We report on 19 cases of intracranial germ cell tumors, including 12 male and 7 female patients; the average age was 16.5 +/- 4.9 years. These tumors included germinoma in 15 cases, yolk sac tumor in 3 cases, embryonal cell carcinoma in 1 case, and mixed tumor in 3 cases. Each of 5 cases had 2 to 3 different kinds of tumor cells, either in one tumor or in(More)
The mechanism by which intracerebral hemorrhage leads to the formation of brain edema is unknown. This study assesses the components of blood to determine if any are toxic to surrounding brain. Various solutions were infused stereotactically into the right basal ganglia of rats. The animals were sacrificed 24 hours later; brain edema and ion contents were(More)
We evaluated radiologic and clinical outcomes to compare the efficacy of anterior cervical discectomy and fusion (ACDF) and anterior corpectomy and fusion (ACCF) for multilevel cervical spondylotic myelopathy (CSM). A total of 40 patients who underwent ACDF or ACCF for multilevel CSM were divided into two groups. Group A (n = 25) underwent ACDF and group B(More)
The activation of coagulation, angiogenesis and inflammatory cytokines are considered to be related with tumour growth and metastasis. We investigated the plasma levels of platelet microparticles (PMP), vascular endothelial growth factor (VEGF), IL-6, and the chemokine RANTES in patients with gastric cancer (n=109) and in healthy controls (n=29). The plasma(More)
Herniography is an accurate means of identifying groin hernias when the clinical diagnosis is uncertain. Its role in evaluation of other types of ventral hernias is less clear; however, with minor modifications in technique, herniography is also useful in these cases. This article reviews the technique of herniography, normal variations in anatomy, and(More)
STUDY DESIGN.: Retrospective study. OBJECTIVE.: To compare the efficacy of anterior cervical discectomy and fusion with cage alone (ACDF-CA) with cage and plate construct (ACDF-CPC) in regards to fusion rate, radiologic and clinical outcomes. SUMMARY OF BACKGROUND DATA.: ACDF-CA has shown good results; however, debate exists regarding the high rate of(More)
Mucinous ovarian neoplasms other than cystadenomas and adenofibromas have been classified as either borderline tumors or carcinomas for many years. Borderline tumors have been subdivided more recently into endocervical-like (mullerian) and intestinal forms. Such a distinction is rarely made in the mucinous carcinoma category. We did not encounter a pure(More)
BACKGROUND To determine the clinical and pathologic prognostic factors in surgically treated patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB-IIA small cell neuroendocrine carcinoma of the uterine cervix (SCNEC). PATIENTS AND METHODS We retrospectively reviewed a total of 68 patients with FIGO stage IB-IIA SCNEC(More)
The purpose of this study was to determine the annual incidence of Perthes' disease in Korea and compare this with other populations. A survey identified all newly diagnosed children with Perthes' disease aged 14 years or younger in South Honam, Korea, between January 1999 and December 2001. A total of 84 children were included: 29 in 1999, 28 in 2000 and(More)
Three new butanolides, 2-(1-methoxy-11-dodecenyl)-penta-2,4-dien-4-olide (1), (2Z,3S,4S)-2-(11-dodecenylidene)-3-hydroxy-4-methylbutano lide (2) and (2E,3R,4R)-2-(11-dodecenylidene)-3-hydroxy-4-methoxy-4-methylbu tanolide (3), were isolated from the stems of Lindera obtusiloba BLUME. Their chemical structures were assigned by spectroscopic evidence. They(More)
