ABSTRACT
OBJECTIVE:To establish a HPLC method for the determination of gentamycin sulfate C component in medicinal albumin gel. METHODS: Samples was separated on Agilent ZORBAX Eclipse XDB-C8 at a column temperature of 26℃. The mobile phase was methanol-acetic acid-water (70∶5∶25, added with 0.02mol?L-1 sodium heptanesulfonate solution) for gradient elution at a flow rate of 1.0mL?min-1. The detection wavelength was set at 330nm. RESULTS: Baseline separation of gentamycin sulfate C component in medicinal albumin gel was achieved. The linear range of gentamycin sulfate C component was 0.26?g～6.50?g and its average recovery rate was 90.0%, RSD=0.43%, the lowest limit of detection was 0.368ng. CONCLUSION: The method was proved to be simple, accurate and reliable, and suitable for the content determination of gentamycin sulfate C component in related preparations.
ABSTRACT
OBJECTIVE:To explore the method and efficacy of occlusion with medicinal albumin gel for esophageal fistula. METHODS:Over the recent 5 years,a total of 11 patients with esophagus -respiratory fistula or esophagus-neck fistula confirmed by iodine imaging and / or gastroscopy were occluded with medicinal albumin gel under endoscope. RESULTS:The occlusion with medicinal albumin gel for esophageal fistula was successful in all the 11 cases,and 9 out of 11 were completely healed after one time occlusion treatment and the other 2 cases were completely healed after the second occlusion treatment. The average hospital stay was 27 days and the average cost was 24,500 yuan. There was no recurrence after follow-up of 3 to 6 months,nor was there any adverse complication. CONCLUSION:Compared to the conventional conservative treatment,occlusion with medicinal albumin gel for esophageal fistula under endoscope can reduce the length of hospital stay and the cost of hospitalization.
