Recurrent dislocation of the patella
Although the ratio remains constant is the same chemical composition but both are in reduced quality of the state. With the aging of society. Pat the disease gradually attention has been paid. Orange degenerative disease osteoporosis, mainly in women after menopause and the elderly. Generally believed that bone mass is reduced and the resulting occurrence of lower back pain. Fractures as the main symptoms of a comprehensive station sign. The disease can be divided into three categories, namely osteoporosis after menopause (I type); and the old Ryukyu pine disease of bone (II type). I type a good age for the 5l7 哕, especially g is more common in women (female; M 6; 2) is usually a high rotation type. Characterized by a significant reduction in trabecular bone. Rural Development in the 70 11 type of a woman over the age of slightly more 'female: male 2:1), generally low-spin type, in addition to trabecular bone outside the cortex is also significantly reduced. This article focused on this = types, discusses the causes of degenerative osteoporosis and its risk factors. 1. Factors regulating bone metabolism and bone by a huge rural core processes that osteoclast cells destroyed, calcium phosphate and collagen, free from the surface of mononuclear phagocytes after treatment, the formation of a layer of more dense connective tissue membrane, that osteoid, osteoblasts before this gathering. Osteoblasts secrete bone surface limb of the original,[link widoczny dla zalogowanych], so calcium. Phosphorus being deposited on the collagen, and formation of bone. Guo bone formation into bone cells after a calcified bone buried in, and become bone cells. Another part of the surface covering the bone, called the so-called. Lining cells, in this into the A quiescent. Metabolic process of bone repeated here. Recently, extensive studies of the regulation of bone resorption and formation of such factors. There are hormones. Growth factor. Immune factors. To shake fan, the promotion of bone resorption are parathyroid hormone. 1.25 (0H) ... D thyroid cable, cable prostate, adrenal cortex hormones. Inhibit bone resorption of calcium are array index, estrogen and other growth factors, the promotion of bone resorption are EGF (epidermal growth garden.) PDGF (platelet derived growth factor). CSF (colony stimulating factor), TGF-/ sound (transforming growth factor-I), inhibit bone resorption have 'rOr-pi immune factors, and promote bone absorption l tablets are OAF (osteoclasts activator)} IL-I ( interleukin transcripts -1), THF A / (tumor necrosis sleepy son and a swollen / and), inhibit bone rubbish collected. Article IFHr (interferon r). Also on bone formation and bone cartilage l cells cell = a system of paper, have never heard differentiation induced leaf surface to Department of cells. Promote their differentiation factors induced by BMP (bone morphogenetic factor.) BDGF (bone growth factor) and so on. In addition CDGF (hide sub-cartilage growth). Also contributed to the cartilage cell differentiation induction. Through such a complex structure on the regulation of bone formation and absorption is not isolated from each other, but each other. Recently clarified that there are osteoblasts to promote bone resorption hormone (vr ~ a.PGs1.25 (0H) D ·, EGF.TGF, etc.) of the receptor. The claim is likely to be adopted Che osteoblasts. Some information will be passed to the osteoclasts, so that activation of osteoclasts. Speculate the messengers, on the grounds of osteoblast collagenase secreted by the decomposition of the peptide,[link widoczny dla zalogowanych], or bone cells in BGP. On the other hand, it could be damaged bone osteoclast session, bone matrix compartment of the 'I ~ GF to be activated, thereby inserted into bone cells. 2. Degenerative bone disease Ryukyu pine and risk factors of the causes of the above procedure normal bone metabolism and regulation, so that the bone resorption and bone formation can be adequately maintained. And osteoporosis, is due to persistent imbalance between the two, resulting in a decrease in bone mass. The reason to the physiological aging of bone, based on proper way of its risk factors or physical factors in mass,[link widoczny dla zalogowanych], amenorrhea. Che Sok various metabolic abnormalities. Malnutrition, health and other improper insertion. (1) bone mass in older men in the 3O ~ 4o years after reaching its peak. Decrease with age, after menopause women of hyperthyroidism after a metabolic cycle. Will also increase with age, more bone mass reduction in bone due to reduction in the aging process, bone metabolism generally tend to decrease. (2) genetic Ha physical factors; the incidence of this disease was kind of different,[link widoczny dla zalogowanych], generally by blacks. White, yellow sequence, and gradually increased. Japan, U.S. white women compared with women. Ministry of the fourth lumbar spine and femur bone salt content and the relationship between age, Americans often than the Japanese high density of bone salt. Tip of the disease and genetic factors. (3) amenorrhea; female hormones to inhibit bone resorption, more recently, the existence of female bone cells should be ready shake receptor. Estrogen may also promote the formation of the role upheld. Therefore, lack of rest i the United States has been widely used for the treatment of osteoporosis grapes. Women after the menopause to 2 groups. A pass through with the female hormone pier, and the other cast and comfort Jing. . Metacarpal bone were measured after 10-year surplus of salt,[link widoczny dla zalogowanych], the results of an on remaining group reduced bone mass. The cast and the group showed estrogen to prevent bone was set Tsui
