Comparison of plasma metabolite concentrations and enzyme activities in beef cattle raised by different feeding systems in Korea, Japan and New Zealand

Concentrations of metabolites and immunoreactive insulin (IRI) and activities of enzymes related to energy metabolism were measured in plasma of Korean and Japanese beef cattle, which were raised by the indoor feeding system programmed to feed larger amount of roughage in their growing periods and larger amount of concentrate diet in their finishing periods (Japanese feeding system), and grazing New Zealand beef cattle. By the Japanese beef grading system, Korean and Japanese beef cattle showed high beef quality score, average grade 3.3 and 3.6, respectively. The plasma free fatty acid and lactate concentrations and lactate dehydrogenase (LDH), malate dehydrogenase (MDH) and aspartate aminotransferase (AST) activities in Korean beef cattle were significantly higher than those in Japanese beef cattle. The plasma lactate concentration in Korean beef cattle was 8.40 mmol/l, which was similar to the values observed in lactic acidosis. The higher activities of plasma LDH, MDH and AST may indicate slight liver damage by slightly acidotic conditions in Korean beef cattle. New Zealand beef cattle fed on pasture which they harvest by grazing showed significantly lower plasma glucose, cholesterol, lactate and IRI concentrations and enzyme activities than those in Korean and Japanese beef cattle fed on larger amount of concentrate diets. Plasma metabolite concentrations and energy metabolism-related enzyme activities may be good indicators for evaluating metabolic conditions of beef cattle raised by different feeding systems.     

Activities of Enzymes in the Malate–Aspartate Shuttle in the Peripheral Leukocytes of Dogs and Cats

The activities of the enzymes involved in the malate–aspartate shuttle and the expression of malate dehydrogenase (MDH), a rate-limiting enzyme in the NADH shuttle that produces ATP in glucose metabolism in leukocytes, were determined to investigate the differences in this shuttle system in the peripheral leukocytes of dogs and cats. There were no significant differences between dogs and cats in plasma glucose, immunoreactive insulin, free fatty acid or triglyceride concentrations. The activities of cytosolic and mitochondrial MDH and of mitochondrial glutamate dehydrogenase (GLDH) in canine leukocytes were significantly higher than in feline leukocytes. High activities of MDH in canine leukocytes were confirmed by RT-PCR analysis on the total RNA extracted from leukocytes. It was concluded that there were significant differences between dogs and cats in the NADH shuttle system.     

PEG胁迫对燕麦苗期保护酶的影响

 用不同质量分数的PEG-6000对3个品种燕麦幼苗进行干旱胁迫,测定了胁迫后1~5 d内其叶片的超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性变化,研究干旱胁迫对燕麦保护酶活性的影响。结果表明,在不同质量分数PEG 6000胁迫下,SOD、POD和CAT活性随时间延长呈先升高后降低的趋势;低胁迫水平SOD、POD和CAT活性增加值大于高胁迫水平,受胁迫植株的保护酶系统能够进行自身的调节以抵抗干旱伤害。

Lipid peroxides and antioxidants in serum of neonatal calves

OBJECTIVE: To examine the association between oxidative stress and antioxidants in neonatal calves after birth. SAMPLE POPULATION: Sera from 6 healthy Holstein-Friesian cows and 7 of their newborn calves were obtained at various intervals after birth. PROCEDURE: Lipid peroxides in serum of cows and their newborn calves were estimated by measuring concentrations of thiobarbituric acid-reactive substances (TBARS). The antioxidative activities of neonatal sera were evaluated by measuring their superoxide-scavenging activities, ferroxidase activities, and the concentration of bilirubin-associated albumin. RESULTS: Concentration of TBARS in neonatal sera within 1 day after birth was significantly higher than concentrations > or = 2 days after birth and concentrations in serum of the dams. In contrast, antioxidative activities of neonatal sera, evaluated on the basis of superoxide-scavenging activities, ferroxidase activities, and concentration of bilirubin-associated albumin 3 hours after birth, were significantly lower than antioxidative activities in sera of the dams. CONCLUSIONS: Susceptibility of calves to oxidative stress during the neonatal period may be explained by the immature defense system against superoxide radicals.     

Technical note: a rapid method for quantification of calpain and calpastatin activities in muscle

Stepwise and continuous gradient ion-exchange chromatography were compared for yield of calpains and calpastatin from ovine muscle in a study designed to quantify their activities for comparative purposes. In Exp. 1, a continuous (25 to 400 mM NaCl) gradient and a two-step gradient method (200 mM NaCl to coelute mu-calpain and calpastatin together and then 400 mM NaCl to elute mu-calpain) were compared. For the two-step method, mu-calpain activities were determined by subtracting calpastatin activities before and after heat inactivation of mu-calpain. Both the two-step and the continuous gradient method yielded similar results over a broad range of activities. The stepwise gradient method does not require the use of fraction collectors and pumps, and it can be completed in a fraction of the time required for the continuous gradient method. In Exp. 2, the two-step method was compared with a three-step method (100 mM NaCl to elute calpastatin, then 200 mM NaCl to elute mu-calpain, and then 400 mM NaCl to elute m-calpain). Unlike the continuous gradient method, calpastatin and mu-calpain could not be completely separated using the three-step chromatography method. Thus, the three-step gradient method should not be used to quantify the components of the calpain proteolytic system. The present results indicate that the two-step gradient method is a fast and inexpensive method to determine calpain and calpastatin activities in studies designed to quantify the components of the calpain proteolytic system in skeletal muscle.
