  • This study was carried out to investigate safety evaluation of IGEs separated and refined from bovine milk and commercial recombinant human IGFs. In order to evaluate toxicity of these samples, acute toxicity test and short term toxicity test were investigated with IGF-I separated and refined from colostrum and commercial recombinant human IGF-I from R&D systems company. for acute toxicity test, we selected recombinant human IGF-I from R&D systems company and establish one control group and three dose-level groups(0, 10, 20 and 50 $\mu\textrm{g}$ per rat). We have intravenously injected tail of rats with selected sample once. After 20 days, pathological cellular tissue analyses were investigated with liver, kidney and spleen of 12 rats in all test groups. However, Morbid tissue and abnormal statistical results were not discovered in all cellular tissues. For short term toxicity test, we selected IGF-I separated and refined from colostrum and establish one control group and three dose-level groups(0, 5, 10 and 15 $\mu\textrm{g}$/day per rat). Rats were orally injected with selected sample once a day during two weeks. After short term toxicity test period, Pathological cellular tissue analyses were investigate with liver, kidney and spleen of 12 rats in all test groups. However, Morbid tissue and abnormal statistical results were not discovered in all cellular tissues. These results suggest that IGF-I treated groups show no significant toxicological findings with changes of body weight, food consumption, water consumption, and pathological findings compared with control groups.

  • Care of people with severe disabilities requires care throughout their life cycle compared to non-disabled families. For this reason, carers of severely handicapped families are highly likely to have negative feelings throughout the family as well as daily stress. Disabled families also have a high rate of experiencing difficulties between non-disabled children or married couples in life centered on the disabled. In particular, the rapid aging in Korea affects the lives of the elderly disabilities along with the aging of the caregivers. The study explored alternatives to realistic support through the past and present experiences of caregivers with disabilities through qualitative research methods, and derived hopes and expectations for the future as follows.First, after confirming the disability for infants and toddlers with disabilities, information about the support system or system is provided from the rating agency. Second, providing "customized care support" suitable for the type of disability or individual characteristics at the social, political, institutional, and economic levels. Third, the provision of programs for non-disabled children and the provision of healing programs only for families with disabilities or those with disabilities. Fourth, the provision of spaces and programs that provide rest and rest for adults with disabilities. Fifth, the application of a long-term care system for the elderly reflecting the aging age of the disabled and institutionalization of community care for the disabled. The research is meaningful in that it presents discussion points for improving the quality of life of adults and the elderly with disabilities.

  • Bone marrow toxicity is a side effect of chemotherapy with anticancer drugs or the exposure to chemicals, such as benzene. When myelotoxicity occurs, the number of white blood cells decreases, which reduces immune functioning and increases the risk of infection or the development of tumors. Angelica gigas Nakai extract (AGNEX) and green coffee bean extract (GCBE) have many effects, such as anti-cancer and antioxidant effects, as well as effects on the immune functioning. In this experiment, the preventive effect of AGNEX and GCBE against benzene-induced bone marrow toxicity was confirmed in Sprague Dawley rats (SD rats) in vivo. Benzene (1 ml/kg mixed with corn oil 1:1) was intraperitoneally administered to SD rats (six weeks, N = 9/group) once a day, and AGNEX (12 mg/kg) and GCBE (6, 12, and 24 mg/kg) were administered orally daily for five weeks. To determine the preventive effect, AGNEX (12 mg/kg) and GCBE (6, 12, and 24 mg/kg) were administered orally before the administration of benzene. Consequently, AGNEX 12 mg/kg and GCBE 12 mg/kg were effective at reducing leukocytes and lymphocytes, specifically granulocyte. Additionally, the treatment also showed protective effects specifically on spleen and liver weight changes and spleen damage. Through this protective effect, AGNEX and GCBE were confirmed to prevent bone marrow toxicity by enhancing the functioning of the immune system.

  • We performed this study to determine the effect of green tea on jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells of mice irradiated with high and low dose of gammairradiation. The radioprotective effect of green tea was compared with the effect of diethyldithiocarbamate (DDC). Jejunal crypts were protected by pretreatment of green tea (p<0.01). Green tea administration before irradiation resulted in an increase of the formation of endogenous spleen colony (p<0.05). The frequency of radiation-induced apoptosis in intestinal crypt cells was also reduced by pretreatment of green tea (p<0.05). The radioprotective effect on jejunal crypts and apoptosis in the DDC treated group appeared similar to those in the green tea treated groups. Treatment with DDC showed no significant modifying effects on the formation of endogenous spleen colony. These results indicated that green tea might be a useful radioprotector, especially since it is a relatively nontoxic natural product. Further studies are needed to characterize better the promotion nature of green tea and its components.

