A pregnancy is considered postterm if it is beyond 294 days (42 complete weeks). Several investigators have demonstrated that postterm pregnancy may be accompanied by a rise in perinatal morbidity and/or mortality. Abnormalities such as meconium staining, cringenital anomalies, intrauterine growth retardation, postmaturity syndrome, fetal asphyxia have been reported in some cases of reduced amniotic fluid volume (oligohyramnios) which is commonly observed in postterm pregnancies. Amniotic fluid volume has been shown to decrease significantly as gestational age advances beyond term. Oligohydramnios has particular relevance to postterm pregnancies. Poor perinatal outcomes of oligohydramnios on postterm pregnancy have been reported by several authors. To date, however, the relationship between oligohydramnios in pastterm pregnancy and fetal outcome is debatable. The purpose of this clinical study was to evaluate the relationship between oligohydr- amnios and perinatal outcome in 64 cases of postterm pregnancies. Amniotic fluid index(AFI) values were measured semiweekly in 64 good dated, uncomplicated singleton pregnancies. AFI values were categorized into 2 groups. The group 1; patients whose final AFI value was above 5.0 cm; Group 2, patients whose AFI value fell below 5.0 cm. Adverse fetal outcome was defined by the presence of meconium staining, fetal heart rate decelerations, cesarean delivery for fetal distress, low Apgar score at 1 and 5 minutes, neonatal intensive care unit admission, and perinatal mortality. The fetal outcome was compared group 1 with group 2 and results obtained were as follows: 1. The incidence of oligohydramnios in postterm pregnancy was 54.7 %. The average diminution of amniotic fluid index was from 8.2 1.8 cm to 5.6+2.2 cm/week. 2. The incidence of meconium-staining in amniotic fluid was 40.6 % (Group 1: 20.7 %, Group 2: 57.1 %) and showed statistically significant difference between the two groups(p= 0.003). 3. The incidence of Apgar score less than 7 was 23.4% in 1 minute (Group 1: 13.8 %, Group 2: 31.4 %) and 4.7 % in 5 minutes(Group 1: 3.4%, Group 2: 5.7 %), respectively and showed no statistically significant difference between the two groups (p=0.140, p=1.000). 4. I'he incidence of cesarean delivery due to fetal distress was 12.5 % (Group 1: 6.9%, Group 2: 17.1 %) and showed no statistically significant difference between the two groups (p=0.275). 5. The incidence of admission to NICU was 12.5 % (Group 1: 6.9%, Group 2: 17.1 %) and showed no statistically significant difference between the two groups (p=0.275). Adverse fetal outcome was not uniformly observed in postterm pregnancies with oligohydramnios. Amniotic fluid index in oligohydramnios group as a single independent guide was not enough to predict fetal outcomes in postterm pregnancy without specific pathologic condition of fetus.

STUDY DESIGN: Retrospective study of 72 patients treated for the acute lower cervical spinal injury with or without spinal cord injury. OBJECTIVES: We designed this study to evaluate the determining factors in the prognosis of the acute cervical spinal cord injury. We hypothesized as the prognosis is dependent on the severity of injury, not by time-related for the initiation of the treatment. SUMMARY OF BACKGROUND DATA: There is still controversies in the management of the acute cervical spinal cord injury. And the prognosis is generally considered to depend on the severity of trauma to the spinal cord. METHODS: We divided neurologic status into 4 groups; complete, incomplete, root injury and no neurologic deficit group. And there were complete cord injury in 12, incomplete cord injury in 34, single root injury in 14 and no neurologic deficit in 12 patients. The time to operation since injury was 24 hours in 7, 7 days in 32, 3 weeks in 15, 6 weeks in 8, and more than 6 weeks in 5 cases. The operation was indicated mainly for the patients with irreducible fracture-dislocation or for the patients with bony fragments, and disc materials impinging on the spinal cord. Surgical treatment were done in 67 cases with anterior cervical discectomy and fusion(ACDF), ACDF with anterior stabilizaiton, posterior wiring, and circumferential fusion. We statistically analyzed the relationship hetween the time to surgery after injury and the degree of neurologic recovery after surgical treatment by chi square test. RESULTS: There were no neurologic recovery in complete cord injury. There were incomplete cord injury in 34 patients, 8 anterior cord syndrome had no neurologic recovery, among 24 patients with central cord syndrome(CCS) 18(22/24 operated) had neurologic recovery in various degrees and 2 of Brown-Sequard syndrome showed significant neurologic recovery. In nerve root injury, all except l (1/12) patient had complete neurologic recovery. There were neurologic recovery in 2/2 CCS when operated within 24 hours, 8/10 CCS when operated between 2-7 days and 4/5 CCS when operated between 2-3 weeks. There were neurologic recovery in 3/3 CCS when operated between 4-6 weeks and 1/2 CCS when operated more than 7 weeks after injury. There was no significant difference in the relationship between the time to surgery after injury and the degree of neurologic recovery after operation(X2=2.48, df=4, P=0.65). CONCLUSION: Spinai cord injury is directly related with the magnitude of injury at the time of trauma, and the prognosis is determined entirely at the time of injury, And the prognosis is not altered hy time of the treatment.

The influences of adrenal corticosteroid on the development and regression of neurons of dentate and hippocampus were studied by adrenalectomy and steroid overload in neonatal rats. The results obtained were as follows. 1. The cell death occurred naturally in numerous dentate granule cells and hippocampal pyramidal cells. 2. The number of dentate granule cells undergoing cell death decreased by injection of adrenal corticosteroid, but increased in adrenalectomized rat brains. The changes occurred prominently at postnatal day 6. 3. The number of hippocampal pyramidal cells undergoing cell death decreased in CA3 region by injection of adrenal corticosteroid, but was not changed in adrenalectomized rat brains. However, other regions exhibited no change by adrenal corticosteroid and adrenalectomy. 4. The cell death of pyramidal cells of CA3 region occurred in close relationship with the cell death of dentate granule cells, which was different from other CA regions. In summary, the cell death of dentate and hippocampal neurons occurred naturally but seemed to be influenced by other factors as well as adrenal corticosteroid.

The 5 cases of human fetal liver aged from 11 to 23 weeks of gestation were investigated for the ultrastructure of sinusoidal wall by electron microscopy. The endothelial cells deficient in basement membrane formed almost all the part of sinusoidal wall. The cells were continued with neighboring cells by intercellular junction, and overlapped them and exhibited to maintain unfenestrated capillary wall, which was different from those with fenestra in adults. The cells were found to have coated pits on luminal side and several various vesicles in the cytoplasms. The cells were related with transcellular migration of reticulocytes and acidophilic erythroblastes, which penetrated into the endothelial cytoplasm to form transient migrating pore closing after the migration into sinusoidal lumen. The perivascular cells were present at perivascular space and surrounding the sinusoid discontinuously. The Kupffer cells were easily identified with filipodia and lamellipodia and with phagosome of nuclei enucleated from acidophilic erythroblasts.
