Experimentally induced osteoarthrosis in the temporomandibular joint of the mouse

(1) 6-week-old ICR mice were injected daily with pharmacologic doses of triamcinolone diacetate (1.5 mg/kg body weight) for 8 consecutive weeks. (2) The temporomandibular joint served as a model for histological and histochemical examinations concerning the effect of glucocorticoid hormone upon bone and cartilage. (3) Histochemical reactions indicated a large number of lipid droplets within the peripheral vasculature. (4) Histological examinations revealed pathologic features, indicative of primary osteoarthrosis.
