Investigation on the characteristics of actomyosin was prepared from leg and breast muscle of duck treated by hard scalding and subscalding method and their extractability , ATPase activity , solubility and SDS polyacrylamide gel electrophoresis were compared. The extractability of actomyosin in leg and breast muscle of duck by hard scalding was 7.84 and 39.84mg/g, whereas 4.79 and 28.04mg/g by subscalding respectively. Ca-ATPase activity of breast muscle wash higher than that of leg muscle. In case of leg muscle, hard scalding was higher tan subscalding. Breast muscle showed that subscalding was higher than hard scalding in less than ionic strength 0.08, and was lower than hard scalding in over ionic strength 0.08.Mg-ATPase was great in ionic strength and subcalding was relatively higher than hard scalding. Without regard to be treated method and part, the start point and end point of solubility were like. Hard scalded muscle and breast muscle showed that proteins in thin filament produced many extraction.

To evaluate the effects of pulsed electric field (PEF) application on scalder and chiller water on Campylobacter contamination, four different treatments under three different water conditions including hard scalder water ($55^{\circ}C$), soft scalder water ($45^{\circ}C$) and chiller water, were applied as follows: i) a control treatment with no salt and no electric treatment, ii) a PEF only treatment, iii) a PEF treatment with 0.5% salt water, and iv) a PEF treatment with 1% salt water treatment. The use of PEF in hard scalding water showed an effect of reducing Campylobacter when compared to the control during the 200 s timeframe. With the addition of salt, the intervention caused at least 5.81 log CFU/ml reduction of Campylobacter counts after 200 s of PEF exposure. Similar effects were observed under soft scalding conditions. Campylobacter reductions were evident under chilling conditions with up to 2.00 log for PEF only, 5.77 log for PEF+0.5% salt and 2.69 log for PEF+1% salt treatment in water. Therefore, the current PEF setting for the scalder and chiller water can be successfully used to reduce pathogenic loads of Campylobacter on broiler chicken carcasses, and further research may be necessary to apply it in the poultry processing industry.

Purpose: Heterotopic calcification is the abnormal deposition of calcium salts in tissues other than bone and enamel, and it occurs in the form of dystrophic calcification or metastatic calcification. This deposition can occur under many conditions, but in some rare cases, it may develop in burns and nonhealed scars. It is difficult to treat the combination of heterotopic calcification and ulceration in scar tissues by using conservative therapy and to determine the margin of excision in such cases. Our study proposes the use of intraoperative C-arm-guided mapping of lesions with heterotopic calcification, and adequate excision of ulcers in chronic scars where heterotopic calcification is also observed. Methods: This study included 2 patients and was conducted from January 2010 to July 2010. The first patient was a 63-year-old woman who presented with atypical calcium deposits and chronic ulceration in the lower one-third region of the right leg. The second patient was a 38-year-old man who presented with a nonhealing ulcer that had developed on the right leg 3 months earlier he had a history of 40% scalding burns on the entire body. Surgery is the most reliable method for treating heterotopic calcification therefore, both patients were treated using intraoperative C-arm-guided marginal mapping of heterotopic calcification, followed by release of contracture, and eventually split-thickness skin grafting. Results: Plain radiographs of the leg showed spotty radiopaque areas in the hard part of the scar well superficial to the underlying bones. Histopathological analysis revealed multiple foci of calcified deposits, increased fibrosis, and inflammation in the scar tissue. Surgery-related complications were not observed. Conclusion: C-arm guided excision of calcified scars and the release of contracture can cure nonhealing ulcers and may therefore prevent recalcification.
