The purpose of this study was to understand the mechanism of cardiovascular disease (CVD) caused by exposure to hazardous chemicals. We investigated changes in the symptoms of metabolic syndrome, which is strongly related to CVD, and in levels of other CVD risk factors, with a special emphasis on the roles of catecholamines and oxidative stress. The results revealed that neither body mass index (BMI) nor waist and hip circumferences were associated with exposure to hazardous chemicals. Among metabolic syndrome criteria, only HDL-cholesterol level increased on exposure to hazardous chemicals. Levels of epinephrine (EP) and norepinephrine (NEP) were not influenced by exposure to hazardous chemicals; however, the total antioxidative capacity (TAC) reduced because of increased oxidative stress. Both hazardous chemical exposure level and metabolite excretion were related to EP, NEP, and the oxidative stress index (OSI). Logistic regression analysis with these factors as independent variables and metabolic syndrome criteria as dependent variables revealed that EP was associated with blood pressure, and NEP with metabolic syndrome in the chemical-exposed group. In conclusion, the results suggest that reactive oxygen species generated and oxidative stress due to exposure to hazardous chemicals act as mediators and cause changes in the physiological levels of EP and NEP to increase blood pressure. This ultimately leads to the development of CVD through increase in cholesterol, triglyceride, and blood glucose levels by lipid peroxidation.

Protein-tyrosine phosphatases (PTPs) constitute a family of receptor-like, and cytoplasmic enzymes, which catalyze the dephosphorylation of phosphotyrosine residues in a variety of receptors and signaling molecules. Together with protein tyrosine kinases (PTKs), PTPs are critically involved in regulating many cellular signaling processes. In this study, diverse compounds were screened for PTP inhibition and selectively screened for inhibitors with the end product inhibition properties. Among phosphate analogues and their derivatives for PTP inhibition, Keggin compounds phosphomolybdate (PM) and phosphotungstate (PT) strongly inhibited both PTP-1B and SHP-1, with K(i) values of 0.06-1.2 micromM in the presence of EDTA. Unlike the vanadium compounds, inhibition potencies of PM and PT were not significantly affected by EDTA. PM and PT were potent, competitive inhibitors for PTPs, but relatively poor inhibitors of Ser/Thr phosphatase. Interestingly, PM and PT did not inhibit alkaline phosphatase at all. The crystal structure of PTP-1B in complex with PM, at 2.0 A resolution, reveals that MoO(3), derived from PM by hydrolysis, binds at the active site. The molybdenium atom of the inhibitor is coordinated with six ligands: three oxo-ligands, two apical water molecules and a S atom of the catalytic cysteine residue. In support of the crystallographic finding, we observed that molybdenium oxides (MoO(3), MoO(2), and MoO(2)Cl(2)) inhibited PTP-1B with IC(50) in the range 5-15 micromM.

PURPOSE: The Mulliken's method is a one of the very excellent technique to correction of the unilateral cleft lip. It could decrease the need of additional operation and second operation by the early simultaneous correction of unilateral cleft lip and nasal deformity, at a time. Numerous procedures were advocated for the correction of nasal deformity, but with general dissatisfaction of the results, it became obvious that no one procedure is the ideal one. The authors have been operating on unilateral cleft lip by Mulliken's method and long term follow-up of postoperative result was evaluated. METHODS: The authors have done long term follow-up of results in the 75 cases unilateral cleft lip patient, during 1-7 years. That was repaired by simultaneous correction of cleft lip and nasal deformity by Mulliken's method at the period from June 1997 to December 2007. The patients were unilateral complete cleft lip 39 cases, unilateral incomplete cleft lip 36 cases. In the severe complete cleft lip cases, lip adhesion operation was done before definite operation. The mean age of unilateral cleft lip operation was 3.2 months. Five anthropometric parameters, which were upper lip, cutaneous lip and vermilion mucosa height, nasal tip protrusion, columella length were measured by Sliding Vernier Caliper. The anthropometric analysis was performed preoperatively, and the results were com pared with those of age- matched, normal children postoperatively in 6 months, 3, 5 and 7 years. T-tests were used to analyze the differences between the measurements. RESULTS: Long-term postoperative results were evaluated by anthropometrically. Most patients showed adequate growth of upper lip height, vermilion mucosa height and columella length. But nasal tip protrusion was relatively short compare to the normal value. Incomplete cleft lip group was nearly normal growth results than complete cleft lip group. CONCLUSION: In conclusion, we could make harmonious Cupid's bow, natural philtrum and lip, appropriate nasal shape by Mulliken's method. But nasal tip protrusion was under the normal values on complete and incomplete group. And incomplete group showed more good results than complete group. We have experienced repair of cleft lip by Mulliken's method with 75 cases of unilateral cleft lip patients and conclude that it is a very useful method.

