Some effects of PCO2 and pH on nerve tissue.

1. Rat phrenic nerve preparations were used in vitro to study action potential amplitude and nerve conduction time under varying conditions of Pco(2) and sodium bicarbonate concentration in the surrounding Krebs solution.2. A correlation was found between action potential amplitude and pH but not between action potential amplitude and Pco(2).3. A better correlation was found between conduction time and pH than between conduction time and Pco(2).

The impact of converting to an all frozen blood system in a large regional blood center.

We studied the impact of converting to an all frozen blood system in a large regional blood center. Several basic assumptions were made including the availability of a sterile docking device which would increase the shelf life of deglycerolized blood to 72 hours. Our study indicated that the most economical manner in which to implement such a program would be to supply deglycerolized blood to all hospitals transfusing more than 500 units per year and to provide frozen units to hospitals transfusing less then this amount (those hospitals would deglycerolize the blood they use). The estimated total cost of the proposed conversion was 3.9 million dollars or a 76 per cent increase over the present operation. Relative to our present fee structure, the average cost of a unit of blood would increase 80 per cent if only frozen or deglycerolized red blood cells were distributed.

Failure to confirm specificity of samples containing a very high titer of hepatitis B surface antigen (HBsAg).

Two samples repeatedly positive for HBsAg by the AusRIA II screening procedure failed to be confirmed by neutralization with anti-HBs serum. Both samples could be effectively neutralized by the same anti-HBs sera if diluted 1:10, 1:50 and 1:100 prior to testing. It is suggested that the inability to neutralize was due to a very high concentration of HBsAg in these samples.
