Abstract:
Various markers of bone turnover are already under clinical use in Japan, and mostly for clinical investigation in some countries. Standard values including ranges and variations are summarized in the previous edition of the guideline. The information of additional new markers adapted by government is summarized including clinical features in the new edition 2012. Among the new markers, the methods for measurement for TRACP-5b and ucOC are developed in Japan. As P1NP and TRACP-5b levels are not affected by meals, biological variations are smaller compared with other markers. ucOC is unique because it is to evaluate vitamin K insufficiency for bone. New bone markers adapted in the Japanese guideline 2012 will facilitate clinicians to utilize of metabolic markers of bone for osteoporosis treatment.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
