The purpose of this study was to assess and compare the osseous responses to implanted particles of porous synthetic HA(Interpore 200(R), Interpore International, U.S.A.), resorbable natural bovine derived HA(Bio-oss(R), Gestlich Pharma, Switzerland) and calcium carbonate(Biocoral 450(R), Inoteb, France) in bone defects. Four calvarial defects of 2.5mm diameter were created in each of 16 Sprague-Dawley rats. The experimental materials were subsequently implanted in three defects, leaving the fourth defect for control purpose. Four animals were each sacrificed at 3 days, 1week, 2weeks and 4 weeks after surgery. The tissue response was evaluated under light microscope. Overall, histologic responses showed that all the particles were well tolerated and caused no aberrent tissue responses. There were difference in the amount of newly formed bone at the experimental sites and control site. There was more new bone formation associated with calcium carbonate site. In addition, the calcium carbonate site displayed multinucleated giant cells surrounding calcium carbonate particles after the 1st week, and osteoid tissue within the particle after the 2nd week. After 4 weeks, calcium carbonate particles were resorbed and replaced with new bone. The healing of the natural bovine derived HA site was similar to that of porous synthetic HA, except that new bone growth between the two particles have progressed more in the former site after the 2nd week. In the natural bovine derived HA site, the particle was surrounded by newly formed bone after the 4th week. After 4 weeks, the control site showed more mature bone than other sites. In conclusion, the grafted sites were better in new bone formation than non-grafted sites. In particular the calcium carbonate site showed the ability of osteoinduction and natural bovine derived HA showed osteoconduction in rat calvarial defects. This suggest that calcium carbonate and natural bovine derived HA could enhance the regenerative potential in periodontal defects.

Acardic twining is a rare congenital anomaly, usually in monozygotic twins. This condition is characterized by the absence or rudimentary development of fetal hear, and associated with various anomaly(especially with anecephalus). The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. We recently experienced a case of acardius acephalus associated with a normal term male infant, so present with a brief review of the literature.

Hepatoid adenocarcinoma of the stomach is a gastric carcinoma with both adenocarcinomatous and hepatocellular carcinomatous differentiation. It usually produces large amount of serum alpha-fetoprotein. It often occurs in aged person, commonly located in the gastric antrum. Because of early lymph node and liver metastasis, prognosis is poor. A case of hepatoid adenocarcinoma of the stomach in a 49-year-old man is reported. The patient's serum alpha-fetoprotein level was high(3380ng/ml). Liver function test was normal, otherwise. A mass was observed in right lobe of the liver on US and CT. It was hypervascular with increased uptake of lipiodol on hepatic arteriography. A large ulcerative tumor involving the gastric antrum and body was also found at barium study of the stomach. Subtotal gastrectomy and right Iobectomy of the liver resulted in rapid decrease in serum alpha-fetoprotein. Histopathologically the diagnosis was hepatoid adenocarcinoma of the stomach with liver metastasis.

The authors introduced flip back spin echo (FBSE) technique for MR imaging of the temporomandibular joint (TMJ) instead of conventional spin echo (SE) technique, and evaluated whether FBSE technique in MRI of TMJ is adequate for the diagnosis of the disorders or not. FBSE T1 parasagittal images in closed mouth state and sequential opening and closing mouth states using patient's own finger(s) were obtained and then FBSE T1 paracoronal image in closed mouth state and STAGE(short tip angle gradient echo) parasagittal T2WI were followed. All 30 images of the symptomatic TMJs using FBSE technique were excellent in the visualization of articular and their displacement, and we could easily diagnose the internal derangement. FBSE technique was adequate for the diagnosis of internal derangement of the TMJ, and the modified cine display from images using FBSE technique was advantageous in the diagnosis of the disorders by visualization of the dynamic motion of the TMJ.

PURPOSE: This study was done to assess effects of women focused relapse prevention program on abstinence self-efficacy and depression in alcoholic women. METHODS: This study was a non-equivalent control group non-synchronized design with two groups, an experimental group (13 patients) and a control group (16 patients). The instruments were the Situational Confidence Questionnaire (SCQ-39) and the Beck depression Inventory (BDI). Data collection was done between July and December, 2008, during which a pre-test, the total of 8 group sessions for four weeks, and a post-test were given to alcoholic women who were admitted to K hospital in U city and D hospital in G city. The collected data were analyzed using descriptive statistics, Fisher's exact test, Mann-Whitney U test and ANCOVA with SPSS/WIN program. RESULTS: The scores for abstinence self-efficacy were significantly higher and for depression lower, for the experimental group after the women focused relapse prevention program. CONCLUSION: This study shows that the women focused relapse prevention program can be applied as an effective nursing intervention by clinical nurses.
