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.

Background: Gastric juice volume and acidity are influenced by food, drugs, and patient factors such as age, sex, weight, and fasting time. But almost studies were performed without controlling of these confounding variables. This study was designed to determine the change of gastric juice volume and acidity in relation to the fasting time within a constant food intake. Methods: Fifty-seven healthy patient randomly allocated to one of two groups. Group I was instructed to ingest 200 ml of milk up to 8 hours before anesthesia and Group II was instructed to drink 200 ml of water up to 1~2 hours before anesthesia. After the endotracheal intubation the volume and acidity of gastric juice were measured. Relationships between gastric volume or acidity and fasting time were analysed using correlation analysis. The data were analyzed using Wilcoxon rank sum test, comparing Group I with Group II. Results: There is no significant relationship between gastric juice volume or acidity and the fasting time within the same food intake. Gastric juice volume and acidity of the patients who ingested milk at 8~9 hours before anesthesia were similar to that of those patients who drank water at 1~2 hours before anesthesia. Conclusion: It is necessary to individualize the fasting time of the patients and it seems that water ingestion up to 1~2 hours before anesthesia may be safe.

Both spindle cell variant of squamous cell carcinoma and atypical fibroxanthoma are most commonly presented as a solitary, often ulcerated nodule, occurring on sun-exposed skin of the elderly. These lesions also share the histologic features of diffuse or indistinct fascicular arrangement of polygonal or pulmp spindle cells. Therefore it is not easy to differentiate immunohistochemistry is done. A case of 73 year old woman with squamous cell carcinoma of the skin resembling atypical fibroxanthoma is presented.

sodium hyaluronate in beagle dogs. METHODS:In group 1, hGH(Eutropin, r-hGH) 0.29mg/kg was injected subcutaneously to 6 beagle dogs everyday for 7 days. In group 2, 1mg/kg in sustained- release formulation using sodium hyaluronate(SR-hGH), was injected subcutaneously to 6 beagle dogs. In group 3, 2mg/kg of the same formulation(SR-hGH) was injected subcutaneously to 6 beagle dogs. Blood samplings were done for the measurement of GH and IGF-1 concentrations with ELISA kit(Diagnostic Systems laboratories, Inc., USA) RESULTS:GH concentration in group 1 was below 0.5ng/ml before injection and elevated to 98.1+/-15.7 at 1 hr, 124.2+/-15 at 2 hr, 57.8+/-18.1 at 4 hr, 23.8+/-4.8 at 6hr, 10.8+/-3.7 at 8 hr, 2.8+/-1.6 at 10 hr, 1.0+/-0.7 at 12 hr, and 0.5+/-0.1ng/ml at 24hr after injection. Peak GH concentration was observed in 2 hr and thereafter decreased progressively and returned to basal level at 10 hr after injection. From the 2nd day GH concentration was measured only at 6 hr after daily GH injection, indicating the values of 20.9+/-8.7, 16.2+/-14.9, 23.1+/-8.5, 34.3+/-9.9, 16.1+/-7.0, and 21.8+/-13.0ng/ml at 2nd, 3rd, 4th, 5th 6th, and 7th day, respectively. GH concentrations in group 2(SR- hGH 1mg/kg) were 136.7+/-22.8 at 1hr, 149.3+/-29.9 at 2hr, 110.6+/-17.8 at 4hr, 103.7+/-18.2 at 6hr, 108.3+/-21.0 at 8hr, 91.4+/-21.4 at 10hr, 79.6+/-15.9 at 12hr, 23.7+/-8.3 at 24hr, 5.5+/-1.5 at 30hr, 0.7+/-0.2 at 48hr, 1.4+/-1.4 at 54hr, and 0.5+/-0.1ng/ml at 72hr after injection. GH concentration was elevated above the basal level for 72hr with the peak at 2hr after injection of SR-hGH of 1mg/kg. GH concentrations in group 3(SR-hGH 2.0mg/kg) were 196.7+/-45.2 at 1hr, 219.4+/-39.8 at 2hr, 198.1+/-38.0 at 4hr, 196.0+/-31.4 at 6hr, 179.2+/-28.3 at 8hr, 151.8+/-19.5 at 10hr, 141.3+/-23.1 at 12hr, 72.9+/-14.7 at 24hr, 43.7+/-14.2 at 30hr, 3.8+/-1.6 at 48hr, 1.6+/-0.5 at 54hr, 0.8+/-0.5 at 72hr, 0.5+/-0.1 at 78hr, and 0.5+/-0.2ng/ml at 120hr. Peak GH concentration occurred at 2hr after injection and remained high concentration till 72hr and returned to basal level thereafter. IGF-1 concentrations in group 1 changed from 190.5+/-68.1ng/ml before injection, to 326.4+/-96.2, 346.4+/-79, 391.4+/-86.9, 417.0+/-96.1, 422.1+/-92.0, 429.9+/-86.4, and 478.0+/-90.2ng/ml at 12hr, 30hr, 54hr, 78hr, 102hr, 126hr, and 150hr, respectively. IGF-1 concentrations in group 2 were 128.5+/-37.0 ng/ml before and 268.0+/-64.2, 307.6+/-63.1, 374.8+/-55.3, 335.5+/-39.4, 301.9+/-44.8, 288.5+/-42.5, 272.8+/-51.8, 273.9+/-46.0, 251.1+/-40.9, and 239.2+/-45.0ng/ml at 24hr, 30hr, 48hr, 54hr, 72hr, 78hr, 96hr, 102hr, 126hr, and 150hr, respectively after injection. Peak IGF-1 concentration was measured at 48hr and remained in high concentration till 150hr after injection. IGF-1 concentrations in group 3 were 116.0+/-68.9ng/ml before and 365.5+/-118.6, 400.0+/-135.1, 463.6+/-138, 450.2+/-140.0, 337.2+/-122.4, 301.4+/-113.4, 236.3+/-89.1, 226.3+/-75.5, 148.9+/-55.2, and 129.8 48.4ng/ml at 24hr, 30hr, 48hr, 54hr, 72hr, 78hr, 96hr, 102hr, 126hr, and 150hr, respectively after injection. Peak IGF-1 concentration was at 48hr and remained in high concentration till 150 hr after injection. There was no significant difference in IGF-I conc between group I and group 3. CONCLUSION: Sustained-release form(1mg or 2mg/kg) of hGH with sodium hyaluronate released GH for 72 hours with the peak level at 2 hours and higher concentration of IGF-I above baseline maintained for 150 hour after injection with peak level at 48 hour. There was no difference in IGF-1 concentration between SR-hGH 1mg/kg and 2mg/kg injection. So sustained release form 1mg/kg will be more effective for GH therapy as weekly injection mode. More extensive study is needed to permit for new therapeutic application.

Aortic transection or interruption is a rare condition which developed after an acute deceleration injury. Its occurrence depends on the location and direction of the force applied and is usually from motor vehicle accident or falling down. The exact incidence of aortic transection in trauma is not known but, when develops, only about 10-15% of the victims can furtive and be transported to the hospital. Even in the survivors, majority of them will be fatal within a few days if a prompt diagnosis and surgical treatments are not made. Aggressive diagnostic work-up is recommended for the patients with high suspicious index, which would salvage the victims with this fatal condition. We report the experience of two cases of aortic transection or interruption following motor vehicle accidents.
