IgG4-related disease is a fibroinflammatory condition by infiltration of IgG4-positive plasma cells that often presents as a tumorous lesion. This disease can affect nearly every organ system. After the pancreas, the head and neck region is second most common site for presentation of IgG4-related disease such as Mikulicz's disease, Küttner tumor. The involvement of IgG4-related disease in laryngeal lesions is extremely rare. We have experienced a case of IgG4-related disease with pseudotumor formation in the larynx that is suggestive of malignancy in radiologic findings. But the pathology findings was finally confirmed as IgG4-related disease. Oral treatment with prednisolone was initiated, and the edematous mass reduced in size without permanent functional impairment of vocal fold mobility. We report our experience with a literature review.

Piglet health at weaning is compromised due to several stress factors. Following the ban of antibiotic growth promoters new alternatives are required to control these problems. This paper reviews the evidence available for the use of spray dried animal plasma (SDAP) as an alternative to antibiotics in weaning pigs. Data from 75 trials in 43 publications involving over 12,000 piglets (mean values) have been used to calculate the performance responses of piglets according to several factors including SDAP origin, protein source from the control diet being replaced, dose of inclusion, age and weight of the piglets at weaning, sanitary conditions and simultaneous use or not of medication. Although the use of SDAP of all origins results in positive responses, it appears that plasma from porcine origin has the highest efficacy. This could be explained by the specificity of its IgG against porcine pathogens. During the first week post-weaning the response to plasma appears to increase with the inclusion dose, although over the two-week pre-starter period an optimal inclusion level of 4-8% is suggested. SDAP improves feed efficiency more markedly when the piglets are challenged with an experimental infection or when feed does not contain medication, which could be indicative of a lower expenditure of energy and nutrients to build an immune response against the challenge. There is evidence supporting that SDAP IgG and other bioactive substances therein prevent the binding of pathogens to the gut wall and reduce the incidence of diarrhoea in the post-weaning phase. Overall, plasma can be postulated as an excellent alternative to in-feed antimicrobials for piglets in the post-weaning phase.

We investigated the effect of aqueous extract of Terminalia chebula (Combretaceae)(TCAE) on the immediate hypersensitivity reaction in vivo and in vivo. TCAE (0.01 to 1 g/kg) dose-dependently inhibited compound 48/80 induced systemic anaphylaxis in mice. When TCAE was pretreated at concentrations ranging from 0.01 to 1 g/kg, the plasma histamine levels were reduced in a dose-dependent manner. TCAE (0.1 and 1 g/kg) significantly inhibited local immunoglobulin E (IgE)-mediated passive cutaneous anaphylactic reaction. TCAE (0.001 to 1 mg/ml) also dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-dinitrophenyl (DNP) IgE. TCAE (0.01 to 1 mg/ml) had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis $factor-{\alpha}$ production from RPMC. These results indicate that TCAE inhibits immediate hypersensitivity reaction in vivo and in vitro.

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) has been reported to exert detrimental toxicities on various organ systems including reproductive, cardiovascular, nervous, or dermal system. Immunomodulatory effects of TCDD is thymic atrophy, downregulation of cytotoxic T or B lymphocyte differentiation and activation, which were demonstrated using experimental animals, whereas immunotoxicity in human has not been investigated well. This study was proceeded to evaluate general immunologic spectrum of the Korean Vietnam War veterans exposed to TCDD during their operation, and compare with that of the non-exposed control subjects with similar age. Regarding composition and quantity, immune cells in peripheral blood collected from the TCDD-exposed was not much different from those of the control except decreased red blood cell, hemoglobin and hematocrit level. Furthermore, plasma IgG2, G3, and G4 isotype distribution was similar between two groups, but IgG1 level was significantly lowered in the TCDD-exposed, indicating a TCDD-mediated functional alteration of B cells. Significantly enhanced level of IgE in plasma, a hallmark of dermal or respiratory allergic response, was also observed in the TCDD-exposed compared with that of the control. Elevated generation of IL-4 and IL-10 was resulted from in vitro stimulation of T cells with PMA plus ionomycin or PHA, respectively, from the TCDD-exposed in comparison to those of the control, suggesting a skewed type-2 response. In addition, the level of IFN${\gamma}$, a multifunctional cytokine for T cell-mediated immunity, was lowered in the TCDD-exposed with upregulation of tumor necrosis factor $\alpha$. The present study suggests that TCDD exposure disturbs immunohomeostasis in humans observed as an aberrant plasma IgE and IgG1 levels and dysregulation of T cell activities.

