  • Pacemaker lead-related infective endocarditis is an uncommon, but serious complication. We report a case of a 45-year-old man who had symptom of intermittent high fever and rupture of sinus Valsalva that developed after a redo aortic valve replacement and transvenous permanent pacemaker implantation. Positive blood cultures of streptococcus viridans and transesophageal echocardiography showing a large mobile vegetation on pacemaker lead and tricuspid valve lead to the diagnosis of pacemaker lead-related infective endocarditis. Initial antibiotic therapy followed by surgical extraction of the pacemaker lead and wide debridement of infective tissues including multiple vegetations was required. Postoperative antibiotic therapy was continued for 4 weeks. The postoperative course has been uneventful. The patient is totally asymptomatic and is doing well up to now.

  • The purpose of this study was to investigate the quality characteristics of Garaedduk with regard to the amount of added whole soybean curd (Chun-Tofu). Whole soybean curd was added in amounts of 0, 3, 6 and 9%. Whole soybean curd Topokki dduk was stored at room temperature for 48 hours. The moisture contents had no significant difference for increases in the amount of whole soybean curd. The L value and b values of Garaedduk increased significantly with increases in the amount of whole soybean curd. Texture characteristics of Garaedduk measured with a texture analyzer revealed that hardness and cohesiveness decreased significantly for different amounts of whole soybean curd, and hardness increased significantly and cohesiveness and chewiness decreased with increase of storage time. As for sensory characteristics, samples with 9% added whole soybean curd rated higher in overall acceptability compared with other samples. In regard to cooking properties, water absorption increased and solid contents decreased with increases in the amount of whole soybean curd. Therefore, Garaedduk containing 9% whole soybean curd was most preferable.

  • This study was conducted to investigate the properties of noodle which was made of composite flour blended with the powder of synnemata of Beauveria bassiana. The characteristics of cooked-noodle including color, cooking properties, mechanical texture properties were measured, and sensory evaluation was performed. The L-value of dry and wet-noodle which made of composite flour was similar to that of 100% wheat flour, but a and b-value were higher than those of 100% wheat flour. There were no differences in the weight, volume and water absorption of the cooked-noodle made of composite flour and that of 100% wheat flour, but the turbidity of the cooked-noodle made of composite flour was higher than that of 100% wheat flour. The breaking force of dry-noodle which was made of composite flour was same as that of 100% wheat flour. Hardness and Gumminess of the cooked-noodle which was made of composite flour blended with synnemata powder at level of 1∼5% were same as those of 100% wheat flour. Springiness, chewiness, cohesiveness and adhesiveness of the cooked-noodle which was made of composite flour blended with synnemata powder at level of 1% were similar to those 100% wheat flour. The results of sensory evaluation showed that the cooked-noodles containing 1% and 3% synnemata powder were acceptable as much as those of 100% wheat flour in terms of color, taste, flavor, texture and overall acceptance.

  • The washed fresh ginsengs packed with air, vaccum and nitrogen gas were irradiated at the levels of 1,2 and 3kGy gamma radiation and then stored at $4{\sim}5^{\circ}C$ for 90days to investigate the effects of gamma radiation on microbial inactivation, eelworm disinfestation and physicochemical changes. After a 90 day storage, $2{\sim}3kGy$ irradiated groups showed 20% of weight loss and 10% of rot while non-irradiated group 100% and 20% or more, respectively. Also the irradiated groups showed somewhat lower values of specific gravity, color density and hardness immediately after irradiation, thereafter higher value of them with storage time than those of non-irradiated group. The irradiation increased the yields of ginseng extract and crude saponins but no effects on the proximate composition and TLC and HPLC patterns of saponin. The food-borne microorganisms decreased in viable cell counts by $2{\sim}3$ log cycles with $2{\sim}3kGy$ radiation and the eelworms were completely disinfested with 1 kGy radiation.

