As liquor contains only HDL (High Density Lipoprotein) as a lipoprotein we have studied the changes in the levels of apolipoprotein A, which is the major component of HDL according to the duration of the pregnancy. The study has been carried out in normal and pathological pregnancies. It has been found that the level of apolipoprotein A rises from the 16th week of amenorrhoea of pregnancy to the 26th week and then gradually drops to term. The maximum level is approximately ten times greater than the level of apolipoprotein A at term (a level approximately of 1 mg per litre). This change parallels that of total proteins throughout pregnancy. We have limited our study in pathological pregnancies to the examination of the liquor at the end of pregnancy. The three pathological maternal conditions that have been most frequently found are:--diabetes,--Rhesus-immunisation,--vasculo-renal syndromes. There has been no significant change shown up in the period that we have studied, which was from the 30th to the 38th week of amenorrhoea.
