| 单词 | leucocytosis |
| 例句 | An increase is very much more frequent, and is known as leucocytosis, though in this term is usually connoted a relative increase in the proportion of the polymorphonuclear neutrophile leucocytes. Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 1 "Bisharin" to "Bohea" Three cases out of thirty-five, in which high fever and leucocytosis appeared episodically, are hardly enough to justify the view that stupors are the result of a specific infection. Benign Stupors A Study of a New Manic-Depressive Reaction Type The occurrence of physiological and inflammatory leucocytosis is exclusively to be explained by chemiotaxis. Histology of the Blood Normal and Pathological There is a higher leucocytosis in the blood in meningitis than in cerebral abscess. Manual of Surgery Volume Second: Extremities—Head—Neck.

Sixth Edition. These three cases, then, had marked febrile reactions and leucocytosis. Benign Stupors A Study of a New Manic-Depressive Reaction Type To the Müller-Rieder hypothesis, and the chemiotactic theory of eosinophil leucocytosis a third has lately been added, which may be shortly called the hypothesis of the local origin of the eosinophil cells. Histology of the Blood Normal and Pathological To increase the local leucocytosis and so check the spread of infection, a Bier's constricting bandage may be applied. Manual of Surgery Volume Second: Extremities—Head—Neck. Sixth Edition. Here all mononuclear forms gradually ripen to the polynuclear contractile cells, which obey each chemiotactic stimulus by emigration, and which thus bring about sudden leucocytosis. Histology of the Blood Normal and Pathological The occurrence of leucocytosis in any of these conditions is to be looked upon as an indication that a mixed infection has taken place, and that some suppurative process is present. Manual of Surgery Volume First: General Surgery. Sixth Edition. The possibility of the three high temperatures with leucocytosis being due to intercurrent infections must be considered. Benign Stupors A Study of a New Manic-Depressive Reaction Type By this hypothesis we can easily understand eosinophil leucocytosis, the presence of eosinophil cells in exudations and secretions, and the local accumulation of this kind of cell. Histology of the Blood Normal and Pathological Thus in rabbit's blood in which he had experimentally produced leucocytosis, Hankin found a distinct progressive decrease of the pseudoeosinophil granules on allowing the samples of blood to remain some time in the thermostat. Histology of the Blood Normal and Pathological The problem of leucocytosis is one of the most keenly debated questions of modern medicine. Histology of the Blood Normal and Pathological The absence of leucocytosis in some cases of virulent septic poisoning has already been referred to. Manual of Surgery Volume First: General Surgery. Sixth Edition. At the same time she had for two weeks a temperature which often reached 100� or a little above, a weak, irregular but not rapid pulse, a leucocytosis of 17,500 and 80% hemoglobin. Benign Stupors A Study of a New Manic-Depressive Reaction Type In morbid conditions, where substances attracting the mast cells were present, it might be possible to find a suppuration of mast cells, or a mast cell leucocytosis as well. Histology of the Blood Normal and Pathological An explanation of the almost constant increase of the leucocytes of the blood in bacterial diseases is given by the chemiotactic as well as by the phagocytic theory of leucocytosis. Histology of the Blood Normal and Pathological After this came the phase of increase of the white blood corpuscles; and here too exclusively of the polynuclear cells; the polynuclear leucocytosis. Histology of the Blood Normal and Pathological The absence of leucocytosis in a disease in which it is usually present is therefore to be looked upon as a grave omen, particularly when the general symptoms are severe. Manual of Surgery Volume First: General Surgery. Sixth Edition. Upon the clinical importance of leucocytosis, particularly for the infectious diseases and their various stages, an enormous mass of observations has accumulated. Histology of the Blood Normal and Pathological We have entered more fully into the leukopenia experimentally produced by Löwit, in the chapter on leucocytosis. Histology of the Blood Normal and Pathological The morphological character of leucocytosis is certainly not simple, and we must sharply separate various groups, according to the kind of leucocyte increased. Histology of the Blood Normal and Pathological Virchow, the discoverer of leucocytosis, advocated the view, that it resulted from an increased stimulation of the lymph glands.

