Studies on the streaming transparency of red blood cell suspension. III. Factors controlling the streaming transparency of suspension.
Materials and methods are essentially the same as detailed in the foregoing paper (Nakamura et al., 1957 a and b), except for the following points. Erythrocytes suspension (0.4% o f cell concentration) : In the Exp. V the concentration of NaCl in media is varied between 0.1 and 1.0 mol gradually. Iodine crystal suspension: Thick alcohol solution of iodine crystal is poured into water stirring gently. Then minute needle-shaped crystals of iodine grow out in the liquid. Crystals of approximately the same dimension are gathered by means of decantation. The concentration of suspensoids is below 1%. Vessel: 36.7 cm of inner diameter. Scattered light measurement o f suspension : The light is received by the multiplyer through a tubelet 1 mm of diameter.
Studies on the streaming transparency of red blood cell suspension. II. Orientation of nonspherical suspensoid in the apparatus.
The curves of streaming transparency (S.T.Curve) which are obtained by the Streaming-transparenciometer (S.T.Meter), reported by the authors in the previous paper (1957), are apparently very different from those obtained by Kuroda (1955) with their apparatus. He attempted to explain the correlation between the orientation of suspensoids and the streaming transparency by the aid of information obtained in his model experience with discoidal paper. The simplicity of the curves of our own encouraged us to investigate the orientation of suspensoids directly by microscope, and it was facilitated by the use of the vessel with a side wall very thin.
