Pharmacodynamic Evaluation of Tanreqing Inhalation Solution
antipyretic and anti-inflammatory effects of Tanreqing inhalation solution
and provide basis and data support for further research and development of this preparation.
Method:
2
The methods of cough induced by ammonia and tracheal phenol red excretion were used to observe the antitussive and expectorant effects of Tanreqing inhalation solution in mice. The fever model of rats was established by intraperitoneal injection of bacterial lipopolysaccharide(LPS) to observe the antipyretic effect of the Tanreqing inhalation solution
the acute pneumonia model of rats was established by atomizing LPS inhalation
and the anti-inflammatory effect of Tanreqing inhalation solution was observed.
Result:
2
Tanreqing inhalation solution could reduce the number of coughs in mice induced by ammonia water
increase the amount of phenol red excretion in mouse trachea
decrease the levels of body temperature and its related regulatory factors of prostaglandin E
2
(PGE
2
) and cyclic adenosine monophosphate(cAMP) of rats induced by LPS
decrease the white blood cell(WBC) count and the neutrophil ratio(NEUT) in bronchoalveolar lavage fluid(BALF) of rats with LPS-induced acute pneumonia
and reduce the levels of nuclear transcription factor-
κ
B(NF-
κ
B) and interleukin-1
β
(IL-1
β
) in lung tissue.
Conclusion:
2
Tanreqing inhalation solution has obvious antitussive
expectorant
antipyretic and anti-inflammatory effects
which is worthy of further development and promotion.