Sixth Edition. This standpoint had to be abandoned, when Ehrlich shewed that it is chiefly the emigration of the polynuclear neutrophil cells, which brings about leucocytosis. Histology of the Blood Normal and Pathological Virchow indeed, the discoverer of leucocytosis, interpreted it as an increase of the lymphocytes; whereas it is chiefly produced by the polynuclear cells. Histology of the Blood Normal and Pathological It has however been conclusively demonstrated that occasionally in polynuclear leucocytosis, the absolute number of the lymphocytes may decrease. Histology of the Blood Normal and Pathological The eosinophil cells are as a rule diminished in ordinary polynuclear leucocytosis, as Ehrlich had already mentioned in his first communication. Histology of the Blood Normal and Pathological Immediately before and after delivery, particularly in primiparæ, there is usually a moderate degree of leucocytosis. Manual of Surgery Volume First: General Surgery. Sixth Edition. A few diseases shew, besides the neutrophil leucocytosis, an increase of the eosinophils as well, as we shall describe in detail in the next section. Histology of the Blood Normal and Pathological This is borne out by the exceptionally exhaustive hæmatological literature, and particularly by that of leucocytosis. Histology of the Blood Normal and Pathological We distinguish: A. physiological leucocytosis, which appears in health as an expression of changes in the physiological state. Histology of the Blood Normal and Pathological The majority of febrile infectious diseases, pneumonia, erysipelas, diphtheria, septic conditions of the most varied ætiology, parotitis, acute articular rheumatism, etc. are accompanied by a leucocytosis of greater or less extent. Histology of the Blood Normal and Pathological The significance of general leucocytosis has already been referred to. Manual of Surgery Volume First: General Surgery. Sixth Edition. For the details we have quoted, and for the course and variations of leucocytosis in infectious diseases we refer to the thorough monograph of Türk. Histology of the Blood Normal and Pathological These have already proved that a leucocytosis occurs after some considerable time. Histology of the Blood Normal and Pathological Stiénon, who has likewise devoted special researches to the occurrence of leucocytosis in infectious diseases, shews this point very well in his curves. Histology of the Blood Normal and Pathological Toxic leucocytosis occurring in intoxications with the so-called blood poisons. Histology of the Blood Normal and Pathological In exceptionally acute septic conditions the extreme virulence of the toxins may prevent the leucocytes reacting, and leucocytosis may be absent. Manual of Surgery Volume First: General Surgery. Sixth Edition. At the height of ordinary leucocytosis, the number of eosinophil cells is diminished often to disappearance; whilst during its decline they occur in abnormally high numbers. Histology of the Blood Normal and Pathological According to the results of Rieder the proportion of the lymphocytes to polynuclears is practically normal in the leucocytosis of digestion, indeed the lymphocytes are rather in excess. Histology of the Blood Normal and Pathological The explanation of the individual clinical forms of leucocytosis is self-evident from the above description. Histology of the Blood Normal and Pathological Our knowledge of eosinophil leucocytosis is still of comparatively recent date. Histology of the Blood Normal and Pathological Increased elevation of temperature, with or without a rigor, progressive leucocytosis, and sweating, mark the transition between inflammation and suppuration. Manual of Surgery Volume First: General Surgery. Sixth Edition. In the post-febrile period, however, abnormally high values for the eosinophil cells are often found, or even a well-marked eosinophil leucocytosis, which generally attains but moderate degree. Histology of the Blood Normal and Pathological The leucocytosis of digestion consequently differs essentially from the other kinds, in which the neutrophil elements are chiefly increased. Histology of the Blood Normal and Pathological The eosinophilia observed as the result of tuberculin injections, we include, in agreement with Zappert, in the group of post-febrile leucocytosis. Histology of the Blood Normal and Pathological On the origin of polynuclear eosinophil leucocytosis authors have put forward various theories, which we will here critically discuss in succession. Histology of the Blood Normal and Pathological An increasing leucocytosis is evidence that a suppurative process is spreading. Manual of Surgery Volume First: General Surgery. Sixth Edition. For we know from our observations on leucocytosis in infectious diseases that the bacterial stimulating substances act on the eosinophil cells rather in a negative than in a positive sense. Histology of the Blood Normal and Pathological The simultaneous increase of lymphocytes and polynuclears is doubtless brought about by a super-position of a raised income of lymphocytes, and an ordinary leucocytosis caused by the assimilated products of metabolism. Histology of the Blood Normal and Pathological A leucocytosis of mast cells, comparable with the eosinophil or neutrophil forms of leucocytosis, has not been demonstrated in the cases of Canon or other observers. Histology of the Blood Normal and Pathological Thus the intrusion of a leucocytosis, brought about by secondary infection, is able to obliterate more or less the specific character of the blood. Histology of the Blood Normal and Pathological In estimating the clinical importance of a leucocytosis, it is not sufficient merely to count the aggregate number of leucocytes present. Manual of Surgery Volume First: General Surgery. Sixth Edition. Though they have been occasionally found, according to Türk's investigations, in the critical period of pneumonia as parts of a general leucocytosis, the danger of confusion with leukæmic blood changes is non-existent. Histology of the Blood Normal and Pathological Very important conclusions on the interesting question of leucocytosis can be drawn from these observations. Histology of the Blood Normal and Pathological A further, but much less weighty objection to the view that myelogenic leukæmia is an active leucocytosis is, that pus artificially produced in leukæmic patients has nearly always the histological constitution of normal pus. Histology of the Blood Normal and Pathological For if the white blood corpuscles were mechanically carried out of the bone-marrow as a whole, it is incomprehensible that a bacterial infection should alter this process to a polynuclear leucocytosis. Histology of the Blood Normal and Pathological The leucocytosis begins soon after the infection manifests itself—for example, by shivering, rigor, or rise of temperature. Manual of Surgery Volume First: General Surgery. Sixth Edition. In course of time the leucocytes pass through the vessel wall—emigration of leucocytes—and move towards the seat of infection, giving rise to a marked degree of local leucocytosis. Manual of Surgery Volume First: General Surgery. Sixth Edition. It is only on this assumption that the frequently sudden appearance of leucocytosis, as has so often been observed in morbid and experimental conditions, can be satisfactorily explained. Histology of the Blood Normal and Pathological Leucocytosis is present in cases of moderate severity; but in severe cases the virulence of the toxins prevents reaction taking place, and leucocytosis is absent. Manual of Surgery Volume First: General Surgery. Sixth Edition. There is a moderate degree of leucocytosis, but the increase is due not to the polymorpho-nuclear leucocytes but to lymphocytes.
