This study is carried out to investigate the analysis of nutrition and antioxidants of soybean Chungkukjang powder (SCP), Yak-Kong Chungkukjang powder (YCP) and Yak-Kong Chungkukjang powder added black foods (YCBP) for the management of Alzheimer's disease. The water content of YCBP was higher than that of SCP and YCP. The soluble and crude protein contents of YCP were the highest among three Chungkukjang powders. In SCP, YCP and YCBP, the ratios of unsaturated and saturated fatty acids were 5.17, 5.76, and 5.78, respectively. The mineral content of SCP was higher than that of YCP and YCBP. Antioxidants analysis showed that the content of diadzein was the highest in YCP and genistein, and anthocyanin contents were higher than the others in YCBP. In conclusion, YCP and YCBP had higher contents than SCP in soluble and crude proteins, and unsaturated fatty acids, which are needed for composition and function of the brain tissue. Also, it was found that the contents of diadzein, genistein and anthocyanin with outstanding antioxidative ability were high. Thus, this study suggests that Chungkukjang powder, which is made with Yak-Kong, black sesame, black rice and sea tangle, can be utilized for in vivo experiment for the control of oxidative stress, reported as cause and therapy for Alzheimer's Disease.

Purpose: The purpose of this study was to review primary traumatic anterior shoulder dislocation in the 40 years and older to determine the incidence of recurrence, rotator cuff injury and associated fractures. Materials and Methods: From May, 1991 to October, 1998, seventeen patients were available to participate in the study. The average age was 55 years(range, 40 to 75 years). Follow-up averaged 27 months(range, 12 to 48 months). There were 12 men and 5 women. 10 right and 7 left shoulders were involved. Any participant with a history of shoulder pain and limitation of motion was excluded from the study. Each shoulder was evaluated with UCLA shoulder functional assessment. Results: The overall results were excellent in 9 patients(52.9%), good in 3 patients(17 .6%), fair in 3 patients(17.6%), and poor in 2 patients(11.7%). Surgical treatment of the associated rotator cuff and greater tuberosity fracture injuries resulted in 5 patients with excellent(55.6%), 3 patients with good(33.3%) and I patient with poor(11.1 %) and Nonsurgical treatment of the associated injuries resulted in 2 patients with excellent(33.3%), 3 patients with fair(50%), 1 patient with poor(16.7%)(P=0.025). Conclusion : Our findings on small number of patients suggest that the diagnosis of a rotator cuff and other pathologies should be approached aggressively by an MRI, CT arthrogram if significant pain and weakness are still present and early surgical repair of rotator cuff and greater tuberosity can lead to restoration of shoulder function and better outcomes in selected patients.

Sinus floor augmentation has been proven an effective treatment procedure to increase bone volume in the posterior edentulous maxilla. Autogenous bone considered to be the best material for reconstructive bone surgery and has been successfully used as a graft material to augment posterior maxilla. However, the collection of autogenous bone required extra risks for morbidity and complaints. So, various bone graft materials included ${\beta}$-tricalcium phosphate(${\beta}$-TCP) has been introduced for replacing the autogenous bone. The objective of this clinical study was to determine the predictability of endosseous implant placed in a maxillary sinus with ${\beta}$-TCP grafting. We performed sinus elevation with ${\beta}$-TCP to install the implant in the 10 maxillary cases. The prosthetic procedure was performed 6-9 months after. The implant-prosthetics was checked about 1 year. We checked the implant and measured the maximum bite force to evaluate the function of the implant. There was not observed the specific problem and complication in dental implant and maxillary sinus in the grafted materials. The maximum bite force was 558N in case of natural tooth, 365N in implant without grafting, 318N in implant with ${\beta}$-TCP grafting. There was no significant difference between with and without sinus grafting on maximum bite force(p>0.05). As though the long term check-up is needed, the grafting of ${\beta}$-TCP as a osteoconductive materials can expand the volume and induce dense new bone formation in maxillary sinus. So, this short-term results support that ${\beta}$-TCP can be a suitable material for sinus augmentation.

