  • The present study has been performed to develop a PCR technology to identify human immunoglobulin(Ig) allotypes with restriction fragment length polymorphism(RFLP) using a probe. Genomic DNA were ampilified with PCR tecnology using primers from peripheral blood lymphocytes of 10 periodontal patiens, whose Ig allotypes have been pre-determined by serological tecnique using heagglutination technique. The result indicated that the RFLP patterns could successfully differentiate the Ig allotypes, which suggests that this technology can be developed as a tool useful for population genetics studies.

  • An American Cocker Spaniel (3-year-old, intact female, 6.0 kg) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University for evaluation of pustules and crusts in the periocular region, dorsal and ventral region of the trunk, and digits. Complete blood count (CBC) revealed leukocytosis with mature neutrophilia, and a serum biochemistry profile revealed hypoalbuminemia. Tape strip tests identified numerous neutrophils and acatholytic cells. Histopathology identified intraepithelial pustules with neutrophils and acantholytic keratinocytes. Definitive diagnosis of pemphigus foliaceus (PF) was made by direct immunofluorescence (DIF) test with goat anti-canine IgG antibody. The human intravenous immunoglobulin (IVIG) was administered at a rate of 15 ml/h over 6 hours for 4 days. After that, the dog was maintained on prednisolone (2.2 mg/kg, PO, SID) and azathioprine (2.0 m/kg, PO, SID). An infusion of IVIG (0.5 g/kg) was repeated 3 days after 4 weeks. After 10 weeks, the dog showed the remarkable regression of lesions.

  • Mice were fed semi-purified diets containing 0, 2, 10 and 25 ppm(mg/kg) deoxynivalenol over 8 weeks and were assessed for effects on bodyweight gain, serum immunolglobulin levels and surface immunoglobulin bearing lymphocyte ratio. 1. The rate of body-weight gain was significantly reduced (p<0.05) at the 10 and 25 ppm of DON, whereas the mice ingesting the diet containing 2 ppm DON was not. 2. IgA in serum immunolglobulin was significantly increased (P<0.05) at the 10 and 25 ppm of DON, but IgG, IgM were decreased, whereas exposure to 2 ppm DON was not change. 3. Concentration of IgA from Peyer's patch of mice fed DON exhibited increased at 10, 25 ppm. 4. Lymphocytes surface marker studies revealed that IgA, IgG and IgM were 2.2%, 0.4% and 1.5% respectively. These results suggest that dietary exposure to DON alters regulation of IgA production

  • In fish vaccinology, the secondary antibodies against fish immunoglobulins (Igs) are necessary to measure specific humoral immune responses in immunized fish. In the present study, polyclonal antiserum against olive flounder (Paralichthys olivaceus) IgM heavy chain was generated by intramuscular immunization of rabbit with Escherichia coli/eukaryotic shuttle vector containing open reading frame (ORF) of olive flounder IgM heavy chain. Western blot analysis demonstrated the specific activity of the rabbit antiserum with reduced olive flounder serum H chain at dilutions up to 1:1000. Titer of immunized rabbit serum against olive flounder serum was significantly higher than that of pre-immunized rabbit serum when determined by ELISA.

  • Intravenous immunoglobulin (IVIg) is the treatment of choice for many autoimmune neuropathic disorders such as Guillain-Barre syndrome (GBS), chronic inflammatory Demyelinating neuropathy (CIDP), and multifocal motor neuropathy (MMN). IVIg is preferred because the adverse reactions are milder and fewer than the other immune-modulating methods such as steroid, other immunosuppressant such as azathioprine, and plasmapheresis. IVIg also has been used in other autoimmune neuromuscular disorders (inflammatory myopathy, myasthenia gravis, and Lambert-Eaton myasthenic syndrome) and has been known as safe and efficient agent in these disorders. Since IVIg would get more indications and be used more commonly, clinicians need to know the detailed mechanism of action, side effects, and practical points of IVIg.

