The study of Chinese Araliaccae(including those of Taiwan)reveals the occurrence of 19 genera, 162 species, 47 varieties and 11 forms, of which many are new to science. Owing to the similarity in its fruit and embryo to the Mastixia of Cornaceae, the genus Diplopanax is excluded herewith from the Araliaceae.New phylogenetic relationships of the Chinese genera of this family have been proposed by the author, who is of the opinion that in the study of phylogenetic relationships, emphasis should be laid not only...

The study of Chinese Araliaccae(including those of Taiwan)reveals the occurrence of 19 genera, 162 species, 47 varieties and 11 forms, of which many are new to science. Owing to the similarity in its fruit and embryo to the Mastixia of Cornaceae, the genus Diplopanax is excluded herewith from the Araliaceae.New phylogenetic relationships of the Chinese genera of this family have been proposed by the author, who is of the opinion that in the study of phylogenetic relationships, emphasis should be laid not only on the characters of the reproductive organs, but also on those of the vegetative distinctions of the examined genera as well. There are no direct phylogenetic relationships between the two genera except that all the distinctive characters of one genus are more advanced than, those of the other.The facts that the Chinese genera and species are mainly distributed in the south-western China, especially in the province of Yunnan, where the primitive forms, such as Tupidanthus, Trevesia, etc. occur in luxuriance, leads the author to believe that Yunnan and its neighborhood is possibly the motherland of the Indo-Malay distribution area of the Araliaceae.

本文分为三个部分:第一部分简略的报导我国五加科植物研究的历史和屬、种数目,目前我国五加科植物共有19(?)、162种、47变种和11变型,这一数目不包括应屬山茱萸科的马蹄参屬(Diplopanax)在内。 第二部分讨论五加科屬间的亲缘关系,提出了我国五加科一个新的屬间亲缘关系的意见,并给出了示意图,作者认为研究植物屬间的亲缘关系,必须根据科学的进化倾向,探讨各方面的性质,包括植物体的性状在内,凡是两个亲缘关系密切的屬,如其一个屬虽具有较另一个屬许多较进化的性状,但只要这—个屬具有一个较另一屬稳定的原始性状,即不能认为这一个屬直接起源于另一个屬,在研究屬间亲缘关系时,如果只注意于自已论点有利的性质,忽视对自已论点不利的性状,就不可能找出正确的系统关系。 第三部分讨论我国五加科植物的水平分布和垂直分布,我国西南、尤其是云南,不但具有本科现存最原始的屬和种,种类也远较其他各地为多,又富有不少特产种,而且从地形和环境条件来说也有其特点,所以著者认为这一地区有可能是本科植物在印度——马来分布区的起源地。

Adult Scfiistosoma japonicum worms obtained from the mesenteric veins of artificially infected mice were studied histochemically for the distribution of nucleic acids, amino acids, glycogen and phosphatases. The results obtained may be summarized below.1. Nucleic acids were seen mostly in the parenchyma cells and reproductive organs. In the testes, DNA was very rich, while RNA was found abundantly in the vitcllaria and ovary.2. The positive reaction for tyrosine, tryptophan and histidine was found in the...

Adult Scfiistosoma japonicum worms obtained from the mesenteric veins of artificially infected mice were studied histochemically for the distribution of nucleic acids, amino acids, glycogen and phosphatases. The results obtained may be summarized below.1. Nucleic acids were seen mostly in the parenchyma cells and reproductive organs. In the testes, DNA was very rich, while RNA was found abundantly in the vitcllaria and ovary.2. The positive reaction for tyrosine, tryptophan and histidine was found in the subcuticular muscles, ovary, testes, vitelline cells and the intestinal epithelium. The bromo-pheriol-blue test for basic proteins was strongly positive in the subcuticular muscles, parenchyma cells and vitellaria, while the positive reaction for ferricyanide method was found only in the cytoplasm of the vitelline cells. 3. Glycogen was richly distributed in. the parenchyma, especially in the region adjacent to the gynaccophoric canal of male worms. It was also present, though in small quantity, in the mature ovum.4. Alkaline phosphatase activity was most pronounced in the Cuticular layer and the epithelial cells of ootypc, while moderately positive reaction was observed in the excretory canal and vitelline cells. Acid phosphatase activity was shown most strongly in the subcuticular muscle layer and the parenchyma cells; the epithelia of the intestinal canal and the sexual glands showed also positive reaction.5. The role played by the substances demonstrated histochcmically in various organs of this fluke was discussed. It is suggested that the phosphatase activity in the cuticular layer might be associated with the active absorption of carbohydrates.

1.应用组织化学的方法研究了从小白鼠肠系膜静脉内取出的日本血吸虫成虫体内核酸、氨基酸、糖元和磷酸酶的分布情况。 2.成虫体内核酸的分布虽较广泛,但以雄虫的睾丸、雌虫的卵巢和卵黄腺中的含量为最高。在睾丸中主要为DNA,而卵巢和卵黄腺中则为RNA。 3.虫体的肌纤维、卵巢和睾丸中的生殖细胞核、卵黄细胞和肠管上皮细胞对显示酪氨酸、色氨酸和组氨酸的偶联重氮反应呈现阳性。角皮下肌层、实质组织细胞和卵黄细胞的颗粒滴呈强的溴酚蓝阳性反应。而对铁氰化物的反应仅卵黄细胞的颗粒滴呈现阳性。 4.糖元主要分布于虫体的实质组织和各种肌纤维内,尤以雄虫抱雌沟附近的实质组织内含量最多。在生殖器官中,仅成熟的卵细胞胞浆含有少许。 5.成虫体表角皮含有大量的碱性磷酸酶,而卵模上皮细胞、卵黄细胞和排泄管壁亦呈阳性反应。酸性磷酸酶主要分布于虫体的角皮下肌层、实质组织细胞核、肠管上皮细胞、雌雄生殖细胞和卵黄细胞内。 6.对于日本血吸虫体内各器官组织中所含的上述各种化学物质的生理意义进行了讨论,并认为血吸虫除肠道摄食外,尚可通过体表角皮吸收碳水化合物等营养物质。

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.
