Purpose:
To investigate the effects of recombinant human growth hormone(rh-GH )on mandibular bone loss with or without teeth in the ovariectomized rats.
Methods:
Three-month aged ovariectomized rats were utilized as postmenopausal osteoporosis models and all the molars in left mandibles were extracted. After operations, the rats began to receive rh-GH 1 mg.kg(-1).d(-1) with subcutaneous injection for ten days. Weight of the rats ,mineral density of the mandibular bone and 3 other parameters were measured at 8th week and 12th week. The data was analyzed with F and t test.
Results:
The weight of the rats increased and mandibular bone mineral density of the rats were significantly improved after rh-GH treatment, P<0.05.
Conclusion:
Rh-GH can increase the weight of the old rats and restore mandibular bone mass in mandibles with or without teeth.

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...
