In the present study, a series of experiments was carried out to test the effects ofdifferent diets on the development of ovaries of the adult housefly. Three kinds of dietswere used in the experiments. They were: (1) 10% sucrose solution; (2) hen's eggsolution (one part of egg and three parts of water) plus 10% sucrose solution; (3) thesynthetic diet which was prepared according to the components of hen's egg, consistingof arachis oil, sucrose, vitamin B_1 and B_2, nicotinic acid, cholesterol, calcium phosphate,ferric phosphate and amino acid mixture (including arginine, histidine, lysine, isoleucine,leucine, phenylalanine, threonine, valine, tryptophane, methionine, glutamic acid, tyrosine,aspartic acid, cystine, alanine and glycine) plus 10% sucrose solution. In flies fed with hen's egg plus 10% sucrose solution, the ovaries developed nor-mally, the complete ovarian maturation occurred on the fifth and the eggs were laid onthe sixth day following emergence. The longevity of female flies was up to 55 days. The ovaries in the housefly are of the polytrophic type containing numerous ovarioles.Only one egg from each ovariole matures at one time and all the eggs in one fly areat the same stage of development. According to the size of the ovary and ovariole,amount of yolk deposited and the morphological alteration of the ovum and nurse cells,five more or less clear-cut stages of ovarian development have been established. In flies fed with sucrose solution, ovarian growth ceased at an early stage (stage Ⅱ). In flies fed with synthetic diets, the condition of the development of ovaries wasalmost the same as those flies fed with hen's egg solution, except the length of life wasslightly shorter (35 days in average). Therefore this defined diet is a nutritionally suf- ficient diet for maintaining the life of the adult housefly as well as for its ovariandevelopment. The main purpose of the present studies was to test the egg production of thehousefly on a synthetic diet in which the protein was replaced by amino acids and todetermine the so-called indispensable amino acid requirements for the development ofovaries of the adult housefly. It was found that arginine, lysine, tryptophane, phenyl-almine, threonine, leucine, isoleucine and valine are needed for ovarian development.The absence of any one of these eight amino acids apparently prevented the formationof eggs. As the ovaries could develop normally on histine- or methionine-free diets, itis assumed that the development of ovaries is not prevented by the omission of any ofthese amino acids from diet.

本研究以10%蔗糖水,鸡蛋液加10%蔗糖水,及以16种氨基酸代替鸡蛋液中的蛋白质所配合成的试验饲料加蔗糖水,分别饲养家蝇,作为营养物质与卵巢发育关系的试验。试验结果证明:家蝇单取食蔗糖水,卵巢不发育;取食鸡蛋液加蔗糖水,卵巢正常发育;取食配合的试验饲料加蔗糖水,卵巢亦能正常发育。 取食鸡蛋液加蔗糖水的雌蝇,羽化后5天,卵巢发育完成,第6天产卵。其寿命可达55天。这种食物满足了家蝇成虫正常生活及繁殖的需要。根据卵巢发育过程中卵巢管的变化,卵母细胞和滋养细胞的发育变化情况,卵巢的发育可明显地区分为五个阶段。本试验以这样的五个发育阶段作为营养物质与卵巢发育关系的根据。 单取食10%蔗糖水的雌蝇,卵巢仅发育到第Ⅱ阶段,即停留在卵母细胞分化初期,卵黄未开始形成的阶段。 取食试验饲料的家蝇,其寿命平均35天;在卵巢发育过程中,其增长程度与取食鸡蛋液者相似,最终卵巢直径较取食鸡蛋液者略小,但差异不显著,能正常产卵,并能正常孵化,其后代均能正常生长发育及繁殖。这个试验结果证明:配合的试验饲料完全可以代替作为家蝇食物的鸡蛋液,并可作为家蝇食物中某种氨基酸的存缺与卵巢发育关系的试验饲料。 在这种配合饲料的基础上,分别除去其中十种...

