RESUMEN
To improve the accuracy of finite element method used in medicine field, it is necessary to build the finite element model including real structural information of tissues in human body. In this study, an edge extracting method was introduced on CT image of human body, and the method of building the two-dimensional finite element model from the extracted edges was then raised. Using the above methods, a finite element model of human body containing real structural information can be successfully made. The methods were used for many CT images of hospitals and tested to be simple, fast and adaptable. The study makes a good foundation for further finite element analysis based on medicine images.
RESUMEN
The von willebrand factor (vWF) and angiotensin converting enzyme(ACE) were measured in asthmatic patients in stages of attack and remission, using ELISA and ultraviolet methods. The results showed that the vWF and ACE were (72.1 ? 58.3)%, and 22.9 ? 6.9U in the stage of attack, and (68.8 ? 42.1)% and 23.2? 7.9U in the stage of remission, respectively. All these values were significantly lower than that of healthy controls [(117.1 ? 50.30)% and 31.3 ? 9.3U, respectively, P
