Advanced Hodgkin's disease is usually treated with six or more cycles of combination chemotherapy. Spontaneous regression of the cancer is very rarely reported in patients with Hodgkin's disease. We present an unusual case of a patient with Hodgkin's disease who experienced complete remission with a single cycle of chemotherapy, followed by pneumonia. The case was a 36-year-old man diagnosed with stage IVB mixed cellularity Hodgkin's disease in November 2000. After treatment with one cycle of COPP-ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine) chemotherapy without bleomycin, the patient developed interstitial pneumonia and was cared in the intensive care unit (ICU) for two months. Follow-up chest computerized tomography (CT), performed during the course of ICU care, revealed markedly improved mediastinal lymphomatous lesions. Furthermore, follow-up whole body CT and 18-fluorodeoxyglucose positron emission tomography showed complete disappearance of the lymphomatous lesions. Four years later, the patient is well and without relapse. This report is followed by a short review of the literature on spontaneous regression of Hodgkin's disease. To the best of our knowledge, this is the first case report of spontaneous remission of Hodgkin's disease in Korea.

OBJECTIVETo investigate effective doses of cyclophosphamide (CTX) for establishment of leukopenia model in ICR mouse.
METHODSNormal ICR mice (n = 96) were divided into CTX(80), CTX(100), CTX(120), CTX(150) and CTX(300) groups, of which mice received CTX intraperitoneally at a dose of 80, 100, 120, or 150 mg/kg once a day for 3 consecutive days, or 300 mg/kg with single injection. The peripheral blood cell counts were detected at various times before and after CTX administration.
RESULTSThe peripheral white blood cell nadirs in the mice injected with CTX appeared on day 4 after the first dose of CTX. The peripheral white blood cell nadir in group CTX(100) was 26.7% of the value measured in mice before CTX administrated, and that of group CTX(80) was 35.0%. Higher doses of CTX, however, caused too severity in hematopoietic injury.
CONCLUSIONThe dose of CTX 100 mg/(kg·d) × 3d is appropriate for leucopenia model of ICR mouse.

4.Establishment of an animal model of azoospermia in male mice.
National Journal of Andrology 2007;13(2):147-149
OBJECTIVETo establish a stable animal model of azoospermia in male mice.
METHODSTwo groups of mice, with 30 in each, were intervened respectively by chemotherapy (intraperitoneal injection of Busulfan and Cyclophosphamide) and subcutaneous injection of Estradiol. At different times after the injection, the microscopic structures of the seminiferous tubules of both groups were observed and compared. The recovery of the germ cells in the seminiferous tubules was also evaluated after the termination of the intervention.
RESULTSA stable animal model was established by chemotherapeutic method with Busulfan and cyclophosphamide, while the model constructed by muscle injection of Estradiol was not stable.
CONCLUSIONCompared with estrogen injection, chemotherapeutic intervention is a reliable method for constructing an animal model of azoospermia in male mice.

OBJECTIVETo evaluate the efficacy and safety of the oral combination chemotherapy of furtulon (FTL) and cyclophosphamide (CTX) for advanced breast cancer (ABC).
METHODSFrom Jun 2000 to Jun 2002, eighty-three patients with ABC were treated with the two oral drugs as combined chemotherapy. The mean number of cycles was 5, median number of cycles was 6 (range 2-6).
RESULTSThe overall response rate was 45.8%, The median time to progression was 6 months. The treatment was well tolerated, with related Grade 3 clinical adverse effect being only nausea and vomiting in 2 patients (2.4%) and mild hematologic toxicities.
CONCLUSIONOral combined chemotherapy of FTL and CTX, being convenient and safe, is effective for patients with advanced breast cancer.

OBJECTIVETo investigate the efficacy, adverse events and long-term survival of cyclophosphamide, vindesine, cytarabine, dexamethasone and bleomycin (COAD-B) regimen for relapsed and refractory non-Hodgkin lymphoma (NHL).
METHODSEighty six patients diagnosed with relapsed or refractory NHL were included in our study from January 2007 to January 2013. The chemotherapy regimen was COAD-B, the therapeutic efficacy was evaluated every 2 courses. Once the stable disease (SD) or progress of the disease (PD) achieved, the patients would switch to other second-line regimens.
RESULTSThe overall response rate (ORR) was 67.4%, median remission duration was 13 months (3-51 months); 1-,2- and 4-year overall survival (OS) rates were 75.4%, 56.8% and 40.0%, respectively; 1-, 2- and 4-year progression-free survival (PFS) rates were 50.3%, 39.4% and 27.5%, respectively. The main adverse reaction of patients was myelosuppression. The response to chemotherapy and long- term survival of the relapsed patients were significantly better than that of the refractory ones, and the difference had statistical significance.
CONCLUSIONCOAD-B could be the salvage regimen for relapsed and refractory NHL.

8.HER2 over-expression and response to different chemotherapy regimens in breast cancer.
Journal of Zhejiang University. Science. B 2008;9(1):5-9
PURPOSETo exam the relationship between HER2 over-expression and different adjuvant chemotherapies in breast cancer.
PATIENTS AND METHODSA total of 1625 primary breast cancer patients who received post-surgery adjuvant chemotherapy in Tianjin Cancer Hospital, China, from July 2002 to November 2005 were included in the study. Among them, 600 patients were given CMF (CTX+MTX+5-Fu) regimen, 600 given CEF (CTX+E-ADM+5-Fu) regimen, and 425 given anthracyclines plus taxanes regimen, with mean follow-up time of 42 months.
RESULTSIn CMF treatment group, the 3-year disease free survival (DFS) in HER2 over-expressed patients was lower than that of the HER2-negative ones (89.80% vs 91.24%, P=0.0348); in node-positive subgroup, the 3-year DFS was 84.72% in HER2 over-expressed patients, and 90.18% in the HER-2-negative ones (P=0.0271). Compared to CMF regimen, anthracyclines and anthracyclines plus taxanes regimens are more effective (P<0.05) in node-positive HER2 over-expression than those in the node-negative.
CONCLUSIONHER2 over-expression is an independent index for predicting poor prognosis and short DFS for breast cancer patients. HER2 over-expressed patients are resistant to CMF regimen chemotherapy, but sensitive to anthracyclines-based or anthracyclines plus taxanes regimen. HER2 expression can be taken as a marker for therapies in breast cancer.

10.Oral Tolerance in Active Fatal Anaphylaxis.
Korean Journal of Immunology 1999;21(4):319-325
We have investigated whether oral administration of ovalbumin (OVA) could prevent active systemic anaphylaxis to the antigen. Oral tolerance was induced by a single feecfing with 40 mg OVA before, but not after, sensitization characterized by diminished OVA-specific IgE and IgG responses. Feeding 15 mg OVA suppressed anaphylaxis and antibody responses to a lesser extent. Spleen cells from tolerant donors were incapable of transferring the tolerance to naive recipients. Pretreatment of cyclophosphamide (100 mg/kg) 2 days before OVA feeding did not restore the tolerance. Furthermore, in vitro cell mixing studies showed that the proliferation of spleen cells from OVA- sensitized donors was not inhibited by the addition of spleen cells from tolerant donors, arguing against the role of suppressor cells. Anergy was demonstrated by the ability to reverse the tolerant state after culturing tolerant cells in the presence of IL-2. These findings indicate that only a high-dose (40 mg) feeding OVA was found to be effective in inducing tolerance in this experimental system, and demonstrate anergy as the mechanism underlying oral tolerance to systemic anaphylaxis.
