Abstract
- A study of the activity of cysteamine in relation to juvenile hormone (JH) production in adult females of Blattella germanica was carried out. 2. In vivo assays showed that cysteamine stimulates protein synthesis in the left colleterial gland and, in some instances, enhances oocyte growth. 3. In vitro assays demonstrated that cysteamine enhances JH release by incubated corpora allata (CA), and that this effect is more pronounced when using CA from 10-day-old females (period of ootheca transport), either connected to the corpora cardiaca (CC) or to the CC and to the brain. 4. Possible antiallatostatic effects of cysteamine are discussed.
摘要
- 开展了一项关于半胱胺活性与德国小蠊成年雌性体内保幼激素（JH）产生关系的研究。2. 体内试验表明，半胱胺刺激左输卵管腺中的蛋白质合成，在某些情况下还能促进卵母细胞生长。3. 体外试验证明，半胱胺可增强离体咽侧体（CA）释放JH，当使用来自10日龄雌性（卵鞘运输期）的CA时，这种效应更为明显，无论该CA是与心侧体（CC）相连，还是与CC和脑相连。4. 讨论了半胱胺可能的抗咽侧体抑制作用。
