Ventricular septal defect remains an infrequent but devastating complication of acute MI. Approximately 1∼3% of cases of acute myocardial infarction are complicated by ventricular septal rupture in the prethrombolytic era and the incidence has decreased to 0.2% with reperfusion therapy. This mechanical complication usually occurs within the first 10 to 14 days when necrotic tissue is most abundant and the collateral coronary circulation is not well developed. This lesion is generally associated with complete coronary obstruction rather than severe stenosis. Rupture of the ventricular septum is a severe mechanical complication of acute myocardial infarction, usually resulting in death unless surgical repair is performed. The bad prognosis of this event within the first 2 weeks indicates the need for early surgical rapair. This complication is more frequent after the first acute myocardial infarction in the elderly and secondary to a transmural myocardial infarction. We report two cases of ventricular septal rupture after acute myocardial infarction.

Avian influenza (AI) and Newcastle disease (ND) distress a variety of avian species, especially domestic poultry. Severe syndromes are caused by highly virulent specific virus strains termed highly pathogenic AI and velogenic ND viruses, which are potential agrobioterrorism agents. This outbreak emphasizes the need for continuing cooperation between public health and veterinary medical communities in controlling AI and ND when it has a zoonotic potential. Up to date, the stamping out and burying system were applied for controlling methods against these highly infectious diseases in the ordinary way, however these methods had many environmental problems, including leachat and effluvium. Thus, we assessed that sterilization effect of AI and ND virus dependent on several treatment conditions, such as autoclaving time and cutting types of chicken. As a result, we found that the cutting type of chicken meat revealed a reduced HA titer (20) against both of AI and ND virus after 10 min of autoclaving, while whole chicken showed same titer after 30 and 60 min. Therefore, we propose that the conditions of treatment on infected chicken should be developed for convenient, affordable, and effective prevention methods against for AI and ND.

Thus, this study purposed to investigate the spawning behavior of C. aeneus albinos and the morphological development of its larvae and juveniles and to use the results as basic data for the growth of fancy fish and taxonomic research. The broodstock (overall length 6.20~7.25 ㎝, mean 6.60±0.35 ㎝) used in this experiment was purchased from an aquarium in Pohang City, Gyeongsangbuk-do in January 2015, and two male and two female individuals were put in a rectangular glass water tank (45×30×35 ㎝) and grown in the type of recirculation. The egg was globular in shape, its color was white and opaque, and it was a demersal egg of high viscosity. Egg size was 1.64~1.82 ㎜ (mean 1.70±0.08 ㎜). Fertilized eggs began to hatch after 50 hours. Pre-larvae just after hatching were 4.35~4.68 ㎜ in overall length (mean 4.43±0.14 ㎜), their mouth and anus did not open, and they kept the yolk. Post-larvae on day 15 after hatching were 9.98~10.2 ㎜ long (mean 10.1±0.09 ㎜), the barbels around the mouth developed like saw teeth, and the dorsal, ventral, and anal fins, which had been membranous, were separated. Juveniles on day 35 after hatching were 18.3~18.7 ㎜ long (mean 18.5±0.16 ㎜). They did not have melanophore throughout the entire body and the gill openings and abdomen were deposited with golden chromophore.

<B>Abstract</B><P>Objective: To elucidate relationships between the dental roots and surrounding tissues in order to prevent complications after placement of a miniscrew.</P><P>Materials and Methods: Twenty human mandibles and maxillas were used for this study. In the 200 sections of each mandible and maxilla, nine items were measured to investigate the relationships between the dental roots.</P><P>Results: The interroot distance increased from anterior to posterior teeth and from the cervical line to the root apex in both the maxilla and the mandible. In the maxilla, the greatest interroot distance was between the second premolar and the first molar. In the mandible, the greatest interroot distance was between the first and second molars. The maxillary buccolingual bone width exceeded 10 mm from 7 mm (between canine and first premolar), 5 mm (between second premolar and first molar), and 4 mm (between first and second molars) above the cervical line. The mandibular buccolingual bone width exceeded 10 mm from 7 mm (between second premolar and first molar) and 4 mm (between first and second molars) below the cervical line.</P><P>Conclusions: The safest zone for placement of a miniscrew in the maxilla was between the second premolar and the first molar, from 6 to 8 mm from the cervical line. The safest zone for placement of a miniscrew in the mandible was between the first and second molars, less than 5 mm from the cervical line.</P>

<P><I>J. Neurochem</I>. (2010) <B>114</B>, 39–50.</P><P>Abstract</P><P>Reactive oxygen species (ROS) actively participate in microglia-mediated pathogenesis as pro-inflammatory molecules. However, little is known about the involvement of specific antioxidants in maintaining the microglial oxidative balance. We demonstrate that microglial peroxiredoxin (Prx) 5 expression is up-regulated by lipopolysaccharide (LPS) through activation of the ROS-sensitive signaling pathway and is involved in attenuation of both microglial activation and nitric oxide (NO) generation. Unlike in stimulation of oxidative insults with paraquat and hydrogen peroxide, Prx V expression is highly sensitive to LPS-stimulation in microglia. Reduction of ROS level by treatment with either NADPH oxidase inhibitor or antioxidant ablates LPS-mediated Prx V up-regulation in BV-2 microglial cells and is closely associated with the activation of the c-<I>jun</I> N-terminal kinase (JNK) signaling pathway. This suggests the involvement of ROS/JNK signaling in LPS-mediated Prx V induction. Furthermore, NO induces Prx V up-regulation that is ablated by the addition of inducible nitric oxide synthase inhibitor or deleted mutation of inducible nitric oxide synthase in LPS-stimulated microglia. Therefore, these results suggest that Prx V is induced by cooperative action among the ROS, RNS, and JNK signaling cascades. Interestingly, knockdown of Prx V expression causes the acceleration of microglia activation, including augmented ROS generation and JNK-dependent NO production. In summary, we demonstrate that Prx V plays a key role in the microglial activation process through modulation of the balance between ROS/NO generation and the corresponding JNK cascade activation.</P>
