Intensive insulin therapy effectively delays the onset and slows the progression of nephropathy in patients with IDDM. TGF- 0 has recently been implicated in the pathogenesis of diabetic nephropathy. We evaluated the effects of different level of glucose control with insulin therapy on the progression of diabetic nephropathy in age-matched control rats(C) and 3 groups of streptozotocininduced diabetic rats', high blood glucose diabetic rats without insulin therapy(HG), rnoderate glucose diabetic rats with insulin therapy(MG), and normal glucose diabetic rats with intensive insulin treatment (NG). Glomerular volume(VG) was measured using Image-Pro morphometric software, glomerular TGF- Bl mRNA expression by in situ hybridization, and glomerular expression of TGF-8 and type IV collagen proteins by immunohistochemical staining. VG was significantly higher in HG than in other groups in 12 weeks. Kidney weight(KW) was the highest while the body weight the lowest in HG of all groups in 12 weeks. Daily urine albumin excretion (UAE) increased with time in all groups but was significantly larger in HG than in all other groups in 12 weeks. MG also had significantly larger UAE than C in 12 weeks. There was no difference in VG, KW, and UAE between NG and C. Glomerular TGF-Bl mRNA expression was significantly higher in HG than in all the rest of the groups in 4 and 12 weeks. Glomerular expression of TGF-B and type IV collagen proteins was proportional to the levels of blood glucose, being the highest in HG in 12 weeks. There was little or no expression of TGF-0 1 mRNA and protein or type IV collagen protein in NG. Thus these results support the view that high blood glucose is the prerequisite for glomerular injury in diabetes mellitus and that the glomerular injury in diabetes mellitus is mediated, in part, by TGF-01 and suppressed by glucose control.

PURPOSE: This study was designed to determine whether transabdominal ultrasound can detect different hepatic stiffness between patients with cirrhosis and control subjects. MATERIALS AND METHODS: Sevent-three patients (Child-Pugh class A stage) with liver cirrhosis and 57 control subjects were included in this study. All patients were subdivided arbitrarily into two groups: early cirrhosis (n = 53) and overt cirrhosis (n = 20). Two sagittal images of the left lobe of the liver were obtained in the left hepatic vein level during the resting state and at full inspiration while pushing their belly out, by abdominal US (i.e., resting and stress image). The length between the inferior hepatic angle and the midpoint of the liver dome was measured in all images for the evaluation of liver distortion. The elongation was calculated by a formula: (L2-L1/L1) x 100(%); where L1 and L2 are the length of the liver for both the resting and stress image. The calculated elongated length (L2-L1, EL) and elongation rate were compared between cirrhotic patients and control subjects. RESULTS: For the control subjects, early cirrhosis, and overt cirrhosis groups, the mean ELs (elongation rate) were 2.34+/-0.98 cm (30.2+/-13.2%), 1.18+/-0.73 cm (14.9+/-9.5%) and 0.53+/-0.54 cm (6.3+/-6.6%), respectively. This difference among the three groups was statistically significant (p < 0.05). A possible best cut-off value of liver elongation rate is 17% for the prediction of cirrhosis (sensitivity: 90%, specificity: 75.3%). CONCLUSION: The liver of patients with liver cirrhosis is stiffer than that of control subjects. Calculation of the elongation rate in the left lobe of the liver during a respiratory maneuver may be used as an ancillary method of US for the evaluation of liver cirrhosis.

BACKGROUND: High glucose upregulates MCP-1 expression in rat glomerular mesangial cells and in human peritoneal mesothelial cells. However, the role of high glucose-induced MCP-1 on the development and progression of diabetic renal injury and peritoneal injury during peritoneal dialysis(PD) using high glucose PD solutions are not clear. Since MCP-1 was shown to upregulate transforming growth factor-beta1(TGF-beta1) and collagen expression in lung fibroblasts, the present study investigated the effects of MCP-1 on fibronectin secretion by mouse mesangial cells(MMC), human peritoneal mesothelial cells (HPMC), and human peritoneal fibroblasts(HPFB). METHODS: Synchronized cells were stimulated by different concentrations of MCP-1(0.1-100 ng/mL) or TGF-beta1(0.1-10 ng/mL) for 48 hours. Fibronectin protein secreted into the media was analyzed by Western blot analysis. RESULTS: MCP-1 up to 100 ng/mL did not affect fibronectin secretion by MMC. TGF-beta1 10 ng/mL, however, increased fibronectin secretion by MMC 2.8 fold that of control. MCP-1 up to 100 ng/mL did not affect fibronectin secretion by HPMC. But, TGF-beta1 0.1 ng/mL increased fibronectin secretion by HPMC 1.8 fold compared to control. On the other hand, MCP-1 increased fibronectin secretion by HPFB in a dose-dependent manner. MCP-1 at 1-10 ng/mL significantly increased fibronectin when compared to M199 control. 100 ng/mL MCP-1 further increased fibronectin secretion by HPFB compared to 0.1-10 ng/mL MCP-1. CONCLUSION: These results suggest a possible role for MCP-1 in the development and progression of peritoneal fibrosis and support the view that in addition to recruiting inflammatory cells MCP-1 may play a role in tissue fibrosis in other organs.

