A comparative study of HPLC and TLC separation of amino acids using Cu(II) ion.

Separation of amino acids using Cu(II) by RP-HPLC and impregnated TLC is reported. For HPLC the sample mixture of amino acids containing copper (II) was injected into the column while for TLC the silica gel plates were impregnated with Cu(II). The mobile phase used in HPLC was acetate buffer (0.3 M, pH 6.0)-acetonitrile (9:1, v/v), and that in TLC was acetate buffer (0.3 M, pH 6.0):acetonitrile-n-butanol (12:5:10, by vol.). The results have been compared and discussed.

TLC separation of certain tetracycline and amino glycopeptide antibiotics.

The separation of tetracycline and amino glycopeptide antibiotics was achieved on silica gel thin layers. Tetracycline antibiotics were resolved on a Co+2 (1.0%) impregnated silica gel layer using ethanol:acetic acid:water (10:6:6, v/v/v) as the mobile phase. Amino glycopeptide antibiotics were separated on an untreated silica gel layer using the mobile phase n-butanol:formic acid:water (6:5:7, v/v/v). The spots of these antibiotics were located by exposing the chromatoplate to iodine vapours.

Cytologic findings in female and male offspring of DES treated mothers.

Data on vaginal, cervical, and endocervical samples and urine specimens of 84 female offspring exposed to diethylstilbestrol in utero and 43 controls have been presented. The colposcopic and histopathologic findings were correlated with the cytologic findings. Our preliminary findings indicate that the cytologic technique is reliable as screening test for vaginal epithelial changes in the DES-exposed females provided the sampling procedure is adequate. In 79 male patients, 42 DES-exposed and 37 controls, the pre-massage urine, the prostatic fluid, the post-massage urine and aspirate of cysts of the epididymis when existing were examined by cytologic techniques. No tumor cells were found in the cytologic specimens of the exposed and unexposed male and female offspring.
