In such diseases as pneumonia and tuberculosis, the white cells, according to Wright, cannot effectually combat the germs unless there are plenty of opsonins present to aid them. Now, in treating pneumonia and tuberculosis, many practitioners encourage the use of alcohol. Dr. Stewart believed that alcohol was injurious. Having heard Sir W. Edward Wright’s lectures, he asked himself the question:
“Can the evil effects of alcohol be due to its lowering of the opsonic power of the blood?”
He instituted a series of experiments to determine, if possible, the facts in the case. He first of all administered to four persons who all their lives had been total abstainers, two ounces each of port wine. The normal opsonic power of each of these individuals had been determined as being 75 or above—that is to say, it was well above the point at which the opsonic power must be maintained in order that the white cell may do effective fighting. At the time when the subjects took the port wine, the first subject had a normal amount of opsonic power to resist the germ of tuberculosis which may be expressed by the term 1.13., and a normal power of resistance to the pus germ, which infects wounds, of 1.06. After drinking the wine, both those powers of resistance were lowered most perceptibly; the first to .85, and the second to .67. Similar results, in greater or less degree, followed in all other cases. The port wine decreased the power of the blood to make opsonic sauce for the white cells.
In a second series of experiments, two ounces of Scotch whisky were taken an hour apart; that is, the normal index was taken, and immediately afterwards an ounce of the Scotch whisky was taken, an hour later another ounce, and an hour after this the index was taken again. The results here were similar. For the germs of tuberculosis it was discovered that the opsonic power had dropped 10% and for the streptococci (or pus-forming) germs about 8%.
In another experiment where two ounces of sherry wine were used, the opsonic power for the germs of tuberculosis dropped 11% and for the streptococci 5%.
In another experiment where four ounces of champagne were taken, the opsonic power dropped 9% for the germs of tuberculosis and 19% for the streptococci germ. Many other experiments were performed, but they gave practically the same results. The opsonic power decreased in proportion to the amount of alcohol contained in the liquor.
Dr. Stewart carried on his experiments in the laboratory of the Battle Creek Sanitarium, with the assistance of Dr. A. W. Nelson. He reported his results to the American Society for the Study of Alcohol and Drug Neuroses:
“I realize that there are a great number of factors which influence the opsonic power of the blood, and that there is considerable variation in even what may be considered normal cases, but, notwithstanding these variations, there is a sufficient uniformity to enable us to make some very valuable deductions. I feel justified in concluding that alcohol has a marked influence in reducing the vital forces of the body, thereby greatly interfering with the natural power of the body to remedy ailments. Since Wright has shown that out of all comparison the most valuable asset in medicine lies in raising the anti-bacterial power of the blood, the adminstration of alcohol, which according to these experiments, is pro-bacterial, and as such a strong liability instead of an asset, should be eliminated from our therapeutics, at least so far as internal administration in infectious diseases is concerned.
“While only a comparatively few experiments have been made, the results obtained have been uniform, and justify, I believe, the preliminary report of it given to the medical profession and the public with the hope that it may encourage others to pursue the work further in this direction.
“Heretofore, when any statement was made to the effect that alcohol caused this or the other disease, or ailment, or harmful effect of any sort on the human constitution, the reply could be and was made that the case could not be proven; that there were always circumstances which might be construed as showing that other factors besides alcohol influenced the situation. Now, however, I believe that we have opened up a line of investigation which will place the proofs against alcohol on a solid scientific basis by demonstrating its injurious effect on the blood, which is the life.”
