Anti-inflammatory Effects of Sanguisorbae Radix on Contact Dermatitis Induced by Dinitrofluorobenzene in Mice

Objective:To investigate the anti-inflammatory effects of Sanguisorbae Radix on contact dermatitis(CD).Methods:Mice were sensitized by painting 30μL of 1-fluoro-2,4-dinitrofluorobenzene(DNFB)onto each ear for 3 days.Four days later,mice were challenged by painting with 50μL of DNFB onto the shaved dorsum every 2 days.Sanguisorbae Radix methanol extract(MESR)was applied onto the shaved dorsum every 2 days.The effects of MESR on skin thickness,skin weights,histopathological changes,skin lesions and cytokine production in DNFB-induced CD mice were investigated,as well as its effects on body weights and spleen/body weight ratio.Results:Topical application of MESR effectively inhibited enlargement of skin thickness and weight(P<0.05).MESR treatment also inhibited hyperplasia,spongiosis and immune cell infiltration induced by DNFB in inflamed tissues and improved lesions on dorsum skin in CD mice.Moreover,treatment with MESR suppressed the increase in the levels of tumor necrosis factor α(TNF-α,P<0.01)and interferonγ(IFN-γ,P<0.05),respectively.Finally,MESR had no effect on body weight gain or spleen/body weight ratio.Conclusion:These data suggest that MESR acts as an anti-inflammatory agent that decreases the production of TNF-α and IFN-γ,resulting in reductions of skin lesions and histopathological changes in inflamed skin tissues.

Marker-Assisted Introgression of Quantitative Resistance Gene pi21 Confers Broad Spectrum Resistance to Rice Blast

The quantitative resistance gene pi21 from Sensho was introgressed to an indica breeding line IR63307-4B-13-2,a pyramiding line IRBB4/5/13/21,and a tropical japonica line Kinandang Patong by marker-assisted backcrossing.A total of 192 improved lines at the BC4F3 and BC4F4 generations were developed and confirmed to have the gene introgression via genotyping using a pi21-specific InDel marker.Thirteen randomly selected improved lines,representing all the three genetic backgrounds,demonstrated resistance against leaf blast composites in the field and a broader spectrum resistance against individual isolates compared to the recurrent parents in the glasshouse.Specifically,the tested lines exhibited pi21-acquired resistance against 11 leaf blast isolates that elicited susceptible reactions from the recurrent parents.All the tested lines maintained a comparative heading date,and similar or improved panicle length,number of primary branches per panicle and number of total grains per panicle relative to the recurrent parents.The physical grain characteristics of the recurrent parents were also maintained in the 13 lines tested,although variability in the amylose content and chalkiness degree was observed.The successful marker-assisted introgression of pi21 in diverse genetic backgrounds and the resulting broader spectrum resistance of improved lines against leaf blast indicate the potential of pi21 for deployment in cultivars grown across other rice growing regions in Asia.
