Page 442 - Sahli15 mentions that in intestinal tuberculosis tubercle bacilli are found in the feces and are therefore of diagnostic importance. "The stools may, however, contain these bacilli even though there is no intestinal tuberculosis (if the patients swallow their sputum). Searching the stools has even been recommended for the diagnosis of lung tuberculosis in cases of irresponsible persons who swallow the sputum. Previous treatment with dilute potassium hydroxide or digestive enzymes is often successful...
Page 443 - ... sputum. Previous treatment with dilute potassium hydroxide or digestive enzymes is often successful and may be serviceable in the examination of mucopurulent particles of the movement which have been isolated from the mass of feces. We do not know whether under certain conditions decomposition will destroy tubercle bacilli in the intestine. At any rate, we cannot always demonstrate tubercle bacilli in the stools, even when there is undoubted intestinal tuberculosis. Perhaps this is on account...
Page 7 - Dr. Sahli's great work, upon its publication in German, was immediately recognized as the most important work in its field. Not only are all methods of examination for the purpose of diagnosis exhaustively considered, but the explanation of clinical phenomena is given and discussed from physiologic as well as pathologic points of view. In the chemical examination methods are described so exactly that it is possible for the clinician to work according to these directions.
Page 443 - Tubercle bacilli are most readily found in the purulent or bloody pieces of diarrheal stools. As tubercle bacilli in the feces may be due to swallowed sputum, we can diagnosticate intestinal tuberculosis if bacilli are found in the feces only when at the same time attacks of diarrhea occur with pus and blood in the stool. The tubercle bacillus must be carefully distinguished from the smegma bacillus, which is said to occur at the anal orifice and might have become mixed with the feces.
Page 686 - Shows the partially diffuse eruption on the mucous membrane of the cheeks and lips ; patches of pale pink interspersed among rose-red patches, the latter showing numerous pale bluish-white spots. FIG. 3. — The appearance of the...
Page 203 - But, in a certain number of cases where the effusion is quite large, if an accurate line be drawn, the flatness will be found to describe a curve, gradually approaching the spine toward the base of the chest, having a space from one to three or more inches broad between the spine and the line of flatness. In this space, resonance will still be detected, and respiration heard.
Page 532 - ... the centrifugal method in general use. In brief, the centrifugal method in general use is as follows : the soil is carefully sampled and a part of the sample which passes through a 2-millimeter sieve is used for analysis. Five grams are usually taken and dried at 110° C. This sample is then shaken with water, to which a few drops of ammonia have been added, for six hours or more. The sample is then placed in tubes and centrifuged until all but the clay particles have subsided ; these, with the...
Page 380 - The molecular weight of oxalic acid is 126.024 and, as the acid is dibasic, a normal solution would contain one-half of the molecular weight; that is, 63.012 grams. For ordinary work the commercial acid may be assumed as sufficiently pure to use as standard. Sixty-three grams of a well-crystallized and chemically pure oxalic acid are dissolved in distilled water and the volume made up to exactly 1 liter. Now, a normal sodium hydroxid solution will require, in order to neutralize a given volume of...
Page 822 - The patient's chin is placed in the curved chin-rest ; the notched end of the upright bar is brought in contact with the face, directly beneath the eye to be examined, which attentively fixes the centre of the semicircle. The other eye should be covered, preferably with a neatly adjusted bandage. The record-chart is inserted at the back of the instrument, and, by means of an ivory vernier, the examiner is enabled to...
Page 720 - A freshly prepared pepsin (HC1 solution) apparently serves as well as the above fluid, but will not keep on standing as the above fluid does. 4. Place the above preparation in the incubator or oven until the clot is digested. A temperature of 37° C. for two or three hours will suffice, but the time is shortened if it is kept at a temperature of 50° C.
