Abstract
- The lipids and fatty acids of the lipids of testes of rats aged 4 weeks to 6 months were separated and analysed. 2. A decrease in concentration of triglyceride was noted, but there was no significant change in the concentration of phospholipids, plasmalogen or cholesterol during this time. 3. There were no significant differences in the total lipid concentration of palmitic acid, stearic acid, linoleic acid, arachidonic acid and docosatetraenoic acid between the various age groups. 4. A decrease in the concentration of oleic acid in the phosphatide and triglyceride fractions and an increase in the concentration of docosapentaenoic acid (characterized as the Delta4,7,10,13,16-isomer) in phosphatides but not in triglyceride were observed during the maturation period. 5. Histological studies indicated that the lipid changes occurred at the same time as the appearance and maturation of the spermatids.
摘要
- 对4周龄至6个月龄大鼠睾丸脂质中的脂质和脂肪酸进行了分离和分析。2. 观察到甘油三酯浓度降低，但在此期间磷脂、缩醛磷脂或胆固醇浓度无显著变化。3. 各年龄组之间棕榈酸、硬脂酸、亚油酸、花生四烯酸和二十二碳四烯酸的总脂质浓度无显著差异。4. 在成熟期，观察到磷脂和甘油三酯组分中油酸浓度降低，而磷脂中二十二碳五烯酸（特征为Delta4,7,10,13,16-异构体）浓度升高，但甘油三酯中未升高。5. 组织学研究表明，脂质变化与精子细胞的出现和成熟同时发生。
