  • Pneumonia is infection of air sacs in lungs by bacteria, viruses, fungi and abnormal atmosphere condition. That causes to inflammation and fills up with pus and fulid in air sacs. The symptoms of pneumonia are heavy cough, fever, shortness and rapid respiration and sputum with blood. Also, that remains sequela after the recovery. Thymus quinquecostatus (TQ) has a strong antibacterial effect. That has been used a natural medicine for bronchitis, asthma and nervous inflammation. In this study evaluated anti-inflammatory effects of TQ on IFN (interferon)-γ/TNF (tumor necrosis factor)-α (20 ng/ml) stimulation. MRC-5 cells were seeded at 1 × 105 cells/well in a 24-well plate and stabilized overnight at 37℃. The cells were treated with various concentrations of TQ extracts (DW, 30, 50, 70, 95% EtOH, 0.1~100 mg/ml) for 4h, Subsequently IFN-γ/TNF-α (20 ng/ml) was added to each well and incubated over 12h. the production of inflammatory cytokines were measured by Enzyme-linked immunosorbentassay(ELISA) method. The absorbance was measured at 450 nm using microplate reader. The treatment with TQ extract at dose of 0.1 to 100 mg/ml did not show cytotoxicity in MRC-5 cells (showed cytotoxicity at 95% EtOH 100 mg/ml). The results demonstrated that stimulation of TNF-α/IFN-γ significantly increased the production of inflammatory mediators in the MRC-5 cells compared with unstimulated cells. By contrast, treatment with TQ extreats doses of 0.001 to 10 mM significantly suppressed the production of IL-6 and IL-8. Especially. The higher percent of ethyl alcohol extracts suppressed the production of inflammatory cytokines. This results are considered that essential oil of TQ is extracted according to ethyl alcohol percent. Therefore, TQ has potential to mitigate pulmonary disease that can be used a medicine for pneumonia

  • Objective: The objective of the current study was to find out the independent and interactive effects of prilled fat supplementation with protein on the production performance of early lactating Nili Ravi buffaloes. Methods: Sixteen early lactating buffaloes (36.75±5.79 d in milk; mean±standard error) received 4 treatments in 4×4 Latin-square design according to 2×2 factorial arrangements. The dietary treatments were: i) low protein low fat, ii) low protein high fat, iii) high protein low fat, and iv) high protein high fat. The dietary treatments contained 2 protein (8.7% and 11.7% crude protein) and fat levels (2.6% and 4.6% ether extract) on a dry matter basis. Results: The yields of milk and fat increased with increasing protein and fat independently (p≤0.05). Energy-, protein-, and fat-corrected milk yields also increased with increasing protein and fat independently (p≤0.05). Increasing dietary protein increased the protein yield by 3.75% and lactose yield by 3.15% and increasing dietary fat supplies increased the fat contents by 3.93% (p≤0.05). Milk yield and fat-corrected milk to dry matter intake ratios were increased at high protein and high fat levels (p≤0.05). Milk nitrogen efficiency was unaffected by dietary fat (p>0.10), whereas it decreased with increasing protein supplies (p≤0.05). Plasma urea nitrogen and cholesterol were increased by increasing protein and fat levels, respectively (p≤0.05). The values of predicted methane production reduced with increasing dietary protein and fat. Conclusion: It is concluded that prilled fat and protein supplies increased milk and fat yield along with increased ratios of milk yield and fat-corrected milk yields to dry matter intake. However, no interaction was observed between prilled fat and protein supplementation for production parameters, body weight, body condition score and blood metabolites. Predicted methane production decreased with increasing protein and fat levels.

