Objectives: Korea has a dual medical system where traditional Korean Medicine (KM) and Western Medicine (WM) exist au equal terms with exclusive practice boundaries. The aim of this study was to identify complementary and substitute relationships between KM and WM in Korea. Methods: The data of 19,413 respondents were collected from the 2009 Korea Health Panel dataset. General characteristics and the medical utilization of respondents were analyzed descriptively. the Univariable Analysis was used to compare the factors that affected KM and WM utilization, and the Multivariable Analysis was applied to identify complementary or substitute relationships between the respondents' choices for KM and WM. The data were analyzed by the seven disease groups; diseases of nervous system, circulatory system, respiratory system, digestive system, skin and subcutaneous tissue, musculoskeletal system, and connective tissue, injury, poisoning and others. Results: 13.6% and 76.9% of respondents used KM and WM respectively last 12 mouths. 12.7% used both, and 0.9% used KM only. In overall, respondents who visited KM institutions used also WM. However, according to the analysis of choices of medical institutions, non-pharmacological KM treatment and WM has been used as a substitute for another in the diseases of the skin and subcutaneous tissue, diseases of the musculoskeletal system, and connective tissue, injury, poisoning and others. Conclusions: Despite some exceptional disease areas, Korean people use KM complementarily to WM, and this result can rationalize the recent Korean government policies encouraging the cooperation of KM and WM. This study can he used for the future policies development for KM service delivery.

A comparative study on the quality of meat from three breeds of goats reared in Bulgaria: Local Aboriginal (LA); Bulgarian White Dairy (BWD) and crossbreeds of local aboriginal with Saanen goats (LA ${\times}$ S). Eight intact young male goats from each breed have been included in the experiment. The animals from the three breeds have been reared under similar conditions. The animals have been slaughtered at the age of 2 months (at weaning) and at the age of 6 months (upon reaching sexual maturity). The following tests have been performed on samples of m. longissimus dorsi between $5^{th}$ and $6^{th}$ ribs: pH 45 min post mortum, colorimetrically color of meat, water holding capacity and fatty acid composition of the fat. The thickness of muscle fibre and the proportion of muscle, connective and adipose tissue have been microscopically determined at m. longissimus dorsi, m. semitendinosus and m. iliopsoas. After deboning and separating the bigger tendons, the chemical composition of the meat from the left half of the carcass has been determined. The results reveal lack of statistically significant differences among the three breeds concerning pH, the water holding capacity, color of meat, thickness of the muscle fibre and fatty acid composition of the fat. The carcass meat of crossbreeds of LA ${\times}$ S contains significantly more fat than the other two breeds. This influences the proportion of muscle, connective and adipose tissue in m. longissimus dorsi, m. semitendinosus and m. iliopsoas, resulting in more adipose tissue in the LA ${\times}$ S compared to young goats of the LA or the BWD. There are differences in slaughtering 2-month-old goats (at weaning) and 6-month-old ones (upon reaching sexual maturity). At a greater age the content of fat in the carcass increases, as well as the quantity of the adipose tissue, the intensity of the colour of the meat and there is a tendency towards thickening of the muscle fibre and increasing the water holding capacity of meat. The moisture content in meat decreases due to the increase of fat.

To verify the effect of subgingival calculus on the periodontal tissues in periodontitis and the effectiveness of supragingival scaling to remove the calculus, 30 teeth from healthy group (Probing pocket depth:$PPD{\leq}mm$: HP group), 15 teeth from moderate group ($4{\leq}PD<7mm$:MP group), 30 teeth from advanced group (PPD>7mm: AP group) were selected and supragingival scaling was performed before extraction of all experimental teeth. After careful extraction, the teeth were cleaned with saline and disclosed with toluidine blue and carefully examined the relationship and distance between the calculus attached on the root surface and periodontal tissues. As a result, it was; 1. The calculus was not discovered on the root surface of teeth in HP group, but was in MP and AP group, mostly on interproximal surface and furca area. The shape of the attached calculus was ovoid, trepazoid and polygonal and the calculus was distributed randomly over the root surface. 2. PPD was more than the distance between the gingival margin to the level of attached connective tissue in AP group rather than in HP and MP group. 3. The length of calculus was $2.7mm{\pm}.44mm$ in HP group and $4.1{\pm}.89in$ AP group. 4. The distance between the apical margin of calculus and the level of attached connective tissue was $2.4{\pm}.33mm$ in MP group and $3.4{\pm}.89mm$ in AP group. 5. The length of subgingival calculus was tended to increase in relation to the probing pocket depth. Therefore, it can be concluded, the calculus in periodontal pocket can not be removed completely with supragingival scaling. As the terminal part of calculus was far away with limited distance from the periodontal tissue, it can be said that the calculus was not a direct factor in destroying the periodontal tissue. In this study, the extent of the plaque was not verified but the location of calculus can be used in clinical practice for complete removal of calculus when the distance relation bewteen calculus and plaque will be known.

