采用紫外分光光度法测定氟苯尼考原料药及其注射液的含量。实验结果表明,在0.05~0.5 mg/mL浓度范围内,氟苯尼考的吸光度与浓度呈现良好的线性关系(r=0.9997,n=6);与法定的高效液相色谱法检测结果无差异。  相似文献   

Combined use of platelet rich plasma and vitamin C positively affects differentiation in vitro to mesodermal lineage of adult adipose equine mesenchymal stem cells

Repair of injured soft and hard tissues in horses can benefit greatly from the use of regenerative therapies with mesenchymal stem cells (MSC). Vitamin-C and platelet-rich-plasma had been used for in vitro differentiation of MSC. This study was aimed to evaluate the effect of vitamin-C, platelet-rich-plasma and their combination on the in vitro differentiation of adipose horse MSC. We isolated MSC from horse fat and differentiated them in vitro into osteogenic and chondrogenic lineages, as demonstrated by specific staining and RT-qPCR of selected genes. Combining vitamin-C and plasma-rich-platelet positively affected the ability of MSC to differentiate in vitro into mesodermal lineages during 14 days of culture; this effect was not as marked when differentiation was attempted for 21 days. This provides valuable information on the effect of combined use of these molecules in regenerative therapies and their potential application along stem cells for lesions of musculoskeletal tissue in sport horses.  相似文献

Rice-milk and rice-toasted mung bean diets, and a high-protein rice (IR58 milled rice) were evaluated as part of a study on the protein requirements of toddlers consuming rice-based diets following the multilevel N balance method. Milk or mung bean contributed 1/3 of dietary N. At a daily energy intake of 418 kJ/kg body weight, weight losses were observed for all diets. The safe level of protein intakes obtained allowing 10 mg N/kg body weight/day for miscellaneous integumental losses and 15 mg N/kg body weight/day for growth was 1.11 g/kg body weight/day for the rice-milk diet and 1.34 g for the rice-mung bean diet. Preliminary data on four children indicate a safe level of protein intake of 1.44 g/kg/day for the IR58 milled rice. The protein quality of the high-protein rice as determined by the very short term N balance index on three children was 79–80% relative to milk.  相似文献
