I already see several flaws with the claims this researcher is making. First of all I have never seen any evidence that HCl enters the bloodstream. The only place it is formed in the body is in the stomach to help with digestion and to prevent pathogens from infecting us through the stomach. Same reason drinking alkaline waters, calcium lime, and sodium bicarbonate are really dangerous activities. The acid is neutralized when it leaves the stomach, so it never has the chance to enter the blood or lymphatic system.
Secondly, he claims that this is the acid that activates the white blood cells. Again this is wrong. White blood cells are activated by several substances. One is hydrogen peroxide formed from the enzyme superoxide dismutase (SOD). The only acid that I am aware of that activates white blood cells is ascorbic acid (vitamin C). In fact there is a very simple explanation why sucrose (table sugar) suppresses white blood cells. Insulin is required to not only move sugars out of the blood, but it also transports ascorbic acid in to the white blood cells. When we eat a lot of Sugar the available insulin is used up keeping it busy getting the sugars out of the blood. This leaves very little insulin availability to carry ascorbic acid to the white blood cells for activation. Therefore high Sugar intake suppresses white blood cell activity and therefore results in immune suppression.
Then he claims that lactic acid, fatty acids, carbonic acid, uric acid are decomposition products. This really is not true. These are actually all beneficial acids to the body. And are produced by building, not decomposition. Lactic acid for example is produced by the flora to kill pathogens. It has also been shown that one form of lactic acid has antitumor properties. Fatty acids are needed to form cell membranes, myelin and brain tissue. They can also control Candida albicans. Carbonic acid is essential for maintaining proper vascular constriction so we maintain blood flow to the brain. Without it we would stroke out and die. Uric acid is formed from toxic ammonia. The ammonia is bound to carbon dioxide, which also forms carbonic acid, forming uric acid. Uric acid is an excellent antioxidant and antiseptic. The excess is hydrolyzed in to urea and eliminated.
On the other hand though highly toxic and alkaline ammonia is a byproduct of decomposition.
He is right though that alkalosis (highly alkaline) can be dangerous, even deadly.
The study you linked did not look very promising. From the link:
"Nine cases survived more than 3 years, and 2 cases for more than 4 years."
Even mainstream medicine requires a five year survival to be considered a cure, and cancers still often come back after 5 years after the treatments are finished.
"We have called attention to the fact that the use of the acid intravenously was followed by a considerable increase in the leucocyte count"
An increase in the number of white blood cells is not increasing activity, just cell numbers. Lymphoma is an increase in white blood cells, this does not mean it is a good thing. What it appears to be doing is to act as an antigen. Basically acting as an irritant causing the body to respond as if it had an infection. Even they discuss a potential problem in their next statement:
"A patient who had been suffering from myelogenous leukemia, with a leucocyte count of 84,000 (the normal count being 6,500) was inadvertently given several venous injections of this preparation, with the result that the already high count rose to the unbelievable figure of over 400,000. Obviously, it is poor medical judgment to give a remedy that can only aggravate an existing condition."
I really have to agree with their point. A lot of the problem with blood cancers is that the excess numbers of cells can lead to suppression of organ functions. That is why these cancers are so dangerous to begin with.
Another concern they point out:
"Another important--vitally important--consideration affecting the administration of hydrochloric acid is one which depends upon accurate and painstaking investigation of the individual by the practitioner. Since this measure has the effect of stimulating the defense mechanisms of the blood, it is plain that the sudden increase of "phagocytes" at the focus of infection will be followed by the formation of pus, which, after all, is but an effort on the part of nature to attack invading bacteria. Should this sudden increase of the defense forces take place in an area where the drainage is poor, an abscess may result. For instance, a patient may have a diseased appendix which has been quiescent; there has developed in that patient a balance between the defense elements and the infecting oganisms. A sudden marshaling of the phagocytes at this point may stir the sleeping dog into a first-class battle, with the result that the patient will require immediate operation. Similar situations may develop in other parts of the body, particularly in closed spaces such as the middle ear and sinuses, and the patient must be watched closely for the development of acute symptoms that might require surgical treatment."
You first link does back up a lot of what I have been saying about the dangers of neutralizing stomach acid. This is why taking alkaline waters, calcium lime, or sodium bicarbonate is a really dangerous idea. If neutralizing stomach acid was such as good idea we would all be running out to buy Tums and Pepcid. But I beleive that the majority of people here are smart enough to know that these would be bad ideas as we need stomach acid to prevent pathogen infections from the digestive system, nutrient absorption, and proper protein breakdown. They discuss some of this in your first link:
"The above quotation of Dr. Rowntree is worthy of more than a cursory reading. Many people, both young and old, have, if not a sore or ulcer at the pyloric orifice, an inflamed or congested area indicated by digestive distress. Dr. Moore says that achlorhydria (lack of stomach acid) occurs in some cases of apparently healthy persons and in many cases of gastro-intestinal disease. He also stresses its frequency in diabetes mellitus, and still greater frequency in thyrotoxicosis, as well as in certain non-megalocytic hypochromic anemias. Although achlorhydria occurs in both forms in anemia, a deficiency in hydrochloric acid in the gastric juice is a common symptom in depressive neuroses. It is frequently associated with mental fatigue, persistent worry and strain, especially in persons with a congenitally unstable psyche. The symptoms are very vague: lack of appetite, fullness after eating, gaseous eructations and diarrhea is more common than constipation. Pain is absent. Again we find quoted: "Moreover, hydrochloric acid forms with the duodenal membrane a hormone named secretin, which stimulates the pancreas (to form insulin), also formation of bile and activity of gall-bladder. It is estimated that 2 grams of HCl is required for a meal."
If we have followed the above carefully we shall realize how failure to secrete sufficient HCl in gastric juice gives rise to a long train of events: improper digestion, fermentation, therefore poor absorption of food and mineral elements, a likelihood of sore ulcers or cancer forming at the pyloric outlet; next an inactive liver and pancreas, failure to secrete the secretin hormone --which reduces Sugar in blood, failure to oxidize lactic acid in tissues, more or less retention of CO2 in blood, inability to destroy bacteria sufficiently in food."
