Purpose: Cention N (Ivoclar Vivadent) was a recently introduced alkasite-based restorative material that was expected to replace amalgam and glass ionomer cement. This material was an esthetic restoration with adequate mechanical strength and release of fluoride and calcium. The purpose of this study was to measure the water sorption and water solubility of Cention N and evaluate its long-term durability compared to other esthetic restorations (Resin-Modified Glass Ionomer cement [RMGIC], Giomer, Composite Resin). Materials and Methods: Twenty specimens each of Cention N (CN), Resin Modified-Glass Ionomer Cement (FJ), Giomer (BF), and Composite Resin (FZ) were made. After each specimen was completely dried in a desiccator for 24 hours using a vacuum pressure pump, the specimen was weighed (m1). After that, the specimen was immersed in distilled water at 37°C for 7 days, stored in a drying oven, and weighed (m2). After drying completely for 24 hours in a desiccator, the specimen was weighed (m3) to calculate the water absorption and water solubility using Formulas 1 and 2. The measured values were statistically processed and analyzed using SPSS, and the significance level was set at 0.05.Result: When measuring water sorption, FJ (122.61 μg/mm3 ) showed significantly higher water sorption than CN (35.42 μg/mm3 ) (P<0.05). There was no significant difference between FZ (18.03 μg/mm3 ) and BF (14.76 μg/mm3 ) (P=0.930). When measuring water solubility, CN (6.65 μg/mm3 ) showed significantly higher water solubility than FJ (1.47 μg/mm3 ) (P<0.05). Conclusion Cention N had lower water sorption than RMGIC, but higher water solubility, indicating that it is more vulnerable to moisture and has lessened long-term durability.

Although congenital syphilis can be prevented with prenatal screening, the disease remains problematic. Currently, there are no cases that describe hematuria and pneumonia related to congenital syphilis. We report a case of congenital syphilis that involved nephrotic syndrome and pneumonia alba in a 22-day-old male infant whose mother did not receive adequate prenatal care. The congenital syphilis diagnosis was confirmed with a serologic test and the patient recovered with penicillin treatment. Clinical findings may be subtle in neonates and delayed recognition occurs frequently, thus complete prenatal screening is critical for congenital syphilis prevention. Immediate serologic testing should be performed to obtain a differential diagnosis if an infant is delivered by a mother that has not received appropriate prenatal examinations.

Congenital chloridorrhea is a rare autosomal recessive disease and results from impairment of active transport of chloride in the ileum and colon. Absence of the Cl-/HCO3-, exchange pump causes polyhydramnios, distended bowel loop and absence of meconium before birth. Prenatal ultrasound examination shows a great number of circular anechoic area in the fetal abdomen, as well as polyhydramnios. Massive watery diarrhea is apparent from the first days of life. This fluid loss, with its attendant impairment of electrolyte homeostasis, is life threatening. Exact replacement of water, NaCl and KCl can prevent the growth and psychomotor retardation and the development of progressive renal damage. We experienced one case of congenital chloridorrhea and present it with brief review of literatures.

Toxic effects of ozone, 4-(N-methyl-N-nitrosamino)-1-(3- pyridyl)-1-butanone (NNK), and/or dibutyl phthalate (DBP) were examined through NF-kappaB, AP-1, Nrf2, and osteopontin (OPN) in lungs and livers of B6C3F1 mice. Electrophoretic mobility shift assay (EMSA) indicated that mice treated with combination of toxicants induced high NF-kappaB activities. Expression levels of p105, p65, and p50 proteins increased in all treated mice, whereas IkB activity was inhibited in NNK-, DBP-, and combination-treated ones. All treated mice except ozone-treated one showed high AP-1 binding activities. Expression levels of c-fos, c-jun, junB, jun D, Nrf2, and OPN proteins increased in all treated mice. Additive interactions were frequently noted from two-toxicant combination mice compared to ozone-treated one. These results indicate treatment of mixture of toxicants increased toxicity through NF-kappaB, AP-1, Nrf2, and OPN. Our data could be applied to the elucidation of mechanism as well as the risk assessment of mixture-induced toxicity.

