In a little more than three weeks the wound had completely filled up with healthy granulations, and the dog was sent home to all appearance quite well. At the expiration of three months another tumour made its appearance near the situation of the former one, growing fast; it had attained nearly the size of the other. Mr.
It is their magnificent opaque white granulations which, seen through the transparent skin, form the snow-white stripes in the live Spider. Treated with nitric acid on the microscopic slide, they do not dissolve nor produce effervescence. Uric acid then is not present in this case; and the substance must be guanine, an alkaloid known to be the urinary product of the Spiders.
Electrical burns are treated on the same lines as ordinary burns, by thorough purification and the application of dry dressings, with a view to avoiding the onset of moist gangrene. After granulations have formed, skin-grafting is of value in hastening healing. #Lightning-stroke.# In a large proportion of cases lightning-stroke proves instantly fatal.
Abrasions and superficial wounds usually heal under a scab. The scab is formed by the blood and wound secretions. This protects the surface of the wound until finally the destroyed tissue is replaced by the granulations, and the skin surface is restored. Abnormal granulation is not an uncommon form of healing in domestic animals.
It is sometimes found necessary to employ moist or oily substances, such as boracic poultices, eucalyptus ointment, or balsam of Peru, to facilitate the separation of sloughs, or to promote the growth of granulations. In patients who are not extremely debilitated the slough may be excised, the raw surface scraped, and then painted with iodine.
This simple experiment illustrates the important fact that granulations have no inherent tendency to form pus, but do so only when subjected to preternatural stimulus. Further, it shows that the mere contact of a foreign body does not of itself stimulate granulations to suppurate; whereas the presence of decomposing organic matter does.
In confirmation of these ideas it may be observed, that all the parts of the body endeavour to grow, or to make additional parts to themselves throughout our lives; but are restrained by the parts immediately containing them; thus, if the skin be taken away, the fleshy parts beneath soon shoot out new granulations, called by the vulgar proud flesh.
Before applying the grafts it is usual to scrape away the granulations until the young fibrous tissue underneath is exposed, but, if the granulations are healthy and can be rendered aseptic, the grafts may be placed on them directly.
#Clinical Examination of an Ulcer.# In examining any ulcer, we observe Its base or floor, noting the presence or absence of granulations, their disposition, size, colour, vascularity, and whether they are depressed or elevated in relation to the surrounding parts. The discharge as to quantity, consistence, colour, composition, and odour.
The base of the ulcer becomes red and angry-looking, the granulations disappear, and a copious discharge of thin yellow pus, mixed with blood, escapes. Sloughs of granulation tissue or of connective tissue may form. The edges become red, ragged, and everted, and the ulcer increases in size by spreading into the inflamed and œdematous surrounding tissues. Such ulcers are frequently multiple.
