1.Effect of Repeated Ultraviolet Irradiation on Epidermal Melanocyte of the Expossed and Shielded Ear in C57BL Mice.
Korean Journal of Dermatology 1988;26(3):283-291
In this experiment 40 adult male C57BL mice were used. The one ear of each animal was irradiated with high pressure mercury lamp (Burdick'UV-800) and the other ear was covered with nontransparent tape. Using split epidermal sheets treated with DOPA solution, a quatitiative study of epidermal melanocyte was carried out from the exposed and the shielded ear continuously on every second day during 14 daily exposures to 100 mJ/cm of UVB. The results were as follows : 1. Repeated radiation with ultraviolet light elicited a significant increase in population of melanocytes and the possible mechanism is a direct replication of the functioning melanocytes. 2. UVB irradiation induced increase in the number of epidermal melanocytes in covered ear as well as in irradiated ear. It is suggested that the population increase in the shielded skin is initiated by one or more systemic factors originating from the UVB irradiated skin.

2.A Case of Guttate Morphea with Secondary Cutaneous Mucinosis.
Korean Journal of Dermatology 1997;35(1):165-168
The cutaneous mucinose are a group of connective disorders characterized by the deposition of mucin in the dermis. Thc disease may be a primary (metabolic) or secondary (catabolic). Secondary mucinosis is common in lupus erythematosus and dermatomyositis but rare in morphea. We report a case of guttate morphea with secondary cutaneous mucinosis.

Although epidural fibrosis after laminectomy is considered to be the cause of pain in a number of patients, the exact relationship of postoperative scar tissue and symptoms remains controversial. However it is generally accepted that epidural fibrosis after surgical decompression of neural tissue has to be avoided. To diminish the likelihooa that such a scar will form, fat grafts have been used to create an interpositional membrane. Compression of a nerve after the use of a fat graft is rare; postoperative cauda equina syndrome, resulting from compression by a grafted fat. We report the case of a patient who had this complication.

STUDY DESIGN: The authors retrospectively analysed the difference of clinical natures in contained vs. ruptured HIVD. OBJECTIVE: To compare contained HIVD with ruptured HIVD in respect of clinical symptoms, signs and the result after surgery. SUMMARY OF LITERATURE REVIEW: In contained disc herniation, the disc material remains beneath tile intact outer annulus. But, once disc material penetrates through the limit of posterior annulus, it is a ruptured herniation or disc extrusion/sequestration. There is few report concerning the clinical characteristics related to type of herniation. MATERIALS AND METHODS: Forty-six patients, treated by open discectomy from March 1990 to December 1994, were followed up for minimum two years. The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR, and severity of radiating pain were periodically followed up on the predesigned protocol. Result: Twenty patients had contained disc and remaining 26 had ruptured disc. The mean age of contained disc was 31.4 years and that of ruptured disc was 43.3 years. In preoperative examination, 18/26 cases of patients with ruptured discs, developed pain in less than 3 months, compared with 7/20 cases of does with contained ones. Motor deficit was positive in 25/26 cases (96.2%) of ruptured discs and 12/20 cases (60%) of contained ones. 23/26 cases (80.8%) of patients with ruptured discs, had sensory deficit compared with 12/20 cases (60%) of those with contained ones. There was no significant difference in SLR and DTR change between ruptured and contained disc. CONCLUSIONS: Factors such as age, motor and sensory deficits and duration of symptoms had correlation with the type of herniation, but SLR and DTR change showed no statistical difference in this study. Clinical outcome showed no significant difference between two groups, but in ruptured group, the results were getting worse with the time goes. On the basis of this study, we concluded that the clinical symptoms and signs were different between the two groups, but surgical results showed no statistical difference.

To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.
