DanHong Injection inhibits the development of primary abdominal aortic aneurysms in apoE knockout mice

Clinical observations indicate that DanHong Injection （DHI） can increase blood flow and reduce various syndromes in patients with cardiovascular disease. How- ever, it still needs to define the function of DHI and the involved mechanisms in details, such as the protective effect on the development of primary abdominal aortic aneurysms （AAAs）. In this study, we determined whether DHI is able to inhibit AAA in apoE knockout （apoE-/-） mice. Thirty apoE-/- male mice on high-fat diet （0.5 % cholesterol, 21% fat） were randomly divided into two groups and received i.p. injection of saline （100 μL/day） and DHI （100 μL/day）, respectively, for 16 weeks. At the end of experiment, we determined the development of atherosclerosis in en face aorta and aneurysms,pathological morphology of arterial wall, and serum lipid levels. We also determined the expression of monocyte chemoattractant protein-1 （MCP-1）, MMP-2, and MMP-9 mRNA in aortic wall using real-time RT-PCR. Our results indicated that high-fat diet induced the development of AAAs in apoE-/- mice, but the induction was totally blocked by DHI （P 〈 0.01）. The result of staining of abdominal aortic cross sections showed that DHI main- tained the collagen content in arterial wall, thereby pre- venting the animals from the development of AAA. Although DHI had little effect on serum total- and LDL- cholesterol levels, it reduced the expression of MCP-1, MMP-2, and MMP-9 mRNA in aortic wall （P 〈 0.01）. Taken together, our study suggests that DHI can inhibit the high-fat diet-induced AAA formation. The inhibitory effects may be related to the maintenance of the collagen content and inhibition of expression of AAA-related genes. Our study may suggest a new application of DHI in clinics.     

Polymorphism,taxonomy and host plant associations in Alebra leafhoppers (Homoptera: Cicadellidae: Typhlocybinae)

The taxonomy of a complex of morphologically similar Alebra species is clarified, and the number of adult colour pattern morphs of each in Britain, and their host plant associations, established. Morphological characters are figured for the identification of the four species now recognized, including two that are associated with different species of deciduous oaks and which were previously regarded as colour pattern morphs of A. albostriella. Three nymphal colour pattern morphs are described within the A. albostriella sibling species, two of which are shared, thus supplying further evidence for their close relationship. A key is given for the identification of the species and adult morphs of Alebra in Britain.

The cuticle of two species of Bothrodendron [Lycopsida: Lepidodendrales]

Summary

The variability of four characters commonly used in the separation of species of Limnodrilus has been described, and their relative values assessed. The number of setae per bundle is useless as a specific character; the shape of the setae can serve to distinguish only a single species and the length: breadth ratio of the penial sheath is more useful as an additional or confirmatory character. The shape of the penial sheath proved to be the most important character, but even this was not completely reliable, and it is concluded that several characters must be used in the identification of species of Limnodrilus. It is suggested that structures other than the cuticular derivatives should be examined and that a similar study be carried out on North American species.
