Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a rare subtype of primary cutaneous lymphoma with a favorable prognosis. Primary cutaneous CD30+ lymphoproliferative disorders, which include C-ALCL and lymphomatoid papulosis, are the second most common group of cutaneous T-cell lymphomas. C-ALCL is comprised of large cells with anaplastic, pleomorphic, or immunoblastic cytomorphology, and indeed, more than 75% of the tumor cells express the CD30 antigen. C-ALCL clinically presents with solitary or localized reddish-brown nodules or tumors, and sometimes indurated papules, and they may be with ulceration covering with dark eschar. Multifocal lesions are seen in 20% of the patients. Extracutaneous dissemination, which mainly involves the regional lymph nodes, occurs in 10% of patients. A 69-year-old man noticed a mild elevated cutaneous lesion containing central ulceration covering with brownish black necrotic tissue on the right lower lip, and the lesion was surgically removed. After the first operation, another skin lesion was developed and the histological examination confirmed the diagnosis, C-ALCL. Eight specimens were excised during the 7-month follow-up period. The patient started the treatment with low-dose oral methotrexate (15 mg/wk) and there was no recurrence for 11 months.

Currently, a 70-year-old woman started suffering from S.I joint pain from 1973 and had severe pain in the S.I joint, wrist, and elbow from 1975 to 1977, and was diagnosed with spinal tuberculosis at a general hospital. From 1978 to 1987, she suffered from chronic fatigue and insomnia, and since January 1, 1988, she was unable to get up while lying down, suffering from whole body joint, muscle pain, and fibromyalgia. In May 1989, she was also diagnosed with ankylosing spondylitis through genetic testing at the Catholic St. Mary's Hospital Rheumatology Department in Korea, and was treated with sulfasalazine, analgesic, and immunosuppressant, methotrexate, for 12 years until 1999, but none of the drugs eliminated the pain. She was hospitalized and discharged repeatedly, and continued to receive salt water poultice and exercise therapy at home, but was unable to move at all. In 2000, after biologic treatment with Remicade injection (Remsima®), she was able to walk and move, and after that, she was continuously prescribed biologics. From 2015 to 2019, Enbrel® (Etanercept) injection was prescribed once a week, but the symptoms such as severe pain (joint and muscle, fibromyalgia), scleroderma, Sjogren's syndrome (dryness of eyes, nose and mouth), difficulty swallowing, chronic fatigue, and stiff body appeared. Around January 2018, hepatic indicators were high and lymphocytes became enlarged. However, most serious injuries were highly improved after the OCNT combination therapy using active phytonutrients, anthocyanin-fucoidan nanocomplex. Therefore, for patients with such experiences, OCNT treatment is proposed as an alternative.

Background: Commensal bacteria play an important role in the pathogenesis of inflammatory bowel disease (IBD) and probiotics have been used as treatment options. We aimed to explore the current use of probiotics and factors associated with their prescription in patients with IBD. Methods: This cross-sectional study was conducted on a single hospital-based cohort. Patients were eligible if they were ≥18 years old, visited the IBD clinic as an outpatient more than twice during the study period, and had a confirmed diagnosis of IBD. Patients were divided into two groups based on the prescription of probiotics. Clinical assessments were compared between the two groups. Results: In total, 217 patients were enrolled in this study. In patients with Crohn disease (CD), moderate or severe abdominal pain; prior use of methotrexate (MTX), iron, thiopurines, or biologics; history of IBD-related surgery; and stool frequency were independently associated with the prescription of probiotics. In patients with ulcerative colitis (UC), moderate or severe abdominal pain, hematochezia, stool frequency, and moderate or severe physician global assessment score were independently associated with the prescription of probiotics. Conclusion: Increased disease activity may be associated with fewer prescriptions of probiotics in patients with IBD. However, physicians prescribed probiotics to control symptoms, such as abdominal pain and increased stool frequency in patients with UC and CD, and hematochezia in patients with UC. Additionally, the use of MTX and iron, and a history of IBD-related surgeries were associated with more frequent probiotic prescriptions in patients with CD.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is defined as the occurrence of tubulointerstitial nephritis and uveitis in the absence of other systemic diseases. Three pediatric cases have been reported in the Republic of Korea, and we now report a fourth case. A 15-year-old girl presented to the ophthalmology department with a 1-week history of bilateral ocular discomfort that worsened on the day of presentation with redness and pain in both eyes. She was diagnosed with bilateral uveitis, and her baseline examination revealed moderate renal dysfunction and mild proteinuria. A renal biopsy was performed and confirmed the diagnosis of TINU syndrome. She was started on steroid eye drops and a 12-week course of oral steroids at a dose of 40 mg/m²/day, which completely resolved the proteinuria and mild renal function to an estimated glomerular filtration rate of 60 mL/min/1.73 m². However, the uveitis did not improve, and despite the addition of oral methotrexate as a second-line treatment, the uveitis remains unresponsive to treatment over 21 months. Further evaluation and treatment are ongoing, and active therapeutic intervention is suggested even at a pediatric age, considering the lack of improvement in renal function and uveitis to date.

