        Due to recent increase in the number of elderly patients, there is a problem of nutritional imbalance and immune function in the elderly due to decreased ability to consume food. To solve these problems, this study was conducted to verify an immunityenhancing effect of Sagunja-tang porridge (SP) on cyclophosphamide (CPA)-induced immunosuppression using an animal model. Experimental groups were set as normal control, CPA-treated group, positive control group, and SP-treated groups (0.25%, 0.5%, 1.0%). Except for the normal control group, experimental groups were injected with 100 μL of CPA dissolved in 0.9% NaCl at a concentration of 150 mg/kg twice at the beginning of the experiment and 3 days later to induce immunosuppression. When spleen cell proliferation was analyzed, both B and T cells were decreased in the immunosuppressed group, but increased in test substance-treated groups in a concentration-dependent manner. To see the effect of improving immunity, levels of IgA known to protect the mucosal surface were measured. Higher levels of IgA were found in SP-low concentration (SL) and SP-middle concentration (SM) groups. These results suggest that using SP might be an effective way to improve nutritional imbalance and immune function in the elderly.

        Four-week repeated-dose toxicity of Misaengtang (MST) was evaluated according to Toxicity Test Guideline of Korea Food and Drug Administration using 6-week-old Sprague-Dawley rats. Based on the results of preliminary single-dose toxicity study, confirming safety up to an upper-limit dose, MST was dissolved in drinking water and orally administered at doses of 500, 1,000, or 2,000 mg/kg for 28 days. All doses including the upper-limit limited dose (2,000 mg/kg) of MST did not cause any abnormalities of rats, including mortality, clinical signs, body weight gain, feed/water consumption, necropsy findings, organ weights, hematology and blood biochemistry. Rather, high doses (1,000-2,000 mg/kg) of MST reduced the serum levels of alanine transaminase, aspartate transaminase, creatinine phosphokinase, lactate dehydrogenase and triglycerides, in addition to an increase in glucose, indicative of protective effects on hepatic and muscular injuries. Both maximum-tolerable dose and no-observed-adverse-effect level were not determined. The results indicate that long-term intake of high-dose MST might not induce general adverse-effects.
