| neovascularization, pathologic | Proliferation of blood vessels in tissue not normally containing them, or proliferation of blood vessels of a different kind than usual in tissue. It includes angiogenesis in tumour growth, diabetic retinopathy, haemangiomas, arthritis, and psoriasis. (12 Dec 1998) |
|---|
| retinal neovascularization | <ophthalmology> New blood vessels originating from the retinal veins and extending along the inner (vitreal) surface of the retina. This process is characterised by a diseased retina with a disturbed vascular bed. Neovascularization is associated with a variety of conditions including vascular occlusion, sickle cell diseases, sarcoidosis. (12 Dec 1998) |
|---|---|
| corneal neovascularization | New blood vessels originating from the corneal veins and extending from the limbus into the adjacent corneal stroma. These vessels may lie in the superficial and/or deep corneal stroma. Neovascularization is a sequel to numerous inflammatory diseases of the ocular anterior segment, including trachoma, viral interstitial keratitis, microbial keratoconjunctivitis, and the immune response elicited by corneal transplantation. (12 Dec 1998) |
| neovascularization | Proliferation of blood vessels in tissue not normally containing them, or proliferation of blood vessels of a different kind than usual in tissue. (05 Mar 2000) |
| neovascularization, physiologic | The development of new blood vessels, especially in tissues where circulation has been impaired by trauma or disease; in healthy tissue transplants to restore circulation between a transplant and surrounding tissue; and across anastomotic sites. (12 Dec 1998) |
| bone demineralization, pathologic | Decrease, loss, or removal of the mineral constituents of bones. Temporary loss of bone mineral content is especially associated with space flight, weightlessness, and extended immobilization. Osteoporosis is permanent, includes reduction of total bone mass, and is associated with increased rate of fractures. Calcification, physiologic is the process of bone remineralizing. (12 Dec 1998) |
| pathologic | 1. Indicative of or caused by a morbid condition. 2. Pertaining to pathology (branch of medicine that treats the essential nature of the disease, especially the structural and functional changes in tissues and organs of the body caused by the disease). (18 Nov 1997) |
| pathologic absorption | Parenteral absorption of any excremental or pathologic material into the bloodstream, e.g., pus, urine, bile, etc. (05 Mar 2000) |
| pathologic amenorrhoea | Amenorrhoea due to organic disease, either uterine or other, e.g., ovarian or pituitary failure, Simmonds' disease, inconstant and irrelevant debility. (05 Mar 2000) |
| pathologic amputation | Amputation necessitated by cancer or other disease of the limb and not by an injury. (05 Mar 2000) |
| pathologic calcification | Calcification occurring in excretory or secretory passages as calculi, and in tissues other than bone and teeth. (05 Mar 2000) |
| pathologic diagnosis | A diagnosis, sometimes postmortem, made from an anatomic and/or histologic study of the lesions present. (05 Mar 2000) |
| pathologic fracture | A fracture occurring at a site weakened by preexisting disease, especially neoplasm or necrosis, of the bone. (05 Mar 2000) |
| pathologic glycosuria | Chronic excretion of relatively large amounts of sugar in the urine. (05 Mar 2000) |
| pathologic histology | <study> This is the science concerned with the study of microscopic changes in diseased tissues. (09 Oct 1997) |
| pathologic physiology | That part of the science of disease concerned with disordered function, as distinguished from anatomical lesions. Synonym: physiopathology. (05 Mar 2000) |
