  • Purpose: To evaluate whether the levels of immunoglobulin G (IgG) antibody to Tanerella forsythia are associated with periodontal status. Methods: Patients with a diagnosis of chronic periodontitis were considered candidates for the study; thus 80 chronic periodontitis patients and 28 healthy persons (control group) were invited to participate in this investigation. The presence of T. forsythia was detected by polymerase chain reaction (PCR) analysis using primers designed to target the respective 16S rRNA gene sequences. Peripheral blood was collected from each subject to identify the IgG1 and IgG2 serum antibodies against T. forsythia. All microbiological and immunological laboratory processes were completed blindly, without awareness of the clinical status of the study patients or of the periodontal sites tested. Results: The bivariate analysis showed that lower mean levels of clinical attachment level (CAL) and probing depth were found in the presence of the IgG1 antibody titers against whole-cell T. forsythia; however, only the difference in CAL was statistically significant. In the presence of the IgG2 antibody titers against whole-cell T. forsythia, the periodontal parameters evaluated were higher but they did not show statistical differences, except for plaque. The unadjusted linear regression model showed that the IgG1 antibody against whole-cell T. forsythia in periodontitis patients was associated with a lower mean CAL (${\beta}=-0.654$; 95% confidence interval [CI], -1.27 to -0.28; P<0.05). This statistically significant association remained after adjusting for possible confounders (${\beta}=-0.655$; 95% CI, -1.28 to -0.29; P<0.05). On the other hand, smoking was a statistically significant risk factor in the model (${\beta}=0.704$; 95% CI, 0.24 to 1.38; P<0.05). Conclusions: Significantly lower mean levels of CAL were shown in the presence of the IgG1 antibody titers against whole-cell T. forsythia in periodontitis patients. Thus, the results of this study suggest that IgG1 antibody to T. forsythia may have been a protective factor from periodontitis in this sample.

  • The changes in serum total protein and immunoglobulin levels, and BVD, IBR and PI-3 viral neutralizing antibody titers in colostrum-conferred Korean native calves during the first 12 weeks postpartum were studied, and the results obtained were summerized as follows: The Mean concentration of total protein, total immunoglobulin, IgG, IgM and IgA in sera of 9 calves at birth were $3.8{\pm}0.5g/dl$, $0.27{\pm}0.15mg/ml$, $0.06{\pm}0.08mg/ml$, $0.21{\pm}0.11mg/ml$, and extremely low concentration, respectively. Serum total protein level reached a maximum at 20 hours after birth, total immunoglobulin, IgG, and IgM levels at 24 hours, and IgA level at 28 hours, respectively. Serum IgA level reached a minimum at 4 weeks old, IgM level at 5 weeks, total immunoglobulin level at 8 weeks, and IgG level at 10 weeks, respectively. After then those levels had begun to increase, but total protein level was still decreasing at 12 weeks old. The half-lives of IgG, IgM, and IgA were 21.1 days, 4.0 days, and 2.6 days-respectively. In 10 Korean native cows immediately after parturition, serum neutralizing antibody titers specific to BVD, IBR and PI-3 virus were $8.7{\pm}1.5{\log}_2$, $5.7{\pm}1.2{\log}_2$, and $6.8{\pm}1.01{\log}_2$, respectively. And colostral neutralizing antibody titers against BVD, IBR, and PI-3 virus were $10.1{\pm}1.4{\log}_2$, $6.8{\pm}1.3{\log}_2$ and $7.8{\pm}1.7{\log}_2$, respectively. Before suckling the colostrum, SN antibody titers against BVD, IBR, and PI-3 virus were undetectable from all of 9 Korean native calves. Nevertheless SN antibody titer against BVD virus reached a maximum level ($9.2{\pm}0.6{\log}_2$) at 24 hours after birth, that against IBR virus ($6.1{\pm}1.0{\log}_2$) at 20 hours after birth, and that against PI-3 virus ($6.8{\pm}0.9{\log}_2$) at 32 hours after birth, respectively. In 12 weeks old calves, the SN antibodies against BVD and IBR virus were still decreasing, but that against PI-3 virus reached a minimum at 10 weeks, and increased after 12 weeks of age. The half-lives of SN antibodies against BVD, PI-3 and IBR, virus were 16.0 days, 22.6 days, and 25.5 days, respectively.