Purpose: In this study, we aimed to evaluate the clinical validity of the modified tunneling technique using minimal soft tissue harvesting and volume-stable collagen matrix in the anterior mandible. Methods: In total, 27 anterior mandibular teeth and palatal donor sites in 17 patients with ≥1 mm of gingival recession (GR) were analyzed before and after root coverage. For the recipient sites, vertical vestibular incisions were made in the interdental area and a subperiosteal tunnel was created with an elevator. After both sides of the marginal gingiva were tied to one another, a prepared connective tissue graft and volume-stable collagen matrix were inserted through the vestibular vertical incision and were fixed with resorbable suture material. The root coverage results of the recipient site were measured at baseline (T₀), 3 weeks (T₃), 12 weeks (T₁₂), and the latest visit (T_l). For palatal donor sites, a free gingival graft from a pre-decided area avoiding the main trunk of the greater palatine artery was harvested using a prefabricated surgical template at a depth of 2 mm after de-epithelization using a rotating bur. In each patient, the clinical and volumetric changes at the donor sites between T₀ and T₃ were measured. Results: During an average follow-up of 14.5 months, teeth with denuded root lengths of 1-3 mm (n=12), 3-6 mm (n=11), and >6 mm (n=2) achieved root coverage of 97.01%±7.65%, 86.70%±5.66%, and 82.53%±1.39%, respectively. Miller classification I (n=12), II (n=10), and III (n=3) teeth showed mean coverage rates of 97.01%±7.65%, 86.91%±5.90%, and 83.19%±1.62%, respectively. At the donor sites, an average defect depth of 1.41 mm (70.5%) recovered in 3 weeks, and the wounds were epithelized completely in all cases. Conclusions: The modified tunneling technique in this study is a promising treatment modality for overcoming GR in the anterior mandible.

For histologic observation of the regenerated bone following guided tissue regeneration (GTR) using ePTFE membranes with calcium carbonate implant and autogenous bone graft, biopsies were collected from 2 patients during 5-year-postoperative surgical reentry. In both combined cases with guided tissue regeneration in conjunction with calcium carbonate implant and autogenous bone graft, significant bone fill and gain in probing attachment level was observed. In histologic examination, specimen in GTR case with calcium carbonate grafting was composed of a dense bone containing vascular channel with lamellar structure and viable bone cells in lacunae, however considerable calcium carbonate particles remained unresorbed and isolated from regenerated bone by the dense cellular and fibrous connective tissue. No formative cells could be seen in contact with remained calcium carbonate particles. In GTR case with autogenous bone grafting, specimen show was composed of a dense lamellar bone containing vascular channel, which showed normal alveolar bone architectures. The present observation indicate that guided tissue regeneration in conjunction with grafting, especially autogenous bone graft, has highly osteogenic potential, however resorbable calcium carbonate granules were not completely resorbed at 5 year postimplantation.

The recent trend of research and development on guided tissue regeneration focuses on the biodegradable membranes, which eliminate the need for subsequent surgical removal. They have demonstrated significant and equivalent clinical improvements to the ePTFE membranes. This study evaluate guided tissue regeneration wound healing in surgically induced intrabony periodontal defects following surgical treatment with a synthetic biodegradable membranes, made from a copolymer of glycolide and lactide, in 8 beagle dogs. After full thickeness flap reflection, exposed buccal bone of maxillary and mandibular canine and premolar was removed surgically mesiodistally and occlusoapically at $6mm{\times}6mm$ in size for preparation of periodontal defects. In experimental sites a customized barrier was formed and fitted to cover the defect. Flap was replaced slightly coronal to CEJ and sutured. Plaque control program was initiated and maintained until completion of the study. In 4, 8, 16 and 24 weeks after surgery, the animals were sacrificed and then undecalcified specimens were prepared for histologic evaluation. Histologic examination indicated significant periodontal regeneration characterized by new connective tissue attachment, cementum formation and bone formation. These membranes showed good biocompatibility throughout experiodontal period. The barriers had been completely resorbed with no apparent adverse effect on periodontal wound healing at 24 weeks. These results implicated that present synthetic biodegradable membrane facilitated guided tissue regeneration in periodontal defect.

