The purpose of this study is to determine the changes of cytokines and immune cells in blood in castrated Hanwoo. The cytokine production and the number of immune cells were determined by collecting blood from jugular vein before castration and on 1, 7, and 28 days then after. Results of the hematological test showed that the number of leukocyte tend to increase after castration, and it significantly decreased on day 7 and day 28 (P<0.05). Lymphocytes decreased significantly on day 1 and 7 (P<0.05), and then recovered as in neutrophils on day 28. The levels of serum testosterone, TNF-a, IL-6, and anti-inflammatory IL-10 significantly decreased (P<0.05) after castration. There was also a decrease in IL-2, $IFN-{\gamma}$, and IL-4 but showed no significant difference when compared to intact ones. These results suggest that testosterone-deficiency does not affect the number of immune cells in blood, but has a close relationship with cytokine production.

Objectives : The aim of this study was to evaluate whether herb mixture extract (HME) would affect allergic contact dermatitis induced by 1-chloro-2,4-dinitro-chlorobenzene (DNCB) in mice. For this, the level of blood IgE was identified. To evaluate anti-inflammatory effect of HME, we tested HMC-1 cells stimulated by PMA+A231867. Methods : In order to evaluate allergic contact dermatitis effects we observed HME on contact-hypersensitive skin of Balb/cmice induced by 0.5% DNCB and measured concentration of IgE in blood of Balb/c mice. In order to evaluate anti-inflammatory effect of cytokine expression we used the method of enzyme-linked immunosorbent assay. Results : We confirmed deep wounds, erosions, progress of keratinization and drop out of dead skin cells from Balb/c mice induced by 0.5% DNCB. We also observed a remarkable decrease in symptoms of atopic dermatitis in the group that received injection of 200mg/kg HME. In addition, in the measurement outcome for IgE concentration in blood, we confirmed that IgE concentration was increased by treatment with DNCB only, while it was markedly decreased by treatment with HME. We confirmed that cytokine expression decreased through enzyme-linked immunosorbent assay and pERK, pJNK, and pp38 also decreased through western blot test Conclusions : According to the above results, HME has some effect on alleviating symptoms of allergic contact dermatitis and has anti-inflammatory effects.

Suppression of cellular immunity is the host responses to surgical stress. When the body is exposed to surgical stress, decreased immunocyte function is one of the surgical stress-induced biologic responses. In all patients exposed to the surgical stress, peripheral blood lymphocyte numbers and function were suppressed until at least 2 weeks postoperatively. This immunosuppression was mainly due to a decrease of helper-inducer T cells, cytotoxic T cells, natural killer cells, and an increase of suppressor T cells. The blood levels of interleukin-6(IL-6) cytokine increase in response to surgical stress and cause an increase of so-called acute phase reactants, including C-reactive protein(CRP). In the previously damaged patients group, expected to early stress expose, immunosuppression was more developed than other normal groups. Cellular immunosuppression by surgical stress was mainly due to an increase of lymphocyte subsets that depress cellular immunity coupled with a decrease of the subsets that promote it. Overproduction of CRP in response to surgical stress may play an important role in the development of immunosuppression.

Purpose: To provide the basic method for physical therapy to contribute to early stage treatment of a burned patients. We investigated whether or not carbon arc lamp treatment and low level laser one among various laser treatments have the effect of reducing Cytokine, and to elucidate the effect of carbon arc lamp treatment and laser one. Methods: The 6-week old BALB/c types of 92 mice were used for the experimental test, and they were burned with $100^{\circ}C$ water, they were divided into 4 groups in accordance with the method of treatment respectively. And the blood and the tissue from the subject of each group were extracted and analyzed each time after they were cured for 3, 6, 9 days. For the analysis of the results, SPSS statistical program was used in this study. Results: The quantity of $TNF-{\alpha}$ and $IL-1{\beta}$ within the blood of a burned mouse increased more than that of a normal mouse(p<0.01). In only a burned mouse, carbon arc lamp treatment gave the effect on the decrease of $TNF-{\alpha}$ thickness the 6th day to the 9th day(p<0.01). $IL-1{\beta}$ quantity was more decreased than that of control group around the 6th day. In comparison with only a control group, low level laser treatment has more significant effect in decreasing the quantity of $TNF-{\alpha}$ a and $IL-1{\beta}$ than the two different methods(p<0.01). In case that the two treatment methods, carbon arc lamp treatment and low level laser, were executed together, there was the effect of decreasing $TNF-{\alpha}$ until the 6th day(p<0.01). Conclusion: Both low level laser treatment and carbon arc lamp one would be able to have an effect on the inflammation inhibition of burned patients and tissues reproduction. However, it must be also considered for the two treatments to be done at the same time.

