Abstract
UNLABELLED Because the rate of bone loss is an important risk factor for fracture, we studied longitudinal changes in bone mineral density (BMD). Although the BMD of the hip decreased over time, spine BMD remained largely stable or increased. Therefore, spine BMD may not be appropriate for assessing BMD change. INTRODUCTION The rate of age-dependent bone loss has been shown to be an important risk factor for fracture. However, longitudinal rates of BMD loss in Korea have not yet been reported. The objective of this study was to evaluate longitudinal changes in BMD in Korea. METHODS This cohort study was performed in a population of individuals 40 years of age or older living in the rural area of Chungju City, Korea. A second BMD examination was conducted approximately 4 years after a baseline examination. A total of 3755 of the 6007 subjects completed the follow-up visit, corresponding to a follow-up rate of 62.51%. RESULTS The age-standardized osteoporosis prevalence was 12.81% in males and 44.35% in females. In males, the average annual BMD loss at the total hip increased from -0.25% per year in their 40s to -1.12% per year in their 80s. In females, the average annual BMD loss at the total hip increased from -0.69% per year in their 40s to -1.51% per year in their 80s. However, the average annual percentage change in spine BMD in females increased from -0.91% per year in their 40s to +1.39% per year in their 80s. CONCLUSIONS A substantial number of subjects had osteoporosis, even though we standardized the prevalence of osteoporosis. In total hip, the mean BMD was decreased during the follow-up period; in addition, the annual percentage loss increased with age. However, spine BMD remained approximately stable or increased over time and therefore may not be appropriate for assessing BMD change.

Abstract
BACKGROUND AND PURPOSE Antiplatelet resistance is known to be associated with symptomatic ischemic complication after endovascular coil embolization. The purpose of our study was to evaluate the relationship between antiplatelet resistance and clinically silent thromboembolic complications using DWI in patients who underwent coil embolization for unruptured intracranial aneurysm. MATERIALS AND METHODS Between October 2011 and May 2013, 58 patients with 62 unruptured aneurysms who were measured for antiplatelet response using VerifyNow assay and underwent elective coil embolization for an unruptured aneurysm with posttreatment DWI were enrolled. Diffusion-positive lesions were classified into 3 groups according to the number of lesions (n=0 [grade 0], n<6 [grade I], and n≥6 [grade II]). The relationship between antiplatelet resistance and diffusion-positive lesions was analyzed. RESULTS Sixty-two endovascular coiling procedures were performed on 58 patients. Clopidogrel resistance was revealed in 23 patients (39.7%) and diffusion-positive lesions were demonstrated in 28 patients (48.3%); these consisted of 19 (32.8%) grade I and 9 (15.5%) grade II lesions. Clopidogrel resistance was not relevant to the development of any diffusion-positive lesion (grade I and II, P=.789) but was associated with the development of multiple diffusion-positive lesions (grade II, P=.002). In the logistic regression prediction model, clopidogrel resistance showed significant correlation with the development of grade II lesions (P=.001). CONCLUSIONS Multiple diffusion-positive lesions (≥6 in number) occurred more frequently in patients with clopidogrel resistance after endovascular coiling for unruptured aneurysms.

Abstract
AIM The inhibition of advanced glycation end products (AGEs) and the receptor for AGEs (RAGE) mediated downstream signaling pathways have been suggested to have retinoprotective actions in diabetic retinopathy. Herein, we examined the protective effects of aminoguanidine (AG), an AGEs inhibitor, on diabetes-induced injury of retinal ganglion cells in the Zucker diabetic fatty (ZDF) rats. MATERIALS AND METHODS Seven-week-old male ZDF rats were treated with AG (50 mg/kg body weight) once a day orally for 13 weeks. Serum and vitreous concentration of AGEs were examined. Expressions of AGEs and its receptor (RAGE) were assessed by immunohistochemistry. Southwestern histochemistry was used to detect activated nuclear factor (NF)-κB. RESULTS At the end of the study, vitreal levels of AGEs were significantly reduced in ZDF rats treated with AG. Similary, immunohistochemical analysis showed that AG significantly reduced the positive areas for AGEs and RAGE. Furthermore, AG strongly inhibited the loss of retinal ganglion cells by apoptosis. AG also suppressed the activation of to NF-κB. CONCLUSIONS Our results suggest that AG has retinoprotective properties through not only direct inhibition of AGEs formation but also downregulation of NF-κB.