  • As a novel approach for disease control and prevention, nutritional modulation of the intestinal health has been proved. However, It is still unknown whether branched-chain amino acid (BCAA) is needed to maintain intestinal immune-related function. The objective of this study was to determine whether BCAA supplementation in protein restricted diet affects growth performance, intestinal barrier function and modulates post-weaning gut disorders. One hundred and eight weaned piglets ($7.96{\pm}0.26kg$) were randomly fed one of the three diets including a control diet (21% crude protein [CP], CON), a protein restricted diet (17% CP, PR) and a BCAA diet (BCAA supplementation in the PR diet) for 14 d. The growth performance, plasma amino acid concentrations, small intestinal morphology and intestinal immunoglobulins were tested. First, average daily gain (ADG) (p<0.05) and average daily feed intake (ADFI) (p<0.05) of weaned pigs in PR group were lower, while gain:feed ratio was lower than the CON group (p<0.05). Compared with PR group, BCAA group improved ADG (p<0.05), ADFI (p<0.05) and feed:gain ratio (p<0.05) of piglets. The growth performance data between CON and BCAA groups was not different (p>0.05). The PR and BCAA treatments had a higher (p<0.05) plasma concentration of methionine and threonine than the CON treatment. The level of some essential and functional amino acids (such as arginine, phenylalanine, histidine, glutamine etc.) in plasma of the PR group was lower (p<0.05) than that of the CON group. Compared with CON group, BCAA supplementation significantly increased BCAA concentrations (p<0.01) and decreased urea concentration (p<0.01) in pig plasma indicating that the efficiency of dietary nitrogen utilization was increased. Compared with CON group, the small intestine of piglets fed PR diet showed villous atrophy, increasing of intra-epithelial lymphocytes (IELs) number (p<0.05) and declining of the immunoglobulin concentration, including jejunal immunoglobulin A (IgA) (p = 0.04), secreted IgA (sIgA) (p = 0.03) and immunoglobulin M (p = 0.08), and ileal IgA (p = 0.01) and immunoglobulin G (p = 0.08). The BCAA supplementation increased villous height in the duodenum (p<0.01), reversed the trend of an increasing IELs number. Notably, BCAA supplementation increased levels of jejunal and ileal immunoglobulin mentioned above. In conclusion, BCAA supplementation to protein restricted diet improved intestinal immune defense function by protecting villous morphology and by increasing levels of intestinal immunoglobulins in weaned piglets. Our finding has the important implication that BCAA may be used to reduce the negative effects of a protein restricted diet on growth performance and intestinal immunity in weaned piglets.

  • This experiment was conducted to investigate the effects of dietary supplementation of magnesium sulfate ($MgSO_4$) during late gestation and lactation on sow and litter performance, fecal moisture, blood biochemistry parameters, immunoglobulin levels and milk composition in sows. Forty-eight sows ($Yorkshire{\times}Landrace$, 4th to 5th parity) were randomly allocated to 1 of 4 dietary treatments supplemented with 0, 200, 400, or 600 mg/kg $MgSO_4$ (n = 12). The experiment started on day 90 of gestation and continued through day 21 of lactation. Blood samples were collected on day 107 of gestation, day 0 (farrowing) and 21 (weaning) of lactation for the analyses of the blood biochemistry parameters and immunoglobulin levels. The colostrum and milk samples were obtained on day 0 and 14 of lactation, respectively. Fecal samples were collected from the sows on day 107 of gestation as well as day 7 and 20 of lactation to determine fecal moisture content. The results showed that the survival percentage of piglets and the litter weight at weaning were decreased linearly (p<0.05) and other parameters of the sow or litter performance were not influenced (p>0.05) by $MgSO_4$ supplementation. The fecal moisture content of the sows were increased (p<0.05) linearly as dietary $MgSO_4$ increased on day 7 and 20 of lactation. Supplementation with $MgSO_4$ increased the plasma magnesium (Mg) level linearly (p<0.05) and had a trend to increase total protein level (p>0.05 and p<0.10). However, an increase in the dietary $MgSO_4$ level resulted in a linear decrease in the colostrum fat content (p<0.05). Dietary $MgSO_4$ supplementation enhanced the immunoglobulin G (IgG) level (linear, p<0.05) in plasma on day of farrowing and immunoglobulin A (IgA) level in colostrum (quadratic, p<0.05) and milk (linear, p<0.05) of the sows. These results indicated that supplementation with $MgSO_4$ during late gestation and lactation may have the potential to prevent sow constipation, but may also result in some negative effects.
