The Hepatic B Surface Antigen under Electron Microscope / 昆明医科大学学报

It has been repored that the Biopsy positive rate of HBsAg in the liver specimens of the patients of hepatitis B was only 70% or so.We have observed with electron miroscopy the liv- er biopsy tissues and found that its positive rate was as high as 93.8%.Under electron microscopy,we could identify the HBsAg filaments as tubular,branching-tubular and tubu- lar-vesicular.We have also found that it was not easy to find the HBsAg filaments in the pa- tients of CAH(only 9% was found)and it was easy to be found(78.9%)in the patients of CPH or CLH. It had a high significant difference in the two groups.
