[Methods]Eucalyptus oil samples with different dilution ratio were detected by TLC. Eucalyptus oil was intragastrically administered to mice,serum samples of different eucalyptus oil doses,different intragastric administration methods and different blood sampling times were collected. The above samples were detected by TLC,and the above results were verified by gas chromatography. [Results] TLC can detect concentration difference of eucalyptus oil samples with different dilution ratio. TLC can provide qualitative and semi-quantitative detection of eucalyptus oil in serum. High,medium and low dose of eucalyptus oil in serum had different effects on the growth of MCF-7 cells in the SD rats( P < 0. 05). [Conclusions] TLC can be used to guide the preparation of drug containing serum of eucalyptus oil.展开更多

Methods: The paired urine and serum specimens from 273 drug users detained at a detoxification unit were collected, and the HIV-1 antibodies in the specimens of them were screened by urine and serum ELISA kits, respectively. Results: Of 273 serum specimens, 94 ones showed positive reaction and among 94 counterpart urine specimens, 93 ones also appeared positive reaction. Taking the results together,the consistent rate of HIV-1 antibody screened by urine and serum ELISA kits was 99.6%. Conclusion: The urine ELISA kit, which screened HIV-1 antibody of urine showing almost the same results tested by serum ELISA kit, is reliable. It is proposed that urine ELISA be introduced in many fields.展开更多
