4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

Real and simulated particulate fallout solutions of 134CsCl were fed to 102 healthy volunteers. An average of 3% of the radioactivity of week-old fallout was absorbed: the range was 0-9%.

Data were obtained for the distribution-excretion pattern of 137Cs in guinea pigs over a period of 100 days after administration by three different routes. Three groups of twenty guinea pigs were used. Solutions of cesium chloride containing 137Cs as a tracer were administered to the animals by inhalation, by ingestion and by i.p. injection. Urine and feces were collected daily until sacrifice, and the time-tissue distribution patterns were determined after death. All measurements were made by gamma counting with a NaI (Tl) detector. Since cesium chloride is extremely soluble, it was absorbed rapidly from the lungs, the digestive tract and the abdominal cavity. After the first day, the skeletal muscle had the largest concentration of 137Cs. Its retention in muscle may be approximated by a single exponential function with an average biological half-life of 10 days. Concentration in other tissues did not differ significantly from that in the muscle. The 137Cs concentration in total excretion followed an exponential pattern with a rapidly and a slowly decreasing component. The average urine-to-feces ratio was 2.8. More than 95 per cent was excreted within 32 days; at this time, approximately 65 per cent of the remaining radioactivity was located in the skeletal muscle.

Absorption of CsCl, SrCl2, BaCl2 and CeCl3 deposited on nasal membranes directly into the general circulation was studied in Syrian hamsters and compared with gastrointestinal tract absorption. More than 50 % of the cesium, strontium and barium was absorbed directly from the nasal membranes but <4 % of the cerium. For all isotopes, nasal absorption was approximately = or >gastrointestinal absorption during the first 4 hr after administration. This study emphasized the importance of direct nasal absorption of deposited materials in inhalation toxicity evaluations especially with readily soluble aerosols having mass median aerodynamic diameters >5 m when nasopharyngeal deposition predominates.

4.2 Mechanism of Action

... potassium channel blocker ... capable of producing early after-depolarizations (EADs) and polymorphic ventricular tachyarrhythmias resembling torsades de pointes.

Cesium ions block potassium channels in biological membranes in a voltage dependent manner. For example, external cesium blocks inward current with little or no effect on outward current. Consequently, it produces a characteristic N-shaped current-voltage relationship. /Cesium ions/