This study was designed to investigate the effects of vitamin E supplementation on radical scavenger activity and immune responses in female judo athletes(n=18). The age and sex matched sedentary students were used as controls(n=15). The initial plasma vitamin E concentration, lipid peroxide level and radical scavenger activity (RSA) were not different between two groups. The supplementation of $\alpha$-tocopheryl acetate(400IU/d) for 4 weeks significantly increased plasma vitamin E concentration of the subjects in both groups. In addition, the decrease in thiobarbituric acid reactive substance(TBARS)(p<0.05) and enhancement of RSA(p<0.05) were observed in both groups. Percentages of total T-cells in the athletic group was lower than that in the control group(p<0.05). However, the ratio of CD4 / CD8(helper T-cal $l^pressor T-cell) was higher in the sports group, due to more decrease in CD8 subset than in CD4 subset. The concentrations of IgG and IgM in the sports group were significantly lower than those in the control group(p<0.05). Therefore, severe training of the athletic group seems to be associated with the changes of supplementation. In conclusion, vitamin E supplementation (400IU/d, 4 weeks) of the female university students improved antioxidative activities of the blood, by decreasing lipid peroxide and enhancing radical scavenger activity. Percentages of T lymphocytes and IgG and IgM concentrations in the athletic group were lower than those in the control group. Meanwhile, vitamin E supplementation had no effects on immune status in both groups.ps.

Neck mass has various etiologies, including inflammatory, congenital, neoplastic causes. The IgG4-related disease can cause symptoms in the head and neck areas with an inflammatory neck mass. It also shows clinical and pathological findings from inflammation caused by immune reactions, such as lymphocyte and plasma cell infiltration, storiform fibrosis, obliteration phlebitis, and invigorated serum IgG4 levels. The treatment guideline has not been established and still under debate, but systemic glucocorticoid seems to be effective in the most cases. In this brief report, a 48-year-old male patient presented with voice change for 3 weeks. Left side paramedian vocal fold palsy was observed in the flexible laryngoscopy. About 2.5×2.0×1.2cm size, heterogeneously enhanced neck mass with irregular margin encasing left carotid artery was noted on preoperative contrast enhanced neck CT scan, and it was suspicious of left carotid body tumor. The pathology shows IgG4-related disease rather than carotid body tumors. We report this case of IgG4-related disease, which can be misdiagnosed to carotid body tumors.

We investigated the effect of aqueous extract of Gleditsia sinensis thorns (Leguminosae) (GSAE) on the mast cell-dependent anaphylaxis. GSAE (0.005 to 1 ${g}/kg$) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80 in rats. GSAE (0.1 and 1 ${g}/kg$) also significantly inhibited local anaphylaxis activated by anti-DNP IgE. When GSAE was pretreated at the same concentrations with systemic anaphylaxis, the plasma histamine levels were reduced in a dose-dependent manner. GSAE (0.001 to 1 ${m}g/ml$) dose-dependently inhibited the histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80 or anti-DNP IgE. The level of cyclic AMP in RPMC, When GSAE (1 ${m}g/ml$) was added, transiently and significantly increased about fourfold compared with that of basal cells. Moreover, GSAE (0.01 and 0.1 ${m}g/ml$) had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-$\alpha$ production from RPMC. These results suggest a possible use of GSAE in managing mast cell-dependent anaphylaxis.

