RESUMEN
Phenol and formaldehyde concentrations have been assayed in the air of 125 apartments in newly constructed houses in Bialystok. Xylamide and Solfotox have been used as constmetion materials preservatives in these buildings. Control group consisted of 125 apartments built traditionally. Phenol concentration in the air of the control apartments has not exceeded acceptable values whereas it has been over acceptable values in 80% of the apartments, in which above mentioned preservatives have been used. Formaldehyde concentration in the air of control apartments and 101 apartments of tested group has been within the range of acceptable values. It was much higher in 6 apartments.

The effect on thromboelastogram of normal blood, and activity of platelet factor 3 of gel filtered uraemic platelets were investigated. It was found that gel filtered uraemic platelets cause shortening of "r" time of thromboelastogram and show increased activity of platelet factor 3 (stypven time). Both phenomena were interpreted as being due to increase of platelet procoagulant activity.
