This experimental study was carried out to evaluate the effects of Kimchi intake of Acanthopanacis cortex extract (APCE) supplementation on cytokine-induction and immune response in mice. To study in experiments using male Balb/c mice fed Kimchi and Kimchi of APCE supplementation (addition of 2% of total Kimchi weight) containing fed experimental diet during 2 weeks. Experimental mice were fed control diet or diet containing freeze-dried Kimchi at the level of 5%(w/w) or 5% freeze-dried Kimchi with 2% APCE supplementation. The main ingredient of Kimchi was Korean cabbage and fermentation was carried out at $4^{\circ}C$ for three weeks. Freeze-dried 2% APCE supplementation was added to Kimchi at the begining of fermentation. In order to investigate the effect of Kimchi intake of APCE supplementation (5%Kimchi-2%APCE), the following was performed; body weight, food intake, hematological parameter, serum level of mouse interleukin-4 (mlL-4) and mouse interferon-$\gamma$ (mIFN-$\gamma$ ), and, the percentage of CD3+/CD4+, CD3+/CD8+, B220+ in splenic cells. The results of final body weight, and food diet intake of two Kimchi groups were lower than those of the control group (not supplemented experimental diet). The hematology change obtained from the level of WBC (white blood cell) and platelet were not affected by feeding different dietary regiments, but the level of RBC (red blood cells) HB (hemoglobin), and spleen weight of two Kimchi groups were increased significantly than those of the control group. The serum level of IL-4 and IFN-$\gamma$ of two Kimchi groups were increased significantly than those of the control group, also enhanced the percentages of the CD3+/CD4+ and CD3+/CD8+ by 5% freeze-dried Kimchi, and 5%Kimchi-2%APCE group were 43.9 and 65.2%, and 96.0 and 208% than those of the control group, respectively. From these results, it can be concluded that Kimchi itself has an immuno-stimulatory effect and Kimchi contaning 2% APCE supplementation has the more pronounced effect in vivo system.

In this study, we have investigated the effect of Biphenyl Dimethyl Dicarboxylate (DDB), a synthetic analogue of Schizandrin C isolated from Schizandrae Fructus on cytochrome $P_450$ lAl and 2Bl, and the protective mechanism against $CCl_4-induced$ hepatotoxicity in rat liver. After DDB was administered into male rats for different periods of time (1~7 days) and with different doses (25, 50, 100 and 200 mg/kg), mRNA levels of CYPlAl were measured by polymearse chain reaction (PCR) and assayed the activities of CYPlAl specific ethoxyresorufin-O-dealkylase (EROD) and CYP2Bl specific benzyloxyresorufin-O-dealkylase (BROD). DDB treatment resulted in increase in CYP2Bl mRNA level and BROD activity, whereas there was no change in CYPlAl mRNA level and EROD activity. This effect of DDB was time-and dose-dependent and reached maximal level by 3 day and 200 mg/kg treatment. In addition, rats were pre-treated with DDB at doses of 25, 50 or 100 mg/kg daily for 4 days, 3-hr after final treatment on the 4th day, $CCl_4$ 0.3ml/kg was intraperitonially injected into the rats to examine the effect of DDB on $CCl_4-induced$ hepatic injury. Serum levels of ALT and AST were determined and histopathological examination was done in rat liver. Furthermore, we have measured hepatic microsomal malondialdehyde(MDA) level, a parameter of lipid peroxidation. Based on serum ALT level and lipid peroxidation, pretreatment of DDB, 50 mg/kg appeared the most protective effect against $CCl_4-induced$ heapatotoxity. These results indicate that DDB stimulates CYP2Bl mRNA level and BROD activity in time and dose dependent manner and suggest that protective effect of DDB on $CCl_4-induced$ hepatotoxicity may be mediated through free radical scavenging.