  • Objective : The water extract of Bojungikgi-tang (BTE) composed with Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Cimicifuga Rhizoma, and Bupleuri Radix and it has been traditionally used for chronic diseases or weakness after illness in oriental countries. However, little is known about the effects of aqueous extract of BTE on trimellitic anhydride (TMA)-induced contact hypersensitivity (CHS). Therefore, the aim of this study was to investigate the effects of BTE on TMA-induced CHS in BALB/c mice.Methods : In this study, the extract of BTE was prepared by extracting with distilled water at 100℃ for 2.5 h. The extract was freeze-dried following filtration through 0.45 μm filter. Mice were orally administrated with or without BTE extract of different doses (25-200 ㎎/㎏/day) for 28 days. During the challenge period, mice were externally applied with different doses of BTE extract one time per day 30 min before TMA treatment. I examined the effects of BTE on the serum levels of IgE, IgG1, IgG2a, and IgG2b, nitric oxide (NO) and prostaglandin E2 (PGE2) production in isolated peritoneal macrophages, Th2 cytokine production in isolated spleen cells, ear swelling responses, and the leukocyte infiltration induced by TMA.Results : The orally and externally administration of BTE dose-dependently reduced the serum levels of hapten-specific immunoglobulin E (IgE), IgG1 titer, and PGE2 production as well as ear swelling responses and leukocyte infiltration in TMA-induced BALB/c mice. The levels of NO and PGE2 production from peritoneal macrophages stimulated with TMA-BSA were markedly suppressed by pretreatment with BTE in a concentration dependent manner. Furthermore, the levels of Th2 cytokines (IL-4, IL-5, IL-13) production from spleen cells stimulated with ConA were markedly suppressed by BTE treatment in a concentration dependent manner.Conclusions : These results suggest that BTE treatment suppresses chronic contact hypersensitivity, and it can be assumed that the suppression of ear swelling, serum IgE, NO and PGE2 levels, leukocyte infiltration, and Th2 cytokines in an animal model. Therefore, these properties may contribute to the strong anti-CHS response effect of BTE.

  • 본 연구는 세 종류의 Porphyromonas gingivalis(Pg) antigen의 IgG subclass associated recognition을 평가하기 위해 수행했었다. 총 35명의 조기발병형치주질환자중, Pg381에 대한 IgG2항체의 증가를 보이는 5명이 급속진 행형 치주질환자, IgG4의 증가를 보이는 6명의 환자(국소유년형 치주질환자 2명과 급속진행 형 치주질환자 4명), IgG2+4의 증가를 보이는 2명의 급속진행형 치주질환자 그리고 IgG1+2+4의 증가를 보이는 8명의 환자(국소 유년형 치주질환자 2명과 급속진행형 치주질환자 6명)으로 구성된 21명의 환자를 dot immunoblot analysis를 위해 선택했다. 실험에 사용된 정제된 항원은 Pg381에서 추출한 43-kd fimbrilin protein과 lipoplysaccharide(LPS), Pg A7A1-28(ATCC 53977)에서 추출한 capsularpolysaccharide(CPS)였다. Immunoblotting pattern은 IgG4 antibody가 fimbrial antigen에 강력히 반응함을 보여주었다. Fimbriae에 잘 반응하는 몇몇의 IgG4 antibody역시 antigen에 대해 양성반응을 보였다. 대조적으로 IgG2는 CPS antigen을 일차적으로 인식했다. 전부는 아니지만 대부분의 경우, single이나 group화된 IgG subclass는 모두 LPS antigen을 인식하지 못했다. 같은 group에서 염색강도의 개인적인 차이는 증명되었다. 이런 결과는 조기발 병형 치주질환에서 Pg의 fimbriae와 CPS가 immunodominant antigen이 될 수 있음을 제시한다. 더욱이 IgG subclass antibody가 이런 Pg의 immunoglobulin antigen을 선택적으로 인식함을 알았고, 이는 조기발병형치주질환의 병리에 immunodominant antigen과 함께 IgG의 기능적인 역할을 고려해야 함을 제시한다.

