| 1 | Experimental and numerical studies on new multi-dimensional earthquake isolation and mitigation device:Horizontal properties显示文摘Earthquake is a complex multi-dimensional excitation. Counter-measures of such multi-dimensional excitation on many critical structures,such as long-span structures and high-rise buildings,must be taken into account to avert the structural failure. Many types of earthquake mitigation or isolation devices for mitigating earthquake-induced effects in the horizontal direction have been proposed and applied to real applications. However,study on multi-dimensional earthquake isolation and mitigation devices for structures has been received much less attention. In this paper,a new multi-dimensional earthquake isolation and mitigation device was developed and tested. Effects of excitation frequency and environmental temperature on horizontal properties of this device were considered. At the same time,fatigue properties of the device under different amplitude horizontal excitations were also studied experimentally. The equivalent standard solid model which can effectively describe the effect of frequency and temperature on the horizontal properties of the device was proposed and verified. From the experimental results,it may be concluded that the multi-dimensional earthquake isolation and mitigation device owns fine energy dissipation and fatigue resistance capabilities. | XU ZhaoDong1, ZENG Xiao2, HUANG XingHuai1 & LU LiHeng1 1 RC&PC Key Laboratory of MOE, Southeast University, Nanjing 210096, China 2 Huaxin Past & Telecom Consulting and Designing Institute Co.

| 3 | Antitussive activity of Triclisia dictyophylla of the family Menispermecae显示文摘Objective:To verify through a scientific mean the therapeutic use of the plant as an anti-tussive agent,by traditional medicine healers and also aid in the search for new drugs developments from plants.Methods:The roots of Triclisia dictyophylla were investigated for their antitussive properties.The plant was uprooted in the month of June 2003 at Igbodo,Delta State,Nigeria and was taken to the university of Nigeria Nsukka for taxonomy. The roots were chopped,ground and immersed in pure drinking water for 24 hours.After filtration, extraction was carried out using a Rotary evaporator,preliminary phytochemistry and acute toxicity studies were carried out.Antitussive study was carried out using a total of 42 young rats of average weight of 72.2 g.The rats were housed in standard animal house of the university and were allowed access to feeds and water but, were fasted for 12 hours prior to commencement of experiment.Specific and appropriate dosage of the crude extract and Codeine re - dissolved in water were administered orally 30 minutes prior to induction of cough. Cough was induced by exposing the animals to Sulphure dioxide gas for 3- minutes.Coughing was taken as number of Head-nods per minute,Stethoscope aided audible sounds and,or tears secretion.Percentage cough inhibition for crude extract and,or Codeine treated rats were compared with reference to control animals.Results were subjected to statistical analysis using SPSS 13.0.Results:A 10.2%extraction yield was got from a starting root initial weight of 320 g.The preliminary phytochemistry of the aqueous root extract revealed the presence of alkaloids,saponins,flavonoids,proteins,reducing sugars,steroids,resins fats/oils and glycosides. The Median lethal dose(LD_(50)) based on Lorke's 1983 method was 548 mg/kg The aqueous root extract at concentrations of 10 mg/kg,50 mg/kg,100 mg/kg and 200 mg/kg orally administered,inhibited cough in rats induced by sulphure dioxide gas by 16.67%,33.33%,50.00%and 83.33%respectively.While Codeine phosphate,a standard antitussive agent,at oral concentrations of 10 mg/kg and 20 mg/kg inhibited cough in rats induced by sulphure dioxide gas by 33.33%and 60.67%respectively.Conclusion:Earlier works by some authors had led to isolation of Morhinian Alkaloids from Triclisia dictyophylla thus most probably linking its mechanism of antitussive activity to that likable of Morphine.This study justifies the use of the plant in treatment of cough by Traditional Medicine Healers. | Azikiwe CCA Unekwe PC Amazu LU Luechai Srigernyaung Ezeani MC Nwosu PJC Ajugwo A | 2009 | Asian Pacific Journal of Tropical Medicine2009，2，4： | 2 |
