The purpose of this study was to investigate the properties of myofibril and myosin B. Samples were extracted from the longissimus dorsi of lumber vertebra from the porcine weighing over 110kg in live weight. The porcine muscle was held either at 0℃ or at 40 ℃ for 30, 60, and 90 min. The carcass temperature immediatly after slaughter ranged from 42.0℃ to 42.6℃ with the line weight. The samples held at 40℃ showed much less contractility than those treated at 0℃. No contractility reaction was found on those treated for 90 min at 40℃. Extractibility of myosin B from the sample treated at 40℃ was lower than those treated at 0℃ The myofibril was not found in the residue of the sample treated at 0℃ which myosin B was extracted from treated at O℃ But there was much more myofibril in the residue from those treated for 60 min and 90 min at 40℃. Thus, the difference found in this experiment seemed at to reflect the differences in biological activities of the myofibrillar protein. As they corresponded to PSE porcine muscle symptoms, it can be concluded that the porcine carcass has to be held at 0℃immediately after slaughter in order to produce good quality pork especially from the animals exceeding 110kg in live weight.

N/A Background/Aims: Most of Ihe chronic liver diseases of variable etiologies are accompanied by a pathobiochemical reaction So-called fibrosis. Liver fibrosis was recently recognized as all the complexity of dynamic changes of the hepatic extracellular matrix(ECM). And ECM consists of four major components: collagen, glycoprotein such as fibronectin and laminin, proteoglycan, and elastin. Among these, collagen I and III are the representatives of disproportion of synthesis and degradation in conjunction with fibrogenesis. To elucidate the clinical significance of procollagen propeptide I(PICP) and III(PIIINP) measurements among the sera out of patients with chronic liver diseases, radioimmunoassay 4vas employed in this investigation. Methods: Sera tested were obtained from pathologically-proven 54 patients; 4 cases of fatty liver, 11 cases of chronic persistent hepatitis, 13 cases df chronic active hepatitis, 15 cases of liver cirrhosis and 11 cases of hepatocellular carcinoma. All:the patients except 4 cases of fatty liver were shown positivity of HBsAg. PICP and PIIINP radioimmunoassay kits(Farmos Diagnostica, Oulunsalo, Finland)were purchased for this study. ResOlts: PICP concentration (mean+standard error) was highest in liver cirrhosis (280.06>39,83 pg/L). PICP in liver cirrhosis was significantly elevated in cornparison to that (109.30+14.58) in fatty:liver(p=0.045), that (122.22>10.26) in chronic persistent hepatitis (p=0.003), and that (158.59>21.58) in chronic active hepatitis(p=0.016), PICP in hepatocellular carcinoma was decreased to 1'94.05+ 29.89. Similarly, PIIINP concentration revealed highest level in liver cirrhosis(17.29+3.58 pg/L). This value was significantly higher than that of chronic persistent hepatitis(5.12+0.59)(p=0.008). Contrarily to these results, concentration ratio of PICP/PIIINP was high in fatty liver (29.27>6.29) and chronic persistent hepatitis (25.04+2.00), These value were statistically higher than that of chronic active hepatitis (17.632.67) (p=0.043). PICP/PIIINP ratio in liver cirrhosis (21.58+3.29) showed no statistical difference. Conclusions: On the basis of these data, it is suggested that the elevation of PICP and PIIINP in the sera of the patients with chronic liver diseases means emerging the liver cirrhosis. And the ratio of these markers can be helpful in differential diagnosis of chronic liver diseases. (Korean J Gastroenterol 1996; 28:815-823)
돈골격근의 생화학적 특성에 관한 연구 2 . 환경온도가 Myosin B 의 생물학적 기능에 미치는 영향

Samples were taken from the porcine longissimus dorsi of lumbar vertebra of the animals weighing over 110 kg of live weight. Samples were treated at 0℃ or for 30, 60. and 90 min at 40℃. Superprecipitation activity of myosin B from the samples at 40℃ was much lower than those at 0℃. No superprecipitation was found in the case of myosin B of those treated for 90 min at 40℃. Also ATP sensitivity of myosin B of the samples treated at 40℃, was lower than those at 0℃. In 40℃ treatment. small amount of M. H. C. was founded and α-actinin degradation. Thus, the differences found in this experiment seem to reflect the differences in biological function of the myosin B. As they correspond to PSE porcine muscle symptoms. it is Concluded that the porcine carcass has to be treated at 0℃ immediately after slaughter for production of good quality of porcine meat especially for the animals slaughtering at the live weight exceeding 110 kg.
