polymers gave
off gases which were less toxic to rats than those of wood or rubber.
PYC combustion gases were the most toxic of the synthetic
plastic decompn. products tested.

123248x Toxicity of bilirubin. Beck, Kurt (Gastroenterol.
Abt., Med. Univcrsitaetsklin., Freiburg/Br., Ger.). Dad. Z.
Verdau. Stoffivechsclkr. 1970, 30(1-2), 47-51 (Gcr). The i.v.
LDm of bilirubin (I) in rats is "*-150 mg/kg. The animals be
come atactic and die in tonic convulsions. Increased serum
transaminase values, necrosis of liver and myocardium, severe
renal tubular damage, and marked hemolysis with hcinoglobi-
nemia and hemoglobinuria were obsd. By inhibiting respiration
and decoupling of oxidative phosphorylation, I blocks its own
detoxication, which depends on normal oxidn. and intact oxida
tive phosphorylation. The toxicity of I is higher in adrenal-
ectomized animals, which is partly due to glycogen depletion in
the liver. This increase of toxicity is partly prevented by pre-
treatincnt with synthetic glucocorticoids. Kurt H, Ziugraf
12324Qy Lead poisoning in cattle: brain lesions and hema
tologic changes. Christian, R. G.; Tryphonas, L. (West.
Coil. Vet. Med., Univ. Saskatchewan, Saskatoon, Sask.).
Amor. J. Vet. Res. 1971, 32(2), 203-10 (Eng). In cattle with
Pb poisoning, diagnosed initially by clin. and toxicol. observa
tions, gross brain lesions consisting of cerebrocortical softening,
yellowish discoloration, and cavitation, were obsd. only fh those
with prolonged clin. illness (>9 days), being most severe in the
occipital lobes, but the tips of most cerebral gyri were affected.
In acute Pb poisoning, microscopic lesions varied from diffuse
capillary activation to scattered focal areas of status spongiosis
and necrosis of the cerebral cortex. In subacute and chronic
poisoning, the microscopic lesions were located at the gyral tips
and ranged from different degrees of status spongiosis, astrocytic
swelling, and nerve cell degeneration to severe cavitation and
vascular proliferation. Exptl, induced Pb poisoning in 3 2-year
old cattle produced acute, subacute, and chronic syndromes with
clin. and pathol. features similar to those obsd. in naturally
occurring Pb poisoning.

123250s Intraerythrocytic 2,3-diphosphoglycerate and carbon
monoxide exposure. Astrup, I'oul (Dep. Clin. Chon., Rigs-
hosp., Copenhagen, Den.). Ann. N.Y. Acad. Sci. 1970, 174
(Art. 1), 252-4 (Eng). 2,3-Diphosphoglycerntc conens. were
measured in the blood after 24 hr exposure of normal individuals
to CO, leading to approx. 20% carboxyhemoglobin. The results
indicated an 8% fall in 2,3-diphosphoglyccrate, resulting in a
higher affinity of Hb for O and a displacement of the oxyhemo
globin disxocn. curve to the left. The same thing occurred when
the percentage of reduced Hb was diminished by exposing pa
tients to O inhalations or high atm. pressure i2 atm).

(Sell. Med., Univ. Pennsylvania, Philadelphia, Pa.!. .Din.
N.Y. Acad. Sci. 1970, 174(Art. 1), 255-0(1 (Eng). Small amts,
of CO directly interfere with alveolar gas exchange. The tissue
hypoxia produced by CO inhalation may be accentuated by
rather marked degrees of arterial hypoxemia in patients with
heart or lung disease. The arterial hypoxem'.. in these instances
results from the CO-induced changes in the si.., >e of the oxyhemo

123252u State of the biliary tract of pile's and technicians

(Russ). A group of 102 pilots and 30 air technicians working
with client, poisons of the chlor- and phnsphoorg. group was
compared with a group of 104 pilots and 11 air technicians not
exposed to the poisons with respect to their biliary functions. A
higher frequency of biliary tract diseases was found in the ex
posed group and often chronic cholccystoanciocholitis had a
latent course. Duodenal probing is recommended to ensure
early diagnosis, and prophylactic hygiene is suggested.

mechanism of ion retention (poisoning) by the isoporous ion ex

exchangers. In all cases, the retention of large ions, which re

crosslinks between the exchanger macromols. which hinder the
