AIM： To investigate the role of Sonic hedgehog （Shh） on the course of liver ischemia and reperfusion （I/R） in rats, and the interaction between treatment with nitric oxide donor L-Arginine-methyl ester （L-Arg） and up-regulation of Shh expression.METHODS： A total of 30 male Sprague-Dawley rats weighing 220-240 g were used in this study. Shamcontrol group （G1, n = 10）： a sham operation was performed （except for liver I/R）. I/R-untreated group （G2, n = 10）： rats underwent liver ischemia for 1 h followed by reperfusion for 45 min. I/R-L-Arg group （G3, n = 10）： after performing the same surgical procedure as in group 2, animals were treated with L-Arg. Liver tissues were taken for determination of malondialdehyde （MDA） levels, and biochemical and histological evaluations were made.RESULTS： Plasma alanine aminotransferase （ALT）, aspartate aminotransferase （AS-T）, lactate dehydrogenase （LDH） and T-glutamyltranspeptidase （GGT） activities were higher in group 2 than in group 3. MDA values and the hepatic injury score decreased in the L-Arg treated group compared to the I/R-untreated group. In group 2, the hepatoo/tes were swollen with marked vacuolization. Group 3 rats showed well-preserved liver parenchyma, with hepatocytes extending from the central vein. The morphology of the hepatocytes and the sinusoidal structures was normal, without any signs of congestion. Mild Shh positive immunostaining was detected in group 2 animals. The expression of immunoreactive cells was increased markedly in liver tissue from I/R-L-Arg rats.CONCLUSION： Our findings suggest that Shh molecules are critical factors in the pathophysiology of inflammatory liver injury induced by I/R. In addition, NO plays an important role in the immunohistochemical expression of these molecules.

Most of the foreign bodies detected in adult gastroin- testinal systems are accidentally swallowed pins. In this study, we presented a case with intracolonic multiple pebbles. A 20-year-old man was admitted to emergency surgery policlinic for abdominal pain for 2 d without any alleviation or aggravation. His upright plain abdominal radiographic imaging revealed about 30-40 overt dense opacities in lumen of colonic segments, with oval and well shaped contours, each approximately 1 cm × 1 cm in size. The multiplanar reconstructions and three- dimensional images combined with sectional screening showed that all pebbles had passed completely into the colon and no foreign bodies had remained in the ileal segments. On psychiatric assessment, he was found to have immature personality features, difficulty in over- coming stressors and adaptation disorder. He recovered by conservative management and radiographic monitoring applied during his follow-up. Thus, it can be concluded that, in differential diagnosis of abdominal pain in adult ages, though less frequently seen than in children, gastrointestinal system foreign bodies should always be kept in mind and it should be considered that ingestion of pebbles may be one of the factors contributing to abdominal pain particularly in young adults with psychiatric problems. In such cases suspected of having foreign bodies which cannot be detected by plain films, abdominal tomography can be an alternative for diagnostic imaging.

AIM： TO investigate the agreement between esophageal manometry and pH step-up method in two different patient positions. METHODS： Eighteen subjects were included in the study. First, the distance from the nose to the proximal border of the lower esophageal sphincter （LES） was measured manometrically. Then a different investigator, who was blinded to the results of the first study, measured the same distance using the pH step-up method, with the patient in both upright and supine positions. An assessment of agreement between the two techniques was performed. RESULTS： In the supine position, the measurement of only one subject was outside the range accepted for correct positioning （~〈 3 cm distal or proximal to the LES）. In the upright position, errors in measurement were recognized in five subjects. Bland-Airman plots revealed good agreement between measurements obtained manometrically and by the pH-step up method with the patient in the supine position. CONCLUSION： In the case of nonavailability of manometric detection device, the pH step-up method can facilitate the positioning of the 24 h pH monitoring catheter with the patient in the supine position. Thisshould increase the use of pH-metry in clinical practice for subjects with suspected gastroesophageal reflux disease if our results are supported by further studies.

AIM:To investigate the role of fundus autofluo rescence(FAF) both in the diagnosis and the preoperative and postoperative evaluation of patients with idiopathic macular hole(MH).METHODS:Forty eyes of 40 patients diagnosed as idiopathic MH between May 2010 and May 2011 were included in this retrospective *** patients underwent full ophthalmologic examinations and imagings including fluorescein angiography,fundus autofluorescence(FAF) and optical coherence *** of these patients underwent MH *** findings were associated with duration of symptoms,visual acuity at presentation,stage of MH,and postoperative anatomical ***:The mean duration of patients’ symptoms was 3.8±2.0(1-9) *** MH was stage 2 in 4(10%),stage 3 in 24(60%) and stage 4 in 12(30%) *** median preoperative best corrected visual acuity was 20/200(between 20/800 and 20/100).Twenty-eight of cases(70%) showed a stellate appearance with dark radiating *** a visual acuity ≥20/200 was significantly more common in eyes with stellate appearance(P<0.001).The mean duration of symptoms was significantly shorter in eyes with stellate appearance(2.75±0.8 vs 6.33±1.61 months)(P<0.001).The frequency of stage 4 MH was significantly higher in eyes with nonstellate appearance(P<0.001).Anatomical correction of MH was achieved in 91.3%(21/23) of eyes with stellate appearance and 71.4%(5/7) of eyes without this appearance(P=0.225).CONCLUSION:Stellate appearance in FAF is associated with earlier stages of macular hole,better visual acuity at presentation,shorter duration of symptoms,thus more favorable prognosis.
