PURPOSE: To determine the role of Tc-99m HMPAO SPECT imaging in children with intractable seizure by evaluating the interictal period. METHODS: We compared the EEG, CT and MRI medical records with those of Tc-99m HMPAO SPECT in 42 patients with intractable seizure referred to Kyunghee University Hospital, from April 1983 to September 1998, retrospectively. RESULTS: Mean age was 8.3 years and male to female ratio was 2.5 : 1. Multiple surface EEG recordings were performed in 42 patients and EEG findings of all patients showed an epileptogenic focus, with the most common area of abnormal findings being the Lt. sides. Brain CT was performed in 23 out of 42 patients(54.8%), and 15 out of the 23 patients(65.2%) showed abnormal findings and the most common area of abnormal findings were both sides. Brain MRI was performed in 21 out of 42 patients(50.0%), and 14 of the 21 patients(66.6%) showed abnormalities and the most common area of abnormal findings were both sides. In 32 out of the 42 patients (76.2%), SPECT images showed abnormal cerebral perfusion, most common area of hypoperfusion were Lt. sides. In 10 out of 14 cases, there were lateralizing abnormalities on the same side shown in SPECT and EEG, CT or MRI findings. CONCLUSION: We concluded that Tc-99m HMPAO SPECT seemed to be a useful tool in the evaluation of intractable seizure patients.

Osteosarcoma is one of the most common malignant bone tumors except for multiple myeloma. The current managements of the osteosarcoma patients include preoperative chemotherapy, definitive operation and postoperative chemotherapy with tremendous improved oncologic results by lots of Orthopedic Oncologists. The definitive operations are either limb-salvage operations or amputation. Limb-salvage operations include autograft, allograft, tumor prosthesis, or its combination. However, we have a difficulty to use allograft due to Korean traditonal customs. Authors managed the 6 year-old female patient with the osteosarcoma on the proximal metaphysis of the right humerus by wide-margin resection and reconstruction with a clavicula pro humero procedure with an excellent result, which technique was devised and developed by W. Winkelmann in Germany.

The osteopoikilosis is commonly known as harmatoma in which metaphyseal and epiphyseal area of long bones and the bone of pelvis, hands, feet and et al, contain islands of dense cortical bone with normal Harversian system without any symptoms. The radiologic findings of the osteopoikilosis is multitude of oval or well-circumscribed areas of increased density, 2 to 10 mm in size, in symmetrical distribution and normal uptake in bone scan. Buschke-Ollendorff syndrome, which is transmitted by autosomal dominant, is characterized by the association of osteopoikilosis and connective tissue nevi which are popular and symmetrically distributed lesions on chest, back, buttock, thigh or arm. Authors report three Buschke-Ollendorff syndrome, studied by CT scan, MRI, bone scan and bone and skin biopsy, among five patients associated with osteopoikilosis found by simple radiologic study from ten members in one family with their pedigree.

The effects of hind-limb immobilization by skeletal fixation of bilateral ankle and knee joints. for sither one or five weeks on glycogen concentrations, glycogen resynthetic activities and insulin responses to glucose uptake of hind-limb muscles were studied on male Splague-Dawley rats. There were significant drops in muscle wet weight to body weight ratio of immobilized soleus and plataris. In the group immobilized for one week, the ratios of sleous and plantaris were decreased by 11% and 38% respectively; and in the group immobilized for five weeks, the ratios were decreased by 42% in both muscles equally. The glycogen concentration and glycogen resynthetic activities of soleus and plantaris muscles in immobilized rats were decreased significantly in the one week group. However, in the five week group, these values were increased significantly compared to the values of those muscles of the one week group. The increased values of the five week group did not exceed those of the control group. The glucose uptake rate of the soleus muscle of the hind-limbs immobilized for one week and for five weeks were studied in vitro. The basal glucose uptake rate of the muscle of the control group was 8.4 ± 0.77Mol/gm/20min. The values of basal rate and insulin responses to the glucose uptake rates in the doses of physiological and supramaximal on the soleus muscles immobilized for one week was significantly decreased, but after immobilization for five weeks, these values were not significantly different statistically those from of the control group statistically.

