Page 101 - Numerous examinations of morbid urine have convinced me, that in this country, at least, the sediments of oxalate of lime are much rarer than they are represented to be by English writers. These investigations have led me to the following results; when the respiratory process is in any way disturbed, we most frequently observe a copious excretion of oxalate of lime; it is most common either in fully developed pulmonary emphysema, or when the pulmonary tissue has lost much of its elasticity after...
Page 96 - Thus it may easily be understood why, after the use of driuks rich in carbonic acid, of alkaline bicarbonates, or vegetable salts, oxalic acid is increased in the urine ; the superfluous carbonic acid which has entered the blood, or been generated there from the salts of organic acids, must obstruct the absorption of oxygen and the perfect...
Page 168 - ... of more difficult solubility than the magnesian phosphate. This last circumstance explains probably why phosphate of lime falls as a deposit from acid urine, while phosphate of magnesia remains in solution. The particular or special reasons for regarding deposits of phosphate of lime as of more moment than those of the triple phosphate, are derived from direct pathological observation. I have observed that when this deposit occurs, it is very apt to be persistent ; and when it has disappeared,...
Page 101 - The patients are generally much emaciated, excepting in slight cases, extremely nervous, painfully susceptible to external impressions, often hypochondriacal to an extreme degree, and, in very many cases, labour under the impression that they are about to fall victims to consumption. They complain bitterly of incapability of exerting themselves, the slightest exertion bringing on fatigue. Some feverish excitement, with the palms of the hands and soles of the feet dry and parched, especially in the...
Page 11 - This conversion of urea takes place, after a time, in distilled water, even without the aid of the spirit-lamp. " 3rd. The decomposition of urea is effected, either with or without heat, much more readily in fluids which are alkaline, and especially in those the alkalinity of which arises from the presence of lime in any form. " 4th. The conversion of urea is retarded, and sometimes altogether prevented, by an acid condition of the fluid in which it is present ; and this is equally the case whether...
Page 133 - A more extended investigation has led me to the following results. In all cases where the supply of lactates to the blood is very great, — whether this depends on an excess of acid being formed in the muscles, or on the use of a diet tending to produce it, or on an imperfect process of oxidation in the blood, — lactic acid may be detected in the urine with all the certainty which in the present state of chemistry can be expected in such researches.
Page 101 - ... common in some forms of dyspepsia in which the functions of the liver are deranged. They are generally much* emaciated, excepting in slight cases, extremely nervous, and painfully susceptible to external impressions, often hypochondriacal to an extreme degree, and in very many cases labor under the impression that they are about to fall victims to consumption.
Page 101 - The mental faculties ave generally but slightly affected, loss of memory being sometimes more or less present. Well-marked dyspeptic feelings are always complained of. Indeed, in most of the cases in which I have been consulted, I have been generally told that the patient was ailing, losing flesh, health, and spirits, daily ; or remaining persistently ill and weak, without any definite or demonstrable cause.
Page 99 - In the dyspeptic conditions in which Prout and Bird have found sediments of oxalate of lime, I have failed in discovering anything of the sort; on the contrary, I have generally found the sediments in the urine of such patients to be free from these crystals.
Page 96 - The source of this salt must, however, not be sought for only in the pre-formed oxalates, but in the amount of alkalies in combination with vegetable acids present in the food; for, as we have already mentioned, they induce an augmentation of the oxalate of lime. In all the wellmarked cases to which I have alluded, the increase of the oxalate of lime seemed to be combined with disturbance of the respiratory process. Thus it may easily be understood why, after the use of drinks rich in carbonic acid,...
