0 ^05). Giemsa positive samples were all positive by PCR-ELISA. The negative control group had one positive by ELISA in lung tissue and BALF respectively. Conclusion PCR-ELISA shows a high sensitivity and specificity in detecting the DNA of Pneumocystis carinii, which is a secure and easy use method.

Objective To make staining preparation of tapeworm for the purpose of teaching and scientific research.Methoeds Pregnant segmens were stained by Indian ink,and mature segments,cephalomeres and bladder worms were stained by carmine.Result After staining the characteristics of pregnant segments,mature segments,cephalomeres and bladder worms were observed obviously.For instance,the stem and branches linking both-side of uteri in pregnant segment and reproduction cavity projecting in one of edges in the center of the pregnant segment were clearly shown in ink colour after stained by Indian ink.The red colour was shown in the mature segment with deep-coloured male and female reproduction systems inside,separately,after stained by carmine.Conclusion Tapeworm preparation stained by Indian ink and carmine is useful and can be preserved permanently.
