The purpose of this study is to observe histopathologic changes in the bilateral craniomandibular joints after allowing 6 weeks of consolidation by varying the amount of distraction in rabbit mandible. Eight rabbits weighing about 2 to 3kg were used. After corticotomy was performed on the left mandibular body between the first premolar and the second premolar region, a unilateral fixation device was placed. Then, a 7-day period was allowed without distraction of the device. The mandible was lengthened 0.5mm/day. Corticotomy and lengthening of mandible were not performed in control group. After the completion of the lengthening process, a 6-week-consolidation period was allowed. Then, the rabbits were sacrificed, and histologic examination of the craniomandibular joints was performed. Proliferative changes were observed in the craniomandibular joints in all groups. With the increasing amount of distraction, hypertrophy of the cartilage layer became more severe, bone formed was dense and enchondral ossification was clearly shown in subchondral bone. Hypertrophy of the cartilage layer was also seen in the non-distracted side as the distracted side in the experimental group. These results indicate that when physical force is applied constantly to joints, the proliferation of articular cartilage and bone formation are present. When more than 6 weeks of consolidation period is allowed at the time of performing distraction for more than 5mm, articular changes, especially, in the contralateral side should also be noted.

The place of excretory urography in the diagnosis of both renal and extrarenal lesions has been firmly established. Radiographic findings of the kidney by means of excretory urogram is no less important than any other functional study in the evaluation of clinicalconditions, such as atrophic kidney, hydronephrosis, renal tumor, renal hypertension and polycystic kidney. The present investigation was undertaken to establish the morphological features of the normal kidney in Korean adults of both sexes, such as size (length and width), renovertebral angle and distance, number of calices and position in the renal pelvis. 200 cases of normal intravenous pyelography were subjected to the present investigation. These materials were randomly selected from the X-ray file of St. Vincent's Hospital covering the period from Jan. 1979 to Dec. l980. There were 96 males and 104 females of normal health, and the age ranged from 20 to 54 years old, showing comparatively even distribution. The results were as follows: 1. Length: The mean values in males were 12.50 cm for the right side and 12.95 cm for the left side and those in females were 11.99 cm for the right side and 12.43 cm for the left side. The figures for both sides were about 0.5 cm larger in males than in females and the left side was about 0.5 cm larger in both sexes than the right side. 2. Width: The mean values in males were 6.24 cm for the right side and 6.60 cm, for the left side and those in females were 6.07 cm for the right side and 6.38 cm for the left side. The figure for the left side were wider than the right side about 0.4 cm in males and 0.3 cm in females, but there were no significant differences between the left side and the right side in both sexes. 3. Renovertebral angle: The mean values in males were 15.39 degrees for the right side and 15.40 degrees for the left side and in females the figures were 13.34 degrees for the right side and 13.47 degrees for the left side. There were no significant differences between the right and the left side in both sexes, but the angle in both sides were about 2 larger in the male than in the females. 4. Renovertebral distance: The mean values in males were 5.9 cm for the right side and 6.01 cm for the left side and in females the figures were 5.05 cm for the right side and 5.09 cm for the left side. There were no significant differences between the right and left and left side in both sexes, but the distance in both sides were about 0.9 cm larger in the males than in the females. 5. Number of the calices: The number of major calices was 2 to 4 and that of minor calices 5 to 13. The number of minor calices was 7 to 10 in 357 kidneys (89.3%). 6. Position in renal pelvis: An intrarenal pelvis was found in 263 cases (65.8%)and an extrarenal pelvis was seen in 137 cases (34.2%).

PURPOSE: To present the clinical outcomes of small incision lenticule extraction (SMILE) including visual quality analysis in Korean patients with myopia METHODS: The medical records of 228 eyes of 116 patients who underwent SMILE in HanGil Eye Hospital LASIK Center from May 2014 to Feb 2015 and were followed-up for at least 3 months was analyzed retrospectively. The patients were followed up at 1 day, 1 week, 1 month, and 3 months after the operation. Refractive value, visual acuity, intraocular pressure, and visual quality were measured at each visit RESULTS: Preoperatively, uncorrected distant visual acuity was 0.01 ± 0.02 in log MAR, spherical equivalent was -5.03 ± 1.72 diopters, intraocular pressure was 15.85 ± 2.85 mm Hg, and the objective scattering index (OSI) value was 0.68 ± 0.49. The postoperative uncorrected distant visual acuity was 0.13 ± 0.10, 0.05 ± 0.08, 0.04 ± 0.09, and 0.02 ± 0.04 and OSI was 2.16 ± 1.89, 1.25 ± 0.64, 1.14 ± 0.69, and 0.81 ± 0.36 at 1 day, 1 week, 1 month, and 3 months after the operation, respectively. The postoperative intraocular pressure was 12.55 ± 3.74 mm Hg, 13.03 ± 4.35 mm Hg, 11.65 ± 2.49 mm Hg at 1 week, 1 month, and 3 months after the operation. The efficacy of refractive surgery 3 months after the operation was 0.97 ± 0.11, the safety was 0.99 ± 0.10, and predictability was 99.56% and 100.00% at the range of ±0.5 diopters and ± 1.0 diopter, respectively. CONCLUSIONS: The SMILE operation showed comparable clinical outcomes with conventional refractive surgery in terms of efficacy, safety, and predictability. Intraocular pressure and visual quality normalized gradually throughout the 3-month postoperative period.

