黑线仓鼠（Cricetulus　barabensis　Pallas）主动脉弓分支类型的初步观察

THE INITIAL OBSERVETION OF CRICETUTUS BARABENSIS PALLAS BRANCH TYPE OF ARCUS AORTAE

我们将我院黑线仓鼠（也叫中国地鼠）Ａ３０家系１只雌鼠（第２８代）和Ｂ５０２家系１５４只（从第１０—１５代）地鼠（其中雌性１３８只；雄性１５只），解剖观察了其主动脉弓分支的类型，共见到３个类型，Ａ型９７．４２％，Ｃ型１．２９％，Ｆ型０．６４％，并发现一例罕见畸型。而Ａ型为中国地鼠主动脉弓分支的基本类型，但基本型中又有各个亚型。

After having dissected one female-A30 family(the 28th generation),154 Chinese hamster-B502 family (the 10th～15th generation,138 females,25 males),we observed their branch type of arcus aortae and found 3 types,in which,97.42% of type A,1.29%of type C, 0.64% of type F and one rare deformity.Type A is the basic type of arcus aortae of Chinese hamster,which was also divided into several subsets.
