To understand immunopharmacologic effects on Cervi Pantotrichum Cornu, Morindae Officinalis Radix, Cistanches Herba, Curculginis Rhizoma, Epimedii Herba, Eucommiae Cortex, we investigated chinese experimental documents, and we could reach conclusions as follows : 1. The effects on cell-mediated immune system were as follows. 1) The effects on macrophage (1) The herbal medicines promoting to increase the number of WBC in the peripheral blood were Morindae Officinalis Radix, Epimedii Herba and that promoting to reinforce the phagocytic functions of neutrophil was Curculginis Rhizoma. (2) The herbal medicines promoting the phagocytic functions of mononuclear, macrophage were Cervi Pantotrichum Cornu, Cistanches Herba, Eucommiae Cortex. 2) The herbal medicines stimulating the activities of T lymphocytes were Cervi Pantotrichum Cornu, Curculginis Rhizoma, Epimedii Herba, Eucommiae Cortex. 2. The effects on humoral immune system were as follows. 1) The herbal medicines increasing the activity of complement receptor were Cervi Pantotrichum Cornu, Curculginis Rhizoma. 2) The herbal medicines reinforcing immunity of spleen cells were Cervi Pantotrichum Cornu, Cistanches Herba, Epimedii Herba. 3) The herbal medicines promoting proliferation of spleen cells that produce antibody after having been immunized by SRBC were Cervi Pantotrichum Cornu, Cistanches Herba, Epimedii Herba. 3. The herbal medicines, reinforcing immunity on delayed type hypersensitivity were Cervi Pantotrichum Cornu, Cistanches Herba, Eucommiae Cortex. As you know in the many bibliological documents, the studies on the effects of Drugs for Tonifying Yang were started along right lines. Recently the studies on those were accomplished more rapidly and applied many immune diseases. We thought that Drugs for Tonifying Yang could be important immunopotentiators. Therefore we can apply those herbal medicines not only to immune diseases but also inflammatory diseases, senile infirmity and all sorts of tumor.

The present study was conducted to investigate the effects of dietary supplementation of Codonopsis pilosula extract powder (CEP) on the reproductive performance in sows. A total of 20 pregnant sows were randomly assigned to two dietary treatments, which was given a corn and soybean meal-based diets containing 0 or 5 g/kg of the CEP from 40 days prepartum to weaning (25 days postpartum). The serum immunoglobulin G (IgG) concentration of sow (p<0.01) and piglets (p<0.05) was significantly increased by the feeding of CEP. And we also demonstrated that the coefficient of correlation between the colostrum and serum indicates a significant positive correlation on IgG. The stillbirth of sows and mortality rate during suckling periods were slightly lower in CEP feeding group than control, but there is no significant difference. In conclusion, our results suggest that the dietary supplementation of CEP increases the humoral immunity in both of sows and piglets, and it might contribute to improve the reproductive performance of sows. Further, additory studies are necessary on the immunomodulatory mechanism of CEP components.

A series of animal experiments has been carried out to investigate the potential antigenicity of the FCS (Fetal Calf Serum) which is commonly used to enhance viability of preserved aortic allograft. Aorti allografts were processed using nutrient media without FCS(control group) or with 10% FCS(study group). After 14 days of 4$^{\circ}C$ cold storage and cryopreservation, antigenic expression of allograft rondothelial cells were studied using immunohistochemical study. To determine antigenicity, level of Anti-MHC class I Antibody, anti-MHC class II antibody and anti-lCAM 1 antibody were measured. There were no stAtistically significant differences in all antigenic expression between control group and study group(p=0. 524 in MHC class I expression, p=0.897 In MHC class II expression, p=0.1305 in ICAM 1 expression). With this result, antigenicity provoking effect of FCS could not be proven. Thus, FCS may not be eliminated from the nutrient media for preservation of aortic allograft due to its proven benefit of cell viability enhancement.

