Description:

Eleutheroside E(EE) has anti-inflammatory and protective effects in ischemia heart, the beneficial effect of EE may provide an effective and powerful strategy to alleviate behavioral alterations induced by sleep deprivation, it may influence to immune-enhancing through increasing the physical endurance capacity and immune cell activation. EE significantly decreases the inflammatory cell infiltration, pannus formation, cartilage damage, bone erosion of CIA mice, the generation of TNF-α and IL-6, the metabolism of drugs metabolized via CYP2C9 and CYP2E1.

Immune-enhancing effect of Acanthopanax Koreanum and its component, Eleutheroside E on the protein-energy malnourished C57bl/6 mice    

Acanthopanax Koreanum stem (AK) has been used in Korea as a tonic and sedative as well as a drug with ginseng like activities. 

METHODS AND RESULTS:

The purpose of our present study was to investigate the effects of AK extract (AKE) and Eleutheroside E, major component of AKE on an exacerbated immune function through utilization of protein-energy malnutrition (PEM) diet by using forced swimming test (FST). The immobility time were significantly decreased in the AKE or Eleutheroside E-administrated group compared with the control group on the FST (P compared with unstimulated splenocytes but not interleukin (IL)-4. Eleutheroside E also significantly increased the IFN-\gamma production but not IL-2 and IL-4 in T cell line, MOLT-4 cells. 

CONCLUSIONS:

These results suggest that AKE and Eleutheroside E may influence to immune-enhancing through increasing the physical endurance capacity and immune cell activation.

The effect of Eleutheroside E on behavioral alterations in murine sleep deprivation stress model.   

Eleutheroside E (EE), a principal component of Eleutherococcus senticosus, has been reported to have anti-inflammatory and protective effects in ischemia heart etc. However, whether it can mitigate behavioral alterations induced by sleep deprivation, has not yet been elucidated. Numerous studies have demonstrated that memory deficits induced by sleep deprivation in experimental animals can be used as a model of behavioral alterations. The present study investigated the effect of EE, on cognitive performances and biochemical parameters of sleep-deprived mice. 

METHODS AND RESULTS:

Animals were repeatedly treated with saline, 10 or 50mg/kg EE and sleep-deprived for 72 h by the multiple platform method. Briefly, groups of 5-6 mice were placed in water tanks (45 × 34 × 17 cm), containing 12 platforms (3 cm in diameter) each, surrounded by water up to 1cm beneath the surface or kept in their home cage. After sleep deprivation, mice showed significant behavioral impairment as evident by reduced latency entering into a dark chamber, locomotion and correctly rate in Y maze, and increased monoamines in hippocampus. However, repeated treatment with EE restored these behavioral and biochemical alterations in mice. 

CONCLUSIONS:

In conclusion, the beneficial effect of EE may provide an effective and powerful strategy to alleviate behavioral alterations induced by sleep deprivation.
