Focal segmental glomerulosclerosis(FSGS) has been detected in approximately 10% of cases of Idiopathic nephrotic syndrome in children, and exhibits a poor response to initial steroid therapy, as well as a higher rate of progression to chronic renal failure and relapse after kidney transplantation. We describe a case of an eleven year-old boy with steroid-resistant FSGS who exhibited a response to a second trial of cyclosporin h(CsA) therapy. At the age of 26 months, this patient was diagnosed with steroid-resistant FSGS. For 9 years, he had undergone a gauntlet of therapies to induce remission; oral steroids, cyclophosphamide, methylprednisolone(mehyIPd) pulse therapy, CsA, and ibuprofen therapy. Although these therapies failed to induce remission, the patient's renal function remained In the normal range during the nine years of treatment. At the age of ten years, the patient's proteinuria decreased, and complete remission was attained with a second administration of CsA, coupled with a low dose of oral steroids. This patient continues to receive CsA without relapse. Therefore, our major concern involves the possibility of relapse after the discontinuation of CsA therapy Our findings in this case suggest that, in cases of refractory FSGS, if renal insufficiency does not emerge, aggressive therapy for the amelioration of proteinuria should be continuously pursued.

Idiopathic nonspecific interstitial pneumonia (NSIP) is one of the varieties of idiopathic interstitial pneumonias. Diagnosis of idiopathic NSIP can be done via multidisciplinary approach in which the clinical, radiologic, and pathologic findings were discussed together and exclude other causes. Clinical manifestations include subacute or chronic dyspnea and cough that last an average of 6 months, most of which occur in non-smoking, middle-aged women. The common findings in thoracic high-resolution computed tomography in NSIP are bilateral reticular opacities, traction bronchiectasis, reduced volume of the lobes, and ground-glass opacity in the lower lungs. These lesions can involve diffuse bilateral lungs or subpleural area. Unlike usual interstitial pneumonia, honeycombing is sparse or absent. Pathology shows diffuse interstitial inflammation and fibrosis which are temporally homogeneous, namely NSIP pattern. Idiopathic NSIP is usually treated with steroid only or combination with immunosuppressive agents such as azathioprine, cyclophosphamide, cyclosporine, and mycophenolate mofetil. Prognosis of idiopathic NSIP is better than idiopathic pulmonary fibrosis. Many studies have reported a 5-year survival rate of more than 70%.

Many probiotic species have been used as a fermentation starter for manufacturing functional food materials. We have isolated Bifidobacterium animalis subsp. lactis LDTM 8102 from the feces of infants as a novel strain for fermentation. While Glycine max has been known to display various bioactivities including anti-oxidant, anti-skin aging, and anti-cancer effects, the immune-modulatory effect of Glycine max has not been reported. In the current study, we have discovered that the extract of Glycine max fermented with B. animalis subsp. lactis LDTM 8102 (GFB 8102), could exert immuno-modulatory properties. GFB 8102 treatment increased the production of immune-stimulatory cytokines in RAW264.7 macrophages without any noticeable cytotoxicity. Analysis of the molecular mechanism revealed that GFB 8102 could upregulate MAPK2K and MAPK signaling pathways including ERK, p38, and JNK. GFB 8102 also increased the proliferation rate of splenocytes isolated from mice. In an animal study, administration of GFB 8102 partially recovered cyclophosphamide-mediated reduction in thymus and spleen weight. Moreover, splenocytes from the GFB 8102-treated group exhibited increased TNF-α, IL-6, and IL-1β production. Based on these findings, GFB 8102 could be a promising functional food material for enhancing immune function.

Probiotics are currently considered as one of tools to modulate immune responses under specific clinical conditions. The purpose of this study was to evaluate whether oral administration of three different probiotics (Lactiplantibacillus plantarum CJLP243, CJW55-10, and CJLP475) could evoke a cell-mediated immunity in immunodeficient mice. Before conducting in vivo experiments, we examined the in vitro potency of these probiotics for macrophage activation. After co-culture with these probiotics, bone marrow derived macrophages (BMDMs) produced significant amounts of proinflammatory cytokines including interleukin-6 (IL-6), IL-12, and tumor necrosis factor-α (TNF-α). Levels of inducible nitric oxide synthase (inos) and co-stimulatory molecules (CD80 and CD86) were also upregulated in BMDMs after treatment with some of these probiotics. To establish an immunocompromised animal model, we intraperitoneally injected mice with cyclophosphamide on day 0 and again on day 2. Starting day 3, we orally administered probiotics every day for the last 15 d. After sacrificing experimental mice on day 18, splenocytes were isolated and co-cultured with these probiotics for 3 d to measure levels of several cytokines and immune cell proliferation. Results clearly indicated that the consumption of all three probiotic strains promoted secretion of interferon-γ (IFN-γ), IL-1β, IL-6, IL-12, and TNF-α. NK cell cytotoxicity and proliferation of immune cells were also increased. Taken together, our data strongly suggest that consumption of some probiotics might induce cell-mediated immune responses in immunocompromised mice.

