RESUMO

Objective:To determine the curative effect of Ginkgo Biloba extract on the back chapped skin in SD rats. Methods:Totally 60 SD rats were randomly divided into 6 groups with 10 rats in each. One group was the blank control group, while the other five groups with the same back chapped skin were respectively treated with different therapy regimen, namely one group was the model group without any treatment, one group was urea group treated with the commercially available urea, and the last three groups were re-spectively treated with Ginkgo Biloba extract at the dose of 5%, 1% and 0. 2%. The pathological tissue was observed after HE stai-ning, and the content of hydroxyproline ( Hyp) in skin was determined by alkaline hydrolysis. Results:The skin lesion and the score of pathological section were studied and the content of Hyp in the damaged skin was determined. The comprehensive score for the groups was 0, 13. 2, 7. 4, 11. 0, 5. 8 and 6. 6, respectively, and the content of Hyp was (4. 57 ± 0. 07), (2. 41 ± 0. 27), (3. 29 ± 0.57), (2.55 ±0.31), (3.24 ±0.26) and (3.37 ±0.24) μg·mg-1,respectively. There was significant difference in the curative effect between the Ginkgo Biloba extract groups at high dose (5%) and medium dose (1%) and the model group (P0. 05). Conclusion:The extract of Ginkgo Biloba has a certain effect on the back chapped skin in SD rats, which may contribute to the external preparations of Ginkgo Biloba extract.
