摘要:

Summary.The experiments here reported on treatment of spontaneous leukemia in mice with nitrogenized mustard gas — erasin — confirm the clinical results of such therapy insofar as they show a specific inhibitory effect on the leukotic tissue.Recovery of the animals was not aimed at, and probably it would not have been obtained either. But, at any rate, a complete remission may be said to have been obtained in those cases where all the organs examined were found to be free from tumor tissue, while the white blood count was brought down to a normal level.Possibly another series of experiments in which smaller doses of the remedy would be given for a considerable length of time, aiming at the recovery of the animals, might have given some different results. For the possibility cannot be excluded altogether that the large subtoxic doses perhaps have an inhibitory effect on the regenerative capacity of the organ

摘要:

Summary.The effect of adding to the drinking water unstimulated and untreated saliva from two human subjects who had markedly different caries susceptibility, on dental caries activity has been tested in hamsters. Three experimental groups were reared from weaning on the same cariogenic diet, the only dietary difference consisting in the quality of the drinking fluids. Group 1 received water mixed with saliva from a young female subject markedly caries‐susceptible. Group 2 was given water mixed with saliva from a young male subject markedly caries‐resistant, and group 3 received water alone.The results show that the animals which received saliva from the caries‐resistant subject exhibited less caries activity. It is therefore concluded that the saliva from the caries‐resistant individual contained a factor (or factors) which was able to decrease dental caries activity.Furthermore, these studies have demonstrated the existence in human saliva, at least in saliva of sexually mature individuals, of an unrecognized growth factor (or factors) which increase markedly the growth of hamsters, at least under the conditions of the present exp

摘要:

Summary.A pronounced relation is demonstrated between the dose of prophylactic and the antitoxin response within the doses covered by the present work.The size of the dose preferable for routine immunization is discussed in relationship to antigenicity and reactions.
