雌性

According to the results, we can find that female reproductive systemis made up of ovary, lateral oviduct, common oviduct, spermatotheca, accessory glandand genital chamber, which is typical polytrophic type. Then the male reproductivesystem consists of testes, vas deferens, vas efferens, seminal vesicle, ejaculatory duct,male accessory gland and pygostyle. Moreover accessory gland is fully developed,seminal vesicle is unclear, males testes and testicular follicle has degenerated before itflying, and the quantity of testicular follicle is different from the other kind of ants.

结果发现，拟黑多刺蚁的雌性生殖系统由卵巢、输卵管、中输卵管、受精囊、生殖腔和雌性附腺等结构组成，为典型的多滋式卵巢；雄性生殖系统由精巢、侧输精管、输精管、贮精囊、射精管、雄性附腺及阴茎等结构组成，雄性附腺发达，贮精囊不明显，婚飞前雄蚁的精巢及精巢小管已逐渐退化，精巢小管的数量与其它种类蚂蚁存在一定差别。

Affusing different-dosage female silkworm moth to female immature rat, the independent activity times, twisting times, surviving time, drop asleep delitescence and sleep times of rat were observed and rat's body, uterus and ovaries were weighted.

给雌性幼鼠灌胃不同剂量的家蚕雌蛾粉，通过对小鼠自主活动次数、扭体反应次数、入睡潜伏期、睡眠时间、游泳存活时间、体重、子宫卵巢系数等指标的考察，研究家蚕雌蛾粉对雌性幼鼠的药理作用。

American Cancer Institute toxicologist Xu said: Overall, the original skim milk in less estrogen, but other forms of estrogen are more.

The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

When the male is interested in breeding he will crawl on top of the female forming a zig zag pattern and begin courtship "squeezing her" in 5-60 second intervals.

如果雄性有兴趣进行交配，他将爬在雌性身上形成Z形形状，并在5-60秒内开始对雌性进行摩擦挤压。

Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones.

结果 妊娠20d时，孕鼠体重随DBTD剂量升高呈下降趋势，但与对照组比较，差异无统计学意义，30mg/kg组孕鼠子宫重量显著降低；所有DBTD染毒组雄性、雌性胎鼠体重均显著降低，20、30m/kg组胎鼠体长显著降低；所有DBTB染毒组雌性胎鼠肛门距生殖器的标化距离显著增长，而雄性胎鼠无显著变化。

Results After 4 weeks medication, the gain weight、LH in serum、growth of uterus and ovary be slower significantly. Kangzao-Ⅱ Decoction can reduce asteroidal colloid cell in hypothalamus and acidophil cell in pituitary which secrete FSH and LH.

结果 抗早2号方对青春期雌性SD大鼠的体重增长有抑制作用，能明显抑制血清LH水平，使大鼠的子宫腺体发育延迟，卵巢内卵泡发育滞后，能使青春期雌性SD大鼠的下丘脑星形胶质细胞数量减少，体积缩小，使脑垂体分泌促卵泡生成素和LH的嗜酸细胞减少。

Bonnethead shark Females of this small hammerhead shark species were thought to mate with several males and store their sperm for later use, so scientists assumed the resulting litter of baby sharks would have several different fathers.

窄头双髻鲨科学家曾认为，雌性窄头双髻鲨有不同的性伴侣并将不同的雄鲨*储存在体内供今后孕育幼鲨，于是雌性窄头双髻鲨产下的每胎小鲨鱼都可能有若干个父亲。

The male and female offspring were sacrificed at PND 56, 98, and 140 respectively. The prostate, levatro ani bulbocavernosus and bulbourethral glands relative weights at PND 56, and epididymis and LABC relative weights at PND 98 of ME group male offspring were increased significantly.

雄、雌性仔鼠分别於 PND 56、98 与 140 时牺牲，雄性仔鼠在 PND 56 的前列腺、提肛与球海绵体肌与尿道球腺，及 PND 98 时副睪与 LABC 相对重量明显上升；暴露组雌性仔鼠於 PND 56 时卵巢相对重量有明显上升，而在 PND 140 肝脏相对重量则显著下降。

Reduction of ovule number as a tendency of speciation in the genus is substantiated by the occurrence of tri_ovulate cones coupled with comprehensive characters of the genus. The metamorphic patterns as well as the leaf nature of the outer envelope indicate that female cones of Ephedra are compound while the female reproductive units of the ovulate cone have been reduced from secondary reproductive shoots similar to those of cordaites by phylogenetic transformation, fusion and reduction. Each fertile bract together with its axillary female reproductive unit composed the Bract Scale and Seed Scale Complex of Ephedra .

基于返祖性畸形三胚珠球花的出现及其他形态特征，认为麻黄属胚珠数目减少是该属内物种特化的一个趋势；利用雌球花发育的畸形现象及外珠被的形态学本质提出麻黄属的雌球果为复轴性构造，雌性生殖单位是由类似于科达类的次级生殖枝构造经系统发育变态、融合、简化成现存的生胚珠构造式样，每一可育苞片及其腋内雌性生殖单位共同组成了麻黄属的苞鳞_种鳞复合体。
