In the face of the human body,it has a broad role in many ways. O. basilicum has a long history of folk application and research,and very high officinal,edible and economic value. Combining with modern analysis and detection technology,the effective parts of O. basilicum are studied and utilized. The discovery of new drugs will have important practical significance for the development and application of O. basilicum.展开更多

The changes of optical properties of biological tissue are due to the refractive indices matching between the scatterers with high refractive index and the ground substances, which reduce scattering of tissue. The main reasons are that permeated semipermeable chemical agents with higher refractive index than the ground substances of tissue makes the refractive index of ground substances of tissue higher by the enhancement of the permeated concentration. We studied on the collimated transmittance changes of light penetrating biological tissue after the hyperosmotic chemical agents administrates with different concentration.展开更多
