This study was carried out to investigate the light and electron microscopic findings of the livers of rats after an intraperitoneal injection of cadmium chloride. The Sprague-Dawley rats were intraperitoneally injected with cadmium chloride dissolved in water, once a day for three days. These animals were sacrificed at 1, 3, 8, and 24 hr after the last injection. Control groups of the rats were also sacrificed in the same manner. The liver was extirpated and examined by both light and electron microscopy. The results obtained are as follows: The parenchyma of the liver shows focal neutrophilic infiltration and spotty necrosis. The hepatocytes show fatty change, ballooning degeneration, swelling of the endoplasmic reticulum and mitochondria, increase numbers of secondary lysosomes and residual bodies. Focal patic venules and sinusoids of the liver are congested. The Kupffer cells are increase in number. Therefore, it can be concluded that the cadmium is directly acted to hepatocytes resulting in cellular injuries and deposits in the fat droplets of the cytoplasm of the hepatocytes, not Ito cells as previously suggeted.

Authors experienced a case of acute optic neuritis, 12 years old female patient, following scarlet fever which is rare among bacterial origin in ophthalmological aspects. On the first day of admission, the visual acuities of 0.04(N.C.) in right eye and 0.2 (N.C.) in left eye, blurring of disc margins (OU), central scotoma (OD), and high antistreptolysin O titer (A.S.T.O.) were noted. After bed rest and medical treatment with corticosteroid, penicillin, and vitamin B12 for two and a half months, the visual acuities and antistreptolysin O titer were recovered completely.

The Korean Rice Ds-tagging lines Database (KRDD) is designed to provide information about Ac/Ds insertion lines and activation tagging lines using japonica rice. This database has provided information on 18,158 Ds lines, which includes the ID, description, photo image, sequence information, and gene characteristics. The KRDD is visualized using a web-based graphical view, and anonymous users can query and browse the data using the search function. It has four major menus of web pages: (i) a Blast Search menu of a mutant line; Blast from rice Ds-tagging mutant lines; (ii) a primer design tool to identify genotypes of Ds insertion lines; (iii) a Phenotype menu for Ds lines, searching by identification name and phenotype characteristics; and (iv) a Management menu for Ds lines.

BACKGROUND AND OBJECTIVES: Coronary flow reserve (CFR) is considered an important index of the functional significance of coronary artery stenosis, but is influenced by several factors, such as left ventricle hypertrophy (LVH), diabetes mellitus (DM), hyperlipidemia and smoking. Measurement of the coronary flow velocity of the left anterior descending coronary artery (LAD) by transthoracic Doppler echocardiography (TTDE) is feasible, and provides reliable information. The purpose of this study was to investigate the relationship between CFR and LVH, DM, hyperlipidemia and hypertension in patients with or without coronary artery disease, and to assess the prominent factors influencing CFR. SUBJECTS AND METHODS: Coronary angiographies were performed in 38 patients to evaluate chest pain. The distal LAD flow velocity was measured by TTDE, and the CFR calculated as a ratio of the hyperemic and baseline mean diastolic velocities. The CFR was compared with clinical, echocardiographic and angiographic parameters. RESULTS: The CFR was similar in patients both with and without hypertension, DM, high LDL-cholesterol levels and low ejection fraction(<40%). The mean CFR was lower in patients with (50% LAD stenosis than in patients with no significant stenosis. The CFR of patients with a left ventricle wall thickness of (12mm was lower than in those without LVH. The multivariate analysis of the aforementioned factors showed that LVH was the factor most influencing to the CFR (p<0.05). CONCLUSION: When using CFR as a functional parameter of LAD stenosis, one should consider LVH as one of the factors attributed to CFR modification.

Background and Objectives: The aim of this study was to demonstrate the efficacy and safety of treatment with drug-coated balloon (DCB) in a large real-world population. Methods: Patients treated with DCBs were included in a multicenter observational registry that enrolled patients from 18 hospitals in Korea between January 2009 and December 2017. The primary outcome was target lesion failure (TLF) defined as a composite of cardiovascular death, target vessel myocardial infarction, and clinically indicated target lesion revascularization at 12 months. Results: The study included 2,509 patients with 2,666 DCB-treated coronary artery lesions (1,688 [63.3%] with in-stent restenosis [ISR] lesions vs. 978 [36.7%] with de novo lesions).The mean age with standard deviation was 65.7±11.3 years; 65.7% of the patients were men.At 12 months, the primary outcome, TLF, occurred in 179 (6.7%), 151 (8.9%), 28 (2.9%) patients among the total, ISR, and de novo lesion populations, respectively. A history of hypertension, diabetes, acute coronary syndrome, previous coronary artery bypass graft, reduced left ventricular ejection fraction, B2C lesion and ISR lesion were independent predictors of 12 months TLF in the overall study population. Conclusions This large multicenter DCB registry study revealed the favorable clinical outcome of DCB treatment in real-world practice in patient with ISR lesion as well as small de novo coronary lesion.
