OBJECT: Patients with facial asymmetry accompanying mandibular prognathism have various causes and clinical features. So, it is difficult to find a satisfactory treatment method functionally and esthetically. Every traditional classification and interpretation to find etiopathogenesis and/or to establish ideal surgical modality has many limitations because it can't be applied simply to various conditions of patients with facial asymmetry accompanying mandibular prognathism. Therefore, we employ a new classification to interpret more details of the morphologic change of mandible and the spatial change of mandible and maxilla. MATERIALS AND METHODS: Using panoramic X-ray films, PA cephalograms and submentovertex films of 126 patients diagnosed with facial asymmetry accompanying mandibular prognathism as resources, the following results were gathered after analyzing each characteristics through distributing the patterns according to the morphological mandibular asymmetry and mandibular and maxillary spatial asymmetry. RESULTS: Almost frequency of morphological mandibular asymmetry was shown. In case of condyle-ramus elongation and body elongation group, it's frequency was the highest. Higher frequency of compensating vertical growth was shown on the side of over growing maxilla in case of vertical length difference between left and right condyle-ramus. On the other hand, higher frequency of no compensating vertical growth difference between left and right side was shown in case of no vertical length difference in condyleramus. Spatial mandibular asymmetry generally occurred when there was no morphological mandibular asymmetry. Correlation between condyle length difference and condyle-ramus length difference between left and right side was very high, but correlation between condyle length difference and body length difference, and correlation between condyle length difference and body vertical length difference was low. CONCLUSION: In case of patients with facial asymmetry accompanying mandibular prognathism, it is suggested that various pattern of facial asymmetry is occurred by the independent growth of each unit rather than dependent growth of other unit by major growth unit abnormality. Due to the untypical pattern and the various asymmetry occurring according to the changes of each mandibular growth unit, it is considered that an appropriate surgical method should be searched based on the accurate recognition of the each pattern for patients with facial asymmetry accompanying mandibular prognathism.

PURPOSE: Interleukin-6 (IL-6) can stimulate a variety of tumors including prostatic carcinoma. Research has recently shown that IL-6 may act to stimulate the progression of prostatic cancer. IL-6 is elevated in the sera of patients with metastatic prostatic cancer and it has been shown to be a candidate marker of disease activity. To date, little work has been performed to characterize the nature of granulocyte macrophage colony-stimulating factor (GM-CSF) and the expression of IL-6. The aim of this study is to evaluate the effects of GM-CSF on the expression of IL-6 in PC-3 cells. MATERIALS AND METHODS: The bone-derived PC-3 cell line was used in this study. Reverse transcription polymerase chain reaction (RT-PCR) was performed to detect the GM-CSF and also the IL-6 mRNA expression. The IL-6 protein was measured by enzyme-linked immunosorbent assay (ELISA) after treatments with the hGM-CSF. RESULTS: hGM-CSF was expressed in the PC-3 cell line. Our data indicated that the IL-6 mRNA expression was not increased at 4, 8 and 12 hours by the hGM-CSF in comparison to the control group, but it was slightly increased at 24 and 48 hours. The expression of IL-6 protein was increased at 4, 8, 12, 24 and 48 hours after hGM-CSF treatment, in comparison with the control group. CONCLUSIONS: The IL-6 mRNA expression was slightly increased by hGM-CSF at 24 and 48 hours in comparison to the control group. Yet the IL-6 protein expression increased before the IL-6 mRNA expression. Therefore, hGM-CSF may modulate the post-transcription pathway of the IL-6 expression in prostate carcinoma cells. Our data suggest that GM-CSF may have a possible IL-6 mediated pathophysiologic role in prostate cancer.