  • Elaeocarpus sylvestris var. ellipticus is an evergreen tree of the family Elaeocarpaceae, which is a plant that grows naturally only in subtropical regions due to its vulnerability to cold. E. sylvestris has been reported to have flavonoids, coumarins, and polyphenols, and it is reported that these components have antibacterial and antioxidant effects. In this study, a roasting technique was introduced to increase the physiological activity of E. sylvestris, and antioxidant, total phenol, and total flavonoid content were measured after confirming changes in the ingredients of roasted E. sylvestris extracts and fractions. We analyzed the extracts before and after roasting and found an increase in the content of four components (brevifolin, ellagic acid, quercetin, and kaempferol), with the roasted extracts showing better antioxidant activity. The optimal roasting condition was confirmed to have the best antioxidant effect when roasting at 200 ℃ for 30 min, and the total phenol and total flavonoid content were also confirmed to be the best. E. sylvestris extract produced under optimal roasting conditions has been confirmed to exhibit improved antioxidant effects, and it is believed that it can be used as a cosmetic and food material in the future.

  • Muscle atrophy, which is defined as a decrease in muscle mass and strength, is caused by an imbalance between the anabolism and catabolism of muscle proteins. Thus, modulating the homeostasis between muscle protein synthesis and degradation represents an efficient treatment approach for this condition. In the present study, the protective effects against muscle atrophy of ethanol extracts of Morus alba L. (MA) and Angelica keiskei Koidz. (AK) leaves and their mixtures (MIX) were evaluated in vitro and in vivo. Our results showed that MIX increased 5-aminoimidazole-4-carboxamide ribonucleotide-induced C2C12 myotube thinning, and enhanced soleus and gastrocnemius muscle thickness compared to each extract alone in dexamethasone-induced muscle atrophy Sprague Dawley rats. In addition, although MA and AK substantially improved grip strength and histological changes for dexamethasone-induced muscle atrophy in vivo, the efficacy was superior in the MIX-treated group. Moreover, MIX further increased the expression levels of myogenic factors (MyoD and myogenin) and decreased the expression levels of E3 ubiquitin ligases (atrogin-1 and muscle-specific RING finger protein-1) in vitro and in vivo compared to the MA- and AK-alone treatment groups. Furthermore, MIX increased the levels of phosphorylated phosphoinositide 3-kinase (PI3K), protein kinase B (Akt), and mammalian target of rapamycin (mTOR) that were reduced by dexamethasone, and downregulated the expression of forkhead box O3 (FoxO3a) induced by dexamethasone. These results suggest that MIX has a protective effect against muscle atrophy by enhancing muscle protein anabolism through the activation of the PI3K/Akt/mTOR signaling pathway and attenuating catabolism through the inhibition of FoxO3a.

  • Purpose: Type 2 diabetes mellitus is a metabolic condition marked by persistent elevated blood sugar levels resulting from insulin resistance. The effective management of diabetes mellitus involves strict regulation of the blood glucose levels. This study examined the effects of Autumn olive (Elaeagnus umbellata Thunb.) berry (AOB) on insulin resistance and hyperglycemia using a type 2 diabetes mellitus animal model. Methods: Eight-week-old C57BL/6J mice were divided into four groups. The control group received a basal diet, while the high-fat, high-sucrose (HFHS) group was fed a HFHS diet containing 27% sucrose and 33% lard for 12 weeks. The low AOB (LAOB) and high AOB (HAOB) groups were offered a HFHS diet with a 0.5% and 1.0% AOB extract, respectively. Results: The HAOB group showed significantly lower epididymal fat pad weight than the HFHS group. The LAOB and HAOB groups showed lower serum glucose levels and homeostasis model assessment for insulin resistance values than the HFHS group, and the HAOB group has lower serum insulin levels than the HFHS group. Supplementation with HAOB decreased serum cholesterol levels significantly compared with the HFHS group. The consumption of LAOB and HAOB reduced the serum triglyceride and hepatic total lipids and triglyceride levels compared to the HFHS group. In addition, LAOB and HAOB consumption in mice fed a HFHS diet increased adenosine monophosphate-activated protein kinase protein expression. Insulin receptor substrate-2 protein expression in the HAOB group was significantly higher than the HFHS group. Conclusion: AOB can alleviate hyperglycemia in type 2 diabetes mellitus partly by mitigating insulin resistance.

