We studied the relationship between the bone mass and biochemical parameters in 175 normal premenopausal, 72 normal postmenopausal and osteoporotic postmenopausal women, between 20 and 88 years old, and in 40 patients with hyperthyroidism, and 23 patients with primary hyperparathyroidism, between 13 and 64 years old. The bone mineral density (BMD) of the spine (L2-L4) and proximal femur (femoral neck) was measured by dual-energy X-ray absorptiometry using a QDR-1000, Hologic. The bone mineral content (BMC) of the radius was measured by single photon absorptiometry (SPA) using a model 2780, Norland. Serum PTH, BGP and calcitonin (CT) were determined by radioimmunoassay. The BMD of the spine (L2-L4), and the proximal femur in postmenopausal women were negatively correlated with age. The mean BMD in patients with postmenopausal osteoporosis was significantly lower than that in normal postmenopausal women. In postmenopausal women, age was positively correlated with BGP, PTH, CT and negatively correlated with P. In patients with osteoporosis, the BMD of the spine was negatively correlated with serum BGP. The BMC of radius in patients with hyperthyroidism decreased significantly compared with that in the controls, and was negatively correlated with F-T3. The BMC of the radius in patients with primary hyperparathyroidism was significantly lower than that in the controls, and was negatively correlated with serum BGP and serum calcium. The measurements of biochemical parameters such as serum BGP, ALP and PTH may be useful in the assessment of metabolic bone diseases.  相似文献

Bone mass is purportedly reduced by an excess of endogenous or exogenous thyroid hormone or perhaps by calcitonin deficiency. Patients who have undergone thyroidectomy could be subject to all of these effects. In the present study we tried to demonstrate, whether lack of calcitonin following thyroidectomy has a significant influence on bone density. We measured thyroid hormone levels, TSH and calcitonin and assessed the bone mass in the hip and lumbar spine of 55 patients (32 f, 23 m), who had undergone a subtotal thyroidectomy between 1938 and 1996 on the reason of a non-toxic goitre. TSH levels were suppressed in 16 patients. Serum concentration of total calcium, intact PTH, osteocalcin were normal in all subjects. The mean fasting calcitonin level was in the patient group 2.09 +/- 0.7 pg/ml and in the control group, age matched healthy volunteers, 2.8 +/- 1.2 pg/ml. However, the serum level of calcitonin was not significantly lower than in the control group. 43 patients had an osteopenia or osteoporosis. The interpretation of the results in this study is hampered by the fact, that in women results may be influenced by involutional osteoporosis. Therefore we focus on the potential for osteoporosis among the 23 men. The results of our study indicates, that there is a significant reduction in bone mass in male after thyroidectomy, no matter whether T4 therapy is given or not, and whether TSH is suppressed or in a normal range.  相似文献

Recollection micropuncture and clearance studies were carried out on thyroparathyroidectomized hamsters to clarify the localization of the effects of parathyroid hormone (PTH) on renal electrolyte transport. The clearance data confirmed that PTH inhibits phosphate and enhances calcium and magnesium reabsorption. These effects appeared to result from actions of the hormone in several parts of the nephron. In the proximal tubule PTH did not affect H2O reabsorption but inhibited phosphate reabsorption ((TF/P)PO4 increased from 0.46 +/- 0.04 to 0.57 +/- 0.03, P less than 0.02) and appeared to enhance calcium and magnesium reabsorption ((TF/UF)Ca decreased from 1.41 +/- 0.07 to 1.25 +/- 0.06, P less than 0.001, and (TF/UF)Mg from 1.66 +/- 0.10 to 1.51 +/- 0.08, P less than 0.05; in control animals (TF/UF)Ca increased from 1.51 +/- 0.10 to 1.65 +/- 0.11, P less than 0.01). PTH further inhibited phosphate reabsorption and enhanced calcium and magnesium reabsorption between the late proximal and early distal sites of puncture. Comparison of fractional deliveries of calcium and magnesium from the late distal tubule with their fractional excretions suggests an additional effect beyond the distal puncture site. The phosphaturic, but not the calcium- and magnesium-retaining, effects of PTH were abolished by a 16-h fast.  相似文献

