A case of eavernous hemangiomatosis involving alI tendon sheath of flexors and median nerve of the right forearm is reported. This case was a 22 year old Korean male who complained of painful swelling of the flexor side of right wrist region, limited motion of wrist joint, loss of pinching and opposition with tingling sensation on the admission. Roentgenographic examination revealed fusiform swelling of the soft tissues in flexor aspect of the right wrist region, with phlebolith, 3mm. in diameter. The tumor mass looked like strawberry in shape, and was scattered into all tendon sheath of flexors of the forearm, median nerve, the distal half of pronator quadrtus and other surrounding soft tissues. The specimen was confirmed as cavernous hemangioma in microscopic examination. The right long arm splint was applied for 3 weeks, and then the patient was treated with physical therapy for 4 months. Pinching, opposition, and motion of the right wrist joint recovered almost completly, and no evidence of the recurrence of hemangiomatosis was seen until 8 months after surgery.

Chicken calvarial bone is known to contain various cell types, but their exact composition is unknown. By characterizing the chicken calvarial bone biochemically, it can be used to study biochemical, histochemical actions of bone cells in general. Calvaria of I8-day-old white leg horn embryo was aseptically dissected and bone cell populations were isolated by sequential enzymatic digestion. Histochemical study for osteoclast-like bone cell population was performed with tartrate resistant acid phosphatase(TRAP) stain and for osteoblast-like bone cell population, alkaline phosphatase(ALP) stain was performed. Biochemical study for osteoblast-like bone cell population was performed using alkaline phosphatasetal.P) assay. Following conclusions were obtained from this study. 1. TRAP positive multi and mononuclear cells were mostly observed in group I and II, indicating that osteoclast-like bone cell population is mostly found in these groups. 2. All the cultured groups showed almost equal ALP activities and were positive for ALP stain, indicating that osteoblast-like bone cell population is evenly dispersed in all culture groups. 3. Experimental group treated with I,25(OH)2D3 showed increase in ALP activity in contrast to the control group, confirming previous studies that I,25(OH)2D3 increases ALP activities in vitro bone cultures. 4. Results from von Kassa's stain indicated that in vitro bone formation had occured after 3 weeks of culture with beta glycero phosphate.

Due to the great deal of effort that has gone into the study of osteoclastic differentiation and activation over the last few decades, the mechanisms of these two events have been discovered gradually. Nitric oxide(NO-), which is produced from arginine by a nitric oxide synthase, opened up a new area of biological research. Recently, it has been reported that NO- is produced by osteoblasts stimulated by lipopolysaccharide and several other cytokines. In this study, the effect of sodium nitroprusside(SNP), a donor of nitric oxide(NO-), on osteoclast-like cell formation and on mature osteoclast function was examined. To determine the mechanism of the inhibitory effects of SNP decreased not only the basal 45Ca release but also thee bone resorption induced by PTH and l,25-dihydroxyvitamin D3 (I ,25[OH]2D3). The inhibitory effect of SNP on bone resorption induced by PTH appeared 2 days after treatment, whereas SNP effect on inhibiting bone resorption induced by l,25[OH]2D3 appeared at the third days. When chicken and rat osteoclasts were cultured on dentin slices, treatment of 300micronM SNP resulted in a significant decrease in dentin resorption by osteoclasts in terms of total resorption area and average individual area. We also examined the effect of SNP on formation of osteoclast-like cells that is TRAP-positive multinucleated cells from chicken and rat bone marrow cells in the presence or absence of 10(-8)M l,25[OH]2D3. The addition of 300 micronM SNP inhibited the formation of TRAP-positive multinucleated cells. The present data suggest that SNP, possibly as a NO- donor, inhibits the osteoclastic differentiation and osteoclastic activity.

Intracerebral hemorrhage is the most serious complication of cerebral arteriovenous malformations (AVM). To identify angiographic characteristics of AVM which correlate with a history of hemorrhage, we retrospectively analyzed angiographic findings of 25 patients with AVM. Nine characteristics were evaluated; these include nidus size, location, arterial aneurysm, intranidal aneurysm, angiomatous change, venous drainage pattern, venous stenosis, delayed drainage and venous ectasia. These characteristics were correlated with hemorrhage, which was seen in 18 (72%) patients of CT or MR images. Venous stenosis (P<.05) and delaved venous drainage (P<.05) well correlated with a history of hemorrhage. Arterial aneurysm and intranidal aneurysm also had a tendency hemorrhage although they did not prove to be statistically significant. Detailed analysis of angiographic finding of AVM is important for recognition of characteristics which are related to hemorrhage and may contribute to establishing a prognosis and treatment planning.

Pulmonic autograft replacement of the aortic valve (Ross procedure) has been to have potential for growth in children, no complication of antiocagulation, and enhanced durability. Therefore, Ross operation is indicated in the young, in patients with an active life style, and when anticoagulation is contraindicated. However, late autograft valve has occurrd more frequently in patients with significant size discrepancy between the pulmonay valve annulus and the aortic valve annulus. In order to resolve this problem, we performed aortic annuloplasty with Duran ring for more accurate and strong reinforcement. We report a case using the Duran ring as a method of aortic annuloplasty during Ross procedure.
