“With regard to the predisposing influence of the alcohol, one is constrained to believe that it is in most cases the result of structural alterations consequent upon its direct action on the tissues, though in a number of animals no such alterations could be made out by microscopic examinations. I am inclined, however, to the belief, in the light of the work of Berkley and Friedenwald, done under the direction of Professor Welch, in the pathological laboratory of the Johns Hopkins University, that a closer study of the tissues of these animals would have revealed in all of them structural changes of such a nature as to indicate disturbances of important vital functions of sufficient gravity fully to account for the loss of normal resistance.
“Following up Dr. Abbott’s experiments, Dr. Deléarde, working in Calmette’s laboratory in the Institut Pasteur at Lille, made a series of observations which are, from many points of view, of very great interest and importance as he attacks it from an entirely new standpoint, one that will, I hope, ere long, be taken up by those working in this country. It has already been demonstrated that ‘alcoholics’ suffer far more seriously from microbic affections than do those of sober life, and it is now accepted that amongst them the mortality from this class of disease is higher than amongst those who are not accustomed to take alcohol regularly or to excess.
“It is pointed out, as most of us have from time to time had the opportunity of observing, that, taking pneumonia as an example of this class of disease, there can be no doubt that the alcoholic patient has not merely an appreciably smaller chance for recovery, but an apparently slight attack becomes one in which the chances of recovery come to be against the patient rather than in his favor. I well remember when I was House Physician in the Royal Infirmary at Edinburgh that Dr. Muirhead, who almost invariably treated his pneumonic patients without alcohol, used to say that an ordinary case of acute pneumonia should always recover under careful treatment, but that cases of pneumonia in ‘alcoholics’ were always most anxious cases and in every way unsatisfactory. (Slides were shown on screen to illustrate the changes taking place in pneumonia, the conditions of leucocytosis, and the very important part which leucocytes play in the process of ‘clearing up’ during the course of the patient’s recovery). Dr. Deléarde in an admirable summary gives the principal features of pneumonia in alcoholics. He describes it as running a comparatively prolonged course, as being often accompanied by a violent delirium, following which is a period of prostration or of coma; even in those who recover, abscesses frequently occur in the liver, or in other organs. He also points out that there may be a similar chain of events in other infective conditions such as erysipelas and typhoid fever, but as he insists that, until Abbott’s experiments on the streptococcus,[A] staphylococcus[A] and bacterium coli,[A] in alcoholized and non-alcoholized animals, little attempt has been made to indicate the mechanism, or, at any rate, the process by which alcoholized individuals are rendered more susceptible to the invasion and action of micro-organisms.

“As we have already seen, Abbott’s experiments prove beyond doubt that attenuated disease-producing organisms, which in healthy animals do not kill immediately, bring about a fatal result when the animal has previously been treated with alcohol. In order to determine which was the most important factor in the destruction or weakening of the resisting agents in the body, Dr. Deléarde conceived the idea of experimenting with those diseases in which it has been found possible to produce, artificially, as it were, and under controlled conditions, an immunity or insusceptibility in healthy animals. He carried out a series of experiments on rabbits, immunizing against and infecting with the virus of hydrophobia, tetanus and anthrax.[B] To these rabbits he first administered a quantity of alcohol, from 6 to 8 c.c. at first, and gradually rises to 10 c.c. doses per diem.

“There is in the first instance a slight falling off in weight of the animal, but after a time this ceases, and the animal may again become heavier, until the original weight is reached. He then took a series of animals and vaccinated them against hydrophobia. In one set the animals were afterwards alcoholized and then injected with a considerable quantity of virulent rabic cord. It was here found that immunity against rabies had not been lost.
“In a second set the vaccination and alcoholization were carried on simultaneously, a fatal dose (as proved by control experiment) of rabic cord was then injected, when it was found that little or no immunity had been acquired. In a third series the alcohol was stopped before the immunizing process was commenced. In this case marked immunity was acquired.
“As regards rabies, then, acute alcoholism, especially when continued for comparatively short periods, simply has the effect of preventing the acquisition of immunity when alcohol is administered during the period when the immunizing process ought to be going on. This indicates that the action of the alcohol in acute alcoholism is direct, and that although its administration prevents the acquisition of immunity it does not alter the cells so materially that they cannot regain some of their original powers, whilst once the immunity has been gained by the cells, alcohol cannot, immediately, so fundamentally alter them that they lose the immunity they have already acquired. When we come to the consideration of the case of tetanus, however, we are carried a step further. Dr. Deléarde repeating his immunizing and alcoholizing experiments, but now working with tetanus virus in place of rabic virus, found—and, perhaps, here it may be as well to give his own words:—
(1) “‘That animals vaccinated against tetanus and afterwards alcoholized lose their immunity against tetanus;
(2) “‘That animals vaccinated against tetanus and at the same time alcoholized do not readily acquire immunity;
(3) “‘That animals first alcoholized and then vaccinated may acquire immunity against tetanus if alcohol is suppressed from the commencement of the process of vaccination.’
