[Normative research on bacteriostasis and relieving itching external therapeutic function of kochiae fructus]

To normalize bacteriostasis and relieving itching external therapeutic function of Kochiae Fructus.

Itching guinea pig model caused by histamine, itching mice model, eczema guinea pig model caused by OVA, and inhibitory effect on pathogens in vitro were used to observe the itching threshold, symptoms and other related physiological index, as well as the inhibitory effect on the normal skin fungi by water extraction of Kochiae Fructus to evaluate the external therapeutic function of Kochiae Fructus.

The itching threshold of guinea pig itching model treated by water extraction of Kochiae Fructus at high, medium and low three dosage level, could be significantly increased when compared with negative control group (P < 0.05 or P < 0.01); Red speckle of OVA guinea pig model treated by water extraction of Kochiae Fructus at high, medium and low three dosage level, could be significantly decreased when compared with negative control group (P < 0.05 or P < 0.01); The number of itching and total time of itching within 30 minutes of mice model caused by R-glycose anhydride treated by water extraction of Kochiae Fructus at high, medium and low three dosage level, could be significantly decreased when compared with negative control group (P < 0.05 or P < 0.01); Several common skin fungi could be significantly inhibited by the water extraction of Kochiae Fructus. MIC of the water extraction of Kochiae Fructus on Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum canis, Trichophyton violaceum, and Trichophyton schoenleini were 3.12%, 0.78%, 0.78%, 0.78%, 0.78%, respectively.

Kochiae fructus has the effect of bacteriostasis and relieving itching.
