Single dose(1.0 cc) of 20 % 2, 6-diiodo-4-nitrophenol solution was injected to 82 hookworm infected cases and 79% of them became egg-negative within 2-3 weeks after the injection. Mild to severe local pain were experienced for several minutes in all cases. Two cases complained of paralysis of the arms of the same side. The tablet of the same formula was given orally to 21 cases for 1-4 days. The 2-4 day course with 360 mg/day were enough to eliminate the parasite, and showed no systemic side effects.

Even the antituberculous drugs could cure the disease itself, it might not prevent progressive kyphosis and its sequelae. Therefore, radical curettage and anterior arthrodesis with autogenous strut bone graft has been used to prevent this deformity. From May 1982 to May 1989, twenty four cases of spinal tuberculosis treated with anterior arthrodesis were analysed about the progression of postoperative kyphosis. These cases were followed up for more than 1 year at least, and the following results were obtained; 1. Lumbar spine was most commonly involved. There was involvement of one disc space in 12 cases, only narrowing of disc space in 7 cases, and two disc spaces in 5 cases. 2. The degree of vertebral loss was under 1 in 15 cases, 0 (disc space narrowing only) in 7 cases, and over 1 in 2 cases. 3. Compared with immediate postoperative kyphotic angle, there was increase of kyphotic angle in 15 cases but most of them were under 10 degress. 4. Preoperative degree of vertebral loss of 15 incerased cases was 0.5 and that of 9 decreased of maintained cases was 0.2 in average. 5. Preoperative vertebral involvement of 15 increased cases was 1.3 and that of 9 decreased or maintained cases was 1.2 in average.

PURPOSE: To evaluate the in vivo corneal endothelial changes after intravitreal bevacizumab (Avastin(R); Genentech Inc., San Francisco, California, USA) injection. METHODS: A total of 30 eyes of 28 patients who received intravitreal bevacizumab injections were included in the present study. Before injection and one and three months after injection, specular microscopy was performed to analyze the corneal endothelial cell changes. In order to compare the differences in the changes of corneal endothelial cells, the eyes were divided into two groups, a single injection group and a multiple injection group. RESULTS: The mean endothelial cell count decreased from 2,497.4 +/- 427.8 at baseline to 2,421.2 +/- 430.5 at one month and to 2,362.7 +/- 366.2 at three months after the injection in all patients. However, the change in endothelial cell count was not statistically significant. In addition, the postoperative change in endothelial cell count was more prominent in the multiple injection group than in the single injection group, although the difference was again not significant. No significant changes in preoperative or postoperative coefficients of variation for cell area or hexagonalities were observed in either patient group or within each group. CONCLUSIONS: There was no significant change in corneal endothelial cells after intravitreal bevacizumab injection. In addition, there was no significant difference in the changes in corneal endothelial cells according to the number of bevacizumab injections.

PURPOSE: Thyroid tumor is one of the most common endocrine tumors, and yet little is known about its molecular process of development and progression. Cyclooxygenase (COX)-2, the inducible form of the COX enzyme for prostaglandin synthesis, is up-regulated in gastrointestinal cancers and is a key mediator of epithelial cell growth. Regular intake of aspirin or other nonsteroidal antiinflammatory drugs (NSAIDs) is associated with a decreased incidence of colorectal, esophageal, gastric, and lung cancer. We sought to determine the involvement of COX-2 in human thyroid cancer. METHODS: COX-2 protein was assayed in thyroid tissue of 64 which were inflammatory disease and benign tumor and malignant tumor with or without metastasis patients by using immunohistochemistry and Western Blot analysis. RESULTS: COX-2 protein was not expressed in normal thyroid tissue. But COX-2 protein was expressed strongly in inflammatory tissue. Expression of COX-2 was very high in both benign and malignant tumor. There is no difference in pathology and malignant potential or existence of metastasis. CONCLUSION: There was no correlation between clinicopathological characteristics of thyroid tumor and intensity of COX-2 protein expression. In addition, there was no difference of expression of COX-2 between inflammatory thyroid disease and thyroid tumor. This study indicates that COX-2 protein over expression may contribute to an early event of gastric cancer development, and it further suggests that selective inhibition of COX-2 may provide a chemopreventive effect against thyroid cancer.

PURPOSE: VEGF, a potent angiogenic factor, increases vascular permeability and induces the fluid accumulation in the peritoneal and pleural cavities. This study is designed to know whether the VEGF concentration are associated with the formation of cystic fluid of thyroid nodules and the results of treatment. METHODS: To know whether thyroid follicular cells produce VEGF, we measured the VEGF concentration in the conditioned medium after primary culture of the normal thyroid follicular cells (NT 1.0). Thirty seven patients, who had visited Ajou University Medical Center, were divided into two groups; group A (n=19) is patients whose cystic nodules disappeared completely with 1 or 2 times fine needle aspirations. In Group B (n=18), the cystic nodules recurred rapidly and required aspiration more than 3 times. Clinical records of patients were analyzed and compared with TSH and VEGF levels in cystic fluids. RESULTS: The VEGF concentration in basal conditioned medium were 8.2±1.2 ng/ml in NT 1.0 and 8.2±0.6 ng/ml in thyroid cancer cell line (FTC-133). NT 1.0 was not affected by TSH stimulation. Mean concentration of TSH of all cystic fluids was 4.36µIU/ml (0.13~21.7) and there was no difference between 2 groups. Mean concentration of VEGF of all cystic fluids was 140.7 ng/ml (11.1~688.8). The VEGF concentration (287.9±289.6 ng/ml) in group B was significantly higher than that (104.2±97.1 ng/ml) in group A (P<0.05). CONCLUSION: This study suggests that thyroid follicular cells produce and secrete VEGF, and VEGF is related with the accumulation of cystic fluid in degenerative cysts of thyroid. Cysts with high VEGF concentration promote rapid reaccumulation of the cystic fluid and possibly necessitate operation in selected patients.

