Zoster sine herpete (ZSH) is one of the atypical clinical manifestations of herpes zoster (HZ), which stems from infection and reactivation of the varicella-zoster virus (VZV) in the cranial nerve, spinal nerve, viscera, or autonomic nerve. Patients with ZSH display variable symptoms, such as neuralgia, however, different from HZ, ZSH show no zoster, which makes clinical diagnosis difficult. ZSH not only causes initial symptoms, such as neuropathic pain in the affected nerve, Bell palsy, and Ramsay Hunt syndrome, but also postherpetic neuralgia and fatal complications such as VZV encephalitis and stroke. The misdiagnosis of ZSH and tardy antiviral treatment may lead to severe ZSH sequelae. We review the publications related to ZSH, especially its diagnosis with VZV DNA and/or anti-VZV immunoglobulin (IgG and IgM). More work about ZSH, especially ZSH epidemiological survey and guidelines for its diagnosis and treatment, are needed because most of the present studies are case reports.

In this study, the immunomodulatory activity of oligopeptide (CP) derived from solid-state fermented cottonseed meal were investigated in immunosuppressed BALB/c mice models by treatment with cyclophosphamide (CY). Results indicated that oligopeptide increased the thymus and spleen indices of CY-treated mice. The count of plague forming cells (PFC) and the content of half serum hemolysis ($HC_{50}$) in immunosuppressive mice were restored to the normal level in CP-10 and CP-20 groups while the cytokines interleukin (IL)-2, IL-6, and tumor necrosis factor alpha (TNF-${\alpha}$) were increased significantly in CP-20 group. Similar increasing the immunoglobulin of IgG and IgM content in the serum of CP-10 group were also observed. These findings indicated that oligopeptide derived from solid-state fermented cottonseed meal had a strong immune-enhancing activity as well as a protective effect against immunosuppression induced by cyclophosphamide in mice.

Numerous physiological effects are attributed to conjugated linoleic acid(CLA). The purpose of this study is to consider these effects with respect to the cis-9, trans-11 and trans-10, cis-12 CLA isomer. Both isomers are natural products. The c9,t11-CLA isomer is the principal dietary form of CLA, but the concentrations of this isomer and the t10,c12-CLA Isomer in dairy products or beef vary depending on the diet fed to cows or steers, respectively. The influence of dietary CLA isomers on the immune response was examined, body weight and weight ratio of organ to body of Balb/C mice. Mice were divided into four groups of 8 mice. Balb/C mice were fed the experimental diets supplemented with 1% CLA (c9,t11-CLA isomer : t10,c12-CLA isomer = 2:3) (Group 1), 1% CLA (c9,t11-CLA isomer t10,c12-CLA isomer : 1:1) (Group 2), 1% safflower oil (Group 3) or nothing (Control) for 3 weeks. After 3 weeks, serum, gut lumen lavage, fat, liver, spleen and thymus were taken. Measurement of total immunoglobulin were executed using sandwich ELISA. Serum levels of IgA and IgM showed that group fed with t10,c12-CLA isomer significantly were higher than group fed with c9,tl1-CLA isomer. In addition serum level of IgG showed that group fed with t10,c9-CLA isomer significantly were lower than group fed with c9,tl1-CLA isomer. However, no significantly differences were observed in the serum IgE and secretory IgA. Weight ratio of spleen to body showed no significant differences. In weight ratio of liver and thymus to body, tl0,c9-CLA isomer significantly were respectively higher than group fed with c9,t11-CLA isomer. In weight ratio of fat to body, tl0,c9-CLA isomer significantly were respectively lower than group fed with c9,tl1-CLA isomer. In conclusion, t10,c12-CLA isomer produced a situation favorable for immunopotentiative effect and body composition. But it should be protected against hepatomegaly induced lipid accumulation in liver.

