PURPOSE: TGF-beta is a key regulator of epithelial-mesenchymal transition. Among the TGF-beta responses, cell migration is closely associated with the expression of matrix metalloproteinases (MMPs). Therefore, we determined which MMPs are regulated by TGF-beta and examined the TGF-beta signaling involved in this event, focusing on Src family tyrosine kinases (SFKs) METHODS: First we examined the expression of MMPs in rat lens explant culture treated with TGF-beta and LECs attached to the anterior capsules of patients with nuclear (N), anterior polar (AP) cataracts using RT-PCR and immunofluorescence staining. It was examined whether the expression of MMPs is regulated by SFKs. RESULTS: The study using RT-PCR and immunofluorescence staining showed the expression of MMP-2 and -14 in explants and the expression of MMP-14 LECs of AP cataracts. The expression of MMP-2 and -14 was blocked by PP2 in explants. Furthermore, the activated form of SFKs was observed in LECs of AP cataracts by immunofluorescence staining. CONCLUSIONS: We suggest a novel role of SFKs signaling in the expression of MMP-14 induced by TGF-beta.

Heterotopic pregnancy is named when an extrauterine (ectopic) pregnancy coexists with an intrauterine pregnancy simultaneously by many causes such as PID (pelvic inflammatory disease), endometriosis, IUD (intrauterine device), previous pelvic surgery and others. This is very rare in general population, with a range of occurrence estimated between 1:7963 and 1:30000. But recently the incidence has increased as the uses of ARTs (assisted reproductive technologies) including ovulation induction, IVF-ET (in-vitro fertilization and embryo transfer) and GIFT (gamete intrafallopian transfer) increase. Because this has high maternal morbidity, mortality and fetal loss, early diagnosis and proper management is very important. We report a case of heterotopic pregnancy following IVF-ET with a brief review.

Multiple satellite pyogenic granuloma developed on the left upper back of a 14-year-old boy after excision of a hemangioma-like lesion. He has had nevus flammeus on the left upper arm since birth with fine linear telangietasiae around the main lesions. Histopathology showed the capillary proliferation in the dermis, and transmission electron microscopy revealed multiple Weibel-Palade bodies, considered an early endothelial cell marker, in the cytoplasm of the endothelial cells. We believe this patient may have the propensity to develop different angiomatous lesions.

Backgound: The placement of stents in coronary arteries has been shown to reduce acute closure and restenosis in comparison to balloon angioplasty. However, clinical use of intracoronary stents is impeded by the subacute stent thrombosis and hemorrhagic complications associated with the anticoagulant regimen. It's known that the complete stent deployment with high pressure inflation and new antiplatelet agents are effective in reduction of subacute thrombosis and hemorrhage. So we evaluated initial results (success and complication rate) after high pressure-stent deployment with new anticoagulation protocol. METHODS: One hundred and ninety one patients with 201 lesions were treated with 231 stents of various types. The high pressure balloon inflation and antiplatelets agents were used in all cases. Final high pressure balloon inflation guided by IVUS were performed in 23 consecutive cases with incomplete stent deployment according to angiographic findings. RESULTS: 1) The indications of stenting (n=210) were De novo in 124 (59%), bailout procedure in 57 (27%), suboptimal result after PTCA in 19 (8%), and restenosis after PTCA in 14 (6%). The location of lesions were LAD in 101, RCA in 67, circumflex in 28, ramus intermedius in 3, and LMT artery in 2 lesions. Angiographic morphologic characteristics were type A in 2, type B in 158 (B1: 57, B2: 101), and type C in 22 lesions. 2) The angiographic and clinical success rate was 96% (192/201) and 92% (186/201) respectively. 3) In angiographic analysis, the baseline average reference vessel dirmeter was 3.33+/-0.35 mm. Baseline minimum lumen diameter (MLD) was 0.58+/-0.29 mm, with baseline percent diameter stenosis of 82.86+/-8.64%. The final stent diameter was 3.37+/-0.29 mm, with mean final percent stenosis of 0.63+/-8.25. The mean MLD after stenting was significantly increased (p<0.001). The mean MLD within stent increased 14%, from 2.91+/-0.39 mm at the nominal balloon inflation (inflation pressure=7 atm) to 3.37+/-0.29 mm at high pressure balloon inflation (inflation pressure <0A65B>12atm) (p<0.001). The length of lesions in GR I (cook), GR II, and Micro II stents were significantly longer than ones in PS, Cordis, Wiktor, Nir (p<0.001). 4) In intravascular ultrasound analysis, the mean lumen CSA at the tightest point within stent increased 11%, from 8.4+/-2.4 mm2 at the intial intravascular ultrasound to 9.4+/-2.1 mm2 at the final intravascular ultrasound (p<0.001). 5) The procedural and postprocedural complications were 2 acute closures associated with AMI and emergent CABG, 1 subacute closure which was revascularized by bail out stenting, 5 major hemorrhage requiring transfusion associated with 1 CVA and 2 metabolic acidosis induced by acute renal failure, and 5 death. CONCLUSION: The high pressure stent deployment procedure and new anticoagulation protocol associating tidopidine and aspirin without coumadin or prolonged heparin infusion allow us to obtain an acceptably low subacute thrombosis or bleeding complication rate. These results are encouraging and allow a wide use of coronary stenting.

