In this study, we investigated the effects of frankincense essential oil (BSEO) on the immune cell change in the lung, BALF and PBMC using a mouse model of asthma. BALB/c mice after intraperitoneal OVA sensitization (day 1) were challenged intratracheally with OVA on day 14. Then, the asthma was induced by repeated OVA inhalation challenged. The asthma induced mice group inhaled 0.3% BSEO for 30 minutes per trial, three times a week, for 8 weeks using the nebulizer. After 12 weeks from the experiment, the mice was killed and the lung, bronchoalveolar lavage fluid (BALF) and peripheral blood mononuclear cell (PBMC) were obtained. Next, the change of immune cells inside the separated tissues was observed to identity the effects of BSEO on the allergic asthma mice. In conclusion, the hypersensitive reaction of airway to the bronchoconstrictor in the allergic asthma induced mice was effectively suppressed in Frankincense group, in Bermagot, Eucalyptus, Chamomile, Marjoram and Frankincense groups, the natural aromatic essential oil groups. Furthermore, it was also confirmed that the weight of lung, total number of alveolus cells and the number of BALF, MNL and DLN increased after inducing allergic asthma were reduced. BSEO suppressed the percentage of $CD3e^+/CD19^-$, $B220^+/CD23^+$ and $CD11b^+/Gr-1^+$ cells in the lung tissue of allergic asthma mice. Moreover, BSEO also reduced the percentage of $CD4^+/CD8^-$, $B220^+/CD23^+$ and $CD3^+/CCR3^+$ cells in BALF. In addition, the percentage of $CD3e^+/CD19^-$, $CD3^+/CD69^+$ and $B220^+/CD23^+$ cells in PBMC was reduced. The results of this study indicate that BSEO would be effective to treat allergic asthma by the immune control suppressing the activity of immune cells in each tissue.

Raw oyster (Crassostrea gigas) was inoculated with Vibrio parahaemolyticus and Escherichia coli, treated with high hydrostatic pressure and evaluated for microbial counts. Cell death of V. parahaemolyticus (Vp) increased with the increase of applied pressure. Vp starting inoculum of $3.8{\times}10^5\;CFU/mL$ was totally eliminated after exposure to 200 MPa for 10 min at $22^{\circ}C$ Viable cell of Vp decreased with the increase in treatment time and dropped below the detection limit with treament of 25 min at $22^{\circ}C/150\;MPa$. The number of Vp by treatment of $0^{\circ}C$ and $10^{\circ}C$ for 20 and 25 mon at 100 MPa, respectively. For E. coli, there was an initial lag up to 250 MPa gollowed by a rapid decline. Treatment at 325 MPa/$22^{\circ}C$ for 15 min caused 5-log reduction, while that at 375 MPa resulted in total reduction of starting inoculum of $4.0{\times}10^7\;CFU/mL$. Lower treatment temperature showed higher killing effect of E. coli at the same treatment pressure and time. Viable cell of E. coli decreased with the increase in treatment time, and 4-log reduction was achieved with treatment of 5 min at $10^{\circ}C$/350 MPa and then total reduction was achieved after treatment of 15 mon. Higher pressure, lower temperature and longer time were more effective in sterilizing V. parahaemolyticus and E. coli.
Neutral salt-soluble, hot water-soluble and methanol-soluble materials (hereinafter referred to Fr. NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from sclerotium of Grifola umbellata. The Fr. NaCl and Fr. HW did not show any direct cytotoxicity against NIH3T3, Sarcoma 180 and MCF-7, but Fr. MeOH showed cytotoxicity against these cell lines at the concentration of $1,000\;{\mu}g/ml$. Intraperitoneal injection with Fr. NaCl showed antitumor effect with life prolongation of 66.7% and decrease the number of Sarcoma 180 cells of 54.2% in mice inoculated with Sarcoma 180. Fr. NaCl improved the immunopotentiation activity through alternative complement pathway and the alkaline phosphatase activity by $85.05{\sim}88.73%$ and 6 folds, respectively. The number of peritoneal exudate cells and the circulating leucocytes were increased by 1.7 and 3.6 folds in the Fr. NaCl treating group compared with the control group, respectively. The weight of immunoorgans such as liver, spleen and thymus were also gradually increased. The hematological analysis of the Fr. NaCl group was similar with that of the control group. The total polysaccharide and protein contents of Fr. NaCl were 98.25% and 1.44%, respectively. These results indicate that the antitumor activity of Fr. NaCl was exerted through immunopotentiation, but not through cytotoxicity against the tumor cells.
