EFFECT OF ALCOHOL ON THE BLOOD

6:24 pm by Admin in Alcoholism

Dr. Richardson, in his lectures on alcohol, given both in England and America, speaking of the action of this substance on the blood after passing from the stomach, says:

“Suppose, then, a certain measure of alcohol be taken into the stomach, it will be absorbed there, but, previous to absorption, it will have to undergo a proper degree of dilution with water, for there is this peculiarity respecting alcohol when it is separated by an animal membrane from a watery fluid like the blood, that it will not pass through the membrane until it has become charged, to a given point of dilution, with water. It is itself, in fact, so greedy for water, it will pick it up from watery textures, and deprive them of it until, by its saturation, its power of reception is exhausted , after which it will diffuse into the current of circulating fluid.”

It is this power of absorbing water from every texture with which alcoholic spirits comes in contact, that creates the burning thirst of those who freely indulge in its use. Its effect, when it reaches the circulation, is thus described by Dr. Richardson:

“As it passes through the circulation of the lungs it is exposed to the air, and some little of it, raised into vapor by the natural heat, is thrown off in expiration. If the quantity of it be large, this loss may be considerable, and the odor of the spirit may be detected in the expired breath. If the quantity be small, the loss will be comparatively little, as the spirit will be held in solution by the water in the blood. After it has passed through the lungs, and has been driven by the left heart over the arterial circuit, it passes into what is called the minute circulation, or the structural circulation of the organism. The arteries here extend into very small vessels, which are called arterioles, and from these infinitely small vessels spring the equally minute radicals or roots of the veins, which are ultimately to become the great rivers bearing the blood back to the heart. In its passage through this minute circulation the alcohol finds its way to every organ. To this brain, to these muscles, to these secreting or excreting organs, nay, even into this bony structure itself, it moves with the blood. In some of these parts which are not excreting, it remains for a time diffused, and in those parts where there is a large percentage of water, it remains longer than in other parts. From some organs which have an open tube for conveying fluids away, as the liver and kidneys, it is thrown out or eliminated, and in this way a portion of it is ultimately removed from the body. The rest passing round and round with the circulation, is probably decomposed and carried off in new forms of matter.

“When we know the course which the alcohol takes in its passage through the body, from the period of its absorption to that of its elimination, we are the better able to judge what physical changes it induces in the different organs and structures with which it comes in contact. It first reaches the blood; but, as a rule, the quantity of it that enters is insufficient to produce any material effect on that fluid. If, however, the dose taken be poisonous or semi-poisonous, then even the blood, rich as it is in water and it contains seven hundred and ninety parts in a thousand is affected. The alcohol is diffused through this water, and there it comes in contact with the other constituent parts, with the fibrine, that plastic substance which, when blood is drawn, clots and coagulates, and which is present in the proportion of from two to three parts in a thousand; with the albumen which exists in the proportion of seventy parts; with the salts which yield about ten parts; with the fatty matters; and lastly, with those minute, round bodies which float in myriads in the blood (which were discovered by the Dutch philosopher, Leuwenhock, as one of the first results of microscopical observation, about the middle of the seventeenth century), and which are called the blood globules or corpuscles. These last-named bodies are, in fact, cells; their discs, when natural, have a smooth outline, they are depressed in the centre, and they are red in color; the color of the blood being derived from them. We have discovered that there exist other corpuscles or cells in the blood in much smaller quantity, which are called white cells, and these different cells float in the blood-stream within the vessels. The red take the centre of the stream; the white lie externally near the sides of the vessels, moving less quickly. Our business is mainly with the red corpuscles. They perform the most important functions in the economy; they absorb, in great part, the oxygen which we inhale in breathing, and carry it to the extreme tissues of the body; they absorb, in great part, the carbonic acid gas which is produced in the combustion of the body in the extreme tissues, and bring that gas back to the lungs to be exchanged for oxygen there; in short, they are the vital instruments of the circulation.