  • Gastrodia elata blume (GEB) is considered to be a useful herbal medicine in oriental countries for the treatment of headache, migraine, dizziness, childhood convulsion, epilepsy, rheumatism, hypertension, neuralgia and neurological disorders. This study was carried out to investigate the quality of bread added with the powder of GEB. The possibility of GEB wheat flour mixture as bread was studied by adding 0%, 0.5%, 1.0%, 1.5%, 2.0% of GEB powder to wheat flour. In Farinograph data, the dough stability decreased with the increase of GEB powder. Granular size of starches ranged from $36\;{\mu}m\;to\;60{\mu}m$, and the shape of them showed a long oval figure. Amylograph showed that the increase in the ratio of GEB on the doughs slightly elevated in the maximum viscosity. The loaf volume of 0.5% powder increased by 10.2% but that of 2.0% decreased by 16.8%. The moisture content was 43.57% in the control but it increased as the powder addition. The colors of crust and crumb were not significantly different among L, b and ${\Delta}E$, but 'a' value in crumb was increased as the powder addition. The addition of the powder had no significant effect on bread texture. In sensory evaluation, the moistness increased as the increase of the powder addition. The control bread was most excellent, and the bread made by mixing additives were better than just 0.5% GEB-wheat flour in terms of quality.

  • Prunus mume is rich in organic acid, and excels in antioxidant activity. However, development of processed foods using Prunus mume is very limited, and characteristics of its products are different according to the region they are processed in. In this study, we collected 13 kinds of sugar-preserved Prunus mume home-made products in Hadong, and investigated their physical and manufacturing characteristics to select a superior product. 5 kinds of sugar-preserved Prunus mume products were selected according to results of sensory evaluation, and the overall acceptability of product No.13 was superior. Moisture contents of the 5 samples ranged from 45.2~53.3%, and pH and acidity showed similar values at about 2.8 and 0.4%, respectively. Sugar content of product No.13 were slightly lower than other products. Crude protein and lipid contents were similar at about 0.4 and 0.5%, respectively. Hardness value of product No.13, selected by its texture in sensory evaluation, was higher than others. The main components of organic acids were oxalic, malic, citric and fumaric acid, and citric acid content occupied more than 60% of total organic acid content. Also, the main components of free sugar were glucose and fructose.

  • It has been recently reported that 2-bromopropane (2-BP) induces male reproductive toxicity in both human and experimental animals. However, delayed effects of 2-BP on male reproductive system have not been investigated in detail. The present study was conducted to investigate the testicular toxicity of 2-BP and to determine the recovery of normal spermatogenesis in Sprague-Dawley rats. Male rats aged 5 weeks were administered 1,000mg/kg 2-BP by gavage daily for 4 weeks and sacrificed sequentially at 1, 2, 3, 4 and 12 weeks after initiation of 2-BP treatment. Testicular toxicity was evaluated qualitatively by histopathological examinations and quantitatively by reproductive organ weights, spermatid head count, and repopulation index. In the 2-BP treated rats, the body weights was significantly suppressed and the weights of testes and epididymides were also decreased in a time-dependent manner. On histopathological examination, spermatogonia in stages I-VI and preleptotene and leptotene spermatocytes in stages VII-IX were strongly depleted at 1 week of dosing. Spermatogonia were depleted extensively in all spermatogenic stages at 2 weeks. Continuing with the evolution of spermatogenic cycle, zygotene spermatocytes, pachytene spermatocytes, and round spermatids were sequentially depleted at 2, 3, and 4 weeks of dosing due to the depletion of their precursor cells. Vacuolization of Sertoli cells and spermatid retention were also observed at all time points, suggesting that 2-BP induced Sertoli cell dysfunction. At 12 weeks, after 8 weeks recovery, most of the tubules appeared severely atrophic and were lined by Sertoli cells only. Leydig cell hyperplasia in the interstitial tissue was also found. In addition, dramatic reductions in the number of spermatid heads and repopulation index were observed, indicating that 2-BP-induced testicular injury is irreversible. These results indicate that 4 weeks repeated-dose of 1,000mg/kg 2-BP results in a progressive germ cell loss due to the depletion of spermatogonia followed by long-term testicular atrophy in SD rats.