Humulus japonicus is an ornamental plant in the Cannabaceae family. Although the mode of action of Humulus japonicus is not fully understood, a strong relationship was observed between anti-inflammatory and anticancer in some types of cells. Recent studies also have shown that Humulus japonicus possesses anti-inflammatory activities and may significantly improve antioxidant potential in Raw 264.7 macrophage cells. Thus, the aim of this study was evaluated the effect of Humulus japonicus extract on sperm motility and subsequent preimplantation developmental competence of the bovine embryos. After in vitro maturation, the oocytes with sperms were exposed in in vitro fertilization (IVF) medium supplemented with Humulus japonicus extract (0.01, 0.05, $0.1{\mu}g/mL$, respectively) for 1 day. In our results, exposure of IVF medium to Humulus japonicus extract did not affect sperm motility and percentage of penetrated oocytes but ROS intensity was significantly decreased by $0.01{\mu}g/mL$ compared with other groups (p< 0.05). Moreover, treatment with $0.01{\mu}g/mL$ of Humulus japonicus extract was higher the frequency of blastocyst formation than the any other groups (p<0.05). Otherwise, treatment with $0.01{\mu}g/mL$ of Humulus japonicus extract not increased the total cell number but reduced apoptotic-positive nuclei number. In conclusion, our results indicate that supplementation of Humulus japonicus extract in IVF medium may have important implications for improving early embryonic development in bovine embryos.
A 2${\times}$3 factorial arrangement of treatments was used to determine the effects of olaquindox and cyadox on immune response of Landrace${\times}$Large-White geld piglets that had been orally given 10$^{10}$ CFU of Escherichia coli (E. coli, O$_{139}$:K$_{88}$). Factors included (1) E. coli inoculation or control, and (2) no antimicrobials, 100 mg/kg olaquindox and 100 mg/kg cyadox in the basal diet respectively. E. coli inoculums were orally administered 7 days after the diets were supplemented with olaquindox and cyadox. The effects of the two antimicrobials were assessed in terms of: (1) average daily gain (ADG), (2) systemic immune response (the number of white blood cells and lymphocytes, leukocyte bactericidal capacity, lymphocyte proliferation response to PHA, immunoglobulin concentrations, and total serous hemolytic complement activity), and (3) intestinal mucosal immunity including the number of intraepithelial lymphocytes (IELs) and immunoglobulin A secreting cells (ASCs) in the intestinal lamina propria. E. coli inoculation reduced ADG (p<0.05) during the period of d 0 to d 14 after the challenge while the antimicrobial supplementations improved ADG (p<0.01) during the experiment. ADG in cyadox-supplemented pigs was higher (p<0.05) than that in olaquindox-supplemented pigs. The antimicrobials decreased IEL and ASC counts in the jejunum and ileum (p<0.01) while E. coli inoculation caused them to increase (p<0.01). Jejunal ASCs in the cyadox-supplemented pigs were lower (p<0.05) than those in the olaquindox-supplemented. E. coli elicited increase (p<0.05) in white blood cell counts, leukocyte bactericidal capacity, lymphocyte proliferation rate, serous IgA concentrations, and serous hemolytic complement activity. The antimicrobials decreased the measured systemic immune parameters, but not significantly (p>0.05). The data suggest that olaquindox and cyadox suppress E. coli-induced immune activation, especially intestinal mucosal immune activation, which may be involved in the observed growth promotion.
