  • Objectives: Angiocentric T-cell lymphoma of the head and neck is an angiocentric and angiodestructive lymphoreticular proliferative disorder. It has been treated with various treatment modalities, but its prognosis is poor and the treatment modality is controversial. We performed this study to suggest a treatment modality with improved results. Materials and Methods: We studied 40 cases of pathologically confirmed angiocentric T-cell lymphoma from July 1984 to December 1996, 35 cases of which showed complete response after initial treatment. All the patients were divided into two groups according to treatment modality. 15 cases received radiotherapy alone (Group I) and 20 cases received radiotherapy after five cycles of CHOP-Bleo chemotherapy(Group II). We analyzed the subsites of tumor, stage, treatment modality and treatment outcome and causes of failure for each group, and compared the three-year no evidence of disease(NED) between the two groups. Results: The three-year NED of a combined chemoradiotherapy was higher than that of a radiotherapy alone (p=0.0478). The three-year NED according to groups and stage were as follows: Group I=6/15(40.0%), stage IE=5/10(50.0%), stage IIE=1/5(20%), Group II=13/20(65.0%), stage IE=9/13(69.2%), stage IIE=4/7(57.1%). Radiotherapy alone is not well effective for the nasal cavity lymphoma extended to paranasal sinus and the palate. Conclusion: We are unable to provide clear guidelines for treatment, but recommend the initial treatment with oral alkylating agents and steroids followed by radiotherapy for Ann Arbor stage II tumors and stage I of the palate lymphoma and the nasal cavity lymphoma extended to paranasal sinus.

  • 본 연구에 사용한 아라비녹실란화합물은 미강에서 추출한 헤미셀룰로즈에 표고버섯균사체 배양물에서 분리한 효소를 작용시켜 생성된 식물성다당류이며, PSP(polysaccharide peptide)는 담자균류의 일종인 Coliolus versicocor Sov-1의 균사체에서 추출 정제하여 얻은 단백다당체 성분이다. 이들에 대한 면역세포 활성화 효과, 항암 효과 및 알레르기 억제효과 등에 관한 실험 결과는 다음과 같다. 비장세포의 B cell과 T cell에 arabinoxylane과 PSP의 항체생성과 세포활성능을 조사한 결과 PFC형 성은 10 ∼ 15%, RFC검출은 10 ∼ 30% 증가하였다 복강침출세포로부터 대식세포의 탐식능 효과는 대조군에 비하여 PSP는 약 18%, arabinoxylane은 22% 정도 증가하였다. S-180 고형암에 의한 항암실험에서 arabinoxylane은 66.2%(p<0.01), PSP는 49.0%(p<0.05)의 억제 효과를 확인할 수 있었다. 복수암에 의한 수명 연장효과는 PSP, arabinoxylane이 대조군에 비해 다소의 수명연장효과가 나타났으며, PSP가 아라비녹실란에 비해 약간의 높은 수명연장효과가 나타났다. 항알레르기 효과를 보기 위한 PCA 역가를 측정한 결과는 대조군이 80인데 비해 PSP군은 40, arabinoxylane군은 20으로 대조군에 비하여 다소 경감되었으며, arabinoxylane군이 다소 우수한 결과를 보였다. 혈중 histamine 함량도 PCA와 유사한 결과로 arabinoxylane군과 PSP군이 히스타민 함량을 다소 감소시키는 경향을 보였다.

