Pregnant Yorkshire gilts were utilized to investigate the efficacy of exogenous administration of pST and/or insulin in enhancing prenatal piglet survival, uteroplacental and umbilical cord growth and development. Gilts were randomly assigned in a $2{\times}2$ factorial arrangement to four treatment combinations consisting of either daily i.m. injections of 5 mg pST (P, n=23); 0.50 IU/kg of insulin (I, n=23); combination of pST and insulin (P+I, n=23); or 1 ml of saline as control (C, n=23) from gestation Day 30 to 70. All gilts were sacrificed on gestation d 113 to evaluate piglet survival and uteroplacental or umbilical cord development Uteri were longer (346.3 vs 325.7 cm; p<0.05), and heavier (3122.8 vs 2940.7 g; p<0.05) in insulin treated gilts. Only placental macroscopic surface area was enhanced by maternal insulin injections (p<0.05) Incidence of umbilical cord abnormalities were low (14.3%), and they were independent of maternal treatment, occurring more in short cords than in long ones (21 vs 12%; p<0.05). A 6% increase in cord length (53.2 vs 48.6 cm; p=<0.05) was observed in piglets from treated gilts compared with controls. Significant sex differences (in favour of males) were observed in piglet weight, crown rump length and for most umbilical or placental parameters. Gilt weight gains from breeding to Day 113 of gestation were 10% and 15% greater in pST and insulin treated gilts compared with controls. These data indicate that prepartum injections of pST and/or insulin to gestating gilts seem to have a beneficial effect on uteroplacental or umbilical cord development and promote conditions conducive for perinatal piglet survival.

Abdominal pregnancy is one of the rare but extremely harzardous complications of childbearing. The diagnosis of the abdominal pregnancy is rarely made before surgery and the management of it also has many difficult problems. I experienced a case of abdominal pregnancy developed after the previous unilateral adnexectomy and it was a suspicious primary abdominal pregnancy as though did not fulfilled the Studdiford's the following criteria for primary abdominal pregnancy. 1) normal tubes and ovaries with no evidence of recent or remote injury, 2) absence of any evidence of uteroplacental fistula, and 3) presence of a pregnancy related exclusively to the peritoneal surface and young enough to eliminate the possibility of secondary implantation following primary nidation in the tube. And now I present a case with brief review of literatures.

A successful outcome of pregnancy requires an efficient uteroplacental vascular system. Since this system may be compromised by disorders of haemostasis associated with a prothrombotic state, maternal thrombophilia might be a risk factor for fetal loss. Hereditary deficiencies of the naturally occuring anticoagulants are well recognized conditions predisposing to recurrent venous thromboembolism. Since thrombotic phenomena have been implied as a cause of abortion and stillbirth, these deficiencies might increase the risk of fetal demise. We have experienced a case of antiphospholipid syndrome associated with protein C deficiency in patient with recurrent spontaneous abortion. So we report this case with a brief review of literatures.

This study aimed to report a case of infant who presented with a prenatal ultrasound diagnosis of agnathia, polyhydramnios followed by a review of previous studies. As widely acknowledge, agnathia is a complex lethal malformation characterized by absent mandible, microstomia, microglossia and ear anomaly which are secondary results to a defect of the first branchial auh. Newborn infants with agnathia often suffer from airway obstruction, causing fatal respiratory failure. The most difficult part of treating those newborns is to keep the airway patent. Therefore, as early airway management planning as possible is the most important part. Airway management was achieved with tracheotomy through an ex utero intrapartum treatment procedure(EXIT). The case of this infant, reporting here, was underwent tracheotomy with preservation of uteroplacental blood flow and gas exchange.
