| Abstract:
|
Ethanolic extracts of A. sativum and T. belerica, recommended in Ayurvedic system of
medicine for use in asthma, were evaluated for mast cell stabilizing and anti-cataleptic activity to
find possible mode of action of these plants in management of asthma. Clonidine-induced mast
cell degranulation was used to assess mast cell stabilizing activity of the extracts, while effect of
extracts on catalepsy was evaluated by clonidine and haloperidol-induced catalepsy. In clonidineinduced
mast cell degranulation, mice pretreated with disodium cromoglycate, A. sativum or T.
belerica showed significant reduction in degranulation as compared to control group. Single dose
of A. sativum potentiated clonidine-induced catalepsy but on repeated doses (once in a day for 4
days) inhibited catalepsy, while T. belerica inhibited catalepsy even on single dose treatment.
Both plants showed no effect on haloperidol-induced catalepsy. The results of present study
suggest usefulness of A. sativum and T. belerica in management of asthma probably due to their
mast cell stabilizing effect.
