本文采用ATP酶染色法和单克隆抗体OKT6免疫金银染色法,对人的皮肤、扁桃体、子宫颈阴道部和食道上皮中的郎格罕细胞(LC)进行观察。结果证明,这些器官的复层扁平上皮中均有郎格罕细胞分布。LC主要位于表皮棘细胞层和毛囊根鞘;皮脂腺腺泡周围亦有少量LC分布。扁桃体、子宫颈和食道复层上皮中,LC主要分布于上皮基底层上方和中间层。扁桃体的淋巴组织内、子宫颈阴道部和食道固有膜内,均未见LC分布。本文还用ATP酶染色法,观察了不同年龄组和不同部位表皮中LC的分布。结果表明,表皮内LC的密度和形态与年龄和不同的体表解剖部位有关。各年龄组表皮内LC密度从低到高的顺序为:胎儿组<1～9岁组和50～90岁组<10～19、20～29和30～49岁组(P<0.01);不同部位表皮内LC密度从低到高的顺序为:手掌、足跖部<手、足背<躯干和四肢其它部位<额部(P<0.01)。
In this study, human gastric epithelium, amygdala, cervicovaginal and Langerhans cells (LC) in esophageal epithelium were observed by ATPase staining and OKT6 immunogold-silver staining. The results show that these organs have stratified squamous epithelium Langerhans cell distribution. LC mainly located in the epidermal spinous layer and the root sheath of hair follicles; sebaceous acinar also has a small amount of LC around the distribution. In the amygdala, cervix and esophageal mucosa epithelium, LC is mainly distributed above and in the middle of the basal layer of epithelium. Tonsils lymphoid tissue, cervix vagina and esophageal lamina propria, no LC distribution. In this paper, ATPase staining was also used to observe the distribution of LC in the epidermis of different age groups and different parts. The results showed that the density and morphology of LC in the epidermis were related to age and different anatomical parts of the body surface. The order of LC densities in the epidermis of all age groups from low to high was as follows: fetal group <1-9 years old and 50-90 years old <10-19, 20-29 and 30-49 years old (P <0.01); different The order of LC densities in the epidermis from low to high was: palms, plantar

一家大公司对外招寡人才，有三个人前来面试。负责招聘业务的主管拿出一根大约5斤多重的甘蔗问第一个面试者：“你覺得这根甘蔗值多少钱?” 第一个应聘者觉得招聘主管提出的问题可笑而且简单，于是便脱口而出：“市面上的甘蔗大约是1块钱1斤，所以这根甘蔗的价值应该是5块钱。”招聘主管站起身来，微笑着宣布他正式成为公司员工，理由是回答诚实本分。第二个应聘者则回答：“如果搞批发，一斤只要4毛钱，那这根甘蔗的价值就
近十多年来,世界天然铀生产方法发生了重要变化。1990年,世界铀矿山产量的55%来自于地下常规开采方法,但是,从1999年开始,地下常规开采方法生产的铀大幅萎缩(33%左右)。