The study was conducted to correlate the periparturient immune status in terms of neutrophil functions and cytokine expression in peripheral blood mononuclear cell culture with impending postpartum reproductive disorders in buffaloes. Forty pregnant buffaloes were observed for occurrence of postpartum reproductive disorders (PRD), i.e., metritis, endometritis and delayed uterine involution etc., during one week prepartum to four weeks postpartum period. A representative number (n = 6) of buffaloes that did not develop any PRD were included in group I (healthy, control), while the animals which experienced PRD were assigned into group II (PRD, n = 8). The blood samples were collected at weekly interval from one week prepartum to four weeks postpartum period considering the day of calving as 'd 0'. Differential leucocytes counts, superoxide and hydrogen peroxide production activity in isolated neutrophils and the mRNA expression profile of cytokines i.e., IL-2, IL-4 and IFN-${\gamma}$ in PBMC culture were studied in all the samples. A higher total leucocytes, neutrophil and band cells count along with impaired neutrophil functions i.e., lowered level of production of superoxide and hydrogen peroxide before parturition and during early postpartum period were observed in buffaloes developing PRD. Further, a lower expression of IL-2, IFN-${\gamma}$ and IL-4 mRNA in PBMC culture was observed at calving in buffaloes that subsequently developed PRD at later postpartum. Thus, suppression in neutrophil function and cytokine expression at prepartum to early postpartum period predisposes the buffaloes to develop postpartum reproductive disorders. Hence, monitoring of neutrophils function and cytokine expression profile would be effective to predict certain reproductive disorders at late pregnancy or immediately after parturition in buffaloes. In future, this may be a novel approach for determining suitable management and therapeutic decisions for prevention of commonly occurring reproductive disorders in farm animals.

The study was designed to investigate the effects of Leonuri herba extract (LHE) on the change of regional cerebral blood flow (rCBT and cytokines production (IL-1${\beta}$, TNF-${\alpha}$, IL-10, TGF-${\beta}$) in ischemic rats. The results were as follows : The rCBF was significantly and stably increased by LHE (10 mg/kg, i.p.) during the period of cerebral reperfusion, which contrasted with the findings of rapid and marked increase in control group. In cytokine production of serum by drawing from femoral arterial blood at 1 hr after middle cerebral arterial occlusion, experimental group (LHE 10 mg/kg treated group) was significantly decreased IL-l${\beta}$ production, and increased TGF-${\beta}$ production compared with control group. In cytokine production of serum by drawing from femoral arterial blood at 1 hr after reperfusion, experimental group was significantly decreased IL-1${\beta}$ production compared with control group. IL-10 and TGF-${\beta}$ production of sample group were significantly increased compared with control group. These results suggested that LHE was significantly and stably increased regional cerebral blood flow by inhibited IL-1${\beta}$ production, and accelerated IL-10 and TGF-${\beta}$ production.

1. 연구배경 및 목적 사상의학(四象醫學)에서 열다한소탕(熱多寒少湯)은 태음인(太陰人)의 뇌경색증 급성기에 매우 빈번하게 사용되는 처방 중 하나이다. 그래서 저자는 열다한소탕(熱多寒少湯) 투여에 따른 뇌경색증 환자의 면역계 특히 세포활성문질만계의 변화에 대해 연구하기로 하였다. 2. 방법 원광대학교 광주한방병원 사상의학과에 입원한 뇌경색증 한자 8인(남자 3명, 여자 5명)을 대상으로 하여, 내원 당시와 2-4주간의 열다한소탕 투여 후의 세포활설물질망계의 변화를 추적하였다. 또한 정상태음인의 말초혈액단핵구를 채취하여 리포다당체 처리시의 변화를 열다한소탕(熱多寒少湯) 전처리 유무에 따라 비교 분석하였다. 3. 결과 IL-2 혈장 농도는 정상 대조군보다 환자군에서 더 낮았다. $IFN-{\gamma}$의 경우 역시 정상 대조군보다 약간 낮았으나 통계학적 유의성은 없었다. IL-4, IL-6, IgE의 혈장중 수준은 정상 대조군에 비해 환자군에서 현저히 상승되어 있었다. 그러나, 2-4주간의 열다한소탕(熱多寒少湯) 투여후 $IFN-{\gamma}$, IL-2의 혈장 중 수준은 현저히 상승되었고, IL-4, IL-6, Ig E 수준은 현저히 억제되었다. 한편 정상 태음인의 말초혈액단핵구에 리포다당체 처리를 한 후 $IFN-{\gamma}$, IL-2, IL-6가 상승되었으나, 열다한소탕(熱多寒少湯) 전처리를 한 경우에서는 이들 물질의 생성이 유의하게 억제되었다.