  • Purpose : In order to evaluate the time of disappearance of cytomegalovirus(CMV) IgG antibodies from mothers, and the alteration of the positive rate of CMV IgG antibodies among preschool period children, we investigated the positive rate of CMV antibodies among preschool children. Methods : We studied 391 children who visited the Department of Pediatrics from March, 2001 to February, 2004. We measured the serum CMV IgG of 217 children and the serum CMV IgM of 358 children. Results : The positive rate of CMV IgG antibodies is 83.9 percent(the number of positive IgG children is 182 out of 217). The alteration of the positive rate is 92.9 percent in 0-3 months, 75.0 percent in 4-6 months and the nadir was 20.0 percent in 7-9 months. Then, the positive rate increased to 83.9 percent in 22-24 months. After 22 months, the positive rate was 92.1 percent(the number of positive IgG children was 105 out of 114). The positive rate of CMV IgM antibody by age is 3.3 percent in 0-1 months, 3.6 percent in 1-2 months, 10.5 percent in 2-3 months, 14.3 percent in 3-4 months, 14.3 percent in 4-5 months, and then the results of five children among 148 children were positive. The distribution was one in 22-23 months, one in 25-26 months, one in 27-28 months, one in 28-29 months, one in 40-41 months. We discovered IgM positive children succesively from birth to 5 months, but sporadically after 5 months. Conclusion : The CMV IgG from mothers has decreased since birth and the time of nadir is 7-9 months. But it increases to a mean value of 83.9 percent at 22-24 months because of perinatal or postnatal infections.

  • The objective of the study was to evaluate the effect of passive transfer status, determined by measuring serum immunoglobulin (Ig) concentration 24 hours after parturition, on growth performance in buffalo calves allowed to nurse the dam during the first month of life. Serum Ig concentration 24 hours after birth ranged from 28.1 to 35.9 mg/ml, birth weight ranged from 29 to 41 kg, body weight 30 days after birth ranged from 48.5 to 62.9 kg. The Average Daily Gain (ADG) from birth to day 30 ranged from 448 to 1,089 g/d. Significant linear associations were detected between serum Ig concentration 24 hours after birth and day-30 weight (p< 0.05; $R^2$ = 0.31) and between serum Ig concentration 24 hours after birth and ADG from birth to day 30 (p<0.001; $R^2$ = 0.72). Results indicated that passive transfer status was a significant source of variation in growth performance when buffalo calves nursed the dam. Maximizing passive transfer of immunity by allowing calves to nurse the dam can increase growth performance during the first month of life.

  • Background: Symptomatic multiple myeloma (MM) is an acquired B-cell malignant proliferation of antibody secreting plasma cells, characterized by end organ damage due to monoclonal immunoglobulin secretion. The aim of this study wa to determine the stage stratification according to an international scoring system in adult Pakistani MM patients at presentation. Materials and Methods: This single centre retrospective study extendedfrom January 2012 to December 2015. Data were retrieved from the departmental maintained records. Results: A total of 39 patients were diagnosed at our center with MM during the period of the study, 25 males and 14 females. Age ranged between 36 and 81 with a mean of $54.5{\pm}14.8$ and a median of 57 years. Common presenting complaints included fatigue (80.9%), backache (79.3%) and bone pain (66.2%). Overall, 9 patients were in ISS stage I (23%), 12 were in stage II (30.7%) and 18 were in stage III (46.1%). Out of the total, 29 (74.3%) had kappa immunoglobulin andthe remaining 10 (25.6%) had lambda type myelomas. IgG myeloma was commonest, seen in 26 (66.6%) followed by IgA in 11 (28.2%) with non secretory myeloma in one (2.5%) and light chain disease also in one patient (2.5%). Conclusions: MM in Pakistani patients is seen in a relatively young population with male predominance. Primarily patients are symptomatic and risk stratification revealed a predominance of advanced stage III disease in our setting.