This study aims to explore the impact of Rehmannioside D (RD) on ovarian functions of rats with diminished ovarian reserve (DOR) and its underlying mechanisms of action. A single injection of cyclophosphamide was performed to establish a DOR rat model, and fourteen days after the injection, the rats were intragastrically administrated with RD for two weeks. Rat estrus cycles were tested using vaginal smears. Ovarian tissues were histologically evaluated, the number of primordial, mature, and atretic follicles was calculated, and the apoptotic rate of granulosa cells. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E₂) levels were determined by ELISA assays. Protein levels of Forkhead Box O1 (FOXO1), KLOTHO, Bcl-2, and Bax were investigated in ovarian tissues of DOR rats. The binding between FOXO1 and KLOTHO was verified by ChIP assay. High-dose administration of RD into DOR rats improved their estrus cycles, increased ovarian index, enhanced the number of primordial and mature follicles, reduced the number of atretic follicle number, and ovarian granulosa cell apoptosis in addition to inhibiting FSH and LH levels and upregulating E₂ expression. FOXO1 and KLOTHO were significantly suppressed in DOR rats. FOXO1 knockdown partially suppressed the protective effects of RD on DOR rats, and KLOTHO overexpression could restore RD-induced blockade of DOR development despite knocking down FOXO1. FOXO1 antibody enriched KLOTHO promoter, and the binding between them was reduced in DOR group compared to that in sham group. RD improved ovarian functions in DOR rats and diminished granulosa cell apoptosis via the FOXO1/KLOTHO axis.

목 적 : 방사선조사는 망막모세포종의 국소적 치료에 효과적인 방법이나 장기 생존자에서 안면발육장애, 각막과 시신경 손상, 이차적인 암의 발생 등의 합병증을 유발하며 방사선조사로 인한 안면발육부전은 나이가 들수록 더욱 심각한 미용적 장애를 초래하고 환자의 삶의 질을 저하시킨다. 진행된 안구 내 망막모세포종과 안와 내 망막모세포종 환자에서 안구적출술과 항암화학치료 및 안와방사선조사를 받은 경우와 받지 않은 경우의 치료성적과 장기예후를 분석하고자 본 연구를 시도하였다. 방 법 : 1985년 10월부터 2006년 12월까지 영남대학교병원에서 망막모세포종으로 진단받은 35명의 환자를 대상으로 병록지를 후향적으로 분석하였다. 안구 내 병변은 Reese-Ellsworth(RE)의 분류에 따라, 안구 외로 진행된 경우는 Grabowski-Abramson (GA)의 분류에 따라 분류하여 RE group III, IV, V인 진행된 안구 내 종양과 GA stage II인 안와 내 종양 환자를 연구 대상으로 하였다. 결 과 : 연구에 포함된 환자는 18명이었고, 진단당시 나이의 중앙값은 27개월(범위 2-69개월), 추적기간의 중앙값은 73.5개월(범위 6-219개월)이었다. 안구 내에 국한된 경우는 6명이었고(RE group III; 2명, IV; 1명, V; 3명) 안와 내로 진행된 경우는 12명이었다(GA stage II). 대상 환아 모두에서 안구적출술을 시행한 후 항암화학치료를 시행하였는데 2001년 이전에는 vincristine, adriamycin, cyclophosphamide, cisplatin, VM-26을, 2001년 이후로는 vincristine, etoposide, carboplatin을 사용하였다. 9명의 환자에서는 국소적으로 방사선조사를 병행하였고, 총 방사선 조사량의 중앙값은 4,500 cGy(범위 3,500-5,000 cGy)이었다. 방사선조사를 병행하여 치료 받은 환아 9명 중 7명은 재발이나 전이 없이 장기생존하였으며, 장기 생존자 모두에서 심한 안면 골격의 비대칭적 발육부전이 나타났다. 방사선조사 없이 치료받은 9명 중에서는 재발이나 전이가 한명도 없이 모두 장기생존하였으며, 안구적출술 이후 인공안와삽입물을 삽입하였으며 안면 골격 발달은 모두 대칭적으로 정상 발육을 하였다. 결 론 : 시신경의 절제면을 침범하지 않은 안와내에 국한된 망막모세포종의 치료에 있어 방사선조사를 제외하고 안구적출술, 항암화학치료, 국소적 치료를 병행함으로써 높은 생존율을 유지하면서 안면발육부전과 같은 심각한 부작용을 줄여 삶의 질을 향상시킬 수 있을 것으로 생각된다. 그러나 시신경의 절제면을 침범한 경우에는 재발의 가능성이 있으므로 후기 후유증의 위험이 있더라도 안구적출술 후 방사선조사와 항암화학치료를 병행한 치료를 시행함으로써 생존률을 높일 수 있을 것으로 생각된다.