The results of TUR and open surgery in benign prostatic hyperplasia were compared in 72 cases of TUR and 48 cases of open surgery from July 1980 to June 1987. The results were as follows; 1. Mean operation time was shorter in TUR than open surgery(106.9min. in open surgery, 87.4min. in TUR). 2. Mean weight of resected prostate was heavier in open surgery than TUR(57.5gm in open surgery, 18.1gm in TUR). 3. Mean blood loss during operation was widely different between two groups(547.2ml in open surgery, 281.6ml in TUR), and no blood was required in 19.4% of TUR. 4. Mean hospitalization and catheter indwelling periods were shorter in TUR than open surgery(mean hospitalization ; 13 days in open surgery and 8.6 days in TUR). 5. Total complication rate was 25.1% in open surgery and 20.8% in TUR, the most predominant complication was rebleeding in open surgery and urinary incontinence in TUR.

In periodontal regeneration treatment, access to the frucation area is very difficult. Thus complete removal of plaque, calculus and endotoxin is somewhat impossible. In this study, teeth that were extracted due to periodontal disease were used. The furcation area was treated with periodontal curette, ultrasonic scaler, roto bur and they observed using SEM. The result was follows 1. The group treatment with curette showed remaining plaque, the cementum existed in most of the surface and partial dentinal tubule orifice could be seen. 2. The group treatment with ultrasonic scaler showed less removalof plaque compared to curette and irregular surface could be seen. 3. The group treatment with roto bur showed cleaner surface and many dentinal tubule orifice could be seen compared to the curette and ultrasonic scaler groups. Thus when suing treatments such as bone grafting or guided tissue regeneration, it is considered that the furcation area should be treatment with Roto bur.

The hemostatic effect of endoscopic microwave coagulation method for upper gastrointestinal bleeding was evaluated clinically. Hemostasis over 72 hours was achieved in 18 of 20 cases (90%) with upper gastrointestinal bleeding by the endoscopic microwave coagulation method. It is noteworthy that this method was effective in all 4 cases of pulsatile bleeding from exposed vessels. We conclude that this method is useful for emergency endoscopic hemostasis on upper gastrointestinal bleeding, especially bleeding from exposed vessels.

We report the first case of an angiomyomatous hamartoma (AH) of the popliteal lymph nodes (LNs) occurring in association with diffuse pigmented villonodular synovitis (PVNS) of the knee. AH is a rare benign vascular disease with a predisposition for the LNs of the inguinal region. Twenty-five cases of AH have been reported to date; however, the precise pathogenesis is still undetermined. In the present case, an open synovectomy revealed two of three popliteal LNs in close proximity to the extra-articular component of diffuse PVNS. These LNs demonstrated irregularly distributed thick-walled blood vessels in the hilum. These vessels extended into the medulla and cortex and were associated with haphazardly arranged smooth muscle cells in the sclerotic stroma. These findings are compatible with an AH. Our observations raise the possibility that AH of the popliteal LNs may represent an abnormal proliferative reaction against the inflammatory process caused by PVNS of the knee.

To elucidate iron utilization patterns of Staphylococcus aureus according to the growth, we checked the residual iron concentration and the production of siderophores at the indicated times while culturing S. aureus ATCC 6538 and 25923 strains in brain heart infusion broth. By using streptonigrin susceptibility test and investigating growth curves in three culture media of which iron concentration is 0.2, 20, 45 uM, respectively, we found out that iron metabolism of 6538 strain was more active than that of 25923 strain. In point of tendency of iron consumption, 6538 strain steeply consumed iron just before the onset of stationary phase, but 25923 strain did gradually iron throughout the growth phase. Nevertheless, total amount of iron consumed by each strain during the growth was almost no difference between the strains. CAS diffusion assay in detecting siderophores showed that siderophore production followed iron consumption. These results suggest that the siderophores play significant role in iron utilization in vitro.
