Biochemists have been trying for a long time to figure out precisely how and where all of this response takes place. Enzymes – with simple names such as nicotinamide, adenine, dinucleotide, and alcohol dehydrogenase – play big roles in the response; but the metabolic pathways and the specific mechanism of action haven’t yet been attained with certitude, not by any stretch of the imagination. Pharmacologists classify alcohol as an anesthetic – it’s closely related to the ether, chemically. That’s a tiny shock, isn’t it? Consider convincing the local bartender that he’s making a living pushing an anesthetic! It’s a fact, nonetheless. Alcohol follows the traditional pattern of an anesthetic. It provides a euphoric state, then hypnosis, and finally deep narcosis.
Many moons ago, alcohol was the drug-of-choice for anesthesia. Until chloroform came along in 1847, it was all that was available. You must have seen at least one of those sterling Hollywood films, where the doctor patiently waited until his subject was completely plastered and then proceeded very adroitly to eliminate two arrows, four bullets, a tomahawk and, for an encore, the left arm, and right leg. Alcohol is a very poor anesthetic. The period of anesthesia is extremely short, and the respiratory collapse that looms ominously around the corner is not very desirable. То рut іt аnоthеr wау, іf аll thе anesthetists had to work with was alcohol, malpractice insurance would be out of sight.
Let’s research the anesthetic value of the drug. The nerve fibers in our bodies are joined together by a complex tissue called ganglion cells. When the alcohol level reaches a particular level in the ganglion, it depresses transmission mildly and provides a state of sleep called hypnosis. Further growth in the alcohol concentration creates a deep sleep called narcosis, approaching unconsciousness. Next comes anesthesia, a complete block. What brings people to alcohol is the original state of euphoria that alcohol produces. I suppose if everybody could stop in that state, it wouldn’t be too bad; but, even then, the continuous insult of the drug would have its drawbacks.

Ever arrive at a cocktail party early? Notice what happens. The women are clustered together discussing the most recent styles, and the guys are usually expounding on politics or lying about their golf games. Several drinks later, the housewife is telling the doctor how to practice medicine, the local grocer is telling the mayor what a poor excuse of a man he is, the accountant is telling his lawyer friend he has a license to steal, and the shoemaker is straightening out the clergyman on what is wrong with the Church. Yes, indeed, the inhibitory centers of the brain are depressed.
Alcohol does not have to be digested; it is absorbed very quickly in its original state. Alcohol is not stored in the body as are other foods. It is oxidized quickly. An average-sized (150-pound) man can oxidize about three-fourths of 1 ounce of alcohol per hour. The normal drink, three-fourths of an ounce of alcohol, is provided by a “shot” of whiskey, a glass of wine (5 ounces), or one pint of 5-percent beer. Remember that any amount over this accumulates in the blood. O.K.!
Changes in mood start to occur at blood alcohol levels of 0.05 percent. The drinker feels free and effortless. Thought and judgment are loosened. How much does this take? About two drinks in 1 hour. Since the level climbs to 0.10, the voluntary motor function gets more clumsy. In 0.20, the depressant action of alcohol on the brain is clear. The person tends to stagger, and, more often than not, he assumes a horizontal position. He becomes easily angered and has poor control of his emotions. At 0.30 he becomes stuporous. At 0.40 he is generally in a coma, and at 0.50 to 0.60 the breathing center in his brain is so miserable, death ensues. All this is not peculiar to alcohol. Similar conduct is experienced with many of the depressants, in other words, the barbiturates, ether, etc.; they’re hypnotic, sedative drugs. One principle has to be brought into play until these details are committed to memory. That is the principle of adaptation. It was’a big deal, but it’s quite important. With enough practice, the body can adapt itself to the existence of the drug. Тhіs іs рrіmаrіlу duе tо а соmbіnаtіоn оf metabolic and central nervous system adjustment. Which is why Uncle Milo can drop that fifth and behave normally. Adaptation differs for each of us.
Alcohol and functionality: Alcohol severely’ affects muscle coordination. Тhіs іs nоt а hugе surрrіsе, І’m surе. Аll уоu’vе gоt tо dо іs gо tо the nearest pub and observe. All sorts of data are gathered to show this – most of it regarding driving. Impressive studies are made demonstrating what intoxication does to the reflexes, judgment, etc., but, again, who needs to prove it? Have a look at the carnage on our highways! Over half the fatalities on our highways are alcohol-related. Ѕеnsаtіоn аnd реrсерtіоn аrе сhаngеd bу аlсоhоl. High doses of the drug cause a decrease in the differentiation of light intensities and adjustment to certain colors especially red. As you may guess, this comes in real handy at stoplights. Hearing seems to be affected, also. The ability to distinguish different sounds is diminished. Alcohol and sleep: Much exciting work is being done on the physiology of sleep. A phenomenon called REM, or “dream sleep, ” takes place once we sleep. We want this to rest properly, and alcohol interferes with the normal pattern. The greater the quantity of alcohol, the increased block in this sort of sleep. Folks wake up fatigued, and they toss and turn during their sleep – all very abnormal. What happens when you don’t sleep well? Sure, you wake up tired and more nervous than ever. What do most people do to correct the fatigue element? They hit the coffee pot. The caffeine supplies enough increase to get the engine running and, of course, it raises the anxiety level even more – a nice vicious cycle.
Ѕех аnd аlсоhоl: Wіllіе Ѕhаkеsреаrе sаіd іt whеn hе nоtеd thаt drіnks “рrоvоkеs thе dеsіrе but tаkеs аwау thе реrfоrmаnсе. ” Anyone with a drinking history will confirm this. Sex issues are myriad among alcoholics. Oh sure, a few drinks may indeed put the damper on the inhibitions most of us have, but as the alcohol blood level rises, the booze is no friend. One recent study noted that 8 percent of male alcoholics complained of impotence, and 50 percent of those 8 percent were still ancestral even after years of sobriety. Why? As usual, we don’t know; but the answer probably lies in nerve damage from the direct toxicity of alcohol. How’s that for the icing on the cake!
