The purpose of this study was to identify the Effect of Hand Reflexology on Saeng-chi of physiologic, emotional & motivational responses and Immunity in ESRD patients who received hemodialysis in two general hospital from June to September. 2001 A two group quasi-experimental research with pre and post test design was used. The number of participants in the experimental group was 23, and in the control group, 20 The Hand Reflexology Intervention was developed by the researcher based on hand reflexology by Carter & Weber and Chi-massage by Chia. The Hand Reflexology was applied to both hands for 10 minutes per day. and 5 days by 5 times. To evaluate the effects of the program, Pre and Post evaluations were done. In the physiologic response, the PR was decreased at the 1st times post treatment and at the 5th. In addition BP was decreased at the 1st time, but not the 5th. After 5 treatments, there were significant increase in Hb and significant decreases in the BUN and Cr. levels in the experimental group. In the emotional and motivational responses, there were significant increases in vigor, mood, uplifts and self care agency scores in the experimental group, but there was no significant difference in the Rosenberg's self esteem score. In the experimental group, significantly increased CD4, and h/s ratios were found, also NK cells were significantly decreased, and there was a decrease in the CD8. However, no significant differences between groups were observed. There were significant increases in CD32, CD33, CD34 in the experimental group. The self care agency score correlated negatively with the CD8. From the above results, Hand Reflexology is shown to be an effective mind-body nursing intervention for enhancing Saeng-chi responses and affecting some of the immune responses. However, Immune cell activation and differentiation with hand reflexology will be achieved with future study.

In this study, the marine medaka Oryzias javanicus was exposed to two concentrations of non-toxin-producing red tide dinoflagellate C. polykrikoides (1,000 and 2,000 cells ml^-1) for 96 h, and the time-course biochemical responses of antioxidant and immunity parameters were analyzed in the liver tissue. Significant ichthyotoxicity with increasing cell concentrations of C. polykrikoides and exposure period was observed for 96 h. Opercular respiratory rate was lowered in marine medaka exposed to 2,000 cells ml^-1 of C. polykrikoides. Intracellular malondialdehyde (MDA) content significantly elevated in response to both cell concentrations. In the case of glutathione (GSH) content, the levels were significantly elevated by 1,000 cells ml^-1 of C. polykrikoides, but the contents significantly depleted upon exposure to 2,000 cells ml^-1 of C. polykrikoides. Similarly, enzymatic activities of catalase (CAT) and superoxide dismutase (SOD) were increased by 1,000 cells ml^-1 of C. polykrikoides, whereas their activities were lowered by 2,000 cells ml^-1 of C. polykrikoides. Analysis of the two immunity parameters, alternative complement pathway and lysozyme, showed significantly lowered activities in 2,000 cells ml^-1 of C. polykrikoides-exposed liver tissue. These biochemical effects of C. polykrikoides on marine medaka would be helpful for understanding its acute effects in marine fish.

To study the immunity of the buffalo mammary gland during involution and around parturition and compare it with the mastitic mammary gland, milk samples were collected from 9 Murrah buffaloes during the above critical periods. SCC of buffalo milk increased significantly (p<0.01) by day 21 of involution and one week prepartum. SCC was significantly higher around parturition but became normal at 14 days postpartum. Phagocytic activity (PA) and phagocytic index (PI) of the buffalo milk neutrophils decreased as the duration of the dry period increased. Elevated levels of immunoglobulins at calving improved the PA and PI, but the lowest PA of 18.8% and PI of 1.75 were recorded at 7 days postpartum. Buffaloes suffering from clinical mastitis had PA of 12.3% and PI of 1.46 that increased significantly (p<0.01) on the third day of treatment. Distance of teat from ground level was found to be minimum at one week before parturition. The investigation showed that in vitro phagocytic activity of buffalo neutrophils was weakest at one week postpartum.

본 연구는 사료 중 크릴밀이 브로일러의 비장세포와 PBMC의 증식도에 미치는 영향을 조사하였다. 2주령 비장세포 증식도는 사료 중 크릴의 함량에 따라 증가하나, LPS주입으로 감소하였다. 콘카나발린 A(Con A) 첨가는 급여사료나 LPS 자극에 관계없이 증식도를 증가시켰다. 21일령 브로일러 비장세포의 증식도는 사료 중 크릴의 함량에 따라 높아졌다. LPS 스트레스로부터 회복중인 브로일러 비장세포의 증식도는 낮았다. 21일령에 PBMC의 증식도는 사료 중 크릴의 영향이 없었으나, LPS 자극에서 회복중인 브로일러의 증식도는 높아졌다. Con A 첨가는 급여사료나 LPS 자극에 관계없이 PBMC의 증식도를 높였다. 본 성적은 사료 중 크릴밀 첨가가 브로일러 비장세포 및 PBMC 증식에 영향을 미친다는 것을 나타낸다.

