Abstract
The concept of "blood stasis" - called yū xiě in Chinese, Oketsu in Japanese - is one of the unique pathophysiology of traditional medicine that originated in China and inherited in Korea and Japan. This concept is related to the multiple aspects of hemodynamic disorders brought on by quantitative and qualitative changes. It theorizes that the quantitative changes of "blood stasis" are related to peripheral circulatory insufficiency. When chronic qualitative changes of "blood stasis" produce stagnant blood that turns into a pathological product, it could cause inflammation and lead to organic changes. Trauma induced hematomas, that are considered to be a quantitative change of blood, are also a form of blood stasis. The basic medicine research on Keishibukuryogan (KBG)-a Japanese name in Traditional Japanese Medicine (Kampo) for one of the most common anti- "blood stasis" prescriptions, also known as gui-zhi-fu-ling-wan (GFW) in Chinese in Traditional Chinese Medicine (TCM)-indicated that the initiation of quantitative changes was closely related to loss of redox balances on endothelial function induced by oxidative stress. The following qualitative changes were related to coagulopathy, hyper viscosity; anti-platelet aggregation, lipid metabolism; a regulation of systemic leptin level and/or lipid metabolism, inflammatory factor; cyclooxygenase-1,2 (COX-1, 2), interleukin-6, 8 tumor necrosis factor-α, macrophage infiltration, hyperplasia, tissue fibrosis and sclerosis caused by transforming growth factor-β1 and fibronectin, the dysfunction of regulated cell deaths, such as, apoptosis, autophagy, ferroptosis and ovarian hormone imbalance. Clinically, KBG was often used for diseases related to Obstetrics and Gynecology, Endocrine Metabolism, Rheumatology and Dermatology. In this review, we give an overview of the mechanism and its current clinical application of KBG through a summary of the basic and clinical research and discuss future perspective.

Abstract
Chinese materia medica (CMM), including Chinese herbal, animal, and mineral medicine, has been widely researched in the past century for their biological and pharmacological activities. However, their mechanism and clinical efficacy studies did not always give expected results. For example, the most commonly used Chinese herb for menstrual disorders, Radix Angelicae sinensis, showed neither estrogenic nor progesteronic activity in laboratory and clinical studies. Its efficacy should not be denied simply based on such results, because it is mostly used together with other herbs in formulae. Moreover, its regulation on menstruation may take effect through other mechanisms, such as regulation of blood circulation. The key difference of Chinese medicine (CM) from conventional medicine is its unique holistic view on human body and diseases. CMM is mostly applied in clinic in the form of formulae. Study on individual CMM, simply using methods for development of conventional drugs, is unable to thoroughly reveal the power of CMM formulae. The reason may partly result from improper design due to the lack understanding about application principle of CMMs in CM, and/or to current lack of knowledge about the causes of some symptoms and diseases. This paper will introduce the importance of qi and blood in CM etiology and pathology, Zheng differentiation, formulation of CMMs, and explain why one formula can treat different diseases and one disease can be treated with different formulae. Examples in the paper will demonstrate that proper studies on Zheng and its corresponding clinically proven formulae could help scientists find new direction to explain and treat symptoms and diseases that so far modern medicine has been unable to, provided that the designer properly understands CM theories, etiology and pathology of CM, as well as modern medicine. Strategy suggestions about research methods for CMM and its formulae will be given at the end.

Effect of keishibukuryogan on endothelial function in patients with at least one component of the diagnostic criteria for metabolic syndrome: a controlled clinical trial with crossover design. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:359282.

