Anti-inflammatory and anti-platelet aggregation activity of human placental extract.
Acta Pharmacologica Sinica 2003 Februrary
AIM: To find the anti-inflammatory and anti-platelet aggregatory activity of human placental extract (HPE, Placentrex).
METHODS: The HPE was studied for anti-inflammatory effect in Wistar rats on carrageenin, serotonin (5-HT), and prostaglandin E1 (PGE1) induced edema in acute model and cotton pellet induced granuloma on sub-acute model. Anti-platelet aggregation was studied against protection of adinosine diphosphate (ADP)-induced aggregation of human platelet through in vitro study.
RESULTS: HPE showed positive results both in acute and sub-acute models of inflammation. Highly significant (P<0.01) results were obtained against 5-HT induced acute inflammation and cotton pellet induced sub-acute inflammation in comparison with standard (diclofenac sodium) and control (normal saline) drugs. The anti-inflammatory property of HPE in animal model was well supported with clinical study of platelet aggregation. There was highly significant (P<0.01) inhibition of platelet aggregation with HPE at different doses against ADP.
CONCLUSION: Our data suggest that human placental extract may be useful in suppressing inflammation and platelet aggregation.
