We have modified the EMIT (Syva) serum digoxin assay for use with a mini-disc centrifugal analyzer. A minicomputer is used to control data acquisition, calculations, and readout for 14 cuvettes simultaneously. Thus, it is not necessary for time each individual assay manually or to plot calibration curves on graph paper. We use incubation times and dilutions similar to those used for the manual ...

Chemical constituents and biological activities of the Mitrella kentii leaf oil were investigated in this study. Gas chromatography (GC) gas chromatography-mass spectrometry (GC-MS) used to determine chemical oil. The was evaluated for its ability inhibit prostaglandin E2 (PGE2) thromboxane B2 (TXB2) productions human whole blood using a radioimmunoassay technique. Its inhibitory effect on plat...

The availability of a radioimmunoassay for prostate-specific acid phosphatase has allowed a correlative study between this technique and conventional colorimetric assays in the four clinical stages of prostatic adenocarcinoma. Results of such a study show an increased diagnostic sensitivity of the radioimmunoassay in all stages, but in 14% of Stage IV adenocarcinomas there was no increase in pr...