Abstract
We evaluated the effect of keishibukuryogan (KBG; Guizhi-Fuling-Wan), a traditional Japanese (Kampo) formula, on endothelial function assessed by reactive hyperemia peripheral arterial tonometry (Endo-PAT2000) in patients with metabolic syndrome-related factors by controlled clinical trial with crossover design. Ninety-two patients were assigned to group A (first KBG-treatment period, then control period; each lasting 4 weeks, with about one-year interval) or group B (first control, then KBG-treatment). In forty-nine (27, group A; 22, group B) patients completing all tests, the mean value of the natural logarithmic-scaled reactive hyperemia index (L_RHI) increased and those of serum nonesterified fatty acid (NEFA), malondialdehyde, and soluble vascular cell adhesion molecule 1 decreased significantly during the KBG-treatment period, but not during the control period, and 4-week changes of L_RHI, NEFA, and malondialdehyde between the 2 periods showed significance. These results suggest that KBG has beneficial effect on endothelial function in patients with metabolic syndrome-related factors.

Abstract
An increasing death rate due to cardiovascular disease in patients with rheumatoid arthritis (RA) has been reported. Keishibukuryogan (KBG) is a traditional Chinese/Japanese (Kampo) formula that has been administered to patients with blood stagnation, e.g. thrombotic disease and atherosclerosis. The objective of this study was to evaluate the efficacy of KBG on disease activity and endothelial dysfunction in RA patients. Sixteen RA patients were enrolled and administered KBG (12 g per day) for 12 weeks in addition to continuing other drugs. The disease activity of RA was assessed by modified disease activity scores for 28 joints (DAS(28)). Plasma levels of adhesion molecules, soluble E-selectin (sE-selectin), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were evaluated. C-reactive protein (CRP), inflammatory cytokines (IL-1beta, IL-6 and TNF-alpha) and lipid peroxide (LPO) were also evaluated. Fourteen patients completed the study. The disease activity of RA, tender joint count, swollen joint count and DAS(28) decreased significantly. Among adhesion molecules, only sVCAM-1 decreased significantly. LPO also decreased significantly, whereas CRP and inflammatory cytokines remained unchanged. These results suggest that KBG has insufficient anti-inflammatory or immunomodulating effect but does have a beneficial effect on articular symptoms and a protective effect against endothelial dysfunction in RA patients.

Abstract
OBJECTIVE To examine the effects of keishibukuryogan (TJ-25)-a medicine of the Kampo tradition (the Japanese adaptation of Chinese herbal medicine)-on middle-aged women with high blood pressure. METHODS The records of 77 peri- and postmenopausal women with high-normal blood pressure or hypertension were analyzed retrospectively. The women had participated in the Systematic Health and Nutrition Education Program at the Tokyo Medical and Dental University in Tokyo, Japan, and had received education only (controls; n = 47) or education and treatment with TJ-25 (n = 30). RESULTS The baseline characteristics of the 2 groups were comparable. After approximately 6 months, women in the TJ-25 group showed significant reductions in their systolic blood pressure (from 148.4mm Hg to 134.8mm Hg), diastolic blood pressure (from 89.7 mm Hg to 83.7 mm Hg), pulse rate (from 79.5 beats/min to 73.5 beats/min), and resting energy expenditure (from 1552 kcal/day to 1373 kcal/day). Several menopausal symptoms including perspiration, difficulty in initiating sleep, nonrestorative sleep, and headaches/dizziness were also improved. In addition, women in the TJ-25 group had increased health-related quality of life scores in the domains of physical health and life satisfaction. CONCLUSION TJ-25 alleviates menopausal symptoms and concurrently lowers the blood pressure of middle-aged women with high blood pressure.

Abstract
The effects of keishibukuryogan on the early stage of progressive renal failure were examined in rats subjected to 5/6 nephrectomy. Keishibukuryogan, one of the traditional herbal formulations, was given orally at a dose of 1% (w/w) and 3% (w/w) in chow. Administration of keishibukuryogan was started at 1 week after 5/6 nephrectomy and was continued for 4 weeks. At the end of the experiment, Azan staining did not reveal any severe histological changes in the kidneys of the nephrectomized rats. On the other hand, significant increases in mRNA expressions of transforming growth factor-β1 and fibronectin related to tissue fibrosis, as examined by Reverse Transcriptase-Polymerase Chain Reaction, were observed in nephrectomized rats, and they were significantly suppressed by 3% keishibukuryogan treatment. Against gene expressions related to macrophage infiltration, 3% keishibukuryogan treatment significantly suppressed osteopontin mRNA levels, and monocyte chemoattractant protein-1 and vascular cell adhesion molecule-1 mRNA levels showed a tendency to decrease, but without statistical significance. It was also observed that 3% keishibukuryogan attenuated serum urea nitrogen and urinary protein excretion levels. From these results, it was suggested that keishibukuryogan exerts beneficial effects that result in slowing the progression of chronic renal failure.