  • The present study aimed to develop new physiologically active ingredients from Angelica gigas. The polysaccharides purified from A. gigas, AGE-2c-I, showed potent anti-complementary activity in a dose-dependent manner. C3 activation products were identified through crossed immuno-electrophoresis using anti-human C3 antibodies and the anti-complementary activity of AGE-2c-I under Ca++-free conditions suggests that AGE-2c-I may induce complementary activation via both alternative and classical pathways. In addition, AGE-2c-I augmented the production of various cytokines, such as interleukin (IL)-6, IL-10, IL-12, and tumor necrosis factor-α, by peritoneal macrophages. Furthermore, intravenous (i.v.) administration of AGE-2c-I dose-dependently enhanced natural killer cell cytotoxicity against YAC-1 lymphoma. In experimental lung metastasis, prophylactic i.v. administration of AGE-2c-I inhibited lung metastasis by 58% at 100 ㎍/mouse. From the above results, we suggest that AGE-2c-I purified from A. gigas has potent immune system-stimulating activities, and is a potentially promising food ingredient beneficial to human health.

  • Purpose: This prospective study was performed to evaluate the usefulness of preoperative radioimmunoscintigraphy and intraoperative scintimetric examination (radioimmunoguided surgery: RIGS) using $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment. Materials and Methods: Nineteen patients with rectal cancer underwent preoperative whole body planar scintigraphy at 4 hours after injection of $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment and SPECT imaging at 18 hours. Surgical operation was performed at 24 hours after injection. During laparotomy, radioactivities from intraabdominal viscera were measured by gamma probe. The radioactivities from excised tumor and lymph nodes were also measured and compared with pathology. Results: All nineteen patients were confirmed to have adenocarcinomas in the rectum. Twenty-seven of 97 excised lymph node groups had metastasis and 2 patients had liver metastasis in pathology Preoperative radioimmunoscintigraphy detected primary tumors in 11 patients (sensitivity 55%) and it could not detect any lymph nodes or liver metastasis. All patients showed high radioactivity in the kidneys, liver, spleen, and major vessels in intraoperative measurement by gamma probe, and tumor activity was not discriminated from background activity However, radioactivity from excised tumor was higher than normal rectum (T/B ratio; $3.47{\pm}2.25$). When excised lymph node activity/background activity ratio >1.5 was considered as positive criteria of metastasis, sensitivity, specificity, positive and negative predictive values were 78.6%, 73.9%, 55.0% and 89.5%, respectively. Conclusion: Radioimmunoscintigraphy using $^{99m}Tc-anti-CEA\;F(ab')_2$ has no additional value for preoperative staging and use of early RIGS using $^{99m}Tc-anti-CEA\;F(ab')_2$ is inappropriate. For early RIGS using $^{99m}Tc$ labeled antibodies in rectal cancer patients, further development of more specific antibodies and methods to reduce background activity are needed.

  • The anti-stress effect by the treatment of vitamin C was investigated in this study. The treatment of ascorbic acid in the presence of $Cu^{2+}$ion induced strong time- and dose-dependent degradation of hitamine, and also the addition of histamine accelerated time-dependent decomposition of ascorbic acid in vitro. The treatment of ascorbic acid in $ODS^{od}/_{od}$rats, which cannot synthesize ascorbic acid, significantly decreased the urinary histamine. The protreatment of ascorbic acid, dexamethasone and promethazine inhibited the lethal effect induced by immobilization stress, but that of dimethylsulfoxide did not. The addition of ascorbic and to a culture of spleen cells of $ODS^{od}/_{od}$rats significantly increased the Con A-dependent T lymphocyte proliferation.

  • Splenic metastasis from colon carcinoma are rare and usually occur in the presence of disseminated visceral metastasis. The liver is the most common site of metastatic spread from colon cancer. Several hypotheses have attempted to explain the low incidence of splenic metastasis. It should be difficult for colorectal cancer cells to reach the spleen through the portal venous system, in which the blood flow is usually from the spleen to the liver. Reticuloendothelial system or rhythmic contraction of the spleen may squeeze out the tumor in the spleen. The absence of afferent lymphatic to the spleen, phagocytic activity and humoral anticancer substances are considered to be other reason for low incidence of splenic metastasis. We report the case of $^{18}F-FDG$ PET/CT finding in a 70-year-old woman who develop isolated splenic metastasis of sigmoid colon cancer.

  • The effects of intravenous administration of of C. parvum on immune cells in mice were investigated. Significant delayed type hypersensitivity parvum was given intravenously before antigen sensitization. The depressed effect of C. parvum was completely abolished by treatment of cyclophosphamide. However, delayed type hypersensitivity was not depressed when C. parvum given after antigen. This depression is considered to be attributable to the generation of suppressor cells which were either suppressor T cell or C. parvum activated macrophage, because C. parvum inhibited the proliferation of S. typhimurium in vivo and also induced splenomegaly and hepatomegaly, known as manifestation of macrophage activation. Serum antibody titers were not significantly affected by C. parvum regardless of time of C. parvum administration.
