Intracranial arachnoid cysts are collections of clear fluid within the arachnoid membrane because of nondisjunction or duplication of the structure. They are rare, represent only 1% of intracranial masses in newborns. Etiologically, they are thought to be due to maldevelopment of the arachnoid or secondary to trauma or infection. The arachnoid cyst by ultrasonogram shows characteristic well capsulated homogeneous hypoechoic cyst. Many arachnoid cysts remain asymptomatic, however, and become symptomatic later in life to cyst growth-resulting in a compression, displacement and irritation of the surrounding structures. So, early diagnosis and treatment of these cysts are important. We present two cases of arachnoid cysts diagnosed in utero by ultrasonogram. In one case, postnatal MRI was checked and confirmed arachnoid cyst with choroid plexus cyst. And other case, postnatal brain USG was checked and diagnosed arachnoid cyst. Both children are asymptomatic, and presents normal development until now. But latter children underwent surgical treatment due to persistent huge cyst and hydrocephalus.

Objective: Purpose of our study was to examine the expression level of 14-3-3 proteins and Bcl-2 family and to estimate the interaction between 14-3-3 proteins and Bcl-2 family in normal and preeclamptic placenta. Methods: Placental tissues were sampled from preeclampsia with caesarean delivery (n=5) and normal pregnant women with caesarean delivery (n=5). Western blot and immunoprecipitation related Western blotting were performed on all placental samples. Unpaired Student t-test was used to determine the statistical significance. Results: Western blot analysis revealed that the expression of Bax and 14-3-3 zeta was significantly greater in the preeclamptic placenta than in the normal placenta. Immunoprecipitation related Western blotting revealed that the interaction between 14-3-3 zeta and Bax was significantly less in the preeclamptic placenta than in the normal placenta. Conclusion: Increased expression of Bax and reduced interaction (between) 14-3-3 zeta and Bax in preeclamptic placenta might influence pathogenesis or sequelae of preeclampsia. Further study is needed to identify the trigger that induces dissociation of Bax from 14-3-3 proteins.