Abstract
AIM AMP-activated protein kinase (AMPK) activators have shown potential as therapeutic agents for metabolic disorders. This study was conducted to evaluate therapeutic potential of panduratin (PAN) A, a natural AMPK stimulator, with activation of PPARα/δ for the treatment of obesity. METHODS We used the novel AMPK activator PAN A, a natural compound isolated from Boesenbergia pandurata rhizomes, to investigate the regulation of LKB1-dependent AMPK-PPARα/δ signalling by western blot, reporter gene assay and small interfering RNA knockdown analysis. In addition, the antiobesity effects of PAN A were evaluated in C57BL/6J mice with high-fat diet (HFD)-induced obesity. RESULTS PAN A stimulated AMPK signalling, induced nuclear translocation of the AMPKα2 subunit and activated PPARα/δ; LKB1, a kinase that lies upstream of AMPK, mediated these effects. PAN A stimulated the direct binding of the AMPKα2 subunit to PPARα/δ, but PPARδ activation required direct interaction with PPARγ coactivator 1α (PGC-1α). Further, PAN A (50 mg/kg/day) reduced weight gain, fat mass, fatty liver and improved serum lipid profiles in obese mice. Additionally, PAN A reduced ectopic fat accumulation and increased the proportion of slow-twitch myofibres and mitochondria content in skeletal muscle, thereby increasing running endurance. CONCLUSIONS PAN A, an LKB1-dependent AMPK stimulator, activated PPARα/δ and attenuated HFD-induced obesity and dysregulation of lipid metabolism. Our findings suggest that PAN A is a potent AMPK activator and show a novel molecular mechanism for the treatment of metabolic disorders.

Abstract
The conformation and dynamics of a single DNA molecule undergoing oscillatory pressure-driven flow in microfluidic channels is studied using Brownian dynamics simulations, accounting for hydrodynamic interactions between segments in the bulk and between the chain and the walls. Oscillatory flow provides a scenario under which the polymers may remain in the channel for an indefinite amount of time as they are stretched and migrate away from the channel walls. We show that by controlling the chain length, flow rate and oscillatory flow frequency, we are able to manipulate the chain extension and the chain migration from the channel walls. The chain stretch and the chain depletion layer thickness near the wall are found to increase as the Weissenberg number increases and as the oscillatory frequency decreases.

Abstract
We experienced 2 cases of septic children after open heart surgery. Both of them recovered by using exchange blood transfusion technique. We use irradiated and dialysed fresh blood for exchange blood transfusion. After this procedure, they recovered from sepsis, as the datas improving, white blood cell reduced from 19,700 +/- 3,710 to 8,200 +/- 2,360, CRP reduced from 5.46 +/- 1.65 to 1.89 +/- 0.70, T-Bil reduced from 7.61 +/- 2.66 to 3.02 +/- 0.89, and BUN reduced from 525.92 +/- 6.64 to 19.76 +/- 5.34. Furthermore, blood pressure and urine volume were stable between exchange blood transfusion, although after open heart surgery. Therefore this procedure has benefits for the compromised, septic patients, performed open heart surgery, because of its stability of the circulating circumstances. And using the irradiated and dialysed fresh blood provides stable condition eventhough under high dose catecholamine use.

Abstract
Proteins containing PDZ (postsynaptic density-95, discs large, zonula occludens) domains play a general role in recruiting receptors and enzymes to specific synaptic sites. In Caenorhabditis elegans, a complex of three PDZ proteins, LIN-2/7/10, mediates basolateral targeting of a receptor tyrosine kinase. Homologs of these LIN proteins have also been identified in higher organisms, and here we analyze the MALS/Veli (mammalian LIN-7/vertebrate homolog of LIN-7) proteins in brain. Immunohistochemical staining and in situ hybridization show that MALS occur differentially in discrete populations of neurons throughout the brain. Most neurons express only one MALS protein, although some cells contain two or even all three MALS isoforms. At the subcellular level, MALS proteins are found in both dendritic and axonal locations, suggesting that they may regulate processes at both pre- and postsynaptic sites. Targeted disruption of MALS-1 and MALS-2 does not yield a detectable phenotype, and hippocampal synaptic function and plasticity are intact in the MALS-1/2 double knockouts. Interestingly, MALS-3 protein is dramatically induced in the MALS-1/2 double knockouts, implying that dynamic changes in protein expression may play an important regulatory role for this family of synaptic PDZ proteins.

