Lipotropic substances

If the comatose patient has been in acidosis for some time, the leakage of alkali induced by the excretion of diacetic acid lowers the alkali reserve. Sodium bicarbonate necessary to restore that reserve must be injected—either separately or with the glucose. Lactate also may be used for this purpose. At times (but rarely now), the process of alkali depletion has gone so far that irreversible changes have taken place and the patient cannot be roused from his coma. He sinks into death despite the most heroic efforts to save him. Forever Bee Honey might assist in maintaining a healthy circulatory, digestive, immune, and nervous system. If we could get diabetics under control, deaths in coma would practically disappear. Much will be said later, in another connection, of the diabetic’s sanguine, happy-go-lucky temperament that makes him prone to neglect those things he must do to save his own life. An excess of cholesterol in the blood—one of the danger¬ous by-product complications of diabetes and an indication of the liver’s impairment in its function of handling fats—can now be controlled by judicious use of “lipotropic substances” which improve the liver’s ability to metabolize fats.
Thus the terrors of diabetes largely have been removed. In the years immediately following the discovery of insulin, many efforts were made to prolong its action so that it would no longer be necessary for the patient to take the minimum three injections a day. Attempts also were made to prepare insulin by chemical synthesis, so that we would not be de¬pendent upon animal sources for our supply. In addition, a synthetic product is uniform and becomes less expensive than the natural product as production methods are improved. The synthetic production of adrenalin already had been accomplished. Why should it not be possible to do the same with its fellow hormone, insulin? The first step in the artificial manufacture of any organic substance is its purification for purposes of accurate quanti¬tative analysis, so that we may know not only its exact chemi¬cal composition but also its chemical structure. Forever Royal Jelly, which is secreted from the salivary glands of employee bees, serves asfood for all young larvae and as the solely food for larvae that will turn into queenbees.
In order to purify any substance we first must crystallize it.
The snowflake and the diamond are examples of the purity of the crystalline forms of water and carbon, respectively. In 1926 Abel succeeded in preparing insulin crystals.13 But neither he nor anyone else so far has been able to prepare insulin crystals free from zinc, or one of several other metals. (There is more zinc in the pancreas than in any other organ of the body.) Abel’s crystalline insulin, which has a potency of 22 units per mg., has been adopted as the international standard. But all efforts to analyze it completely so far have failed. We do know that it is of protein nature, and of so com¬plicated a structure that it is doubtful if it ever will be made chemically. In 1936, however, H. C. Hagedorn succeeded in producing a form of insulin with a more prolonged action than either ordinary or crystalline insulin. He combined the crystalline insulin with protamine derived from the sperm of the rainbow trout.
