This study was undertaken to elucidate any quantitative abnormalities of Tlymphocyte subsets (helper/inducer T cell; T cell and suppressor/cytotoxic T cell: T cell) and IgE levels in the peripheraI blood in atopic dermatitis patients by using monoclonal antibodies and enzyme immunoassay, respectively. In addition we have tried to ascertain whether there are any correlations betveen such immuiiologic abnormalities and the severity of the disease. The results showed that there were significant decrease in the mean percentage of T Cells and increase in the mean value of T/T cell ratios in patients with atopic dermatitis. These changes seem to relate to the severity of the disease when evaluated as groups. A significant increase in the mean value of serum IgE was found in atopic dermatitis patients and the change was related to the severity of the disease. But increase of serum IgE level did not correlated closely with the T cell abnormalities in each patients.

A case of Kimuras disease was presented. It seemed that this is the first reported case in Korean literature. The patient was 26 years old male having painless slowly growing tumor-like swelling on his left cheek for 5 months. Mild leukocytosis and marked eosinophilia (27%) were noted in routine laboratory tests. Histopathologically numerous well developed lymphoid follicular structures composed of closely packed lymphocytes and histiocytes were seen in the deep dermis and subcutaneous fat tissue. Dense eosinophilic infiltrations in and around the follicles were peculiar picture. The literature was reviewed. Its relation to the similar descriptions in western literature under various diffe'rent headings was discussed;

Telomerase is an RNA-dependent DNA polymerase that synthesizes TTAGGG telomeric DNA onto chromosomal ends to compensate for sequence loss during replication. It has been detected in a variety of human malignancies, suggesting that such activity may play a role in the tumorigenic process. To determine whether telomerase is reactivated in malignant fibrous histiocytoma, 12 tissue samples with this tumor were analyzed for the telomerase activity by a radioactive PCR-based TRAP (telomeric repeat amplification protocol) assay. All of the tumors were further investigated for the expression of human telomerase RNA (hTR) by an in situ hybridization (ISH). Telomerase activity was detected in one (8.3%) sample. Expression of hTR was demonstrated in 7 (58.3%): one telomerase-positive and six telomerase-negatives. These data indicate that the reactivation of telomerase is an uncommon event and not an important factor involved in tumorigenesis in malignant fibrous histiocytoma. It is noteworthy that 50% of the patients with grade 2 tumors expressed hTR, suggesting that telomerase RNA may be useful as a marker for identifying tumor aggressiveness earlier than the conventional histopathologic grading scale.

PURPOSE: It is well known that linear growth in diabetic children is closely related to metabolic control and age of onset. Some studies showed growth retardation in diabetic children regardless of the degree of metabolic control, whereas others reported no growth impairment. Until now, no study has been done comparing linear growth between type 1 and type 2 diabetic children. Therefore, we compared the growth and weight status between type 1 and type 2 diabetic children. METHODS: 145 children with type 1 DM and 27 patients with type 2 DM were studied. Their growth status in height standard deviation score(HTSDS), obesity according to standard weight for height and body mass index(BMI), and HbA1c level at onset, 6 months, 1 year, 3 years and 5 years after treatment were compared. RESULTS: There was no distinct correlation in HTSDS in type 1 and type 2 DM, but in type 2 DM obesity according to standard weight for height and BMI was higher than in type 1 DM. deltaHTSDS 5 years after treatment of diabetic children with poor glycemic control were significantly decreased(P<0.05), but there was no significant correlation between HbA1c and obesity according to standard weight for height and BMI. CONCLUSION: There is no significant correlation between the type of diabetes and growth status, but the poor glycemic controled group showed a significant decrease in deltaHTSDS. These data suggest that the growth of diabetic children could be impaired in the case of poor glycemic control and long duration of diabetes.

