RESUMO
This paper presents the implementing multiple fan beam projection technique using optical fibre sensors for a tomography system. From the dynamic experiment of solid/gas flow using plastic beads in a gravity flow rig, the designed optical fibre sensors are reliable in measuring the mass flow rate below 40% of flow. Another important matter that has been discussed is the image processing rate or IPR. Generally, the applied image reconstruction algorithms, the construction of the sensor and also the designed software are considered to be reliable and suitable to perform real-time image reconstruction and mass flow rate measurements.

Archaeological, anatomical, linguistic, and genetic data have suggested that there is an old and significant boundary between the populations of north and south China. We use three human genetic marker systems and one human-carried virus to examine the north/south distinction. We find no support for a major north/south division in these markers; rather, the marker patterns suggest simple isolation by distance.

The purpose of the study is to explore the relation between general condition of patients with recurrent aphthous ulcer (RAU) and human zinc and copper with TCM conception of the organism as a whole, and adjustment effect of human body zinc and copper by TCM treatment. Results showed that the average value of serum zinc of 75 cases of RAU was on lower level within normal range, serum copper was normal, the rate of copper to zinc was higher than normal value. Analysis using the TCM theory showed serum zinc of patients of deficiency symptom-complex was lower than excessiveness symptom-complex, the rate of copper to zinc of patients of deficiency symptom-complex was higher than normal range. The zinc content of serum and the rate of copper to zinc were different in patients of various symptom-complexes of RAU. The zinc and copper contents of serum were adjusted, the rate of copper to zinc was normalized and the immune function of T-cell increased distinctly by TCM treatment according to an overall differentiation of symptoms and signs. Thus the therapeutic effect of TCM was better than zinc preparation.

For early diagnosis of malignant changes, in oral leukoplakia and lichen planus based upon the experience of experimental study we did before, several non-traumatic examination methods were used in clinical cases. Results showed that the accurate rates of toluidine blue staining and hematoporphyrin derivative (HpD) local application are 90 percent. Transmission electron microscopic study of cytology indicates that cellular ultrastructures are different distinctly between cells of the malignant tissue and normal mucous membrane or leukoplakia with simple hyperplasia.
