The Polyporaceae is a chaotic mass of genera having poroid hymenophores in the Aphyllophorales. To classify the Polyporaceae into more natural groups, phylogenetic analyses were performed using nuclear small subunit ribosomal DNA sequences. Thirty-six species from the families of the Polyporaceae, the Hymenochaetaceae, the Ganodermataceae, the Corticiaceae, the Bondarzewiaceae, the Meruliaceae, the Steccherinaceae and the Lentinaceae were phylogenetically compared. By performing maximum parsimony analysis, seven phylogenetically meaningful groups were identified and discussed. The hyphal system, presence or absence of clamps, and the type of rot were found as important characters in defining the groups. Each group was phylogenetically significant enough to be a core member of each family when the Polyporaceae was split into smaller and more natural families.

To evaluate the establishment of Mungyong Saejae Natural Ecology Park located in the northwestern Gyongbuk Province, a scientific survey for the mushroom flora of the park was carried out from May to December of 1999. A checklist of the Aphyllophorales collected from the park was prepared. The list included 67 species of 44 genera belonging to nine families in the Aphyllophorales. Among them, seven species, Antrodia malicola, Ceriporia purpurea, Oligoporus leucospongia, Perenniporia tephropora, Phanerochaete xerophila, Sistotrema diademiferum and Vuilleminia comedens, were confirmed as new to Korea and are registered here as unrecorded species along with descriptions and microscopic drawings.

Although there are differences in the mode of onset, symptomatology and clinical course in the various types of cerebrovascular lesions, the general picture may be quite similar and it is often difficult to determine the nature of the lesion in any individual case from the clinical data. In the vast majority of cases the symptoms of a cerebrovascular accident are of sudden onset and reach maximum intensity within few minutes or a few hours at the most. Locksley, et al. have reported autopsies on people who died from spontaneous intracerebral or subarachnoid hemorrhage, and they found that a primary or metastatic brain tumor was the cause of hemorrhage in only 2%~3% of their necropsy. We presented our experience with two such patient whose clinical pictures before the surgery were quite similar with those of cerebrovascular accident. Cases with a large chronic subdural hematoma and cerebral glioblastoma multiforme demonstrated a sudden and dramatic onset of coma and focal neurological symptoms immediately before admission to the hospital. The responsible mechanism or etiology for the mode of such sudden dramatic onset of symptoms may be derangement of intracranial pressure mechanism and sudden hemorrhage in the tumor.

The most feared complication of left ventricular thrombus (LVT) is the occurrence of systemic thromboembolic events, especially in the brain. Herein, we report a patient with severe sepsis who suffered recurrent devastating embolic stroke. Transthoracic echocardiography revealed apical ballooning of the left ventricle with a huge LVT, which had not been observed in chest computed tomography before the stroke. This case emphasizes the importance of serial cardiac evaluation in patients with stroke and severe medical illness.

BACKGROUND: Almost 50% of infants born to mothers with preeclampsia have neutropenia and are at increased risk of having early-onset sepsis and nosocomial infection. In neutropenic children, recombinant human granulocyte colony-stimulating factor(rhG-CSF) increase circulating neutrophils and bone marrow neutrophil storage pools, improves neutrophil function, and results in fewer bacterial infections. We examined circulating neutrophil counts after administration of rhG-CSF to neutropenic neonates of mothers with preeclampsia. METHOD: Subjects were selected from premature(gestational age<36 weeks) and low birth weight infants(<2,500 g) born with preeclampsia at the St. Mary's Hospital between January, 1996 and July, 1997. The rhG-CSF was administered as an subcutaneous injection, 10 microgram/kg per dose. The first dose was given before 24 hours of age, and the medication was given at 24-hour intervals for three doses. We selected control infants with matched subjects for gestational age and birth weight with normal neutrophil count. Results: 1) Initial WBC counts of the study infants, obtained at birth-day, were not significantly different from the WBCs of study infants(t-test. P>0.05). 2) Absolute neutrophil counts(ANCs) in rhG-CSF-treated infants at 24, 48 and 72 hours of age were significantly higher than initila ANCs at birth(P<0.05). 3) ANCs in control group at 24 and 48 hours of age were not significantly different from initial ANCs at birth(t-test, P>0.05), but significantly lower at 72 and 96 hour of age(t-test, P<0.05). 4) ANCs in rhG-CSF treated infants at 24 and 48 hours of age were significantly higher than those in control group(P<0.05), but at 72 and 96 hours of age, there were not significant difference between ANCs in treated infants and those in control group(P<0.05). Conclusoin: rhG-CSF promote a rapid increase in circulating neutrophils in netropenic low birth weight infants of mothers with preeclampsia.
