[Medium weight molecules in patients with external genital endometriosis].

One hundred and fifty-three women with external genital endometriosis (EM), stages 1-4, and 30 healthy fertile women were examined. The peripheral-blood serum and daily urine were tested with the level of the mean weight molecules (MWM) being determined spectrophotometrically at lambda = 230-300 nm. The minimal MWM concentrations were detected in blood in cases of the stage-1 endometrioid process; they were significantly lower versus those observed in the healthy women at the maximal urine concentrations, i.e. well above the normal value. An increasing MWM blood content is registered in stages 2-4 EM, which exceeds the normal figure, whereas MWM was minimal in urine in stage 2, it was progressively increasing later but did not reach the value of stage 1. The external EM was associated with an enhanced MWM formation; it is noteworthy, that their concentrations in blood serum directly correlated with a stage of the endometrioid process. A reliably lower MWM level in stage 1 EM is below the normal value, while its maximal increase in urine could be regarded as a compensation-adaptation reaction aimed at removing the toxic substances from the body. A reduced MWM discharge with urine and its growth in blood plasma were observed in further progressing of the endometrioid process, which is preconditioned by the toxic impact of MWM exerted on the nephron.