Abstract
The actinin-associated LIM protein, ALP, is the prototype of a large family of proteins containing an N-terminal PDZ domain and a C-terminal LIM domain. These PDZ-LIM proteins are components of the muscle cytoskeleton and occur along the Z lines owing to interaction of the PDZ domain with the spectrin-like repeats of alpha-actinin. Because PDZ and LIM domains are typically found in proteins that mediate cellular signaling, PDZ-LIM proteins are suspected to participate in muscle development. Interestingly the ALP gene occurs at 4q35 near the heterochromatic region mutated in facioscapulohumeral muscular dystrophy, indicating a possible role for ALP in this disease. Here, we describe the generation and analysis of mice lacking the ALP gene. Surprisingly, the ALP knockout mice show no gross histological abnormalities and maintain sarcolemmal integrity as determined by serum pyruvate kinase assays. The absence of a dystrophic phenotype in these mice suggests that down-regulation of ALP does not participate in facioscapulohumeral muscular dystrophy. These data suggest that ALP does not participate in muscle development or that an alternative PDZ-LIM protein can compensate for the lack of ALP.

Abstract
Protein assembly at the postsynaptic density (PSD) of neuronal synapses is mediated in part by protein interactions with PSD-95/discs large/zona occludens-1 (PDZ) motifs. Here, we identify MALS-1, -2, -3, a family of small synaptic proteins containing little more than a single PDZ domain. MALS-1, -2, and -3 are mammalian homologs LIN-7, a Caenorhabditis elegans protein essential for vulval development. In contrast to functions for LIN-7 in epithelial cells, MALS-1 and -2 are selectively expressed in specific neuronal populations in brain and are enriched in PSD fractions. In cultured hippocampal neurons, MALS proteins are clustered together with PSD-95 and NMDA type glutamate receptors, consistent with a postsynaptic localization for MALS proteins. Immunoprecipitation and affinity chromatography studies readily identify association of MALS with PSD-95 and an NMDA receptor subunit. The PDZ domain of MALS selectively binds to peptides terminating in E-T/S-R/X-V/I/L, which corresponds to the C terminus of NMDA type 2 receptors and numerous other ion channels at the PSD. This work suggests a role for MALS proteins in regulating recruitment of neurotransmitter receptors to the PSD.

Abstract
Nae I protein was originally isolated for its restriction endonuclease properties. Nae I was later discovered to either relax or cleave supercoiled DNA, depending upon whether Nae I position 43 contains a lysine (43K) or leucine (43L) respectively. Nae I-43K DNA relaxation activity appears to be the product of coupling separate endonuclease and ligase domains within the same polypeptide. Whereas Nae I relaxes supercoiled DNA like a topoisomerase, even forming a transient covalent intermediate with the substrate DNA, Nae I shows no obvious sequence similarity to the topoisomerases. To further characterize the topoisomerase activity of Nae I, we report here that Nae I-43K changes the linking number of a single negatively supercoiled topoisomer of pBR322 by units of one and therefore is a type I topoisomerase. Positively supercoiled pBR322 was resistant to Nae I-43K. At low salt concentration Nae I-43K was processive; non-saturating amounts of enzyme relaxed a fraction of the DNA. At high salt concentration the same non-saturating amounts of Nae I-43K partially relaxed all the DNA in a step-wise fashion to give a Gaussian distribution of topoisomers, demonstrating a switch from a processive to a distributive mode of action. Nae I-43K decatenated kinetoplast DNA containing nicked circles, implying that Nae I-43K can cleave opposite a nick. The products of the reaction are decatenated nicked circles under both processive and distributive conditions. The behavior of Nae I-43K is consistent with that of a prokaryotic type I topoisomerase.

Abstract
Substituting lysine for leucine at position 43 (L43K) transforms NaeI from restriction endonuclease to topoisomerase and makes NaeI hypersensitive to intercalative anticancer drugs. Here we investigated DNA recognition by Nael-L43K. Using DNA competition and gel retardation assays, NaeI-L43K showed reduced affinity for DNA substrate and the ability to bind both single- and double-stranded DNA with a definite preference for the former. Sedimentation studies showed that under native conditions NaeI-L43K, like NaeI, is a dimer. Introduction of mismatched bases into double-stranded DNA significantly increased that DNA's ability to inhibit NaeI-L43K. Wild-type NaeI showed no detectable binding of either single-stranded DNA or mismatched DNA over the concentration range studied. These results demonstrate that the L43K substitution caused a significant change in recognition specificity by NaeI and imply that NaeI-L43K's topoisomerase activity is related to its ability to bind single-stranded and distorted regions in DNA. A mechanism is proposed for the evolution of the NaeI restriction-modification system from a topoisomerase/ligase by a mutation that abolished religation activity and provided a needed change in DNA recognition.

