Chilaiditis syndrome is very rare clinical condition that interposed of the hepatic flexure of large bowels between the liver and diaphragm. Clinically it is characterized by abdominal pain that becomes increasingly worse during the day and is often accentuated by deep breathing. On radiologic studies, it shows gas within the hepatic flexure interposed between the liver and diaphragm, which is simulating a pneumoperitoneum. A case was admitted at emergency care center of Yeungnam university hospital and we report it.

Repeated throwing of baseballs by juvenile pitchers is known to cause damages to bone and cartilage as well as soft tissue in the involved upper extremity. Authors present 4 cases of osteochondral lesion at capitellum of the humerus as a result of repeated insult by throwing baseballs in the juvenile pitchers. Pain and limitation of extension of the affected elbow were the commonest symptoms. Cystic change or osteochondral loose body was found on plain X-ray. Treatment consisted of rest and analgesic administration in the patient who has no loose body, while in case of having loose body it was removed surgically without further treatment to the crater. In spite of the rapid relief of the pain by these treatment, limitation of extension persisted for considerable period of time. It is strongly suggested not to overlook elbow pain in young adolescent whose bone is still growing and who can hardly withstand repeated insult to prevent the development of baseball elbow.

The results of cementless total knee arthroplasty(TKA) have improved steadly during the past decade due to development of design, fixation and surgical technique. We analyzed the results of 45 total knee arthroplasties performed with Anatomic Modular Knee(AMK) prosthesis at the department of Orthopedic Surgery, Yonsei University College of Medicine between June 1989 and December 1991 and compared their results of rheumatoid arthritis(RA) and osteoarthritis(OA) patients. The follow up ranged from 2 years to 4 years and 2 months (average 2 years and 8 months). Using the Hospital for Special Surgery(H.S.S.) rating system and Knee Society(K.S.) clinical rating system, we found that the clinical results were similar for RA group(Average; H.S.S. 86.1, K.S. 81.2/74.4) and OA group(Average; H.S.S. 88, K.S. 87.8/77.1) even though the preoperative knee score was lower in RA group(Average;H.S.S.42.8) than OA group(Average;H.S.S. 57.7). The average age of RA patients was 14 years younger than that of OA patients. The improvement of range of motin and preoperative flexion contracture after TKA was remarkable in RA group. The radiologic evaluation based on Knee Society roentgenographic evaluation system revealed proper alignment of all component and no definite radiologic loosening except 1 case in which postoperative deep infection had occurred. On the basis of this prospective clinical and radiologic review, we concluded that uncemented implantation of AMK prosthsis both in RA and OA patients was encouraging.

It was well known that atrial myocytes systhesize atrial natriuretic peptide[ANP], and secrete it into the atrial lumen through the atrial endocardium. But the mechanism for regulation of ANP secretion has not been clearly elucidated, because there was little information of the atrial morphology concerning basal lamina. Basal lamina is surmised as one of barriers that control the movement of ANP, a large molecule. This study was attempted to elucidate the morphological characteristics of basal lamina and connective tissue fibers of atrial endocardial layer by scanning electron microscopy. Basal lamina was exposed by removal of the overlying endothelium. This was achieved by using OsO4 maceration, immersion in aqueous boric acid or EDTA treatment. After removal of the endothelial cell, the specimens were exposed to ultrasonic vibration in case of need. The external surface of basal lamina showed a fairly smooth appearance on the whole, although a few irregular folds are often encountered. Fenestrations, 0.1-1 micrometer in diameter, were randomly observed on the basal lamina, and they were circular to oval in shape. Margin of fenestrations was somewhat distinct and some was divided into two parts by linear structures. The structural differences of fenestrations between right and left atria were not found. The fibroreticular lamina under the basal lamina was revealed by removal of the endothelial cells and their basal lamina. This layer was consisted of interwoven fine fibers. These fine fibers were repeatedly divided and fused, forming reticular network. Some fine fibers connected with basal lamina. Some connective tissue fibers below fibroreticular layer were collected into thick bundles running parallel to myocytes. Above results may serve as a basis for the physiological and morphological studies of atrium.

BACKGROUND: It has been reported that Cortex mori ( Morus alba L, Sangbaikpi ; CM ), the root bark of mulberry tree, plays a role in inhibiting mast cell activation. Human seminal plasma ( HSP ) modulates immune systems and activates rat peritoneal mast cells ( RPMC ). However, the inhibitory agents of HSP - induced mast cell activation have not been disclosed yet. OBJECTIVE AND METHOD: This study was undertaken to determine the effects of CM on HSP-induced mast cell activation by morphologic and functional methods. Morphological changes of RPMC by HSP alone or CM plus HSP were observed with the inverted light microscope. And the amounts of histamine and calcium were measured by radioisotopic enzymatic histamine and radioisotopic calcium assays. RESULTS: By inverted microscopy, HSP-induced RPMC degranulation occurred in a dose-dependent fashion. After pretreatment of RPMC with CM, there was no HSP-induced degranulation. Degranulation index (DI) of RPMC treated with Hanks balanced salt solution (HBSS), CM or HSP was 7.0+/-4.3, 9.0+/-6.2, 56.5+/-16.9, respectively. After pretreatment of RPMC with CM, HSP-induced DI was 11.0 +/-7.1. These results indicate that CM inhibited HSP-induced degranulation of RPMC. HSP-induced RPMC histamine release (HR) was dose-dependent. HR of RPMC treated with HBSS, CM or HSP was 0.18+/-0.10, 0.30+/-0.19, 4.48+/-0.86 ug/ml, respectively. After pretreatment of RPMC with CM, HSP-induced HR was 0.52+/-0.21 ug/ml. These results indicate that CM inhibited HSP-induced HR from RPMC. Intracellular calcium level ( ICL) of RPMC was also increased according to the concentration of HSP. ICL of RPMC treated with HBSS, CM or HSP was 6.1+/-1.0, 9.0+/-2.1, 30.2+/-6.5 pmole, respectively. After pretreatment of RPMC with CM, HSP-induced ICL of RPMC was 11.6 +/- 3.3 pmole. These results indicate that CM inhibited HSP-induced calcium uptake of RPMC. CONCLUSION: From these results, it is suggested that CM contains some substances which inhi-
