  • We treated a rare case of TO that presented with recurrent massive hemoptysis that resulted in total obstruction of the bronchus intermedius by very large blood clots. Bronchoscopic intervention resulted in a full recovery from the atelectasis. However, there are no guidelines for preventing recurrence of the hemoptysis or disease progression. Conservative and expectant management are used to treat these patients and most do well.

  • Angiogenesis is one of the essential processes that occur during wound healing. It is responsible for providing immunity as well as the regenerative cells, nutrition, and oxygen needed for the healing of the alveolar socket following tooth extraction. The inappropriate removal of formed blood clots causes the undesirable phenomenon of alveolar osteitis (AO) or dry socket. In this review, we aimed to investigate whether enhanced angiogenesis contributes to a more effective prevention of AO. The potential pro- or anti-angiogenic activity of different materials used for the treatment of AO were evaluated. An electronic search was performed in the PubMed, MEDLINE, and EMBASE databases via OVID from January 2000 to September 2016 using the keywords mentioned in the PubMed and MeSH (Medical Subject Headings) terms regarding the role of angiogenesis in the prevention of AO. Our initial search identified 408 articles using the keywords indicated above, with 38 of them meeting the inclusion criteria set for this review. Due to the undeniable role of angiogenesis in the socket healing process, it is beneficial if strategies for preventing AO are directed toward more proangiogenic materials and modalities.

  • Tissue factor (TF, tissue thromboplastin) is a membrane bound glycoprotein, which acceler-ates the blood clotting, activating both the intrinsic and the extrinsic pathways to serve as a cofactor for activated factor VII (Vila). The TF-factor Vila complex (TF/VIIa) proteolytically activates factors IX and X, which leads to the generation of thrombin and fibrin clots. In order to isolate TF inhibitors, by means of a bioassay-directed chromatographic separation technique, from the leaves of Eriobotrya japonica Lindley (Rosaceae), a known sesquiterpene glycoside (2) and ferulic acid (3) were isolated as inhibitors that were evaluated using a single-clotting assay method for determining TF activity. Another sesquiterpene glycoside (1) was also isolated but was inactive in the assay system. Compound 3 was yielded by alkaline hydrolysis of compound 2. The structures of compounds 1, 2, and 3 were identified by means of spectral analysis as $3-O-{\alph}-L-rhamnopyranosyl-(1{\rightarrow}4)-a-L-rhamnopyranosyl-(1{\rightarrow}2)-[{\alph}-L-rhamnopyrano-syl-(1{\rightarrow}6)]-{\beta}-D-glucopyranosyl nerolidol$ (1), $3-O-{\alph}-L-rhamnopyranosyl-(1{\rightarrow}4)-{\alph}-L-rhamnopyr-anosyl-(1{\rightarrow}2)-[{\alph}-L-(4-trans-feruloyl)-rhamnopyranosyl-(1{\rightarrow}6)]-{\beta}-D-glucopyranosyl$ nerolidol (2) and ferulic acid (3), respectively. Compounds 2 and 3 inhibited 50% of the TF activity at con-centrations of 2 and $369{\;}\mu\textrm{m}/TF$ units, respectively.

  • Objective: Stress is assumed to have many effects on menstruation of highschool senior female students, and it is expected to cause many problems and low efficiency during their studies. Therefore, through analyzing the menstruation state of highschool senior female students, the effects of stress on their menstruation and their education were studied. Methods: We made a survey of 583 senior female students of 'N' highschool located in Taegu. The survey was composed of the degrees of stress they were undergoing, menstrual problems caused by stress. Results: The survey results showed that 96.7% of the candidates were experiencing stress. 51.6% of them experienced an altered menstrual cycle, and menstrual irregularity was brought out in 32.1 % among them. 18.1 % of them were experiencing dysfunctional uterine bleeding. In sustaining period of menstruation, 17.5% of them had a shortened menstruation period, and 8.9% had a prolonged period. In case of menstrual quantity, less than normal quantity was reported by 26.9% of respondents and more than normal quantity was reported by 8.8%. 26.6% of respondents reported their menstrual blood was impure and the color was dark. Blood clots were increased in 27.5% of respondents. 86.6% went through premenstrual syndrome, and 34.3% had worsened menstrual pain. Studying was affected by menstrual pain in 83.9% of respondents. Of treating the disorder, 66.2% of them said they just waited till the pain went away, and 26.9% of them said they went to a pharmacy, and 2.4% of them said they went to an oriental medical clinic. Conclusions: From the above results, it is concluded that stress has a close connection with menstrual disorders. And it affects senior highschool female students' education, while they don't take proper treatments. Hence we think that we must have a lot of concern about senior female students and they must receive proper treatments.

