Liquid chromatographic analysis of dihydrostreptomycin sulfate.

The analysis of dihydrostreptomycin sulfate using a column packed with base deactivated reversed phase silica gel and ultraviolet detection at 205 nm is described. The mobile phase consists of an aqueous solution containing 4 g/l of sodium sulfate, 1.5 g/l of sodium octanesulfonate, 100 ml/l of acetonitrile and 50 ml/l of a 0.2-M phosphate buffer at pH 3.0. The method allows separation of streptidine, dihydrostreptomycin B, streptomycin, dihydrostreptomycin and deoxydihydrostreptomycin, as well as some other components which were not identified. The total time of analysis is 55 min. The effects of the different chromatographic parameters on the separation were also investigated. A number of commercial samples were analyzed using this method.

[The pharmacokinetics of dihydrostreptomycin sulfate in domestic pigeons (Columba livia Gmel., 1789 var. domestica)].

A 20% aqueous solution of dihydrostreptomycin sulfate in a dosage of 100 mg/kg b.w. is non-toxic for pigeons, although renal accumulation occurs. 12 hours after a single subcutaneous injection of 100 mg/kg b.w. the plasma concentration decreases to 3.64 micrograms/ml and therefore below the therapeutically effective concentration, while in birds suffering from salmonella infections plasma levels decrease to comparative concentrations (3.84 micrograms/ml) after only 8 hours. Contrary to the directions for use in pigeons of the preparation CX 60, the subsequent dosage should be given no later than 10 hours after the first application.

Cell proliferation in spiral ligament of mouse cochlea damaged by dihydrostreptomycin sulfate.

Cell proliferation of the spiral ligament in the normal and drug-induced damaged mice cochleae was investigated using the mitotic tracer bromodcoxyuridine (BrdU). Only a few nuclei labelled by BrdU were seen in the spiral ligament of the control mouse. However, many BrdU labelled nuclei in the spiral ligament in the cochlea damaged by dihydrostreptomycin sulfate were found. The expression of fibroblast growth factor receptor and connexin 43 was detected in the spiral ligament where BrdU labelled cells were found. These results suggest that cell proliferation in the spiral ligament may occur after the drug-induced damage, and this process is probably related to the recovery of cochlear function.
