On the observation and the measurement of microcirculation, there are many me-thods. Recently, it is often used that the cast is taken by means of injection of acrylic resin and is observed by scanning electron microscope. However, there was only a little report con-cerning the validity of the measurment of microvessels. Therefore, in this study, jejunum of a rat was used. This study was attemped to examine the difference between the cast and the other methods (capillary microscope, electron Inicroscope, Indian ink injection and microangiogram).
In addition to the microvascular system of the rat’s jejunum was obscrved on the cast.
Results were as follows:
1.Colnpared with the other methods except microangiogram, it almost regards the diameters of vessels which were measured on the cast in the approximate value with them. The cast can be very useful method at the measurment.
2.The vascular system of the rat’s jejunum is useful for the purpose of absorption, secretion and control of the amount of the following blood easily.
