The inhibitory effect of dl-puerol A as but-2-enolide isolated from Sophora japonica was investigated on copper ion-induced protein oxidative modification in vitro. It inhibited copper-induced protein oxidative modification. However, its inhibitory effect was a little weaker than that of $dl-{\alpha}-tocopherol$ as an antioxidant. The results demonstrated that dl-puerol A, one of but-2-enolides, might be of use in the oxidative stress.
Functional bioactivity of Polygonatum species
Motohashi, Noboru,Zhang, Guo-Wen,Shirataki, Yoshiaki Kyung Hee Oriental Medicine Research Center 2003 Oriental pharmacy and experimental medicine Vol.3 No.4
The genus Polygonatum species belongs to the family Liliaceae which is widely distributed over areas of the north temperature zone. There are about forty more plants of Polygonatum species in the world widely distributed in eastern Europe and south east Asia. The plants of Polygonatum species have been used not only as ornamental plants but also for their medicinal values. This article is concerned with the specific properties and flavour of the drug and its history as a medicine, showing the main functional components of Polygonatum species of flavonoids, steroidal glycosides, and saccharides.
Phytochemical isoflavones against diabetic foot bacteria

Wound swabs and pus samples were collected from diabetic foot ulcers, and control pus samples from non-diabetic cases. In 144 diabetic cases screened, Pseudomonas aeruginosa was isolated from 78 cases, in which 10.59% of the isolates were multidrug resistant (MDR), whereas the 60 control cases were not MDR. The isolated bacteria were decreasingly resistant to 6 clinically administrated antimicrobics such as ceftazidime, gentamicin, ciprofloxacin, tobramycin, piperacillin and amikacin. Therefore, it is demanded that new and more effective antimicrobials of phytochemical origins are sought after. Among 11 isoflavones (YS11-YS21) isolated from Sophora and Euchresta (Leguminosae; pea plant family), 2 (YS19 and YS21) prominently exhibited the high antibacterial activity both in vitro and in vivo. By the preliminary results, the object of this paper is to evaluate the in vitro antibacterial effect of YS19 and YS21 on the clinically isolated bactera of Ps. Aeruginosa in hospitals. All the isolates were sensitive to YS19 and YS21 and for both, minimum inhibitory concentration (MIC) values ranged from $2\;to\;50\;{\mu}g/mL$. The $MIC_{90}$ values of YS19 and YS21 were $50\;{\mu}g/mL$. It is suggested that these isoflavones might consist a basis phytochemical prevention and therapy for diabetic foot infections caused by pseudomonads.
Evaluation of Force Delays on the Operation of Haptic Sense

Recently,Virtual Reality (VR) technology has developed quickly,together with research conducted on various elemental and related technologies and research in various fields of its application.We experimented about the delay.The haptic media is very sensitive to the network delay and its jitter and packet loss.The AHP is one of methods to evaluate physical phenomena as correctness of the human sensation. In consequence of its application to the present experiment, it was made clear that the haptic media could be estimated from the delay times. An experiment was conducted using the AHP technique into the effect of feedback force delay on users by using the normal feedback force of a spring as an experimental model. The experiments in this study showed that there is a time delay threshold of 4 ms or more. In addition, when a thorough experiment was conducted in this range, it was found that humans could perceive a variation (difference threshold) in the delay of feedback force for a virtual spring that is between 4 ms and 5 ms.