To elucidate the biochemical etiology. 1) plasma dopemine-beta-hydroxylase activity was measured and 2) the correlation between age and DBH activity was examined in 30 Tourette's disorder, 19 chronic motor tic disorder, and 24 controls. The results are summarized as follows : 1) The mean plasma DBH activity in Tourette's disorder was significantly elevated compared to normal groups, but significant differences in DBH activity between Tourette's disorder and chronic motor tic disorder, and between chronic motor tic disorder and normal control group were not found. 2) In all three groups, the significant positive correlations between age and plasma DBH activity found. These findings support the hypothesis of a possible involvement of brain catecholamine dysfunction in the production of Tourette's disorders, and this dysfunction might be due to the increased dopaminergic and decreased noradrenergic function. Future research should be focused on the mechanism of functional abnormalities of DBH.
It has been proposed that oxidative modification of LDL (oxLDL) plays a significant role in the pathogenicity of atherogenesis. We tested the hypothesis that chitin and chitosan may function as antioxidants with respect to 0.1 mg cholesterol/ml LDL incubated with 5 $\mu$ M Cu$^2$$^{+}$alone or in the P338Dl mouse macrophage system using L-ascorbic acid as a standard classical antioxidant. The degree of oxLDL formation was ascertained by the relative electrophoretic mobility (rEM) in the combination of thiobarbituric acid reactive substances (TBARS) levels, and the cytotoxicity of oxLDL was detected by macrophage viability. The oxLDL uptake and foam cell formation of macrophages were measured by Oil Red O staining. Incubation with Cu$^2$$^{+}$and macrophages increased rEM of LDL and stimulated TBARS formation. Culture of macrophages with LDL in the presence 5 $\mu$ M Cu$^2$$^{+}$induced macrophage death. In cell-free system 200 $\mu$g/ml water-soluble chitosan and chitosan-oligosaccharide blocked oxLDL formation. Water-soluble chitosan and chitosan-oligosaccharide blocked oxLDL formation near-completely relative to L-ascorbic acid, whereas water-soluble chitin and chitin-oligosaccharide had no measurable antioxidant effect. In macrophage system water-soluble chitosan and chitosan-oligosaccharide blocked oxidation of LDL with a significant increase in cell viability, and decreased TBARS in medium. As for the inhibitory effect on macrophage foam cell formation, chitosan and its oligosaccharide, but not watersoluble chitin, revealed the effectiveness. The endothelial expression of lectin-like oxLDL receptor-1 (LOX-1) was tested by Western blot analysis, and chitosan, chitosan-oligosaccharide and chitin-oligosaccharide blocked LOX-1 expression. These results indicate that water-soluble chitosan and its oligosaccharide showed the inhibitory effect on Cu$^2$$^{+}$-induced LDL oxidation of macrophages, and chitosan, chitosan-oligosaccharide and chitin-oligosaccharide had blocking effect on oxLDL receptor expression in the human umbilical vein endothelial system. Thus, water-soluble chitosan and its oligosaccharides possess anti-atherogenic potentials possibly through the inhibition of macrophage LDL oxidation or endothelial oxLDL receptor expression depending on chemical types.l types.
Objectives : Since ancient times, Koreans have applied medicinal spabaths for treatment of various diseases. The objective of this study was to investigate the effect of strontium, one of the common ingredients of such baths, experimentally on acute skin barrier damage. Materials and Methods : Male hairless mice, average weight 20g, were divided into six groups. Each group consisted of five mice. The first was the normal, non-treated group. The second was the control group with acute skin barrier damage intentionally induced by TS. The third was the Ba-Sr1 group bathed in 1mg/L strontium chloride before and after inducing acute skin barrier damage by TS. The fourth was the Ba-Sr7 group bathed in 7mg/L strontium chloride before and after inducing acute skin barrier damage by TS. The fifth was the Sr1 group bathed in 1mg/L of strontium chloride only after intentionally inducing acute skin barrier damage by TS. The sixth was the Sr7 group bathed in 7mg/L of strontium chloride only after intentionally inducing acute skin barrier damage by TS. External changes of skin, skin erythema level, transepidermal water loss level, and GOT and GPT level of each group were checked immediately before and after TS, 3 hrs, 5 hrs and 24 hrs after inducing acute skin barrier damage. Then, tissue samples were made and examined for damage to epithelial cells, stratum corneum, change of mucous polysaccharide in dermis and amount of mast cells. Statistical analysis was performed by one way-ANOVA, Scheffe and Duncan for a post hoc test and pairwise comparison for comparing for difference between each time. Statistical significance was achieved if the probability was less than 5% (p<0.05) Results : 1. From skin erythema and TEWL level indicating the function of the skin barrier, we can know that it is helpful to the skin barrier to bathe in a water solution including a low concentration of strontium. 2. In the control group with acute skin barrier damage induced by TS, skin barrier damage persisted until 3-5 hrs and recovered after 5-24 hrs. Differently from the control group, in the case of taking a bath in a water solution including strontium, skin barrier damage recovered after only 3-5 hrs. Therefore, the bath with a water solution including strontium can promote recovery of the skin barrier. 3. Bathing in water solution including a higher concentration of strontium was more beneficial to recovery of skin barrier damage. 4. There was no influence on serum GOT and GPT from bathing in a water solution including strontium. Conclusions : The strontium was effective for recovery and mitigation of acute skin barrier damage induced by tape stripping. I suggest that strontium (Sr) can be used as an external treatment medicine, addedinto bath water to treat acute skin barrier damage.