Abstract
The Kampo formula keishibukuryogan (KBG, Guizhifulingwan) is frequently used in traditional Japanese and Chinese medicine to treat several symptoms and manifests anti-inflammatory and scavenging effects. Nonalcoholic fatty liver disease (NAFLD) is a common manifestation of the metabolic syndrome and has the potential to evolve to liver cirrhosis through chronic inflammation and steatohepatisis (NASH). We have recently reported the KBG significant effectiveness on liver injury in a NASH animal model that prompted us to prescribe to KBG (TJ-25). We performed a retrospective study and reviewed the charts of outpatients who were prescribed KBG for 8-12 weeks due to non-liver-related symptoms (n= 11) over the past year to evaluate the clinical outcome. In six of these cases, biochemical and ultrasound signs of NAFLD were observed. KBG led to a significant reduction in liver injury tests and blood cholesterol but had no effects on body weight in all NAFLD cases. Further, liver tests and lipid profiles returned to baseline values when KBG treatment was stopped. On the basis of data on a small number of subjects, we suggest that the use of KBG is a safe complementary treatment in patients with NAFLD. While it is unlikely that Kampo formulas may substitute the current nutritional approaches to the metabolic syndrome, future studies should address the possibility of an additive effect, possibly through anti-inflammatory mechanisms.

Abstract
Keishibukuryogan, one of the traditional herbal formulations, is used clinically to improve blood circulation. In this study, we examined the effects of keishibukuryogan on glucose and lipids metabolism in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, an animal model of type 2 diabetes. Forty-five-week-old male OLETF rats were divided into three groups: diabetic control rats given a standard chow; diabetic rats given keishibukuryogan (3%, w/w in chow); diabetic rats given pioglitazone (0.01%, w/w in chow). Oral administration of keishibukuryogan produced significant improvement against impaired glucose tolerance. On the other hand, fasting serum glucose and insulin levels, and the homeostasis index of insulin resistance did not change by keishibukuryogan treatment. Against lipid parameters, keishibukuryogan significantly lowered serum total cholesterol and triglyceride levels, and the hepatic total cholesterol level. Keishibukuryogan treatment also significantly reduced the serum leptin level, but it had no effect on the serum adiponectin level. Additionally, keishibukuryogan showed significant effects on epididymal adipose tissue by decreasing the size of fat cells and on skeletal muscle by reducing TNF-alpha protein content. From these results, it was suggested that keishibukuryogan exerts beneficial effects on the features associated with type 2 diabetes.

Abstract
Data on the efficacy of herbal compounds are often burdened by the lack of appropriate controls or a limited statistical power. Treatments to prevent the progression of non alcoholic fatty liver disease (NAFLD) to steatohepatitis (NASH) remain unsatisfactory. A total of 56 rabbits were arrayed into 7 groups fed with standard rabbit chow (SRC), SRC with 1% cholesterol, or each of the five experimental treatments (Kampo formulas 1% keishibukuryogan [KBG], 1% orengedokuto [OGT], and 1% shosaikoto [SST]; vitamin E [VE]; or pioglitazone [PG]) in a 1% cholesterol SRC. We analyzed changes after 12 weeks in plasma and liver lipid profiles, glucose metabolism, adipocytokines, oxidative stress, and liver fibrosis. Data demonstrated that all five treatments were associated with significant amelioration of lipid profiles, oxidative stress, and liver fibrosis compared to no supplementation. KBG was superior to VE and PG in the reduction of liver total cholesterol ( P < 0.01) and lipid peroxidase levels ( P < 0.05), urinary 8-hydroxy-2′-deoxyguanosine ( P < 0.05), hepatic α-smooth muscle actin positive areas ( P < 0.01) and activated stellate cells ( P < 0.01). In conclusion, there was a statistically significant benefit of Kampo formulas (KBG in particular) on a dietary model of NAFLD/NASH. Future studies need to be directed at the mechanisms in the treatment of NASH.