  • Purpose : Previously, Epstein-Barr virus (EBV) infection was diagnosed by serological examination; currently, many EBV antigen detection methods have been developed and applied clinically for diagnosing EBV infection. To delineate the clinical characteristics of EBV infection, clinical and laboratory findings were evaluated for patients who tested positive in EBV polymerase chain reaction (PCR). Methods : EBV PCR was conducted in 352 patients admitted to the pediatric ward from January 2004 to December 2006, with more than 2 clinical signs such as fever (${\geq}37.5^{\circ}C$), exudative throat infection, lymphadenopathy, hepatitis of unknown etiology, and splenomegaly. The EBV viral gene was detected by PCR in 115 patients (32%), and the clinical characteristics of these patients were evaluated. Laboratory findings such as leukocytosis, thrombocytopenia, atypical lymphocyte, and alteration in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in peripheral blood were examined. The EBV-specific immunoglobulin M antibody (EBV-IgM Ab) was also tested. Results : Most of the children were younger than 8 years (89%), and the male to female ratio was 1.3:1. Exudative throat infection and fever (${\geq}37.5^{\circ}C$) were observed in all patients. Cervical lymph node enlargement was seen in 36 patients (31 %); leukocytosis ($WBC{\geq}10,000/mm^3$), in 54 patients (47%); and atypical lymphocyte (${\geq}20%$), in 28 patients (24%). EBV-IgM Ab was positive in 33 patients (29%). The younger patients had higher ALT levels and higher incidence of positive EBV-IgM Ab than the older patients. Conclusion : The cumulative number of patients diagnosed to have EBV infection by PCR increased markedly for those under 8 years. ALT was higher and EBV-IgM Ab was detected more in younger patients with EBV infection.

  • The characteristics of Holstein colostrum according to the methods that were employed in processing it were analyzed in this study to improve its industrial utilization. Colostrum samples were collected from the dairy farm of the National Institute of Animal Science (NIAS). The milk fat, protein, lactose, and SNF contents of colostrum were 4.34, 6.99, 3.37, and 11.10%, respectively. The effects of spray drying, freeze drying, freezing, acidification, and inoculation of lactic-acid bacteria on the characteristics of colostrum were then compared. The freezing of colostrum was found to be proper for long-term storage in a farm. Freeze-dried colostrum powder could not meet the processing requirements and the component standards for animal products in terms of the total bacterial and coliform bacteria counts, but spray-dried colostrum powder could meet the microbiological requirements because of its bactericidal effect during the spray-dry treatment. The inoculation of lactic-acid bacteria showed a better inhibitory effect on coliform than the acidification treatment, but protein precipitation appeared because of the low pH and the high acidity. To estimate the effects of the processing methods employed on the IgG of colostrum, the IgG contents of the milk treated by long temperature long time (LTLT) ($65^{\circ}C$, 30 min), by inoculating the lactic acid bacteria starter, by spray drying, and by freeze drying were measured. The IgG contents of the colostrum were changed significantly by the processing treatment employed, from 53.98 mg/mLto 33.28, 34.82, 21.98, and 36.89 mg/mL, respectively.

  • This experiment was conducted to investigate the effects of dried mealworm (Tenebrio molitor larva) on growth performance, nutrient digestibility and blood profiles in weaning pigs. A total of 120 weaning pigs ($28{\pm}3days$ and $8.04{\pm}0.08kg$ of body weight) were allotted to one of five treatments, based on sex and body weight, in 6 replicates with 4 pigs per pen by a randomized complete block design. Supplementation level of dried mealworm was 0%, 1.5%, 3.0%, 4.5%, or 6.0% in experimental diet as treatment. Two phase feeding programs (phase I from 0 day to 14 day, phase II from 14 day to 35 day) were used in this experiment. All animals were allowed to access diet and water ad libitum. During phase I, increasing level of dried mealworm in diet linearly improved the body weight (p<0.01), average daily gain (ADG) (p<0.01) and average daily feed intake (ADFI) (p<0.01). During phase II, ADG also tended to increase linearly when pigs were fed higher level of dried mealworm (p = 0.08). In addition, increasing level of dried mealworm improved the ADG (p<0.01), ADFI (p<0.05) and tended to increase gain to feed ratio (p = 0.07) during the whole experimental period. As dried mealworm level was increased, nitrogen retention and digestibility of dry matter as well as crude protein were linearly increased (p = 0.05). In the results of blood profiles, decrease of blood urea nitrogen (linear, p = 0.05) and increase of insulin-like growth factor (linear, p = 0.03) were observed as dried mealworm was increased in diet during phase II. However, there were no significant differences in immunoglobulin A (IgA) and IgG concentration by addition of dried mealworm in the growth trial. Consequently, supplementation of dried mealworm up to 6% in weaning pigs' diet improves growth performance and nutrient digestibility without any detrimental effect on immune responses.
