By histological comparison, the structure of the autotomized tissue was different from other mantle tissue. Sinus and blood spaces were found in the autotomized tissue. Structural changes before and after autotomy in the autotomized tissue were from dense to sparse creases in the epidermis and dense to loose in the connective tissue.

组织学观察发现：自割组织结构与一般外套膜不同，具有血窦和较多的血腔；自割前之自割组织腹面表皮有很多褶皱，背面表皮则较平坦，内部组织紧密；自割后之自割组织膨大，背、腹面表皮形态改变，腹面表皮褶皱减少，内部组织蓬松。

By the same method, delta receptor was detected on the cerebral ganglia, pedal ganglia, visceral ganglia, coat ganglia and in the mouth, esophagus, craw, stomach, stomachic caecus, the epithelium of the intestines, sialoid gland, branchia, branchia gland, ventricle, branchial heart, kidneys, ovary, fallopian tube, back of mantle, abdomen of mantle, wrist, membrane of wrist, funnel and immunocytes of Octopus ocellatus.

Using the immunohistochemical technique, nerve cell bodies and fibres immunoreactive to the anti-Met-enkephalin sera were observed in the cerebral ganglia, pedal ganglia, visceral ganglia, inspect ganglia and coat ganglia of Octopus ocellatus. Met-ENK immunoreactivity was also localized in the mouth, esophagus, craw, stomach, stomachic caecus, the epithelium of the intestines, rectum, sialoid gland, liver, branchia, branchia gland, ventricle, branchial heart, kidneys, ovary, fallopian tube, back of mantle, abdomen of mantle, wrist, membrane of wrist, funnel, and immunocytes of Octopus ocellatus.

免疫组织化学定位结果表明：(1)在短蛸的脑神经节、足神经节、脏神经节、视神经节、外套神经节、口球、食道、嗉囊、胃、胃盲囊、肠、直肠、前唾液腺、后唾液腺、肝胰脏、鳃、鳃腺、心室、鳃心、肾静脉腺质附属物、卵巢、输卵管腺、外套膜背面、外套膜腹面、腕、腕间膜、漏斗中检测到呈不同阳性反应的Met-ENK分子。

It also has a pair of chelicera in an aciform, and the pedipalp is divided into three parts.

躯体分足体和末体两部分，足体腹面有足4对，粗短呈芽突状。

Spikelike inflorescence linear to narrowly cylindric, long, thin, loose, and at maturity often interrupted.

在腹面的缝上有毛唯一，在别处无毛的心皮 19

Mu opioid receptor was not observed in the wrist, funnel, abdomen of mantle, mouth, craw, stomach theca, intestine, rectum, sialoid gland, liver. Weak positive mu opioid receptor immunoreaction was found in inner epidermis, ectoblast, connective tissue of the esophagus and the keratolytic of the stomach and positive immunoreaction in epidermis of back of mantle and membrane of wrist.

结果表明，短蛸腕、漏斗、外套膜腹面、口球、嗉囊、胃盲囊、肠、直肠、前唾液腺、后唾液腺、肝胰脏均呈μ受体阴性，但食道内上皮、外膜、结缔组织和胃角质层有μ受体分布，外套膜背面、腕间膜的上皮或近上皮部位呈μ受体阳性。

Thereafter, Foxa2 is expressed in the notochord, gut endoderm and ventral midline of the CNS.

此后， Foxa2体现在脊索，肠道内胚层和腹面中线的中枢神经系统。

Antheridia occurred in the cushion on the dorsal and ventral surfaces of gametophytes while archegonia were observed on the ventral surface only. On hermaphroditic gametophytes, antheridia and archegonia were usually intermingled. Both types of gametangia were eusporangiate.

藏精器与藏卵器分别在孢子洒播10及12月后发生；藏精器长在中肋的背面及腹面，藏卵器只在腹面发生；两性配子体的藏精器与藏卵器混生一起，两者均属厚囊蕨型。

Staff of the Nantou Forestry Management Office custom designed a nest box with a built-in camera to watch the reproduction and behavior of these birds.

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
