  • The influence of selenuium deficiency and fish oil on lipid peoxidation status and fatty acid composition of tissues(plasma aorta and liver) was studied. Male Sprague Dawley rats were fed for eight weeks semipurified diets containing 7% corn oil(by weight) or 5, 5% fish oil(MaxEPA) plus 1.5% corn oil with oil with or without selenium status (glutathione peroxidase activity and selenium levels) were significantly lower in the rats given inadequate selenium in plasma aorta (p<0.02 and p<0.001 respectively) gut not that in plasma Selenium supplementation decreased hepatic MDA levels(p<0.02) Increases in the levels of 20:5(n-3) 22:5(n-3), 22:6(n-3) 20:3(n-6) and a decrease in the level of 20:4(n-6) were observed in plasma total lipids and aortic and hepatic phospholipids when fish oil was fed. Though selenium supplementation increased the level of n-3 fatty acids(such as 22:6(n-3)) in plsama and the aorta is overall effect was smaller than the effect of fish oil feeding. These data suggest that selenium may play a significant but minor role in protecting against lipid peroxide-tion even when vitamin E intakes are in excess of current recommendations in both corn oil and fish oil diets.

  • Purpose: Recently, complementary and alternative medicine (CAM) has been increasingly used in children. Studies have shown that 34% of adults and 11% of children use CAM in the USA and Canada. The purpose of this study was to investigate the prevalence and patterns of CAM use in elementary children in Korea. Methods:From July to August 2007, parents of elementary children completed a questionnaire survey at Gwang-ju. In all, 794 questionnaires were analyzed. Results:Of the 794 respondents, 278 answered that their pupils (35%) had experienced CAM. The following types of CAM therapy were used: herbal medicine, 62.5% dietary supplements, 31.2% vitamins, 30.2% and acupuncture, 11.1%. CAM therapies were used for the following diseases: nutritional deficiency, 33.3% atopic dermatitis, 31.3% arthralgia, 31.3% allergic rhinitis, 28.8% obesity, 26.3% and asthma. The following were the motives to use CAM: prevention of diseases (33.5%), dissatisfaction with modern medicine (21.2%), and complementary therapy to modern medicine (20.5%). People gained information about CAM through neighbors (65%) and mass media (21%). Moreover, 83 parents (30%) were satisfied with CAM because of its effectiveness. Conclusion:Many parents have advocated the use of CAM in their children. However, most of them used CAM without any prescription or adequate knowledge. Further studies are required to determine the efficacy of CAM.

  • The immune system protects the body against harmful substances and infectious agents. Normally, the body can maintain a state of immune homeostasis. However, failure of immune homeostasis results in severe diseases when the immune system is defective. We investigated the immunomodulatory effect of Curcuma longa L. extract in LP-BM5 MuLV (murine leukemia viruses)-induced murine AIDS (acquired immune deficiency syndrome). Mice were divided into six groups: normal control, infected control (LP-BM5 MuLV infection), positive control (LP-BM5 MuLV infection+dietary supplement of red ginseng 200 mg/kg), CL50 (LP-BM5 MuLV infection+dietary supplement of Curcuma longa L. 20% alcohol extract 50 mg/kg), CL200 (LP-BM5 MuLV infection+dietary supplement of Curcuma longa L. 20% alcohol extract 200 mg/kg), and CL500 (LP-BM5 MuLV infection+dietary supplement of Curcuma longa L. 20% alcohol extract 500 mg/kg). We found that dietary supplementation with Curcuma longa L. 20% alcohol extract inhibited elevation of spleen, lymph node, and liver weights as well as reduction of T- and B-cell proliferation and natural killer cell activity induced by LP-BM5 MuLV infection. Moreover, Curcuma longa L. 20% alcohol extract inhibited Th1 (IL-2, IFN-${\gamma}$)/Th2 (IL-4, IL-10) cytokine imbalance and pro-inflammatory cytokine production. In conclusion, these data suggest that Curcuma longa L. has immunomodulatory effects in LP-BM5 MuLV-induced murine AIDS.

  • Chromium has been known to be involved in the glucose metabolism, and hence the utilization of cellular glucose is impaired in the chromium deficiency. Chromium has been recognized as an essential nutrient since the finding of low-molecular-weight Cr-binding substance (LMWCr) as a biological modifier of insulin action. Clinical chromium deficiency associated with glucose intolerance that respond to the administration of chromium. The major impediment to the use of orally administered chromium is poor absorption of trivalent chromium in its inorganic form. Trivalent chromium is more available in yeast md, more recently, as chromium picolinate for oral absorption. The widespread use of these supplements has resulted in controversy regarding chromium's role as a nutrient, its use for treatment of insulin resistance, and its potential toxicity. Most recent evidence strongly supports tile conclusion that there is little fear of toxic reactions from chromium consumption. This report reviews the evidence for the potential toxicity of chromium supplements in contrast with its usefulness as a nutrient or therapeutic agent in the treatment or prevention of insulin resistance.

  • Based on the soft and rigid extents, tissues are mainly divided into two groups in mammals, soft tissues including heart, lung, kidney and brain, and hard tissues including tendon, cartilage, teeth and bone. Among various tissues, bone, a dynamic rigid organ, is continuously remodeled by the opposing functional activity between bone formation by osteoblasts and bone destruction by osteoclasts. Bone protects the soft tissues and provides mineral reservoirs, which can supply the mineral needs of other soft tissues to normally maintain cellular function. While calcification in bone is an important action to fundamentally support the body and protect the soft tissues, calcification in soft tissues, including the heart, aorta, kidney, lung and spleen, results in severe organ damages, eventually causing sudden death. A growing body of evidence indicates that the osteoporotic patient who are aging, post-menopausal, diabetes and chronic kidney disease simultaneously represent a high clinical incidence of soft tissue calcification, illustrating a link between soft tissue calcification and bone decalcification (osteoporosis). This study will review what is currently known about the connection between bone decalcification and soft tissue calcification.