This study investigated the relationship of Helicobacter pylori (H. pylori) infection to iron-deficiency anemia in high school girls. Four hundred and fourty-five subjects resided in Ulsan City in Korea were evaluated by questionnaire or blood analysis for serum indicators of iron status, daily nutrient intakes, symptoms of anemia, and H. pylori IgG antibody status. In H. pylori infected subjects, total energy intake of was 1534.14±350.81 kcal (73.0% of the Korean RDA), the iron intake of subjects was 11.38±3.90 mg (71.1% of Korean RDA) and calcium intake was 467.63±175.96 mg (58.3% of the Korean RDA). Carbohydrate (p < 0.05), vitamin A (p < 0.05), vitamin C (p < 0.01) intakes were significantly lower in infected subjects than in non-infected subjects. The prevalence of anemia (hemoglobin (Hb) < 12 g/dL.) in H. pylori infected subjects was 22.7% as compared to 14.7% in non-infected subjects. The mean serum ferritin of infected subjects (21.71±21.50 ng/mL) was significantly lower than in non-infected subjects (p < 0.05) (as was the mean Hb concentration (12.54±1.51 g/dL) and hematocrit (37.99±3.64%)). Total iron binding capacity (TIBC) of H. pylori infected subjects (449.09±78.23 ㎍/dL) was significantly higher than that of non-infected subjects (432.99＋76.15 ㎍/dL) (P < 0.05). The levels of iron, red blood cell (RBC) and transferrin saturation were similar in infected and non-infected subjects. Two symptoms of anemia, 'pale face (p < 0.01)' and 'decreased ability to concentrate (p < 0.005)', were significantly higher in H. pylori infected subjects than in non-infected subjects. High school girls are known to be more vulnerable to iron deficiency than other age groups, and this research demonstrates that infection with H. pylori increases their risk of iron-deficiency anemia.

The present study aimed to evaluate the effect of Eucommia ulmoides extracts on rheumatoid arthritis biomarker in a CIA-induced DBA/1 mice. For evaluation, Eucommia ulmoides extracts was administered orally at dose of 100 mg/kg/day for 4 weeks after production of an animal model of rheumatoid arthritis and we confirmed the treatments' effects based on serum biomarker, radiological, structural parameter analysis. Compared to the negative control group, the Eucommia ulmoides extracts treatments significantly reduced the serum level of inflammation and immunoglobulin markers (i.e., TNF-α, IgG, and hs-CRP), and significantly decreased the monocyte count of white blood cells. Furthermore, the Eucommia ulmoides extracts treatments effectively preserved the joint destruction, and little the joint deformation. Moreover, compared to the negative control group, the Eucommia ulmoides extracts treatments increased the bone volume, and significantly decreased bone inflammation. The results indicate that the Eucommia ulmoides extracts improved rhrumatoid arthritis symptoms. Thus, the Eucommia ulmoides extracts may be a novel therapeutic option for the management of rheumatoid arthritis.

Objectives : Obesity is a public health concern associated with chronic diseases including hyperlipidemia, diabetes, fatty liver, atherosclerosis and cancer. As several anti-obesity drugs have been limited owing to their side effects, the development of new anti-obesity drugs through herbal medicines has been increasing. Cynanchum Wilfordii Radix (CW) traditionally is consumed for various health benefits including immune enhancing, anti-inflammation and anti-tumor activities. The aim of the present study is to evaluate the effects of CW on High fat diet (HFD)-induced obese mice. Methods : The mice were randomly divided into four groups (n=7). The mice were respectively fed a normal diet (ND), a high-fat diet (HFD), HFD plus CW (50 mg/kg/day), HFD plus CW (100 mg/kg/day). All groups were assayed for body weights, food efficiency ratio, blood biochemistry parameters, and organic tissue weights. Results : HFD-fed mice showed an increase in the body weight and serum biochemistry parameters levels (total cholesterol and triglycerides) as well as organic tissue weights. However, the administration of CW to obese mice induced a reduction in their body weight, food efficiency ratio, blood biochemistry parameters and weight of liver and fat compared with the HFD fed mice. Additionally, we observed that CW inhibited the lipid accumulation in liver and serum lipid parameter induced by HFD. Conclusions : Taken together, the findings of this study suggest that CW may be a potential agent for use in the treatment of obesity and obesity-related metabolic diseases.

