and evaluation of the wound healing properties and safety assessment of two seaweeds ( and ).

Seaweeds have been regarded as a reservoir of biologically active molecules that are important in the pharmaceutical industry. The aim of the present study was to explore the wound healing properties and to assess the safety of the seaweed and Enhanced cell proliferation and cell migration activities were observed in L929 cells treated with extract compared to extract treated cells and the control group. In-vivo experiments were conducted using five groups (10 in each) of Albino mice (BALB/c). Mice in group I and group II were treated (Orally, 100 mg/kg BW/day) with aqueous extracts of and , respectively for 14 days. Treatment group III received a topical application of the aqueous extract of (25% w/w) and ointment base (75% w/w) (2 g/kg BW/day, for 14 days). Group IV (Control) received an equal amount of distilled water, orally and mice in group V kept without wounds. The extract from showed stronger wound healing properties than the one from . Histopathological findings also revealed that the healing process was significantly enhanced in the mice group treated orally with aqueous extract. These findings show that species possess promising wound healing properties and .
