    Summary Several extraction, separation and detection methods for heterocyclic amines (HAs) in chicken legs were evaluated by liquid chromatography. Results showed that the most appropriate extraction method includes the removal of macrosubstances by centrifugation and subsequent purification using a PRS (propylsulfonic acid silica gel) and a C18 cartridge, and the recovery obtained ranged between 51 and 89 %. For HPLC separation, a binary solvent system consisting of acetonitrile and 0.05 M ammonium acetate solution (pH 3.6) with gradient elution with flow rate of 1.0 mL min−1 and detection at 258 nm was used to resolve 16 HAs. With fluorescence nine HAs could be detected by employing a programmable wavelength, and the sensitivity was 100–400 times higher than that by UV detection. The detection limits for UV and fluorescence detection were 0.02≈0.5 ng and 0.05≈3 pg respectively, with a signal-to-noise ratio 3. The presence of HAs in fried chicken legs was also determined.

    Notes:
    In vivo and electron microscopy were used to study the hepatocellular responses of rat livers to intravenously injected polymeric microspheres. Two microsphere preparation with different surface characteristics and degradability were used in this study. In vivo microscopy revealed that both poly(benzyl L-glutamate) (PBLG) and poly(hydroxypropyl L-glutamine) (PHPG) microspheres caused disturbance in the microcirculation of rat liver up to 2 months after injection. The observed changes included stagnant flow and adherence of white blood cells to the endothelial lining of venules and sinusoids. Kupffer cell (KC) activation following phagocytosis of microspheres was evidenced by the enlargement of KCs and increased number of KCs taking up fluorescent latex particles. Electron microscopy of rat livers revealed a wide range of hepatocellular injury associated with the administration of PBLG and PHPG microspheres. These results indicate that a small amount of remaining microspheres is sufficient to induce continuous disturbance to hepatic microcirculation and that particulate drug carriers should be designed to be rapidly degraded so that the return to normal liver function is possible. © 1994 John Wiley & Sons, Inc.
