Assessment of Antioxidant and Antineoplastic Activities Blumea Lacera (Burn. F) Leaves
Blumea lacera (Burn. f.) DC. (Family: Asteraceae) is an important member of Bangladeshi natural plant resource and it is an herbaceous weed locally known as Kukursunga. Different parts of this plant are used traditionally to cure various diseases. But detail study on the antioxidant and antineoplastic potentials of Blumea lacera leaves, has not yet been done. Aim of this study is to examine the antioxidant and antineoplastic properties and quantify the different type of phytochemical content of the methanolic extract of leaves of Blumea lacera (MELB). MELB contained a rich polyphenol, flavonol, flavonoid and proanthocyanidins. MELB showed moderate cytotoxic effect against Artemia salina (brine shrimp nauplii) where its LD50 values was 66.12 μg/ml. In vitro antioxidant assay, MELB exhibited a remarkable capacity to scavenge the tested reactive species. MELB scavenged DPPH with an IC50 of 33.64 μg/mL and 42.69 μg/mL, respectively. In vivo antineoplastic assay, MELB significantly (P<0.05) decreased viable cell count and increased the survival time of EAC cell bearing mice. Hematological profiles were also restored significantly (P<0.05) to normal levels in MELB treated mice as compared to untreated EAC control mice. In addition, fluorescence microscopic view of EAC cells derived from MELB-treated group showed apoptotic characteristics in treated cells compared to untreated EAC control. our findings suggest that methanolic extract of Blumea lacera leaves(MELB) might be a potential agent with antioxidant properties for prevention of cancer and has the merit for further investigation in isolating its active constituents.
Effects of Transfer Point Glucan #300 Supplementation on Children exposed to Passive Smoking - Placebo-driven Double-blind Clinical Trials
In this study, we focused on the effect of β-glucan supplementation of children with chronic respiratory problems. We measured the levels of cortisol, salivary IgE and cotinine in 56 children and evaluated the effect of 30 day supplementation with 100 mg/day oral dose of yeast-derived β-glucan. Our results showed strong decrease of cotinine and cortisol levels in saliva of β-glucan-supplemented children.