“With all these parts of the blood, with the water, fibrine, albumen, salts, fatty matter and corpuscles, the alcohol comes in contact when it enters the blood, and, if it be in sufficient quantity, it produces disturbing action. I have watched this disturbance very carefully on the blood corpuscles; for, in some animals we can see these floating along during life, and we can also observe them from men who are under the effects of alcohol, by removing a speck of blood, and examining it with the microscope. The action of the alcohol, when it is observable, is varied. It may cause the corpuscles to run too closely together, and to adhere in rolls; it may modify their outline, making the clear-defined, smooth, outer edge irregular or crenate, or even starlike; it may change the round corpuscle into the oval form, or, in very extreme cases, it may produce what I may call a truncated form of corpuscles, in which the change is so great that if we did not trace it through all its stages, we should be puzzled to know whether the object looked at were indeed a blood-cell. All these changes are due to the action of the spirit upon the water contained in the corpuscles; upon the capacity of the spirit to extract water from them. During every stage of modification of corpuscles thus described, their function to absorb and fix gases is impaired, and when the aggregation of the cells, in masses, is great, other difficulties arise, for the cells, united together, pass less easily than they should through the minute vessels of the lungs and of the general circulation, and impede the current, by which local injury is produced.

“A further action upon the blood, instituted by alcohol in excess, is upon the fibrine or the plastic colloidal matter. On this the spirit may act in two different ways, according to the degree in which it affects the water that holds the fibrine in solution. It may fix the water with the fibrine, and thus destroy the power of coagulation; or it may extract the water so determinately as to produce coagulation.”

ALCOHOL HAS NO FOOD VALUE

6:23 pm by Admin in Alcoholism

Alcohol has no food value and is exceedingly limited in its action as a remedial agent. Dr. Henry Monroe says, “every kind of substance employed by man as food consists of sugar, starch, oil and glutinous matter mingled together in various proportions. These are designed for the support of the animal frame. The glutinous principles of food fibrine, albumen and casein are employed to build up the structure while the oil, starch and sugar are chiefly used to generate heat in the body”.

Now it is clear that if alcohol is a food, it will be found to contain one or more of these substances. There must be in it either the nitrogenous elements found chiefly in meats, eggs, milk, vegetables and seeds, out of which animal tissue is built and waste repaired or the carbonaceous elements found in fat, starch and sugar, in the consumption of which heat and force are evolved.

“The distinctness of these groups of foods,” says Dr. Hunt, “and their relations to the tissue-producing and heat-evolving capacities of man, are so definite and so confirmed by experiments on animals and by manifold tests of scientific, physiological and clinical experience, that no attempt to discard the classification has prevailed. To draw so straight a line of demarcation as to limit the one entirely to tissue or cell production and the other to heat and force production through ordinary combustion and to deny any power of interchangeability under special demands or amid defective supply of one variety is, indeed, untenable. This does not in the least invalidate the fact that we are able to use these as ascertained landmarks”.

How these substances when taken into the body, are assimilated and how they generate force, are well known to the chemist and physiologist, who is able, in the light of well-ascertained laws, to determine whether alcohol does or does not possess a food value. For years, the ablest men in the medical profession have given this subject the most careful study, and have subjected alcohol to every known test and experiment, and the result is that it has been, by common consent, excluded from the class of tissue-building foods. “We have never,” says Dr. Hunt, “seen but a single suggestion that it could so act, and this a promiscuous guess. One writer (Hammond) thinks it possible that it may ’somehow’ enter into combination with the products of decay in tissues, and ‘under certain circumstances might yield their nitrogen to the construction of new tissues.’ No parallel in organic chemistry, nor any evidence in animal chemistry, can be found to surround this guess with the areola of a possible hypothesis”.

Dr. Richardson says: “Alcohol contains no nitrogen; it has none of the qualities of structure-building foods; it is incapable of being transformed into any of them; it is, therefore, not a food in any sense of its being a constructive agent in building up the body.” Dr. W.B. Carpenter says: “Alcohol cannot supply anything which is essential to the true nutrition of the tissues.” Dr. Liebig says: “Beer, wine, spirits, etc., furnish no element capable of entering into the composition of the blood, muscular fibre, or any part which is the seat of the principle of life.” Dr. Hammond, in his Tribune Lectures, in which he advocates the use of alcohol in certain cases, says: “It is not demonstrable that alcohol undergoes conversion into tissue.” Cameron, in his Manuel of Hygiene, says: “There is nothing in alcohol with which any part of the body can be nourished.” Dr. E. Smith, F.R.S., says: “Alcohol is not a true food. It interferes with alimentation.” Dr. T.K. Chambers says: “It is clear that we must cease to regard alcohol, as in any sense, a food”.

