BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.

Elastofibroma is a rare entity of slowly-growing, solid, ill-defined fibroblastic mass occurring almost exclusively in elderly persons and arising mainly from the connective tissue between the lower portion of the scapula and the chest wall. This entity has been considered to be a degenerative pseudo-neoplastic process caused by mechanical friction. We report an additional case of elastofibroma removed from the subscapular region of a 58-year-old woman. Microscopically the tumor was made up of a mixture of swollen eosinophilic collagen and elastic fibers occasionally associated with fibroblasts and mature fat cells. The elastic fibers showed a degenerated beaded appearance or were fragmented into small globules or droplets in a linear pattern.

8.The Relation between the Hyponatremia and the Amount of Irrigation Fluid during Transurethral Resection of Prostate.

We know that irrigating fluid used during transurethral resection of prostate (TURP) is rapidly absorbed through open prostatic venous channels in large amount. The TURP syndrome is symptom complex of hypervolemia & hyponatremia (below 130 mEq/1) due to absorption of irrigating fluid. We studied the change of serum sodium, potassium and symptom of hypervolemia during the perioperative period, in 35 patients undergoning TURP. The aim of this clinical study was to examine the possible relation between the irrigating fluid absorption & the development of hyponatremia after TURP. The results were as follow. 1) Though p value was not acceptable, there waa numerical correlation between the weight of resected prostate and the amount of irrigating fluid. 2) TURP syndrome and severe sodium change were not reported in our studiea, 3) We through the cause of above results that operation time & minimal use of irrigating fluid & minimal bleeding due to advanced operative technique, adequate fluid therapy, and intenaive monitoring of vital sign & physiologic change of patients.

The latissimus dorsi muscle or musculocutaneous flap is one of the most useful flaps in reconstructive surgery. This flap has many advantages, such as its reliable anatomy, long pedicle with large caliber vessels, minimal functional deficit of the donor site, and low incidence of donor site complications. However, the bulkiness of the flap has been considered a disadvantage, so various modifications of technique have been devised. The cutaneous portion of the flap can be safely elevated based on the cutaneous perforating branch of the thoracodorsal vessel. From March 1997 to February 1998, 10 patients underwent reconstructive procedures with thoracodorsal perforator-based free flaps. The composition of the flaps varied in accordance with the nature of the defect. The variances in the flaps were as follows; 3 were cutaneous, 6 musculocutaneous, and 1 osteomusculocutaneous including the rib. All flaps survived with good contour. We concluded that this thin and reliable flap was useful for reconstruction of various defects, and that the composition of the flap, such as subcutaneous, muscle and bone, gave it considerable flexibility as needed.

For the reconstruction of various tissue defects, free tissue transfer has been a very popular method in recent years. A large thin flap is required for aesthetic and functional resurfacing of the extremity defects. As a result, anterolateral thigh free flap has been thought to be useful in reconstructing soft tissue defects requiring thin flap coverage of extremities. The anterolateral thigh flap is a septocutaneous flap based on the septocutaneous or musculocutaneous perforators of the lateral femoral circumflex system. It supplies a large area of skin on the anterolateral aspect of the thigh. The advantages of this flap are safe elevation, a long vascular pedicle, and large caliber vessel. The donor scar is inconspicuous and it could also be used in a sensated flap. From September 1996 to December 1997, 16 cases of soft tissue defect on extremities were resurfaced with anterolateral thigh free flap and the outcomes were satisfactory. This flap is considered useful in one-stage reconstruction of large soft tissue defects of extremities.
