Abstract
Purpose:
The aim of this
study was to investigate the anti-inflammatory and
wound-healing activities of the protease isolated from
the latex of Plumeria rubra Linn.
Methods:
The protease was isolated from the latex of the plant by
acetone precipitation method and given a trivial name,
Plumerin-R. The anti-inflammatory activity of the
protease was based on its effects on carrageenan-induced
paw oedema in rats. Its wound healing effect was
investigated using an excision wound rat model.
Results:
Four hours after
treatment, the reduction in carrageenan-induced rat paw
oedema by 20, 40 and 80 mg/kg body weight of plumerin-R
was 21.6, 33.8 and 48.8 %, respectively, while oedema
reduction by indomethacin (10 mg/kg) was 58.0 %.
Plumerin-R showed significant (p < 0.05) wound closure
and epithelialization time compared with control.
Conclusion:
This study
demonstrates that the protease, Plumerin-R, has
significant anti-inflammatory and wound-healing
properties.