Purpose: Fatty liver is one of the most commonly found disease by abdominal ultrasonography. The status of fatty liver is classified into mild, moderate and severe degrees. The study was conducted to investigate the clinical significance of fatty liver using ultrasonography. Materials and method: Test set consisted of 2,185 patients who visited D healthcare center in Daejeon to receive an abdominal ultrasonic test from January to December 2007. Out of the 2185 patients, 524 patients was diagnosed as fatty liver (290 male and 234 female patients). They were divided into three groups, group I for mild degree. II for moderate degree, and III for severe degree, depending on the echo of liver parenchyma, the sound attenuation, and the visibility of intrahepatic blood vessels and diaphragm. Then the correlation of obesity indices, liver function tests and metabolic syndrome was analyzed for males and females separately. Results : As for the degree of fatty liver, 350 cases (66.8%) were classified as group I, 153 cases (29.2%) as group II, and 21 cases (4.1%) as group III. In addition, severe degree of fatty liver was more frequently found in males than in females. The mean ages of three groups for males were 46.1, 44.5, and 39.1, and those for females were 48.8, 50.2, 52.4, respectively. Males with lower mean ages have severely of fatty liver for both males and females. Conclusion: The results in this study show that the classification into three degrees of fatty liver in ultrasonography practice is helpful to treat and observe the progress of fatty liver. In addition, careful examination is required to measure the severity of fatty liver as well as detection of it. A standardized method to classify the degree of fatty liver is also needed for more objective measurement.
Both high glucose and glucose degradation products (GDP) have been implicated in alterations of peritoneal membrane structure and function during long-term peritoneal dialysis (PD). The present study examined the role of GDP including methylglyoxal (MGO), acetaldehyde, and 3,4-dideoxyglucosone (3,4-DGE) in HPMC activation with respect to membrane hyperpermeability or fibrosis. The role of reactive oxygen species (ROS) and activation of protein kinase C (PKC) in GDP-induced HPMC activation were also examined. Using M199 culture medium as control, growth arrested and synchronized HPMC were continuously stimulated by MGO, acetaldehyde, and 3,4-DGE for 48 hours. Vascular endothelial growth factor (VEGF) was quantified as a marker of peritoneal membrane hyperpermeability and fibronectin and heat shock protein 47 (hsp47) as markers of fibrosis. Involvement of ROS and PKC was examined by the inhibitory effect of N-acetylcystein (NAC) or calphostin C, respectively. MGO significantly increased VEGF (1.9-fold), fibronectin (1.5-fold), and hsp47 (1.3-fold) secretion compared with control M199. NAC and calphostin C effectively inhibited MGO-induced VEGF upregulation. Acetaldehyde stimulated and 3,4-DGE inhibited VEGF secretion. Fibronectin secretion and hsp47 expression in HPMC were not affected by acetaldehyde or 3,4-DGE In conclusion, MGO upregulated VEGF and fibronectin secretion and hsp47 expression in HPMC, and PKC as well as ROS mediate MGO-induced VEGF secretion by HPMC. This implies that PKC activation and ROS generation by GDP may constitute important signals for activation of HPMC leading to progressive membrane hyperpermeability and accumulation of extracellular matrix and eventual peritoneal fibrosis.

