Résumé

To clear the effect of the wound to the growth of the larva of the host to the Ophiocordyceps sinensis, the wounds of same severity at the same position were made artificially to the larva and which were artificial fed at the same environment and condition. The results indicated that, over the winter, the survival rate of the wounded of the infection larva was lower than that of the healthy larva, but the weight had no significant difference between the wounded and the healthy larva. The survival rate of the wounded of the no infection larva was lower than that of the healthy larva, but except with black skin, the wounded larva with offwhite and dusty red had no influence on the variety of the weight. In summery, wound had no advantage to the survival rate, but had no influence to the weight. The result had provided theoretical basis to the reforming of the system of the artificial culture O. sinensis.

Résumé

A high resolution Micro-CT system for small animal imaging is introduced in this paper. Micro-focus X-ray tube with focal diameter of 100 microm and flat panel detector with imaging area of 13cm x 13cm are adopted in this system. The data acquired in rotation scanning is reconstructed with cone beam algorithm. The resolving power of the detector is measured to be 31 lp/cm at 10% of the MTF. The resolution of the Micro-CT system could achieve 185 m when the magnification factor is 1.94. Thighbone of a rabbit is used as sample imaging with the system. The trabecular bone could be imaged clearly. And the ability of small animal imaging of the system has been demonstrated.

Résumé

In this review, we introduce the basic principle and technology progress of tissue optical imaging from both diffuse optical imaging and coherence domain imaging, which include the continuous-wave imaging, time-resolved optical tomography, diffuse photon density waves tomography, ultrasound-modulated optical tomography, optical coherence tomography and laser speckle imaging. Applications of optical imaging in brain activity and tissue function are also discussed.