We report two patients of generalized nonconvulsive status epilepticus (GNSE) accompanied by end-stage renal disease. Both patients were presented with impaired responsiveness and behavioral abnormalities. Continuous generalized epileptiform discharges were noted on EEG. GNSEs of our patients were responsive to benzodiazepines clinically and electroencephalographically. And they were controlled by short-term antiepileptic treatment and improvement of uremic condition. (J Korean Neurol Assoc 19(5):533~536, 2001)

PURPOSE: Human adipose tissue-derived mesenchymal stem cells(hATSCs) can be differentiated into multiple mesenchymal lineages, including bone, cartilage, and muscle. And growth hormone play important roles in the normal growth and development of the CNS. In this study, we explored whether the transplanted hATSCs and growth hormones could improve functional recoveries from rats with contusive spinal cord injury. METHODS: We divided 30 female rats, which were subjected to a weight driven implant spinal cord injury, into 3 groups with 10 rats each; Group A as a control group, group B with hATSCs transplantation on injured region, and group C with hATSCs transplantation and GH administration for 7 days. Then, we researched their neurologic functional recoveries before and 2, 4, and 8 weeks after transplantation using Basso-Beattie-Bresnahan (BBB) locomotor rating scale. And we checked Y- chromosome positive cells by FISH(Fluorescent in situ hybridization) to identify the survival of transplanted mesenchymal stem cells. RESULTS: After 4 weeks of transplantation, the group B and group C showed significant improvement of neurologic function on BBB locomotor rating scale in comparison with the group A(Group A: 13.1+/-0.58, Group B: 14.6+/-0.69, Group C: 14.9+/-0.56). Moreover, the group C displayed meaningful recovery of neurologic function after 8 weeks in comparison with group B (Group B: 15.7+/-0.63, Group C: 16.5+/-1.14). The group A, the control one, improved for 5 weeks after injury, and had no more recovery. On the other hand, Group B and C showed the improvement of neurologic function continuously for 9 weeks after injury. CONCLUSION: In this study, we found out that hATSCs transplantation have an effect on neurologic functional recovery of spinal cord injured rat and GH injection seems to bring the synergistic results on this good tendency.

BACKGROUND: Acute renal allograft rejection is not only risk factor of chronic rejection but is also a significant cause of graft loss and patient death. MMF has been shown to reduce the incidence and severity of acute rejection. METHODS: To compare the risk of acute rejection and side effects of MMF with azathioprine(AZA), a total of 108 patients, who received living transplants, were divided in two groups : MMF(n=48) and AZA group(n=60). Cyclosporin microemulsion(Neoral) and steroid were administered concomitantly to all patients. RESULTS: The MMF group was significantly lower rate of acute rejection compared with AZA group during the first 3 months after renal transplantation(14.6% vs 30.0%, p=0.005). 54.5% of patients in the MMF group and 44% in the AZA group were treated only with steroid pulsing for acue rejection. 45.5% in the MMF group, compared to 56% in the AZA group, required OKT3 or Atgam for treatment of severe acute rejection, the difference is not significant. Treatment failure occurred among 31.3% of the MMF group compared with 55% in the AZA group(p=0.013). Serum creatinine of 6 months after transplantation was significantly lower in the MMF group than in the others(1.31+/-.27 vs 1.50+/-.28 mg/dL, p=0.017). The incidence of opportunistic infection was similar in both groups. Gastrointestinal side effects were more common in the MMF group 14.6% than in the AZA group 3.3%(p=0.035), while leukopenia was more common in the AZA group 21.7% than in the MMF group 4.3%(p=0.017). CONCLUSION: MMF reduced the incidence of acute rejection without notable side effects. Long-term follow up will be needed to establish the protective effect of MMF against immunological attack.

We report a rare case of cryptococcal myositis with dissemination to lung in a 66-year-old diabetic woman who had no apparent risk factors for cryptococcal disease. She visited the hospital with a continuous pain in the right thigh and fever despite of treatment with antibiotics. She developed a localized lung infiltration. Crytococcus neoformans was isolated from the abscess of the right thigh and confirmed by molecular identification with DNA sequence analysis. Biopsy of the involved lung showed numerous budding yeasts consistent with Cryptocococcus species. The patient was successfully treated with surgical drainage and systemic antifungal agents.

PURPOSE: The aim of this study was to examine the effects of obesity on the physiological levels of adiponectin, leptin and components of metabolic syndrome (MS) in male workers, aged 30-40 years. METHODS: Body mass index (BMI) was measured with Anthropometric equipment. Blood pressure and serum parameters were measured with an automatic digital sphygmomanometer and autochemical analyzer, respectively. Adiponectin and leptin were analysed by ELISA kits and MS was defined based on the NCEP-ATP III. RESULTS: Body fat mass of waist and hip, systolic and diastolic blood pressure were significantly higher, as expected, in the BMI> 25kg/m2 in comparison with the BMI< or =25kg/m2. While fasting glucose, insulin, HOMA-IR and leptin in the BMI>25kg/m2 were also significantly higher compared with BMI< or =25kg/m2, HDL- cholesterol and adiponectin were significantly higher in BMI< or =25kg/m2. On multiple logistic regression analysis for the components of MS, exercise, adiponectin and leptin were an only independent factor for MS in non-obese male workers(BMI< or =25kg/m2) after adjustment for age, cigarette smoking and drinking habits. CONCLUSION: These results suggested that the obesity in men was associated with physiological levels of adiponectin and leptin contributing to feedback control of MS and that dysfunction and/or declination in feedback control system associated with changes in physiological levels of neurptrophics: adiponectin and leptin might ultimately induce MS.
