  • Oral submucous fibrosis (OSF) is a premalignant condition characterized by juxtaepithelial fibrosis of the oral cavity. The clinical manifestations include burning sensation to spicy food, blanched oral mucosa with palpable fibrous bands, trismus, depapillation of tongue, and dry mouth. As OSF is predominantly seen in people of the Indian subcontinent, cases of this disease have been rarely reported in South Korea. We present a case of OSF in a Sri Lankan man living in South Korea and emphasize the importance of enhancing knowledge of this disease while the number of immigrants is increasing.

  • Hollow type suppositories inserted polyvinyl alcohol (PVA) hydrogel capsule containing propranolol·HCI (PPH) were prepared using different bases, polyethylene glycol (PEG), Witepsol H-15 (WH-15) and Witepsol W-35 (WW-35) to improve the controlled release of PPH. The release of PPH from the hollow type suppository inserted PVA hydrogel capsule was retarded than that from PEG, WH-15, or WW-35 hollow type suppositories in rat rectal cavity. When the suppositories were administered to rats, the controlled release of PPH was proved by the plasma concentration-time-profiles of PPH. No significant difference (p〈0.05) among the three different hollow type suppositories was observed in terms of AUC and MRT of PPH. WH-15 hollow type suppository inserted 12% of PVA hydrogel capsule caused irritation to rat rectal mucosa. However, the WH-15 hollow type suppository inserted PVA hydrogel capsule caused no severe irritation on rectal mucosa. The application of the hollow type suppositories using PVA in sustained rectal delivery of drugs might be feasible.

  • The buccal mucosa is an effevtive and versatile intraoral grafting material. For adequate reconst ruction of avulsed lip, restoration of natural appearance and adequate lip function should be done. We treated avulsed upper lip defect which had been affected underlying orbicularis oris muscle as well as vermilion border. We chose cheek mucosa for upper lip reconstruction and performed surgical correction of avulsed upper lip with pedicled buccal mucosal flap. The result was very good because of its superior color and texture matching to remaining yermilion tissue.

  • Taxa in the order Chlorococcales inhabiting Hongcheon River, South Korea were collected and identified from December 2011 to September 2012. As a result, nine taxa in the Order Chlorococcales including unrecorded genera Oocystidium and Heleococcus were newly added to the Korean flora: Oocystidium ovale, Heleococcus mucicola, Chlorella mirabilis, Monoraphidium convolutum var. pseudosabulosum, M. minutum, Raphidocelis mucosa, Eutetramorus tetrasporus, Scenedesmus flavescens, and S. multicauda. The morphological characteristics of the nine taxa identified in this study mostly corresponded to already reported characteristics; however, M. minutum had a shorter cell length than the recorded description, Raphidocelis mucosa and S. flavescens were larger than previous descriptions, and Scenedesmus multicauda had larger spines than the cell itself. Eight of the nine taxa were found in planktonic samples, whereas Heleococcus mucicola was found in an epilithic sample. Therefore the Korean order Chlorococcales, including these newly reported ones, totals to 255 species.

  • The buccal mucosa was observed histochemically in male rats which were injected with methionine. The staining methods were proceed by means of periodicacid-Schiff reaction, toluidine blue stain, alloxan-Schiff reaction, Mallory's aniline blue stain, Lillie's modification of Bielschowsky method and hematoxylin-eosin stain. The results of the experiment were summarized as follows: 1) PAS reactions of basement membrane and lamina propria increased after 3 and 5 days of methionine administration. 2) Metachromasia of stratum spinosum increased after 3 days of methionine administration. 3) Alloxan-Schiff reactions of stratum granulosum and stratum spinosum increased after 7 days of methionine administration. 4) In the lamina propria, aniline blue staining of collagenous fibers increased after 7, 10 and 14 days of methionine administration.

  • The effect of maltitol admininstration to rat was studied on breakdown of ${\alpha}-glycoside$ linkage with intestinal mucosa or pancreatic enzymes and induction of hepatic polyol dehydrogenase activities. Maltitol was contained as 13% or 26% in diet, and was administrated to rat for 9 weeks. This report carried out that ${\alpha}-glycoside$ linkage of maltitol was not hydrolyzed with pancreatic enzymes and intestinal mucosa. Maltitol dehydrogenase was not obeserved in liver cytoplasm, and hepbtic sorbitol dehydrogenase was not induced by maltitol administsation. Also, the effect of maltitol on aging of aluminum hydroxide gel, prepared by the reaction of aluminum chloride solution with strong ammonia solution to final pH 7.0, was studied by potentiometric titration, pH and acid-consuming capacity. Gel containing 1% or 2% maltitol was lost less than 2% of their acid-consuming capacity during a 120 days aging period compared with a loss of more than for an identical gel without maltitol and gel containing 0.5% maltitol.

  • Proper hygienic care of removable dentures is an important means of maintaining a healthy oral mucosa on denture wearers. Denture cleansing is often poor due to improper mechanical and the inefficient chemical cleansing of dentures. Dentists and patients should realize that microbial plaque on dentures may be harmful to both the oral mucosa and the patient's general health. This literature review was aimed to evaluate materials and methods for cleansing dentures and to discuss different means of keeping dentures plaque-free. A routine denture cleansing regimen should be designed to remove and prevent reaccumulation of microbial plaque and also to remove mucin, food debris, calculus, and exogenous discoloration. The combined use of chemical and mechanical cleansing is highly recommended for patients to clean their denture effciently.
