Abstract: | Solution based on disodium glycerophosphate have been assessed for ability to inhibit cellular swelling during hypothermic storage of slices of rabbit renal cortex. It was found that slices stored in glycerophosphate media for 3 days gained about 50% of their control weight, whereas control slices stored in chloride based media gained 50% of their control weight after only 2 hr of storage and gained about 128% of their initial weight after 3 days. Electrolyte content of slices stored at 4 °C reflected the change in hydration. When slices were warmed after various storage times, it was found that viability was much better preserved in glycerophosphate saline than in chloride based saline, although the slices stored in glycerophosphate media contained more sodium prior to warming than slices stored in conventional media. Glycerophosphate solutions appear to be suitable for routine use in experiments with renal cortical slices in the vicinity of 0 °C when cell volumes are to be held constant for prolonged periods. |
