6. Effects of the mulberry leaf extract on depression-like behavior in mice
Journal of International Pharmaceutical Research 2020;47(4):269-275
Objective: To investigate the antidepressant effect and mechanism of the extract of mulberry leaf(EML). Methods: Male BALB/c mice were randomly assigned to receive EML(100, 200 and 400 mg/kg)or vehicle for 7 days or single administration by intragastric(ig)route. The effect of EML on spontaneous activity in mice was evaluated using the open field test. The anti-depressant activity of EML was evaluated using the tail suspension test and forced swimming test. After single ig administration of EML (100, 200 and 400 mg/kg), the effects of EML on the function central monoaminergic nervous system were evaluated using the 5-hydroxy-L-tryptophan(5-HTP)induced head-twitch test, yohimbine toxicity potentiation test and reserpine test in mice. Results: In the behavioral despair model, the continuous administration of EML(100 mg/kg)for 7 days significantly reduced the immobility time in the tail suspension test and forced swimming test. Compared with the vehicle group, the inhibitory rates of immobility time were 35.5% and 41%(P<0.05, P<0.01)in the tail suspension test and forced swimming test, respectively. The single treatment with EML(400 mg/kg)also significantly reduced the immobility time in the tail suspension and forced swimming test, and the inhibitory rates of immobility time were 29.1% and 35.3%, respectively(P<0.05). The results of spontaneous activity test showed that EML had no excitatory or inhibitory effect on the central nervous system in mice. In the 5-HTP induced head-twitch test in mice, the single treatment with EML(100 mg/kg)significantly increased the number of head-twitches in mice. In the yohimbine toxicity potentiation test, the single treatment with EML(100, 200 and 400 mg/kg)had no significant effect on the mortality rate in yohimbin-treated mice. In the reserpine test, compared with the model group, the single treatment with EML(400 mg/kg)antagonized reserpine induced ptosis (P<0.05)and had no significant effect on the decrease in rectal temperature and akinesia. Conclusion: EML showed antidepressant effect, and the action mechanism was likely related to the enhancement of the function of serotonergic nervous system.

Objective To investigate the effects of Irbesartan on endothelial function and autonomic nervous system activity of patients with essential hypertension. Methods The endothelium dependent flow mediated dilatation (F-MD) and the endothelium independent nitroglycerin mediated dilatation (NTG-MD) were evaluated by the brachial ultrasound examination. Time-domain indices of heart rate variability (HRV) were measured by 24 h ambulatory electrocardiogram. The changes of blood lipoproteins, blood glucose, insulin levels, endothelial function and heart rate variability in 60 patients with mild-moderate essential hypertension and 20 healthy controls were compared, and the effects of different antihypertensive agents (AT1 receptor blocker and diuretic) for 8-week treatment were observed. Results Endothelial dysfunction and abnormal autonomic nervous activity were observed in patients with mild-moderate essential hypertension as follow: mildly decreased total HRV and mildly increased 24-hour average heart rate, significantly decreased parasympathetic tone-rMSSD and PNN50, obviously lowered endothelium dependent F-MD. The postprandial insulin level and insulin/glucose ratio of patients with hypertension was significantly higher than that of healthy controls. The decreased blood pressure level caused by AT1 receptor blocker (Irbesartan) and diuretic (Indapamide) was similar. Irbesartan for 8-week therapy resulted in a significant improvement of the endothelium dependent F-MD and insulin resistence, the increase of vagal nervous activity and the decrease of 24-hour average heart rate, but Indapamide presented no such effects. Conclusion This study suggested that patients with mild-moderate essential hypertension have significantly abnormal endothelial function and autonomic nervous activity, and the beneficial effect of Irbesartan is associated with an improvement of insulin resistence and heart rate variability, not with the decrease of blood pressure level.

Objective To investigate the effects of S-adenosylmethionine (SAM) on ethanol-induced liver injury in rats. Methods 48 female SD rats were randomly divided into 4 groups as control, model, small and large dose SAM groups. Except control group, all rats were fed high fat-containing diet plus ethanol and fish oil gavage for 8 weeks. SAM was administered by intraperitioneal injection after 4 weeks of exposure to ethanol. Plasma total homocysteine (tHcy), serum aminotransferase activity (ALT), liver malondialdehyde (MDA), glutathione (GSH) contents were assayed, and expression of TNF-? was detected by immunohistochemistry, and liver histology was also examined. Results Compared with control group, model group rats developed marked liver damage, accompanied by an increase of tHcy, ALT, and MDA levels, but a decrease of GSH levels (P0.05). Conclusion SAM prevents alcohol-induced liver injury in rats by reducing liver lipid peroxidation, together with down-regalation of expression of TNF-?. SAM does not affect the plasma total homocysteine levels.
