Purpose: This study aimed to evaluate weight changes in women during the period of TAC (docetaxel-doxorubicin-cyclophosphamide) chemotherapy after breast surgery and the differences in weight changes by disease characteristics among Korean women with breast cancer. Methods: The design of this study was retrospective survey research. The subjects of this study were 130 patients with fully completed TAC chemotherapy between January 2012 and April 2015. Body weight before their operation, and at 3 weeks, 6 weeks, 9 weeks, 12 weeks, 15 weeks, and 18 weeks after surgery, as well as general and disease characteristics, were reviewed via their medical charts. Results: The mean age of the patients was 51.2 years. The preoperative (baseline) mean weight was $59.4{\pm}8.44$. Significant weight losses were observed in the initial (1st 3 week) period of TAC chemotherapy compared to the baseline and significant weight losses were observed with the exception of the period 6 weeks after breast surgery. There were significant differences in mean weight changes according to the stage of breast cancer, radiotherapy, and hormone therapy among disease characteristics. Conclusion: It is necessary to study weight changes after breast surgery for the long periods of TAC chemotherapy. Through the accumulated results of studies, nursing programs for breast cancer patients must be developed for the prevention of weight gain in the periods of TAC chemotherapy.

Paeonol is a major phenolic micromolecular component of Moutan cortex Radicis, a traditional Chinese Medicine. It has shown antitumor effects in previous studies; however, the underlying mechanisms remain unknown. This study investigated the mechanism by giving treatments of placebo, cyclophosphamide, paeonol of 150 and 300 mg/kg to 4 groups of mice bearing EMT6 breast cancer. Apoptosis in tumor cells were confirmed by morphology analysis, including hematoxylin, eosin staining and TUNEL staining. The results showed that the weight of EMT6 breast tumor was significantly reduced in the groups treated with both 150 and 300 mg/kg of paeonol. Immunohistochemical and Western blot results showed that the expression of Bcl-2 was down-regulated while the expression of Bax, caspase 8 and caspase 3 was up-regulated respectively. These results suggest that paeonol exhibits antitumor effects and the mechanism of the inhibition is via induction of apoptosis, regulation of Bcl-2 and Bax expression, and activation of caspase 8 and caspase 3.

Background: Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects for patients undergoing chemotherapy. This study evaluated the protective effect of Korean Red Ginseng (KRG) on CIA in a well-established in vitro human hair follicle organ culture model as it occurs in vivo. Methods: We examined whether KRG can prevent premature hair follicle dystrophy in a human hair follicle organ culture model during treatment with a key cyclophosphamide metabolite, 4-hydroperoxycyclophosphamide (4-HC). Results: 4-HC inhibited human hair growth, induced premature catagen development, and inhibited proliferation and stimulated apoptosis of hair matrix keratinocytes. In addition, 4-HC increased p53 and Bax protein expression and decreased Bcl2 protein expression. Pretreatment with KRG protected against 4-HC-induced hair growth inhibition and premature catagen development. KRG also suppressed 4-HC-induced inhibition of matrix keratinocyte proliferation and stimulation of matrix keratinocyte apoptosis. Moreover, KRG restored 4-HC-induced p53 and Bax/Bcl2 expression. Conclusion: Overall, our results indicate that KRG may protect against 4-HC-induced premature catagen development through modulation of p53 and Bax/Bcl2 expression.

About 20% of non-Hodgkin' lymphoma occur in the extra-nodal region in the head and neck area and more than half of extra-nodal lymphoma in the head and neck area involves the Waldeyer' ring. Malignant lymphoma arising in the parotid glands are relatively rare, although 90% of all salivary gland lymphomas, appear in parotid gland and are classified as extranodal non Hodgkin' lymphoma. We experienced one rare case of non-Hodgkin' lymphoma in the right parotid gland, with a painless swelling of the cheek region as the chief complaint. We treated with CHOP(cyclophosphamide, $750mg/m^2$ i.v. day1 ; doxorubicin, $50mg/m^2$ i.v. day 1 ; vincristine, $1.4mg/m^2$ i.v. day 1;prednisone, $50mg/m^2$ orally days 1 to 5. repeat every 21 days) and Rituximab combination therapy. We aimed to report here one case of non-Hodgkin' lymphoma in the right parotid gland with review of literature.

In this research, the genotoxic effects of Kong-Jin-Dan(KJD), a polyherbal formula were evaluated using the mouse micronucleus test. KJD was administered once a day for 2 continuous days by oral gavage to male ICR mice at doses of 2000, 1000 and 500 mg/kg. Cyclophosphamide was used as a known genotoxic agent in a positive control. The appearance of a micronucleus is used as an index for genotoxic potential. In addition, the changes on the total white blood cells and differential counts on the lymphocytes, neutrophils, eosinophils, basophils and monocytes in the prepared blood smears were also conducted to observe the possible immunosuppress. The results obtained indicated that KJD shows no genotoxicity effects up to 2000 mg/kg dosing levels, but KJD shows slight increased trends in the blood total leukocyte numbers as pharmacological effects of immune stimulation. In addition, it is also considered that there were no problems from cytotoxicity of KJD tested in this study because the polychromatic erythrocyte ratio was detected as > 0.42 in all tested groups.

