Ten adults with equal number of males and females, aged 17-32 years, were selected as experimental subjects. Cooked vegetable containing 3-4.5 mg of carotene was given to each subject daily for three consecutive days. The vegetables tested were spinach, colza, carrot, sweet potato, dehydrated colza and dehydrated carrot. An oil concentrate with a carotene content of 0.5 mg per ml prepared from the leaves of alfalfa in this laboratory was also tested.The average percentages of absorption of the ingested carotene from different sources were as follows: spinach 25.5%, colza 36.2%, carrot 27.4%, sweet potato 19.7% dehydrated colza 29.0% dehydrated carrot 36.7% and carotene concentrateIt had been shown that there was no significant effect on the absorption of carotene from vegetable by increasing oil supply in the diet. A daily intake of 16 g of vegetable oil for each subject was found to be sufficient for the absorption of carotene in the cooked vegetables. The increase of the oil consumption from 16 to 48 g daily did not improve the absorption of carotene.There was great variation in the result with different subjects and also with in different test peroids for the same subject on the same diet. Part of the variation may be attributed to the difference in carotene content among the servings resulting from uneven distribution of carotene in vegetables.

Various factors affect the development of headblight of wheat caused by Gibbe-rella zeae (Schw.) Petch under field conditions.The present investigation carriedout in 1955 and 1956 at Nanking,Kiangsu province,was primarily concerned withthe development of spores of the pathogen and the amount of rainfall in relationto disease development.For the purpose of inducing epiphytoties of the disease,asusceptible variety of wheat to headblight was grown in the inoculated plots.Inoculation was made at the surface of the soil with mycelium cultured on wheatgrain shortly after planting,and an "artificial rain" by frequent spray of water tothe plants was supplied after heading.Investigations were made on the develop-ment and dissemination of ascospores and conidia of the pathogen,the seasonaldevelopment of the disease and the meteorological factors involved. Field observations showed that the headblight fungus on the soil surface inthe inoculated plots produced both kinds of spores with ths ascospores much morepredominant than the conidia.Perithecia and mature ascospores could be formedboth in the fall and in next spring through early summer under conditions ofadequate moisture and warm temperature suitable for their development.It wasindicated by trapping the spores in the air that the ascospores produced on thesoil surface were the chief source of inoculum for primary infection although theconidia formed on the infected spikes were equally important in spreading the di-sease in the field later in the season.The frequency and amount of ascosporesand conidia present in the air depended upon the height in spore trapping.Whilespores were found most frequently and most abundantly at a height of 17 cm.above the ground,much less spores were caught at heights of 33 cm.and up to117 cm.There was a tendency to decrease in the amount of spores with theincrease in height.A comparative survey of the spores in the air in the inoculated ??and uninoculated plots indicated that a great majority of spores could not bedisseminated very far from their source of production.This,together with thefact that comparatively more spoies were trapped on raining days,made it rea-sonable to consider splashing rain as the more important agent than wind forspore dissemination. The amount of inoculum existing in the soil and the rainfall were proved tobe the factors of utmost importance for the epiphytotic of the disease.In 1955,the average percentages of headblight for the inoculated plots with and withoutthe spray of water were 29.4 and 13.4% respectively,in comparison with the neigh-bouring fields where only very few infected heads were observed.In 1956,theaverage percentages for headblight in the four experimental plots:(1) inoculatedand sprayed with water,(2) inoculated and not sprayed,(3) uninoculated andsprayed,and (4) uninoculated and not sprayed,were 42.98,42.05,11.91 and6.26%,respectively.In these four corresponding plots,the average percentagesfor culm rot were 4.27,3.89,3.65 and 2.17%.Although there was no significantdifference in the final percentages of both headblight and culm rot between thesprayed and unsprayed plots either with or without inoculation,probably due tothe continuous heavy rain in the latter part of the wheat-growing season,yethigher percentages were always observed in the sprayed plots than in the un-sprayed ones throughout the period of disease development.Under conditions ofabundant inoculum in the soil and heavy rainfall,increase in percentage of head-blight could reach as much as 32% within a period of two days even when theplants were already near maturity.In 1955,a daily average temperature over20℃ was found to be favorable for the development of headblight,but observa-tions made in 1956 did not show significant effect of the temperature on thedevelopment of disease.

The action of aureomycin on the respiration of Escherichia coli under different conditions was studied. Our results show that the respiration of Escherichia coli in ordinary broth or in media containing glucose together with some nitrogenous substance such as casein hydrolysate, alanine, aspartate, glutamate, glycine or ammonium sulfate, could be inhibited by aureomycin of minimal growth inhibiting concentration, namely 2.5 μg/ml.

The action of aureomycin on the respiration of Escherichia coli under different conditions was studied. Our results show that the respiration of Escherichia coli in ordinary broth or in media containing glucose together with some nitrogenous substance such as casein hydrolysate, alanine, aspartate, glutamate, glycine or ammonium sulfate, could be inhibited by aureomycin of minimal growth inhibiting concentration, namely 2.5 μg/ml. In the last case, the uptake of ammonium-nitrogen by the bacteria was also diminished. Aureomycin of concentrations lower than 100 μg/ml gave no significant effect on the oxygen consumption of the bacteria in a medium containing glucose and phosphate buffer only. Similar results were obtained with pyruvate substituted for glucose and with glutamate as nitrogen source, while with pyruvate alone the oxidation was only slightly depressed by aureomycin (2.5 μg/ml). Malate and acetate oxidations were not inhibited by such low concentration of the antibiotic. In control experiments addition of any of the above mentioned nitrogenous substances to the medium markedly increased the rate of the respiration over that observed for glucose or pyruvate alone, and this increase with the exception of glutamate could not be accounted for by the additional oxidation of the nitrogen containing substrates. In presence of 2.5 μg/ml of aureomycin, this enhancing action of the nitrogenous compounds was strongly depressed. The observed inhibition in case of the substrate mixture cannot be due to the action of the drug on the oxidation of the individual substrates, but is due to processes involving the combined metabolism of glucose (pyruvate) and any one of the nitrogenous compounds. From the fact that the inhibition is clearly noticeable within 15 minutes after the addition of aureomycin and can be observed under conditions in which growth does not take place, as judged from the respiration, it is suggested that aureomycin can inhibit some processes concerned with the oxidative nitrogen metabolism, preceding cell division, of Escherichia coil.

實驗結果表明最低制菌濃度的金黴素可以顯著抑制大腸桿菌在含有葡萄糖和某些合氮物如酪朊水解物、丙氨酸、門冬氨酸、谷氨酸、甘氨酸或硫酸銨的培養基中的呼吸,也抑制了氨氮的同化。在以丙酮酸和谷氨酸作底質時有同樣的現象。以上述含氮物中的任何一種加於大腸桿菌的葡萄糖磷酸鹽緩衝劑的懸浮液中,可以有力地提高其呼吸率,比在單獨葡萄糖中的要高得多。2.5微克/毫升的金黴素可以強烈地抑制這種提高作用。這種觀察到的抑制並不是由於個別底質分别受到抑制的結果。本文討論了金黴素抑制大腸桿菌呼吸的作用機構和可能的幾種解釋,並指出這種作用可能是由於金黴素抑制了包括碳水化物和含氮物在内的某個或某些聯合代謝過程。
