[A method of determining the adhesive properties of sputum].

Adhesive characteristics of the sputum are assessed from adhesion to glass. The force and time of preliminary pressure on the tested material are not taken into consideration, nor is the rate of augmentation of the force directed to disruption of the adhesion contact. The strength of the adhesion contact was found directly depending on the force and time of preliminary pressure and inversely related to disrupting force augmentation rate. A conclusion is made on the necessity of stabilizing work schedules (in reference to the above parameters) for the standardization of the method.
