摘要:

There is generally a truth underlying an old-fashioned country saying, such as “After dinner rest awhile, after supper walk a mile,” for it has been founded upon the experience of a large number of individuals of many generations. It is interesting to obtain verification, if it be possible, by controlled experiments. This we have attempted to do both with animals and man. The general view expressed in the saying is that hard muscular work performed too soon after a meal gives rise to digestive trouble and inefficient performance. The farmer insisted that his carter came early in the morning to feed his horses in time to allow an adequate interval before they started hard work in the fields. The trainers of athletes, race-horses and whippets recognised the importance of this saying, and intelligent labourers paid by the piece found that taking an hour off for the mid-day meal made for efficiency and well-being. The only organised transgression of the rule on a large scale appears to be found in schools, where the boys usually have a big mid-day meal and are turned out for compulsory games too soon afterwards. The bad results may not be so obvious in the young, for their bodies are more plastic and capable of more rapid adjustment than are those of adults.

摘要:

Domesticated white and black-and-white rats have been found suitable for experiment. Many observations were made upon tame mice, but it is more difficult to train them to remain quiet during the exposure to the X rays, and the rate of passage of the food through the alimentary canal is more rapid; moreover, they are more delicate than rats. One hundred and thirteen skiagrams of the animals have been obtained, and many of these include pictures of two or three rats or six or eight mice.The apparatus used in the investigation consisted of an X-ray tube of the gas type, a 12-inch induction coil by Watson and Sons, a mercury break, and an Andrews “Raold” valve. In this form of valve one of the electrodes is a concave disc of aluminium and the other a metal cylinder with an expanded extremity. This set of apparatus was used first in 1912 by A. F. Hurst in his research on the movements of the alimentary canal, and was presented by him to the Physiological Department of Guy's Hospital. For our investigations on small animals the apparatus was adequate, and exposures from 0·5 to 1 second were used, but for man exposures as long as 4 seconds were necessary. These long exposures in some cases produced imperfect skiagrams of the stomach owing to peristaltic movements.

摘要:

Uroselectan B, a product of Schering-Kahlbaum, has been placed on the market as an improved version of the firm's original uroselectan. The authors investigated the action of the latter and of abrodil on animals, and have repeated the work with this new product. As far as possible, the work has been carried out on the same lines as before, with such modifications as were necessary.The drug is stated to be the disodium salt of 3·5-diiodo-4-oxy-N-methyl-pyridine-2·6-dicarboxylic acid. Its molecular weight is 493 and it contains about 51 per cent of iodine. It is extremely soluble in water and is put up for use in ampoules, each containing 15 gm. of the drug dissolved in sufficient 10 per cent glucose solution to give a volume of 20 c.c.Except for a few allusions to its use in clinical practice very little appears to have been published concerning uroselectan B. In a lecture to the Surgical Section of the Royal Society of Medicine, v. Lichtenberg gave the results of certain experiments on animals and the determination of the minimum lethal dose for rats and rabbits, and made a bare mention of experiments on the frog heart. Apart from this we have been unable to find any account of a pharmacological investigation of the action of this drug.

摘要:

Dr. Russell Reynolds delivered his presidential address to this section on October 21. He chose as his subject “Radiology at the Present Day,” and began with a historical account of the development of the speciality in which he had been actively engaged since 1898. He said that it was not too much to claim that radiology now occupied the most important position in the whole realm of medical science, and that it was rapidly extending its influence into the realms of pure science. During the last few years it had revolutionised ideas of diagnosis, and a true “exploratory laparotomy” was now exceptional. Types of tube had varied greatly, but the first great advance on the models of 1901 had been the hot cathode tube brought out by Dr. W. G. Coolidge in 1913. In 1925 Dr. Bouwers, of Holland, had introduced a very different design which carried protective screens in the tube itself: the Metalix pattern The modern tube was very strongly constructed and could carry very large currents, the apparatus also combining compactness and elasticity in use with the necessary protection. The old induction coil had been replaced by the transformer, and constant potential generators were coming into favour. Accessory apparatus was constantly being improved. Teleradiography was of the greatest value in the examination of certain organs, particularly in the thorax, and would be advantageous if used for all parts of the body.

摘要:

The Hon Editors, TheBritishJournalof Radiology.It is evident that Dr. Shanks is unaware of the fact that thallium acetate treatment of ringworm of the scalp is a recognised and routine dermatological practice in a very great number of centres in Great Britain, and in other countries. Alternatively, he is of the opinion that medical practitioners who use thallium acetate—exercising the same care and precautions as are necessary in the employment of numerous other drugs in daily use by the majority of medical men—are a danger to the community.
