[Determination of bufothionine in skin of Bufo bufo gargarizans and Huachansu injection].

OBJECTIVE: To establish a HPLC method for bufothionine in the skin of Bufo bufo gargarizans and Huachansu injection. METHOD: The samples were separated using a Lichrosob C18 column with CH3CN-H2O (10:90) as mobile phase. Flow rate was at 1.0 mL x min (-1) and the detection wavelength was at 225 nm. RESULT: The calibration curve of bufothionine was linear over the range of 0.0772-0.4632 microg and the average recovery was 99. 2%. The contents of bufothionine were fluctuated from 36.4-641.8 microg x g(-1) in the skin of Bufo bufo gargarizans and 22.47-33.16 microg x mL(-1) in Huachansu injection, respectively. CONCLUSION: The contents of bufothionine were greatly different between cultured and wild species. The method was suitable for the quality control of the skin of Bufo bufo gargarizans and its preparation.

Reye's syndrome.

Although most cases of Reye's syndrome that were initially reported were fatal, the overall mortality is now 20 to 30 per cent, with an even lower rate in some series. Improvement is due to both increased awareness of this disease and advances in care for the critically ill child. A good outcome depends on recognition of the early manifestations of the syndrome and appropriate initial therapy based on the stage of the disease.
