Abstract

INTRODUCTION . Neuropeptide Y (NPY), a 36 amino acid neurotransmitter/neuromodulator, is involved in food intake and parental cares in birds. NPY is associated with the regulation of the reproductive system in the female native Thai chickens. However, the role of NPY in the male native Thai chicken has not been studied. Therefore, the objective of this study was to investigate the distributions of NPY immunoreactive (-ir) neurons and fibers in the brain of the male native Thai chickens. MATERIAL AND METHODS . The distribution of NPY-ir neurons and fibers in the hen brain was elucidated utilizing immunohistochemical technique. RESULTS . The distributions of NPY-ir neurons and fibers were located throughout the brain, predominantly in the hypothalamus. The numbers of NPY-ir neurons within the nucleus paraventricularis magnocellularis (PVN) were significantly higher than those of the nucleus septalis lateralis (SL), nucleus supraopticus (SOv), and nucleus inferioris hypothalami and nucleus infundibuli hypothalami (IH-IN). In addition, the numbers of NPY-ir neurons within the SL, SOv, and IH-IN were significantly higher than those of the tractus septomesencephalicus and nucleus dorsolateralis anterior thalami. CONCLUSIONS . These results indicated, for the first time, that the distributions of NPY-ir neurons and fibers in the brain of the male native Thai chickens were markedly observed in the hypothalamus, especially within the PVN, implicating that the NPYergic system within the PVN might be related to the regulation of feeding behavior and parental cares in this equatorial species.

神经肽Y在雄性泰国土鸡脑中的分布。

引言。神经肽Y（NPY）是一种36个氨基酸的神经递质/神经调节剂，与鸟类的食物摄入和父母照顾有关。NPY与泰国雌性土鸡生殖系统的调节有关。然而，NPY在雄性泰国土鸡中的作用尚未得到研究。因此，本研究的目的是研究NPY免疫反应（-ir）神经元和纤维在泰国雄性土鸡脑中的分布。材料和方法。应用免疫组化技术阐明了NPY-ir神经元和纤维在母鸡脑中的分布。结果。NPY-ir神经元和纤维分布于整个大脑，主要分布在下丘脑。大细胞脑室旁核（PVN）内的NPY-ir神经元数量显著高于纵隔外侧核（SL）、视上核（SOv）、下丘脑下核和下丘脑漏斗核（IH-IN）。此外，SL、SOv和IH-In内的NPY-ir神经元数量显著高于中脑隔束和丘脑前背外侧核。结论。这些结果首次表明，在雄性泰国土鸡的下丘脑中，特别是在PVN内，显著观察到NPY-ir神经元和纤维在大脑中的分布，这表明PVN内的NPY能系统可能与该赤道物种的喂养行为和父母照顾的调节有关。

期刊介绍： "Folia Histochemica et Cytobiologica" is an international, English-language journal publishing articles in the areas of histochemistry, cytochemistry and cell & tissue biology. "Folia Histochemica et Cytobiologica" was established in 1963 under the title: ‘Folia Histochemica et Cytochemica’ by the Polish Histochemical and Cytochemical Society as a journal devoted to the rapidly developing fields of histochemistry and cytochemistry. In 1984, the profile of the journal was broadened to accommodate papers dealing with cell and tissue biology, and the title was accordingly changed to "Folia Histochemica et Cytobiologica". "Folia Histochemica et Cytobiologica" is published quarterly, one volume a year, by the Polish Histochemical and Cytochemical Society.
