Abstract
  1. Chemical sympathectomy with 6-hydroxydopamine (6-OHDA) prevented the development of renal hypertension in 80% of weanling male rats of the C.F. strain.2. Adult male rats treated with 6-OHDA developed hypertension on bilateral clamping of the renal arteries.3. Demedullation of the adrenal glands followed by 6-OHDA treatment in adult rats prevented the development of hypertension in 75% of them.4. Weanling rats treated with 6-OHDA did not have any measurable catecholamines in their hearts up to 72-78 days after treatment.5. Unlike the weanling rats, the hearts of adult rats (demedullated or with intact medulla) showed significant refilling (40-50%) of catecholamine stores 60 days after 6-OHDA treatment.6. It is concluded that the functional sympathetic nervous system is important in the development of renal hypertension in the rat.
摘要
  1. 用6-羟基多巴胺(6-OHDA)进行化学性交感神经切除术可防止80%的C.F.品系断奶雄性大鼠发生肾性高血压。

  2. 用6-OHDA处理的成年雄性大鼠在双侧肾动脉夹闭后出现高血压。

  3. 成年大鼠肾上腺去髓质后再用6-OHDA处理,75%的大鼠可防止高血压的发生。

  4. 用6-OHDA处理的断奶大鼠在处理后72至78天内心脏中未检测到任何可测量的儿茶酚胺。

  5. 与断奶大鼠不同,成年大鼠(去髓质或髓质完整)的心脏在6-OHDA处理60天后儿茶酚胺储存有显著的再填充(40-50%)。

  6. 得出的结论是,功能性交感神经系统在大鼠肾性高血压的发生中很重要。