Adalimumab is a full human monoclonal antibody that inhibits tumor necrosis factor-alpha (TNF-${\alpha}$). This has recently been shown to be effective in the treatment of rheumatoid arthritis (RA), ankylosing spondylitis, and other conditions. Sacoidosis is known to be the target for adalimumab but we describe a patient who has developed sarcoidosis with lung involvement during adalimumab therapy for RA. A 48-year-old woman, who was treated with adalimumab for 5 months, was admitted because of chronic cough and both hilar lymphadenopathy on chest radiography. Chest computed tomography revealed the enlargement of multiple lymph nodes in the right supraclavicular, subcarinal, both hilar and right axillary area. She was diagnosed with sarcoidosis based on the biopsy of supraclavicular lymph node, skin and lung through video-associated thoracoscopic surgery, which was non-caseating epitheloid cell granuloma and excluded from a similar disease. She was treated for sarcoidosis with prednisolone and methotrexate instead of adalimumab.

Human chorionic gonadotropin (hCG) is a heterodimeric glycoprotein hormone consisting of non-covalently linked two subunits, the ${\alpha}$ and ${\beta}$ subunit. It has been used as a infertility drug for ovulation to mimic luteinizing hormone $(LH).^{1)}$ A stable cell line was established by transfection of Rc/CMV-i-dhfr-hCG, expression vector containing hCG ${\alpha}-$ and ${\beta}-genes$, into dihydrofolate reductase-deficient CHO cells and subesquent methotrexate-mediated gene amplification. Anchorage-dependent CHO cells were adapted into a serum-free and/or animal component-free suspension medium through gradual serum weaning for the hCG production. The established cell line showed typical morphological characteristics and growth profile of CHO cells, and could produce FSH with passage-to-passage consistency. The high density perfusion culture of the CHO cells was carried out in Celligen Plus bioreactor equipped with a spin-filter as a internal cell retention device. The cell density reached up to $>1x10^{7}$ cells/ml in less than 7 days and a perfusion-control strategy based on cellular consumption rates of glucose was $established.^{2)}$ Biologically active recombinant hCG was purified by a series of chromatographic steps including anion exchange chromatography and hydrophobic interaction chromatography to homogeneity. The highly purified recombinant hCG was characterized for physicochemical, immunological and biological properties.

Recently, the incidence of pulmonary cryptococcosis is gradually increasing in rheumatoid arthritis (RA) patients. Pulmonary rheumatoid nodules (PRN) are rare manifestations of RA. Eighteen months ago, a 65-year old woman was admitted to hospital due to multiple nodules ( $2.5{\times}2.1{\times}2cm$) with cavitations in the right lower lobe. She was diagnosed with RA three year ago. She had been taking methotrexate, leflunomide, and triamcinolone. A video-assisted thoracoscopic surgery biopsy was performed and PRN was diagnosed. However, a newly growing huge opacity with cavitation was detected in the same site. Pulmonary cryptococcal infection was diagnosed through a transthoracic computed tomograpy guided needle biopsy. Cryptococcus antigen was detected in serum but not in cerebrospinal fluid. The patient was treated with oral fluconazole which resulted clinical improvement and regression of the nodule on a series of radiography. Herein, we report the case of pulmonary cryptococcosis occurring in the same location as that of the PRN.

