皮脂腺

To explore the possibility that the androgen may facilitate differentiation of hair follicle stem cells into sebocytes, we carried out experiments to test this hypothesis. The concrete steps to carry out this research were as follow: Firstly, observed the expression of AR and examined the expression of AR mRNA of rat vibrissa follicle stem cells in vivo in three defined phases of a hair follicle cycle, including anagen, catagen and telogen. Secondly, cultured HFSC deprived from vibrissa follicle bulge region in culture flasks and observed the expression of AR, ketertin 15 (K15), cluster of differentiation 34 (CD34) andβ1-integrin of those cells.

为了探索雄激素对毛囊干细胞定向分化为皮脂腺细胞的过程是否具有促进功能，我们进行了如下的实验来进行研究：第一步，检测了在毛囊周期的三个不同时期(生长期、退化期和静止期)中大鼠触须毛囊干细胞中AR、ARmRNA的表达以及检测原代培养的毛囊干细胞中AR的表达并探讨意义，为进一步研究打下基础。

The plasmid of pEGFP-N1 was preserved in our laboratory.②The rat vibrissa follicles were dissected under a stereomicroscope. The dermal sheath was moved by incubated in dispase. The bulge regions of the hair follicles in anagen phase were carefully cut between the arrector pili muscle and the sebaceous gland, and then incubated with a mixture of trypsin and EDTA. The cell suspension was selected, and cultured in 10% fetal bovine serum DMEM/F12 FAD medium. After 7 days culture, HFSC was obtained by rapid adhering on collagen Ⅳ.

实验方法：大鼠在体视显微镜下分离出含真皮鞘的完整毛囊，dispase消化，将毛囊从真皮鞘中挤出，收集形态完好且处于生长期的毛囊，分别在毛球部上端、皮脂腺下端横切毛囊，取中间部分置于胰酶和EDTA中联合消化，向所得细胞悬液中添加含10%胎牛血清DMEM/F12完全FAD培养基，常规培养7 d后，采用IV型胶原快速贴壁法两次筛选以分离纯化大鼠毛囊干细胞。

Methods: The clinical data about 3 female cases of tuberous sclerosis accompanying bilateral and multiple renal angiomyolipomas were reported. Their age ranged 16-26 years. All the cases had typical facial angiofibroma and mental retardation. Of them, 2 were admitted to hospital for severe abdominal distending pain and shock, 1 was admitted to hospital for abdominal distention and epilepsy. Cranticocerebral CT revealed typical calcified cortical tuber and /or subependymal nodules, but no etrarenal organ angioleiomyoma in the 3 cases.

报告3例结节性硬化症伴多发性双肾AML的临床诊治资料。3例均为女性，年龄16~26岁，均有典型的智力低下、面部皮脂腺瘤体症，2例因腰部剧烈胀痛伴休克入院，1例因腹胀并癫痫发作入院。3例均经CT检查证实大脑钙化结节灶。

The portion of the follicle between the sebaceous duct and the insertion of the arrector pili muscle is the isthmus.

毛囊皮脂腺导管开口至立毛肌附着处为峡部。

Along one side of the follicle, two buds are formed: an upper, which develops into the sebaceous gland, and a lower, which becomes the attachment for the arrector pili muscle.

毛囊的一侧形成两个胚芽：上部胚芽生长进入皮脂腺，下部胚芽形成立毛肌的附着处。

It was found thatcomparing to controls the expression of AR in eccrine gland of male patients and in the basal layer, outer root sheath and arrector pili muscle of the female patients is significantly lower.

雌激素受体在基底层（＜0.05）、毛囊外根鞘（叩。05X皮脂腺o功。05X汗腺分泌部（功。01）及立毛肌瞩功刀1）女性患者阳性表达均明显高于正常对照；男性患者与对照组相比无显著差异；余部位比较在统计学上无显著差异。

On the other hand, several papers reported that COX-2 expressed constitutively in normal brain and kidney.

那么在正常的毛囊皮脂腺单位中COX-2是否存在表达，从而行使功能？

Mites such as demodex folliculorum and demodex brevis are natural hosts of the human pilo-sebaceous follicle.

螨类，如毛囊蠕形螨和蠕形螨的自然宿主是人类pilo -皮脂腺毛囊。

Results:Among the 123 cases of patients with nipple discarge, 63 cases were diagnosed as mammary duct inflammation, 30 cases were diagnosed as mammary duct ectasia, 26 cases were related single or multiple papilloma, early cancer were 3 case...

结果：123例有乳头溢液的患者中，乳腺导管炎63例，乳腺导管扩张症30例，乳腺导管内乳头状瘤或瘤病26例，导管内癌3例，乳头皮脂腺囊肿并感染1例。

The sebaceous gland is formed embryologically as an outgrowth from the upper portion of the hair follicle.

从胚胎学上来说，皮脂腺是从毛囊上部向外生长形成的。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
