Rhinorrhoea plays important roles clinically in diagnosing and treating diseases of nasal and paranasal sinuses.<BR>Using a cone-plate viscometer, which has been said to be capable of expressing the properties of non-newtonian fluid such as rhinorrhoea most accurately, the viscosity of rhinorrhoea was determined in 300 cases, in 71 of which biochemical analysis was also carried out, with following results.<BR>1) At shear rate of less than 19.2 sec<SUP>-1</SUP>, the apparent viscosity of rhinorrhoea elevated rapidly, showing thixotropy phenomenon, pseudoplasticity and structural viscosity. The viscosity curve displayed a hysteresis loop.<BR>2) The presence of yield value was confirmed in rhinorrhoea, with a mean of about 56 dyn/cm<SUP>2</SUP> by Cone's ascending order as studied in 300 specimens in this study.<BR>3) The viscosity of rhinorrhoea was found to be related to total protein, calcium, and water content, with especially close relations with the former two parameters.<BR>4) Findings of maxillary X-ray membrane function test revealed that the better the excretory function is, the lower becomes the apparent viscosity of rhinorrhoea retained in the maxillary sinus.
