[Measurement of exhaust gases of cars in the neighbourhood of roads (author's transl)].

Air samples were collected in plastic bags simultaneously at various measuring points in the close range of streets. When examining the various bag materials, Teflon bags showed the smallest deviations in direct analyses and in analyses of up to two hours after the drawing of samples. The following methods were used for the analysis of the air samples collected in the bags: coulometry for CO and SO2, chemiluminescence for NO/NO2, chromotropic acid for CH2O and flame ionization for hydrocarbon. The various components were measured close to a highway and near streets in residential and business areas.

Serum lipase activity in chronic renal failure.

In a total of 110 patients with chronic renal failure, 46.4% of the cases had a serum lipase activity exceeding 200 IU, the upper limit of the norm. The degree of reduction of renal function is positively correlated to the frequency of hyperlipasaemia as well as to the elevation of the lipase activity in serum. At a glomerular filtration rate (GFR) of less than 20 ml/min, hyperlipasaemia in chronic glomerulonephritis was found in 75%, significantly more frequent than in chronic pyelonephritis (46.8%). The frequency and degree of hyperlipasaemia was not influenced by haemodialysis. Significantly elevated serum lipase activities were also observed in experimentally produced chronic renal failure in the rat.
