东北龙胆地上、地下器官成分积累规律研究

研究龙胆地上器官和地下器官成分积累相关规律 .采用高效液相法 .地下器官中 ,龙胆苦甙含量高于当药苦甙含量 ;而地上器官中当药苦甙含量高于龙胆苦甙含量 .茎中龙胆苦甙含量降低时 ,叶中含量升高 ;当茎中龙胆苦甙含量升高时 ,叶和花中龙胆苦甙含量降低 .同时 ,茎和根中龙胆苦甙和当药苦甙基本上同步上升 ,也同步下降 .可能存在着花期时有效成分向上输送 ,而花期后有效成分向下输送的趋势     

Molecular phylogenetic analysis of three groups of Asian epilachnine ladybird beetles recognized by the female internal reproductive organs and modes of sperm transfer

We determined partial sequences of the nuclear 28S ribosomal RNA gene (717 base pairs) and mitochondrial DNA NADH-dehydrogenase subunit 2 gene (535 base pairs) of 25 species of phytophagous ladybird beetles from Asia that comprise 16 species of the genus Henosepilachna and nine species of the genus Epilachna, and reconstructed the phylogenetic trees for each gene by the maximum parsimony and maximum likelihood methods. The estimated phylogenetic relationships were consistent with those obtained by the mode of sperm transfer and female internal reproductive system, and supported an earlier assumption that very similar elytral spot patterns of some sympatric members of epilachnine beetles evolved independently.     

论监察机关的法律定位——理论与实践的视角

监察机关是国家行政机关体系内的监督机构,独立行使监察权。监察机关是＂局外人＂,＂幕后人＂,就像是电脑的杀毒软件,只有在电脑工作程序可能或已受到病毒侵蚀时才发挥作用。实践中,监察机关应当科学把握自己的法律地位,不可越位、错位,也不应不到位。     

A new polychaete genus and species of the Kongsfjorden,Spitsbergen, Svalbard

Glyphochaeta laudieni, a new genus and species of the “Spionidae”, is described from the Arctic. The specimens were collected from the Kongsfjorden, Spitsbergen, Svalbard, in a marine grotto. Glyphochaeta laudieni was associated with colonies of unidentified Bryozoa. This new genus and species is characterized by a prostomium with frontal horns, the absence of branchiae and sabre chaetae, and the presence of grooved spines which replace hooded hooks in some chaetigers of the middle body region. These spines are associated with glandular organs situated in neuropodia. The significance of characters for determining the systematic position of Glyphochaeta within “Spionidae” is discussed. Glyphochaeta laudieni is probably related to Pygospio elegans.     

Five new Polycladida (Platyhelminthes: Acotylea) species from the Aegean Sea with remarks on the prostatic structures

Five species of polyclads, Imogine melihertani sp. nov., Pseudoplanocera izmirensis gen. et sp. nov., Izmira cinari gen. et sp. nov., Izmira turkeyi sp. nov. and Pseudodiscocelis aegeanensis gen. et. sp. nov., were collected in Izmir Bay, Turkey, Aegean Sea. I. melihertani is characterized by an anchor-shaped seminal vesicle, penis papilla, and ciliated male and female atria. P. izmirensis possesses spermiducal bulbs, a free prostatic vesicle, cirrus bulb, armed cirrus and Lang's vesicle. The genus Izmira is established based on the presence of a penis rod, true seminal vesicle, an interpolated prostatic vesicle of atomata-type and vagina bulbosa. Izmira cinari has an elongated body; a pointed penis and the oviducts enter the vagina bulbosa separately. Izmira turkeyi is characterized by an oval body, rod-shaped penis and the oviducts join before entering the vagina. Pseudodiscocelis is characterized by prostatoid organs, a lobed penis and ciliated and glandular cells in the male antrum.     

普通级长爪沙鼠内脏器官重量和含水量的测定

测定了长爪沙鼠内脏器官的绝对重量、相对重量(脏器指数)和含水量的年龄变化,并对其进行了统计学处理．结果表明：长爪沙鼠心、肺、肝、肾、肾上腺和子宫的绝对重量与年龄显著相关,脑、肾脏和子宫的相对重量与年龄显著相关,除睾丸外其他脏器的含水量无明显的年龄差异。