This study investigated the physiological effects of a diet containing calcium oxide (CaO) on the olive flounder, Paralichthys olivaceus. The results indicate that the amount of calcium in the blood was higher in the calcium group compared with the controls. The aspartate amino transferase (AST) and alanine amino transferase (ALT) levels were lower in the calcium group, while lysozyme activity was higher in the calcium group. Histologically, fish in the calcium group had more hepatocytes in the liver and more intact scales. In addition, an attack experiment using Vibrio anguillarum (KCTC-2711) and Edwardsiella tarda (KCTC-3657) showed that the survival was higher in the calcium group compared with the controls. These results suggest that feeding fish CaO when they require it, such as during periods of gonadal maturation and rapid growth, will increase their immunity and resistance to pathogens.

The signal transducer and activator of transcription (STAT)1 is a cytoplasmic-transcription factor that is phosphorylated by Janus kinases (Jak) in response to interferon $\gamma$ (IFN-$\gamma$). The phosphorylated STAT1 translocates to the nucleus, where it turns on specific sets of IFN-$\gamma$-inducible genes, such as the interferon regulatory factor (IRF)-1. We show here that gamma irradiation reduces the IFN-$\gamma$ mRNA expression. The inhibition of the STAT1 phosphorylation and the IRF-1 expression by gamma irradiation was also observed. In contrast, the mRNA levels of IL-5 and transcription factor GATA-3 were slightly induced by gamma irradiation when compared to the non-irradiated sample. Furthermore, we detected the inhibition of cell-mediated immunity by gamma irradiation in the allogenic-mixed lymphocytes' reaction (MLR). These results postulate that gamma irradiation induces the polarized-Th2 response and interferes with STAT1 signals, thereby causing the immunosuppression of the Th1 response.

The levels of maternal immunity enhancing factor(MIEF), which is an immunomodulatory protein identified from bovine colostrum, were determined by indirect competitive enzyme-linked immunosorbent assay(ELISA) for the colostrum and normal milk collected during the first two weeks of lactation. The mean concentration of MIEF in the colostrum of the first day of lactation was $109\;{\mu}g/ml$, and fell from the third day of lactation to $3{\sim}4\;{\mu}g/ml$. The molecular weight of the purified MIEF determined by reducing SDS-PAGE and TSK G2000SW column chromatography was 22,000 and 24,000 daltons, respectively, showing that MIEF is a monomeric peptide in its native form. To examine the capacity of MIEF to induce differentiation of B Lymphocytes, human tonsillar Iymphocytes were cultured in the presence of different concentrations of MIEF, and then antibody secreting cells were enumerated by enzyme-linked immunospot(ELISPOT) assay. When added to cultures of human tonsillar Lymphocytes, MIEF induced differentiation of resting B Iymphocyte to antibody secreting plasma cells as efficiently as LPS.

Inflammation is a pathophysiological response to infection or tissue damage during which high levels of reactive oxygen and nitrogen species are produced by phagocytes to kill microorganisms. Reactive oxygen and nitrogen species serve also in the complex regulation of inflammatory processes. Recently, it has been proposed that peroxiredoxins may play key roles in innate immunity and inflammation. Indeed, peroxiredoxins are evolutionarily conserved peroxidases able to reduce, with high rate constants, hydrogen peroxide, alkyl hydroperoxides and peroxynitrite which are generated during inflammation. In this minireview, we point out different possible roles of peroxiredoxins during inflammatory processes such as cytoprotective enzymes against oxidative stress, modulators of redox signaling, and extracellular pathogen- or damage-associated molecular patterns. A better understanding of peroxiredoxin functions in inflammation could lead to the discovery of new therapeutic targets.

Interferon-${\gamma}$-inducible protein 10 (IP-10), also known as chemokine C-X-C motif ligand (CXCL) 10, is closely associated with antiviral immunity and the progression of chronic hepatitis B (CHB). However, the value of baseline serological and histological IP-10 expression levels in predicting the efficacy of the antiviral response to nucleoside/nucleotide analogues (NAs) is still unknown. In our research, intrahepatic and peripheral IP-10 expression levels were systemically examined before and after treatment with entecavir (ETV). Baseline serological and histological IP-10 expression levels were significantly increased in patients with CHB, particularly in patients with higher degrees of liver inflammation and liver fibrosis. Moreover, higher baseline intrahepatic IP-10 levels indicated better prognoses in patients with CHB after entecavir therapy. The baseline IP-10 level was also positively associated with several clinical parameters, including baseline levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatitis B virus (HBV) DNA, and hepatitis B surface antigen (HBsAg), and with the decrease in HBsAg levels after treatment. In addition, monocyte-derived IP-10 was expressed at higher levels in patients with CHB than in patients with liver cirrhosis (LC) and healthy controls (HC). According to the results of our in vitro experiments, IP-10 directly promoted hepatocyte apoptosis. Based on these findings, baseline serological and histological IP-10 levels might predict CHB severity and the decrease in HBsAg levels after entecavir therapy.
