Chronic Lead Exposure
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, numbness and tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases, anemia, seizures, coma, or death may occur. Exposure to lead can occur by contaminated air, water, dust, food, or consumer products. Lead poisoning poses a significantly increased risk to children and pets as they are far more likely to ingest lead indirectly by chewing on toys or other objects that are coated in lead paint. Additionally, children absorb greater quantities of lead from ingested sources than adults. Exposure at work is a common cause of lead poisoning in adults with certain occupations at particular risk. Diagnosis is typically by measuremen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metaphyseal
The metaphysis (: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including Mesenchymal stem cell, mesenchymal stem cells, which give rise to Osteoblast, bone and Adipocyte, fat cells, as well as Hematopoietic stem cell, hematopoietic stem cells which give rise to a variety of Blood cell, blood cells as well as bone-destroying cells called Osteoclast, osteoclasts. Thus the metaphysis contains a highly metabolic set of tissues including Spongy bone, trabecular (spongy) bone, Blood vessel, blood vessels, as well as Marrow adipose tissue, marrow adipose tissue (MAT). The metaphysis may be divided anatomically into three components based on tissue content: a cartilaginous component (epiphyseal plate), a bony component (metaphysis) and a Fibrous jo ...