Abstract
A single amino acid change transforms restriction enzyme NaeI to a topoisomerase and recombinase (NaeI-L43K) that shows no sequence similarity to these protein families. This transformation appears to result from coupled endonuclease and ligase domains. To further elucidate the relationship between NaeI-L43K and the topoisomerase protein family, we studied the effect of the topoisomerase inhibitors on NaeI-L43K activity. The intercalative drugs amsacrine, ellipticine, and daunorubicin inhibited NaeI-L43K, whereas the nonintercalating drugs camptothecin, VP-16, and oxolinic acid did not. Ethidium bromide also inhibited NaeI-L43K, implying that intercalation is responsible for its inhibition. The effects of the intercalative drugs on the DNA cleavage steps of NaeI and NaeI-L43K were compared. The drugs hardly inhibited DNA cleavage by wild type NaeI but completely inhibited DNA cleavage by NaeI-L43K. This difference in inhibition demonstrates that the L43K amino acid change sensitized NaeI to these drugs. Low concentrations of the intercalative drugs, except for ethidium bromide, enhance production of topoisomerase--DNA covalent intermediates but inhibited production of the NaeI-L43K--DNA covalent intermediate. These results imply some unique differences between DNA relaxation by NaeI-L43K and DNA topoisomerase. Concomitant with studying inhibition of the cleavage intermediate, NaeI-L43K was found to covalently bond with the 5' end of the cleaved DNA strand.

Abstract
Nae I endonuclease must bind to two DNA sequences for cleavage. Examination of the amino acid sequence of Nae I uncovered similarity to the active site of human DNA ligase I, except for leucine 43 in Nae I instead of the lysine essential for ligase activity. Changing leucine 43 to lysine 43 (L43K) changed Nae I activity: Nae I-L43K relaxed supercoiled DNA to yield DNA topoisomers and recombined DNA to give dimeric molecules. Interruption of the reactions of Nae I and Nae I-L43K with DNA demonstrated transient protein-DNA covalent complexes. These findings imply coupled endonuclease and ligase domains and link Nae I endonuclease to the topoisomerase and recombinase protein families.

Abstract
Tietze's disease (TD) is a self-limited, non-specific, inflammatory condition of the upper costochondral junction (CCJ). Unlike in many other skeletal diseases, radiography plays a relatively minor role in TD because radiographic changes are frequently obscured by physiological costochondral calcifications. Bone scanning is a sensitive test for TD, but its specificity is low. The present study has been conducted to assess prospectively whether pinhole scintigraphy (PS) can enhance diagnostic specificity in TD. Both planar and PS bone images were obtained in seven ribs of five patients with TD. Scans alterations were analyzed and compared with the radiographic findings. Planar scans showed "hot" areas in the region of the CCJ in all seven ribs, these hot areas lacking textural patterns. However, the magnified PS images of the CCJ showed two characteristic uptake patterns: drumstick-like uptake in acute cases and C- or inverted C-shaped uptake in chronic cases. Radiographically, chondritic sclerosis could be seen when physiological chondral calcifications were minimal or absent, but was observed when the calcification was prominent. The correlation of PS and radiographic findings revealed that C- or inverted C-shaped uptake indeed faithfully reflected the inflammatory process in the CCJ, the medial border of which is concave. The further correlation of magnetic resonance and PS images of two lesions in one patient in whom histological examination was performed showed that C- or inverted C-shaped uptake is closely associated with hypervascularity of TD. Differential diagnosis between TD, fracture and metastasis is discussed.