“In the case of anthrax too, as we gather from another series of experiments, it is almost impossible to confer immunity, if the animal is alcoholized during the time that it is being vaccinated, and although the animals, first alcoholized and then vaccinated, may acquire a certain amount of immunity, they rapidly lose condition and are certainly more ill than non-alcoholized animals vaccinated simultaneously.
“We have already mentioned that Massart and Bordet some years ago pointed out that alcohol, even in very dilute solutions, exerts a very active negative chemiotaxis, i. e., it appears to have properties by which leucocytes are repelled or driven away from its neighborhood and actions. Alcohol thus prevents the cells from attacking invading bodies or of reacting in the presence of the toxins which also, as is well known, exert a more or less marked negative chemiotaxis, i.e., the cells appear to be paralyzed. In all diseases, then, in which the leucocytes help to remove an invading organism or in which they have the power of reacting or of carrying on their functions in the presence of a toxin, we should expect that alcohol would to a certain extent deprive them of this power or interfere with their capacity for acquiring a greater resisting power or of reinforcing the powers of resistance. It appears indeed to reinforce the poison formed by pathogenic organisms. Dr. Deléarde maintains moreover that chronic alcoholism increases enormously the difficulty of rendering an animal immune to anthrax, whilst as those who have had any experience of cases of anthrax know full well alcoholics, whether acute or chronic, manifest a remarkable susceptibility both as regards attacks of anthrax and the fatality of the disease when once contracted. Further as clinical proof of the correctness of another of these sets of experiments, Dr. Deléarde instances two cases of rabies which have come under observation in the Institut Pasteur—one, a man of 30 years of age, of intemperate habits who after a complete treatment of 18 days after a bite in the hand died of hydrophobia; the other, a child of 13 years who was bitten on the face by the same dog that had attacked the other patient, and on the same day—who underwent the same treatment remained perfectly well. In this case the more severe bite (the face being the most serious position in which a person can be bitten) was received by the child; indeed the intemperate habits of the man, who even took alcohol during treatment, appear to have been the only more serious factor in his case as compared with that of the child.
“From all this Dr. Deléarde draws the practical conclusion that patients who have been bitten by a mad dog should as far as possible abstain from the use of alcohol not only during the process of treatment, but also for some time afterwards, even for a period of eight months, during which period, apparently, increase of immunity may be going on. Beyond this he maintains that doctors often commit a grave error in administering strong doses of alcohol to patients suffering from certain infectious diseases such as pneumonia, or from certain intoxications such as those produced by snake-bite, during which an increase in the number of leucocytes appear to be a necessary part of any process that leads to the cure of the patient. Finally, he points out how necessary it is that we should respect the integrity of the leucocytes in the presence of microbic infections or intoxications. We may accept these statements all the more readily as Dr. Deléarde states that ‘although we must recognize that small doses of dilute alcoholic beverages are indicated in certain cases where it is necessary to stimulate the nervous system, one must guard oneself against an abuse which may certainly be prejudicial to the putting into operation of the mechanism of defence against the organisms of disease.’
“In so far as these conclusions rest on a series of exact experiments we are justified in accepting them as being a most valuable contribution to the question; where there is no experimental basis, we must exercise our own judgment. To show the very strong impression that exists that there is some connection between severe cases of pneumonia and alcohol I may mention that the other day I heard a gentleman (not a medical man) say, ‘It is well known that most men (of a certain profession) die from alcoholism.’ When asked to explain he said, ‘They all die from cirrhosis or pneumonia, and if those conditions are not due to alcoholism, what is?’
“There can be no doubt that in addition to its specific action, alcohol has a general action—the mal-nutrition, which is usually associated with the use of alcohol, especially as a result of its action on the mucous membranes of the stomach, etc.”
That the “guardian cells” of the body play a part in a considerable number of diseases was illustrated by Dr. Woodhead by drawings and photographs, shown on the lantern screen. The photographs included cells containing anthrax, typhoid and tubercle bacilli, the spirilla of relapsing fever, specimens from cases of anthrax. Specimens were shown in which the cells were actually ingesting and digesting the specific micro-organisms. In a case of typhoid, showing large masses of
