Development of an apparatus to measure plasma colloid osmotic pressure mounted on the extracorporeal hemodialysis circuit.

We newly developed an apparatus to measure colloid osmotic pressure (COP) of blood plasma continuously by hemodialysis (HD) or extracorporeal ultrafiltration method (ECUM) without any invasive procedure or blood sampling. The COP value measured by this apparatus highly correlated with the COP value calculated from the concentration of total protein of blood plasma (TP) sampled simultaneously (y = 21.182 + 0.96256x, r2 = 0.911). Measurement of the COP with this apparatus seems to be reliable.

Autologous arterial grafts grown on polyester molds: observations of graft growth and patency in experimental animals.

Tissue molds consisting of polyester mesh jackets covering silicone mandrils were implanted subcutaneously in dogs. When a sufficiently strong layer of connective tissue had formed around the molds they were excised and the mandrils removed. The process of tissue formation was observed and recorded. The forms were used as grafts in either the abdominal aorta or the femoral artery of the dog. Six grafts 10 mm inner diameter, six grafts 6 mm inner diameter and 26 grafts 3 mm inner diameter were implanted. After 4.5 months 80% of the 10 mm grafts, 83% of the 6 mm grafts, but only 4% of the 3 mm grafts remained patent. Histological studies at various intervals after grafting revealed gradual thickening of the neointima. The reason for graft failure was thrombus formation originating at the line of anastomosis.