The influence of sex hormones on the differentiation of gonads and gonaducts in the fowl has been the concern of a large number of investigators. They studied the effects of various kinds of sex hormones on the sexual differentiation of chick embryos and young birds and discussed the mechanism of development of reproductive organs in relation to the action of sexual hormones. But most of the authors either did not use the embryos and the chicks of genotypically known sex as experimental materials or only investigated the action of sex hormones on the development of the reproductive systems anatomically. The present authors made use of the autosexing embryos and chicks as experimental materials, and investigated the action of sex hormones on the differentiation of gonads and gonaducts anatomically as well as histologically in order to elucidate the mechanism of sexual differentiation on a more sound basis.All the eggs used in this study were obtained from the crosses between barred hens and non-barred cocks, giving only barred males and non-barred females. The hormonal treatments were given by two different methods, one was injection of hormones into the un-incubated or incubating eggs, and the other was immersion of un-incubated eggs in hormone solutions. In the former, the female sex hormones diethylstilbestrol, estradiol, hexesterol and ovarian tissue extract and the male sex hormone testosterone were employed, while in the latter, however, only the female sex hormone diethylstilbestrol was used. The main results of the hormone treatments thus obtained are presented schematically in the accompanying table.Since in the initial stage of sexual differentiation, the gonads are amphisexual, the left gonad of birds possesses two components, an outer ovarian cortex and an inner portion, the medulla; the right gonad primordium, on the other hand, consists of only the medullary portion, generally lacking the incipient ovarian epithelium. The female hormones tend to activate the female component in embryos of either sex and suppress the male components. The male hormone has just the opposite effect, it stimulates the male component and suppresses the female component. After the treatment of female sex hormone, the gonads of genetic male birds tend to be flattened, with cortex thickened to form a kind of ovatestes. After the treatment of male hormone, on the contrary, the left gonad of the genetic female tends to be elongated, and to form a structure similar ??to that of the male sex cords, but the right gonad is not affected to any visible degree. In most of the cases, the latter remains to be small or degenerated completely.The degree of sex reversal depends to a large extent on the quantity of hormones given, the heavier the dosage used, the more complete with the sex reversal. But in no case complete sex reversal has been observed even though the dosage employed was as high as 2 mg. This suggests that the direction of sex differentiation is primarily controlled by the quantitative balance between the opposing sets of male and female determining genes. The moditications in the course of sexual differentiation as affected by the treatment of sex hormones are probably secondary in nature.In the development of male birds, the Müllerian ducts disappear entirely and the Wolffian ducts persist as the vasa differentia. In the case of females, the left Müllerian duct persists as the functional oviduct, the right one degenerating and the Wolffian ducts only persist in a rudimentary state. After hormone treatment, the Müllerian ducts persist, though somewhat hypertrophied, regardless whether the treated animals are genotypic males or females. This may be explained as either due to that the administrated hormones disturb the normal differentiation courses of the Müllerian ducts directly or due to that administrated hormones interfere with the normal differentiation of the gonads, and then cause the abnormal retention of the Müllerian ducts.

Female pupae of Ostrinia nubilalis (Hubner) were irradiated with gamma-rays(Co~(60)) at different stages of their development, after which their ovaries were examinedfor histopathological changes in germaria and in growing egg follicles. The effects ofgamma-irradiation, inrespective of the dosages used (16000, 20000 and 30000 roentgens)and the pupal stages treated, were found to be the same. The nuclei of nurse cells werefound to become sensitive to gamma-irradiation at a certain stage during their endomi-totic cycle, their destruction induced the degeneration of the entire egg follicle. Thenuclei of oogonia were also destroyed when irradiated at their sensitive stage during themitotic cycle. When irradiated at the resistant stage they were found to be normal infurther development but produce dominant lethal eggs which failed to complete theirembryonic development. No ovarian tumour has been observed in our experiments. Thedegeneration and resorption of the ova in the egg follicles were not due to the directdestructive effect of the irradiation, but to the lecitholytic action of follicle cells in theegg follicles whose normal metabolism has been disturbed by irradiation. Tissues ofmesodermal origin, such as the prefollicular epithelium, the follicle cells, the ovarian sheathand the oviductus lateralis, were not effected by gamma-irradiation.

以钴~(60)的丙种射线处理不同发育期的玉米螟雌蛹,观察其卵巢内原卵区与发育中印包囊的组织病变,发现在不同剂量(16000、20000及30000伦)及不同处理时期下射线的作用均相同。滋养细胞核在其内分裂周期的一定阶段对射线甚为敏感,其破坏造成整个卵包囊的退化。卵原细胞在其有丝分裂周期的敏感阶段处理时亦被破坏,而在其抗性阶段处理时则可正常发育,但形成显性致死卵。试验中未曾发现卵巢肿瘤。如包囊内卵的退化与吸收并不是射线的直接破坏作用,而是卵包囊正常代谢被破坏后卵包细胞的消黄作用。前卵包上皮、卵包细胞、卵巢管鞘及侧输卵管等来自中胚层的组织不受射线的影响。
