Aim： To conduct a double-blind, placebo-controlled randomized and dose-ranging study to evaluate the safety and efficacy of the extract of Ganoderma lucidum （G. lucidum） in men with lower urinary tract symptoms （LUTS）. Methods： We enrolled male volunteers （〉 50 years） with an International Prostate Symptom Score （IPSS; questions 1-7）〉 5 and a prostate-specific antigen （PSA） value 〈 4 ng/mL. Volunteers were randomized into groups of placebo （n = 12）, G. lucidum of 0.6 mg （n = 12）, 6 mg （n = 12） or 60 mg （n = 14）, administered once daily. Efficacy was measured as a change from baseline in IPSS and the peak urine flow rate （Qmax）. Prostate volume and residual urine were estimated by ultrasonography, and blood tests, including PSA levels, were measured at baseline and at the end of the treatment. Results： The overall administration was well tolerated, with no major adverse effects. Statistical significances in the magnitude of changes between the experimental groups were observed at weeks 4 and 8. No changes were observed with respect to Qmax, residual urine, prostate volume or PSA levels. Conclusion： The extract of G. lucidum was well tolerated and an improvement in IPSS was observed. The recommended dose of the extract of G. lucidum is 6 mg in men with LUTS.

Aim： To evaluate the safety and efficacy of an extract of Ganoderma lucidum that shows the strongest 5α-reductase inhibitory activity among the extracts of 19 edible and medicinal mushrooms by a double-blind, placebo-controlled, randomized and dose-ranging study in men with lower urinary tract symptoms （LUTS）. Methods： In this trial, we randomly assigned 88 men over the age of 49 years who had slight-to-moderate LUTS to 12 weeks of treatment with G. lucidum extract （6 mg once a day） or placebo. The primary outcome measures were changes in the International Prostate Symptom Score （IPSS） and variables of uroflowmetry. Secondary outcome measures included changes in prostate size, residual urinary volume after voiding, laboratory values and the reported adverse effects. Results： G. lucidum was effective and significantly superior to placebo for improving total IPSS with 2.1 points decreasing at the end of treatment （mean difference, -1.18 points; 95% confidence interval, -1.74 to -0.62; P 〈 0.0001）. No changes were observed with respect to quality of life scores, peak urinary flow, mean urinary flow, residual urine, prostate volume, serum prostate-specific antigen or testosterone levels. Overall treatment was well tolerated with no severe adverse effects. Conclusion： The extract of G. lucidum was well tolerated and improved IPSS scores. These results encouraged a further, large-scale evaluation of phytotherapy for a long duration using the extract of G. lucidum on men with LUTS.

Planning Strategic Sustainable Development in Malaysia by Incorporating the Concept of Low Carbon Society

Journal of Civil Engineering and Architecture 2013年第9期7卷 1164-1176页

Malaysia has undergone rapid urbanization and economic growth for past decades and is expected to continue to have an average economic grow at 5%-6% per annum in the next five years. This phenomenon of growth and pursuit of socio-economic progress has great impact not only on the economy but also on community life style and environment. The concept of sustainable development was adopted by Malaysia government as early as mid 1990s to address some of the emerging environmental issues and more specifically on climate change issues recently. Malaysia government announced a commitment of voluntary 40% reduction in CO2 emission intensity by 2020 during the Conference of Party （COP15） meeting in Copenhagen in 2009. In parallel to this commitment of CO2 emission reduction, the concept of sustainable development in urban planning should incorporate a more comprehensive and quantitative approach in the preparation of development plan as well as in exercising the routine development control practice at the local planning authority. This paper prepares a quantitative scenario study on the establishment of low carbon society in Iskandar Malaysia.