  • Delirium is among the most common mental disorders encountered in patients with a temporary cognitive impairment such as consciousness disorder, attention disorder, and poor speech, particularly among those who are older. Delirium is distressing for patients and families, can interfere with the management of symptoms such as pain, and is associated with increased elderly mortality. The purpose of this paper is to generate useful clinical knowledge that can be used to distinguish the outcomes of patients with delirium in long-term care facilities. For this purpose, we extracted the clinical classification knowledge associated with delirium using a local covering rule acquisition approach with the rough lower approximation region. The clinical applicability of the proposed method was verified using data collected from a prospective cohort study. From the results of this study, we found six useful clinical pieces of evidence that the duration of delirium could more than 12 days. Also, we confirmed eight factors such as BMI, Charlson Comorbidity Index, hospitalization path, nutrition deficiency, infection, sleep disturbance, bed scores, and diaper use are important in distinguishing the outcomes of delirium patients. The classification performance of the proposed method was verified by comparison with three benchmarking models, ANN, SVM with RBF kernel, and Random Forest, using a statistical five-fold cross-validation method. The proposed method showed an improved average performance of 0.6% and 2.7% in both accuracy and AUC criteria when compared with the SVM model with the highest classification performance of the three models respectively.

  • Drought stress has detrimental effects on the seedling development, vegetative/ reproductive growth, photosynthesis, root proliferation, anthesis, anthesis-silking interval (ASI), pollination and grain yield in maize. Typically, two weeks before silking through pollination are an important time in maize life. Here we reviewed the effects of drought stress on growth, physiological/ molecular researches for drought tolerance, and breeding to genomics in maize. Drought stress during kernel development increases leaf dying and lodging, decreases grain filling period and grain yield. Physiological factors of drought stress/ effects are water content, water deficits, and water potential. Nowdays molecular marker assisted breeding method is becoming increasingly useful in the improvement of new germplasm with drought stress tolerance.

  • Osteomyelitis means inflammation of the bone marrow. It usually begins in the medullary cavity, involving the cancellous bone; then it extends and spreads to the cortical bone and eventually to the periosteum. The cause is usually thought to be microbiological. But there still are factors that predispose to produce a possible bone infection such as injuries, syphilis, actionomycosis, chronic kidney failure, alcoholism, malnutrition, radiotherapy, and chemotherapy. Treatment of modalities have been directed toward eradicating microbes and improving circulation in the early stage. In the case presented, surgical debridement and IV antibiotics were the treatment of choice. Osteomyelitis in children is mainly affected in the mandible. And in childhood, the mandibular condyle is regarded as an important center of mandibular growth. Therefore, in young patients, osteomyelitis involving this region may cause a restraint of mandibular development, resulting in facial asymmetry. So diagnosis in the early stage is important in child with osteomyelitis. Recently, we have encountered an interesting case of osteomyelitis of the mandibular condyle in 9-year-old boy. So we present the case and review the literature about osteomyelitis.

  • This study was conducted to research the industrial utilizaion of the maize germs separated in the manufacture of the cornstarch. The maize germs contained crude protein (25.3%) and crude fat (19.2%), with the 512 Kcal/100g of determined food energy values. It was found to have the valuable amounts of essential minerals, such as the content of calcium and phosphorus were low (53.0, 12.3mg%), while those of potassium (495.4mg%), magnesium (95.0mg%), zinc (48.3ppm) and manganese (45.2ppm) were plentiful. It was noted that the iodine value was 44.0, saponification value 292.3, acid value 1.5 and peroxide value about 3.3. The lipid fractions obtained by silicic acid column chromatography were mainly composed of neutral lipid, whereas, the contents of glycolipid and phospholipid were scarcely. The major fatty acids in total lipids were linoleic $(60{\sim}62.5%)$, oleic $(20{\sim}22.5%)$ and palmitic $(10{\sim}13.5%)$ acids. The content of the unsaturated fatty acids was more predominant than that of the saturated fatty acids. The content of the insoluble proteinous nitrogen (32.5%) was the most abundant. whereas, the contents of soluble proteinous nitrogen (12.7%) and peptide proteinous nitrogen (3.3%) were low. The major amino acids of the maized germs were glutamic, glycine, alanine and aspartic. It has been identified by the SDS-disc electrophoresis that the protein of maized germs had $5{\sim}6$ bands. Compared with standard substances, the molecular weight of the main protein was estimated to be $14,500{\sim}24,500$.

  • Burning mouth syndrome (BMS) is defined as burning pain in the tongue or other oral mucous membrane associated with normal sign and laboratory findings at least 4 to 6 months. There are many factors that affect this condition and the pain characters are various among the sufferers, so it is difficult to diagnose exactly and treat properly. The cause of BMS is currently unknown. The etiology is presumed to be that it is related with local, systemic and psychogenic factor. The BMS is related with local factor such as allergic reaction, oral fungal infection(candidiasis), parafunctional oral habits and systemic factors such as diabetes mellitus, hypothyroidism, nutritional deficiencies(vitamin $B_{12}$, folic acid), hyposalivation and psychogenic factor such as depression, anxiety, cancerphobia. So clinicians must be aware of these factors and can give proper treatment options to patients. The management of BMS are pharmacologic management, cognitive behavioral therapy and psychotherapy treatment. Clonazepam, gabapentin, amitriptyline, alpha-lipoic acid and capsaicin are used to manage the BMS. Among these, topical clonazepam is reported that the effect is higher than systemic medication and the complications are rare. This case report is about some cases of the effect of topical clonazepam on BMS.