This study was conducted to investigate the productivity, meat quality, blood variables, stress responses, and litter quality of broilers offered feed with different levels of Glycine (Gly) supplementation under heat stress condition. A total of 760 one-day-old Ross 308 broiler males were randomly assigned to one of the four dietary treatment groups: (1) basal diet (control; CON); (2) basal diet + Gly 0.1% (Gly 0.1%); (3) basal diet + Gly 0.2% (Gly 0.2%); and (4) basal diet + Gly 0.3% (Gly 0.3%). The environments for all the treatments groups were maintained according to broiler rearing guidelines from day 1 to day 21, and heat stress condition (32 ± 1℃, 60 ±5%) was created from day 22 to the end. The addition of Gly increased weight gain and affected feed intake (p < 0.05). Gly 0.1% group had higher pH and ferric reducing antioxidant power (FRAP) in the chicken meat and lower heterophil (HE)/lymphocyte (LY) ratio in the blood (p < 0.05). In particular, Gly 0.2% treatment group had lower serum corticosterone level (p < 0.05) than other groups. For jejunum morphology, the addition of Gly 0.2% significantly reduced the depth of the crypts (p < 0.05). However, the addition of Gly did not significantly affect litter quality (p > 0.05). In conclusion, the addition of glycine improved productivity and meat quality, alleviated heat stress, and improved intestinal function. Further studies are needed to determine the optimal level and mechanism of action of the additive when ingested.

Background : The established by Light et al in 1972 have been used widely for the differential diagnosis of the pleural effusions in transudates and exsudates. However, in recent years, several reports have agreed that these criteria misclassified an important number of effusions. For this reason, different parameters have been proposed for differentiating the transudates from exudates. Nevertheless, all these alternative parameters have not been better than the past criteria of Light et al. In response the usefulness of two parameters for differentiating pleural transudate from exudates were evaluated : pleural fluid cholinesterase level and pleural fluid to serum cholinesterase ratio. Methods : A total of forty-three patients with known causes of the pleural of the pleural effusion by diagnostic thoracentesis were studied. The following criteria for differentiating the pleural effusions in transudates and exsudates were analyzed : Ligt's criteria, the pleural fluid cholesterol level, the pleural fluid to serum cholesterol ratio, the pleural fluid cholinesterase level, and the pleural fluid to serum cholinesterase ratio. Results : The conditions of forty-three patients were diagnosed. Ten were classified as having transudates and thirty-three as exudates. The percentage of effusions misclassified by each parameter was as follows : Light's criteria, 9.3% ; pleural fluid cholesterol 2.3% ; pleural fluid to serum cholesterol, ratio, 2.3% ; pleural fluid cholinesterase, 4.7% ; and pleural fluid to serum chlinesterase ratio, 2.3%. Conclusions : The pleural fluid to serum cholinesterase ratio is one of the accurate criteria for differentiating pleural transudates from exudates. If fur1her studies confirm the results, the cholinesterase ratio could be used as the first step in the evaluation of pleural effusion and, if evaluated together with the other criteria, the differentiation of pleural transudate from exsudates will become more accurate.

Background: Among the respiratory diseases, there are a lot of cases of pleural effusion. The most common cause is tuberculosis. But the other cause such as lung malignancy is in an increasing tendency because of the development of diagnostic procedure, the decrease of the prevalence of the tuberculosis and the increase of the longevity. We need to know the accurate diagnosis as soon as possible for the correct therapy. Method: A clinical observation was made on 315 cases of pleural effusion seen at Pusan Adventist Hospital, from Jan, 1989 to Dec, 1992. For diagnostic procedure, thoracentesis, lymph node biopsy, bronchoscopy and percutaneous biopsy of the parietal pleura with Cope needle were performed. The following are parameters used in seperating the exudate from the transudate: pleural protein 3.0 g/dl, pleural protein/serum protein ratio 0.5, pleural LDH 200 IU, pleural LDH/serum LDH ratio 0.6, pleural cholesterol 60 mg/dl and pleural cholesterol/serum cholesterol ratio 0.3. Each parameters were compared, and misclassified rate and diagnostic efficiency were calculated. Results: The most common cause of exudate pleurisy was tuberculosis (82.3%) and malignancy was next (12.2%). The chief complaints of pleural effusion were noted as dyspnea (58.7%), chest pain (54.9%), coughing (50.2%) and fever (36.2%). Location of pleural effusion was noted as right side (51.4%), left side (41.3%) and both sides (7.3%). Amount of pleural effusion of the chest X-ray was minimum (46.8%), moderate (40.5%) and maximum (12.7%). Misclassified rates for each parameters in seperating the exudates from the transudates were as follows; protein: 5.2%, pleural protein/serum protein:7.6%, LDH: 13.9%, pleural LDH/serum LDH: 6.9%, cholesterol: 8.0%, pleural cholesterol/serum cholesterol: 5.6%. On the pleural biopsy, the tuberculosis granuloma was 60.8%, malignancy was 13.6%, infection was 2.3% and nonspecific inflammatory reaction was 23.3%. Conclusion: on the basis of the above results, the most common cause of exudative pleurisy was tuberculosis. We think that the plerual cholesterol/serum cholesterol ratio is the most useful supportive parameter in separating the exudates from the transudates. For accurate diagnosis, the pleural biopsy is the first procedure and repeated pleural biopsy of nonspedcific inflammatory reaction is required.

