Obtaining an Interspecific Hybrid of Cranes by Artificial Insemination with Frozen-thawed Semen
      
Studies of artificial insemination of cranes and cryoconservation of their semen have been carried out in the nursery of rare species at the Oka Biosphere Reserve for many years.
      
The criterion of successful cryoconservation of the semen is the obtaining of fertilized eggs after artificial insemination by the thawed semen.
      
An experiment is described on artificial insemination of females of the white-naped crane Grus vipio by the frozen-thawed semen of the Siberian white crane G.
      
Problems of artificial insemination and cryoconservation of semen of rare crane species are discussed.

1. The albino mice were used for this study. The Golgi apparatus in the cells of the epididymis and the vas deferens of normal, starved, and refed animals were studied.2. The amount of the Golgi elements can be maintained by feeding, not only by the sex hormone.3. The Golgi apparatus may be regarded as a product of food assimilation, not a definite cell organ.4. It is suggested that the Golgi apparatus has similar organ with that of mitochondria and secretion granules, but with different quantity of lipoids.

From February 1954 to February 1955, we have continuously studied the morphological changes of the reproductive glands of the Oncomelaniid snails once monthly by dissecting and serial sectioning. The snails used for this study, measuring within the range of 7.1 to 3.0mm., were collected from the banks of Ching-San River, Chungking, Kiangsu.The results of this study show that the reproductive glands of the Oncomelaniid snails, either male or female, exhibit periodic changes with hypertrophic and atro-phic phases...

From February 1954 to February 1955, we have continuously studied the morphological changes of the reproductive glands of the Oncomelaniid snails once monthly by dissecting and serial sectioning. The snails used for this study, measuring within the range of 7.1 to 3.0mm., were collected from the banks of Ching-San River, Chungking, Kiangsu.The results of this study show that the reproductive glands of the Oncomelaniid snails, either male or female, exhibit periodic changes with hypertrophic and atro-phic phases alternating with each other.From November to May of the following year, the ovary of the female snail is in the phase of hypertrophy. It is large, thick and prominent, containing a large number of eggs in the different stages of development. In June, some of the ovaries become smaller and thinner. From July to August, the ovary enters the atrophic phase, diminishing remarkably in size and containing only a small number of the primary oocytes. Beginning from September, the ovary shows signs of recovery and in October resumes its egg-producing capacity.From experimental and field observations, the female Oncomelaniid snails lay eggs from November to July of the following year, laying a large amount of eggs being laid from February to June, but no eggs at all from August to October. These findings are in agreement with the periodic changes of the ovary as shown above.The periodic changes of the testis, involving both hypertrophic or atrophic phases, appear about 4 months earliec than those of the ovary. From January to April, the testis appears atrophied, but in the vas deferens a large amount of spermatozoa is stored up. From May to August, the testis recovers gradually, being capable of producing spermatozoa, and from September to November it enlarges greatly, producing a large amount of spermatozoa. In December the testis again inclines to atrophy.From the field study, we know that the copulation of the Oncomelaniid snails takes place throughout the year, but more often during spring and autumn. Microscopic sections show that spermatozoa are found present in vasa deferentia every month, and in a greater amount in winter, spring and autumn. This would assure the fertilization of the eggs during the main copulation season.

从1954年2月到1955年2月,我们每月应用外形解剖结合组织切片的方法,观察了日本血吸虫中间宿主——钉螺生殖腺的周期变化。 雌螺卵巢在一年内有一度的周期变化。从11月到第二年5月,卵巢呈丰满而多卵的状态;6月卵巢趋向萎缩;7、8月卵巢萎缩,内仅含有少量的幼稚卵细胞;9月卵巢开始趋向丰满;10月卵巢逐渐恢复丰满的状态。卵巢全年周期变化的过程与镇江地区钉螺的产卵情况基本上相符合。 雄螺精巢在一年内也有一度的周期变化,但较卵巢要提早4个月左右。1—4月精巢呈萎缩状态,但输精管中尚储存有大量精子。5—8月精巢逐渐恢复原状,能产生少量精子,此时输精管中的精子还少。9—11月精巢特别丰满,含有大量精子。12月精巢开始萎缩。在9月以后,输精管中即逐渐储满了精子。输精管内精子储存的情况与南京及杭州地区钉螺的交配情况基本上相符合。

This paper deals with the anatomy of the reproductive system of the armyworm,Pseudaletia separata (Walker). The internal and external organs of both sexes aredescribed. On the part of the male internal organs, there are a pair of testes; the two testesof opposite sides are closely united as a single round organ enclosed in a common crim-son scrotum. The vasa deferentia are paired narrow tubes about 11 mm in length andthe basal section of each vas deferens is twice enlarged to form the seminal vesicles. Itwas found that the ductus ejaculatorius includes the paired anterior part, the ductusejaculatorius duplex, and the posterior single tube, the ductus ejaculatorius simple. Atthe apex of the ductus ejaculatorius duplex is situated a pair of accessory glands each ofwhich is measures 92--113 mm in length and 0.2--0.3 mm in diameter. The external genitalia of the male is extremely complex. Both the tegumen and thevinculum are articulated mid-laterally and therefore form a transverse narrow ring. At-tached to the mid-dorsal part of the tegumen is the uncus, the central hook of which issimple in form, and the socius situated on each side of the base of the uncus is found tobe soft and lobiform in structure. The gnathos lying beneath the tuba analis includesa sclerotized main plate, the cochlear and two lateral arms, the brachia. The largestportion of the male genitalia is formed by the paired clasping organs--the valvae; theymay be divided into four regions: upper, lower, central and distal. Detailed descriptionsare given to various parts of these regions. There is a long distal spine attached to theapex of the cucullus; it is a striking feature of P. separata and therefore may be usedfor distinguishing other species of the same genus. The phallus, or penis, consists of a bulbus, basal portion, the aedeagal coecum and aslender, terminal portion, the aedeagus. The structure of the spermatophore was examin-ed and described. The muscles of related organs in the male genitalia are mentionedalso. In the female, the internal reproductive organs are composed of a pair of ovaries,each of which consists of four polytrophic ovarioles. A pair of lateral oviducts, eachmeasuring 1 mm in length, unite posteriorly to form the oviductus communis of 3 mmlong. The latter connects with the vestibule opening to the exterior by the oviporus.Spermatheca, or the receptaculum seminis, is an organ consisting of a small lobe, the utriculus, and a large lobe, the lagena. The spermathecal gland opens at apex of theutriculus. Both the utriculus and the lagena unite at bottom, from which arises theductus receptaculi attached to the vestibula dorsally. A pair of accessory glands, eachranging from 30 to 55 mm in length, join the apex of two accessory gland reservoirsrespectively, which are attached to the accessory gland main reservoir at its middle. Theaccessory gland main reservoir enters the vestibula at its middle part. The essential parts of the reproductive system in the female are the bursa copulatrixand the ovipositor. The bursa copulatrix includes the ductus bursae, the corpus bursaeand the cervix bursae. The ovipositor is not a specialized structure. Its sterigma arealso briefly discussed.
