  • This study was carried out to compare the changes in the extractability, biological activity, and solubility of myofibrillar proteins and actomyosins during storage period at 4$^{\circ}C$ and -20$^{\circ}C$in pectoral. and leg muscle of broiler meat. 1. The results obtained are as fellows ; The extractabilities of myofibrillar proteins in pectoral and leg muscle were increased gradually to 7-days during storage at 4$^{\circ}C$ and decreased slightly during frozen storage at -20$^{\circ}C$. The extractabilities of actomyosins in pectoral and legmuscle were not greatly changed during cold storage and decreased gradually during frozen storage. 2. The Ca$\^$2+/-ATP ase activities of myofibrillar proteins in the both muscles were not greatly changed to 7-days during cold storage, and in the case of frozen storage, those were highest on the 2nd week, thereafter decreased with storage period. The Ca$\^$2+/-ATPase activities of actomyosins in pectoral and leg muscle were decreased sightly only frist day during cold storage and decreased gently during frozen storage. 3. Myofibrillar proteins in the both muscles were solubilized completely at 0.20M KCl in fresh meat, at 0.25M (pectoral) and 0.30M KCl (leg) in the cold storage, and at 0.30M KCl in the frozen storage. Actomyosins of both muscles were solubilized completely at 0.40M KCl in fresh meat, cold and frozen storage.

  • In order to investigate the effect of dietary fatty acids on lipids metabolism in adipose pads and superficial pectoral muscle of chicks, the present, experiment was carried out using signle comb White Leghorn male chicks fed a fat-free diet and diets containing margaric, stearic or linoleic acids. Total lipids of tissues were extracted with a chlorofrom-methanol solution. The lipid components were fractionated by thin layer chromatography and the fatty acid distribution of lipid fractions was determined by gas liquid chromatography. The neck adipose pads contained 34-62% total lipids, in which triglycerides, were dominant, being 97-98%. Margaric, stearic and linoleic acids were distributed at a relatively high rate in the adipose tissue when the corresponding acids were fed, and margaric acid feeding lowered palmitoleic acid distribution and linoleic acid feeding elevated stearic acid distribution. The wet superficial pectoral muscle contained 1.3-1.7% total lipids, of which 77-79% was phospholipids and 11-13% was free cholesterol. When margaric acid was fed, margaric and heptadecenoic acids appeared in the muscle lipids. When linoleic acid was fed, this acid was significantly highly distributed in every muscle lipid fractions, whereas, when stearic acid fed no elevation of stearic acid distribution was observed. In the muscle phospholipids, oleic acid was significantly highly distributed in the stearic acid fed chicks, and the linoleic acid feeding signigicantly lowered the distribution value of palmitic and oleic acids, but elevated the distribution value of stearic acid. And the linoleic acid feeding lowered the distribution value of eicosatrienoic acid and elevated the distribution value of arachidonic acid.

  • To investigate the effect of mercuric chloride on the pectoral muscel cells during chick embryogensis, chicken embryos were treated with mercuric chloride. Monoclonal antibodies against myosin were prepared for the localization of differentiation of thick filaments detected by the use of protein A-gold complex as a cytochemical marker. The effect of mercuric chloride was appeared not only to be ascribed with the reduced formation of myofibrilogenesis but also associated with induced change of morphology by the inhibition of protein synthesis.

  • Traumatic brachial plexus injuries can be devastating, causing partial to total denervation of the muscles of the upper extremities. Surgical reconstruction can restore motor and/or sensory function following nerve injuries. Direct nerve-to-nerve transfers can provide a closer nerve source to the target muscle, thereby enhancing the quality and rate of recovery. Restoration of elbow flexion is the primary goal for patients with brachial plexus injuries. A 4-year-old right-hand-dominant male sustained a fracture of the left scapula in a car accident. He was treated conservatively. After the accident, he presented with motor weakness of the left upper extremity. Shoulder abduction was grade 3 and elbow flexor was grade 0. Hand function was intact. Nerve conduction studies and an electromyogram were performed, which revealed left lateral and posterior cord brachial plexopathy with axonotmesis. He was admitted to Rehabilitation Medicine and treated. However, marked neurological dysfunction in the left upper extremity was still observed. Six months after trauma, under general anesthesia with the patient in the supine position, the brachial plexus was explored through infraclavicular and supraclavicular incisions. Each terminal branch was confirmed by electrophysiology. Avulsion of the C5 roots and absence of usable stump proximally were confirmed intraoperatively. Under a microscope, neurotization from the musculocutaneous nerve to two medial pectoral nerves was performed with nylon 8-0. Physical treatment and electrostimulation started 2 weeks postoperatively. At a 3-month postoperative visit, evidence of reinnervation of the elbow flexors was observed. At his last follow-up, 2 years following trauma, the patient had recovered Medical Research Council (MRC) grade 4+ elbow flexors. We propose that neurotization from medial pectoral nerves to musculocutaneous nerve can be used successfully to restore elbow flexion in patients with brachial plexus injuries.

  • Objective: This study was investigated the effects of dietary supplementation of Antrodia cinnamomea fermented product on modulation of antioxidation, anti-inflammation, and lipid metabolism in broilers. Methods: Functional compounds and in vitro antioxidant capacity were detected in wheat bran (WB) solid-state fermented by Antrodia cinnamomea for 16 days (FAC). In animal experiment, 400 d-old broiler chickens were allotted into 5 groups fed control diet, and control diet replaced with 5% WB, 10% WB, 5% FAC, and 10% FAC respectively. Growth performance, intestinal microflora, serum antioxidant enzymes and fatty acid profiles in pectoral superficial muscle were measured. Results: Pretreatment with hot water extracted fermented product significantly reduced chicken peripheral blood mononuclear cells death induced by lipopolysaccharide and 2,2'-Azobis(2-amidinopropane) dihydrochloride. Birds received 5% and 10% FAC had higher weight gain than WB groups. Cecal coliform and lactic acid bacteria were diminished and increased respectively while diet replaced with FAC. For FAC supplemented groups, superoxide dismutase (SOD) activity increased at 35 days only, with catalase elevated at 21 and 35 day. Regarding serum lipid parameters, 10% FAC replacement significantly reduced triglyceride and low-density lipoprotein level in chickens. For fatty acid composition in pectoral superficial muscle of 35-d-old chickens, 5% and 10% FAC inclusion had birds with significantly lower saturated fatty acids as compared with 10% WB group. Birds on the 5% FAC diet had a higher degree of unsaturation, followed by 10% FAC, control, 5% WB, and 10% WB. Conclusion: In conclusion, desirable intestinal microflora in chickens obtaining FAC may be attributed to the functional metabolites detected in final fermented product. Moreover, antioxidant effects observed in FAC were plausibly exerted in terms of improved antioxidant enzymes activities, increased unsaturated degree of fatty acids in chicken muscle and better weight gain in FAC inclusion groups, indicating that FAC possesses promising favorable mechanisms worthy to be developed.
