Abstract
Proctolin at concentrations 10(-8)-10(-7) M elevated by 40% brain adenylate cyclase activity of adult Locusta migratoria migratoriodes R.F. In moulting individuals, proctolin caused a decrease in brain adenylate cyclase activity, and it proved to be ineffective in the larvae. Proctolin caused only a slight decrease on guanylate cyclase activity of the brain at every developmental stage.
摘要
浓度为10⁻⁸ - 10⁻⁷ M的促肠动素使成年飞蝗（Locusta migratoria migratoriodes R.F.）的脑腺苷酸环化酶活性提高了40%。在蜕皮个体中，促肠动素导致脑腺苷酸环化酶活性降低，并且在幼虫中证明其无效。在每个发育阶段，促肠动素仅使脑鸟苷酸环化酶活性略有降低。
