Many postmenopausal women have vitamin D and calcium deficiency. Therefore, vitamin D and calcium supplementation is recommended for all patients with osteopenia and osteoporosis. We used an experimental rat model to test the hypothesis that induction of osteoporosis is more efficiently achieved in peripheral bone through combining ovariectomy with a unique(More)
For assessing mechanical properties of osteoporotic bone, biomechanical testing combined with in silico modeling plays a key role. The present study focuses on microscopic mechanical bone properties in a rat model of postmenopausal osteoporosis. Female Sprague–Dawley rats were (1) euthanized without prior interventions, (2) sham-operated, and (3) subjected(More)
Osteoporosis is one of the deleterious side effects of long-term glucocorticoid therapy. Since the condition is particularly aggressive in postmenopausal women who are on steroid therapy, in this study we have attempted to analyse the combined effect of glucocorticoid (dexamethasone) treatment and cessation of oestrogen on rat bone. The dual aim was to(More)
In this study we demonstrated that individual melanotropes expressed differing levels of POMC mRNA. Interspersed among the melanotropes was a small population of process-bearing cells expressing GFAP. We compared cellular resolution and feasibility for quantitation of hybrids formed by oligonucleotide probes labeled with two different markers using in situ(More)
In estrogen-deficient, postmenopausal women, vitamin D and calcium deficiency increase osteoporotic fracture risk. Therefore, a new rat model of combined ovariectomy and multiple-deficient diet was established to mimic human postmenopausal osteoporotic conditions under nutrient deficiency. Sprague-Dawley rats were untreated (control), laparatomized (sham),(More)
The regulation of D2 dopamine receptor binding, immunoreactivity, and mRNA was studied in melanotropes of the intermediate lobe of the rat pituitary. D2 dopamine receptor-binding experiments showed that chronic haloperidol treatment (2 mg/kg for 14 days) significantly increased the Bmax but not Kd of [3H]spiperone binding, whereas bromocriptine treatment (2(More)