연구 배경: 고위험군의 악성 질환의 치료로 최근에 시도되고 있는 고용량 항암화학요법은 기존의 치료보다 치료 반응율이 높고 생존의 향상을 기대할수 있는 방법이다. 그러나 치료와 관련된 부작용도 있어 이환율 및 사망률도 높다. 말초 조혈모세포이식을 이용한 고용량 항암화학요법 후에 발생하는 특발성 폐렴 증후군은 감염성 원인을 배제한다면 약제에 의한 폐독성으로 유발되었을 가능성이 가장 높다. 저자들은 약제 독성으로 유발되었을 것으로 추정되는 폐렴 증후군에 대하여 알아보고자 하였다. 방법: 1995년 5월부터 1997년 12월까지 아주대학교병원에서 말초 조혈모세포이식을 이용한 고용량 항암화학 요법을 시행받은 환자들을 대상으로 하였다. 이들 중 특발성 폐렴 증후군이 발생한 5례에서 경기관지폐생검을 시행하고 그 임상 양상과 치료 결과를 후향적으로 분석하였다. 결과: 전체 대상 환자는 97례이었으며 이들중 5례(5.1%)에서 특발성 폐렴 증후군이 발생하였다. 5례의 환자의 연령은 평균 $41{\pm}13$세, 남녀비는 3:2였으며 유방암 3례, 악성 림프종 2례이었다. 사용된 항암제는 CBP regimen 3례, BEAC regimen 1례, BEAM regimen 1례이었으며, 사용된 용량은 BCNU 300-400 mg/$m^2$, cyclophosphsmide 6,000 mg/$m^2$이었다. 다섯 례 모두에서 고용량 항암화학요법 전에 방사선 치료를 받았다. 고용량 항암화학요법을 시행한지 평균 14주 후 (4-26주)에 기침, 호흡곤란, 발열 등을 동반한 폐침윤이 발생하였다. 흉부 방사선 검사 소견상 3례에서는 양측성, 2례에서는 우하엽에 국한된 미만성의 폐침윤을 보였다. 경기관지폐생검 결과 폐포 손상과 격막의 비후, 비정상적인 제 II 형 폐세포의 증식이 관찰되었고 악성 세포의 침윤이나 감염성 질환 등의 소견은 없었다. 모든 환자에서 스테로이드를 투여하였으나 2례에서는 급성 호흡부전증으로 진행하여 사망하였다. 3례에서는 폐병변이 소실되고 중상도 호전되었으나 1례는 확장성 심근병으로 사망하였고 2례는 호전되어 폐병변이 없는 상태에서 외래 관찰 중이다. 결론: 말초 조혈모세포이식을 이용한 고용량 항암화학요법은 치료 효과가 기존의 항암치료보다 높지만 BCNU를 포함하는 복합 화학요법을 사용하는 경우 약제에 폐손상이 발생할 가능성이 있어 적절한 환자의 선정과 폐손상을 최소화할 수 있도록 유의하여야 한다.

The KGBT has been used to weak children with anorexia, fatigue, and growth retardation. This study was carried out to prove the effects of the hematopoiesis and the immune proliferation by KGBT. Previously, C57BL/6 mice was treated with cyclophosphamide(100mg/kg) for leukopenia, and then administered KGBT (concentration is 1.37 g/kg, 504 mg/kg, and 137 mg/kg) to the treated mice. The mice was analyzed expression of thrombopoietin(TPO), stem cell factor(SCF) and interleukin-3 from bone marrow cell, interleukin-10 (IL-10), and interferon-$ {\gamma}$(INF-${\gamma}$) from splenic cell, and NOSⅡ gene from macrophage using by RT-PCR. Also proliferation of immune cell was analyzed using 3H-thymidine uptake and flow cytometery in splenic cells. The results were obtained as follows ; 1. The total number of WBC, RBC and PLT was increased in the KGBT treated group than in the control group. 2. In vitro, the proliferation of splenic cells was increased in normal, control, and KGBT treated group. And Administration of KGBT was reduced the cytotoxicity by CTX. 3. In bone marrow cell, the gene expression of immune regulatory factor that associated with hematopoiesis, such as TPO, SCF, and IL-13 was increased in the KGBT treated group than control. 4 The titer of hemagglutinin and hemolysin was increased in the KGBT treated group than control. 5. In analysis of positive leucocytes from splenic cell of BALB/c mice, the subpopulation percent of CD4+, CD8+,and CD19+ was increased in the KGBT treated group than control.