  • Wild grapes contain lots of organic acids, vitamins and inorganic salts compared to other fruits. Also, it has known to have excellent effects on preventing cancer and heart disease. Wild grapes are supposed to be superior material for fermentation of wine. Tannin contents of wine, which is an important functional factor in flavor of wine, were enhanced to develop quality of Korean wild grape wine. In this study, we investigated tannin extraction conditions and analyzed quality properties of tannin-enhanced wild grape wine. The most suitable tannin extraction condition for enhancing tannin of wild grape wine was extraction of tannin from green tea using spirits at 4oC. For producing high quality wild grape wine, added concentration and time of tannin extract were 6.5 mg/mL before wild grape wine fermentation. Tannin contents of tannin-enhanced wild grape wine was $7.4{\pm}0.05\;mg/mL$. Quality properties of tannin-enhanced wild grape wine fermented under optimized fermentation conditions were analyzed. pH, acidity and alcohol contents were $3.69{\pm}0.01$, $0.95{\pm}0.01%$ and $12.2{\pm}0.03%$, respectively. Total sugar, tannin, polyphenol and resveratrol contents of tannin-enhanced wild grape wine were $60.00{\pm}1.15\;mg/mL$, $79.50{\pm}0.55\;mg/mL$, $7.40{\pm}0.05\;mg/mL$ and $5.00{\pm}0.11\;mg/mL$, respectively showing significantly higher value than that of commercial wine. Production of high quality wild grape wine is expected with the establishment of optimum fermentation condition and tannin-enhancing process of wild grape wine.

  • Objectives . This study was conducted in order to investigate the degree of recognition, acceptability, and altitude towards day surgery of patients who were hospitalized with diseases that were candidates for day surgery; in order to analyze the average length of stay for treatment of the ailments; and to analyze the percentage of patients who could be discharged on the same day after the surgery ,using the post-anesthesia discharge scoring system. Methods : Data was collected between February 1 and March 31, 1999 from 353 patients who received surgery for cataract, adenoid hypertrophy, inguinal hernia, strabismus, ptosis, cholelithiasis, hemorrhoid, or anal fistula, at a general hospital in Daegu city. The patients were interviewed and surveyed by a post-anesthesia discharge scoring system(PADS) in order to collect data on patient condition such as vital signs, activity and mental status, pain, nausea and vomiting, surgical bleeding, intake and output after the surgery. Results : Among the 353 patients, 52.7% were after of the day surgery and 52.7% were interested in day surgery. Of the respondents, 43.1% said 'my ailment was not serious and the surgery was simple' and 30.4% said 'according to my condition rest at home was desirable' as the reasons for wanting day surgery Alternatively, 56.5% of those declining day surgery said the 'uncertainty of staying home' was the reason. The greatest concern in discharging within 24 hours after surgery was a post-op emergency situation. On the other hand, the shortened hospitalization was the largest advantage of day surgery with 39.1% responding this way, followed by the savings in hospitalization costs (25.8%) and emotional stability (13.7%). The majority of those surveyed (47.6%) believed that discharge should be determined within 1-2 days after the surgery. The average hospital stay was 3.1 days for dischargeable ailments. Pain (45.6%), nausea and vomiting (10.5%), and headache (7.9%) were the common symptoms following surgery. The percentage of patients who were able to be discharged within 24 hours after surgery revealed 95.2% were dischargeable after approximately 3 hours, 99.2% dischargeable after 12 hours, and 100% dischargeable after 24 hours. Conclusions : According to the PADS score, the cataract extract and strabismus correction patients were eligible for day surgery and the further evaluation concerning the reason for delayed recovery of the other diseases is needed.