“Not detecting in this substance,” says Dr. Hunt, “any tissue-making ingredients, nor in its breaking up any combinations, such as we are able to trace in the cell foods, nor any evidence either in the experience of physiologists or the trials of alimentarians, it is not wonderful that in it we should find neither the expectancy nor the realization of constructive power.”

Not finding in alcohol anything out of which the body can be built up or its waste supplied, it is next to be examined as to its heat-producing quality.

Production of heat.
——————

“The first usual test for a force-producing food,” says Dr. Hunt, “and that to which other foods of that class respond, is the production of heat in the combination of oxygen therewith. This heat means vital force, and is, in no small degree, a measure of the comparative value of the so-called respiratory foods. If we examine the fats, the starches and the sugars, we can trace and estimate the processes by which they evolve heat and are changed into vital force, and can weigh the capacities of different foods. We find that the consumption of carbon by union with oxygen is the law, that heat is the product, and that the legitimate result is force, while the result of the union of the hydrogen of the foods with oxygen is water. If alcohol comes at all under this class of foods, we rightly expect to find some of the evidences which attach to the hydrocarbons.”

What, then, is the result of experiments in this direction? They have been conducted through long periods and with the greatest care, by men of the highest attainments in chemistry and physiology, and the result is given in these few words, by Dr. H.R. Wood, Jr., in his Materia Medica. “No one has been able to detect in the blood any of the ordinary results of its oxidation.” That is, no one has been able to find that alcohol has undergone combustion, like fat, or starch, or sugar, and so given heat to the body.

Alcohol and reduction of temperature.
————————————

instead of increasing it; and it has even been used in fevers as an anti-pyretic. So uniform has been the testimony of physicians in Europe and America as to the cooling effects of alcohol, that Dr. Wood says, in his Materia Medica, “that it does not seem worth while to occupy space with a discussion of the subject.” Liebermeister, one of the most learned contributors to Zeimssen’s Cyclopaedia of the Practice of Medicine, 1875, says: “I long since convinced myself, by direct experiments, that alcohol, even in comparatively large doses, does not elevate the temperature of the body in either well or sick people.” So well had this become known to Arctic voyagers, that, even before physiologists had demonstrated the fact that alcohol reduced, instead of increasing, the temperature of the body, they had learned that spirits lessened their power to withstand extreme cold. “In the Northern regions,” says Edward Smith, “it was proved that the entire exclusion of spirits was necessary, in order to retain heat under these unfavorable conditions.”

Alcohol does not make you strong.
——————————–

If alcohol does not contain tissue-building material, nor give heat to the body, it cannot possibly add to its strength. “Every kind of power an animal can generate,” says Dr. G. Budd, F.R.S., “the mechanical power of the muscles, the chemical (or digestive) power of the stomach, the intellectual power of the brain accumulates through the nutrition of the organ on which it depends.” Dr. F.R. Lees, of Edinburgh, after discussing the question, and educing evidence, remarks: “From the very nature of things, it will now be seen how impossible it is that alcohol can be strengthening food of either kind. Since it cannot become a part of the body, it cannot consequently contribute to its cohesive, organic strength, or fixed power; and, since it comes out of the body just as it went in, it cannot, by its decomposition, generate heat force.”

Sir Benjamin Brodie says: “Stimulants do not create nervous power; they merely enable you, as it were, to use up that which is left, and then they leave you more in need of rest than before.”

