Abstract
- A cannulation technique is described for measuring arteriovenous differences across the lactating-rabbit mammary gland. 2. Analysis of milk obtained before and after surgery shows no effect of cannulation on milk constituents. 3. Results of blood analysis show significant net changes in the concentrations of glucose, acetate, 3-hydroxybutrate, triacylglycerols and non-esterified fatty acids across the mammary gland. 4. The molar proportions of individual fatty acids in both the triacylglycerol and non-esterified fatty acid fractions did not alter between the arterial and venous samples. 5. The extraction rates are compared with those obtained from other species.
摘要
- 描述了一种用于测量泌乳兔乳腺动静脉差异的插管技术。2. 对手术前后采集的乳汁进行分析表明，插管对乳汁成分没有影响。3. 血液分析结果显示，乳腺中葡萄糖、乙酸盐、3-羟基丁酸盐、三酰甘油和非酯化脂肪酸的浓度有显著的净变化。4. 动脉血和静脉血样本中，三酰甘油和非酯化脂肪酸组分中各脂肪酸的摩尔比例没有变化。5. 将提取率与从其他物种获得的提取率进行了比较。
