BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

The role of the periosteum on osteointegration of Bio-Oss(R)(Geistlich, Wolhusen/Switzerland) was studied in rabbit calvarial defect. 12 New Zealand white male rabbits between 2.8 and 4 kg were included in this randomized, blinded, prospective study. Each rabbit was anesthetized with Ketamine HCl(5 mg/kg) and Xylazine HCl(1.5 ml/kg). An incision was made to the bony cranium and the periosteum was reflected. Using a 6-mm trephine bur(3i. USA), four 8-mm defects were created with copious irrigation. The defects were classified into barrier membrane(Tefgen(R), Lifecore Biomedical, Inc, U.S.A.) only group as a control, Bio-Oss(R) with barrier membrane group, Bio-Oss(R) with periosteum covering group, and Bio-Oss(R) without periosteum covering group. There were 2 rabbits in each group. The wound was closed with resorbable suture materials. Rabbits were sacrificed using phentobarbital(100 mg/kg) intravenously at 1, 2, and 4 weeks after surgery. The samples were fixed in 4% paraformaldehyde, and decalcified in hydrochloric acid decalcifying solution(Fisher Scientific, Tustin, CA) at 4degrees C for 2-4 weeks. It was embedded in paraffin and cut into 6 micrometer thickness. The sections were stained with H & E and observed by optical microscope. The results were as follows; 1. The periosteum played an important role in osteointegration of Bio-Oss(R) in bone defects. 2. When the periosteum remained intact and Bio-Oss(R) was placed on the defect, Bio-Oss(R) with periosteum covering has been incorporated into the newly formed bone from 2-week postoperatively. 3. When the periosteum was removed at the surgical procedure, invasion of connective tissue took place among the granules, and new bone formation was delayed compared to periosteum covering group. Therefore, when the bone grafting was performed with periosteal incision procedure to achieve tension-free suture, the integrity of the overlying periosteum should be maintained to avoid fibrous tissue ingrowth.

To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.

Pheochromocytoma are functioning tumors which arise in chromaffin tissue of adrenal gland. The signs and symptoms of pheothromocytoma results from the release of the highly potent amines, epinephrine and norepinephrine by the tumors. This tumor release both epinephrine and norepinephrine into the blood stream for distribution to distant sites of action. Circulating norepinephrine produces widespread vasoconstriction, causing increased peripheral resistance and resulting in increased systolic, diastolic and mean arterial pressures. The direct effect on the heart is to increase the rate and force of contraction. As important effect is the reduction of plasma volume caused by prolonged increases in circulating norepinephrine and epinephrine. These adrenergic aminess have prominet metabolic as well as hemodynamic effects. The increase oxygen consumption and elevation of blood glucose and lactic acid level caused by epinephrine are much more marked than the increase produced by comparable amounts of norepinephrine. Anesthetic management of pheochromocytoma should considered prevent serious alterations in blood pressure. So, We present the case of anesthetic management for pheochromocytoma which control of hypertensive crises by the use of a intravenous infusion of sodium nitroprusside.
