A 26-year-old man presented with a bluish speckled patch on the dorsum of the left hand. It had apperaed at birth as a bluish spot. Since adolescence the lesion extended and at the time of visiting hospital it covered the most part of the dorsum of the left hand and even some palmar aspect. The histopathological and ultrastructural examination revealed numerous dermal melanocytes, mainly in the upper dermis. Clinically and pathologically, the patient was diagnosed as having dermal melanocyte hamartoma, a distinct type of dermal melanocytosis.

Dermal wound healing is a complex process that involved inflammation leading to re-epithelialization, granulation tissue, and tissue remodeling. Previous studies from our laboratory have shown that polysaccharides isolated from fungus, Phellinus gilvus (PG) have various anti-inflammatory activities. In present study, we have assessed the effect of polysaccharides from PG on the dermal wound healing of polysaccharides from PG in streptozotocin-induced diabetic rat model. Six of 6-mm circular wounds were created with biopsy punch on the 4th day after induction of diabetes. After 24 hours, each test substance was applied to the wound twice a day for next 5 days. Circular wounds treated with PG showed significantly reduced wound contraction and complete reepithelialization, as compared to wounds of non-treated (p < 0.05). These results show that polysaccharides isolated from PG enhanced wound repair in diabetic impaired healing, and could be developed as a wound healing agent in such clinical settings.

OBJECTIVE: Telomerase is a ribonucleoprotein that synthesizes TTAGGG repeats onto chromosome ends. The expression of telomerase is thought to be required for cellular immortality and carcinogenesis. This study was conducted to examine the telomerase activation occurs in cervical carcinogenesis. METHODS: The standard telomeric repeat amplification protocol(TRAP) was used to examine telomerase activity in tissues of 10 normal cervix, 10 carcinoma in situ, and 21 invasive cervical carcinoma. RESULTS: Telomerase activity was detected in tissues of 16/21(76.2%) invasive carcinoma, in 5/10(50.0%) carcinoma in situ, and in 3/10(30.0%) normal cervix. But the degree of telomerase activity in normal cervix was weak. There was significant difference in 3 groups(p<0.05). The results of neoadjuvant chemotherapy in 10 invasive cervical carcinoma were as follows. In 8 cases of which tumor size decreased more than 50%, 5 were positive for telomerase. In 2 cases that didn't respond to chemotherapy by tumor size, 1 was positive for telomerase. There was no significant difference between 2 groups. All of the 5 cases that had pelvic lymph node metastasis revealed positive telomerase activity, and the 11 cases of 16 cases that didn't have pelvic lymph node metastasis were positive for telomerase, but there was no significant difference in 2 groups. The positivity of telomerase activity in clinical stage of invasive cervical carcinoma was 73.3% in stage I(11/15), 75.0% in stage II(3/4), 100% in stage III(1/1), and 100% in stage IV(1/1), but there was no significant difference in each stages. CONCLUSION: Telomerase seems to be uniquely associated with malignant transformation of cervix and can be used as a tumor marker. Additional studies are needed to better clarify the biological significance of telomerase expression in cervical tumorigenesis.

The mutation of p53 tumor suppressor gene is the most common genetic variation of primary malignant tumors. The occurrence, progression and reaction for medical management of cancers can be different according to the characteristics of p53 gene, even if they are same kinds of malignant tumors. In this study, the property of p53 gene in 4 kinds of squamous cell carcinoma cell lines were investigated by using immunocytochemistry, PCR-SSCP, sequencing and Western blot methods. As a result, p53 mutation detected in 3 kinds of squamous cell carcinoma cell lines. Namely, it is found that T in codon 176 changed to A, and G in codon 281 changed to A in KUMA3 cell lines; CC in codon 241 changed to TT in KUMA4 cell lines; G in codon 266 changed to T in KUMA6 cell lines. In single nucleotide polymorphism of codon 72 of p53 gene, the genetic variations are Arg/Pro heterozygote in KUMA3 and KUMA4 cell lines; Arg/Arg homozygote in KUMA5 cell lines; Pro/Pro homozygote in KUMA6 cell lines. These results will provide useful data for p53 gene researches of various squamous cell carcinomas.

Tanzer reported microtia reconstruction using autogenous costal cartilage, thereafter so many plastic surgeons have tried various modification to get further refinement of reconstructed auricle. But the multiple stages of ear reconstruction required prolonged hospitalization and cost. In order to decrease the number of surgical stages and for the maximal convolution, we have employed a surgical procedure with three layered costal cartilage graft for the high profile auricle, concha formation and lobule transposition at the same time. However, it has still been difficult to reconstruct the tragus in cases of microtia that lack such component. We reconstructed the tragus using part of the microtic ear in addition to our above procedure simultaneously. This procedure is started with transposition of the lower two-thirds of the microtic ear to make lobule and then the upper third of the microtic ear is elevated as a chondrocutanenous flap which is then transposed 120-180degree C downwards to reposition at the area anterior to the conchal cavity. Using this technique, we have reconstructed 28 microtic ears. Adequate positioning of the auricle and tragus have been achieved and a more natural auricle obtained.

We present three cases of eosinophilic pustular folliculitis without eosinophilia in a 19-year-old female, a 27-year-old male, and a 51-year-old male. Multiple erythematous plaques with papules and pustules were observed on the face in two patients and on the face, trunk, and extremities in the third patient. Histopathologic findings showed hair follicles and the sebaceous glands infiltrated with mixed inflammatory cells composed of eosinophils and neutrophils, characteristic of eosinophilic pustular follicultitis. However, peripheral blood eosinophilia was not present in any of our three cases.

In order to investigate the risk factors of ischemic brain stroke (IBS) in diabetic patients, we analyzed 416 cases selected from 6239 diabetic patients admitted to Severance Hospital from Jan. 1983 to Dec 1987. Two hundred and eight cases had IBS. The other 208 cases without IBS were selected as a control group by a stratified random sampling method. The two groups were compared using various clinical characteristics of diabetes mellitus (DM) and known risk factors of IBS. In diabetics with IBS, the duration of DM was longer (9.2 +/- 7.1 years), hypertension was more frequently associated (68.2%) and the serum cholesterol level was higher (213.0 +/- 55.2 mg/dl) than in diabetics without IBS (7.6 +/- 7.1 years, 32.1% and 192.1 +/- 44.8 mg/dl, respectively). By means of Stepwise Logistic Regression Analysis (SLRA), it was found that the strong risk factors were hypertension and serum cholesterol level. The serum triglyceride level, type of DM and response to diabetes treatment were also thought to be risk factors of IBS by the retrial of SLRA of residuals after exclusion of hypertension and serum cholesterol level. IBS was not significantly related to the duration of DM, fasting blood glucose level, body weight, glycosylated hemoglobin value, and serum high-density lipoprotein-cholesterol level.