OBJECTIVES: The purpose of present study is to investigate the influence of a spinal gamma-aminobutyric acid B (GABAB) receptor on a central regulation of blood pressure(BP) and heart rate(HR), and to define its mechanism in the spinal cord. METHODS: In urethane-anesthetized, d-tubocurarine- paralyzed and artificially ventilated male Sprague-Dawley rats, intrathecal administration of drugs were carried out using injecton cannula(33-gauge stainless steel) through the guide cannula(PE 10) which was inserted intrathecally at lower thoracic level through the puncture of a atlantooccipital membrane. RESULTS: Intrathecal injection of an GABAB receptor agonist baclofen(30, 60, 100 nmol) decreased both blood pressure and heart rate dose-dependently. Pretreatment with 8-bromo-cAMP(50 nmol), a cAMP analog or glipizide(50 nmol), a ATP-sensitive K+ channel blocker attenuated the depressor and bradycardic effects of baclofen (100 nmol) but not with 8-bromo-cGMP(50 nmol) a cGMP analog. CONCLUSIONS: The GABAB receptor in the spinal cord plays an inhibitory role in central cardiovascular regulation and that this depressor and bradycardic actions are mediated by the decrease of cAMP via the inhibition of adenylate cyclase and the opening of K+ channel.

BACKGROUND: The aim of this study was to investigate the prevalence, clinical and laboratory findings of hereditary hemolytic anemia (HHA) in Korea from 1997 to 2006 and to develop the appropriate diagnostic approach for HHA. METHODS: By the use of questionnaires, information on the clinical and laboratory findings ofHHA diagnosed from 1997 to 2006 in Korea was collected and analyzed retrospectively. A total of 431 cases were enrolled in this study from 46 departments of 35 hospitals. RESULTS: The overall frequency of HHA did not change through the 10-year period for pediatrics but did show an increasing tendency for internal medicine. The overall male to female sex ratio did not show sex predominance (1.17:1), but a significant male predominance with a ratio of 1.49:1 was seen for pediatrics while a significant female predominance with a ratio of 1:1.97 was seen forinternal medicine. Of the total cases, 74.2% (282/431) were diagnosed before the age of 15 years. The etiologies of HHA were classified as red cell membrane defects, hemoglobinopathies, red cell enzyme deficiencies and unknown causes. There were 382 cases (88.6%) of red cell membrane defects with 376 cases (87.2%) of hereditary spherocytosis and 6 cases (1.4%) of hereditary elliptocytosis, 20 cases (4.6%) of hemoglobinopathies with 18 cases (4.2%) of beta-thalassemia, a case (0.2%) of alpha-thalassemia and a case (0.2%) of Hemoglobin Madrid, 7 cases (1.6%) of red cell enzyme deficiencies with 5 cases (1.2%) of glucose-6- phosphate dehydrogenase (G-6-PD) deficiency, a case (0.2%) of pyruvate kinase (PK) deficiency and a case (0.2%) of enolase deficiency, and 22 cases (5.1%) of unknown causes. The most common chief complaint in pediatric patients was pallor and that in adult patients was jaundice. In the red cell membrane defect group of patients, the level of hemoglobin was significantly higher than in adult patients. The mean corpuscular volume, mean corpuscular hemoglobin, corrected reticulocyte count, total and indirect bilirubin level and lactate dehydrogenase levels in the hemoglobinopathy group of patients were significantly lower than the values in the red cell membrane defect group of patients. The mean concentration of G-6-PD was 0.8+/-0.7U/1012RBC in the G-6-PD deficient patients, PK was 1.7U/1010 RBC in the PK deficient patient, and the level of enolase was 0.04U/g of Hb in the enolase deficient patient. CONCLUSION: The most prevalent cause of HHA in Korea during 1997 to 2006 was hereditary spherocytosis, but HHA by other causes such as hemoglobinopathy and red cell enzyme deficiency gradually increased with the development of molecular diagnostic methods and increasing general interest. However, the etiologies of HHA need to be pursued further in 5.1% of the patients. An systematic standard diagnostic approach is needed in a nationwide prospective study for correct diagnoses and appropriate management of HHA.
