In some cases a decided absolute increase oflymphocytes occurs.
It must be borne in mind in this connection that lymphocytes are normally more abundant in the blood of children than in that of adults.
Lymphocytes are formed in the lymphoid tissues, including that of the bone-marrow.
Endothelial cells generally predominate in carcinoma, but are accompanied by considerable numbers of lymphocytes and red blood-corpuscles.
The percentage of lymphocytes is usually moderately increased in those conditions which give leukopenia, especially typhoid fever, chlorosis, pernicious anemia, and many debilitated conditions.
In the latter, the lymphocytes sometimes exceed 98 per cent.
Larger forms of lymphocytes are frequently found, especially in the blood of children, and are difficult to distinguish from the large mononuclear leukocytes.
The lymph collected from a lymphatic before it has passed through a lymph gland contains a few leucocytes, and though the number of lymphocytes is greater in the lymph after it has flowed through a gland it is never very great.
Coagulation of the blood is retarded, and there is a marked diminution in the number of leucocytes, especially the neutrophils, and an increase in the lymphocytes (Kocher).
An excess of mono-nuclear lymphocytes and, sometimes, tubercle bacilli may be discovered in the cerebro-spinal fluid withdrawn by lumbar puncture.
The granulation tissue which forms as a result of the reaction of the tissues to the presence of the virus is chiefly composed of lymphocytes and plasma cells, along with an abundant new formation of capillary blood vessels.
The local lesions are to be regarded as being of the nature of reactions against accumulations of the parasite, lymphocytes and plasma cells being the elements chiefly concerned in the reactive process.
The induration is due not only to the dense packing of the connective-tissue spaces with lymphocytes and plasma cells, but also to the formation of new connective-tissue elements.
It is the cells of the excretory organs as well as the lymphocytes which pick up carmine-grains when injected.
Lumbar puncture, February 29, showed a slightly darkened fluid, with approximately normal amount of albumin, one or two lymphocytes and rare red blood cells.
Lumbar puncture showed no lymphocytes or excess of albumin.
Of course, the question whether the lymphocytes and hyperalbuminosis of the fluid might not be syphilitic must be raised.
The spinal fluid was afterward examined and found to be negative to the Wassermann reaction but contained 15 lymphocytes per cubic mm.
The lymphocytes decreased further according to a puncture November 2.
In sundry cases, not only blood but also lymphocytes have been found, sometimes in a hypertensive puncture fluid.
The facts show that each warm-blooded animal seems to possess a specificity whereby its lymphocytes destroy transplanted tissue taken from a foreign species.
The role of lymphocytes in these cases has never been investigated.
Murphy found that by increasing the number of lymphocytes in an animal (which can be accomplished by a mild treatment with X-rays) the immunity against foreign grafts as well as against cancer from the same species can be increased.
On fully grown rats in which the lymphocytes had been destroyed by X-rays (as ascertained by blood counts) tissues of foreign species grew perfectly well.
It was known that by treatment with Roentgen rays the lymphocytes in an animal could be destroyed.
In the normal blood of adults the number of the lymphocytes amounts to about 22-25% of the colourless elements.
Thus lymphatic leukæmia affords a striking proof that the lymphocytes are cells of a peculiar kind, and which are quite independent of the polynuclear cells.
It has however been conclusively demonstrated that occasionally in polynuclear leucocytosis, the absolute number of the lymphocytes may decrease.
The breaking up of ordinary pus cells or lymphocytes does not appear to give rise to any such substances; but there is much evidence that the decomposition products of epithelial and epithelioid cells act chemiotactically.
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.
In quite isolated cases, an increase of the lymphocytes in the blood in consequence of the injection of tuberculin into tuberculous individuals has been seen.
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.
Ehrlich had previously observed that when extensive portions of the lymphatic glandular system are put out of action by new growths and similar causes, the number of the lymphocytes may be considerably diminished.
By the aid of the iodine-eosine method the reaction of the protoplasm of the lymphocytes is shewn to be strongly alkaline.
We define lymphocytosis as an increase of the lymphocytes of the blood; Fränkel like Uskoff regards it as the emigration of the young forms of the white blood corpuscles into the blood.
The lymphocytes are derived from lymphoid tissue, wherever it exists in the different parts of the body.
There may be an increase in the proportions present in the blood of lymphocytes (lymphocytosis), and of eosinophile cells (eosinophilia).
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "lymphocytes" in a variety of sentences. We hope that you will now be able to make sentences using this word.
