tetracycline and Osteoarthritis--Hip

Patients with POAG have lower corneal endothelial cell density than healthy controls of the same age. This may be attributed to mechanical damage from elevated IOP and toxicity of glaucoma medications.. Mycophenolic acid was detected in all cats. The dose 10 mg/kg given q12h for 1 week was tolerated (n = 3). The efficacy of MMF as an immunosuppressant and long-term safety in cats of this dosage regimen is unknown.. T

Total hip replacement was carried out in 7 patients with advanced osteoarthritis of the hip joint. The patients were given tetracycline orally before operation to label the newly formed bone tissues. The excised femoral heads were processed into undecalcified sections, which were subjected to both fluorescence microscopic and scanning electron microscopic (SEM) observation. Band-shaped golden fluorescence was detected along the trabeculae, reflecting newly formed bone tissues by the cambium layer of the periosteum. In the intertrabecular space, reticular and spherical golden fluorescence was detected, implying newly formed bone tissues by the marrow stromal cells. Under SEM, both reticular and spherical new bone tissues were discovered in the inter-trabecular space as mentioned above. There were two forms of reticular new bone tissues, a diffuse form and a tape-shaped new bone tissues. The diffuse bone tissues grew and expanded and eventually studded the inter-trabecular space. The tape shaped tissues, which were first deposited on the trabecular arch surface, increased in amount and then woven into thin and dense tapes of the reticulum. These tapes contacted in an end-to-end fashion, and appeared to shuttle back and forth through the trabecular arches, forming new secondary arch structures. The spherical new bone tissues were deposited on the surface of the trabecular arch structures and gradually packed the intertrabecular space. These new bone tissues were contributed to hyperplasia in the osteoarthritic femoral head.

The tidemark is a metabolically active zone in the calcified layer of the cartilage in which it is possible to show that there is calcifying activity even over a short period of time using a tetracycline labelling technique. The tidemark slowly advances in the direction of the non-calcified cartilage and analysis of double-tetracycline labelled cartilage shows that this is not an appositional phenomenon like that occurring in bone, but that, where present, several tidemarks can be labelled at the same time. Each tidemark may therefore be metabolically active and it is not just the tidemark adjacent to hyaline cartilage which incorporates calcium.