Background : Angiogenesis is an essential process for the growth and metastatic ability of solid tumors. One of the key factors known to be capable of stimulating tumor angiogenesis is the vascular endothelial growth factor (VEGF). The serum VEGF concentration has been shown to be a useful parameter related to the clinical features and prognosis of lung cancer and has been recently applied to a the malignant pleural effusion showing a correlation with the biochemical parameters. The VEGF has been shown to play a role in the inflammatory diseases, but rarely in the tuberculosis (TB). The serum and pleural fluid VEGF levels were measured in patients with lung cancer and TB. Their relationship with the clinical and laboratory parameters and repeated measurement 3 months after various anticancer treatments were evaluated to assess the utility of the VEGF as a tumor marker. Methods : Using a sandwich enzyme-linked immunosorbent assay, the VEGF conoentration was measured in both sera and pleural effusions collected from a total of 85 patients with lung cancer, 13 patients with TB and 20 healthy individuals. Results : The serum VEGF levels in patients with lung cancer ($619.9{\pm}722.8pg/ml$) were significantly higher than those of healthy controls ($215.9{\pm}191.1pg/ml$), However, there was no significant difference between the VEGF levels in the lung cancer and TB patients. The serum VEGF levels were higher in large cell and undifferentiated carcinoma than in squamous cell carcinoma and adenocarcinoma. The serum VEGF levels of lung cancer patients revealed no significant relationship with the various clinical parameters. The VEGF concentrations in the malignant effusion ($2,228.1{\pm}2,103.0pg/ml$) were significantly higher than those in the TB effusion ($897.6{\pm}978.8pg/ml$). In the malignant pleural effusion, the VEGF levels revealed significant correlation with the number of red blood cells (r=0.75), the lactate dehydrogenase (LDH)(r=0.70), and glucose concentration (r=-0.55) in the pleural fluid. Conclusion : The serum VEGF levels were higher in the lung cancer patients. The VEGF levels were more elevated in the malignant pleural effusion than in the tuberculous effusion. In addition, the VEGF levels in the pleural fluid were several times higher than the matched serum values suggesting a local activation and possible etiologic role of VEGF in the formation of malignant effusions. The pleural VEGF levels showed a significant correlation with the numbers of red blood cells, LDH and glucose concentrations in the pleural fluid, which may represent the tumor burden.

This study was carried out to investigate the effects of dietary energy levels on growth performance, blood parameter, and intestinal morphology of Pekin ducks in low temperature. A total of 500, 21-d-old Pekin ducks (initial BW = 1,089 ± 5.21 g) were evenly assigned to five dietary treatments (2,950, 3,000, 3,050, 3,100, or 3,150 kcal AME/kg, calculated on an as-is basis) with four replicates (pens) for each treatment (25 ducks per pen). During the experiment, hens were provided with feed and water ad libitum. Overall, increasing dietary energy levels corresponded to an increase of final body weight and body weight gain (linear, p < 0.01). Feed intake decreased (linear, p < 0.01) and feed conversion ratio increased (linear, p < 0.01) with increasing levels of energy. There were no significant differences (p < 0.05) in the level of leukocytes between groups. However, heterophils decreased (quadratic, p < 0.05) and lymphocytes increased (linear, p < 0.01) as inclusion of dietary energy levels increased. The H/L ratio increased (linear, p < 0.01) with increasing dietary energy levels while serum corticosterone levels decreased at overall experimental periods. Triglycerides increased (linear and quadratic, p < 0.05) with increasing dietary energy levels. There were no significant changes in villus height or crypt depth of the jejunum at overall experimental. In conclusion, increasing concentrations of dietary energy levels up to 2,950-3,150 kcal/kg in diet. Additionally, 3,150 kcal/kg dietary energy had been revealed more beneficial and could be practiced as protective management for the Pekin ducks reared under low ambient temperature (8℃ to 10℃).
