Page 643 - ... that is not always just, since it ceases to exist in the intimate structure of the organs, in which all the grand vital phenomena take place, and in which also occur all the changes that constitute the morbid state.
Page 642 - ... likewise. On the one hand, inasmuch as the blood nourishes the solids, and as without its presence they cannot support life, the state of the solids cannot but be influenced by the state of the blood. • The chemist might as well say that the nature of a body does not depend on the nature of the elements that compose it. On the other hand, the solids, considered with respect to their relations to the blood, form but two classes : the one contributing to make the blood, such as those concerned...
Page 643 - No one solid, therefore, can undergo the slightest modification without producing some derangement in the nature or quantity of the materials destined to form the blood, or to be separated from it.
Page 368 - A state of active hyperœmia generally precedes the osseous transformation of the fibrous, cartilaginous, and fibro-cartilaginous tissues. M. Rayer observed, that when he excited an artificial irritation in the fibro-cartilage of a rabbit's ear, the part was at first softened ; a yellow matter was next deposited in its texture ; and, finally, a calcareous deposit was formed, and a true ossification produced. M. Cruveilhier likewise observed different portions of periosteum, ligaments, and cartilages,...
Page 671 - ... is the conclusion which we ought to draw, consistent with true logic and sound physiology ? " Certainly this, that here, as in the preceding cases, it appears that the primary cause of the disease should be referred to the blood, which, in this case has altered its nature under the influence of unknown causes, as it has in the others in consequence of the commixture of various foreign substances.
Page 648 - ... containing vessel. When the blood once becomes solid, it displays indubitable symptoms of vitality ; vessels are produced, and secretions formed in it ; and different alterations of nutrition, resembling those observed in the tissues, may also occur. If we examine whence this coagulated blood derives its vitality, we find that it cannot partake of the common life of the rest of the body, since it very often merely touches the surrounding tissues, without being in any manner continuous with them....
Page 655 - Beclard mention* a case in which the heart and principal trunks of the vessels were filled with a solid clot, the interior of which presented numerous collections of encephaloid matter. M. Velpeau found a mass of encephaloid in the midst of a clot of blood contained in the vena cava. He also cites a case of a man that died almost suddenly, after having shewn some symptoms of cerebral congestion, and in whom, upon examination, there was found through the whole extent of the circulatory system, a blood...
Page 107 - Venesections employed in such cases to combat an irritation, which in reality does not exist, invariable produce a marked aggravation of all the symptoms ; on the contrary, it frequently happens that by stimulating the nervous system of these chlorotic patients by the physical and moral emotions of matrimony, we produce a more natural complexion and colour of the whole cutaneous surface, thus indicating a correspondent improvement in the process of sanguification, and in proportion as the...
Page 643 - ... some derangement in the nature or quantity of the materials destined to form the blood, or to be separated from it. Physiology, then, leads us to the conclusion that every alteration of the solids must be succeeded by an alteration of the blood, just as every modification of the blood must be succeeded by a modification of the solids. Viewed in this light...
Page 122 - And there was again war at Gath, where there was a man of great stature, who had six fingers on each hand, and six toes on each foot, twenty-four in number; and he also was descended from the giants.
