Objective:
To investigate the cough-relieving, analgesic and antibiotic effects of durian shell extract (DSE) in relieving cough and its analgesic and antibiotic effects.
Methods:
The effect of DSE in relieving cough was assessed in mice challenged with ammonia and SO(2) to induce coughing. The analgesic and antibiotic effects of DSE in mice were evaluated by hot plate test and twisting reaction induced by acetic acid, and by minimal inhibitory concentration (MIC) and disc-agar diffusion tests, respectively.
Results:
Compared with the control group, the mice treated with 300 and 900 mg/kg DSE showed significantly prolonged latency with decreased number of coughing induced by ammonia and SO(2), and the effect was dose-dependent. DSE markedly prolonged the latency and decreased the twisting number of the mice induced by acetic acid without affecting the pain threshold in hot plate test. DSE produced no significant inhibitory effects against Staphylococcus aureus, Staphylococcus epidermidis, or E. coli, and showed a week inhibition against Bacillus aeruginosus.
Conclusion:
DSE shows obvious effect in relieving cough and produces better analgesic effect against chemical factor-induced pain than against physical agent-induced pain sensation. DSE has a moderate inhibitory effect against Bacillus aeruginosus.