  • Statement of problem: In cases where bony defects were present, guided bone regenerations have been performed to aid the placement of implants. Nowadays, the accepted concept is to isolate bone from soft tissue by using barrier membranes to allow room for generation of new bone. Nonresorbable membranes have been used extensively since the 1980's. However, this material has exhibited major shortcomings. To overcome these faults, efforts were made to develop resorbable membranes. Guided bone regenerations utilizing resorbable membranes were tried by a number of clinicians. $Bio-Gide^{(R)}$ is such a bioresorbable collagen that is easy to use and has shown fine clinical results. Purpose: The aim of this study was to evaluate the histological results of guided bone regenerations performed using resorbable collagen membrane($Bio-Gide^{(R)}$) with autogenous bone, bovine drived xenograft and combination of the two. Surface morphology and chemical composition was analyzed to understand the physical and chemical characteristics of bioresorbable collagen membrane and their effects on guided bone regeneration. Material and methods: Bioresorbable collagen membrane ($Bio-Gide^{(R)}$), Xenograft Bone(Bio-Oss), Two healthy, adult mongrel dogs were used. Results : 1. Bioresorbable collagen membrane is pure collagen containing large amounts of Glysine, Alanine, Proline and Hydroxyproline. 2. Bioresorbable collagen membrane is a membrane with collagen fibers arranged more loosely and porously compared to the inner surface of canine mucosa: This allows for easier attachment by bone-forming cells. Blood can seep into these spaces between fibers and form clots that help stabilize the membrane. The result is improved healing. 3. Bioresorbable collagen membrane has a bilayered structure: The side to come in contact with soft tissue is smooth and compact. This prevents soft tissue penetration into bony defects. As the side in contact with bone is rough and porous, it serves as a stabilizing structure for bone regeneration by allowing attachment of bone-forming cells. 4. Regardless of whether a membrane had been used or not, the group with autogenous bone and $Bio-Oss^{(R)}$ filling showed the greatest amount of bone fill inside a hole, followed by the group with autogenous bone filling, the group with blood and the group with $Bio-Oss^{(R)}$ Filling in order. 5. When a membrane was inserted, regardless of the type of bone substitute used, a lesser amount of resorption occurred compared to when a membrane was not inserted. 6. The border between bone substitute and surrounding bone was the most indistinct with the group with autogenous bone filling, followed by the group with autogenous bone and $Bio-Oss^{(R)}$ filling, the group with blood, and the group with $Bio-Oss^{(R)}$ filling. 7. Three months after surgery, $Bio-Gide^{(R)}$ and $Bio-Oss^{(R)}$ were distinguishable. Conclusion: The best results were obtained with the group with autogenous bone and $Bio-Oss^{(R)}$ filling used in conjunction with a membrane.

  • Purpose: The purpose of this study was to evaluate the bone regeneration of particulated hydroxyapatite(HA) and block type of hydroxyapatite graft in rabbit calvarial defects. Methods: An 8 mm calvarial circular defects were created in sixteen young adult New Zealand white male rabbits (weight $3.0{\sim}3.5kg$). Each defects were filled with Bio-Oss, particulated HA and block type HA. Sham surgery control defects were filled with blood clots. The specimens were harvested at 4 weeks and 8 weeks for histologic and histomorphometric evaluation. Results: Histomorphometric analysis demonstrated statistical differences in defect closure, new bone formation, and bone density of the four groups. Block type of HA group showed increased bone formation and bone density at 4 weeks and 8 weeks compared with Bio-Oss group or sham surgery control group(p<0.05). Conclusions: Block type of HA is an effective material for osteoconduction in rabbit calvarial defects, which may acts as a guide in use of these products in human application.