There are very scant data on the epidemiology of primary immunodeficiency diseases (PIDs) in Korea. Here we attempted to estimate the PID epidemiology and disease burden in Korea. A systematic review was performed of studies retrieved from the PubMed, KoreaMed, and Google Scholar databases. Studies on PIDs published in Korean or English between January 2001 and November 2018 were analyzed. The number of PID patients and the healthcare costs were estimated from Health Insurance Review and Assessment Service (HIRA) Korea data for 2017. A total of 398 PID patients were identified from 101 reports. Immunodeficiencies affecting cellular and humoral immunity were reported in 11 patients, combined immunodeficiency with associated or syndromic features in 40, predominantly antibody deficiencies in 144, diseases of immune dysregulation in 58, congenital defects of phagocytes in 104, defects in the intrinsic and innate immunity in 1, auto-inflammatory disorders in 4, complement deficiencies in 36, and phenocopies of PID in none. From the HIRA reimbursement data, a total of 1,162 outpatients and 306 inpatients were treated for 8,166 and 6,149 days, respectively. In addition, reimbursement was requested for 8,200 outpatient and 1,090 inpatient cases and $1,924,000 and $4,715,000 were reimbursed in 2017, respectively. This study systematically reviewed published studies on PID and analyzed the national open data system of the HIRA to estimate the disease burden of PID, for the first time in Korea.

Single-cycle viruses generated by reverse genetic technology are replication-incompetent viruses due to the elimination of gene(s) essential for viral replication, which provides a way to overcome the safety problem in attenuated viruses. Infectious hematopoietic necrosis virus (IHNV) is a major pathogen causing severe damage in cultured salmonid species. In the present study, we generated a single-cycle IHNV lacking the transmembrane and cytoplasmic domain in the G gene (rIHNV-GΔTM) and evaluated the prophylactic potential of rIHNV-GΔTM in rainbow trout (Oncorhynchus mykiss). To produce rIHNV-GΔTM, IHNV G protein-expressing Epithelioma papulosum cyprini (EPC) cells were established. However, as the efficiency of rIHNV-GΔTM production in EPC cell clones was not high, fish were immunized with a low-tittered single-cycle virus (1.5 × 10² PFU/fish). Despite the low dose, the single-cycle IHNV induced significant protection in rainbow trout against IHNV infection, suggesting high immunogenicity of rIHNV-GΔTM. No significant difference in serum ELISA titers against IHNV between the rIHNV-GΔTM immunized group and the control group suggests that the immunized dose of rIHNV-GΔTM might be too low to induce significant humoral adaptive immune responses in rainbow trout. The involvement of adaptive cellular immunity or innate immunity in the present significantly higher protection by the immunization with rIHNV-GΔTM should be further investigated to know the protection mechanism.

We present a case of The Miller Fisher Syndrome (MFS), showing a remission during a recently developed noninvasive therapy. Two weeks after an appearance of cough and fever, a 35 years old Japanese male developed diplopia, ataxia and numbness of his fingers and toes. He was diagnosed as MFS, and a fixed dose of prednisolone acetate (60mg/day) was administered for 3 months, but little improvement was observed. In addition to this administration, we tried 20 minutes of Photic Feedback (PFB) treatment daily for 40 days. The PFB system detects brain waves from the subject's forehead, and extracts alpha waves by the band-pass filter with a center frequency set at 10.0Hz. It also simultaneously modulates the augmentation of a red light-emitting diode, corresponding with the amplitudes of the extracted alpha waves. In this treatment, this adjusted photic stimulation was given to the subject's closed eyes, resulting in the effective alpha enhancement by photic driving response. The numbness increased during each of PFB treatment, but the symptoms started to improve gradually after 10 days. Other symptoms disappeared after 40 days. CD20 levels increased with this treatment. This case suggests that the PFB treatment may speed the natural remission of MFS. This treatment may be worth considering in patients who suffer polyneuropathy.

