  • Purpose: Microfat graft is a common procedure for correcting tear trough deformity and dark circle. Because the tissue in this area is very thin, the grafted fat, sometimes, induces palpable lumps and uneven skin contour. When it happens, the surgical removal of the grafted fat is often needed. The authors made attempt of transconjunctival approach for removal, and this made infraorbital fat repositioning possible at the same time. Methods: 15 female patients with history of microfat graft on lower eyelid, got operation for the grafted fat removal with transconjunctival approach from April of 2009 to July of 2010. The dissection was performed in accordance with infraorbital fat repositioning surgery. Through the transconjunctival incision, knotted fat on orbital septum and orbicularis oculi muscle was removed without damage on skin. After grafted fat removal, subperiosteal space was made 1~2 mm below the inferior orbital rim by elevating periosteum. With preserving orbital septum, infraorbital fat was repositioned and anchored to subperiosteal space. Finally, transconjunctival incision was closed with absorbable suture material. Results: 14 patients in the study showed satisfactory results. The problems like uneven skin contour and knotted fat mass, were all solved. In only one patient, incomplete correction was observed, as bulging on her right lower eyelid still remained. One patient complained of transient numbness on lower eyelid, but there was no specific complication other than this. Conclusion: The authors attempted the method of transconjunctival approach to remove former grafted fat in lower eyelid and reposition infraorbital fat simultaneously. Since the study brought great results, the method would be helpful to patients and surgeons.

  • The objective of this study was to investigate the effects of different concentrations of WSP (wheat sprout powder) and ISP (isolated soy protein) on the quality of breakfast sausage. Treatments were formulated as follows: Control, T1 (2.0% ISP), T2 (1.5% ISP + 0.5% WSP), T3 (1.0% ISP + 1.0% WSP), T4 (0.5% ISP + 1.5% WSP) and T5 (2.0% WSP). The treatments were analyzed for color, pH, cooking loss, emulsion stability, protein solubility, viscosity, texture properties and sensory evaluation. Lightness and redness were reduced and yellowness was increased as increased level of WSP, due to the dark green color of WSP (p<0.05). The pH values of all samples were affected by WSP which has lower pH (p<0.05). The emulsion stability and cooking loss of treatments were improved with increasing level of WSP (p<0.05). The protein solubility, viscosity and overall texture properties of the sausage indicated significant differences in relation to the level of WSP and ISP (p<0.05). The sensory evaluation indicated that the greatest flavor and overall acceptability in sausage was achieved at WSP 1% combination with ISP 1% (T3) (p<0.05). Therefore, these results indicate that breakfast sausage containing 1% WSP and 1% ISP is the optimal formulation, taking into consideration the overall physico-chemical properties and sensory evaluation.

  • Bronchogenic cysts are generally presented as a well defined mass that have thin and smooth wall in the intrapulmonary or mediastinal area by simple chest radiographs. We present the case of a 20-year-old man with a ill-defined left upper lobe mass, found by chest radiographs. At the preoperative examinations, chest computed tomography showed ill-defined mass with Hounsfield Number 26, and nonspecific findings were shown by the bronchoscopy and percutaneous needle aspiration. The patient was undertaken the left upper lobectomy. The surgical specimen contained a ill-defined mass, measuring $2{\times}3$ cm. On the section of the mass, a cyst containing dark brown thick materials was noted. The cyst was unilocular, and the wall showed a trabeculation. Microscopically, the cystic mass was lined with ciliated pseudostratified columnar epitheliums and surrounded by smooth muscle and cartilage.

  • Shucking(removing the meat from the shell) an oyster requires that the muscle attachments to the two shell valves and the hinge be severed. Described here is the computer vision software needed to locate the oyster hinge line so it can be automatically severed, one step in development of an automated oyster shucker. Oysters are first prepared by washing and trimming off a small shell piece on the oyster hinge end to provide access to the outer hinge surface. A computer vision system employing a color video comera then gabs an image of the hinge end of the oyster shell. This image is Processed by the computer using software. The software is a combination of commercially available and custom written routines that locate the oyster hinge. The software uses four feature variables, circularity, rectangularity, aspect-ration, and Euclidian distance, to distinguish the hinge object from other dark colored objects on the hinge end of the oyster. Several techniques, including shrink-expand, thresholding, and others, were used to secure an image that could be reliably and efficiently processed to locate the oyster hinge line.