  • Fibrin clots of blood vessels are one of the serious factor caused cardiovascular disease. The development of a antithrombotic and thrombolysis solvent is necessary to prevent and treat these diseases. It has been reported that a strong fibrin-specific fibrinolytic enzyme was produced from a Korean fermented soybean paste similar to Japanese miso. We have been screened the known or novel fibrinolytic enzymes by activity-based and sequence-based screening from soil DNA metagenome library containing all kinds of environmental genomic DNA. The activity-based screening was determined the protease activity on 0.5% skim milk. For sequence-based screening, we designed a set of primer expanding gene sequence of fibrinolytic enzyme, performed PCR and selected clones showing the expected size of amplicons from metagenome library. Transformation of the gene encoding fibrinolytic enzyme was carried out with commercial vectors and their transformants were selected. Finally, we found 15 positive clones from metagenome library. Then each of sequences were analyzed and identified as similar or known the clones of nattokinase. We are going to perform full sequence of each clones, ligate with expression vector, transform into competent cells and then determine activity of expressed enzymes.

  • Gingivectomy has been utilized as a therapeutic method to remove diseased periodontal pocket wall in order to aid in root planing. Although chemical agents and electrosurgery has been used in addition to the conventional method of using surgical blades, difficulties in controling the depth of chemical penetration and effectively regenerating the gingival tissue as well as the slow wound healing has been pointed out as shortcomings of these methods. This study was designed to assess the effect of Aloe vera on wound healing of gingivectomy sites created by $CO_2$ laser on palatal gingiva of maxillary molar region of white rats. Those sites treated by surgical blades were designated as control, by $CO_2$ laser as Experimental group I, by surgical blades in addition to topical application of Aloe vera as Experimental group II, and by $CO_2$ laser and Aloe vera application as Experimental group III. Animals were sacrificed at 2 days, 3 days, 1 week, 2 weeks and 3 weeks postoperatively, and the specimens were histologically analyzed. The results were as follows : 1. Resorption of blood clots were observed in the control at 3rd day, followed by the rest of the experimental groups at 1 week postoperatively. 2. Persistent inflammation was observed up to 1 week in the control and Experimental group II and III, and until the 2nd week in Experimental group I. 3. Granulation tissue was observed up to 1 week in the control, and 2 weeks in the rest of the groups. 4. Epithelization started on the 2nd day. The control showed the most rapid epithelization, and the process was completed by the 2nd week in all groups. 5. Experimental group II and III, which were treated with Aloe vera, showed similar healing patterns to the control and Experimental group I.

  • This study was undertaken to evaluate the pulpal responses to the pulp-capping materials such as glutaraldehyde and formocresol in pulpotomy technique, especially in the primary dentition. Mandibular primary canines and molars of 5 dogs (aged about 8-9 weeks)were selected for this study. The intervals of observation for histologic study of pulpotomized primary teeth with 2% glutaraldehyde, formocresol and calcium hydroxide in the usual manner ranged from 2 hours, 1 week, 2 weeks, 3 weeks and 5 weeks after experiments respectively. Each specimens were fixed with 10% formalin and decalcified in 5% nitric acid. All slides were stained with Hematorylin-Eosin and examined histopathologically. The results were as follows; 1. In calcium hydroxide groups, formation of dentin bridge was initiated in 1 week after experiments and completed in 5 weeks after experiments. 2. Formation of dentin bridge was not seen, whereas necrosis of pulp tissue was noted, in formocresol and glutaraldehyde groups. 3. Duration of tissue reactions and tissue changes were similar, in formocresol and glutaraldehyde groups. 4. In formocresol and glutaraldehyde groups, amputation surfaces of the pulp were covered with blood clots, beneath which coagulation necrois was noted, but inflammatory cells were not prominent, in 2 hours and 1 week after experiments. But coagulation necrosis was proceeded to the apical portion, accompanied by infiltration of inflammatory cells, since 2 weeks after experiments. And suppuration or gangrene of the pulp tissue were noted in 3 weeks and 5 weeks groups. 5. Suppuration or gangrene of pulp seemed to provoke the resorption of dentin wall, and inflammatory changes and resorption of roots were noted in the periodontal membrane near the periapical region. 6. As compared with calcium hydroxide groups, resorption of the root was pronounced in form or cresol and glutaraldehyde groups. Effects of medicaments to the succedaneous tooth germ were not seen.
