Yersinia enterocolitica, which causes yersiniosis, is a bacterium that produces biofilms effectively. The inhibition of biofilm formation provides a method for preventing infections with Y. enterocolitica. In this study, the inhibitory activity of Y. enterocolitica biofilm formation was investigated in a library of 140 edible plant methanol extracts including forest products. It was identified that the biofilm formation could be inhibited by 12 extracts of plants, Agastachis Herba, Agrimoniae Herba, Diospyros kaki leaves, Elsholtziae Herba, Ginkgonis Semen, Lycopi Herba, Melonis Pedicellus, Menthae Herba, Mori Radicis Cortex, Polygoni Multiflori Radix, Prunellae Spica, and Schizonepetae Spica. After changing the solvent to ethanol and water, the greatest inhibition of biofilm formation was produced by a 50% ethanol extract of Polygoni Multiflori Radix. A method to effectively prevent yersiniosis can be developed using the edible plant extracts identified in this study.

Streptococcus mutans causes oral diseases, including tooth decay, by producing a biofilm called plaque. Therefore, inhibition of biofilm formation is essential for maintaining oral health. Plants produce a variety of secondary metabolites, which act as starting sources for the discovery of new bioactive chemicals that inhibit biofilm formation of S. mutans. Previous studies have reported on chemicals with antibiotic activity for the inhibition of biofilm formation by S. mutans. In this study, nine plant extracts from Melonis Pedicellus, Agastachis Herba, Mori Cortex Radicis, Diospyros kaki leaves, Agrimoniae Herba, Polygoni Multiflori Radix, Lycopi Herba, Elsholtziae Herba, and Schizonepetae Spica were screened for the inhibition of biofilm formation from a plant extract library. The water-soluble compounds of the extracts did not affect cell growth but selectively inhibited biofilm formation. These results suggest that the selected plant extracts constitute novel biofilm formation inhibitors, with a novel biological mechanism, for improving oral hygiene.

CheonghunHwadam-tang(CHT) have been used in oriental medicine for many centuries as a therapeutic agent of vertigo by wind, fire and phlegm. CHTS was CHT adding Schizonepetae Herba. The effects of CHTS on the cerebral blood flow and blood pressure is not known. The purpose of this Study was to investigate effects of CHTS on the regional cerebral blood flow(rCBF) and mean arterial blood pressure(BP), action-mechanism of CHTS-induced changed-rCBF and BP. The changes of rCBF and BP was determinated by Laser-Doppler Flowmetry(LDF). The results were as follows ; CHTS extract was increased significantly rCBF in a dose-dependent, but was not changed BP compared with CHTS non-treated group. Pretreatment with propranolol, indomethacin and methylene blue were inhibited CHTS induced increase of rCBF, propranolol(all CHTS-treated group) and indomethacin(CHTS 0.01 mg/kg) of them were significantly decreased. Pretreatment with propranonol and indomethacin were inhibited CHTS induced increase of BP, but pretreated with methylene blue was significantly accelerated BP in high dosage. This results suggest that CHTS increased rCBF by dilating pial arterial diameter and the action of CHTS is also mediated by adrenergic β -receptor and cyclooxygenase.
