Encephalocele is a relatively rare congenital anomaly which is classified into occipital, parietal, anterior syncipital and anterior basal type regarding to the protrusion site through the bony defect of the skull. Anterior basal type of encephalocele is important in view of it's pathogenesis as well as diagnostic difficulty because of invisibility on external appearance. We have experienced a case which could be best fit to anterior basal encephalocele. This type of encephalocele is extremely rare. This report deals with a case of deadborn of 34 weeks of gestation with body weight of 2400gm and head circumference of 32 cm. There was no evidence of protrusion of brain on external examination. On autopsy the normal brain structure was compressed by abnormal mass of brain with normal consistency which was found in the petrous portion of the parietal area and covered partly by the dura. In this case, there were another associated anomalies, such as atrophy of the left optic nerve, hemihypoplasia of the left mandible, patent ductus arteriosus, bilateral hydrocele, and Meckel's diverticulum.

As increasing concern for the fetal aspects of pregnancy, the availability of normal standard of placenta becomes more and more important. because it is very difficult to test the functional capacity of placenta. And for this reason anatnmic studies to determine the normal relationship between the placenta and newborn infant have come to be a considerable importance. A study of morphometric features of 4,000 consecutive placentas delivered at the Seoul National University Hospital during a period of 3 years, from April 1979 to May 1982, in relation to gastational age and weight of newborn was carried out. The findings could be summarized as follows: 1) Among 4,000 consecutive deliveries there were 3,771 liveborns 76 deadborns, and 153 cases of abortion, respectively. 2) The average weight and dimensions of term placenta were 511 gm and 19.94 x17.09 x1.89 cm, respectively. The weight , size and volume of placenta were progressively increased from 20 weeks of gestation till 41 weeks. 3) Morphometric features of placenta such as placenta weight, dimension, fetoplacental ratio and placental co-efficient showed a more significant correlation with birht weight than with gestation age. 4) The average length of umbilical cord was 39.80 cm, with the range of 6 cm to 124 cm. 5) The congenital anomalies of newborn was encountered in 74 cases (1.85%) among 4,000 consecutive deliveries. Anomalies involving musculoskeletal system was the most common oen. 6) The abnormal gross findings among 4,000 consecutive placentas included 6 cases of single umbilical arteries, 4 cases of chorangioma, 545 cases of infarction and 748 cases of calcification.

Injuries to the pelvic nerve plexus following major pelvic ablative surgery are commonly observed conditions in urologic field and often related to voiding difficulty with flaccid type of neurogenic bladder. The pathophysiological background for voiding difficulty is unknown and also it is difficult to investigate in human. The present study was undertaken to investigate the functional changes on the bladder and urethra in major pelvic ganglion denervated rats (experimental group). Injury to the pelvic nerve plexus was created by selective removal of bilateral major pelvic ganglions of mature Sprague-Dawley rats (male, 250-300 gm). One week after operation, urodynamic evaluation and NADPH diaphorase histochemistry were performed in each rat. The whole bladder wet weight and residual urine of experimental group significantly increased to 1.6 times and 29 times that of control group, respectively. For urodynamic investigations, the bladder and the urethra were completely disconnected by means of ligation between the bladder neck and the proximal urethra, and simultaneous recordings of the intravesical and proximal urethral pressure were performed. During simultaneous urethro-vesical filling in experimental group, vesical contraction and urethral relaxation were not induced. However, an administration of L-arginine (120 mg/kg intravenously), a nitric oxide substrate, resulted in a gradual decrease in urethral pressure when the bladder pressure was reached at submaximal level. On NADPH diaphorase histochemistry in control group, a large number of NADPH positive nerve fibers were found in the proximal urethra, whereas those were found less commonly in the bladder. In experimental group, the number of NOS positive nerve fibers in the bladder was similar to that in control group. But in the proximal urethra, the number of NOS positive nerve fibers (84.7 +/- 12.7) decreased significantly in contrast to that (185.9 +/- 56.3) in control group. These results indicate that failure to empty in neurogenic bladder may be resulted from relaxation impairment of bladder outlet, which can be explained by the reduction of neuronal NOS in the proximal urethra in experimental group.