Protein Kinase C (PKC) relays information in the form of a various extracellar signals across the membrane and is known to play an important role in the production of B lymphocytes and T lymphocytes, in the antigen-presentation of Langerhans cell, and in inflammatory reactions. The presentation of allergens to T lymphocytes is likely an important aspect in the pathophysiological mechanism of allergic rhinitis. Although several theories have been formulated in allergic rhinitis, signal transduction of this disease remains unknown. In this study, we focused on the role of the enzyme PKC in the allergic mucosa of the nose. Specifically, we investigated the role and the distribution of PKC isozymes in the mucous membrane of the nose. We obtained nasal mucous membrane specimens from 10 patients with house dust mite allergy and 10 patients with normal nasal mucous membrane. We performed an immunohistochemical study, an RT-PCR, and a densitometric measurement. PKCalpha, PKCbeta, and PKCzeta proteins were detected in the subepithelial layer of the allergic mucosa. However there were no detectable reactions in the nonallergic mucosa. In the RT-PCR for PKCalpha, PKCbeta and PKCzeta, there was no difference between the allergic and nonallergic nasal mucous membrane in terms of m-RNA expression. It is possible that the signal transduction pathway of PKC and over-expression of PKC protein at the post-transcription level contribute to the development of allergic inflammation in allergic nasal mucosa.

BACKGROUND AND OBJECTIVES: Abundance of Japanese cedars (JC) in Cheju Island has caused some of the island's residents to suffer from severe allergic symptom in the spring time. This study was carried out to verify the presence of JC allergic rhinitis (AR) in the island. Materials and Method: We performed a history survey, skin testing and nasal provocation test to JC and other common allergens for 170 residents who have symptom of AR. We also performed the same tests in 18 Japanese who had history of AR to JC and have lived in Korea more than 3 years. And as a control, skin tests were performed for 581 patients who live in Seoul. RESULTS: Positive reactions to JC were seen in 22.4% of the resident group. The prevalence rate was remarkable in the state capital of Cheju. These reactions were associated with conjunctivitis, dermatitis, asthma and food allergy. All the 18 Japanese patients were sensitive to JC. However, the allergic symptoms disappeared within 1 year after the move to Korea. And there were no patients sensitive to JC in the control subjects. Conclusions: We confirmed the presence of AR of JC in Cheju island. The distribution is comparatively coincided with JC and/or air pollution and this result indicate that environmental factors can be involved in the manifestation of the disease.

BACKGROUND AND OBJECTIVES: Retinoids have recently become an interest to clinicians because of their ability to inhibit migration and proliferation of the premalignant squamous cells, while enhancing growth and proliferation of normal cells. Aural cholesteatoma is defined as the state of hyperproliferative keratinocytes in the middle ear cavity. An in vitro investigation was undertaken to determine whether all-trans retinoic acid (t-RA) exhibits an inhibitory effect on cholesteatoma cell proliferation. METHODS: Cholesteatoma tissue was obtained during a middle ear operation, and the explant was cultured on six well-plates in a culture medium of Medium M-154 (Cascade Biologics Inc., USA) for one week. T-RA was then treated with 10M, 10M, 10M, 10M concentrations, respectively. The cholesteatoma explant cultures were observed daily, and topographic maps were constructed weekly to quantify the proliferation area. The explant culture area was estimated by Multiscan. RESULTS: In the absence of t-RA, the cholesteatoma explant culture area reached 401.5mm in four weeks. But with the administration of t-RA, the cultured area decreased proportionally to t-RA concentrations which reduced to 224.0 mm, 94.4 mm respectively in four weeks with 10M, 10M concentration of t-RA (p<0.05). CONCLUSIONS: This investigation showed that t-RA has a significant inhibitory effect on cholesteatoma proliferation. These results suggest that retionoids may have a role in controlling cholesteatoma disease.
