We performed this study to determine the effect of Bu-Zhong-Yi-Qi-Tang, as a prescription of traditional Oriental medicine, and its major ingredients on jejunal crypt survival, endogenous spleen colony formation, apopotosis in jejunal crypt cells, lethality and hematological change of mice irradiated with high and low dose of Y-radiation. Bu-Zhong-Yi-Qi-Tang administration before irradiation protected the jejunal crypts (p<0.0001), increased the formation of endogenous spleen colony (p<0.05) and reduced the frequency of radiation-induced apoptosis (p<0.05). The survival rate and mean survival time of the groups treated with Bu-Zhong-Yi-Qi-Tang within 30 days after the treatment were far better than the irradiation control group. In the experiment on the effect of ingredients of Bu-Zhong-Yi-Qi-Tang, the result indicated that the extract of Rensan (Panax ginseng), Danggui (Angelica sinensis), Shengma (Cimicifuga heracleifolia) and Chaihu (Bupleurum falcatnosa) might have a major radioprotective effect. Although the mechanisms of this inhibitory effect remain to be elucidated, these results indicated that BU-Zhong-Yi-Qi-Tang might be a useful radioprotector, especially since it is a relatively nontoxic natural product. Further studies are needed to characterize better the protective nature of Bu-Zhong-Yi-Qi-Tang extract and its ingredients.

먼저 OVA항원에 대해 특이적으로 증식반응을 나타내는 T세포주를 수립하였고, 수림된 세포주는 세포 표면 단백질이 CD4$^{＋}$CD8$^{-}$이며 IL-2와 IFN-${\gamma}$를 분비하는 Type I에 속하는 보조 T세포(Thl)인 것을 확인하였다. 보중익기탕의 total 분획은 OVA항원에 대해 특이적으로 반응하는 Thl세포의 증식반응을 증가시키는 효과를 나타내지 않았으며 고농도에서 오히려 증식반응을 억제하였다. 그러나, 보중익기탕의 polysaccharide 분획은 전반적 인 농도에서 T세포의 증식반응을 유의하게 증가시키는 효과가 있는 것으로 나타났다. 보중익기탕의 polysaccharide 분획을 첨가하였을 때 T세포의 IL-2 분비량은 대조군보다 약간 적었지만, IFN-${\gamma}$ 분비량은 대조군보다 증가하였다. 그리고, 분비된 IL-2와 결합하는 T세포의 IL-3 수용체 발현양도 증가하는 것으로 나타났다. 또한, 항원제시세포의 MHC class II의 발현양도 증가시켰다. 이상의 결과로 보중익기탕의 polysaccharide분획은 T세포의 IL-2수용체 발현양을 증가시키고, 항원제시세포의 MHC classs II의 발현양을 증가시켜서 T세포의 증식반응을 증가시키는것으로 생각된다 그리고 보중익기탕이 생체 면역반응에 미치는 보다 정확한 효과를 평가하기 위해서는 직접 살아있는 실험동물에 투여하는 in vivo 실험이 필요하다.

최근에 방사선 조사에 대해 방호효과를 가지는 것으로 알려진 보중익기탕의 골수세포 분화 유도 효과에 대해 관찰하였다. 시험관에서 골수세포를 배양했을 때, 배양시간(5일,10일)에 따라 대조군의 세포 수는 현저히 감소하였고, 보중익기 탕의 total 분획을 첨가하였을 때도 비슷한 결과를 얻었다. 그러나 polysaccaride 분획을 첨가하였을 때는 감소하는 세포수가 일정한수준에서 유지되며 더 이상 감노하지 않았다. 그리고 이들 세포가 어떤 종류의 세포인지를 유세포분석기로 분석한 결과, Pre-B세포의 특징적인 세포 표면 단백질인 CDl9와 CD40을 동시에 발현한 세포인 것이 확인되었다. 또한, 이들 세포는 분화과정 이 끝난 B세포가 분비하는 IgM 뿐만 아니라 IgG1, G2a, G3를 분비하였다. 이상의 결과 보중익기탕의 polysaccaride 분획에 골수세포가 B세포로 분화 증식하는 것을 유도하는 성분이 포함되어 있어 방사선 조사로 상해를 입은 조혈계에 대한 방호 효과를 나타내는 것으로 생각된다.

The purpose of this study reported here was to investigate the ability of Bu-Zhong-Yi-Qi-Tang (BZYQT), known to elevate hematopoietic functions, to protect mice undergoing treatment with whole body single gamma-irradiation. BZYQT was given (25 mg/kg B.W.) intraperitoneally at 36 and 12 hours before irradiation and 30 minute and 24 hours after irradiation. Recovery of neutrophil and lymphocyte counts was significantly stimulated by extract of BZYQT. Stimulated recovery by the extract from the BZYQT was also observed in thrombocyte. However, the anti-radiation effect of erythrocyte, hemoglobin and hematocrit was not as significant as that of leukocyte. Further studies are needed to better characterize the protective nature of BZYQT extract and its ingredients.