Abstract
A clinical trial was carried out for a lypophilized inactivated hepatitis A vaccine in order to confirm its safety and antibody response. The vaccine used for the study has been developed by Denka Institute of Biological Science (Lot. D-01), Chiba Serum Institute (Lot. C-01) and The Chemo-Sero-Therapeutic Research Institute (Lot. K-02). Thirty-six volunteers were selected and employed for the present study from healthy male adults carrying no antibody against hepatitis A virus (HAV). They were divided into three dose groups; 1.0 microgram, 0.5 microgram and 0.25 microgram viral protein respectively. Each groups were injected intramuscularly 3 times with 0, 1 and 6 months interval. As the results, though, slight side effects such as local pain were found in 16 cases out of 99 total injected, but no abnormal value was observed in the blood and urine examinations. On the other hand, the mean values of serum anti-HAV at 2 months after the first injection in 1.0 microgram, 0.5 microgram and 0.25 microgram dose-groups were 562 mIU/ml, 323 mIU/ml and 134 mIU/ml, respectively, and at the 7 months, 3630 mIU/ml, 1288 mIU/ml and 1000 mIU/ml, respectively. Namely, the high immunogenicity and safety of the vaccine were confirmed in this trail.

Abstract
A previously healthy 40-year-old woman was admitted with severe dyspnea, cough and slight fever. Chest X-ray film revealed bilateral widespread opaque infiltration with ground glass shadows around it. The laboratory examination showed moderate hepatic and muscular injury with disseminated intravascular coagulation. In addition her arterial blood gas showed severe hypoxemia (PaO2: 25 Torr under room air). Moreover, about 1 week prior to admission, 2 baby budgerigars she had been raising for half a year died. Because of this history and multi-organ injuries, this disease was considered to be acute pneumonia owing to fulminant psittacosis causing acute respiratory failure. On the first day of admission, she was intubated and ventilated mechanically with an oxygen concentration (FIO2) of 100%. Subsequently, treatment with intravenous minocycline (400 mg/day), heparin for D.I.C. and corticosteroid were started. Abnormal findings in both chest X-ray and several laboratory parameters improved gradually though fever continued for a week. On the 14th day of her hospital stay, she was weaned from the ventilator successfully and the administration of corticosteroid and heparin tapered. On the 41st day, she was discharged without any symptoms. Results of complement fixation (CF) antibodies against chlamydia on paired sera showed a significant rise from 1:32 to 1:256. Moreover, both IgG and IgM antibodies for Chlamydia psittaci with microplate immunofluorescent antibody technique (MFA) showed an 8 times' rise during 10 days after admission. The definitive diagnosis was made with positive isolation of C. psittaci from both the throat swab of this patient and the spleen and liver of the dead budgerigar by the cell culture method. Psittacosis should always be borne in mind as a possible cause of fulminant pneumonia with acute respiratory failure, and such a situation can be handled successfully if emergency care including mechanical ventilation is available.

Abstract
A stabilized modification of the single radial complement fixation test in gel (SRCF) was developed for detecting influenza antibodies. The principle of the test is the use of a single-step procedure with the following reagents: (1) Agarose plate containing influenza antigen and antibody coated erythrocytes (EA). (2) Thin plastic film coated with dried complement. By filling the wells cut in the agar with the heat inactivated serum samples and covering the agar surface with the complement film, a zone of unlysed cells surrounded by a haemolytic area appears after overnight incubation for 16-18 h at 4 degrees C and 1-2 h at 37 degrees C. The squares of the zone diameter were measured for estimating the antibody quantity by using CF(S) and virion antigen of influenza virus, and the type-specific antibody was demonstrated by using CF(S) antigen, while the strain-specific antibody was demonstrated by using virion antigen. An excellent correlation was demonstrated for antibody titres between conventional CF and SRCF with CF(S) antigen, on the one hand, and, between conventional HI and SRCF with virion antigen, on the other.(ABSTRACT TRUNCATED AT 250 WORDS)

High titre of antibody to hepatitis B core antigen detected by immune adherence haemagglutination in HBsAg-positive acute hepatitis. HEPATO-GASTROENTEROLOGY 1982; 29:142-3.

Abstract
Nine patients with HBsAg-positive acute hepatitis were tested for antibody to hepatitis B core antigen (anti-HBc) by the immune adherence haemagglutination method. A high anti-HBc titre (2(15) or more) was found in three, while anti-HBc was not detectable in the remaining six. All of them recovered from hepatitis with the return of hepatic function tests to normal, but HBsAg persisted in the three patients whose acute-phase serum had revealed high anti-HBc titres. On the basis of these observations, the three patients were thought to be persistent HBsAg carriers who had contracted opportunistic acute hepatitis of non-B aetiology. Titration of anti-HBc may be indicated in patients with HBsAg-positive acute hepatitis, because it helps distinguish persistent HBsAg carriers with non-B hepatitis from patients with hepatitis B at the outset, during the episode of acute hepatitis.
