nine caused a fourfold increase in weight gain and almost halved the amount of
food required per gram of weight gained. Baking and autoclaving the field peas
decreased the growth-promoting properties of the protein, although the food intake
of the rats did not change. The addition of cystine to the autoclaved peas permitted
a rate of growth comparable to that on the diet containing raw peas. Rats
fed the raw pea protein (10 percent level) plus 0.3 percent methionine as the sole
source of protein made 47 percent more gain and required 25 percent less food per
unit gain than rats fed casein at the 10 percent level. "Apparently the Alaska
field pea is an excellent source of the amino acids essential for growth, with the
single exception of methionine."
Creatine and creatinine metabolism, H. H. BEARD (Brooklyn, N. Y.: Chemical
Pub. Co., 1943, pp. 376-, illus. 6).-This monograph critically reviews the experimental
work on creatine and creatinine metabolism published in recent years,
more particularly the last 15 yr., with applications wherever possible to human metabolism
and to diseases of the muscles and heart. The metabolism of these compounds
is discussed in relation to other metabolic processes, including carbohydrate metabolism,
muscular contraction, phosphate bond energy, phosphorylation and respiration,
physical fitness, nutritional muscular dystrophy, the vitamins, hormones, etc., and
creatine-creatinine metabolism in the myopathies and diseases of the heart. Detailed
instructions are presented for the determination of creatine and creatinine in body
tissues and fluids by the newer technics. An extensive bibliography is given, and
author and subject indexes are provided.
Corn oil and -butterfat essentially equal in growth-promoting value, L. P.
ZIALCITA, JR., and H. H. MITCHELL. (Univ. Ill.). (Science, 100 (1944), No. 2586,
pp. 60-62).-In extension of the somewhat controversial literature on the relative
nutritive value of butter and other fats (E. S. R., 89, pp. 757-760), both paired
feeding and ad libitum feeding experiments on young rats in a comparison of
butterfat and corn oil are summarized. "These studies indicate that, apart from
differences in vitamin content, corn oil and butterfat are essentially equal, in growth-.
promoting value for the rat."
Diet in relation to hepatic physiology and pathology: A review of pertinent
data, F. C. MANN (Jour. Amer. Dietet. Assoc., 19 (1943), No. 8, pp. 560-566).This
review of recent literature is presented under the headings: Diet in relation
to hepatic function, diet in relation to pathologic conditions of the liver, vitamins
and the liver, and protein and the liver. In addition to 16 references to the literature
cited in the text, a number of references are appended to relevant articles on the
functions of the liver; fatty liver, diet, etc.; and hepatic injury associated with
Observations on a diet deficient in both methionine and cystine in man, A. A.
ALBANESE, L. E. HOLT, JR., J. E. BRUMBACK, JR., J. E. FRANKSTON, and V. IRBY
(Bul. Johns Hopkins Hosp., 74 (1944), No. 5, pp. 308-312, illus. 1).-Two healthy
male subjects placed on a diet deficient in methionine and cystine developed negative
nitrogen balances shortly after institution of the doubly deficient diet. After 36
days on the diet, the nitrogen equilibrium was quickly restored by addition of a
supplement of methionine alone (18.8 mg. dl-methionine per kilo), suggesting
that methionine is capable of furnishing the entire requirements of man for sulfur
Ferritin.-VI, Conversion of inorganic and hemoglobin iron into ferritin iron
in the animal body. Storage function of ferritin iron as shown by radioactive
and magnetic measurements, P. F. HAHN, S. GRANICK, W. F. BALE, and
L. MICHAELIS (Jour. Biol. Chem., 150 (1943), No. 2, pp. 407-412).-Iron in the
form of ferric ammonium citrate when administered by vein to the dog was found
to be readily converted into ferritin iron in the liver. Iron derived from hemoglobin
