We investigated the effects of tissue-cultured mountain ginseng extract （TMGE） on male patients with erectile dysfunction （ED）. A double-blind, placebo-controlled study was conducted with 143 patients experiencing ED. Over the course of 8 weeks, one group took 1 000 mg of TMGE twice a day, and the other group took 1 000 mg of placebo twice a day. The effects of the TMGE and the placebo were analyzed using the Korean version of the International Index of Erectile Function （IIEF） questionnaire. A total of 86 patients completed 8 weeks of treatment. The scores on the five domains of the IIEF after medication were significantly higher than the baseline scores in the group treated with TMGE （P 〈 0.05）, whereas no significant improvement was observed in the placebo group （P 〉 0.05）. Erectile function and overall satisfaction scores after medication were significantly higher in the TMGE group than in the placebo group （P 〈 0.05）. Erectile function of patients in the TMGE-treated group significantly improved, suggesting that TMGE could be utilized for improving erectile function in male patients.展开更多

After typhoon passed through, fresh banana seedlings are often required. That is a problem for companies on culturing banana seedling, since culturing banana seedlings takes about four months and typhoon cannot be predicted so early. If the growth of banana seedlings can be slowed down and the seedlings can be cultured in nursery shed for more time, this problem will be solved. In this research, seven treatments (paclobutrazol, diniconazole, paclobutrazol + brassins, paclobutrazol + diethyl aminoethyl hexanoate, diniconazole + brassins, diniconazole + diethyl aminoethyl hexanoate, chlormequat chloride) were performed on banana seedlings and the growth was measured. Results showed that in all of the treatments, the values of plant height, leaf length, pseudostem diameters, root length, root weight, root volume, fresh weight of above-ground tissues and fresh weight of seedlings were significantly less than those corresponding values of control. The reducing powers of roots of seedlings sprayed with paclobutrazol and paclobutrazol + diethyl aminoethyl hexanoate were remarkably higher than those of seedlings treated with water. Total chlorophyll content in leaves of seedlings sprayed with paclobutrazol was remarkably higher than that of seedlings treated with water. Total chlorophyll contents in leaves of seedlings treated with paclobutrazol + diethyl aminoethyl hexanoate and chlormequat chloride were lower than those of control. For delaying the growth of banana seedlings, chlormequat chloride was the best among the seven treatments. The mechanism might be that the enzyme CPP-synthase in seedlings was inhibited by chlormequat chloride.展开更多