The authors has observed the histopathologically and histochemically on the effect of the garlic and garlic oil to the liver and kidney of rats. In order to confirm the histochemical changes of the metabolism of polysaccarides, the periodic acid Schiff reaction was applied. The 30 albino adult male rats weighing about 150 grames from the National Institute of Health were housed individualy and devide into 3 experimental groups: Group C: stock diet group Group B: stock diet-garlic group Group A: stock diet-garlic oil group Group C was fed with stock diet only through out this experimental period, Group B was fed with stock diet supplemented with garlic homogenator to be 1%, and Group A was fed with stock diet supplemented with the garlic oil to 0.05%. The garlic oil used in this experiments was extracted by author. And all rats was fed during 10 weeks. The histopathological and histochemical results were shown in each figure. According to the all results, the following concIusions were drawn. 1) In the garlic oil administrated groups, congestion of the sinusoid was subsided and the liberation of the Kupffer's cells were observed. 2) In garlic administrated groups, fatty metamorphosis in hepatic cells, and slight liberation of Kupffer's cells in sinusoidal walls were observed. Connective tissue proliferation and collagen bundle were observed. 3) The connective tissue and blood vessel wall in portal area Were reacted intensely with PAS stain. The hepatic cells Were reacted intensely with PAS stain in control group and moderately or slightly in garlic and garlic oil administrated group. 4) There were no significant differences in collecting and Henle's loops in each groups, but narrowing of lumen of the distal tubules were observed in garlic oil administrated group. 5) The basement membrane of the tubules and the connective tissues of the vessel wall in Kideny were reacted intensely with PAS stain in each groups. In control and garlic administrated groups. the brush border of the proximal tubules were reacted intensely with PAS stain, but epithelium of the Heine's loop, proximal, distal and collecting tubules were reacted moderately. In garlic oil administrated-group, there were tendency of decreasing of PAS stain in each tubules.

Background: The term "overlap syndromes" designates a group of diseases in which polymyositis (PM) or dermatomyositis (DM) is associated with some other disorders of connective tissues. The aim of this study was to delineate the clinical features, laboratory findings, and outcome of treatment of "overlap syndromes" Methods: We analyzed the medical records of 16 patients (PM in 10, DM in 6) with well documented "overlap syndromes" between 1997 and 2004. The diagnosis was made when the criteria for two different disorders were fulfilled. Results: All patients were female. Age of onset ranged from 14 to 52 years (mean 29.8 years) with peak incidence in the third and fourth decades. Systemic lupus erythematosus (SLE) was associated in 10, systemic sclerosis in 7, and rheumatoid arthritis in 3 patients. Four of the patients had two different connective tissue diseases simultaneously. The characteristic clinical features were muscle weakness, arthralgia, Raynaud's phenomenon, and myalgia. In laboratory tests, creatine kinase (CK), lactic dehydrogenase (LDH), and transaminases were usually abnormal. Positive antinuclear antibody (ANA), rheumatoid factor (RF), and cryoglobulin were found in 100%, 69%, and 67% of the patients, respectively. Needle electromyography (EMG) showed abnormal findings compatible with myopathy in 15 patients. The pathology of muscle biopsy from 14 patients revealed findings compatible with inflammatory myopathy. Glucocorticoids were administered to 15 patients. The muscle strength improved in all the treated patients, which was well correlated with repeat CK level and EMG findings. Conclusions: The presence of autoantibodies such as ANA, RF, and cryoglobulin in patients with PM or DM highly suggests the possibility of an overlap syndromes. These syndromes reveal a strong female predominance. The myositis associated with them usually shows a good response to glucocorticoids treatment.