For measurement of the degree of osteoporosis, various methods have been used. The Saville's index of the lumbar spine is very simple method. With the object of studying the reliability and clinical usefulness of Saville's index, authors compared the Saville's index with anteroposterior(A.P.) and lateral Dual x-ray absorptiometry, and the Singh's index with the anteroposterior D.X.A. We took the D.X.A. and simple lumbar spine lateral view in 124 patients in same time and also performed D.X.A. and both hips anteroposterior views in 112 patients, then analyzed the correlation between the A.P. and lateral D.X.A., Saville's index and D.X.A., Singh's index and D.X.A. The results were as follows. 1. The correlation coefficient of the A.P. and lateral D.X.A. was 0.46 and appeared the low degree of correlation. 2. The correlation coefficient of the A.P. and lateral D.X.A. compared with Saville's index were 0.68 and 0.83, respectively. Saville's index appeared the higher correlation in lateral D.X.A. than A.P. D.X.A. 3. The correlation coefficient of Singh's index and D.X.A. was 0.84, appeared nearly the same results of Saville's index with lateral D.X.A. 4. Intrapersonal differences were 36% in Saville's index, 28% in Singh's index. Saville's index appeared higher intrapersonal error than Singh's index. The lateral D.X.A. is more accurate and precise method than A.P. D.X.A. because lateral D.X.A. reduces the influence of soft tissue calcification and degenerative changes of spine. As Saville's index is a grading method based on lateral view of lumbar spine, we think that it should be compared with the lateral D.X.A. Regarding this results, authors suggest that Saville's index is not any accurate measurement of bone quantity, but has clinical usefulness for evaluation of osteroporosis.

Divergent placement of the femoral interference screw has been described as a major pitfall in single incision endoscopic reconstruction of the anterior cruciate ligament. This study reviews the radiographic results in 30 consecutive endoscopic single-incision ACL reconstructions using interference screw fixation to find a method to reduce the divergent femoral screw fixation. We measured the angles which were determined by a line through axis of femoral bone block and axis of interference screw in anteroposterior and lateral view of knee(APD/LD),through axis of femoral tunnel and axis of tibial tunnel in the full extension-anteroposterior view(AFT),through the longitudinal axis of distal femoral shaft and axis of femoral tunnel in the anteroposterior and lateral view(APFT/LFT). Average LD(4.96+/-62degrees) was significantly larger than average APD(1.303+/-13degrees) (P=0.008). Significant correlation was present between APD and APFT(g=-0.3882, P=0.034), between LD and LFT(gamma=0.6933, P=0.000) and other variables had no significant correlation. The femoral divergence in the anteroposterior plane occurred in the case with small angle between longitudinal axis of femoral shaft and that of femoral tunnel, and vice versa in lateral plane. During drilling of femoral tunnel, more than 90 flexion causes LFT to increase and the risk of femoral divergence increases. Therefore, in the anteroposterior plane, angle between femoral tunnel and longitudinal axis of femoral shaft shoud be made as large as possible and flexion of knee should not be more than 90 during drilling of femoral tunnel.

A simple, rapid and selective liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is developed and validated for quantification of venlafaxine in human plasma with simple liquid-liquid extraction step consisted of extraction with ether and dichloromethane for 10 min and mixing with 1 M sodium acetate in human plasma using fluoxetine as an internal standard (IS). The analyte are separated using an isocratic mobile phase consisted of acetonitrile and 5 mM ammonium formate (4/3, v/v) on a isocratic YMC hydrosphere C18 (2.0x50.0 mm, 3.0 microm) column and analyzed by MS/MS in the multiple reaction monitoring (MRM) mode using the transitions of respective [M+H](+) ions, m/z 278.2-->260.3 and m/z 310.1-->148.1 for quantification of venlafaxine and IS, respectively. The standard calibration curves showed good linearity within the range of 1.0-200.0 ng/mL (r2=0.9986, 1/chi2 weighting). The lower limit of quantification (LLOQ) was 1.0 ng/mL. The retention times of venlafaxine and IS were 0.6 min and 0.7 min that means the potential for the high-throughput potential of the proposed method. In addition, no significant metabolic compounds were found to interfere with the analysis. Acceptable precision and accuracy were obtained for the concentrations over the standard curve range. The validated method was successfully applied to bioequivalence study after 75-mg of venlafaxine sustained-release (SR) capsule in 24 healthy Korean subjects.
