红富士苹果套纸膜复合袋技术试验总结

苹果套纸袋、塑膜袋技术在农村得到了大面积推广应用，果农们获得了明显的经济效益。但生产中应用的果袋种类多，使用效果、经济效益反映不一，存在着许多问题。自2002年以来，“新惠阳”纸膜袋，一种新型袋被应用于生产中，苹果褪绿快，果面光洁细腻，脱袋后着色迅速。“新惠阳”纸膜袋成本低，套出的果实售价高，增值明显，经济效益相对较高，生产上值得大力推广应用。     

转型时期的中国社会保障制度

近年来,我国的社会保障制度改革虽取得了一些突破性进展,但面临的形势仍十分严峻。社会保障问题引起人们的普遍关注。应建立什么样的筹资模式,社会保障的城乡整合,农民工人的保障,社会保障资金的管理等都是人们讨论的热点。本文对转型时期的中国社会保障问题进行了初步研究。

Pharmacokinetic/pharmacodynamic relationship of marbofloxacin against Pasteurella multocida in a tissue‐cage model in yellow cattle

The fluoroquinolone antimicrobial drug marbofloxacin was administered to yellow cattle intravenously and intramuscularly at a dose of 2 mg/kg of body weight in a two‐period crossover study. The pharmacokinetic properties of marbofloxacin in serum, inflamed tissue‐cage fluid (exudate), and noninflamed tissue‐cage fluid (transudate) were studied by using a tissue‐cage model. The in vitro and ex vivo activities of marbofloxacin in serum, exudate, and transudate against a pathogenic strain of Pasteurella multocida (P. multocida) were determined. Integration of in vivo pharmacokinetic data with the in vitro MIC provided mean values for the area under the curve (AUC)/MIC for serum, exudate, and transudate of 155.75, 153.00, and 138.88, respectively, after intravenous dosing and 160.50, 151.00, and 137.63, respectively, after intramuscular dosing. After intramuscular dosing, the maximum concentration/MIC ratios for serum, exudate, and transudate were 21.13, 9.13, and 8.38, respectively. The ex vivo growth inhibition data after intramuscular dosing were fitted to the inhibitory sigmoid E_max equation to provide the values of AUC/MIC required to produce bacteriostasis, bactericidal activity, and elimination of bacteria. The respective values for serum were 17.25, 31.29, and 109.62, and slightly lower values were obtained for transudate and exudate. It is proposed that these findings might be used with MIC₅₀ or MIC₉₀ data to provide a rational approach to the design of dosage schedules which optimize efficacy in respect of bacteriological as well as clinical cures.

Effects of High Pressure on Myofibrillar Protein and Moisture Distribution of Shrimp (Solenocera melantho) Muscle

ABSTRACT

The effects of high pressure (100–500 MPa) treatment on myofibrillar protein (MP) contents and distribution of water in Solenocera melantho muscle were investigated. The results showed that the shrimp treated with 200 MPa had the highest shelling score, and the solubility of MP in meat of shrimp treated with 300 MPa was significantly reduced. Moreover, the surface hydrophobicity of MP increased with increasing pressure. Treatment of shrimp with 200–300 MPa high pressure partially converted the structure of MP from an α-helix structure to a β-sheet structure, allowing for greater exposure of the tryptophan residues present. Treatment of shrimp with 100–200 MPa led to a significant loss in the amount of immobilized water in shrimp muscle. However, the treatment did not significantly change the moisture distribution. Overall, pressures of 100 to 200 MPa are considered the most suitable for the processing of S. melantho.
