Retrospective analysis included 316 case histories of diabetic patients treated at the Silesian Rheumatology Hospital in 1987-1988. An analysis included causes of disorders, calcium-phosphorus metabolism disturbances, lipid and purine disorders. Statistical parameters were compared with the type of diabetes mellitus, duration of the disease, sex, age and obesity. There were 10% of inflammatory rheumatic disorders (6.4% rheumatic arthritis, 1.7% of rheumatoid spondylosis and 2% of other disorders) in the analysed case histories, and 32% of degenerative disorders (19% of vertebral column joints and 12.7% of other joints). Degenerative disorders were noted more frequently in patients with diabetes mellitus type 2, treated with insulin, while spondylopathies were particularly frequent in female patients of this group. Biochemical disorders in the form of hypocalcemia and hypophosphatemia, hypertriglyceridemia, hyperuricemia, signs of lesions to the liver and kidneys were more increasing with the duration of the disease and the degree of insulin-dependence. Locomotive system disorders are not related only to primary articular lesions. They depend also on diabetic neuro-vascular complications and osteopenia. 相似文献

The 2C DNA values in 38 species and accessions of the genus Lupinus (Fabaceae) from the New World have been analysed using flow cytometry. They are representatives of North and South American
species (the Atlantic and the Andean regions). Estimated 2C DNA values ranged from 1.08 pg in L. pusillus to 2.68 pg in L. albicaulis (both from North America), that is a variation of more than 2.5-fold. The variation for North American lupins was much higher
than that for South American ones. Statistical analysis of the data resulted in a grouping that showed for North American
lupins some correlation with the length of life cycle. Discussion concerns some aspects of the evolution of the genus. 相似文献

Sequences of chloroplast gene rbcL and partial nuclear 26S rDNA were used to evaluate phylogenetic relationships of Asteropyrum. Four primary clades were recognized in Ranunculaceae, corresponding to subfamilies Hydrastidoideae, Coptidoideae, Thalictroideae,
and Ranunculoideae. Our results place Asteropyrum in Ranunculoideae, sister to the tribe Actaeeae, which includes Beesia, Cimicifuga, and Eranthis. This is supported by chromosome characters, including chromosome size and basic number, and the stainability of prophase
chromosomes and interphase nuclei. Our results do not support previous placements of Asteropyrum in either Coptidoideae or Thalictroideae. Considering its uniqueness in a few characters (e.g. simple peltate leaves, accumulating
benzylisoquinoline alkaloids, vessel elements with only typical scalariform perforation plates), we recognize Asteropyrum as a monotypic tribe of Ranunculoideae, Asteropyreae W. T. Wang et C. Y. Chang. 相似文献

灵昆岛潮间带大型底栖动物群落结构与生态位分析 总被引:11,自引:0,他引:11
2003年11月至2004年8月,在温州湾的灵昆岛东滩进行了大型底栖动物采样调查。共发现大型底栖动物33种,隶属7门8纲21科。主要为软体动物、节肢动物和环节动物多毛类,其中高潮带25种,中潮带30种,低潮带14种。通过对不同季节不同潮带的大型底栖动物密度数据进行成对t检验分析,结果认为各潮带的大型底栖动物密度分布有明显差异,而大型底栖动物密度的季节变化不明显。对定量取样中获得的21个物种以Shannon-W iener指数为基础进行了生态位宽度测定,以P ianka重叠指数为基础进行了生态位重叠值分析,结果表明日本沙蚕(N ereis jap on ica)、纽虫和线虫的生态位较宽,均为2.80以上,它们之间的生态重叠值也较高,均为0.90以上。以密度数据四次开方为基础,利用欧氏距离进行群落物种的系统聚类分析,结果表明21个物种可以分为三大类,即潮间带广布种、中高潮带常见种、狭布种和偶见种,通过非度量多维标度排序分析也支持以上结果。3类物种的生态位重叠值均有不同的表现,与物种的分布与数量相关。研究表明,物种生态宽度、物种之间的生态位重叠值与物种的分布与数量密切相关,反映了大型底栖动物群落中各物种对生境资源的利用能力的强弱。 相似文献
