Sebaceous carcinoma is uncommon and usually presents in the ocular adnexa as a cancer of the meibomian glands. They are frequently mistaken for chalazion. Considerable time often elapses before a diagnosis is made. We present a case of sebaceous carcinoma of the left eye lid in 59 year old female who had a history of 3 repeated surgical resections clinically diagnosed as chalazion during last 3 years.

Recent development of oral and maxillofacial surgery has taken an interest in the regeneration of facial bone defects. For the reconstruction of bony defects, autogenousbone grafts have been widely used. However, there are some clinical problems ; the morbidity of donor sites, resorption of autogenous bone graft and the availability of the proper form and size. The purpose of this study is to find the proper filling materials for the bone defects. The present study was designed to evaluate the roles and regenerating capacity of maikture of freeze-dried domineralized allogenic bone and hydroxylapatite. Fifteen adult New Zealand white rabbits were used as the experimental animal, Four trephine defects were made by drilling on the parietal bone of each rabbit. The size of each defects was 8x8mm. In first group, the defect was filled with freeze-dried demineralized allogenic bone and hydroxylapatite. The defect in second group was filled with autogenous bone chip only. The third group was filled with autogenous bone chip and hydroxylapatite. The fourth group was filled with freeze-dried dimineralized allogenic bone only. The results were carefully examined grossly and micorsocopically from the 2 weeks to 12 weeks postoperatively. The following results were obtained ; 1. In the case of the graft with autogenous bone chip only, new bone formation was more active than any other groups. 2. In the case of the graft with combination of freeze-dried demineralized allogenic bone and hydroxylapatite, new bone formation was similar to the case of autogenous bone and hydroxylapatite mixture. 3. In the case of the graft with freeze-dried demineralized bone, new bone formation was observed, but less than the other groups. And the time of new bone appeared was later than the other groups. A combination of freeze-dried deminearalized allogenic bone and hydroxylapatite plays an effective role in forming new bone. The results of this study may suggest the possible usage of the mixture of freeze-dried allogenic bone and hydroxylapatite as an alternative to autogenous bone in maxillofacial orthopedic surgery.

Fibrofolliculoma is a benign follicular neoplasm which usually occurs in multiple and rarely solitarily. We have found only seven cases of previous reports of solitary fibrofolliculomas worldwide and only two in Korean literature. Herein we report on a 40-year-old female patient with a solitary flesh-colored bean sized mass on the scalp which histopathologically proved to be a fibrofolliculoma.

Endodermal sinus tumors are an uncommon malignancy in children and occur most often in the gonads and sacrococcygeal region. In these locations, thy are found as primary tumors ; in teratoma they form part of the malignant component. We present CT and MR imaging findings in two cases of endodermal sinus tumor occurring after the resection of a mature benign cystic sacrococcygeal teratoma during the neonatal period. Awareness of the transformation of a benign cystic teratoma to a different type of malignant germ cell tumor may be helpful in the evaluation of sacrococcygeal masses.

Apoptosis (or programmed cell death) is defined by morphologic changes induced by a spectrum of physical and chemical agents. resulting in non-pathologic cell loss, which is relevant to a range of biological processes, including differentiation, development, maturation, and injury of cells as well as immunologic function. In this study, we examined the frequency of apoptotic bodies and mitoses (apoptotic and mitotic indices) in the tissue samples of 35 patients of prostatic carcinoma, which were grouped according to the Gleason scores, and 5 cases of benign prostatic hyperplasia. The indices were determined as the numbers of apoptotic and mitotic bodies per 100 tumor cells in hematoxylin eosin stained section. The apoptotic bodies were confirmed by the in situ nick end labelling method. The apoptotic and mitotic indices were observed more frequently in prostatic carcinoma than the benign hyperplastic prostatic tissues with a positive correlation between the frequency of apoptotic bodies and Gleason scores in prostatic cancer. In conclusion, an increased programmed cell death was correlated with the increasing malignant potential (higher Gleason scores) in prostatic cancer.

BACKGROUND: It is important to avoid the direct contact with water of detergents as possible for the treatment and prevention of hand eczema. OBJECTIVE: The purpose of this study is to evaluate the protective effect of skin protector, Marly skin on housewifes eczema, METHODS: The patients with hand eczema apply skin protector, Maly skin, four times a day on their both hands. They are evaluated with the scores of subjective symptor is(itch, dryness, smarting) and objective signs(erythema, scaling, fissures), and skin replica which are taken from the specified site are analysed by using an image analyser and, scanning electron micrascipe. RESULTS: 4 weeks after application of skin protector, there are statstically significant decrease of total clinical symptom scores. Scanning electron microscopic findings of the skin replicas show marked changes between the beginning and the end of the study. On quantive image analysis of the skin replicas, the length of fissure is a little decreased and the depth of rrows is slightly increased than before application of skin protector, but these are not statistically significant. CONCLUSION: Skin protector, Marly skin, has a protective effect on the development of hand eczema.

The halophilic bacterium, Vibrio vulnificus, causes acute fulminating wound infections and septicemia in human. Especially the septicemia shows high mortality above 50%. In Korea, septicemia by V. vulnificus was reported at westem and southern coast in every year. Here, we try to isolate this V. vulnipcus at Kyoung-nam area and coast of Pusan during 1996. Purposed sites were Dadaepo, Songjung, Chungsapo and Mipo of Pusan and Kijang, Ilkuang, Juksoung, Dongam, Waljun and Chilam of southern sea. Total 40 strains of V. vulnipcus were isolated from sea samples. Biochemical characteristics of isolated V. vulnificus were almost same with reference strain V. vulnificus ATCC 27562 on Farmer's tests and on API 20E kit test. V. vulnificus isolates in 1996, fermented cellobiose and salicin but arabinose. and had resistance to 7% sodium chloride.
