Objective: The pathogenesis of endometriosis is generally accepted that retrograde menstruation and alterations in the local pelvic immune environment. This study was performed to help elucidate what kind of role various cytokines might play in the pathogenesis of endometriosis. Method: Concentrations of peritoneal fluid cytokines were compared in 7 women with normal pelvic finding and 23 women with endometriosis by enzyme-linked immunosorbent assay(ELISA). The patterns of cytokine mRNA expression in 8 ovarian endometrioma and 12 superficial pelvic endometriosis lesions were investigated by reverse transcription-polymerase chain reaction(RT-PCR) amplification method. Result: Both IL-6 and IL-10 levels in peritoneal fluid specimens with endometriosis tended to be higher than normal. However, there were no significant differences between peritoneal fluid concentrations of IFN-γ, TNF-α, IL-1β, and IL-5 of women with and without endometriosis. The levels of IL-6 and IL-10 were significantly higher in peritoneal fluid of women with severe endometriosis compared to women with mild endometriosis. IL-1β mRNA was expressed in all of 8 deep and 12 superficial endometriosis lesions. IL-5 and IL-6 mRNA were expressed in only two black lesions respectively, however, both were not expressed in the all deep lesions. Expressions of IL-10 mRNA occurred in one red and one black lesion while this was expressed in only one of the deep lesions. TNF-α mRNA was expressed in one red and one black lesion of 12 superficial lesions compared with four of the deep lesions. There was the difference between kinds of increased cytokines in the peritoneal fluid and those of expressed cytokines in the endometriotic lesions of patients with endometriosis. Conclusion: This study supports the concept that local immunologic factors may be important in the pathogenesis and pathophysiology of endometriosis. The pattern of cytokine mRNA expression of endometriotic lesions would seem to indicate that proinflammatory cytokines such as IL-1β and TNF-α are responsible for the development or progression of endometriosis.

The inflammatory reaction to tissue damage during surgery may induce central sensitization followed by hyperalgesia. Previous studies suggest that central sensitization is related to N-methyl-D-aspartate (NMDA) receptor activation, which can be blocked with NMDA antagonist, ketamine. Thus, we compared the effect of preoperative intravenous and epidural low doses of ketamine with placebo on serum interleukin-6 (IL-6) level and postoperative pain. ASA class I and II women scheduled for C-sections received intravenous ketamine 0.15mg/kg(group 2) or placebo(group 1), or epidural ketamine(0.15 mg/kg) before the operation. IL-6 levels were measured before and during the operation, and 8, 24, and 48 hrs after the operation. Visual Analogue Scales(VAS) and Verbal Ration Scales(VRS) were measured at 8, 24, and 48 hrs after the operation. Serum IL-6 levels at 8, 24, and 48 hrs after the operation were significantly lower in the intravenous ketamine and epidural ketamine groups than in the control group. VAS at 8 hrs and 48 hrs after the operation were significantly lower in the epidural ketamine group. VAS at 8 hrs and 48 hrs after the operation were significantly lower in the epidural ketamine group than in the control and intravenous ketamine groups. In conclusion, in the preoperative intravenous and epidural administration of low doses(0.15mg/kg) of ketamine, both are effective in reducing postoperative IL-6 levels. Epidural Ketamine is more effective than intravenous ketamine in postoperative pain control.

