BACKGROUND: Chlamydia pneumoniae, a new species of the obligate intracellular Chlamydia, has been recognized as a significant pathogen that causes infection of the human respiratory tract and has recently been associated with coronary atherosclerosis. Diagnosis of infections with C. pneumoniae is problematic, because the syndrome usually presents few distinguishing features and culture of the organism is far more difficult than other Chlamydia species. To further improve the cell culture isolation and passage of C. pneumoniae organisms. we have studied several chemical and physical factors that might affect their viability and growth. METHODS: C. pneumoniae strain (TW-183) was obtained from the Centers for Disease Control, Atlanta. Ga. First we compared McCoy HeLa-229, and HEp-2 cells in the search for a more efficient and practical cell culture system. The growth rate of C. pneumoniae was assessed by the effects of diethylaminoethyl-dextrin, by the adequate centrifugation force and time, by the growth promoting effect of cycloheximide, and by the optimal incubation time. All of the results were evaluated by the indirect immunofluorescent stain using the genus-specific monoclonal antibody(HYMo 1-1) to Chlamydia. RESULTS: The HEp-2 cell was the most efficient for culturing C. pneumoniae and the inclusion bodies in monolayer were increased with DEAE-dextran pretreatment at 30microgram/ml. Also application of a centrifugal force of 1.500 xg for at least 15 minute during inoculation enhanced the growth of C. pneumoniae. The best concentration of cycloheximide in the culture medium for host cell cytostasis was 1microgram/ml. The yields of organisms were greater when the cultures were harvested at 48 hours. CONCLUSIONS: We suggest that this system may make it more practical for laboratories to culture for C. pneumoniae.

A 43 year-old Korean male has had multiple, grouped, asymptomatic, yellowish brown flat papules and nodules on the knees, elbows, buttocks, palms and soles for 3 years. Small yeIlowish, discrete papules first appeared on the right palm and left elbow, and gradually increased in size and number and spread to knees, buttocks and soIes. Physical examination revealed normal except for the skin lesions and no familial occurrence was noted. Gross finding of the serum was turbid, more or less creamy and paper electrophoresis revealed marked increase of prebetalipoprotein, increase of betalipoprotein and alphalipoprotein and absence of chylomicron, suggesting type III or type IV hyperlipoproteinemia. Serem choleterol was 200mg% and fasting blood sugar was 115.0mg%. with normal glucose tolerance test. Histopathology showed many aggregates of foam cells on H-E stain and many lipid droplets in the dermis on Sudan red stain. Based on the clinical and histopathological findings and lipoprotein analysis by the paper electrophoresis, the patient was diagnosed as type IV hyperlipoproteinemia with xanthoma tuberosum.

We present two cases of acute febrile neutrophilic dermatosis developed in women aged 56 and 52. One of the two patients deveIoped the lesions during longterm antituberculosis chemotherapy for her advanced pulmonary tuberculosis, The other case developed the lesions, initially at the site of acupuncture done for relief of her arthralgia, followed by the involvement of the other sites. The etiology of acute febrile neutrophilic dermatosis is not clear, however, hypersensitivity and association with systemic diseases such as upper respiratory infection, malignancies, ulcerative colitis and pyoderma gangrenosum are postulated.

The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n=16, 100%), hyperattenuation of MCA (n=3), obscuration of lentiform nucleus (n=6), loss of insular ribbon (n=6) and subtle low density in hemisphere (n=5). The most frequent findings was effacement of cortical sulci in our study, and it was though to be the most important sign of early acute cerebral infarction.

The cryopathic hemolytic anemia is an autoimmune hemolytic anemia induced by cold antibody. Authors report a case of cryopathic hemolytic anemia confirmed by immunohematologic examination. A 22-year-old man was admitted at Kyung Hee Medical Center in March, 1994, with a past history of Kleinerfelter's syndrome and complained jaundice as well as dizziness. Direct antiglobulin test using polyvalent and anti-C3d monovalent antisera was positive, but was negative against anti-IgG, anti-IgA, and anti-IgM monovalent antisera. Cold agglutinin titer was as high as 1:1024 at 4 degrees C and anti-I specificity was confirmed by using cord bloods. The patient was not improved despite transfusion of washed red cells and administration of prednisolone, and on 16th day of hospitalization he manifested sudden episode of headache and loss of conscioussness, soon followed by death.

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.
