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.

IVRO is one of the most common procedures to setback prognathic mandible. Since 1993 we have set-up our own protocol for functional physiotherapy(Park's protocol) after IVRO. This is a study on openbite and relapse tendency after IVRO followed by our protocol. We obtained lateral cephalograms of twenty-seven patients which were taken immediately after surgery, 3 months, 6 months and 1 year postoperatively. Changes in positions of each point were analyzed. The results were as follows: 1. No remarkable openbite occured during the first year after IVRO. Upper teeth, lower teeth and anterior mandible moved upward, it seems to show that post-op orthodontic treatment did not contribute to reduce openbite tendency during post-op period. Rater, the lower teeth and mandible moved with the upper teeth as the compensation mechanism. 2. Lower Incisal Edge moved anteriorly up to 6 months, so overjet decreased from 3.3mm to 2.9mm during the first six months. Skeletal changes in anterior mandible showed slight anterior movement, therefore showing slight relapse tendency, but it represented no statistical significance. 3. The physiotherapy according to our protocol was used for only a month after operation, but there was no openbite tendency, and the occlusion was stable over one year.

The hyperosinophilic syndrome (HES) commonly involves liver and spleen but only a few literature has reported the imaging features. In this article, we present the imaging features of the liver and spleen in HES patients together with clinical and laboratory features. This study included 5 HES patients with hepatic involvement. Extensive laboratory tests including multiple hematologic, serologic, parasitologic, and immunologic examinations were performed. Imaging studies included CT, ultrasound (US) of upper abdomen and hepatosplenic scintigraphy. All patients were periodically examined by laboratory and imaging studies for 4 to 24 months. The common clinical presentations were weakness, mild fever, and dry cough. All patients revealed leukocytosis with eosinophilia of 40 to 80% and benign eosnophilic hyperplasia of the bone marrow. The percutaneous biopsy of the hepatic focal lesions performed in 2 patients showed numerous benign eosinophilic infiltrates and one of them revealed combined centrilobular necrosis of hepatocytes. All cases revealed hepatomegaly with multiple focal lesions on at least one of CT, US, or scintigraphy. These findings completely disappeared in 2 To 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphy. These findings completelydisappeared in 2 to 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphic studies showed hepatic multifocal lesions with hepatomegaly. Differential diagnoses of these findings should include metastatic disease, lymphoma, leukemia. candidiasis or other opportunistic infections.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.
