BACKGROUND: Laminin, which is present in all basement membrane, is a multifunctional glycoprotein with diverse biological activities. Like fibronectin, it can influence cell adhesion, growth, morphology, differentiation, and migration as well as the assembly of the extracellular matrix. Laminin primarily affects cells of epithelial origin, and response varies depending on the cells. OBJECTIVE: Studies about the relationship of laminin and the pathogenesis or metastasis of squamous cell carcinoma(SCC). MEHTODS: In this study, we have examined the laminin B1 mRNA expression and localizing pattern of laminin in SCC, using Northern and slot-blot hybridization, in situ hybridization and immunoperoxidase stain. RESULTS: In Northern blot hybridization, 5.6Kb mRNA transcript was detected in control and SCC specimens. Slot-blot hybridization indicated theat amounts of laminin B1 mRNA expression in SCC was 677.0+/-268.5 densitometer absorbance unit, in control was 228.0+/-16.37 unit respectively. There is a 3-fold increase in SCC compared to control. In in situ hybridization, 35S-labeled laminin B1 cDNA-mRNA hybrid granules were detected along the basement membrane and adjacent cells of SCC. In immunoperoxidase stain, laminin has stained strongly and continuously along the basement membrane of the tumor nest in well differentiated SCC, and weakly and interrupted in poorly differentiated SCC. CONCLUSION: These results suggested that laminin might be related to the pathogenesisand metastasis of squamous cell carcinomas.

A 19-month old male patient developed mutiple, firm, plum-colored, finger tip to chestnut sized nodules on the left cheek, right preauricular area, both elbow joints, and right wrist. On physical examination, a right cervical lymph node was palpable. Histology from one of the nodules revealed a diffuse infiltration of atypical, hyperchromatic, polymorphous lymphocytes in the dermis and subrutaneous fat. Bone marow aspiration, chest X-ray, ultrasonogram, and computerized tomogram were performed revealing bone marrow and lymph node involvement. The patient was treated with a POG @8617 schedule. Skin lesions markedly improved after one cycle regimen. We present a case of diffuse, ponrly differentiated, malignant lymphocytic lymphoma in the early childhood.

Transforming growth factor beta(TGF-p), initially identified in vlatelet extracts by virtue of its ability to confer anchorage of independent growth and a necplastic phenotype on mesenchymal cells, has subsequently been identified as a potent inh bit or of proliferation in most cells of epithelial origin. The family of TGF-p peptides is currenly onsisted of four subtypes (TGF-pl, p2, p3, p4). Tkiey are initially translated very larged are urssors of approximately 390 amino acids and produced by a wide variety of cell type. iricluding normal cells and tumor cells. TGF-ps promote deposition of extracellular matrix compcineits, facilitate remodeling events during embryonic development, and suppress immune ce 1 fimetion during the inflammatory process. Several nutaneous diseases are characterized typxcessive and progressive fibrosis of the dermis anil subcutaneous tissues. Prominent amon these disorders are progressive systemic sclerosi(PSS) and generalized morphea(GM), is well as the recently described syndrome of diffuse fasciitis eosinophilia(DF), also known; Shulmans syndrome. The hallmark of the pathologic alteration in these disorders is the excessive deposition of collagen and other connenctive iissues. Macromoleculse in the aerriis and/or the subcutaneous and fascial strutures often accompanied by variable degress of hronic inflammatory cell infiltrates. Now we have examined the expression of TGF-b1 mRNA using of northern blot hybridization with specific sequenced cDNA probe in the normal curltured fibroblasts, placental tissues, and fibrosarcorna derived tumor cell line(HT1080). We found that the size of TGF-b mRNA of each specimen was 2.5kb and theres no alteration of its quality.

Many conditions may weaken bone and predispose to insufficiency fractures, including corticosteroids, radiation therapy, and rheumatoid arthritis, but osteoporosis is the main risk factor. Sacral insufficiency fractures (SIF) that usually present as nonspecific pelvic pain or low back pain are often overlooked in the elderly women with osteoporosis who have sustained minimal or no trauma. Diagnosis of SIF is difficult since the onset is mild, and usually discomfort is attributed to degenerative lumbar spine disease, spinal stenosis, vertebral compression fracture, or neoplasm. So a high index of clinical suspicion of SIF is required to avoid unnecessary diagnostic procedures. In most patients with SIF, bed rest, non-weight bearing ambulation, symptomatic treatment, and therapy for osteoporosis resulted in rapid improvement, and long-term follow-up of this fractures shows usually benign outcome. We are reporting a case of delayed detection of sacral fractures in osteoporotic woman.

