1.Histologic Correlation of Ultrasonic Layers of Surgically Resected Gastric Wall.
Journal of the Korean Radiological Society 1994;31(2):295-300
PURPOSE: To define the histologic correlation of the ultrsonic gastric wall layers of resected human gastric specimens. MATERIALS AND METHODS: UItrasound images of the gastric wall by using 5 or 7.5 MHz linear transducer were compared with the corresponding histologic sections of 30 surgically resected human gastric specimens. RESULTS: Five layers seen from within on ultrasound images of the normal gastric wall corresponded to (1) the acoustic interface between fluid bathing the surgical specimen and the mucosal surface and a portion of the superficial mucosa, (2) the deep mucosa including the muscularis mucosae and most of the superficial mucosa, (3) the submucosa plus the acoustic interface between the submucosa and the muscularis propria, (4) the muscularis propria minus the acoustic interface between the submucosa and the muscularis propria, and (5) the serosa and the subserosal tissue plus the acoustic interface between the serosa and the fluid bathing the surgical specimen. Ultrasonic findings in gastric carcinomas corresponded to their histopathologic findings. CONCLUSION: Histologic correlation of the ultrasonic gastric wall layers will provide us with a very useful and objective basis of gastric ultrasonography.

BACKGROUND: Isolated infraspinatus tear is very rare and clinical features are not as well known, therefore the purpose of this study was to evaluate clinical characteristics and outcomes of isolated infraspinatus tear that authors experienced. METHODS: Authors reviewed 288 cases of full-thickness rotator cuff tear involving infraspinatus between 2010 and 2015, and retrospectively analyzed six cases of isolated infraspinatus tear. Perioperative clinical characteristics, postoperative functional outcomes of 6 months were investigated. Functional evaluation included visual analogue scale (VAS), range of motions, American Shoulder and Elbow Surgeons (ASES) score, and Constant score. RESULTS: Calcific tendinitis was accompanied in 4 cases (66.7%). Three of them received steroid injection or aspiration or extracorporeal shockwave therapy. Mean preoperative pain VAS was 7.1 (range, 5–9), and mean postoperative pain VAS at 6 months later was 1.6 (range, 0–5). Preoperative muscle strength by isokinetic muscle performance test showed 52% deficit of abduction and 37.6% deficit of external rotation. All 6 patients had arthroscopic repair of the infraspinatus tendon. All the patients at the 6 months follow-up exhibited clinical improvement in the Constant score (67.8 [range, 45–77] to 89.3 [range, 81–100], p=0.029), and ASES score (52.3 [range, 30–77] to 90.0 [range, 80–100], p=0.002). There was no healing failure on imaging. CONCLUSIONS: Isolated infraspinatus tendon tear was frequently accompanied by calcific tendinitis, but pathophysiologic relationship should need more study. To rule out neurogenic etiology, magnetic resonance imaging and electromyography would be helpful. Arthroscopic infraspinatus tendon repair and supraspinatus debridement showed relatively good result in painful shoulder.

We analyzed the clinical result of trabeculectomy with amniotic membrane transplantation which has antifibrotic and antiinflammatory action in risky glaucoma patients. Subjects were included four eyes of four patients with neovascular glaucoma, one eye of one patient with primary open angle glaucoma and four eyes of three patients with congenital glaucoma. After limbal based scleral flap was made in triangular shape with 5x4 mm sized, amniotic membrane, sized by 6x6 mm with epithelial side up, was placed on the scleral flap and then sutured to medial and lateral portion at 3 mm superior to base of scleral flap base with 10-0 nylon(2 points). The state of bleb, intraocular pressure and complications were observed at postoperative 1st, 3rd, 6th and 9th week. The IOP was reduced from 33.6+/-11.1 mmHg, to 15.5+/-6.5 mmHg at postoperative one week, 17.0+/-8.3 mmHg at three weeks, 16.9+/-8.1 mmHg at six weeks, 17.1+/-6.4 mmHg at nine weeks. 6 eyes(77.7%)had controlled IOP under 21 mmHg without antiglaucomatous agents at last follow up. Avascular blebs were observed throughout postoperative period in all subjects. Postoperative complications were shallow anterior chamber in one eye at 1st week and low intraocular pressue in one eye at 1st, 3rd week, that resolved at six weeks. Trabeculectomy with amniotic membrane transplantation on the scleral flap appeared to be effective as an augment therapy for filtering surgery in risky glaucoma.

