    PVC resin now generally used for medical applications contains di-2-ethylhexylphtharate (DEHP) as a plasticizer. There have been many reports presenting the fact that DEHP migrates from dialysis circuits and blood bags made of PVC resin into blood as it is extractable by the lipid in blood. DEHP migrates because it just dwells in the resin as a low molecular weight substance without chemical bonding with polyvinyl chloride. A new PVC resin plasticized with a special polyurethane has been developed for such medical application as dialysis circuits and blood bags, from which the plasticizer is never extracted because it is a high polymer and setangled with polyvinyl chloride in the resin.
    The new PVC resin(PU-P) was used clinically for 18 patients and no other extracts were detected in the sera of the patients and no abnormality was observed in other chemical labolatory findings and CBC. On the other hand, 224-666 ppb of DEHP were detected in all of the patients for whom conventional PVC resin (DEHP-P) was used and DEHP-accumulation were observed in lung, liver, kidney, spleen, pancreas, adipose tissue and muscle in two autopsy cases of the dialysis patients treated with DEHP-P.
    No practical problem was observed about durability of the roller pump part, flexibility of time of the tubes and blood coagulation in the circuit of PU-P and no clinical sympton was found in the patients treated with PU-P.

    P wave duration and amplitude in the standard limb lead II and P wave terminal force (Ptf) in the chest lead V1 were measured before and after pacemaker implantation in the patient with atrioventricular (A-V) block and sick sinus syndrome.
    PII amplitude and negativity of Ptf were observed to be increased in the patient with A-V block. There was found a significant relationship between Ptf and cardiothoracic ratio (CTR) in the chest X ray of the patient with A-V block. After the implantation of pacemaker, negativity of Ptf in the patient with A-V block decreased.
    From these findings, it can be said that the patient with A-V block had atrial overload due to hemodynamical restriction partly as the result of low heart rate and physiologically abnormal correlation of atrial and ventricular contraction, and that it was improved after pacemaker implantation.

    Three homopolyamino acids, three random copolyamino acids, and eight kinds of A-B-A type block copolymers were synthesized. Those were coated on the mesh cloth of polyester fiber, and implanted subcutaneously in rabbits for 4 weeks. The biocompatibility of polymer samples was evaluated by observing microscopically the tissue reaction. Homopolyamino acids and random copolyamino acids other than poly-D, L (1:1)-amino acid showed low degree of foreign body reaction. The biocompatibility of block copolyamino acids composed of polyamino acids as the A component and polybutadiene as the B component was dependent on their microheterophase structure in the membrane. The A-B-A block copolymers composed of polytetramethyleneoxide as the B component had good biocompatibility.
