The HRP2 antigen can go through the cerebrospinal fluid (CSF). Purpose: To assess the HRP2-based RDT in malaria and detect the HRP2 in CSF. Methods: From November 2006 to May 2007, all patients under 15 years showing clinical symptoms of malaria were included. RDT was performed on the CSF and peripheral blood. Results: Out of the 951 patients included, 131 (13.7%) were confirmed through RDT and 130 (13.6%) through thick blood smear. Sensitivity and specificity stood at 96.96% and 99.71% respectively, for uncomplicated cases and at 100% and 99.13% for severe cases. Tests to detect HRP2 in the CSF of 52 cases were negative. Conclusion: Tests to detect HRP2 in the CSF could make it possible to diagnose severe malaria cases when peripheral parasitemia would be below the detection threshold.展开更多

Aromaticdiazonium ions, the ultimate carcinogen, were detected in the reaction with all of azo compounds as the substrates for HRP. The rates of oxidative cleavage fairly depended on pH. Relative enzymatic activities were compared among 15 non-aminoazo, dyes, and the structural requirements of the substrates for HRP were discussed in detail.展开更多