The present study was carried out to investigate the effects of nanopowdered peanut sprout-added Caciocavallo cheese (NPCC) on the prevention and treatment of rheumatoid arthritis in DBA/IJ mice immunized with type II collagen. After the induction of arthritis, the mice were being divided into five groups: (1) normal, no immunization; (2) CIA, collagen-induced arthritis; (3) MTX, collagen-induced arthritis treated with methotrexate (0.3 mg/kg body weight); (4) CC, collagen-induced arthritis treated with Caciocavallo cheese (0.6 g/d); (5) NPCC, collagen-induced arthritis treated with nanopowdered peanut sprout-added Caciocavallo cheese (0.6 g/d). Nanopowdered peanut sprout was ranged from 300 to 350 nm, while regular powdered peanut sprouts were ranged from 50 to $150{\mu}m$. The NPCC group had considerable reductions of clinical scores and paw thicknesses at the end of experiment as compared to the CIA group. In the serum analysis, the TNF-${\alpha}$, IL-$1{\beta}$, IL-6 and $IgG_1$ levels in the NPCC group have decreased by 69.4, 75.9, 66.6, and 61.9%, respectively, when compared to the CIA group. The histological score and spleen index of the NPCC group were significantly lower than the CIA group. In conclusion, the feeding NPCC method could delay and/or prevent the rheumatoid arthritis in the collagen-induced arthritis mouse model. Based on this study, nanopowdered peanut sprouts could be applied to various functional cheeses.

Rheumatoid arthritis (RA) is a systemic autoimmune disease with chronic inflammation characterized by hyperplasia of synovial cells in affected joints, which might be mediated by the altered activation of Immune system, ultimately leading to the destruction of cartilage and bone. To examine effects of GHS on rheumatoid arthritis DBA/1J mice were immunized with bovine type II collagen to induced arthritis and then treated with GHS once a day for 7 weeks. Oral administration of GHS (200 mg/Kg) significantly suppressed the progression of CIA, which extend is comparable to that of methotrexate (MTX, 0.3 mg/Kg), a positive control. The severity of arthritis within the knee joints, which was evaluated by histological assessment of cartilage destruction and pannus formation, was also lowered by GHS. The production of TNF-and IL-6 in serum was significantly suppressed. The levels of IFN-g in the culture supernatant of splenocytes stimulated with CD3/CD28 or collagen were dramatically decreased, while those of IL-4 was increased. The levels of IgG and IgM RA factor were also decreased in the serum. FACS analysis indicated that B cells (in DLN), CD3+ T cells (in spleen, and paw joint), CD11b+Gr-1+ cells (in paw joint), CD3+CD49b(DX5) (in PBMC) were decreased and there was increased proportion of CD3+, CD4+, CD8+, CD4+CD25+ T cells in DLN. In conclusion, our results demonstrates that GHS significantly suppressed the progression of CIA and this action was characterized by the decreased production of TNF-a, IL-6, and rheumatoid factors, and modulations of immune cell populations.

Metabolic inhibitors which act in the process of pyrimidine salvage influenced on the uracil incorporation into nucleic acids of Toxoplasma. Inhibitors of dihydrofolate reductase, pyrimethamine and methotrexate, and inhibitors of thymidylate synthase, fluoro-uridine, fluoro·dUMP and fluoro-uracil, diminished isotopic uracil uptake in dose-dependent manners. Azauridine which suppresses do novo pyrimidine biosynthesis did not affect the salvage even in a relatively high dose. These results suggested that the activation of uracil salvage should be closely related with the function of TMP biosynthetic enzymes. The pattern of thymidine uptake had no differences between control HL-60 cells and Toxoplasma infected cells, which did not reject the specific proliferation of Texoplasma. It can be exploited to characterize the elects of various compounds related with the proliferation of Toxoplasma, especially its DNA synthesis. Key words: Toxoplasma gondii, uracil salvage, dihydrofolate reductase, thymidylate synthase TMP biosynthesis.
