Effect of morin, a flavonoid against DOCA-salt hypertensive rats: a dose dependent study.
    Asian Pacific journal of tropical biomedicine, 2012, Volume: 2, Issue:6

    To determine the protective effect of morin, a flavonoid against deoxycorticosterone acetate (DOCA)-salt induced hypertension in male Wistar rats.. Hypertension was induced in uninephrectomized rats by weekly twice subcutaneous injection of DOCA (25 mg/kg bw) and 1% NaCl in the drinking water for six consecutive weeks. Effect of morin against DOCA-salt induced hypertension was evaluated by measuring blood pressure and performing biochemical estimations and histopathological examination of renal tissues.. DOCA-salt hypertensive rats showed considerably increased systolic and diastolic blood pressure, serum hepatic marker enzyme activities such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) and renal function markers (urea, uric acid and creatinine) in plasma. Oral administration of morin (25, 50 and 75 mg/kg bw) brought back all the above parameters to near normal level. Histopathology of kidney also confirmed the biochemical findings of this study. The effect at a dose of 50 mg/kg bw of morin was more pronounced than that of the other two doses (25 and 75 mg/kg bw).. These findings indicate that morin exhibits strong antihypertensive effect against DOCA-salt induced hypertension.

Morin attenuates blood pressure and oxidative stress in deoxycorticosterone acetate-salt hypertensive rats: a biochemical and histopathological evaluation.
    Metabolism: clinical and experimental, 2012, Volume: 61, Issue:8

    The present study was designed to evaluate the antihypertensive and antioxidant effect of morin, a flavonoid against deoxycorticosterone acetate (DOCA)-salt induced hypertension in male Wistar rats. Hypertension was induced in uninephrectomized rats (UNX) by weekly twice subcutaneous injection of DOCA (25mg/kg) and 1% NaCl in the drinking water for six consecutive weeks. The DOCA-salt hypertensive rats showed significant (P < .05) increase in the systolic and diastolic blood pressure, heart rate, water intake and organ weights (kidney, heart, aorta and liver). DOCA-salt hypertensive rats also showed significant (P < .05) increase in the levels of thiobarbituric acid reactive substances, lipid hydroperoxides and conjugated dienes in plasma and tissues (kidney, heart, aorta and liver), and significant (P < .05) decrease in the body weight, nitrite and nitrate levels in plasma and heart. Furthermore, the activities of enzymic antioxidants such as superoxide dismutase, catalase and glutathione peroxidase in erythrocyte and tissues and the levels of non-enzymic antioxidants such as reduced glutathione, vitamin C and vitamin E in plasma and tissues were significantly (P < .05) decreased in DOCA-salt rats. Morin supplementation (50mg/kg) daily for six weeks brought back all the above parameters to near normal level. The above findings were confirmed by the histopathological examination. No significant (P < .05) effect was observed in UNX-rats treated with morin (50mg/kg). These results suggest that morin acts as an antihypertensive and antioxidant agent against DOCA-salt induced hypertension.

The flavonoid morin restores blood pressure and lipid metabolism in DOCA-salt hypertensive rats.
    Redox report : communications in free radical research, 2012, Volume: 17, Issue:4

    This study was undertaken to investigate the antihypertensive and antihyperlipedimic potential of morin against deoxycorticosterone acetate (DOCA)-salt hypertensive rats.. Hypertension was induced in uninephrectomized rats (UNX) by weekly twice subcutaneous injection of DOCA (25 mg/kg) and 1% NaCl in the drinking water for six consecutive weeks. Morin (50 mg/kg) was administered to DOCA-salt rats orally using an intragastric tube daily for a period of 6 weeks.. The DOCA-salt hypertensive rats showed significant elevation in mean arterial pressure (MAP), heart rate (HR) and reduction in body weight. A significant increase in the concentrations of plasma and tissue (liver, kidney, heart, and aorta) lipids such as total cholesterol, triglycerides, free fatty acids, phospholipids, plasma low-density and very low-density lipoproteins cholesterol, and a decrease in the concentration of high-density lipoprotein cholesterol were noticed in DOCA-salt hypertensive rats. Also, the levels of urinary protein and the activity of 3-hydroxy 3-methylglutaryl coenzyme A reductase in the plasma and tissues were increased, and lecithin cholesterol acyl transferase activity in the plasma was decreased in DOCA-salt rats. Morin supplementation (50 mg/kg) throughout the experimental period restored all the above parameters significantly.. Morin has a potential role in attenuating severe hypertension and hyperlipedimia.

Effects of morin on blood pressure and metabolic changes in fructose-induced hypertensive rats.
    Biological & pharmaceutical bulletin, 2004, Volume: 27, Issue:11

    High fructose (HF) feeding induces a moderate increase in blood pressure in rats, which is associated with insulin resistance, hyperinsulinemia, and hypertriglyceridemia. In the present study, we examined the chronic effect of morin, a flavonoid isolated from medicinal plants, on blood pressure, lipid profiles, and serum insulin and glucose in HF-induced hypertensive rats. Rats were divided into control group and HF-fed group during the first three weeks of experiments. Then, rats were further divided into four groups and treated for 4 more weeks as follows: 1) control group; 2) morin-treated (intraperitoneal 5 mg/kg/d) control group; 3) HF-fed group; 4) morin-treated, HF-fed group (n=8, each group). Morin-treated HF-fed group showed lower systolic blood pressure (SBP) (132.0+/-2.5 mmHg vs. 142.8+/-2.2 mmHg, p<0.05), lower serum insulin level (1.21+/-0.27 vs. 2.73+/-0.30 microIU/dl, p<0.05), and lower plasma triglycerides (47.8+/-5.0 vs. 65.5+/-5.0 mg/dl, p<0.05) than those of HF-fed group. Morin treatment also suppressed mRNA expression of endothelin-1 (ET-1) in the thoracic aorta from HF-induced hypertensive rats. Moreover, decreased renal sodium excretion in HF-induced hypertensive rats was ameliorated by morin treatment. In conclusion, the results of this study demonstrate that morin has an anti-hypertensive effect in HF-induced hypertensive rats. This effect of morin may be associated with the suppression of serum insulin and plasma triglyceride level, with the down-regulation of ET-1 in the thoracic aorta, and with the partial amelioration of renal dysfunctions in HF-induced hypertensive rats.