Humoral and cellular immune responses are depressed in chickens infected with reticuloendotheliosis virus(REV). The extent of depression is influenced by the age of infection and strain of virus. This study was conducted for investigation of immunosuppressive effects of a Korean isolate of REV. Chickens infected with REV-HI, a Korean isolate, at 1 day old were severely suppressed in the vaccinal immunity against Newcastle disease, infectious bronchitis and infectious bursal disease. But these immunosuppressive effects were not observed in chickens infected with the virus at 2 weeks of age, or contact infected by growing in-contact with inoculated chickens from one day old. The clinical signs following infectious laryngotracheitis(ILT) vaccination in chickens infected with REV-HI at 1 day old were more severe than those of uninfected chickens, and some of REV-infected chickens(21.4%) were died after the vaccination. Mortality following virulent ILT virus infection was increased in REV-HI infected chickens. Effects of REV infection at one day old to susceptibilities to subsequent Chicken anemia agent (CAA) infection were also studied. Chickens were infected with REV-HI at 1 day old and subsequently inoculated CAA at 1, 7, 14 and 28 days old, respectively. Mortalities of the chickens infected with REV-HI and subsequent CAA infection were 100, 100, 40 and 0%, respectively, whereas 23, 8, 0 and 0% of chickens infected with only CAA were died, respectively. These above all results suggest that a Korean isolate of REV may be highly immunosuppressive.

We have previously reported the minimum criteria that can be applied to evaluate efficacy and safety of a DNA vaccine with use of Streptococcus pneumoniae DNA vaccine (SPDNA). The SPDNA was formulated by inserting the DNA sequences that are codons specific for the carbohydrate epitope in the capsule of S. penumoniae by phage display peptide library. Administration of the SPDNA into mice induced both humoral and cell-mediated immunities. The induction was protective even in the absence of CD4+ T lymphocyte in mice. Profiles of cytokine and isotyping of antibody displayed tendency of the Th1. In continuation of these studies, we examined if the efficacy of the SPNDA was provoked by the peptide recognized by codons specific for the capsule. Results showed that the peptide vaccine formulae (SPP) induced protective antibody in mice as did the SPDNA. Involvement of the cell-mediated immunity was also determined. Possible side effects of autoimmune diseases such as myositis and C3a production and tumor-formation were undetectable in mice given 7 times of SPDNA vaccination during entire of 92 days. Even after the frequent immunization, immunogenicity of the SPDNA was observed as determined for antibody production, suggesting that there was no immunotolerance provoked. All together, these examining factors would be applied to measurement of a DNA vaccine safety regarding the immunopathological aspect.

The adjuvant effects of Korean mistletoe lectin-C (KML-C) were investigated following the oral administration of KML-C with ovalbumin (OVA) as an antigen. Mice were orally immunized with OVA alone or admixed with various doses of KML-C or cholera toxin (CT), and the titer of OVA-specific antibody in the serum and mucosal secretions were determined. OVA+KML-C-treated mice showed high titers of IgA specific to CT in mucosal secretions. The antibody titers in the serum of OVA+KML-C-treated mice were comparable to those in the serum of OVA+CT-treated mice. When mice were immunized with OVA+KML-C or with CT alone and subsequently injected with OVA on the footpads after the primary immunization, they showed a more significant increase in delayed-type hypersensitivity reactions than when they were administered CT alone. These results suggest that KML-C is a potent immunoadjuvant that enhances both humoral and cellular immunity by the mucosal immune system.

To examine effects of oriental pharmaceutical preparations on immunity, four of such preparations which are currently being used were examined. After their fluid extracts were injected intraperitoneally to ICR mice, the counts of total cell number, PMN and macrophage in the peritoneal cavity were made by using non-specific esterase staining method, and plaque-forming cells (PFC) were measured by using the modified method of Cunningham and Jerne. The results showed that 'Bo-Jung-Ik-Ki-Tang', 'Ih-Jung-Tang', 'Ohn-Kyeong-Tang' and 'Ke-Ji-Bok-Ryeong-Hwan-Ka-Dae-Hwang' increased both the macrophages and the total cells of the peritoneal cavity and that these preparations increased the number of PFC in the spleen. Therefore the data indicate that they potentiate both of the cell­mediated and humoral immunities in the mice.
