Abstract
1. Distilled water employed intravenously failed to initiateantisheep hemolytic sensitizer production.
2. Without exception,a dose was found for each agency withwhich it was attemptedto call forth increased sensitizer productionthat brought thedesired result The same was also true as regardsthe elicitationof depression. Both protein and nonprotein agencieswere used.Hypotonic, isotonic and hypertonic agencies wereincluded.
3.Weekly bleeding apparently exerted no appreciable influenceon sensitizer production.
4. Among the doses calling forthincreased sensitizer production,it was always the larger dosethat called forth the greaterproduction.
5. The productionof sensitizer following the use of the samedosage amount whenemployed subsequent to two sheep cell injectionsexceeded strikinglythat following its use subsequent to onlya single dose.
6.The dose used to elicit depression exceeded considerablythatemployed in eliciting increased production.
7. The amountof sensitizer produced when water and water containingincreasingamounts of salts were injected subsequent to sheepcell injection,was inversely proportional to the amount ofsalt contained.
8. There was no appreciable difference in the production betweenwater injection on the one hand and Ringer's solution and normalsaline on the other. Nor was there any appreciable differencein the results obtained with saline on the one hand and salinecontaining the microörganisms in quantity to make the typhoid-paratyphoidagency on the other.