본 연구는 들깨 새싹 추출물의 항산화, 항염증 및 항부종에 대한 효과를 조사하였다. 들깨 새싹 추출물은 DPPH와 ABTS 라디칼을 효과적으로 제거하는 항산화 활성이 우수하였다. 또한 들깨 새싹 추출물은 활성화된 설치류 유래 대식세포주인 RAW 264.7세포와 인간 유래 HMC-1 세포의 TNF-α와 IL-1β를 효과적으로 억제하였다. 더욱이 마우스의 귀와 발 부종을 억제하는 우수한 효과가 있었다. 이러한 결과는 들깨 새싹 추출물은 항산화제로 사용될 수 있을 뿐만 아니라 항염증과 항부종에 효과적인 물질이라는 것을 제시해주었다. 이와 관련된 들깨 새싹 추출물의 기능성에 대해서는 앞으로 분자생화학적 수준에서 더 연구해야할 필요성이 있는 것으로 사료된다. We investigated the effects of an ethanol extract from Perilla frutescens sprouts (PFSE) as an antioxidant, and its effects on edema and inflammation in RAW 264.7 cells and HMC-1 cells. The antioxidant activities (DPPH and ABTS radical scavenging) of PFSE were similar to those of butylated hydroxytoluene (BHT) and (±)-6-hydroxy-2,5,7,8- tetramethylchromane-2-carboxylic acid (Trolox). We also investigated the anti-inflammatory effects of PFSE on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and HMC-1 cells stimulated with phorbol 12-myristate 13-acetate (PMA) with the calcium ionophore A23187. TNF-α and IL-1β production, which had been increased by treatment with LPS or PMA plus A23187, were significantly inhibited by PFSE in a dose-dependent manner. Furthermore, PFSE significantly reduced the xylene-induced ear edema and the carrageenan-induced paw edema of ICR mice in a dosedependent manner. The effects of PFSE (200 mg/kg) in reducing ear and paw edema were similar to those of aspirin (50mg/kg). These results suggest that PFSE can be potentially used as a medicine for treating oxidative stress, an edematous and inflammatory disease.

백혈병 마우스 모델의 동종골수이식에서 활성화된 자연살해세포들의 보충이 이식편대백혈병효과와 이식편대숙주반응에 미치는 영향

엄현석,한치화,박수정,김소연,정낙균,정대철,진종률,최일봉,양형모,서영훈,송현근,최인표,민우성,김춘추 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.1

