The Tyranny of the Dark During digestion, the phagocytes prowl into the intestine, and ingest and devour bacteria, that might otherwise give rise to disease. Text Book of Biology, Part 1: Vertebrata A macrophage is an irregularly shaped phagocyte that is amoeboid in nature and is the most versatile of the phagocytes in the body.

Evening Round Up More Good Stuff Like Pep Through connective tissues wander the phagocytes, cells that are difficult to distinguish, if really distinct, from the white blood corpuscles. Text Book of Biology, Part 1: Vertebrata I think they stimulate the wrong kind of phagocytes. Our Elizabeth A Humour Novel Special and remarkable properties—chemical activities of an extraordinary character—have been gradually developed in the floating phagocytes and in similar non-floating fixed cells over which the blood flows. More Science From an Easy Chair Larger bodies, such as needles or bullets, which are not capable of being destroyed by the phagocytes, become encapsulated. Manual of Surgery Volume First: General Surgery. Sixth Edition. The other is the phagocytes or white corpuscles, the free lances of our corporeal militia, which attack and kill the invading bacteria. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries Dead cells exert a similar attraction for the large phagocytes. Disease and Its Causes You sink brutishly into an armchair, warm your legs at the fire, and let the leucocytes and phagocytes fight it out. Shandygaff The phagocytes swallow them greedily and make an end of the invasion. More Science From an Easy Chair Minute bodies that are not capable of being absorbed, such as particles of carbon, or of pigment used in tattooing, are taken up by the phagocytes, and in course of time removed. Manual of Surgery Volume First: General Surgery. Sixth Edition. Therefore the antiseptic he is seeking is one that will assist the serum in protecting and repairing the broken tissues and will kill the hostile bacteria without killing the friendly phagocytes. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries I wish more of their own phagocytes would begin to preach non-resistance and try to teach great moral lessons to invading germs. The Wrong Twin There was no argon, no radium, no phagocytes—at least to my knowledge, and aluminium was a dear, infrequent metal. Tono Bungay These latter agents, actual particles of the living animal in which they exist, are the "eater-cells," or "phagocytes"—minute, viscid, actively moving cells, resembling the animalcules called "amœba." More Science From an Easy Chair The lymph contains the opsonins which act on the bacteria and render them less able to resist the attack of the phagocytes, as well as the various protective antibodies which neutralise the toxins. Manual of Surgery Volume First: General Surgery. Sixth Edition. When they migrate from the blood vessels in great numbers they finally, after having fulfilled their office as phagocytes, degenerate into the corpuscular elements of pus, which is the creamy liquid contained in an abscess. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents He replied cryptically that he was an out-and-out phagocyte, and getting more so every time he read a newspaper. The Wrong Twin Well, I heard this theory that the phagocytes eat up the disease germs years ago: long before you came into fashion. The Doctor's Dilemma Our need for a relish with oysters is the same thing as the need of the phagocyte for a relish with its microbes, not something "poetically" compared to it. More Science From an Easy Chair These are known as opsonins or alexins, and they act on the bacteria by a process comparable to narcotisation, and render them an easy prey for the phagocytes. Manual of Surgery Volume First: General Surgery. Sixth Edition. But as a general thing the phagocytes do not succeed in making away with all the pathogenic germs, or even with enough of them to prevent the illness which they tend to produce. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents They don't say, like that poor old maunderer I read this morning, that there's no use preparing—that a million phagocytes will spring to arms overnight if their country's invaded. The Wrong Twin Nature has provided, in the white corpuscles as you call them—in the phagocytes as we call them—a natural means of devouring and destroying all disease germs. The Doctor's Dilemma This idea gave rise to the theory of phagocytosis, and the corpuscles were consequently named phagocytes. The Story of Germ Life On account of their activity as germ destroyers, these cells have been called germ killers or ~phagocytes~. Nature Cure There are also a smaller number of white corpuscles, that are known as phagocytes, whose mission is to destroy micro-organisms that are prejudicial to life. The Royal Road to Health Watch our phagocytes come forward now, just as those tiny white corpuscles rush through the blood to an invaded spot. The Wrong Twin We shall begin stimulating the phagocytes on—on—probably on Tuesday next; but I will let you know. The Doctor's Dilemma The battle between these phagocytes and the bacteria goes on vigorously. The Story of Germ Life The phagocytes absorb morbid matter, poisons or microorganisms by enveloping them with their own bodies. Nature Cure The phagocytes are stimulated; they devour the disease; and the patient recovers—unless, of course, he's too far gone. The Doctor's Dilemma There is at bottom only one genuinely scientific treatment for all diseases, and that is to stimulate the phagocytes. The Doctor's Dilemma It stimulated the phagocytes; and the phagocytes did the rest. The Doctor's Dilemma In other cases the bacteria prove too strong for the phagocytes. The Story of Germ Life What we call pus is made up of the bodies of live and dead phagocytes, disease taints and germs, blood serum, broken-down tissues and cells, in short, the debris of the battlefield. Nature Cure To me you are simply a field of battle in which an invading army of tubercle bacilli struggles with a patriotic force of phagocytes. The Doctor's Dilemma If in the end the phagocytes prove too strong for the invaders, the bacteria are gradually all destroyed, and the attack is repelled. The Story of Germ Life The phagocytes wont eat the microbes unless the microbes are nicely buttered for them. The Doctor's Dilemma They multiply too rapidly, and sometimes they produce secretions which actually drive the phagocytes away. The Story of Germ Life It has also been found that the phagocyte and tissue cells in the neighborhood of the area of irritation produce antipoisons or natural antitoxins, which neutralize the bacterial poisons and kill the microorganisms of disease. Nature Cure These resistant forces are in part associated with the productions of body poisons, and are in part associated with the active powers of special cells which have been called phagocytes. The Story of Germ Life The origin of the poisons and the exact method of action of the phagocytes we may well leave to the future to explain. The Story of Germ Life Having made a promise to your wife, which my principles will not allow me to break, to stimulate those phagocytes, I will stimulate them. The Doctor's Dilemma It is equally dependent upon whether he has the bodily vigour to produce alexines in proper quantity, or to summon the phagocytes in sufficient abundance and vigour to ward off the attack. The Story of Germ Life It involves the destruction of phagocytes, bacteria, blood vessels, and tissues just as a battle between contending human armies results in loss of life and property. Nature Cure It is based at the foundation, doubtless, upon the powers of the body cells, either the phagocytes or other active cells. The Story of Germ Life |