Forty-eight Naemi lambs (avg. BW 31.7 kg) were transported by truck for a distance of 1,450 km from Al-Jouf to Riyadh, Saudi Arabia. On arrival day, the lambs were randomly allocated to four groups receiving diets supplemented with 0.0, 0.3, 0.6 and 0.9 ppm organic chromium (Cr). Each group consisted of four separately housed replicates of three lambs each. The animals were fed ad libitum on a grower diet for 84 days. Blood samples were obtained shortly before transportation, upon arrival and at weekly intervals thereafter from all lambs for analysis of plasma and serum. Plasma glucose and serum cortisol, total protein, albumin, urea-N and total cholesterol concentrations were determined. A cursory clinical examination of the lambs, along with rectal temperature, was undertaken at different intervals during the experiment. The lambs were inoculated each with 2 ml i.v. chicken red blood cells (CRBC) on days 0, 21, and 42. Serum total, IgG and IgM antibody titers were determined at weekly intervals post-immunization. An in vivo intradermal hypersensitivity test was carried out on 6 lambs from each group on days 10 and 70. Transportation of the lambs resulted in a significant (p<0.001) elevation of serum cortisol, total protein and albumin levels, as well as increased plasma glucose concentration, with corresponding decrease in total cholesterol, while blood urea-N remained largely unchanged. These constituents returned to normal levels during subsequent weeks, with no significant differences in their concentrations being observed between the Cr-supplemented groups and controls. Rise in rectal temperature after transportation was reduced to a greater extent (p<0.05) in Cr-supplemented versus control lambs. Total, IgG and IgM antibody titers against CRBC rose significantly (p<0.05) during immunizations in all groups, with significantly and linearly higher (p<0.05) total and IgG titers in Cr-supplemented versus control lambs. By contrast, no significant effect due to Cr supplementation was recorded in IgG titers, which increased equally in Cr-fed and control groups. Skin thickness in response to intradermal inoculation of phytohaemagglutinin (PHA) was also significantly (p<0.01) increased as a result of Cr supplementation. These results indicate that dietary Cr supplementation might be useful during stress especially for enhancing immune responses in transport-stressed lambs.

Objectives : To investigate the immunological activities, we evaluated the combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix (AG) on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. Methods : The cellular proliferation and the production of nitric oxide were examined in a macrophage cell line, RAW 264.7 cells, in the presence of the combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix. C57BL/6 mice were immunized intraperitonially with ovalbumin/aluminium ($100{\mu}g/200{\mu}g$) on day 1, 8, and 15. The combination ratio of Aconiti Lateralis Radix Preparata and Glycyrrhizae Radix (1 g/kg/day) was orally administrated for 3 weeks. On day 22, splenocyte and plasma were collected for mitogen-induced proliferation, lymphocyte subpopulation by flow cytometry and measurement of AST (Aspirate aminotransferase), ALT (Alanine aminotransferase), and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes). Results : Aconiti Lateralis Radix Preparata treatment had no influence on immune responses. The proliferation and NO production of macrophage and proliferation of splenocyte were increased as the higher ratio of Glycrrhizae Radix. The proliferation of splenocyte, lymphocyte subpopulation and production of antibody (total IgM, OVA-specific IgG and OVA-specific IgG1) were increased as the higher ratio of Glycrrhizae Radix on OVA-immunzed mice. Conclusions : These results suggest that the higher ratio of Glycyrrhizae Radix can increase immunological activities such as NO production in RAW264.7 cells, splenocyte proliferation and immunoglobulin production in OVA-immunized mice.

This study was carried out to evaluate the immunomodulatory capacity of edible mushrooms, including Sarcodon aspratus, Letinus edodes and Grifola frondosa in mice. BALB/c mice were administered 50, 500, and 1000 mg/kg body weight of various mushrooms five times a week over 4 weeks through oral administration. The control mice were administered distilled water. No significant changes in body weight were observed. IL-4 and $IFN{\gamma}$ production was evaluated with splenic T lymphocytes stimulated in vitro with phytohemagglutinins for 48 hr. The mice group administered Sarcodon aspratus, Grifola frondosa tend to higher ratio of $IFN{\gamma}$ versus IL-4 than the other groups. In addition, the ratio of plasma IgG2a versus IgG1 was also elevated in mice treated with Sarcodon aspratus. These results indicated that Sarcodon aspratus can enhance type-1 helper T cell-mediated cellular immunity. And also, S. aspratus seems to be one of the most useful mushrooms for immunomedicine.