다이옥신계 TCDD에 노출된 흰쥐의 지질대사 및 면역관련 인자에 대하여 키토산 올리고머의 분자량에 따른 섭취효과를 알아보기 위해 Sprague-Dawley rat(수컷, 6주령)를 이용하여 TCDD를 40 ${\mu}g$/kg BW로 복강 내 주입하고 키토산 올리고머 분자량을 1000 이하, 1000~3000 및 5000~10000으로 수준을 달리하여 4% 첨가하고 3주간 실험하였다. 실험동물의 장기의 무게에서 간의 상대중량은 TCDD 투여군에서 모두 유의적으로 높았다. 뇌와 고환의 상대중량은 대조군과 TCDD 투여군에 비하여 TCDD 투여와 함께 키토산 올리고머를 섭취한 군에서 모두 현저히 증가하였다. 흉선의 상대중량은 대조군에 비하여 TCDD 투여군에서 모두 약 1/4 정도로 감소되었다. 혈액성분에서 적혈구의 수는 TCDD 투여에 의한 감소가 TCDD 투여와 함께 키토산 올리고머를 섭취한 군 모두에서 대조군 수준으로 증가되었고, 백혈구의 수와 헤모글로빈 및 헤마토크리트값은 TCDD 투여에 의한 감소가 TCDD 투여와 함께 키토산 올리고머의 분자량이 1000 이하인 것(COST)과 5000~10000인 것을 섭취한 군(COLT)에서 회복되는 경향을 보였다. 간 기능에 지표가 되는 효소인 혈청 GOT와 ALP는 대조군에 비하여 TCDD 투여군 모두에서 높은 경향을 보였다. 혈청 총콜레스테롤 및 HDL-콜레스테롤함량은 TCDD 투여에 의한 증가가 TCDD 투여와 함께 키토산 올리고머 분자량이 5000~10000인 것을 섭취한 군(COLT)에서 유의적으로 감소되어 콜레스테롤 억제효과가 나타났다. 간 지질에서는 총 지질과 콜레스테롤 및 중성지방이 유사한 경향으로 대조군에 비하여 TCDD 단독투여군에서 현저한 증가를 보여 지질축적이 되었는데 TCDD 투여와 함께 키토산 올리고머를 섭취한 군들에서 현저한 지질 억제효과를 내었다. 특히 TCDD투여와 함께 분자량 1000 이하의 키토산 올리고머를 섭취한 군(COST)이 TCDD 단독 투여 군에 비하여 간 콜레스테롤을 2/3 정도로, 간 중성지방을 1/2 정도로 뚜렷이 억제하였다. 변 중의 총 지질과 콜레스테롤함량은 TCDD 투여로 증가되는 경향이었고 TCDD 투여와 함께 키토산 올리고머 첨가한 군들에서는 TCDD군보다 대체로 낮은 경향이었다. 담즙산 배설은 대조군에 비하여 TCDD 투여군 모두에서 현저하게 낮았다. 간의 현미경적 관찰에서는 TCDD 투여에 의한 간세포의 지방구 침윤과 세포크기의 다양성, 간세포의 과염 색상과 공포변성이 TCDD 투여와 함께 키토산 올리고머를 섭취한 군 모두에서 현저하게 회복되었다. 혈청의 면역인자인 IgA와 IgM의 농도에서는 대조군과 TCDD 단독투여 군보다 TCDD 투여와 함께 키토산 올리고머의 분자량 5000~10000인 것을 섭취한 군(COLT)이 유의적으로 높은 농도를 나타내었다. 이와 같은 결과로 키토산 올리고머의 분자량이 1000 이하인 것은 혈구수의 회복과 간 지질억제에 효과적이었고, 분자량이 5000~10000인 것은 혈구수의 회복과 함께 혈청 콜레스테롤 저하 및 면역인자들 수준을 증가시키는 경향이 있었다. 특히 간의 조직병변이 키토산 올리고머 식이에 의해 정상으로 회복되는 경향을 관찰할 수 있었다. 그런데 키토산 올리고머의 분자량별 효과에 대하여는 앞으로 더 많은 연구가 필요한 것으로 사료된다.