PURPOSE: We investigated the anti-inflammatory and anti-fibrotic effects of amniotic membrane(AM) ointment in filtering surgery of rabbits. METHODS: After filtering surgery was performed on both eyes of 10 rabbits, the AM ointment was applied over and under the scleral flap on one eye whereas base ointment excluding AM element was applied to the other as a control. The shapes of blebs were observed under slit-lamp biomicroscopy at postoperative 3 days, 1 week, 2 weeks and 4 weeks, and the tissues were excised for histologic studies. RESULTS: Serial changes of intraocular pressures had no significant difference. Slit-lamp biomicroscopy demonstrated that conjunctival blebs of AM ointment group were more elevated and cystic at 1 and 2 weeks. The heights of conjunctival blebs were significantly higher at 1, 2 and 4 weeks, and the width of scleral tracks was significantly wider at 1 and 2 weeks in AM ointment group. The number of inflammatory cells in the scleral track was significantly less at 3 days and 1 week, the number of fibroblasts in scleral track was significantly less at 2 and 3 weeks in AM ointment group. Masson s trichrome stain was less positive in AM ointment and the stain area of alpha-smooth muscle actin-positive fibroblasts was insignificant with image analysis system. Collagen type 3 appeared in scleral track from postoperative 1 week in control group, however, in AM ointment group, from 4 weeks. CONCLUSIONS: AM ointment is beneficial to suppress fibroblast differentiation, proliferation and inflam-matory reaction in filtering surgery and might be safe and effective adjunctive for enhancement of success in filtering surgery.

The purpose of this study was to evaluate the abrasion resistance of surface penetrating sealant which was applied on a composite resin restoration and to provide proper time to reapply sealant on composite resin surface. Two hundred rectangular specimens, sized 8 x 3 x 2 mm, were made of Micronew (Bisco, Inc., Schaumburg, IL, U.S.A) and divided into two groups; F group (n = 10) was finished with coarse and medium grit of Sof-Lex discs and BisCoverwas applied B group (n = 190) after finishing with discs. B group was again subdivided into nineteen subgroups. From B-1 group to B-18 group were subjected to toothbrush abrasion test using a distilled water-dentifrice slurry and toothbrush heads. B-IM group was not subjected to toothbrush abrasion test. Average surface roughness (Ra) of each group was calculated using a surface roughness tester (Surfcorder MSE-1700: Kosaka Laboratory Ltd., Tokyo, Japan). A representative specimen of each group was examined by FE-SEM (S-4700: Hitachi High Technologies Co., Tokyo, Japan). The data were analysed using cluster analysis, paired t-test, and repeated measure ANOVA. The results of this study were as follows; 1. Ra of F group was 0.898 +/- 0.145 microm and B-IM group was 0.289 +/- 0.142 microm. Ra became higher from B-1 group (0.299 +/- 0.48 microm) to B-18 group (0.642 +/- 0.313 microm). 2. Final cluster center of Ra was 0.361 microm in cluster 1 (B-IM ~ B-7), 0.511 microm in cluster 2 (B-8 ~ B-14) and 0.624 microm in cluster 3 (B-15 ~ B-18). There were significant difference among Ra of three clusters. 3. Ra of B-IM group was decreased 210.72% than Ra of F group. Ra of B-8 group and B-15 group was increased 35.49% and 51.35% respectively than Ra of B-IM group. 4. On FE-SEM, B-IM group showed the smoothest resin surface. B-8 group and B-15 group showed vertically shallow scratches, and wide and irregular vertical scratches on composite resin surface respectively. Within a limitation of this study, finished resin surface will be again smooth and glazy if BisCover would be reapplied within 8 to 14 months after applying to resin surface.