The normal physiological values of Korean mongrel dogs were studied, comparing them with foreign references, on the basis of control physiological data measured on 110 cases out of the dogs submitted to the experiments in our department. The hemodynamic measurements varied widely between the both limits of reported normal control data, with the mean value of heart rate $140.4{\pm}26.6$/min., and both the systolic and diastolic arterial blood pressures $137.2{\pm}31.7$mmHg and $104.7{\pm}14.4$ mmHg, as well as the venous pressure of $9.11{\pm}2.18$ cm.$H_2O$. Hematologically, the number of red blood cells $4,571,000{\pm}767,000$per cu.mm., the amount of hemoglobin $11.57{\pm}3.74$ gm/dl and the hematocrit $37.3{\pm}7.2$ per cent, were equally the values a little lower than the reported normal means. However, the white blood cells were within the reported normal limits both in number, $10,384{\pm}4,877$ per cu. mm and their differential counts with slightly broader ranges of variation. The platelet count was $149,800{\pm}47,000 $per cu. mm and was also far below the normal, while the coagulation time $9.03{\pm}2.69$min. and the prothrombin time $13.17{\pm}6.52$sec were within normal limits, though a little prolonged. The serum electrolytes, Na $146.6{\pm}10.44$mEq/L.,K $4.46{\pm}0.84$mEq/L., CI $118.3{\pm}7.88$mEq/L. and Ca $11.45{\pm}5.62$mg./dl, and the blood glucose level of $94.9{\pm}31.79$mg./dl were essentially not different from the reported normal values. The serum proteins, total protein $7.15{\pm}1.41$gm/dl., albumin $4.09{\pm}0.77$gm./dl. and globulin $3.18{\pm}0.88$gm/dl. were included near the higher limits of the reported normal levels. The thymol turbidity 0.1-3.04 units were normal in 10 cases, and the cephaline flocculation was within normal range except 2 cases out of 26 dogs, showing two positive in 24 hours. And the nitrogen series, NPN $34.61{\pm}10.29$mg/dl. and BUN $12.77{\pm}6.37$mg./dl. were normal. It may be concluded that from the point of view of hereby measured physiological data compared with the foreign references, the Korean mongrel dogs have a compatible laboratory data with only the special regards to their tendency toward anemia in red blood cell series.
This used a new method to capture the neighbouring relationship among parcels. To define the neighbouring relationship, all the surrounding parcels in the study area can be identified as neighbours of the current parcel as long as they touch each other even at a point. To examine neighbouring parcels on all polygons of the study area, this study used ArcViews avenue programming which visited each polygon in turn and produced an outfile containing the parcel record ID and the contents of each of the adjacent parcels. The second thing is to translate the record IDs of neighbouring parcels into land use. For this, this study used the Lookup function in Excel to obtain neighbouring land use. To deal with how to calculate the ratio of each land use to neighbouring land uses, this study used Visual Basic. finally, this study considered a term of neighbour land use as the ratio of the number of urban use adjacent parcels to the total number of adjacent parcels. This study shows that GIS and spatial analysis can be applied to land use change in the urban fringe area at a very detailed level using municipal parcel data which occupies about 80% of administrative affairs, especially at the local government level in Korea. The results of analysis can be useful for local government to understand its situation and to manage land use efficiently in the urban fringe. The methodology developed in this study is especially useful for an empirical approach.

Purpose: This study was conducted to investigate the immune responses of children with moderate and severe novel influenza A virus (H1N1) pneumonia, and to compare their clinical and immunological findings with those of control subjects. Methods: Thirty-two admitted patients with H1N1 pneumonia were enrolled in the study. The clinical profiles, humoral and cell-mediated immune responses of the 16 H1N1 pneumonia patients who were admitted to the pediatric intensive care unit (severe pneumonia group), 16 H1N1 pneumonia patients admitted to the pediatric general ward (moderate pneumonia group) and 13 control subjects (control group) were measured. Results: Total lymphocyte counts were significantly lower in patients with H1N1 pneumonia than in the control group (P=0.02). The number of CD4+ T lymphocytes was significantly lower in the severe pneumonia group ($411.5{\pm}253.5/{\mu}L$) than in the moderate pneumonia ($644.9{\pm}291.1/{\mu}L$, P=0.04) and control ($902.5{\pm}461.2/{\mu}L$, P=0.01) groups. However, the number of CD8+ T lymphocytes was significantly higher in the severe pneumonia group ($684.2{\pm}420.8/{\mu}L$) than in the moderate pneumonia ($319.7{\pm}176.6/{\mu}L$, P=0.02) and control ($407.2{\pm}309.3/{\mu}L$, P=0.03) groups. The CD4+/CD8+ T lymphocytes ratio was significantly lower in the severe pneumonia group ($0.86{\pm}0.24$) than in the moderate pneumonia ($1.57{\pm}0.41$, P=0.01) and control ($1.61{\pm}0.49$, P=0.01) groups. The serum levels of immunoglobulin G, immunoglobulin M and immunoglobulin E were significantly higher in the severe pneumonia group than in the 2 other groups. Conclusion: The results of this study suggest that increased humoral immune responses and the differences in the CD4+ and CD8+ T lymphocyte profiles, and imbalance of their ratios may be related to the severity of H1N1 pneumonia in children.

