Immunocytochemical localization of GnRH (gonadotropin releasing hormone) systems in the brain of a marine teleost fish,the sole

Summary The GnRH system was studied in the brain of the sole by immunocytochemistry (peroxidase-antiperoxidase method) (PAP) using antibodies to synthetic salmon GnRH (s-GnRH). Two centers containing immunoreactive cell bodies were observed in the forebrain, one located at the junction between the olfactory bulbs and the telencephalon and the other in the preoptic area. Numerous immunoreactive fibers were found, especially in the telencephalon, hypothalamus, pituitary, optic tectum and retina.

天冬氨酸对家鸽顶盖脑片Ⅱa—f层神经元电活动的影响

利用离体脑片技术，在５１例家鸽顶盖脑片上用玻璃微电极胞外记录了家鸽顶盖Ⅱａ－ｆ亚层神经元的自发放电活动。根据家鸽顶盖Ⅱａ－ｆ 层神经元自发放电活动的特征，将Ⅱａ－ｆ亚层神经元自发放电分为３种类型：慢而不规则型、快连续型和周期性簇状放电型。天冬氨酸（Ａｓｐ）对不同形式放电单位的作用均以兴奋为主，这种兴奋作用能被Ｎ－甲基－Ｄ－天冬氨酸（ＮＭＯＡ）增强，Ｄ－α－氨基－己二酸（Ｄ－α－ＡＡ）能阻断ＡＳＰ的     

一氧化氮与心肌再灌注损伤

一氧化氮（NO）是一种生物信息递质，广泛存在于各种细胞和组织中，具有减少血小板聚集、抑制、嗜中性粒细胞聚集等功能。NF－KB被认为是近十年最有研究潜力的调节免疫反应、应激反应、凋亡和炎症的核转录因子。充分认识一氧化氮、NF－KB与心肌再灌注损伤的机制。为对其进一步研究提供理论依据。

Extracellular matrix and neuronal movement

Summary During brain development, both neuronal migration and axon guidance are influenced by extracellular matrix molecules present in the environment of the migrating neuronal cell bodies and nerve fibers. Glial laminin is an extracellular matrix protein which these early brain cells preferentially attach to. Extracellular glycosaminoglycans are suggested to function in restricting neuronal cell bodies and axons from certain brain areas. Since laminin is deposited along the radial glial fibers and along the developing nerve pathways in punctate form, the punctate assemblies may be one of the key factors in routing the developing neurons in vivo. This review discusses the role of laminin in neuronal movement given the present concept of the extracellular matrix molecules and their proposed interactions.     

Effect of phospholipids on purified lipoamidase

Summary Phospholipids were added to purified lipoamidase from porcine brain microsomal membranes, and changes in lipoamidase activity were examined. Approximately twofold activation of lipoamidase activity occurred upon the addition of phosphatidylethanolamine. On the other hand, phosphosphatidylserine, cardiolipin, and phosphatidic acid reduced the enzyme activity by approximately 80%. This pattern of the activation of lipoamidase by phosphatidylethanolamine and its inhibition by phosphatidylserine is similar to the pattern for adenylate cyclase, and contrasts with the pattern for ATPase.
