Leukocyte adherence initiation in skeletal muscle capillaries and venules.

In vivo leukocyte adherence has many physiological implications but the effect of vessel size and hemodynamic parameters on adherence initiation remains unclarified. The early phases of adherence, defined to include attachment of previously freely moving leukocytes to endothelium or leukocytes which roll along the vessel wall, are the focus of this report. Blood velocity and diameter in 121 capillaries and venules in the cremaster of 13 rats were measured.

Effects of prolonged administration of high molecular levan on hematological parameters in rabbits.

Rabbits were injected intraperitoneally with 100 mg of high molecular levan, daily for 4--6 weeks. Study of various hematological parameters revealed that the treatment resulted in the following changes: 1. Marked elevation in fibrinogen levels and in the number of platelets.

Effects of prolonged administration of high molecular levan on arterial blood gases, oxygen transport and acid base balance in rabbits.

The effect of daily intraperitoneal injections of 100 mg of high molecular levan for 4-6 weeks on a number of physiological parameters was studied in rabbits. The parameters studied included whole blood pH, blood gases and acid-base balance. Control rabbits were similarly treated with physiological saline.
