Nine species of genus Ganoderma different in cultural characteristics each other were separated by histo-anatomical differences. Differences among the species and geographic distribution of G. lucidum were also analyzed to provide the criteria for the classification of Korean cultivation or wild type strains. Korean cultivation and wild type strains were quiet different from other species as well as Taiwan and North American G. lucidum strains in histo-anatomical traits of Ganoderma. Pore color of Korean G. lucidum strains was less brown than those of Taiwan and North American strains. Shapes of pores were round or circular in Korean strains but ellipsoidal or angular in Taiwan or North American strains. Pore numbers of Korean strains were more than those(4~6/mm) of Taiwan or North American strains. Hardness of the pileus of Korean strains was much more than that of Taiwan or North American strains. Such characteristics of Korean strains were different from those of other species of Ganoderma. Korean G. lucidum strains could be classified into the other group because they had many different traits in growth characteristics of fruiting bodies and histo-anatomical characteristics from those of Taiwan or North American G. lucidum and other species of G. lucidum complex.

The authors carried out various treatment modalities in 74 consecutive patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage and were admitted to the Department of Neurosurgery. Konkuk University Hospital, from Jan. 1991 to Dec. 1993. A variety of prognostic factors that influence mortality were observed. The locaton of hematoma was at the basal ganglia in 47 cases and at the thalamus in 27 cases. The prognosis gets poorer as the hematoma extended wider and deeper. The prognosis was unfavorable when the hematoma was over 30cc(P<0.001). The mortality rate was higher in cases with IVH than in cases without IVH(P<0.005). In cases with IVH, 19 cases(26%) showed dilated 4th ventricular hemorrage and higher mortality rate(P<0.001). Cases in which the GCS were less than 9 on admission showed higher mortality rate(P<0.0001). The mortality rate was also higher if the midline shift was more than 10mm on the initial brain CT scan(P<0.005). THe group where the unilateral or bilateral pupillary light reflex was unreactive(35cases) showed poorer prognosis than the group where the bilateral pupillary light reflex was reactive(P<0.0001). The ventriculocranial ratio(VCR), hydrocephalus, surrounding edema edema around the heamtoam, and treatment modality were not related to the prognosis. The significant prognostic factors in patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage were location and type of hematoma, whether or not the volume of hematoma is more than 30cc, IVH, dilated 4th ventricular hemorrhage, Graeb's score of more than 7, GCS of less than 9, midline shift of more than 10mm, and reactivity of pupillary light reflex.

OBJECTIVE: Adult onset Still s disease is an acute systemic inflammatory disorder. There are no pathognomonic symptoms or specific laboratory abnormalities. In recent reports, serum ferritin concentration is increased in active disease phase and decreased after defervescence. Our purpose was to determine the clinical significance of serum ferritin as an indicator for disease activity. METHODS: Seven patients who were diagnosed as adult onset Still s disease at Samsung Medical Center between October 1994 and March 1997, were reviewed. In these patients we checked leukocyte count, ESR, CRP and serum ferritin concentrations at the time of diagnosis and during follow-up periods and recorded febrile events during follow-up periods. RESULTS: At the time of diagnosis and during febrile periods, the concentrations of ferritin were extremely high(927ng/ml to 96,650ng/ml normal 10-290.8 ng/ml). The values were unrelated to other manifestations of the disease or laboratory findings. The ferritin concentrations decreased rapidly after adequate treatment. Eleven febrile reattacks happened in 7 patients. Serum ferritin concentrations were increased in 8 febrile attacks, while leukocyte count, ESR, and CRP were increased in 5, 5, 6 febrile attacks respectively, There were 10 events of increased serum ferritin concentrations in 7 patients during follow-up periods and 8 events were related with fever. The increases of other laboratory tests were similar. CONCLUSIONS: In all patients, serum ferritin concentrations were increased at the time of diagnosis and closely related to fever. During follow-up periods, serum ferritin concentrations are helpful in monitoring disease activity and guiding decisions about treatment.

Chromophobe cell renal carcinoma is an uncommon variety of renal cell carcinoma first described in humans in 1985 by Thoenes and his colleagues. It is a distinct type of renal cancer presumably derived from the intercalated cells of the collecting duct system and exhibiting a better prognosis than other types of renal cell carcinoma. This type of renal cell carcinoma has not been reported in Korean literature. We experienced three cases of chromophobe cell renal carcinoma from surgical pathology files of Dong-A medical center. The patients were a 65-year-old female, a 54-year-old female, and a 50-year-old male who had 8.2x6 cm, 4x2.5 cm and 4.3x3.2 cm sized, yellowish gray, beige to tan colored masses in the kidneys, respectively. Microscopically, the tumor cells were arranged in sheets or nests with delicate intervening vasculature. The cells were voluminous, uniform in appearance and contained finely reticulated cytoplasms delineated by prominent cell borders. With Hale's iron colloid staining the cytoplasm showed positive reaction; with PAS staining the result was negative. Immunohistochemically, the tumor cells showed positive reaction for cytokeratin but negative for vimentin. Electron microscopy showed numerous small, round to oval cytoplasmic vesicles, 150-300nm in size. All the patients received only radical nephrectomy and survived without evidence of recurrence or metastasis during follow-up intervals ranging from 4 months to 5 years.

Although uterine arterovenous malformation(AVM) is a rare cause of menorrhagia or postmenopausal bleeding, it is important to consider that curettage may precipitate life-threatening hemorrhage and therefore it is contraindicated when AVM is suspected. Special investigations such as hysteroscopy, Doppler flow ultrasound and angiography are important diagnostic tools, and transarterial embolization(TAE) has replaced hysterectomy as the treatment of choice in women who wish to retain their fertility. But due to the high incidence of collateral vessels, recurrence of the vascular malformation after TAE is common. We have experienced two cases of AVM, one of which was managed by TAE in combination with surgical arterial ligation.

BACKGROUND: Color Doppler echocardiography is sensitive in detecting mitral regurgitation and useful in quantitating its severity. The presence of an eccentric regurgitant jet suggests that regurgitation is caused by prolapsing or flail leaflet of mitral valve. Until recently the direction of regurgitant jet in mitral valve prolapse has been examined in a single(parasternal short axis view) or orthogonal plane using color Doppler echocardiography, and few in the apical rotation method of a transducer. The purpose of this study was to clarify the usefullness of the apical rotation method of a transducer in detection of the direction of mitral regurgitant jet and diagnosis of the sites of mitral valve prolapse. METHODS: Twenty four patients(8 men and 16 women, mean age:47.3+/-18.8 years) with mitral valve prolapse with eccentric regurgitant jet were examined by two-dimensional and color Doppler echocardiograply using conventional parasternal long and short axis views, and four apical longitudinal planes(four chamber, vertical, two chamber and transverse views) obtained by the apical retation method of a transducer. RESULTS: Thirty one regurgitant jets were detected in twenty four patients, eighteen patients had anterior, nine patints posterior, and three patients bi-leaflet(anterior and posterior) prolapse. In eighteen patients with anterior leaflet prolapse, ten had medial, eight had middle, three had lateral, and three had two portions(two, medial and middle; one, middle and lateral) prolapse. In nine patients with posterior leaflet prolapse, five had medial, three had middle, two had lateral, and one had two(medial and middle) scallop prolapse. CONCLUSION: Color Doppler echocardiography by the apical rotation method of transducer is useful in assessment of the site of prolapse in patients with mitral valve prolapse with eccentric regurgitation.