  • 연구배경 : 내피세포와 백혈구 및 상피세포에서 주로 발견되는 sICAM-1은 백혈구 표면의 배위자인 (ligand)인 LFA-1과 결합함으로서 염증성 질환 이외에 악성 종양의 전이와 진행에 중요한 역할을 하는 것으로 알려졌다. 최근에는 혈청내 sICAM-1의 농도가 악성 흑세포종의 전이와 비례하여 증가되는 것으로 보고되었으며, 또한 sICAM-1의 이형이 여러 질환에서 발견되고 이들의 혈청 농도의 증가는 위암, 대장암, 담낭암, 췌장암의 간전이와 관련되며, 악성 흑세포종 환자의 생존율의 감소와 관련되는 것으로 보고하였으나 폐암에서는 이에 대한 보고는 거의 없다. 이에 저자들은 폐암 환자의 혈청에서 sICAM-1을 측정하여 폐암의 조직학적 분류와 진행 및 전이의 정도에 따른 변화를 알아보고 폐암의 진단적 가치에 대하여 알아 보고자 하였다. 방법 : 1995년 1월부터 1996년 3월까지 전북대학교병원 내과에 입원하여 폐암을 진단 받은 환자 38명을 대상으로 하였으며, 정상 대조군은 비슷한 연령의 다른 질환을 갖고 있지 않은 8명을 대상으로 하였으며, 기관지 내시경을 통한 조직 생검이나 경피적 세침 흡입술을 이용하여 확진을 하였으며, 각 조직학적 분류에 따른 진행정도를 알기 위하여 TNM system 을 이용하여 분류하였고, 소세포 폐암은 limited stage와 extensive stage로 분류하였다. Genzyme사의 Predicts sICAM-1 ELISA kit를 이용하여 혈청 sICAM-1농도를 측정하였다. 결과 : 1. 소세포 폐암군에서 혈청 sICAM-1은 정상 대조군에 비해 유의한 증가가 없었으나, extensive stage군에서 limited stage군에 비해 유의한 증가를 보였다. 2. 편평상피암군에서 혈청 sICAM-1은 정상 대조군에 비해 유의한 증가를 보였으며, stage IIIa기 이하군에 비해 stage IIIb기 이상군에서 유의한 증가를 보였다. 3. 선폐암 환자군에서 혈청내 sICAM-1은 정상 대조군에 비해 유의한 증가를 보였다. 결론 : 혈청 sICAM-1농도의 변화는 폐암의 조직학적 분류에 따라 다르게 나타나며, 폐암의 전이 및 진행과 관련이 있을 것으로 보인다. 폐암 환자에서 혈청 sICAM-1농도의 측정은 폐암에서 진행의 정도를 평가하는 데 지표로서 이용될 수 있을 것으로 사료된다.

  • Background: To analyze the result of $^{18}F-FDG$ positron emission tomography (PET) in patients with a concomitant malignancy and tuberculoma in a tuberculosis (TB)-endemic area. Methods: Twelve patients with a concomitant malignancy and tuberculoma, who underwent whole-body $^{18}F-FDG$ PET, were evaluated retrospectively. The maximal standardized uptake values (SUVmax) of the malignancy and tuberculoma were compared. In 6 patients, $^{18}F-FDG$ PET was repeated during the anti-TB treatment and the changes in SUVmax were analyzed. Results: Of the 12 patients, 10 were male. The mean age was $67.2{\pm}7.9$ years. Tuberculomas were located in the lung (n=10) and lymph nodes (n=2), and tumors were located in the lung (n=6), colon (n=3), stomach (n=1), ovary (n=1) and liver (n=1). Although the mean SUVmax of malignant lesions was higher than that of tuberculomas ($5.2{\pm}3.2$ vs $3.5{\pm}2.0$), the difference was not significant. In 4 patients, the SUVmax was higher in the tuberculoma than the tumor. After anti-TB treatment in 6 patients, the mean SUVmax of the tuberculomas decreased significantly, from $3.5{\pm}2.0$ to $1.6{\pm}0.9$ (p=0.028). Conclusion: In patients with a concomitant malignancy and tuberculoma, SUVmax alone could not differentiate between them. However, $^{18}F-FDG$ PET may be useful in monitoring the response to anti-TB treatment.

  • This study investigated the possible effects and molecular mechanisms of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced hemorrhagic cystitis (HC) in rats. Inflammation response was assessed by histopathology and serum cytokines levels. We determined the protein expressions of nuclear transcription factor kappa-B (NF-${\kappa}B$), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), oxidative stress, urinary nitrite-nitrate, malondialdehyde (MDA), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Finally, we studied the involvement of mitogen-activated protein kinases (MAPKs) signaling in the protective effects of DADS against CP-induced HC. CP treatment caused a HC which was evidenced by an increase in histopathological changes, proinflammatory cytokines levels, urinary nitrite-nitrate level, and the protein expression of NF-${\kappa}B$, COX-2, iNOS, TNF-${\alpha}$, p-c-Jun N-terminal kinase (JNK), and p-extracellular signal regulated kinase (ERK). The significant decreases in glutathione content and glutathione-S-transferase and glutathione reductase activities, and the significant increase in MDA content and urinary MDA and 8-OHdG levels indicated that CP-induced bladder injury was mediated through oxidative DNA damage. In contrast, DADS pretreatment attenuated CP-induced HC, including histopathological lesion, serum cytokines levels, oxidative damage, and urinary oxidative DNA damage. DADS also caused significantly decreased the protein expressions of NF-${\kappa}B$, COX-2, iNOS, TNF-${\alpha}$, p-JNK, and p-ERK. These results indicate that DADS prevents CP-induced HC and that the protective effects of DADS may be due to its ability to regulate proinflammatory cytokines production by inhibition of NF-${\kappa}B$ and MAPKs expressions, and its potent anti-oxidative capability through reduction of oxidative DNA damage in the bladder.