  • Purpose: To determine the usefulness of limb salvage operation with recycled autogenous bone graft in musculoskeletal malignant tumors. Materials and Methods: Twenty nine cases, who underwent limb salvage operation with recycled autogenous bone graft for the treatment of musculoskeletal malignant tumor between February 1990 and January 2003, were included. There were 18 males and 11 females and the mean age was 33 years (range, 10 to 65 years). The mean follow-up period was 51.8 months (range, 18 to 117 months). The Enneking stage was IIA in 10 cases and IIB in 19 cases. The recycling method of autogenous bone was deep freezing in 6 cases, autoclaving in 11 cases, pasteurization in 7 cases and the composite of autoclaving and vascularized fibular graft in 5 cases. The union of junctional site was evaluated radiologically and the functional results was analyzed by the grading systems of the International Symposium On Limb Salvages (ISOLS). Results: The mean union time was 7.2 months (range, 3 to 15 months). The union took 5.8 months (range, 4 to 8 months) in deep freezing, 9.7 months (range, 6 to 15 months) in autoclaving, 5.9 months (range, 4 to 8 months) in pasteurization, and 5 months (range, 4 to 8 months) in the composite of autoclaving and vascularized fibular graft. The mean functional evaluation percentage was 76.8% (range, 40 to 90%). It was 65.8% (range, 40 to 85%) in deep freezing, 76.6% (range, 40 to 90%) in autoclaving, 81.6% (range, 70 to 90%) in pasteurization, and 83.4% (range, 75 to 90%) in the composite of autoclaving and vascularized fibular graft. There were 6 cases of complications including 1 case of local recurrence, lung metastasis, infection, fracture, respectively and 2 cases of nonunion. Conclusion: The limb salvage operation with recycled autogenous bone graft is a useful treatment method for the musculoskeletal malignant tumors. Particularly, autoclaving is the most reliable sterilization method. The vascularized fibular graft can compensate decreased osteoinductivity and mechanical strength of recycled bone. So, the composite of autoclaving and vascularized bone graft seems to be a favorable treatment method for high grade malignant musculoskeletal tumors.

  • The quality characteristics and antioxidant activities were evaluated for jams containing fructooligosaccharide (FTO) and FTOS (sucrose 50%+FTO 50%) substituted for sucrose. The endpoint of jam preparation was determined to be sweetness of $64^{\circ}Brix$. Moisture contents differed among the treatments, whereas acidity did not. Reducing sugar content and viscosity were highest in the FTO (0.144%, 126,800 cP), and the lowest in control (0.074%, 101,600 cP). Lightness (L value), redness (a value), and yellowness (b value) values of the Hunter color system were highest in the FTO sample. Hardness and springiness of textural properties were the highest in the FTO sample as well. Antioxidant activities were the highest in the FTO sample with the lowest $IC_50$ values (42.3 mg/g for DPPH and 22.4 mg/g for hydroxyl radical scavenging activities). Total phenolic content was the highest in the FTO sample among all treatments. The overall acceptance score of black garlic jam containing FTO was the highest. Based on these results, it is suggested that FTO was appropriate for achieving good qualities such as antioxidative activity in black garlic jam.

  • Background: This study was designed to evaluate the efficacy of a mixture of hyaluronic acid and sodium carboxymethyl cellulose ($Guardix-sol^{(R)}$) on experimental pericardial adhesion. Material and Method: Thirty rats were divided into 2 groups of 15 rats each and pericardial mesothelial injury was induced during surgery by abrasion. In the control group, blood and normal saline were administered into pericardium; in the test group, blood and HA-CMC solution were administered. Pericardial adhesions were evaluated at 2 weeks (n=5), 4 weeks (n=5), and 6 weeks (n=5) after surgery. The severity of adhesions was graded by macroscopic examination, and the adhesion tissue thickness was analyzed microscopically with Masson trichrome stain and an image processing program. Result: The test group had significantly lower macroscopic adhesion scores ($2.9{\pm}0.6$ : $3.9{\pm}0.4$, p<0.000) compared with the control group. For microscopic adhesion tissue thickness, the test group had lower scores compared with the control group, but this difference was not statistically significant ($91.73{\pm}49.91$ : $117.67{\pm}46.4$, p=0.106). Conclusion: We conclude that an HA-CMC solution ($Guardix-sol^{(R)}$) reduces the formation of pericardial adhesions in this animal model.