  • This study was carried out to investigate the optimal conditions for meat paste production with sardine. To improve the gel forming ability of meat paste, washing time and condition with alkaline solution, setting time and temperature, and heating temperature before pasteurization were controlled, and the influences of the freshness of raw sardine and the mixing ratios of ordinary and dark muscles on the duality of the meat paste product were discussed. The frozen storage showed a predominant effect on keeping freshness of raw sardine at different storage conditions and gel forming ability was maintained for 1 day at ice storage, for 3 days at $-3^{\circ}C$ and for 4 days at frozen condition, but there was no effect on keeping freshness of raw sardine in the storage at $25^{\circ}C$. Gel strength of meat paste product tended to decrease with washing time of raw meat, and in case of washing 3 times the meat appeared excellent in gel strength, but in case of seven and nine times the meat showed lower water holding capacity and decreased organoleptic test score in the quality of meat paste prtoduct. Raw meat washed with alkaline solution showed a desirable effect on gel forming ability compared with that washed with tap water, and in the case of washed with $0.5\%$ sodium bicarbonate solution exhibited the most favorable effect on gel forming. The gel strength of the meat paste product decreased with the increase of mixing ratios of dark muscle in the raw meat. Setting time and temperature for the gel forming ability of meat paste were good at $5^{\circ}C$ for 20 hours and at $20^{\circ}C$ for 2 hours. In the heating temperature of meat paste, heating treatment at $90^{\circ}C$ was desirable for gel forming.

  • Sardine and mackerel so called dark muscled fish have been underutilized due to the disadvantages in bloody meat color, high content of fat, and postmortem instability of protein. Recent efforts were made to overcome these defects and develope new types of product such as texturized protein concentrates and dark muscle eliminated minced fish. Approach of this study is based on the rapid dehydration of foamed fish-starch paste by dielectric heating. In process comminuted sardine meat was washed more than three times by soaking and decanting in chilled water and finally centrifuged. The meat was ground in a stone mortar added Ivith adequate amounts of salt, foaming agent, and other ingredients for aid to elasticity and foam stability. The ground meat paste was extruded in finger shape and heated in a microwave oven to give foamed, expanded, and porous solid structure by dehydration. Dielectric onstant $(\varepsilon')$ and dielect.ic loss $(\varepsilon")$ values of sardine meat paste were influenced by wavelength and moisture level. Those values at 100 KHz and 15 MHz were ranged 2.25-9.86; 2.22-4,18 for E' and 0.24-19.24; 0.16-1.20 for E", respectively, at the moisture levels of $4.2-13.8\%$. For a formula for fish-starch paste preparation, addition of $20-30\%$ starch (potato starch) to the weight of fish meat, $2-4\%$ salt, and $5-10\%$ soybean protein was adequate to yield 4-5 folds of expansion in volume when heated. Addition of e99 yolk was of benefit to micronize foam size and better crispness. In order to provide better foaming and dehydration, addition of $0.2-0.5\%$sodium bicarbonate, foaming agent, was proper to result in foam size of 0.5-0.7 mm and foam density of $200-400\;/cm^2$ which gave a good crispness. Heating time was depended upon the moisture level of fish-starch paste. For a finger shaped paste (1.0cm. $D\times10cm.L$) heating for 150-200 sec. in a microwave oven (700W. 2.45GHz) was sufficient to generate foams, expand, and solidify the porous structure of fish-starch paste. When the moisture content was above $55\%$ browning and scorching was deepened due to over-expansion and over-heating whereas the crispness was hardened by insufficient expansion at lower moisture content. In quality evaluation of the product, chemical composition of $30\%$ starch and $3\%$ salt added product was moisture $8.8\%$, lipid $2.4\%$, carbohydrate $46.7\%$, protein $36.1\%$, and ash $6.0\%$. Eleven membered panel test evaluated that fish-starch paste was acceptable in color, crisp-ness, taste, except a trace of fishy odour which could be masked by the addition of spice extracts.

