An Ideal Raw-radish Therapy for Allergic Rhinitis

[Objectives] To explore a kind of simple and effective dietotherapy for allergic rhinitis( AR). [Methods]48 patients with AR were hospitalized and randomly assigned to raw-radish treatment group( 36 patients) or placebo group( 12 patients). Every patient took about 150 g raw radish( experimental group) or cooked radish( placebo group) one time or separately a day. [Results]By continuously taking raw radish for fifteen days,the total cure rate reached 80. 6% and total valid rate reached 94. 4%,with the valid rate 100% for persistent AR and 66. 7% for intermittent AR. But cooked radish( placebo) was invalid to AR. Presumably the wonder efficacy of raw radish may be related with isothiocyanates in radish. Since isothiocyanates are susceptible to hydrolysis by cooking,so radish must be eaten raw. [Conclusions] Raw radish therapy works wonders for AR,which may be more effective,safer,cheaper and simpler method for prevention and treatment of AR at present.

Effects of enhanced UV-B radiation on fitness of an alpine species Cerastium glomeratum Thuill

Aims Information about how species respond to extreme environments,such as high UV-B radiation,is very useful in estimating natural ecosystem structure and functions in alpine areas.Our aim is to examine the effect of enhanced UV-B radiation on the fitness of an alpine meadow annual species on Qinghai-Tibet Plateau.Methods Plants of Cerastium glomeratum Thuill.were exposed to ambient(control)or ambient plus supplemental UV-B radiation(enhanced),simulating a 9%ozone depletion over Gannan,China(102
53#E,34
55#N,2900 m in altitude),up to leaf senescence and fruit maturation.Plant height,flower phenology,biomass allocation and reproductive parameters of the species were measured.Important findings Plant height in C.glomeratum was reduced by enhanced UV-B radiation at early growth stages and compensated with ongoing development.Fruit biomass,aboveground biomass,total biomass and reproductive effort(fruit dry mass/aboveground biomass)were not affected by enhanced UV-B radiation,but a significant increase in root/shoot ratio was found.Enhanced UV-B radiation delayed onset of flowering by 1 day and shortened duration of flowering by 5 days in C.glomeratum.But because of the long period of flowering time(83–88 days),this did not make any significant effect on flower number,seed number,pollination success(number of seeds per fruit)or reproductive success(fruit to flower ratio)in C.glomeratum.Enhanced UV-B radiation had no effect on seed germination and seed mass either.And the high production and low germination rate of the seed might be the strategy of C.glomeratum to survive the extreme environments on alpine meadow.All these results showed that C.glomeratum was tolerant to enhanced UV-B radiation.