배경: 백혈병에서 동종골수이식 (allogeneic bone marrow transplantation)의 성공적 치료 효과를 얻기 위해서는 이식편대숙주반응 (graft-versus-host disease, GVHD) 발생의 극복과 재발의 방지가 중요한 과제이다. 골수를 역류원심성 세포분리 (counterflow centrifugal elutriation, CCE) 방법으로 분리하여 얻은 rotor off (R/O) 세포분획은 T 세포의 수는 적지만 조혈모세포들을 다량 포함하고 있어 동종골수이식에서 주조직적합복합체 (major histocompatibility complex, MHC) 차이를 극복할 수 있고, 이식편의 생착 성공과 GVHD 발생 예방에 효과적이다. 그러나 골수로부터 T 세포를 제거하면 백혈병세포를 공격하는 이식편대백혈병 (graft-versus-leukemia, GVL) 효과가 감소되기 때문에 백혈병 재발의 빈도가 높다. 자연살해세포 (natural killer cell, NK cell)의 보충 첨가는 동종골수이식 후 GVHD 발생을 줄이면서 충분한 GVL 효과를 얻을 수가 있다. 따라서 저자는 분리 후 IL-2로 활성화시킨 NK 세포들을 골수 R/O 세포분획과 함께 백혈병 마우스 모델에 동종이식함으로써 GVHD와 GVL에 미치는 효과를 관찰하였다. 방법: Balb/c (H-2^(d)) 마우스에서 유래된 A20 (murine B-lymphoma/leukemia cell line, H-2^(d)) 백혈병 세포를 이식 2 일 전에 Balb/c 마우스에 주입하고, 치사량의 전신 방사선을 조사한 직후에 Balb/c 또는 C57BL/6 (H-2^(b)) 마우스의 골수 R/O 세포분획을 꼬리정맥을 통하여 주입하였다. 이들은 모두 이식 후 6-8 주 이내에 사망하였다. 동종이식의 대조군 (n=9)에는 1 × 10^(7)의 R/O 세포분획만을 주입하였고, 실험군 (n=9)에는 C57BL/6 마우스의 비장세포들로부터 단클론항체들을 이용한 negative selection방법으로 분리한 후 IL-2로 활성화된 5 × 10^(5)의 NK 세포분획을 1 × 10^(7)의 R/O 세포분획과 함께 주입하였다. GVL 효과의 판정은 이식 후 14 일과 28 일 째 되는 날 마우스에서 골수, 비장, 간 등을 얻어 백혈병 세포들의 침윤을 조직학적으로 관찰하였으며, GVHD의 정도는 육안적 관찰법으로 평가하였다. 결과: R/O 세포분획만을 이식한 대조군의 골수, 비장, 그리고 간 조직에서는 A20 백혈병 세포의 침윤이 각각 89% (8/9), 78% (7/9)와 22% (2/9)에서 관찰되었고, R/O 세포분획과 NK 세포분획을 함께 이식한 실험군에서는 비장과 간을 제외한 골수에서만 89% (8/9)에서 A20 백혈병 세포의 침윤이 관찰되어 두 군 사이에 장기별 분포의 차이를 볼 수 있었다 (P= 0.0001). 한편 GVHD는 두 군 모두에서 경하게 나타나서 유의한 차이는 없었다. 또한 생착 부전으로 사망한 마우스는 없었다. 결론: CCE를 이용하여 T 세포를 제거한 동종골수이식에서 NK 세포의 보충은 GVHD의 악화는 일으키지 않으면서, 백혈병의 진행을 억제하는 GVL 효과를 얻을 수 있었다. Background: Allogeneic bone marrow transplantation (BMT) with T cell-depleted marrow accompanies engraftment failure and relapse of leukemia by a loss of the graft-versus-leukemia (GVL) effect frequently, while it can prevent GVHD. Supplement of NK cells could prevent GVHD and enhance GVL effect in several murine allogeneis BMT models Roter off (R/O) cell fraction obtained by counterflow centriation elutriatio (CCO) contains small number of T cells and many hematopoietic stem cells. The aim of this study was to determine the effect of R/O cell fraction supplemented with IL-2 activated NK cells on GVL and GVHD within the leukemic mouse BMT model. Methods: Inoculation of A20 (H-2d, murine B-lymphoma/leukemia, Balb/c origin) cells into Balb/c mice via the tail vein 2 days prior to lethal total body irradiation (TBI) and infusion of the Balb/c BM or C57BL/6 (H-2b) R/O fraction were performed. It resulted in 100% mortality within 6 to 8 weeks. The irradiated mice in the control group were injected with 1 × 107 R/O cell fraction alone (n=9) and in the experimental group mice were injected with 1 × 107 R/O cell fraction plus 5 × 105 negatively selected IL-2 activated NK cell fractions of the spleens via the tail vein (n=9). On day 14 and 28 after BMT, the bone marrows, spleens, and livers of mice were harvested for histopathologic analysis of the infiltrations of leukemic cells. We then evaluated the GVHD within the mice. Results: A histopathologic study of the recipients receiving R/O fraction alone showed infiltration of leukemic cells, 89% (8/9) in bone marrows, 78% (7/8) in spleens, and 22% (2/9) in livers. The experimental group of mice showed only the infiltration of leukemic cells 89% (8/9) in bone marrows, not in spleens and livers. There were the organ differences of the leukemic cells infiltrations between the two groups (P=0.0001). There were no obvious differences in the GVHD scores between these two groups, and severe GVHD was not observed. There was no engraftment failure among groups. Conclusion: Thus, our findings suggest that R/O cell fraction obtained by CCE and supplemented with NK cells can promote GVL effect without mediating clinically overt GVHD in allogeneic BMT of mouse leukemia.

