This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

A putative polypeptide hormone identified as amylin[islet amyloid polypeptide] is synthesized and co-localized with insulin in B cells of pancreatic islets in several animal species including man. However, there is growing evidence that somatostatin cells are also expressed and contained amylin in the pancreatic islets of the rat The aim of the present study was to investigate the immunocytochemical expression of the amylin within the endocrine pancreas of the man, rabbit and guinea pig, with special reference to the possible ability of islet cells other than insulin cells to synthesize amylin. For this purpose serial sections of the pancreatic islets were stainedimmunocytochemically using anti-amylin, anti-insulin, anti-glucagon, anti-somatostatin antisera. In serial sections of pancreatic islets of the man and rabbit, it was shown that amylin immunoreactivity occurred in insulin-reactive B cells predominantly located in interior of the islets. In contrast, amylin immunoreacivity appeared in glucagon-reactive A cells peripherally located in the islets of the guinea pig. These results suggest that in both the man and rabbit, amylin is synthesized by B cells for subsequent co-secretion with insulin, and that in guinea pig, amylin is synthesized by A cells for co-secretion with glucagon. It thus appears that amylin release may be mediated by different secretory mechanisms according to animal species.

Acute generalized exanthematous pustulosis (AGEP) has symptoms of abrupt onset of a widespread pustular eruption on an erythematous. base. Most cases appear to be related to drug reactions, mainly antibiotics, but viral infections and hypersensitivity to mercury may cause AGEP. The essential features of AGEP include. (1) numerous (several dazen) small((5mm), mostly non follicular pustules arising on a widespread erythema:purpura and target-like lesions may be associated; (2) histology showing intraepidermal or subcorneal pustules associated with one or more of the following.clermal edema, vasculitis, perivascular eosinophils, or focal necrosis of keratinocytes; (3) fever (over 38C); (4) neutrophilia, and (5) acute evolution with spontaneous resulotion of pustules within 15 days. We report a case of AGEP which presented with widespread tiny pustules on the whole body except the face, palms and soles. There were petechia, purpura, and vesiculobullous lesions on the axilla, popliteal fossa and upper abdomen. A biopsy specimen from a pustule showed subcorneal pustules with perivascular polymorphous cellular infiltration, marked dermal edema and necrotic keratinocytes. There was complete resolution of the lesions within 10 days.

BACKGROUND: Keloids may occur at any age, but tend tend velop between the ages of 10 and 30. The incidence and median age of onset are equal for both sexes. Keloids are common among the darker pigmented rices, but there have been a few clinia studies of keloids in Korea. OBJECTIVE: The purpcse of this study was to evaluate the variable clinical characteristics of keloids in Korea. METHODS: This clinical investigation was made with 223 of patients of keloid who had visited the Department of Derrnatology, Chonnam University Hosptal from January 1984 to December 1993. RESULTS: 1.The annual incidenie averaged over 10 years was 0.831 (361 cases of total 43,752 outpatients). 2.The ratio of male to female was 1: 0.94(Male. 115, Feila 108). 3.The mean age of the onset and at the first visit to our hospital were 24.5years and 29.2 years respectively. 4.In our series tte presternal area was the most commor saes, the shouder region next. Most keloids on the shoulder were related to BCG vaccination in ifoncy or chilhood. 5.The precipitating fa ctors associated with keloid were riaeeding dermatologic diseases(33.2 %), unknown(17.9%) rejection & vaccination(15.2%), operation(13.9%), burn(13.9%) and laceration(5.8%) in descending order. 6.Among preceeding as, iociated dermatologic diseases, acne w s the most common. 7. A positive family history is more likely in cases of mitile keloidal (p<0,001), and severe keloidal formation. 8.Most patients did not. complain of any symptorns(45.3%) nd a symptom of pain or tenderness(40.8%) was piesert rather than pruritus(13.9%). 9.The most prevaent tr eatment modality was intralesional injection with triamcinolone acetonide (84.3%). CONCLUSION: According, to this study, usually keloids occore in patients between 10 and 29 years of age, and most keloids were located on the antetio partion of the chest, shoulders, and face and scalp. A positive family history is more likely in as of multiple, severe keloidal for mation.
