Alpha-2-HS-glycoprotein polymorphism in New Zealand Europeans and New Zealand Maori.

The polymorphism of alpha-2-HS-glycoprotein (AHSG, alpha 2HS) was analysed in a sample of New Zealanders consisting of 194 New Zealand Europeans and 236 New Zealand Maori. Thin layer polyacrylamide gel isoelectric focusing followed by immunofixation revealed four different AHSG phenotypes in New Zealand Europeans and three different AHSG phenotypes in New Zealand Maori. The AHSG*2 frequency of 0.

ABO, phosphoglucomutase and erythrocyte acid phosphatase typing of blood samples containing added fluoride.

Blood samples containing approximately 2% and 4% sodium fluoride have been stored at 4 degrees C for up to 5 months and 4 weeks respectively. ABO typing by absorption-elution was successful on stains made from almost all of the samples. PGM subtyping by isoelectric focusing was successful on most samples, with clearer results from whole blood than from stains.

Urinary Metabolites of Anabolic Steroids.

Anabolic steroids are abused for performance enhancement by athletes, and for appearance alteration by others. Urine drug testing is an effective deterrent in reducing their abuse. We have reviewed the current status of published information on the urinary metabolites (neutral fraction) of 17 anabolic steroids.

Development of a method for the determination of zopiclone in whole blood.

Mass spectrometry in both electron-impact and positive chemical ionisation modes has been used to elucidate the structures of the decomposition products of zopiclone after gas chromatography. A high-performance liquid chromatographic method has been developed for the determination of zopiclone in whole blood. After selective extraction (butyl chloride) the extracts are chromatographed on Spherisorb ODS-5 (5 microns) using dibasic ammonium phosphate-acetonitrile (40:60).
