Therefore, in the present study, a retrograde and anterograde experiments were made in the rat to address this issue. After injection of cholera toxin B subunit, a retrograde tracer, into Barrington's nucleus or D-region, some retrogradely labeled neurons were found in lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus of the lumbosacral spinal cord segments. Injection of biotinylated dextran amine into lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus, respectively, a large number of BDA-labeled axon terminals were seen in Barrington's nucleus and D-region.

The barley chromosome in wheat was identified by genomic in situ hybridization in which biotin labelled total genomic DNA of barley betzes was used as probe and the unlabelled total DNA of common wheat Chinese Spring as blocking DNA. A series of wheat materials were tested as follows; two disomic alien substitution and monosomic alien addition lines, 2n=43; two monosomic alien substitution lines.

The distribution of γ-aminobutyric acid and serotonin (5-HT) immunoreactive neurons in the protocerebrum and deutocerebrum of the butterfly Minathyma schrenckii were studied with the Colophony-paraffin embedding serial section technique and the Streptavidin-peroxidase immunohistochemical method.

采用树脂石蜡(Colophony-Paraffin，CP)组织包埋切片技术和链霉菌抗生物素蛋白-过氧化物酶(Streptavidin-Peroxidase，SP)免疫组织化学方法，首次研究了 GABA 和5-HT 免疫阳性神经元在白斑迷蛱蝶前脑和中脑中的分布。

In situ hybridization using biotinylated POMC cRNA probe made it possible to localize POMC mRNA in the rat ovary. POMC mRNA predominantly existed in corpora lutea of diesturs, pregnant and pseudopregnant rat ovaries. POMC containing cells scattered in the ovarian intertitium were seen. The amount of POMC mRNA in granulosa cells was negligible.

采用生物素标记的POMCcRNA作为探针，进行原位杂文，研究POMCmRNA在大鼠卵巢中的分布，实验表明，POMCmRNA主要分布于间期，妊娠和假孕大鼠卵巢黄体中，间质细胞也可见少量POMCmRNA，而卵泡颗粒细胞中POMCmRNA极少。
