As to the change of factors relating to the plasmin system during pregnancy and puerperium, some conflicts have been found in the literature. This paper deals with the results of systemic analysis of this enzyme system, and the relation be tween sex hormones and the factors is discussed. A marked elevation of factors of plasmin system during pregnancy was observed in fibrinogen, spontaneous cas...

THIS STUDY OF MATERNAL MORTALITY IN OMAN TRIES TO ANSWER THE QUESTION: Is the Fifth Millennium Development Goal achievable in Oman or not? In Oman, Maternal Mortality Ratio currently stands at 22.9/100,000, a reduction of 38.9% from its 37.5/100,000 in 2002. This figure suggests that much needs to be done to accelerate progress towards the achievement of the Fifth Millennium Development Goal. C...

Maternity Service, I found his article disappointing in the inadequacy and impractica-bility of his suggestions. The traditional relationship between doctor, patient and consultant has proved over a long period to be too valuable to all concerned to be lightly discarded. Competition between doctor and consultant for patients destroys this relationship utterly. Professor Lennon wants all patient...

Oxytocin, a hormone involved in numerous physiologic processes, plays a central role in the mechanisms of parturition and lactation. It acts through its receptor, which belongs to the G-protein-coupled receptor superfamily, while Gq/phospholipase C (PLC)/inositol 1,4,5-triphosphate (InsP3) is the main pathway via which it exerts its action in the myometrium. Changes in receptor levels, receptor...

It is well known that a low level of circulating fibrinogen may be associated with bleeding in a variety of obstetric complications, as, for example, accidental haemorrhage. The actual cause, however, ofthe depletion offibrinogen in these conditions is debatable (Moore, 1955), but one feature of such states is the frequent presence of a circulating proteolytic agent which is capable of destroyi...

THE marked changes in hormone production in pregnancy are associated with changes in metabolism and function. Much of the work which has been done and is being continued in the Clinical Research Unit of this department is concerned with the changes in body composition in normal and abnormal pregnancy and the puerperium and in the uterine activity in la;bour. The earlier endocrine work had been ...

In the United States, the annual rate of preterm births (before 37 weeks of gestation) reached a peak of 12.8% in 2006 and was 11.7% in 2011.1 The rate in the United States remains nearly twice the rate in European nations.2 Premature birth in the United States accounts for 35% of deaths in the first year of life3,4 and estimated annual costs exceeding $26 billion.5 Rates of death in the first ...

Total cortisol and progesterone in the maternal peripheral sera were determined by radioimmunoassay. Total cortisol was measured in 196 sera, and progesterone in 203 sera obtained randomly throughout pregnancy. And serial estimations of both steroid hormone levels were also made simultaneously in 6 normal pregnant women during late pregnancy, labour and puerperium. Total cortisol and progestero...