Endothelial cells are a vital constituent of most mammalian organs and are required to maintain the integrity of these tissues. These cells also play a major role in angiogenesis, inflammatory reactions, and in the regulation of thrombosis. Angiogenesis facilitates pulp formation and produces the vessels which are essential for the maintenance of tooth homeostasis. These vessels can also be used in bone and tissue regeneration, and in surgical procedures to place implants or to remove cancerous tissue. Furthermore, endothelial cell regeneration is the most critical component of the tooth generation process. The aim of the present study was to stimulate endothelial regeneration at a site of acute cyclophosphamide (CP)-induced endothelial injury by treatment with human umbilical cord-derived endothelial/mesenchymal stem cells (hEPCs). We randomly assigned 16 to 20-week-old female NOD/SCID mice into three separate groups, a hEPC (1 x 10(5) cells) transplanted, 300mg/kg CP treated and saline (control) group. The mice were sacrificed on days 5 and 10 and blood was collected via the abdominal aorta for analysis. The alanine transaminase (ALT), aspartate aminotransferase (AST), serum alkaline phosphatase (s-ALP), and albumin (ALB) levels were then evaluated. Tissue sections from the livers and kidneys were stained with hematoxylin and eosin (HE) for microscopic analysis and were subjected to immunohistochemistry to evaluate any changes in the endothelial layer. CP treatment caused a weight reduction after one day. The kidney/body weight ratio increased in the hEPC treated animals compared with the CP only group at 10 days. Moreover, hEPC treatment resulted in reduced s-ALP, AST, ALT levels compared with the CP only group at 10 days. The CP only animals further showed endothelial injuries at five days which were recovered by hEPC treatment at 10 days. The number of CD31-positive cells was increased by hEPC treatment at both 5 and 10 days. In conclusion, the CP-induced disruption of endothelial cells is recovered by hEPC treatment, indicating that hEPC transplantation has potential benefits in the treatment of endothelial damage.

From Jan. 1991 to Apr. 1996, 99 cases of microsurgical tubal reversal were performed in the Department of Obstetrics and Gynecology, Chunchon Sacred Heart Hospital of Hallym University. 80 cases among them were followed up over 1 year postoperatively. The results were as follows : 1. The mean age of total 99 women was 32.5 years(24~42 years), and the average interval between tubal sterilization and tubal reversal was 7.2 years(1~17 years). 2. The methods of sterilization were laparoscopic fallope ring in 59 cases(59.6 %), laparoscopic electrocautery in 30 cases(30.3 %), tubal ligation during cesarean section in 9 cases(9.1 %) and minilap in 1 case. 3. The most common reason for tubal reversal was remarriage(61 case, 61.6 %) and the next was desire for son(16 cases, 16.2 %). 4. 80 cases(81 %) among the total 99 women were followed up over 1 year postoperatively. Intrauterine pregnancy was documented in 59 cases(73.7 %), 53 viable fetuses and 6 spontaneous abortions. Ectopic pregnancy was noted in 3 cases(3.8 %). 5. Pregnancy rates according to maternal age were as follows ; 88.9 % in less than 30 years, 70.3 % in 30~34 years, 71.4 % in 35~39 years. Two normal pregnancies were resulted from 4 women over 39 years. 6. Pregnancy rates according to the method of sterilization were as follows ; 78 % in fallope ring, 89 % in tubal ligation during cesarean section, 55 % in electrocautery. The statistical differences between each groups were not significant(p = 0.053). 7. Pregnancy rates according to the site of anastomosis were as follows ; 81.4 % in isthmicisthmic, 67.1 % in isthmic-ampulla. There was significant statistical difference between them(p = 0.011). 8. Pregnancy rates according to the postoperative tubal length were as follows ; 60 % in less than 4cm, 66 % in 4~6 cm, 95.4 % in more than 6cm(p = 0.024). 9. Among the 59 pregnant women, 38 pregnancies(65.4 %) were resulted within six months after surgery, 48(82.3 %) within one year, and 55(94.2 %) within 2 years. 10. Pregnancy rates according to the interval from tubal sterilization to tubal reversal were as follows ; 89.6 % in less than 5years of interval, 74.5 % in 5~10 years, 44.4 % in 11~15 years(p = 0.230).