This study was conducted to evaluate the effects of dietary supplementation of plant flavonoid (quercetin) on immune parameters, growth performance, and nutrient digestibility in growing pigs challenged with Escherichia coli lipopolysaccharide (LPS). A total of 40 crossbred ([Landrace × Yorkshire] × Duroc) growing pigs; initial body weight (BW) of 26.95 ± 1.26 kg were used in a six-week experimental trial. Pigs were randomly allocated into one of four treatment groups in a 2 × 2 factorial arrangement with the following factors; without LPS challenge and with LPS challenge (day 21) supplemented with or without 0.1% flavonoid according to BW (2 replicate pens per treatment with 2 gilts and 3 barrows per pen). The single-dose LPS (100 ug / kg BW) injection showed trends tended to be increased in interleukin-6 (IL-6) after 2 h and 6 h of challenge compared with unchallenged pigs. However, other measured immune indices (white blood cell, immunoglobulin G, lymphocyte, and tumor necrosis factor), growth performance, and nutrient digestibility were not significantly different between challenged and non-challenged animals. The supplementation of flavonoid significantly increased (p < 0.05) average daily gain (ADG) during day 0-21, tended to increase dry matter and nitrogen digestibility, significantly reduced IL-6, increased Ig-G and WBC concentrations and increased lymphocytes percentage regardless of LPS challenge.

Clinical and epidemiologic data point to a causal interrelationship between nutritional deficiency and infectious illness. Both are major contributors to childhood morbidity and mortality, particulary in underprivileged population groups. Protein-calorie malnutrition depress a variety of immune funtions. Delayed hypersensitivity and number of T-lymphocytes are consistently reduced. The interrelationship between nutritional status and immune response was studied in 80 children aged under 6 years. According to the anthropometric assessment based on weight for height for age, 36 children were classified as normal, 22 as morderate malnutrition, and 22 as severe malnutrition. The following determinations were made : hemeglobin, hematocrit, serum albumin, immunoglobulin G, complement 3, and WBC levels. Results indicate that levels of Hb, Hct, serum albumin, and C3 concentration were decreased in moderate and severe malnutrition children. However, levels of IgG and WBC were not affected by the nutritional status. It is suggested that nutritional status has more profound effects on complement system than humoral immunity.

To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status we surveyed 169 persons 90 females and 79 males aged 40∼69 years from June 7 to June 14 1997 in Whachon area Kang-Won Do Korea. For this purpose we investigated Helicobacter pylori infec-tion and identified the effect of sex age, smoking alcohol consumption economic status occupation life-style and food intake on Helicobacter phlori infection. Helicobacter pylori status was evaluated using an en-zyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicob-acter pylori infection was present in 66.3% of total subjects namely 67.7% of female and 64.4% of male and its prevalence increased with smoking low education level and low monthly income. Energy total protein calcium and vitamin C intakes in the negative Helicobacgter phlori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the helicobacter pylori negative group than in the positive group.

Objective: The root bark of Ulmus davidiana var. Japonica (Ulmi Radicis cortex, URC) is a medicinal herb used for promoting diuresis and treating dampness. In Korea, URC has long been used as an efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we used 1-fluoro-2,4-dinitrofluorobenzene (DNFB)-induced contact dermatitis (CD) mouse model to investigate the anti-allergic and the anti-inflammatory effects of URC on skin lesion, histopathological changes and specific antibody production. Results: URC treatment, 10 mg/mL, effectively inhibited skin lesions induced by repeated paintings with DNFB. In the histopathological observation, topical application of URC inhibited spongiosis. In addition, URC lowered the production levels of total immunoglobulin and IgG2a in serum. Conclusion: These data indicate that URC has an anti-inflammatory effect that produces an improvement of skin lesions in CD mice.

Here, we demonstrate surface functionalization of Au chips with 4-(carboxymethyl)aniline (CMA) and amine-terminated polyamidoamine (PAMAM) dendrimers for immobilization of antibodies on the Au surfaces. Use of the functionalization strategy led to high surface density of the immobilized antibodies on the Au chips. Specifically, we found that the functionalization of Au chips with CMA and amine-terminated $6^{th}$ generation PAMAM dendrimers allowed immobilization of immunoglobulin (IgG) antibodies with high surface density, which is 5 times higher than that obtained with Au surfaces functionalized with CMA and ethylenediamine.
