Neuroendocrine Study of the Korean Native Cattle: Pulsatile LHRH Release from Hypothalamic Tissues Superfused in vitor
한우의 신경내분비학적 연구 : 시상하부의 체외배양 조직에서 맥동적 LHRH분비 양상에 관하여
Abstract
Present study examined the endogenous release of luteinizing hormone releasing hormone (LHRH) from superiused hypothalamic sBces derived from Korean native cattie (KNC). In addition, the in vitro secretory pattern of LHRH release in '(NC was compared with that in imported cattle such as Holstein cow. The median eminences (ME) of hypothalamic tissues were disseded out, sliced and quici'ly placed in ice-cold superfilsion chamber. Superhision chambers containing ME slices were maintained in a constant temperature water-bath at 37
본 연구는 한우에서 적출한 시상하부조직을 superfusion 하여 체외배양 하면서 in vitro LHRH의 내인성 분비양상을 조사하였으며, 한우의 in vitro LHRH 분비양상과 수입소인 홀스타인 젖소의 LHRH 분비양상을 비교하였다. 시상하부의 median eminence조직을 적출하여 조각을 내어서 superfusion chamber에 넣은 후 37