In many patients with involutional osteoporosis anabolic steroids may produce a rapid subjective improvement and a pronounced reduction in the frequency of complaints. Animal experiments have demonstrated that anabolic steroids can also have an objective effect on bone tissue. Twenty (20) post-menopausal osteoporotic patients were randomly assigned to 2 different treatment regimens; 10 patients were treated with 50 mg i.m. of nandrolone decanoate (ND) every 3 wk for 12 mth and 10 patients were treated with a placebo. Both groups also received an oral calcium supplement (1 g/day). Bone mineral content (BMC) was measured by dual photon absorptiometry before and after 1, 3, 6 and 12 mth of treatment. Plasma alkaline phosphatase (ALP) and urinary hydroxyproline excretion were measured at the same time. Intestinal calcium absorption was measured by the 47Ca oral test before and after treatment. A transiliac bone biopsy was performed before and after treatment in 4 patients in each group. After 1 yr there was a significant increase in lumbar spine BMC in the group receiving calcium plus ND. A progressive increase in plasma ALP was also observed in the group treated with ND but this was not significant, whereas radiocalcium absorption did increase significantly in this group. Histomorphometric study of bone samples demonstrated a significant increase in trabecular bone volume (TBV) and in active osteoid surface area in the patients treated with ND. Because plasma ALP tends to increase when a small decrease in bone resorption occurs (as measured by urinary hydroxyproline excretion) and the active osteoid surfaces also significant augment, we concluded that ND therapy increases the bone formation rate through inhibition of bone resorption. This interpretation could explain the considerable increase in lumbar spine BMC and the significant increase in TBV observed in patients treated with ND.  相似文献

Calcium homeostasis was determined from ionized calcium (Ca2+), total calcium (Cat) and bound calcium (Cab) levels, content of calcium-regulating hormones: calcitonin (CT) and parathyroid hormone (PTH). Lipid peroxidation (LPO) intensity was assessed from the blood plasma hydroperoxide level in 71 patients with bronchial asthma and chronic asthmatic bronchitis. The findings evidence that high blood serum levels of Ca2+ and Cab and a tendency to reduction of PTH content are characteristic of nonsevere and medium-severity atopic asthma. In bacterial asthma Ca2+ level increases at the expense of Cab, that is parallelled by elevation of CT content, as the disease progresses in severity. Blood CT level gradually decreases until it disappears completely in Stage III bacterial asthma, whereas PTH level grows. CT/PTH ratio may be an indicator of disturbed equilibrium in the CT-PTH hormonal system. In the course of treatment Ca2+ binding, most manifest in bacterial asthma, increases, CT level grows and PTH one reduces. A tendency to normalization of hormonal levels resultant from therapy does not eventuate in their complete recovery; hormonal levels remain shifted, this pointing to the essential contribution of endocrine mechanisms to calcium homeostasis disorders in asthma.  相似文献

It is well known that regulation of calcium homeostasis in bone remodeling is one of the most crucial factors for maintaining healthy bones. Parathyroid hormone (PTH) is probably the most important hormone that participates in the bone remodeling process. Another important biochemical factor governing bone metabolism is osteocalcin (BGP). Although the physiological functions of both of these factors are well known, there is still very little known regarding their specific genetic determination and in particular, the specific genes that may regulate the circulating concentrations of these substances. In the present study, we examined whether nine single nucleotide polymorphisms (SNPs) in the human homologue of the mouse progressive ankylosis gene (ANKH)-one of the key genetic factors involved in bone mineralization-can be associated with PTH and BGP levels in apparently healthy human populations. The study sample comprised 244 nuclear families (840 individuals). After adjustment of BGP and PTH for the significant covariates (sex, age and BMI), the contribution of the putative genetic effects was statistically significant (P < 0.001) for both biochemical factors: 45.27 +/- 10.8% for PTH and 30.19 +/- 12.6% for BGP. Application of transmission disequilibrium tests (TDTs) revealed a significant association (P < 0.05) between PTH and two SNPs: rs39968 and rs875525. However, the association became particularly significant for four TDTs (P-values ranging from 0.0025 to 0.0008) when the association with the haplotypes generated from the above SNP was tested. This association remained significant even after correction for multiple testing with a false discovery rate of 0.05.  相似文献

Bone turnover was determined in 125 patients with rheumatoid arthritis (RA). Bone Gla protein (BGP) and alkaline phosphatase (AP) were used as markers of bone formation. Fasting urinary calcium relative to creatinine (FU Ca/Cr) and fasting urinary hydroxyproline relative to creatinine (FU Hpr/Cr) were used as markers of bone resorption. These variables were compared to the values of two groups of normal controls in order to elucidate the pathophysiology of the osteopenia occurring in patients with RA. When the patients were divided into groups according to treatment (gold salts, penicillamine, or glucocorticoids), serum AP was highly significantly increased in all three groups, whereas serum BGP was below the normal mean. FU Ca/Cr and FU Hpr/Cr were moderately decreased in the groups treated with gold salts or penicillamine, but increased in the glucocorticoid-treated group. When divided according to sex and menopausal state and glucocorticoid treatment versus non-glucocorticoid treatment, there was a balance between bone formation and bone resorption parameters in all groups, except glucocorticoid-treated men and premenopausal women who had increased values of bone resorption parameters.  相似文献