  • Objective : Oriental medicines have been combined oriental medical theory which based on the seven modes of emotions. Notopterygium incisum (N. incisum) and Clematis manshurica (C. manshurica) have been used as an anti-rheumatic and analgesic medicine for the treatment of rheumatism, headache, cold, etc. In this study, we evaluate the synergistic anti-inflammatory effect of N. incisum and C. manshurica. Method : To evaluate the synergistic anti-inflammatory effect of a herbal mixture N. incisum and C. manshurica, we examined the changed ear thickness in 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced mouse ear edema model after topical application of herbal mixture. In addition, the levels of markers for inflammation, such as tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, prostaglandin $G_2$ ($PGE_2$), and nitric oxide (NO) were measured by ELISA assay and Griess reagent in lipopolysaccharide-stimulated Raw 264.7 cells. Results : Our results showed that aqueous extracts of N. incisum and C. manshurica combination significantly inhibited the mouse ear edema induced by TPA. Moreover, the aqueous extracts of N. incisum and C. manshurica combination exhibited synergistic effects in down-regulating TNF-${\alpha}$, IL-$1{\beta}$, $PGE_2$ level, but not NO. Conclusions : This study suggested that combined treatment of N. incisum and C. manshurica, based on seven methods in prescription compatibility, has a synergistic effect in down-regulating inflammatory response both in vitro and in vivo models.

  • We examined that the protective effects of ANX1 on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced skin inflammation in animal models using a Tat-ANX1 protein. Topical application of the Tat-ANX1 protein markedly inhibited TPA-induced ear edema and expression levels of cyclooxygenase-2 (COX-2) as well as pro-inflammatory cytokines such as interleukin-1 beta (IL-$1{\beta}$), IL-6, and tumor necrosis factor-alpha (TNF-${\alpha}$). Also, application of Tat-ANX1 protein significantly inhibited nuclear translocation of nuclear factor-kappa B (NF-${\kappa}B$) and phosphorylation of p38 and extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) in TPA-treated mice ears. The results indicate that Tat-ANX1 protein inhibits the inflammatory response by blocking NF-${\kappa}B$ and MAPK activation in TPA-induced mice ears. Therefore, the Tat-ANX1 protein may be useful as a therapeutic agent against inflammatory skin diseases.

  • 본 연구에서는 미야베 에탄올 추출물의 항염증 활성을 확인하기 위해 LPS로 활성화된 RAW 264.7 세포와 croton-oil로 유도된 귀부종 동물 모델을 이용하였다. 그 결과, SMYEE 50 및 $100{\mu}g/ml$ 농도처리 시, LPS로 유도된 염증반응에서 $NF-{\kappa}B$ 활성 억제와 더불어 MAPKs의 인산화를 효과적으로 억제함을 보였다. LPS에 의해 증가된 NO와 전염증성 사이토카인의 분비량도 농도 의존적으로 감소하였다. 또한 SMYEE는 croton oil로 부종을 유발한 마우스모델에서 귀부종 억제효과를 나타내었고, 조직의 진피 두께 및 mast cell의 수가 현저히 감소하였음을 확인하였다. 이를 통해 SMYEE는 염증 반응의 전사인자인 $NF-{\kappa}B$ 및 MAPKs의 활성을 조절함으로써 iNOS와 COX-2의 발현 및 전염증성 매개인자인 NO, IL-6, $TNF-{\alpha}$$IL-1{\beta}$의 분비를 억제하여 항염증 활성을 가지는 것을 확인하였다. 현재까지 미야베 모자반내의 항염증 효능 물질에 관한 연구는 보고되지 않고 있으며 향후 실험을 통해 미야베 모자반 에탄올 추출물로부터 항염증 효과를 가지는 유효성분을 밝히기 위한 분리 연구를 진행할 예정이다.