  • To obtain further information concerning the nature myofibrillar proteins in a food system, an investigation has been conducted to compare the change in the biochemical property of the myofibril with the changes in the morphological structure of the myofibril. When myofibrils were prepared with 0.16 M KCl-0.04 M Tris-HCl, the band pattern was clear and distinct. There was a uniform thickening of A-band, a sharp appearence of Z-lines and a wide I-band. The band pattern of myofibrils was changed as the composition of extraction solution was changed. Also the ATPase activity of myofibril changed as the length of sarcomere changed. When myofibrils were treated with a low concentration of trypsin, myofibrils turned in the contracted state. With the progress of prolonged trypsin treatment, most of myofibrils exhibited a pattern of alternating light and dark bands, supercontracted pattern. Although myofibrils exhibited a supercontracted band pattern, the ATPase activity of myofibril continued to increase with the progress of trypsin treatment. An assumption was made that tropomyosin may be located in Z-line and that troponin-tropomyosin complex can inhibit the ATPase activity of myofibrils through the structural alternation of myofibril.

  • To investigate the effect of postmortem phases on lamb meat quality, the physicochemical quality, microstructure and water mobility of oyster cut, short loin, knuckle and silverside muscles from Small-Tail Han sheep were evaluated in the pre-rigor, rigor mortis and post-rigor phases. Pre-rigor lamb meat had higher pH and water holding capacity (WHC), whereas lower CIE L*, b*, hue angle values than rigor mortis and post-rigor meat (p<0.05). The Warner-Bratzler shear force (WBSF) values were higher in rigor mortis short loin and silverside than their pre-rigor and post-rigor counterparts, pre-rigor short loin had lower WBSF value than its post-rigor counterpart (p<0.05). Muscle fibers shrank laterally and longitudinally during the onset of rigor mortis. Rigor mortis and postrigor lamb meat exhibited wide I-bands, dark A-bands, short sarcomeres and large inter-myofibrillar spaces. The shift of immobilized water to free water and repulsion from the intra-myofibrillar space to the extracellular space result in the increase of water loss in rigor mortis and post-rigor lamb meat. The results of the principal component analysis (PCA) indicated that rigor mortis and post-rigor lamb meat had similar quality properties but different from pre-rigor lamb meat. In conclusion, the lamb meat in the pre-rigor phase had good tenderness, color and WHC. The results of this research could provide some theoretical references for lamb meat production and processing.

  • A dehydrating sheet comprises polymeric water absorber. which are packed in a semipermeable cellophane film bag allowing selective permeation of water. This sheet dehydration is quite different from conventional drying method such as sun drying, hot-air blast drying and cold air blast drying in a sense that samples are dried without heat treatment. As a part of the studies to develope a new processing method for effective utilization of dark muscle fishes, the preparation of a good quality salted and semi-dried mackerel by the dehydrating sheet was attempted. The dehydration time for preparation of a salted and semi-dried mackerels containing approximately equal moisture content were revealed $180{\sim}510min$ in conventional drying method and $90{\sim}160min$ in this sheet dehydration, respectively. The moisture and histamine contents of those salted and semi-dried mackerels were $59.4{\sim}62.4%$ and $2.5{\sim}3.6 mg/100g$, respectively. The changes in peroxide value, fatty acid composition, brown pigment formation, myofibrillar protein solubility and Ca-ATPase activity during processing of the salted and semi-dried mackerel prepared by the sheet dehydration were more lower than those of products prepared by conventional drying methods. Therefore, these result showed that the quality of a salted and semi-dried mackerel prepared by the sheet dehydration was imperial to that of those products by conventional drying method.
