The exotic shrub glossy buckthorn (Frangula alnus) is a great concern among forest managers because it invades both open and shaded environments. To evaluate if buckthorn grows similarly across light environments, and if adopting different shapes contributes to an efficient use of light, we compared buckthorns growing in an open field and in the understory of a mature hybrid poplar plantation. ...

It was demonstrated that an extract from the pharmacopoeial raw material bilberry fruit (Fructus Myrtilli) co-administered with selected antibiotics: cefuroxime, cefoperazone and doxycycline, positively affects the survival of mouse thymocytes in cultures with hydrocortisone (cytotoxicity test), increases the count of splenocytes forming spontaneous rosettes (E-rosette test) and increases the a...

The present investigation was undertaken to evaluate the healing efficacy of lyophilized aqueous leaf extract of Sea buckthorn (Hippophae rhamnoides L., family Elaeagnaceae) (SBT) and to explore its possible mechanism of action on experimental burn wounds in rats. The SBT extract, at various concentrations, was applied topically, twice daily for 7 days. Treatment with silver sulfadiazine (SSD) ...

Dry eye is a common condition that can severely impair the quality of life. We aimed to find out whether oral sea buckthorn (SB) oil, containing (n-3) and (n-6) fatty acids and antioxidants, affects dry eye. In this double-blind, randomized, parallel trial, 20- to 75-y-old women and men experiencing dry eye symptoms consumed 2 g of SB or placebo oil daily for 3 mo from fall to winter. One hundr...

This study aims to evaluate the effect of different afforestation models on soil microbial composition in the Loess Plateau in China. In particular, we determined soil physicochemical properties, enzyme activities, and microbial community structures in the top 0 cm to 10 cm soil underneath a pure Hippophae rhamnoides (SS) stand and three mixed stands, namely, H. rhamnoides and Robinia pseucdoac...

BACKGROUND Vaginal atrophy, the thinning and drying of vaginal mucosa, is associated with menopause. The standard estrogen treatment is not suitable for all women. OBJECTIVE To investigate the effects of oral sea buckthorn (SB) oil supplementation on vaginal atrophy.

Effect of pre-irradiation administration of different doses of RH-3, the herbal preparation of an Indian medicinal plant Hippophae rhamnoides, 30 min before 10 Gy whole body gamma irradiation was studied. Doses between 25 to 35 mg/kg body wt. were found to render > 80 % survival in mice. In order to investigate whether RH-3 protected against radiation induced genotoxicity, mice were administere...

The objective of this study was to develop a pharmaceutical O/W emulsion containing plant-derived polyphenol extracts and evaluate its stability and antioxidant activity. O/W emulsions were prepared using ionic surfactant polysorbate 80 (Tween 80®). The odorwas adjusted with few drops of blue sea fragrance. DPPH (1,1-diphenyl-2-picrylhydrazyl) assay was used to evaluate the antioxidant activity...
