  • The aqueous extract of Chungsimyeonja-eum has been used to treat palpitation, anemia, chronic fatigue, hypertension, and stroke. It also possesses various pharmacological effects including hypotensive, blood circulating, sedative, anti-inflammatory, diuretic, and anti-stress activities. In the present results, the latency time of plantar test was decreased in the immobilization stress and incusion pain-induction group. However the paw withdrawal latency values were increased in the immobilization stress and incision pain-induction groups after treatment with the aqueous extract of Chungsimyeonja-eum. The c-Fos expression in the paraventricular nucleus (PVN), and 5-hydroxytryptamine (5-HT) and tryptophan hydroxylase (TPH) in the dorsal raphe were enhanced in the immobilization stress and incision pain-induction groups. However, the treatment with the aqueous extract of Chungsimyeonja-eum suppressed the immobilization stress and incision pain-induced increase of c-Fos, 5-HT, and TPH expressions. Here in this study, we have demonstrated the protective effects of Chungsimyeonja-eum on immobilization and incision pain-induced stress. The present study revealed that Chungsimyeonja-eum treatment diminishes immobilization and pain stress.

  • Heat stress negatively affects cattle productivity by reducing feed intake. In the present study, we assessed if the rumen microbiome composition of Hanwoo steers was altered by exposure to heat stress. Rumen samples were collected from four Hanwoo steers that were individually housed in climate-controlled chambers with 60% humidity and environmental temperatures of: 1) 15℃ (0-day group), 2) 35℃ for 3 days (3-day group), and 3) 35℃ for 6 days (6-day group). The total community DNA of samples was extracted, and 997,843 bacterial and 1,508,770 archaeal sequences were analyzed using next-generation sequencing. Assessment of the relative abundances revealed 15 major phyla of which Bacteroidetes was found to be the most dominant. After 3 days of heat stress exposure there were no significant changes in the rumen microbiome composition, except for a decrease in the Planctomycetes. However, after 6 days of heat stress exposure, we found that the relative abundance of fibrolytic Ruminococcaceae had decreased while that of lactate-producing Lactobacillaceae and amylolytic Prevotella and Ruminobacter had increased. The normal rumen microbiome of Hanwoo cattle was shown to be disrupted after 6 days of heat stress, which led to the decrease in fibrolytic bacteria that are sensitive to low pH and the increase in both lactate-producing and amylolytic bacteria. We have demonstrated that the microbiome composition of the rumen is affected by acute heat stress. Our findings may contribute to the development of different feeding strategies to restore heat stress-induced disruption of the rumen microbiome.

  • The purpose of this study was to assess the effects of herbs aroma on relaxation in highly stressed volunteers with heart rate variability(HRV) and SACL(stress arousal check list). 28 highly stressed volunteers participated in this study. The volunteers were examined with heart rate variability(HRV) and SACL(stress arousal check list) before and after smell herbs aroma. After smelling powder incense composed with oriental medicine herbs, mean RR, SDNN, LF, HF, TP were incresed and mean HRV, LF/HF ratio were decreased, but it was not significant. And VLF, norm HF were incresed and norm LF was decreased significantly. This results show that the powder incense composed with oriental medicine herbs effects on decresing sympathetic nervous activity and increasing parasympathetic activity and rebalancing autonomic nervous system who were under stress.