Wilson's disease is an inborn error of copper metabolism which may be associated with hepatic cirrhosis and progressive degeneration of the central nervous system. The most common ophthalmologic finding in Wilson's disease is the Kayser-Fleischer ring. Other much less common physical signs include neurologic signs, endocrinologic abnormality. The Kayser-Fleischer ring occurs in the corneal periphery and is usually yellow- brown color. The Kayser-Fleischer ring.copper deposition at the level of the posteior position of Descemet's membran. The authours have recently experienced two cases of wilson's disease. One case. a 20-year-old girl, has Kayser-Fleischer rings in both eyes, amenorrhea, chronic active hepatitis and the other case, a 21-years-old girl, has dense yellow-green colored Kayser-Fleischer rings in both eyes, palilalia, and family relationship. Both cases have been treated with D-penicillaine and low copper diet. After treatment, clinical manifestation have been improved markedly at former case and the other cae is steady stage, but the Kayse-Fleischer rings have not disappeared yet in both cases.

The ginkgo nuts are commonly eaten because of its nutritive value. It also taken as an herbal medicine for its antitussive and expectorant properties throughout Korea, Japan, and China. A range of symptoms of ginkgo nut intoxication including vomiting, abdominal pain, irritability, headaches, and seizures have been reported. It can be fetal in severe cases if emergency care was not available. It was discovered that the toxicity of ginkgo nuts was due to 4-O-methoxypyridoxine. The convulsion can be prevented by administration of anticonvulsants and pyridoxal phosphate. We report a 6-year-old male, without any past or family histories of epilepsy, who presented with generalized tonic clonic seizures. About 7 hours before the seizure, he had consumed approximately 40 roasted ginkgo nuts. He exhibited vomiting and abdominal pain 5 hours after ingestion. After treatment with diazepam and pyridoxal phosphate, his symptoms were resolved and electroencephalogram was normalized. We report on the patient and emphasize pediatricians and parents who have children should be recognizing that neurotoxicity of ginkgo nuts, particularity convulsion inducing effect, can occur occasionally.

BACKGROUND: Epidermolysis bullosa is a group of inherited disorcier characterized by blistering of the skin as a result of minor trauma. OBJECTIVE: There exist very little epidemiologic data for most of the major and minor subsets of inherited epidermolysis bullosa in Korea. We look forward to obtaining basic data for the pathogenesis and treatment of epidermolysis bullosa. METHOD: We performed 1st and 2nd trial of survey with the help of 28 dermatologic Departments snd 28 pediatric departments of medical colleges and 14 dermatologic dipartments of general hospitals. RESULTS: 68 cases were collected and classified by disease type, sex distribution, age distribution, and regional distribution. In disease type, 42 cases of EB simplex(62%), 8 cases of junctional type(12%), 10 cases of dominant dystrophic type(15%), 8 cases of recessive dytrcphic type(12%) were reported. In most cases males predominnted, but in dominant dystrophic type both sexes were equivalent. EB simplex, junctional type, RDEB were mostly developed in the 1st decade of life, dominant dystrophic type in the 2nd decade of life. In regional distribution, the number of pi tients was outstanding in large cities such as Seoul, Pusan, Taegu, Kwanju. CONCLUSION: Due to many limitations and shortage of techniques, this epidemiologic study may be notgood enough for the total estimated number of epidermolysis bullos. patients, prevalence rate, and therapeutic modalities. Furthe evaluation should be necessary next time.

Neurofibromatosis type 1 (NF1) is a relatively common inherited disorder characterized by the formation of neurofibromas, pigmentary abnormalities of the skin, Lisch nodules of the iris, and skeletal abnormalities. Multiple cutaneous neurofibromas are benign nerve sheath tumors and the main manifestation of NF1. Cardiac neurofibroma associated with NF1 is very rare, and few cases have been reported in the literature. Herein, we present the CT and MRI findings of a surgically confirmed left ventricular neurofibroma in a 32-year-old female with NF1.
