Clinical evaluation of the microporous hollow fiber oxygenator.

This report concerns a clinical evaluation for a newly devised hollow fiber oxygenator, Capiox II. It functions on a one-pump system, and is simple to set up and operate. This equipment was used for 118 patients undergoing cardiac surgery at Tokyo University Hospital from February 1982 through February 1983. The gas transfer capacity proved to be satisfactory. The employment of an air-oxygen blender prevented overoxygenation, and reasonable levels of PaO2 and PaCO2 were demonstrated with a FiO2 0.7, V/Q ratio 0.7 at normothermia. The destruction of platelets was much less with the use of this oxygenator, as compared to findings with the BOS-10. Hemolysis by Capiox II appeared to be lower than that by BOS-10, but the difference was not statistically significant. Differences were distinct in the amount of microbubbles; strikingly, no bubble was evidenced in Capiox II by the ultrasound bubble detector, during general procedures. We conclude that Capiox II is of excellent clinical value, and should be used especially for infants as well as adult patients with possible long perfusions. The merits and demerits of this equipment are given attention.

[A case of alpha-fetoprotein-producing gastric carcinoma with unique macroscopical configuration].

A gastric carcinoma with unique macroscopical configuration was resected from a 63-year-old male patient. Serum level of alpha-fetoprotein (AFP) was markedly elevated (19,000 ng/ml), and AFP-positive cells were found in the carcinomatous tissues. The cytoplasm of the carcinoma cells appeared to be watery-clear by light microscopy, however, electron microscopy revealed abundant amorphous substances in their cytoplasmic matrix. The unique macroscopical configuration of the gastric carcinoma may reflect its biological resemblance to hepatocellular carcinoma. Such a case may be rare, but AFP production, per se, seems to be a rather universal phenomenon of gastric carcinomas.