PURPOSE: The aim of the present study was to investigate the effect of single dose imipramine on nocturnal urine output in patients with nocturnal enuresis. METHODS:A total of 6 monosymptomatic enuretic patients of more than 5 years of age were enrolled in this study. We measured nocturnal urine output, urine osrnolality, creatinine clearance, osmolal clearance, excretion rate of solutes, fractional excretion of sodium and potassium, and plasma vasopressin with and without a single oral dose of imipramine(lmg/kg of body weight) at 8 p.m. RESULTS: The administration of imipramine was followed by a significant decrease in noctumal urine output(P=0.02). Urine osmolality was not significantly increased(P>0.05), but osmolal clearance was significantly decreased during imipramine medication(P=0.03). Urinary excretion rate of sodium and potassium showed a statistically insignificant trend toward lower values during imipramine administration in nocturnal enuretics. Fractional urinary excretion of sodium and potassium was significantly decreased during imipramine medication(P<0.05). There was no significant difference in plasma vasopressin level and creatinine clearance in nocturnal enuretics after imipramine. CONCLUSION: Imipramine has a vasopressin independent antidiuretic effect in patients with nocturnal enuresis. The antidiuretic effect of imipramine can be attributed prirnarily to increased a-adrenergic stimulation in the proximal tubules with secondary increased urea and water reabsorption more distally in the nephron.

BACKGROUND: Obesity is linked to a wide range of respiratory diseases. Several studies have shown that body weight at baseline and weight change were related to pulmonary function. The purpose of this study was to investigate the relationship between change in body mass index (BMI) and pulmonary function in adults. METHODS: Of those aged 40-64 years at baseline who had initially visited the health promotion center at one university-level hospital from January 2000 to December 2002, 499 (men: 309, women: 190) patients revisited the center over a 5-year period up to December 2009 and were enrolled in the study. Subjects were classified into 4 groups- group 1: normal-normal, group 2: normal-obese, group 3: obese-normal, and group 4: obese-obese, based on their BMI at baseline and follow-up. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1/FVC were measured by spirometry. RESULTS: Change in FEV1/FVC was significantly associated with change in BMI for men in all 4 groups. Change in FEV1/FVC was significantly different between group 1 and 3 and between group 1 and 4. Changes in FEV1, FVC and FEV1/FVC were significantly associated with change in BMI for women in all 4 groups. Change in FEV1 was significantly different between group 3 and 4, and change in FVC was significantly different between group 1 and 3. CONCLUSIONS: These results suggest that a change in BMI is negatively associated with change in pulmonary function. Obesity itself can be a risk factor for pulmonary dysfunction, and a decrease in BMI through weight reduction could reduce pulmonary dysfunction or improve pulmonary function in adults.

The Diego blood group system consists of two pairs of antigens, Dia and Dib The incidence of Dia is low among pure Caucasian, Blacks, Polynesian and Eskimo, however, the rnongolians and American indians have both Dia and Dib. We report a case of two days old male who was admitted on first day of life for jaundice and subsquently exchange transfusion was performed on second day of life for bilirubin of 20 mg/dl. The blood groups of patient and his mother were both Rh D positive 0 type. Direct and indirect Coombstest were strong positive in the patient and indirect Coombstest was positive in his mother. We found anti-Dib antibody in his rnother's serum. The phenotype of Diego blood group system of the patient and his mother were Di (a+b+) and Di (a+b- ), respectively and hemolytic anemia in this case was due to anti-Dib antibody.