In anti-cancer therapies, radiotherapy and chemotherapy show a superior inhibition effect on cancer cell growth, but those are very toxic to normal tissues and organs. Particularly, drugs for neutropenia, one of chemotherapy agents, which suppress the function of bone marrow, are needed to be controlled in terms of their dosage and therapy period because of their side effect. Phellinus linteus polysaccharide (PL) has been reported to increase the number of splenocytes and bone marrow cells. PL has been shown to decrease the side effects of cyclophosphamide (CYC) treatment to the cancer patients. PL showed no effects in semisolid clonogenic assay, suggesting that PL doesn't contain substantial compounds to substitute for colony stimulating factors (CSFs). On the other hand, PL increased the expression of SCF, IL-3, GM-CSF, TPO genes. These results indicate that PL may promote the growth and proliferation of splenocytes and bone marrow cells through indirect or CSFs-dependent pathway, which may lead to a hematopoiesis.

The recogition that the vast majority of patients with small cell lung cancer have distant metastatic disease at the time of diagnosis lead to the use of systemic chemotherapy and consequent major improvement in survival, but recently evaulated treatment strategies, integration of large field chest irradiation with chemotherapy lead to the improved the local control and relapse free survival in limited SCLC. Therefore, it is logical to combine the two modalities in an effort to maximize the therapeutic effect. Authors performed the combination chemotherapy of CAV (Cyclophosphamide, Adriamycin, an6 Vincristine) and radiotherapy of primary tumor and regional lymphatics with prophylatic cranial irradiation in 42 patients of limited SCLC, from Mar. 1978 to Dec. 1982 Seoul National University Hospital. The results are as follows : 1. CR and PR after 2 cycles chemotherapy is $7\%$ and $43\%$, respectively however, subsequent response to radiotherapy is $38\%$ and $43\%$ in CR and PR. 2. Overall median survival peroid is 8.6 months. 3. 1 year and 2 years survival rate is $46.3\%$ and $20.5\%$, respectively. 4. Incidence of proven brain metastasis is $5\%$.

This study was performed to determine the effects of antimutagenicity from Barley (Hordeum vulgare). In Salmonella typhimurium reversion assay (In vitro test), the extract of Barley (Hordeum vulgare) inhibited mutagenic activity of 4-NQO and Trp-p-1 with 59 mix. in Salmonella typhimurium TA98 and TA100. In Micronucleus test (In vivo test), the methanol extract of Barley (Hordeum vulgare) inhibited micronucleus formation in bone marrow by cyclophosphamide. The $\beta$-glucan of Barley (Hordeum vulgare) showed inhibitory effects of 59-77% in mutagenic activity of 4-NQO by Salmonella typhimurium TA100. The mutagenicity of Trp-p-1 with S9 mix. by Salmonella typhimurium TA98 showed inhibitory effects of 24-56%. The methanl extract (M) was fractionated with ether (MI), ethylacetate (M2), buthanol (M3) and water (M4). The Antimutagenicity of Trp-p-1 with 59 mix. by Salmonella typhimurium TA98 in Barley fraction showed the following: methanol extract (99.58%)>ether fraction (98.05%)>buthanol fraction (56.90%)>water fraction (56.72%)>ethyl acetate fraction (28.72%). Among them, ether fraction in TA 98 showed strong antimutagenicity effects (85.56%, 98.05%) against mutation induced by 4-NQO and Trp-p-1. As concentration of the methanol extract increased (1.25~5 g/kg/10 cc), micronucleus formation in bone marrow by chemical mutagen (CP) showed inhibitory effects of 50% (p< 0.05).

The effect of aflatoxin-contaminated corn on albino mice was investigated using the sperm morphology assay. Blood parameter levels including; total white blood cells (WBC), total red blood cells (RBC), packed cell volume (PCV), serum bilirubin (SB) and fasting blood sugar (FBS) were also determined in the tested mice. Test mice were exposed to aflatoxin-contaminated corn (contamination level of 100 ppb) for $1{\sim}4$ weeks while aflatoxin-free corn and cyclophosphamide were used as negative and positive controls, respectively. Sperm cells showed varieties of morphological abnormality when assessed after 5 weeks. The percentage frequencies of the negative and positive controls were 18.8% and 48.87%, respectively, while the percentage abnormalities for the 1, 2, 3 and 4 weeks exposures were 41.38%, 48.17%, 57.13% and 61.67%, respectively. PCV, WBC, total bilirubin and glucose level values of mice in all concentrations were higher and statistically significant as compared to the negative control values using Dunnett's test. Therefore, abnormal sperm cell induction is concentrationdependent such that continuous consumption of aflatoxin-contaminated corn is capable of negatively affecting spermatogenesis by inducing or increasing the frequency of morphologically abnormal sperm cells produced.