Background: Esophageal cancer (EC) is among the most common malignancies in Eastern Africa, but the occurrence of EC in Sudan has rarely been described in the scientific literature. This paper reports the results of a consecutive case series of all EC patients who visited one of the two public cancer treatment centers in the country in 1999-2012, providing a first description of this disease in a treatment center located in central Sudan. Materials and Methods: Clinical and demographic data for all EC patients who visited the Department of Oncology of the National Cancer Institute at the University of Gezira (NCI-UG) from 1999 to the end of 2012 were abstracted and tabulated by sex, tumor type and other characteristics. Results: A total of 448 EC patients visited NCI-UG in 1999-2012, and the annual number of EC cases increased steadily from 1999. Squamous cell carcinoma (SCC) was the predominant EC tumor type (90%), and adenocarcinoma (ADC) was reported in 9.4% of the EC cases. The overall male-to-female ratio for EC was 1:1.8, but the ratio was tumor type-dependent, being 1:2 for SCC and 2:1 for ADC. Only 20% of EC patients reported having ever used tobacco and/or alcohol, and the vast majority of these patients were male. At the time of EC diagnosis, 47.3% of the patients resided in Gezira State. Some EC patients from Gezira State seek out-of-state treatment in the national capital of Khartoum instead of visiting NCI-UG. Conclusions: The annual number of EC patients visiting NCI-UG has increased in recent years, approximately half of these patients being from Gezira State. Although this consecutive series of EC patients who visited NCI-UG was complete, it did not capture all EC patients from the state. A populationbased cancer registry would provide more complete data required to better understand EC patterns and risk factors.
Interferon(IFN) is a sort of glycoproteins that are produced by activated lymphocyte, monocyte and fibroblast. IFN has anti-viral effects, immuno-defensive mechanism and regulating properties to the several kinds of cells that includes affect on the bone formation and resorption. The effect of IFN on the osteoclast & other tissue cells has been studied in a number of researchers with the limited reports on the osteoblast. The purpose of this study was to evaluate the effects of IFN on the osteoblastic function. The MC3T3/El cell(Mouse osteoblast) was incubated in ${\alpha}-minimum$ essential medium containing 10% FBS. To detect the cytotoxic effect of $IFN-{\gamma}$ on osteoblast, the cells were cultured in 96-well plate to which $IFN-{\gamma}$ of various concentrations were added for 2 days. After staining with trypan blue, total cells and living cells were counted under microscope. To determine the activity of alkaline phosphataset(ALP), various concentrations of $IFN-{\gamma}$ were treated to culture medium, and biochemical assay was performed. $IFN-{\gamma}$ and $IFN-{\gamma}$ plus cycloheximide were added to culture medium separately and then ALP activity were determined. To detect the effect of the $IFN-{\gamma}$ on the bone formation of osteoblast, long-term culture was performed, and calcified nodule formation were observed using von Kossa's staining. After the addition of $IFN-{\gamma}$ with various concentrations to the medium, no cytotoxic effect of $IFN-{\gamma}$ was detected at any concentration. The significant increase in ALP activity of osteoblast were found the concentration of $IFN-{\gamma}$ 500-2500U/ml and the culture time of 24-48 hours respectively. The enhancement of ALP activity by $IFN-{\gamma}$ of osteoblast was decreased significantly by the treatment of cycloheximide. After long-term culture of osteoblast, the nodule formation was found to be increased in number and density by the addition of 500 U/ml $IFN-{\gamma}$. These results suggest that $IFN-{\gamma}$ was affected on the bone formation of osteoblast. Forthemore this kind of study or $IFN-{\gamma}$ to osteoblast will be held continuously.