OBJECTIVES: The purpose of this study is to evaluate the problem behaviors of adolescents and to discriminate between parenting behaviors of problem behavior groups and those of non-problem behavior group. METHODS: The subjects of this study were 792 high school students in Seoul. We administered 'Parenting Behavior Inventory' and Korean version of Youth Self-Report(K-YSR) to the subjects in order to evaluate the parenting behaviors perceived by adolescents and the problem behaviors of adolescents. We analyzed the relationship between parenting behaviors and problem behaviors. We classified the subjects into problem behavior groups(internalizing group, externalizing group, internalizing-externalizing group) and a non-problem behavior(normal) group. We studied the differences of parenting behaviors among the groups. RESULTS: The results are as follows. 1) There were significant negative correlations between the positive parenting behaviors such as affection, reasoning, and monitoring and the problem behaviors of adolescents. By contrast, there were significant positive correlations between the negative parenting behaviors such as physical abuse, intrusiveness, over-expectation, neglect, and inconsistency and the problem behaviors of adolescents. 2) Adolescents of the internalizing group perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Meanwhile, they perceived significantly less affection than normal adolescents. Adolescents of the externalizing group also perceived significantly more parental abuse, intrusiveness, over-expectation, neglect, and inconsistency than those of normal group. Also, they perceived significantly less monitoring than normal adolescents. 3) Adolescents of the internalizing-externalizing group perceived significantly more intrusiveness from both parents than those of either the internalizing or the externalizing groups. Adolescents of the internalizing-externalizing group perceived significantly less affection and more neglect from their mothers than those of the internalizing or the externalizing groups. In addition, adolescents of the internalizing-externalizing group perceived significantly more physical abuse from their fathers than those of the internalizing or the externalizing groups. CONCLUSION: Parenting behaviors such as abuse, intrusiveness, over-expectation, neglect, and inconsistency are associated with both internalizing and externalizing problems. In contrast, our results suggest that parenting behaviors such as affection, monitoring, and reasoning might decrease the various problem behaviors of adolescents.

PURPOSE: The increased prevalence of childhood asthma in Korea from 3.4% in 1964 to 15% in 1995 might be very important for morbidity and mortality in children. Recognition of this led to consider the necessity of new management strategies emphasizing patient education. We developed the educational program including asthma-specific play game called 'Malgunsum asthma game' to improve the child's interest and evaluated its educational effect. METHOD: Twenty asthmatic children between the age seven to fifteen were attended Malgunsum Asthma Camp. The Children were randomly assigned to 5 groups, and each player had to move the horse by answering the questions on the card. The first one who reaches the goal wins the game. RESULTS: All the children well followed the play rule and were interested to the game. CONCLUSION: This educational game model will achieve better control of asthma by leading the patients to understand the nature of asthma, how to identify and control the aggravating factors, how to recognize symptoms and appropriate steps for asthma, and the importance of daily maintenance therapy with anti-inflammatory medications.

Chronic hepatitis is one of the leading cause of hospitalization and death in kidney transplanted patient. Korea is one of the endemic area of chronic hepatitis B. The impact of hepatitis B virus (HBV) infection on the clinical course of renal transplant recipient has been controversial. We describe five Hepatitis B surface antigen (HBsAg) positive renal transplant recipients who transplanted at the KyungHee University Medical Center during the period of January 1992 to July 2000. All these patients have no clinical sign or symptom of chronic hepatitis at the time of transplantation. Mean follow up period was 70 month (range 7-57). Three of 5 patients developed liver cirrhosis with complications during follow-up period. One patient died of fulminant hepatitis due to reactivation of HBV. The remaining one patient is free of disease till now. Four of 5 patients maintained the function of transplanted kidney and only one patient restarted hemodialysis.

OBJECTIVES: Thalamic structural changes were implicated in the pathophysiology of schizophrenia by some studies. So, we investigated the differences in thalamic volumes between previously untreated patients with first-episode schizophrenia and controls. METHODS: Thalamic volumes of 24 subjects with schizophrenia and 24 controls were measured from their T1-weighted coronal magnetic resonance images using manual tracing. The thalamus was further segmented into regions that roughly reflected individual thalamic nuclei. RESULTS: Comparing to the controls, significantly smaller volumes were found in the left posterior subdivision of thalamus in patient group. Tendency of volume differences were also seen in right posterior subdivision of thalamus in patient group. These regions primarily comprised the pulvinar, a thalamic nucleus thought to be an important component of aberrant circuitry in schizophrenia. CONCLUSION: Our findings suggest the possibility of a volumetric alteration of the thalamus in patients with first-episode schizophrenia.
