Effects of Foeniculum vulgare L. extract on anxiety-like behaviors in ovariectomized mice

Background and Aims: Anxiety is one of the symptoms of menopause, which is due to stopping of ovarian activity. The aim of this study was to investigate the effect of Foeniculum vulgare L. extract on anxiety-like behaviors in ovariectomized mice.Methods: Eighty female mice weighing 25-30 g and aged 6-8 weeks were divided into 10 groups of eight each, controls: the group without ovariectomy given distilled water, positive controls: the ovariectomized group receiving 40 µg/kg of estradiol valerate, the groups without ovariectomy given F. vulgare extract by gavage at 200, 500, and 750 mg/kg, the ovariectomized group given distilled water, the ovariectomized groups given F. vulgare extract at 200, 500, and 750 mg/kg, and the ovariectomized group given diazepam at 1 mg/kg. Elevated plus maze (EPM) and open field were used to investigate anxiety in mice. The level of malondialdehyde (MDA) and total antioxidant capacity (TAC) of the brain and serum were also measured. Results: In ovariectomized mice, the number of entries to the closed arms of EPM was significantly increased compared with control group (P<0.05). Treatment of ovariectomized mice with 500 and 750 mg/kg of the extract significantly increased the number of entries to the open arms and significantly decreased the number of entries to the closed arms of EPM (P<0.05). The time spent in the center and the crossing squares in the open field significantly decreased in ovariectomized mice compared with control group and treatment with estradiol significantly increased them (P<0.05). In ovariectomized mice, serum and brain MDA levels significantly increased and their TAC significantly decreased compared with control group. Different doses of extract, estradiol and diazepam significantly reduced MDA levels and increased TAC in both brain and serum (P<0.05).Conclusion: vulgare extract may ameliorate the symptoms of anxiety in ovariectomized mice by reducing oxidative stress

Effect of White Tea (Camellia sinensis) Extract on Skin Wound Healing Process in Rats

BACKGROUND White tea (Camellia sinensis) has anti-inflammatory and antioxidant properties and a protective effect against wrinkles, sunburn and UV damages on the skin. Thus, we aimed to evaluate the effect of white tea extract on the healing process of skin wounds in rats. METHODS This study was done in the Research Center of Shahrekord University of Medical Sciences, Shahrekord, Iran in 2019. Excisional skin wounds were created on five groups of healthy male Wistar rats (200-250 g, n=21) including control group, Eucerin-treated group, white tea 5% ointment (Eucerin) treated group, gel-treated group, white tea 5% gel treated group. Treatment was begun on day 1 and repeated every day at the same time until day 15. Pathologic samples were taken on days 4, 7 and 15 for histopathological examinations. Kruskal-Wallis test was used to analyze data by SPSS. Statistical significance was defined as P<0.05. RESULTS Wound closure rate of control group was more than other groups on day 4 (P<0.05). On day 7, reepithelisation and granulation tissue of control group were more than white tea 5% ointment-treated and its inflammation was less than others (P<0.05). Neo-vascularization of white tea 5% ointment-treated group was more than control group on days 4 and 15 (P<0.05). On day 4, intact mast cells of control group were more than white tea treated groups (P<0.05). Degranulated mast cells of white tea 5% gel treated group was significantly (P<0.05) more than control group on days 4 and 15. CONCLUSION Five percent white tea extract could not help the skin wound healing process
