Theoretically lime should not be given when there is a tendency to calcification, or when a patient is past middle age. Lime seems to be essential to youth, and to the welfare of nervous patients. Cardiac Emergency Drugs.
It is quite likely, however, that this sort of deposit is only a piece of the general calcification of tissue in arteriosclerosis and old age, and could not be caused by the administration of calcium to a younger patient, and might then occur in older patients even if substances containing much calcium were kept out of the dict.
We began to pick our way down the heaped debris and out upon the plain. For all that day and part of another we searched for an opening out of the Pit. Everywhere was the incredible calcification. The surfaces that had been the smooth metallic carapaces with the tiny eyes deep within them, crumbled beneath the lightest blow.
In course of time, particularly in the larger arteries, this new tissue undergoes degeneration, at first of a fatty nature, but progressing in the direction of calcification, and this is followed by the deposit of lime salts in the young connective tissue and the formation of calcareous plates or rings over a considerable area of the vessel wall.
Constitutional measures, massage, and douching should be employed, and the tendon should be protected from strain. #Calcification and Ossification in Muscles, Tendons, and Fasciæ.# Myositis ossificans.
The muscular system and the bones are commonly also involved, so that rickety changes are often found in these infantile and watery children. In early childhood the processes of calcification and decalcification proceed side by side and with great rapidity, and in health there is always a balance on the side of the constructive process.
Portions of a chondroma, which have undergone calcification or ossification, throw a dark shadow with the X-rays; unaltered cartilage and myxomatous tissue appear as clear areas. [Illustration: FIG.
Occasionally a small thrombus situated behind a valve in a varicose vein or in the terminal end of a dilated vein for example in a pile undergoes calcification, and is then spoken of as a phlebolith; it gives a shadow with the X-rays.
A definite coherence is an Integration; and examples given of integration are the contraction of the solar nebula, the formation of the earth's crust, the calcification of cartilage, the shortening of the body of crabs, the loss of his tail by man, the mutual dependence of plants and animals, the growth of powerful states, the tendency of human occupations to go to distinct localities, the dropping of terminal inflexions in English grammar, the formation of general concepts by the mind, the use of machinery instead of simple tools, the development of "composition" in the fine arts, etc., etc.
They are considered in greater detail in the chapter dealing with tumours of bone. Minute nodules of cartilage sometimes form in the synovial membrane of joints and lining of tendon sheaths and bursæ: they tend to become detached from the membrane and constitute loose bodies; they also undergo a variable amount of calcification and ossification, so as to be visible in skiagrams.
