This paper describes enzyme studies in normal and abnormal pregnancy. Urinary @entity368 @entity2965 (L.A.P.) excretion remained relatively low throughout normal single pregnancy. Urinary L.A.P. excretion was, however, raised towards term in four out of five cases of multiple pregnancy, but in one @entity1 the predelivery urinary L.A.P. was not raised, and the second twin in this case died shortly after delivery with gross @entity154 . Urinary L.A.P. was also investigated in ;high-risk' @entity1 . One such @entity1 had excessive loss of this enzyme throughout pregnancy, and in the discussion it is suggested that this could be due to excessive loss of @entity50799 in the urine. @entity1 with toxaemia were assessed on the basis of foetal survival and the maximum 24-hour pre-delivery urinary levels of @entity368 @entity2965 . This urinary value could not be used to predict foetal outcome, but rose to over 120 mg. @entity27839 per 24 hours in the presence of frank @entity644 . If intrauterine @entity204 occurred, the urinary L.A.P. value fell gradually. Urinary L.A.P. was also elevated in essential @entity101 towards term, but in these @entity1 there was no gross @entity644 .
