174. Effect of Alcoholic Drinks upon the Liver. It is to be noted that
the circulation of the liver is peculiar; that the capillaries of the
hepatic artery unite in the lobule with those of the portal vein, and
thus the blood from both sources is combined; and that the portal vein
brings to the liver the blood from the stomach, the intestines, and the
spleen. From the fact that alcohol absorbed from the stomach enters the
portal vein, and is borne directly to the liver, we would expect to
find this organ suffering the full effects of its presence. And all the
more would this be true, because we have just learned that the liver
acts as a sort of filter to strain from the blood its impurities. So
the liver is especially liable to diseases produced by alcoholics. Post
mortems of those who have died while intoxicated show a larger amount
of alcohol in the liver than in any other organ. Next to the stomach
the liver is an early and late sufferer, and this is especially the
case with hard drinkers, and even more moderate drinkers in hot
climates. Yellow fever occurring in inebriates is always fatal.
The effects produced in the liver are not so much functional as
organic; that is, not merely a disturbed mode of action, but a
destruction of the fabric of the organ itself. From the use of
intoxicants, the liver becomes at first irritated, then inflamed, and
finally seriously diseased. The fine bands, or septa, which serve as
partitions between the hepatic lobules, and so maintain the form and
consistency of the organ, are the special subjects of the inflammation.
Though the liver is at first enlarged, it soon becomes contracted; the
secreting cells are compressed, and are quite unable to perform their
proper work, which indeed is a very important one in the round of the
digestion of food and the purification of the blood. This contraction
of the septa in time gives the whole organ an irregularly puckered
appearance, called from this fact a hob-nail liver or, popularly, gin
liver. The yellowish discoloration, usually from retained or perverted
bile, gives the disease the medical name of cirrhosis.[29] It is
usually accompanied with dropsy in the lower extremities, caused by
obstruction to the return of the circulation from the parts below the
liver. This disease is always fatal.