Baron Liebig, so far back as 1843, in his “Animal Chemistry,” pointed out the fallacy of alcohol generating power. He says: “The circulation will appear accelerated at the expense of the force available for voluntary motion, but without the production of a greater amount of mechanical force.” In his later “Letters,” he again says: “Wine is quite superfluous to man, it is constantly followed by the expenditure of power” whereas, the real function of food is to give power. He adds: “These drinks promote the change of matter in the body, and are, consequently, attended by an inward loss of power, which ceases to be productive, because it is not employed in overcoming outward difficulties i.e., in working.” In other words, this great chemist asserts that alcohol abstracts the power of the system from doing useful work in the field or workshop, in order to cleanse the house from the defilement of alcohol itself.

The late Dr. W. Brinton, Physician to St. Thomas’, in his great work on Dietetics, says: “Careful observation leaves little doubt that a moderate dose of beer or wine would, in most cases, at once diminish the maximum weight which a healthy person could lift. Mental acuteness, accuracy of perception and delicacy of the senses are all so far opposed by alcohol, as that the maximum efforts of each are incompatible with the ingestion of any moderate quantity of fermented liquid. A single glass will often suffice to take the edge off both mind and body, and to reduce their capacity to something below their perfection of work.”

Dr. F.R. Lees, F.S.A., writing on the subject of alcohol as a food, makes the following quotation from an essay on “Stimulating Drinks,” published by Dr. H.R. Madden, as long ago as 1847: “Alcohol is not the natural stimulus to any of our organs, and hence, functions performed in consequence of its application, tend to debilitate the organ acted upon.

Alcohol is incapable of being assimilated or converted into any organic proximate principle, and hence, cannot be considered nutritious.

The strength experienced after the use of alcohol is not new strength added to the system, but is manifested by calling into exercise the nervous energy pre-existing.

The ultimate exhausting effects of alcohol, owing to its stimulant properties, produce an unnatural susceptibility to morbid action in all the organs, and this, with the plethora superinduced, becomes a fertile source of disease.

A person who habitually exerts himself to such an extent as to require the daily use of stimulants to ward off exhaustion, may be compared to a machine working under high pressure. He will become much more obnoxious to the causes of disease, and will certainly break down sooner than he would have done under more favorable circumstances.

The more frequently alcohol is had recourse to for the purpose of overcoming feelings of debility, the more it will be required, and by constant repetition a period is at length reached when it cannot be foregone, unless reaction is simultaneously brought about by a temporary total change of the habits of life.

Driven to the wall.
——————

Not finding that alcohol possesses any direct alimentary value, the medical advocates of its use have been driven to the assumption that it is a kind of secondary food, in that it has the power to delay the metamorphosis of tissue. “By the metamorphosis of tissue is meant,” says Dr. Hunt, “that change which is constantly going on in the system which involves a constant disintegration of material; a breaking up and avoiding of that which is no longer aliment, making room for that new supply which is to sustain life.” Another medical writer, in referring to this metamorphosis, says: “The importance of this process to the maintenance of life is readily shown by the injurious effects which follow upon its disturbance. If the discharge of the excrementitious substances be in any way impeded or suspended, these substances accumulate either in the blood or tissues, or both. In consequence of this retention and accumulation they become poisonous, and rapidly produce a derangement of the vital functions. Their influence is principally exerted upon the nervous system, through which they produce most frequent irritability, disturbance of the special senses, delirium, insensibility, coma, and finally, death.”

“This description,” remarks Dr. Hunt, “seems almost intended for alcohol.” He then says: “To claim alcohol as a food because it delays the metamorphosis of tissue, is to claim that it in some way suspends the normal conduct of the laws of assimilation and nutrition, of waste and repair. A leading advocate of alcohol (Hammond) thus illustrates it: ‘Alcohol retards the destruction of the tissues. By this destruction, force is generated, muscles contract, thoughts are developed, organs secrete and excrete.’ In other words, alcohol interferes with all these. No wonder the author ‘is not clear’ how it does this, and we are not clear how such delayed metamorphosis recuperates.

Not an originator of vital force.
——————————–

which is not known to have any of the usual power of foods, and use it on the double assumption that it delays metamorphosis of tissue, and that such delay is conservative of health, is to pass outside of the bounds of science into the land of remote possibilities, and confer the title of adjuster upon an agent whose agency is itself doubtful.