Mesenchymal stem cells (MSCs) are multipotent stem cells that can be differentiated into a variety of cell types, including adipocytes, osteoblasts, chondrocytes, β-pancreatic islet cells, and neuronal cells. MSCs have been reported to exhibit immunomodulatory effects in many diseases. Many studies have reported that MSCs have distinct roles in modulating inflammatory and immune responses by releasing bioactive molecules. Exosomes are cell-derived vesicles present in biological fluids, including the blood, urine, and cultured medium of cell cultures. In this study, we investigated the immunomodulatory effects of mouse adipose tissue-derived MSCs (mAD-MSCs), cultured medium (MSC-CM) of mAD-MSCs, and mAD-MSC-derived exosomes (MSC-Exo) on lipopolysaccharide (LPS)-induced RAW 264.7 cells. We observed that the expression levels of IL-1β, TNF-α, and IL-10 were significantly increased in LPS-stimulated RAW 264.7 cells compared to those in LPS-unstimulated RAW 264.7 cells. Additionally, these values were significantly (p < 0.05) decreased in mAD-MSCs-RAW 264.7 cell co-culture groups, MSC-CM-treated groups, and MSC-Exo-treated groups. MSCs can modulate the immune system in part by secreting cytokines and growth factors. We observed that immunomodulatory factors such as IL-1β, TNF-α, and IL-10 were secreted by mAD-MSCs under co-culturing conditions of mAD-MSCs with activated RAW 264.7 cells. In addition, mAD-MSC-derived exosomes exhibited similar immunomodulatory effects in activated RAW 264.7 cells. Therefore, our results suggest that mAD-MSCs have an immunomodulatory function through indirect contact.

An experiment was carried out to study plasma levels of hormones and metabolites of crossbred Holstein cattle during late pregnancy (28 days pre partum), early lactation (30 days post partum), mid-lactation (120 days post partum) and late lactation (210 days post partum). Two breed types of Holstein $Friesian{\times}Red$ Sindhi (50:50 = 50%HF) and Holstein $Friesian{\times}Red$ Sindhi (87.5:12.5 = 87.5%HF) were divided into four groups of four animals each. Two groups of each breed were fed with either rice straw treated with 5% urea or pangola hay (Digitaria decumbens) as the source of roughage throughout the experiments. There were a substantial increases in the mean levels of total triiodothyronine ($T_3$), insulin and glucagon at the onset of lactation, and maintained in a high levels during lactation advance for all groups of experiments. The mean levels of prolactin and thyroxine ($T_4$) were not significantly different among groups of animals, but the plasma cortisol concentration was slightly higher in both groups of 50%HF in comparison with those of 87.5%HF animals. The mean levels of plasma growth hormone (GH) of both groups of 87.5%HF animals feeding on either hay or urea treated rice straw markedly rose in the early period of lactation and markedly reduced in mid- and late lactation. These changes were accompanied with changes of milk yield. In contrast to 50%HF animals, plasma GH levels were considerably higher in the late pregnant period than in the early period of lactation and it remained constant as its value at the early lactation throughout the experimental period. The high levels of both plasma progesterone and estradiol concentration significantly declined after parturition and remained low through lactating period. The plasma glucose level in the 50%HF animals feeding on either hay or urea treated rice straw was higher than the 87.5%HF animals in all periods of experiments. Changes in plasma FFA levels of both types of crossbred animals were depended on the endocrine status during late pregnancy and lactation. The levels of plasma FFA of 50%HF animals were significantly higher (p<0.05) than those of 87.5%HF animals during late pregnancy. Both plasma ${\beta}$-hydroxybutyrate and lactate concentrations were not affected by feeding on either hay or urea treated rice straw during late pregnancy and lactation. These data demonstrate that there were no differences in the physiological performances in the same crossbred animals fed either hay or urea treated rice straw. The 87.5%HF animal has the genetic potential for a high milk yield and homeorhetic adaptation for mammary function differed from 50%HF animals during periods of lactation. Altering lactation persistency in 87.5%HF is regulated mainly by chronically acting growth hormones through the period of lactation.