OBJECTIVE: The purpose of this retrospective study was to report the outcome of the endovascular treatment of eight patients with eight saccular posterior inferior cerebellar artery (PICA) aneurysms. MATERIALS AND METHODS: Over the last seven years (1999-2006), eight consecutive patients with saccular PICA aneurysms were treated by endovascular methods. Five of the aneurysms were presented with subarachnoid hemorrhaging, whereas three were discovered incidentally. Four of the aneurysms (3 ruptured and 1 incidental) were treated by intrasaccular coiling, whereas the remaining four (1 ruptured and 3 incidental) were treated by vertebral artery (VA) occlusion. RESULTS: Of the four aneurysms treated by intrasaccular coiling, three were completely packed with coils and one was partially packed. In three of four patients who underwent vertebral artery occlusions, follow-up digital subtraction angiographies demonstrated thrombosed aneurysms and PICA. No procedure-related morbidity occurred and no re-bleed was encountered during a follow-up examination (mean; 31 months). CONCLUSION: As a result of this study, we found that the endovascular management of saccular PICA aneurysms should be considered as safe and effective.

To estimate the incidence of uterine cervix cancer among Korean women, we have conducted a study using the claim data on the beneficiaries of Korea Medical Insurance Corporation(KMIC). All medical records of the potential cases with diagnosis of ICD-9 180, 181, 182, 199, 219, 233 in the claims sent by medical care institutions in the whole country to the KMIC from January 1988 to December 1989, were abstracted and Gynecology specialist reviewed the records to identify the new cases of uterine cervix cancer among the potential cases during the corresponding period. Using these data, the incidence of uterine cervix cancer among Korean women was estimated as of July 1, 1988 to June 30, 1989. The crude rate was estimated to be 17.34(95% CI: 16.76~17.92) per 100,000 and the cumulative rates for the ages 0~64 and 0~74 were 1.7% and 2.2%, respectively. The age-adjusted rate for the world population was 19.93 per 100,000 which was higher than those of other Asian countries including China and Japan in 1983~1987. The truncated rate for ages 35~64 was 52.05 per 100,000 which was one of the highest in the world. With increasing age, the incidence rate increased to 78.11 per 100,000 in women aged 55~59 years, then it decreased in the older groups. This finding suggests that detecting rate of uterine cervix cancer may decrease in women aged 60 years or older due to detecting rate of uterine cervix cancer may decrease in women aged 60 years or older due to inadequate medical care seeking behavior. In the geographical area, the SIR of Jeju province was significantly low but it might be due to statistical unstability by small case numbers.

This study was done for identifying the factors which affect psychologic symptoms of low back(LBP) patients. The study subjects were 43 work-related low back pain patients, 28 work-related non-low back pain patients and 47 general low back injury patients. The study material is SCL 90-R for checking psychologic symptoms and questionnaire for obtaining general information about the subjects. The data were analyzed by model of analysis of covariance adjusted by several variables such as gender, age, education and marital status and then compared the least square means of symptom score between groups. To identify the factors that affect psychologic symptom, duration of suspension, return to work and interaction factor of these two variables were analyzed by multivariate model and we calculated partial correlation coefficient of these variables. As a result, work-related LBP patients showed higher score of symptoms in somatization, depression and psychosis than work-related non-LBP and non-work-related LBP. Duration of suspension and return to work were significant explanatory variables for psychologic symptom score of work-related LBP. Then, we may conclude that the treatment and rehabilitation programe for work-related LBP should cover the strategy of early return to work.

A retrospective analysis of 60 patients with traumatic subdural hygroma who had been managed and followed up at least 6 months, was done in relation to time of development and associated intracranial lesion, initial Glasgow Coma Scale(GCS), sequeritial changes of subdural hygroma, and Glasgow Outcome Scale(GOS). The incidence of traumatic subdural hygroma was 8.4%, 131 cases among 1,563 head-injured cases. And most of them was subacute from(55%, 33 cases among 60 cases), complex subdural hygroma was 65%(39 cases among 60 cases). The conversion rate of traumatic subdural hygroma into chronic subdural hematoma was 15%(9 cases among 60 cases). There was no statistically significant relation between initial GCS score and time of development and also intial GCS score and development of complex subdural hygroma and time of development and GOS of 6 months follow-up(P>0.05). There noted only highly significant relation between initial GCS score and GOS of 6 months follow-up(P<0.001).