Having failed to identify alcohol as a nitrogenous or non-nitrogenous food, not having found it amenable to any of the evidences by which the food-force of aliments is generally measured, it will not do for us to talk of benefit by delay of regressive metamorphosis unless such process is accompanied with something evidential of the fact something scientifically descriptive of its mode of accomplishment in the case at hand, and unless it is shown to be practically desirable for alimentation.

There can be no doubt that alcohol does cause defects in the processes of elimination which are natural to the healthy body and which even in disease are often conservative of health.

ACTION OF ALCOHOL ON INTERNAL ORGANS

6:22 pm by Admin in Alcoholism

Action on the stomach.
———————-

The action of alcohol on the stomach is extremely dangerous that it becomes unable to produce the natural digestive fluid in sufficient quantity and also fails to absorb the food which it may imperfectly digest. A condition marked by the sense of nausea emptiness, prostration and distention will always be faced by an alcoholic. This results in a loathing for food and is teased with a craving for more drink. Thus there is engendered a permanent disorder which is called dyspepsia. The disastrous forms of confirmed indigestion originate by this practice.

How the liver gets affected.
—————————-

The organic deteriorations caused by the continued use of alcohol are often of a fatal character. The organ which most frequently undergoes structural changes from alcohol, is the liver. Normally, the liver has the capacity to hold active substances in its cellular parts. In instances of poisoning by various poisonous compounds, we analyse liver as if it were the central depot of the foreign matter. It is practically the same in respect to alcohol. The liver of an alcoholic is never free from the influence of alcohol and it is too often saturated with it. The minute membranous or capsular structure of the liver gets affected, preventing proper dialysis and free secretion. The liver becomes large due to the dilatation of its vessels, the surcharge of fluid matter and the thickening of tissue. This follows contraction of membrane and shrinking of the whole organ in its cellular parts. Then the lower parts of the alcoholic becomes dropsical owing to the obstruction offered to the returning blood by the veins. The structure of the liver may be charged with fatty cells and undergo what is technically designated ‘fatty liver’.

How the Kidneys deteriorate.
—————————-

The Kidneys also suffer due to the excessive consumption of alcohol. The vessels of Kidneys lose elasticity and power of contraction. The minute structures in them go through fatty modification. Albumin from the blood easily passes through their membranes. This results in the body losing its power as if it were being run out of blood gradually.

Congestion of the lungs.
————————

Alcohol relaxes the vessels of the lungs easily as they are most exposed to the fluctuations of heat and cold. When subjected to the effects of a rapid variation in atmospheric temperature, they get readily congested. During severe winter seasons, the suddenly fatal congestions of lungs easily affects an alcoholic.

Alcohol weakens the heart.
————————–

Consumption of alcohol greatly affects the heart. The quality of the membraneous structures which cover and line the heart changes and are thickened, become cartilaginous or calcareous. Then the valves lose their suppleness and what is termed valvular disorder becomes permanent. The structure of the the coats of the great blood-vessel leading from the heart share in the same changes of structure so that the vessel loses its elasticity and its power to feed the heart by the recoil from its distention, after the heart, by its stroke, has filled it with blood.

Again, the muscular structure of the heart fails owing to degenerative changes in its tissue. The elements of the muscular fibre are replaced by fatty cells or, if not so replaced, are themselves transferred into a modified muscular texture in which the power of contraction is greatly reduced.

Those who suffer from these organic deteriorations of the central and governing organ of the circulation of the blood learn the fact so insidiously, it hardly breaks upon them until the mischief is far advanced. They are conscious of a central failure of power from slight causes such as overexertion, trouble, broken rest or too long abstinence from food. They feel what they call a ’sinking’ but they know that wine or some other stimulant will at once relieve the sensation. Thus they seek to relieve it until at last they discover that the remedy fails. The jaded, overworked, faithful heart will bear no more. it has run its course and the governor of the blood-streams broken. The current either overflows into the tissues gradually damming up the courses or under some slight shock or excess of motion ceases wholly at the centre.
