Effect of Vitamin E on Platelets Changes Associated with Decompression

The influence of vitamin E on platelets changes of rats associated with decompression was studied. In the first study, rats stayed at 6 ATA for 2 hours and were decompressed in 15 minutes, and platelet count fell from 56.13•}4.14•~104/mm3 to 39.06•}12.98x104/mm3 after decompression. In the second study, rats were devided into 3 groups: group A rats were fed vitamin E-deficient diets (tocopherol 3 mg/kg), group B rats were fed control diets (tocopherol 18 mg/kg), and group C rats were fed vitamin E diets (tocopherol 180 mg/kg). These groups were fed for 3 months. Platelet count fell from 64.84•}3.70•~104/mm3 to 56.66•}5.03•~104 mm3 after decompression in group A. Platelet count fell from 56.28•}3.12•~104/mm3 to 45.62 •} 13.84•~104/mm3 in group B. But there was no significant changes of platelet in group C. In the third study, survival rate after decompression was studied. Highest survival rate was group C (50.0%) and lowest survival rate was group A (16.7%). These results sug-
