Effect of cesium and potassium salts on survival of rats bearing Novikoff hepatoma.
The effect of CsCl on the life span of female Sprague-Dawley rats innoculated with Novikoff's hepatoma was studied as a function of both pre- and post-treatment with CsCl and as a function of the inoculant dose. The effect of KCl on the CsCl treatment was also studied. Rats treated with CsCl for 12 consecutive days prior to or immediately after inoculation with 1.0 ml of viable hepatoma cell suspension showed an increase in mortality score from corresponding controls. Conversely, increases in the dose of the inoculant resulted in delaying the onset of toxicity in rats receiving the Cs-treatment after inoculation as evidenced by a decrease in mortality. Availability of KCl in drinking water ad lib further decreased total mortality when given alone but not when combined with CsCl. The results indicate a dose-dependent paradoxical effect of CsCl on Novikoff hepatoma cell toxicity and suggest a critical intercellular balance requirement between Cs+ and K+ on the effect studied.
