We report the case of a 33-week-old female fetus born with craniorachischisis to a gravida 5, para 4 (3104) mother with no previous history of conceiving a child with a neural tube defect. Craniorachischisis is characterized by anencephaly and an open defect extending from the brain to the spine and is the most severe and fatal type of neural tube defect. Although the cause of neural tube defects is hypothesized to be multifactorial and is usually sporadic, the risk is increased in neonates born to mothers with a family history or a previous pregnancy with neural tube defect, both of which are not present in the index case. This case is unique in that only during the fifth pregnancy did the couple conceive a child with a neural tube defect, emphasizing that folic acid supplementation, the sole preventive measure proven to decrease the risk of neural tube defects, remains to be important in the periconceptual period for all women of childbearing age.

A sex determination method has been developed using the polymerase chain reaction (PCR) which involved the amplification of sex determining region Y (SRY) gene and the amplification of the HLA-DQ gene as an internal control, in the one PCR reaction using two sex of the primers. The PCR products were sort ADN of 139 bp for SRY and 239/242 bp for HLA-DQ region spectively. The amplification of this method in prenatal diagnosis to prevent genetic diseases, in forensic science.

In this study, serum samples collected from 48 high-risk pregnant women were screened for three markers: alpha-feto protein (AFP), beta-human chorionic gonadotropin (b-HCG) and conjugated estriol (UE3) to define the risk of congenital aneuploidy and neural tube defect...The result showed the serum AFP level raised in two cases (more than 2.5MoM - Multiple of Median). One case has decrease in AFP (less than 0.06MoM) combined with decrease in UE3. Once has decrease in AFP (less than 0.06mOM) combined with increase in b-HCG. One case has decrease in AFP (less than 0.06MoM) combined with decrease in UE3 and increase in b-HCG level. One case has decrease in AFP alone (less than 0.06MoM). Fetal neural tube defect was identified in one case. Other four cases have increase in b-HCG only. these pregnancies should be referred to genetic study and further tests.

Myelodysplasia syndrome is a diseases group of which quite difficult cure and prediction. There are many treatment methods however it depends on patient’s age, level of diease, rate of blast in bone marrow. The treatment includes: chemical treatment, trasplant originative cell, support treatment. Other method is combination of various treatment methods: Use Ara-C combine with depersolon, chemical treatment combine with stimulative agent of blood and trasplant originative cell

A case of neurenteric cyst within the cervical canal is reported. He has been suffered from gradual aggravated quardriparesis since 4 months. On spine C-T scan and cervical myelographic examination, intradural extramedullary mass was detected. And so total laminectomy of C4, C5 and C6 was performed. We could diagnose by the pathological findings.

OBJECTIVE: To determine whether there is a re-closure capacity of the open neural tube defect(ONTD) and to characterize its re-closing process, the morphological changes and the re-closure rate of a surgically induced ONTD are examined chronologically in early chick embryos. METHODS: Embryos of Hamburger and Hamilton stage 18-19 were used. The posterior roof of the central canal in the closed neural tube was incised longitudinally at the wing bud level. The incision was 3 somites long, which was equivalent to approximately 0.8mm. Following surgery, the embryos were re-incubated in ovo for three or five days. The area of the incision was observed with a stereomicroscope. Some of them were examined histologically with the transverse section of the wing bud area. They were divided into two groups(POD 3 and POD 5) according to the re-incubation period at the time of sacrifice and then into two subgroups(re-closure and defect group) according to the presence of ONTD at the operative site. RESULTS: The results showed : 1) Re-closure of ONTD occurred in 58%(23/40) of POD 3 embryos and 46%(22/48) of POD 5 embryos. The difference of re-closure was not statistically significant. 2) Most of the re-closed neural tubes revealed no significant difference from the controls in the histological examination. 3) In POD 3 and 5 groups, there was a tendency of zipper-like fusion in both re-closure and defect groups. CONCLUSION: The results of study showed that the neural tube of the early chick embryo has a re-closure capacity after being surgically reopened. Seemingly, re-closure occurs mainly before POD 3 and progresses from the ventral to the dorsal part of the neural tube. The mechanism of re-closure needs to be investigated further.
