BACKGROUND: We evaluated 1) the sequential changes of angiotensin-converting enzyme (ACE) mRNA expression in lung (main site for circulating ACE synthesis) and left ventricle, and 2) whether such expression is modified by ACE inhibitor or angiotensin II receptor blocker treatment after acute myocardial infarction (MI) in rats. METHODS: Placebo, captopril (2 g/liter drinking water) or TCV-116 (10 mg/kg/day gavage) was administered 3 days before left coronary occlusion and continued for 6 weeks. At 1, 3 and 6 weeks after operation, hemodynamic measurement was performed and pulmonary and myocardial ACE mRNA expression was analyzed by quantitative RT-PCR using rcRNA as an internal standard. RESULTS: Mean BP and LVEDP increased in untreated rats compared with captopril- and TCV-116-treated rats (post-MI 6week, p<0.05). Pulmonary ACE mRNA increased in acute phase (post-MI 1 week, max. 1.4 fold, p<0.05 vs. pre-MI) and returned to pre-MI value thereafter. In contrast, cardiac ACE mRNA expression showed slightly decreasing tendency in acute phase, and was increased up to 1.6 fold in chronic phase after MI (post-MI 3 and 6weeks, p<0.05 vs. pre-MI). No changes in pulmonary ACE gene expression were found with RAS blockade. However, in acute phase after MI, cardiac ACE mRNA increased with both captopril and TCV-116 treatment (post-MI 24hour and 1week, max. 2 fold, p<0.05 vs. untreated group). CONCLUSION: 1) In contrast to the pulmonary ACE mRNA that is activated in acute phase, the cardiac ACE mRNA is activated in chronic phase after MI. 2) RAS blockade does not affect the change of pulmonary ACE expression, but modulate the change of cardiac ACE expression after MI.

Background:
The medial temporal region is the earliest affected structure in patients with Alzheimer’s disease (AD), and its atrophy is known as the hallmark of AD. This study aimed to investigate the value of medial temporal atrophy (MTA) for detecting 18F-florbetaben positron emission tomography (PET)-proven AD pathology.
Methods:
We retrospectively enrolled 265 subjects complaining of cognitive decline at a dementia outpatient clinic from March 2015 to December 2017. All subjects underwent brain magnetic resonance imaging, 18F-fluorodeoxyglucose PET, and 18F-florbetaben PET at baseline. We performed multivariable logistic regression analyses on variables including age, sex, years of education, white matter hyperintensities, apolipoprotein E (APOE) genotype, and memory composite scores in various combinations to investigate whether MTA was indicative of underlying AD pathology.
Results:
Our sample population of 265 patients comprised 121 with AD-related cognitive impairment, 42 with Lewy bodies-related cognitive impairment, 32 with vascular cognitive impairment, and 70 with other or undetermined pathologies. In the multivariable logistic regression analyses, MTA was not an independent predictor of underlying AD pathology (P>0.200). The predictive power of underlying AD-related cognitive impairment significantly increased when multiple variables including APOE genotype and memory composite scores were considered together (area under the curve >0.750).
Conclusion
Our results suggest that MTA alone may be insufficient to accurately predict the presence of AD pathology. It is necessary to comprehensively consider various other factors such as APOE genotype and a detailed memory function to determine whether the patient is at high risk of AD.

About 15 to 20% of ovarian tumors are of germ cell origin, and about 95% of these are cystic teratoma. when the teratoma is composed either entirely or predominantly of thyroid tissue, it called struma ovarii. Struma ovarii represents about 2.7% of cystic teratoma. The incidence of malignant struma ovarii is probably much less than 5% of all struma ovarii. We have observed a case of malignant struma ovarii originated from the left ovary of a 46-year-old woman, and present this case with a brief review of concerned literatures.

Gastritis cystica profunda (GCP) is a rare disease which is mainly observed at the site of gastroenterostomy. However, it may occur in the stomach without a previous history of surgery. Under histologic examination GCP shows hyperplastic and cystic dilatation of the pseudopyloric glands with submucosal invasion. GCP with sessile polypoid pro-trusion is most commonly found but, submucosal tumors, giant gastric mucosal folds and pedunculated forms are occasionally found. We present the case of GCP showing a large sized polyp (3 2.5 2.5 cm) with a long pendulous pedicle that had developed in the fundus of the stomach without previous surgical history. Endoscopic polypectomy was performed for confirmation.

A congenital ureteral valve is a rare disease, with the first case presented in 1887, since when, only 42 cases have subsequently been reported. From a review of the reported cases, this abnormality was often found to be associated with other urological disorders, such as vesicoureteral reflux, ectopic ureter, complete and incomplete duplication of the kidney, and contralateral renal atrophy. Here, the case of an adult patient with multiple congenital ureteral valves and renal atrophy is reported.
