坚盘属(Pycnoporus)吸虫的分类及三新种的描述(吸虫纲:枝腺科)

关于我国枝腺科(Lecithodendriidae Odhner,1911)吸虫,福井玉夫与尾形藤治(1939)曾报告东北地区所采得的肠前腺属(Prosthodendrium)吸虫一种;陈心陶(1954)对肠前腺属吸虫的分类进行了研究,记载了华南地区采得的肠前腺属吸虫六种,并将肠前腺属中具有长形口吸盘与长形口的虫种分出,另建长吸盘属(Longitrema Chen,1954)。综上所述,我国已有记载的枝腺科吸虫仅肠前腺属六种,本科其他属虫种尚未见文献记载。作者

三种危害性纤毛虫的形态学研究

三种分离自海水养殖水体中的纤毛虫原生动物,含一新亚种及两种国内新记录：相似瓜形膜袋虫,有唇蓝口虫和贪食拟阿脑虫;本文对其纤毛图式及重要的形态学特征做了综合的描述。有唇蓝口虫为可导致水质恶化的赤潮生物,其余两种则有明显的嗜污习性,或附着养殖动物的浅表倍位从而有可能构成对宿主的危害。

Recent advances in the study of Kaposi's sarcoma-associated herpesvirus replication and pathogenesis

It has now been over twenty years since a novel herpesviral genome was identified in Kaposi's sarcoma biopsies. Since then, the cumulative research effort by molecular biologists, virologists, clinicians, and epidemiologists alike has led to the extensive characterization of this tumor virus, Kaposi's sarcoma-associated herpesvirus(KSHV; also known as human herpesvirus 8(HHV-8)), and its associated diseases. Here we review the current knowledge of KSHV biology and pathogenesis, with a particular emphasis on new and exciting advances in the field of epigenetics. We also discuss the development and practicality of various cell culture and animal model systems to study KSHV replication and pathogenesis.     

The structure, reproduction and taxonomy of Vidalia and Osmundaria (Rhodophyta, Rhodomelaceae)

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.     

New or rare chromosome counts in Artemisia L. (Asteraceae, Anthemideae) and related genera from Kazakhstan

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.