  • To investigate whether the introduced genetic marker is useful to detect the survivalship and activity of the natural bacteria under the stressed conditions, one Gram-negative isolate, KP964 was transformed to the luminous phenotype by transferring luxAB gene. Under the starvation-stress this luminous bacterial culturability (determined by colony-forming-units [CFU] on agar plate) decreased rapidly below the detection limit by 37 days, while its total cell number (determined by AODC) remained almost the same as its initial inocular size. At that time period, the viable cell number was estimated to be 1400 times higher than its CFU number. The bioiuminescence (determined by relative light units [RLU]) produced under the same condition was also monitored and found to decrease more rapidly than the culturability by 5-fold. Under the other stresses, e.g., osmotic shocks, acid shock, and exposure to toxic chemicals, this bacterial strain did not show the reliable correlation between CFU and RLU. These results might not suggest the direct estimation of bioiuminescence from the stressed bacteria be an index of both the survivalship and its activity. However, when the stressed bacterial cells were incubated under the favorable condition by relieving from the existing stress, the potential bioiuminescence (the lag periods before the increase of bioiuminescence, the increase rates of bioiuminescence, and the maximal levels of bioiuminescence) was shown to be highly dependent upon the strengths of the stresses exposed to the bacterial cells. Therefore, analysis of the potential bioiuminescence from the stressed bacteria revealed good relationships with survival as well as activity.

  • In crime scene investigation, fingerprint identification is regarded to be one of the most important techniques for personal identification. However, objective and unbiased evaluation methods that would compare the fingerprints with diverse available and developing methods are currently lacking. To develop an objective and quantitative method to improve fingerprint evaluation, a preliminary study was performed to extract useful research information from the analysis with densitometric image analysis (CP Atlas 2.0) and the Automated Fingerprint Identification System (AFIS) for the developed fingerprints on porous surfaces. First, inked fingerprints obtained by varying pressure (kg.f) and pressing time (sec.) to find optimal conditions for obtaining fingerprint samples were analyzed, because they could provide fingerprints of a relatively uniform quality. The extracted number of minutiae from the analysis with AFIS was compared with the calculated areas of friction ridge peaks from the image analysis. Inked fingerprints with a pressing pressure of 1.0 kg.f for 5 seconds provided the most visually clear fingerprints, the highest number of minutiae points, and the largest average area of the peaks of the friction ridge. In addition, the images of the developed latent fingerprints on thermal paper with the iodine fuming method were analyzed. Fingerprinting condition of 1.0 kg.f/5 sec was also found to be optimal when generating highest minutiae number and the largest average area of peaks of ridges. Additionally, when the concentration of ninhydrin solution (0.5 % vs. 5 %) was used to compare the developed latent fingerprints on print paper, the best fingerprinting condition was 2.0 kg.f/5 sec and 5 % of ninhydrin concentration. It was confirmed that the larger the average area of the peaks generated by the image analysis, the higher the number of minutiae points was found. With additional tests for fingerprint evaluation using the densitometric image analysis, this method can prove to be a new quantitative and objective assessment method for fingerprint development.

  • Fracture about proximal humerus may be classified as the articular segment or the anatomical neck, the greater tuberosity, the lesser tuberosity, and the shaft or surgical neck. Now, usually used, Neer's classification is based on the number of segments displaced, over 1cm of displaced or more than 45 degrees of angulation , rather than the number of fracture line . Absolute indication of a operative treatment a open fracture, the fracture with vascular injury or nerve injury , and unreductable fracture-dislocation . Inversely, the case that are severe osteoporosis, and eldly patient who can't be operated by strong internal fixation is better than arthroplasty used by primary prosthetic replacement and early rehabilitation program than open reduction and internal fixation. The operator make a decision for the patient who should be taken the open reduction and internal fixation, because it's different that anatomical morphology, bone density, condition of patient. The operator decide operation procedure. For example, percutaneous pinning, open reduction, plate & screws, wire tension bands combined with some intramedullary device are operation procedure that operator can decide . The poor health condition for other health problem, fracture with unstable vital sign and severe osteoporosis , are the relative contraindication. The stable fracture without dislocation is not the operative indication . The radiologic film of the prokimal humerus before the operation can not predict for fracture evaluation. It's necessary to good radiologic film for evaluation of fracture form. The trauma serise is better than the other radiologic film for evaluation. The accessary radiologic exam is able to help for evaluation of bone fragment and anatomy. The CT can be helpful in evaluating these injury, especially if the extract fracture type cannot be determined from plain roenterogram of the proximal humerus, bone of humerus head. If the dislocation is severe anatomically , we could consider to do three dimentional remodelling. The MRI doing for observing of bony morphology before the operation is not better than CT If we were suspicious of vascular injury, we could consider the angiography.