Aspiration of a foreign body in the airway is common cause of sudden obstructive breathing, crouping cough, hoarseness, and wheezing. Especially that caused serious problem in case of the young children. A past history of foreign body aspiration is itself an indication for bronchoscopic examination of the airway, because some children with aspirated foreign bodies are without symptoms and chest X-ray films may not show abnormalities. So the anesthesiologist should take a notice of removing foreign body in the anesthetic procedure. The author have experienced 36 cases removal of foreign bodies in the airway under general anesthesia from July, 1982 to January, 1996 in Chunan Hospital, College of Medicine, Soonchunhyang University. The results were as follows 1) Among the 36 cases, 25 cases(69.7%) were under the age of 5. The ratio of male and female was 1.8 : 1. 2) In duration of lodgement, there was most frequent within one day in 15 cases(41.7%) and the longest duration was 20 days. 3) The most common symptom, sign and auscultation finding were cough 19 cases(52.8%). chest retractions 7 cases(19.4%) and decreased breathing sound 20 cases(55.6%) 4) Abnormalities in the chest X-ray were found in 15 cases(41.7%) among 36 cases. 5) Vegetable foreign bodies, expecially peanut were the most common airway foreign body(28.7%), followed by plastic foreign body(14.4%) and mucous plug(11.3%). 6) The foreign body involved the right bronchus 16 cases(45.7), left bronchus 10 cases(28.6%), trachea 5 cases(14.3%), and larynx 4 cases(11.4%). 7) Foreign body induced complications occurred in 9 cases(25.0%); pneumonia 8 cases and pneumomediastinum 1 case, and all of postoperative complication was pneumonia(25.0%). 8) 34 foreign objects(94.4%) were removed by endoscopy but tracheostomy was required in two patients.

The present study was conducted to predict shelf life of pasteurized milk with analysis of volatile compounds and sensory evaluation of milk to growth of psychrotrophic bacteria. Pseudomonas fluorescens KFRI 00194 inoculated concentration of 10^4 cfu/㎖ to observe of changes on sensory evaluation and volatile compounds of pasteurized milk. The results obtained in these experiments were summarized as follows; The psychrotrophic bacteria number at 4℃ were increased 6.39×10 exp(4)cfu/㎖ until first day and 2.20×10 exp(6)cfu/㎖, 1.17×10 exp(7)cfu/㎖ after 5 and 10days, respectively. The volatile compounds were shown the decreasing tendancies in acetaldehyde, ethanol depending on storage days, especially ethanol contents were significantly decreased between 5 and 10days storage(P<0.05). Diacetyl, 2-heptanone, 2-butanone and 3-methyl-1-butanol were shown the increasing tendencies of contents. Diacetyl, 2-heptanone and 2-butanone were significantly increased between 5 and 10days, 1 and 5days, 5 and 10days and 1 and 5days, respectively(P<0.05). However, 3-methyl-1-butanol was shown a increasing tendancy depending on storage days but the significantly different was not recognized. The changes of sensory evaluation were rapidly decrease from 6.8point first day to 4.2point after 10days and the decrease of organoleptic acceptability was significantly different recognized(P<0.05), excepted of 1 and 2days. The organoleptic acceptability according to increasing of psychrotrophic bacteria numbers were decreased. The organoleptic acceptability depending on changes of volatile compounds were shown to a conversed correlation coefficient with the exception of acetaldehyde and acetone. Especially, 2-heptanone, 2butanone and 3-methyl-1-butanol were gradually decreased of acceptability by the contents.

Although various derivatives of caffeic acid have been reported to possess a wide variety of biological activities such as protection of neuronal cells against excitotoxicity, the biological activity of 1-docosanoyl cafferate (DC) has not been examined. The objective of the present study was to evaluate the anti-inflammatory effects of DC, isolated from the stem bark of Rhus verniciflua, on lipopoly-saccharide (LPS)-stimulated BV2 microglial cells. Pretreatment of cells with DC significantly attenuated LPS-induced NO production, and mRNA and protein expression of iNOS in a concentration-dependent manner. DC also significantly suppressed LPS-induced release of cytokines such as TNF-${\alpha}$ and IL-$1{\beta}$. Consistent with the decrease in cytokine release, DC dose-dependently and significantly attenuated LPS-induced mRNA expression of these cytokines. Furthermore, DC significantly suppressed LPS-induced degradation of IKB, which retains NF-kB in the cytoplasm. Therefore, nuclear translocation of NF-kB induced by LPS stimulation was significantly suppressed with DC pretreatment. Taken together, the present study suggests that DC exerts its anti-inflammatory activity through the suppression of NF-kB translocation to the nucleus.
