Antiplasmodial and Antidiabetic Activities of Ethanolic Leaf Extract of Heinsia crinata
Okokon, Jude E.,Umoh, Emem E.,Etim, Emmanuel I.,Jackson, Clement L. The Korean Society of Food Science and Nutrition 2009 Journal of medicinal food Vol.12 No.1
The ethanolic leaf extract of Heinsia crinata, grown particularly for the leaf in Niger Delta region of Nigeria, was evaluated for antiplasmodial activity in Plasmodium berghei-infected mice as well as for hypoglycemic and antidiabetic activities in alloxan-induced diabetic rats. H. crinata (450-1,350 mg/kg/day) exhibited significant (P < .05) blood schizonticidal activity in both the 4-day early infection test and established infection with a considerable mean survival time, though not comparable to that of the standard drug, chloroquine (5 mg/kg/day). Treatment of alloxan-induced diabetic rats with the leaf extract caused a significant (P < .01) reduction in fasting blood glucose levels of normal and alloxan-induced diabetic rats both in an acute study and with prolonged treatment (2 weeks). The activity of the extract was comparable to that of the reference drug, glibenclamide, during the acute study but was not comparable to that of the standard drug during prolonged treatment. The results suggest that the leaf extract of H. crinata possesses significant (P < .05) antiplasmodial as well as hypoglycemic and antidiabetic effects that can be employed in health care.

This study was carried out to investigate the effect of oral dietary supplementation with ginger on cadmium-induced toxic effects on biochemical, hematological, and pathophysiological indices of albino rats. The effect of cadmium and cadmium/ginger treatment on lipid peroxidation was measured by malondialdehyde (MDA) levels in testes and kidney; serum activities of alkaline phosphatase (ALP), acid phosphatase (ACP), and prostatic acid phosphatase (PAP) enzyme were investigated alongside hematological indices. The results showed that cadmium induces a significant increase in both testicular and kidney MDA, whereas cadmium/ginger treatment produced a significant reversal of the effect of lipid peroxidation (P=.004). Cadmium treatment induced 75%, 78%, and 22% increases in activities of ACP, PAP, and ALP, respectively, whereas the cadmium/ginger-treated group reversed these values for enzyme activities (P=.001). Results of organ weight and hematological indices analysis in the cadmium-treated rats showed a decrease in organ weight and distortion of the hemopoietic features, whereas the cadmium/ginger-treated rats showed an improvement in organ weight and hematological indices (P=.04 and .001, respectively). The reversal of the toxic effects of cadmium in the cadmium/ginger-treated albino rats heralds the antioxidant potency of ginger toward cadmium toxicity-associated oxidative stress.
