Although malignant transformation of meningiomas has been reported, it is extremely rare in meningiomas of ventricular system. Less than 2% of all meningiomas show malignant transformation from benign meningioma. We report a case of meningioma with early recurrence and malignant transformation and investigated possible underlying factors using immunohistochemistry for PCNA and p53 protein expression.

The facial cleft and duplicated maxilla are lire congenital anomaly. After Rushton and Walker had reported a unilateral facial cleft with excess tooth and bone formation in 1937, few authors described similar cases. The etiology of this anomaly is not well understood, but considered embryologically as a neurocristopathy. A neurocristopathy is defined as a condition arising from aberrations in early migration, growth and differentiation of neural crest cells. This aberrations result in facial malformation such as facial clefts and loss or duplication of facial structures. We experienced a male newborn baby with bilateral facial cleft and duplicated maxilla. The cleft was surgically corrected when he was 5 months old. The function and appearance of lip are improved. Duplicated maxilla will be surgically removed. We report this case with review of literatures.

To investigate the receptors mediating the regulation of norepinephrine (NE) release in human cerebral cortex slices, we examined the effects of opioid agonists for ${\mu}$-, ${\delta}$-, and ${\kappa}$-receptors on the high potassium (15 mM)-evoked release of [$^3H$]NE. [$^3H$]NE release induced by high potassium was calcium-dependent and tetrodotoxin-sensitive. [$D-Pen^2$, $D-Pen^5$]enkephalin (DPDPE) and deltorphin II (Delt II) inhibited the stimulated release of norepinephrine in a dose-dependent manner. However, Tyr-D-Ala-Gly-(Me)Phe-Gly-ol and U69,593 did not influence the NE release. Inhibitory effect of DPDPE and Delt-II was antagonized by naloxone, naltrindole, 7-benzylidenaltrexone and naltriben. These results suggest that both ${\delta}_1$ and ${\delta}_2$ receptors are involved in regulation of NE release in human cerebral cortex.

Including the research in the medical curriculum is regarded as an important issue for medical education. Research experience at medical school has a positive impact on students and it motivates them to undertake further research in the future. The purpose of this study is to explore the factors to activate the research of medical school students. We investigated students' perception of the research curriculum in medical school. The survey for this study was conducted among 41 targeted medical school students from across the Republic of Korea. A total of 370 students from 26 medical schools responded. Benefits through research activities were to study about the areas of interest, as researchers had the opportunity to interact with professors and career. Students, furthermore, had difficulties in research due to data collection, the lack of research space and research funding. Requirements to activate the research were the time to participate in research activities, opening regular research courses, preparation of practical research program and motivation for such research. The medical school would need to improve the medical curriculum through the analysis of the environment and situation the school is facing based upon the in-depth analysis results of what the medical school is pursuing through the research activities, what the students want, what the potential difficulties are, and what the requirements are to improve the research curriculum.
