The pulmonary sequestration is rare congenital anomaly characterized by the presence of a part of lung tissuewhich is supplied by an aberrant systemic artery from the aorta or its branch and usually has no communicationwith the normal bronchial tree. The authors present 3 cases of intralobar pulmonary sequestration, studied by CTand /or US. Typical CT features of intralobar pulmonary sequestration are homogenous or unhomogeneous, relativelylow density lung mass near the diaphragm, having feeding artery from the aorta or branching vessels within themass during bolus injection or dynamic CT.

Authors concluded an experimental study in order to find out what the effects of parathyroid hormone on cells derived from human Trabecular bone in vitro are on terms of proliferation of cells, adenylate cyclase activity and production of small substances such as osteocalcin and collagen type I. The results were as follows; 1. 3H-thymidine incorporation into cultured osteoblast was initially low (day 1–2), increased by exponential curve from day 3 till day 11. The uptakes of 3H-thymidine by osteoblasts, when bovine parathyroid hormone was added, increased dose-dependently. Greater increments were seen at concentrations of bovine PTH higher than 5.0 X10-8 mole. 2. Intracellular c-AMP accumulation was stimulated by bovine PTH in a dose-dependent manner and greater production was seen at concentrations of bovine PHT higher than 5.0 X10-8 mole. Maximal stimulation was observed at 1 X10-7 mole of bovine PTH. The concentrations of c-AMP were observed significantly higher in the presence of bovine PTH in a dose-dependent manner when compared to those of bovine PTH-absent culture condition. 3. Treatment with bovine parathyroid hormone of cultured osteoblasts resulted in increase of alkaline phophatase activity and synthesis of osteocalcin in the cultured media in a dose-dependent manner. Greater productions were observed at concentrations of bovine PTH higher than 5.0 X10-8 mole. 4. Synthesis of type I collagen by cultured osteoblasts in bovine PTH-added media was inversely proportional to their concentration, whereas control group showed minimal increments of no significance. These in vitro findings may suggest that PTH has a stimulatory effect on proliferation of osteoblast, c-AMP production and alkaline phosphatase activity in a direct manner.

We report a case of focal eosinophilic myositis of the frontalis muscle in a 38-year-old man. The skin lesion was a single firm flesh-colored swollen lesion measuring 1×1.5 cm in size on the right forehead. The biopsy revealed inflammatory infiltrates composed of mainly eosinophils and a few lymphocytes in the muscles. The skin lesion subsided with intralesional injections of triamcinolone acetonide, 5 mg/ml.

Intraventricular cysticercosis is the rest form of cerebral cysticercosis and almost all are within the fourthand third ventricles. Authors have experienced a case of pathologically proven giant intraventricular cysticercalcyst involving the lateral ventricle, studied by conventional CT and metrizamide CT, and report with brief reviewof literature.

Spondylometaphyseal dysplasia (SMD) is an extremely rare, which affects the spine and metaphy-ses of the tubular bones on terms of enchondrogenesis. Children who had Kozlowski dwarfism, type of SMD are not recognized until they reach school age since they have normal clinical feature, weight and size in early childhood. Authors experienced a typical case of Kozlowski type of SMD in a 10 years old male who had i) generalized platyspondyly with anterior tapering of vertebrae ii) generalized metaphyseal dysplasia iii) minimal changes in the carpal and tarsal bones. This case is to be reported with review of references.

Parathyroid hormone (PTH) has not been studied as extensively as therapeutic agents of osteoporosis, but the anabolic effect of parathyroid hormone on the skeleton has been demonstrated in several studies. The current study was undertaken to assess the effect of parathyroid hormone on bone mass and its biomechanical competence using ovariectomized rat model. Fifty female Sprague Dawley rats of 3 months old were randomized into five groups, 10 in number for each groups. Group I: sham-operation, Group II: ovariectomy (OVX) plus saline injection, Group III: OVX plus PTH 20ug/kg, Group IV: OVX plus PTH 40ug/kg, Group V: OVX plus PTH 80ug/kg. Treatment regimens were initiated 8 weeks after ovariectomy and continued for 4 weeks thereafter. Bone mineral density was measured in proximal one-third level of tibia by dual energy X-ray absorptiometry (QDR-2000, Hologic, U.S.A). Biomechanical competence was assessed in lumbar vertebral body by universal testing machine (Instron-4467, U.S.A). The average of bone mineral density in sham operated group was 0.088+/-0.0084g/cm (2), and in control group (OVX +/- saline)was 0.065+/-0.0095g/cm (2). Bone mineral density decreased in control group significantly. The average of bone mineral densities in Group III, IV, V (OVX + PTH) were 0.071+/- 0.0089, 0.081+/-0.0086 and 0.084+/-0.0093g/cm (2), respectively. This showed that parathyroid hormone injected groups had significantly higher bone mass than control group (p<0.0#5), and the increment was in proportion to the amount of parathyroid hormone in the range (p<0.05). The average of biomechanical competence of lumbar vertebral body in sham operated group was 30.036.24 MPa and was 25.11+/-5.69 MPa in control group. In Group III, IV,V they were 25.74+/-6.77, 27.96+/-5.17 and 29.83+/-5.79 MPa, respectively. Above results seem supportive of the phenomenon that parathyroid hormone exert anabolic effect on osteoporotic bones in certain experimental condition.
