The purpose of this study was to compare the accuracy of currently used elastomeric impression materials for complete arch impression taking. Five elastomers (Impregum, Permlastic, Express, Extrude, Examix) and one Irreversible hydrocolloid (Aroma-fine) were tested. For each material, 5 impressions were made of stainless steel model to which five tapered posts were attached. Custom trays were used for polyether and polysulfide impression materials, and putty/wash two step technique was used for addition polyvinylsiloxane impression materials. Improved stone models were poured to all impressions. Accuracy of the materials was assessed by measuring ten distances on stone dies poured from impressions of the master model. All measurements for master and improved stone models were with three dimensional measuring machine. The results were as follows 1. The dimensional accuracy of polyether, extrude, and examix were significantly superior to polysulfide, exress, and alginate in reproducing full arch mode (p<0.05). 2. There were no statistical differences in dimensional accuracy for full arch impression between polyether, extrude and examix (p>0.05). 3. there were no statistical differences in dimensional accuracy between polysulfide, express, and alginate (p>0.05). 4. There were no statistical differences between addition polyvinyl siloxane materials (p>0.05). 5. There were no statistical differences between anterior-posterior and lateral dimensional changes of all impression materials (p>0.05).

Plaster of Paris is an effective ancillary treatment in the surgery of infected cavities in bone. It is well tolerated and spontaneously absorbed over the period of weeks to months, being replaced by bone of normal architecture. When the antibiotics incorporated into plaster of Paris, the antibiotics are capable of prolonged local release in bactericidal concentrations. Therefore it is proposed that antibiotics loaded plaster of Paris might be a simple adjuvant technique after good surgical debridement for the treatment of bone infection. The authors carried out an experiment to study the effect of plaster of Paris containing antibiotics for a prevention of experimental osteomyelitis, using 45 rats, which were divided into 3 groups. In the Group 1, a defect was made at the proximal metaphysis of the tibia, inoculated by Staphylococcus aureus sensitive to Cephradine and Tobramycin and then filled with plaster of Paris pellet. In the Group 2, a defect was filled with Cephradine loaded plaster of Paris pellet. In the Group 3, a defect was filled with Tobramycin loaded plaster of Paris pellet. Then we observed the healing process of the bone defect in the point of view of the gross findings, radiologic findings and histologic findings at 4th, 8th and 12th week after operation. The results of this study were as follows:l. In the control Group;all 30 cases were infected. 2. In the Group 2;only 4 of 30 cases were infected. 3. In the Group 3;all 30 cases were not infected. 4. The plaster of Paris filled into the defect was absorbed continuously and stimulated the new bone formation.

BACKGROUND: Antihypertensive effect and safety of the newer, long acting, nonsulfhydryl angiotensin converting enzyme inhibitor, lisinopril, were studied. METHODS: Twenty eight patients of mild to moderate essential hypertension were administered 10-20mg of lisinopril once daily for ten weeks. Patients were evaluated every two weeks concerning the changes of blood pressure and pulse rate in the sitting position and also any untoward sumptoms and signs attributable to the side effect. Chest X-rey, ECG and laboratory examination were performed in principle two times before and after the completion of medication. RESULTS: The blood pressure declined from 165.4/107.6mmHg to 141.3/92.4mmHg at the end of ten weeks of medication, thus the reduction of 24.1mmHg of systolic pressure and 15.2mmHg of diastolic pressure were observed and the overall effective rate was 85.7%. The pulse rate and laboratory findings were not sigificantly changed before and after the administration of lisinopril. The side effects were observed in 2 cases(7.1%) of mild dry cough and in 2 cases(7.1%) of transitory mild headache and in 1 case(3.6%) of dizziness but no one discontinued medication due to adverse effects. CONCLUSION: Lisinopril proved effective and safe in the treatment of mild to moderate essential hypertension.

The purpose of our study is to evaluate the visual, refractive and IOP results following combined small incision phacoemulsification, foldable lens implantation, and fornix based trabeculectomy with Mitomycin-C. Seventy-six eyes of 64 patients with cataract and glaucoma had undergone the combined procedure. Minimal follow-up period was 6 months(mean 12.8+/-4.8 months). All the eyes that were free of preexisting macular disease and endstage glaucomatous optic nerve damage demonstated significant improvement in visual acuity. Postoperative astigmatisn was negligible(-0.41diopters). The average IOP reduction was 7.7mmHg. Functioning filtrating bleb persisted in 76.3% of the eyes. Complications with this method were not significant compared with other studies reporting the combined procedure. The small incison phacotrabeculectomy with mitomycin-C technique that we describe appears to be effective in early restoration of visual acuity and reduction of IOP without significant complications.

We recently encountered a case of pemphigus vulgaris, which was localized within the oral mucosa and esophagus. The patient was a 62-year-old women, who had had a few recurrent erosions on the oral mucosa for 1 year. Newly developed erythematous erosions on the esophagus appeared 7 days pre previously. Histopathological findings showed suprabasal blisters in the epithelium of the buccal and esophageal mucosa. On direct immunofluorescence, intercellular IgG and C3 bindings were found in the epithelium of the buccal mucosa. Treatment with oral steroids resulted in a remission of the lesions and the other skin lesions were not found for a period of 6 months.