본 실험에서는 생쥐에서 분리한 골수 세포의 분화에 보중익기탕 추출물이 미치는 영향을 알아보았다. GM-CSF와 IL-3는 대식세포의 형성을 자극하는데 관여한다. 보중익기탕 추출물을 첨가하였을 때 GM-CSF와 IL-3로 분화하는 colony의 수를 증가시키는 것을 알 수 있었으며 anti-CD11b 항체로 염색한 결과 분화한 세포는 대식 세포의 특이적 세포표면 단백질 인 CD11b(Mac-1)를 발현하고 있었다. 또한 보중익기탕 추출물은 대식세포가 생산하는 IL-6와 일산화질소(nitric oxide)의 분비량도 증가시키는 것을 알 수 있었다. 이상의 실험 결과, 오래 전부터 전통 처방제로 사용되어온 보중익기탕 추출물은 대식세포의 분화와 증식을 유도하는데 효과가 있는 것으로 생각된다.

We performed this study to determine the late biological effect of gamma radiation and effect of Bu-Zhong-Yi-Qi-Tang (BZYQT), a prescription of traditional Oriental medicine, on radiation-induced late biological effect (survival, hematological change, carcinogenesis) of mice irradiated with 3 Gy of gamma-radiation. There were little difference in body weights between normal and irradiated mice. Survival rate were decreased in irradiated mice and the survival rate and mean survival time of the groups treated with BZYQT were far better than the irradiation control group. A significant elevation of total leukocyte or lymphocyte counts was seen at week 4 and 12 of the group treated with BZYQT. Stimulated recovery by the extract from BZYQT was also observed in thrombocyte. Main gross findings of irradiated mice were appeared as enlargement of spleen, thymus and liver, tumorous nodules of lung and cyst or mass of ovary. Microscopically, there were various findings including hematopoietic and lymphoid tumor, lung cancer, ovarian cancer and cancer of other lesions. BZYQT reduced the incidence of tumor development. Further studies are needed to characterize better the protective nature of ingredients and active compounds.

I researched clinically one patient with Hypothyroidism who was hospitalized in DongShin Univ Shunchun Oriental Hosp. from the 4th, November, 2000 to the 13th, December, 2000. The results were obtained as follows. 1. Hypothyroidism corresponds to edema of instep (浮腫), consumption (虛勞), infantile retardation of walking (行遲), retardation in speech (語遲), inactivity of Yang-Qi(결양증). It is caused to deficiency of both Qi and blood (氣血兩虛), insufficiency of Yang of the spleen and kidneys (脾腎陽虛), decline of the fire from the vital gate (命門火衰), deficiency of yang of the heart and kidneys (心腎陽虛) 2. In internal medication, it was thought that Yi qi bu xue tang(益氣補血湯). Shao yin ren Bu zhong yi qi tang(少陰人補中益氣湯), Jia wei ta bu tang (加味大補湯) were effective. 3. In acupunture therapy, zu san li(足三里), san yin jiao(三陰交), Ren ying (人迎), Fu tu (扶突), Tian tu(天突) were used frequently and in moxibustion therapy. qi hai(氣海), zhong wan(中脘). Guan yun(關元) were used for Hypothyroidism.

Background: Bu-Zhong-Yi-Qi-Tang (BZYQT) has long been used for the treatment of severe weakness caused by general fatigue, loss of appetite, or indigestion. The aim of this feasibility study is to assess the effectiveness and safety of BZYQT for the treatment of functional dyspepsia (FD) with spleen qi deficiency. Methods: This study will be conducted at a single center as a prospective, nonrandomized, nonblinded, single-arm feasibility study. A total of 30 participants diagnosed with FD in accordance with the Rome III criteria will be enrolled. All patients will receive BZYQT for 4 weeks. The primary outcome is the change in the Nepean Dyspepsia Index-Korean version (NDI-K) scores between the baseline and 4-week images. The secondary outcomes include the tongue coating thickness, blood parameters, and BZYQT Questionnaire score. The NDI-K score will be acquired four times, at Weeks 0 (baseline), 2 (during treatment), 4 (after treatment), and 8 (after follow-up). Written informed consent will be obtained from all study participants prior to enrollment. This study has been approved by the Institutional Review Board of Kyung Hee University Korean Medicine Hospital. This study protocol is registered with the national clinical trial registry of the World Health Organization International Clinical Trials Registry Platform. Results will be published in a journal and will be disseminated both electronically and in print. Discussion: The results of this study may serve as a guide for researchers seeking to effectively evaluate the effects of BZYQT.

A high performance liquid chromatographic (HPLC) method for the determination of glycyrrhizic acid was developed for the quality control of traditional herbal medicinal preparation Bu-Zhong-Yi-Qi-Tang (BZYQT), which is well-known herbal medicine used as tonic. RP-HPLC analysis was carried out using Capcell pak $C_{18}$ MG column $(5\;{\mu},\;150{\times}4.6\;mm)$ and a mobile phase consisting of acetonitrile and water containing 0.03% phosphoric acid (pH 2.46) at a flow rate of 1.0 ml/min. The optimum wavelength for the detection of the glycyrrhizic acid was found at 250 nm using diode-array UV/VIS detector. The glycyrrhizic acid in BZYQT shows good linearity $(r^2>0.999)$ in the range of $15\;{\mu}g/ml$ to 500 ${\mu}g/ml$. The limit of detection (LOD) was less than 5 ng and R.S.D for intra-day and inter-day reproducibility was less than 7%. The mean recovery of the glycyrrhizic acid was $97.3{\sim}113.0%$. These results suggest that the developed HPLC method is simple and efficient, and could be contributed for the quality control of commercial BZYQT products.