Abstract
It is known that rheumatoid arthritis (RA) accelerates atherosclerosis. Further, the soluble form of vascular adhesion molecule-1 (VCAM-1) is known as a predictive marker of atherosclerosis in RA patients. We reported that keishibukuryogan, one of the Kampo formulas, improved articular symptoms and decreased soluble VCAM-1 in patients with RA. In adjuvant-induced arthritis (AIA) rats, an animal model of RA, it is known that endothelial function is injured by inflammation. So, we investigated the effect of keishibukuryogan on endothelial function in AIA rats. Lewis rats were divided into control, AIA control, and AIA with keishibukuryogan groups. The AIA with keishibukuryogan group was fed 3% keishibukuryogan contained in normal chow. On day 25 after injection of Mycobacterium butyricum, endothelium-dependent relaxation by acetylcholine in the AIA control group was suppressed, but it was improved in the AIA with keishibukuryogan group. The contractions by xanthine/xanthine oxidase in both AIA rats increased, but that in keishibukuryogan decreased compared to the AIA control group. Plasma levels of lipid peroxide increased in the AIA control group, but keishibukuryogan decreased these levels. Plasma levels of nitric oxide (NO) increased in both AIA groups. The expressions of endothelial NO synthase, inducible NO synthase and VCAM-1 of thoracic aorta were investigated by western blotting. These expressions increased in the AIA control group, but were restricted in the AIA with keishibukuryogan group. We considered that keishibukuryogan protected the endothelial function of AIA rats mainly by its anti-oxidative effect.

Abstract
OBJECTIVES Kampo (Japanese traditional herbal) medicines are now ethically used in Japan as pharmaceutical grade prescription drugs. However, there are distinct groups of responders and non-responders to Kampo medicines. We searched for biomarker candidates to discriminate responders from non-responders to keishibukuryogan (KBG); one of the most frequently used Kampo medicines. DESIGN AND METHODS A combination of SELDI technology and a decision tree analysis with proprietary developed bioinformatics tools was applied to 41 (32 for tree construction and 9 for validation test) plasma samples obtained from rheumatoid arthritis (RA) patients. A candidate biomarker protein was identified using LC-MS/MS. RESULTS The constructed tree with measurable reliability contained only a single peak which was identified as haptoglobin alpha 1 chain (Hpalpha1). CONCLUSION Hpalpha1 is a biomarker candidate for discriminating responders from non-responders to KBG treatment for RA. The present results may open the way to the establishment of "evidence-based" complementary and alternative medicine.

Abstract
Keishibukuryogan, one of the traditional herbal formulations, is used clinically to improve blood circulation. It consists of the following five crude drugs: Cinnamomi Cortex, Poria, Moutan Cortex, Persicae Semen and Paeoniae Radix. In this study, the effects of keishibukuryogan against renal damage in spontaneously diabetic WBN/Kob rats were examined. Oral administration of keishibukuryogan significantly attenuated urinary protein excretion and serum creatinine levels. It did not affect body weight loss and blood glucose levels, but it suppressed renal and hepatic weights of WBN/Kob rats. Keishibukuryogan also reduced fibronectin and transforming growth factor beta(1) (TGF-beta(1)) protein expression in the renal cortex. Furthermore, lipid peroxidation levels in both kidney and liver were significantly lower than those of untreated control WBN/Kob rats. Urinary excretion of 8-hydroxy-deoxyguanosine was suppressed by keishibukuryogan treatment. These results suggest that keishibukuryogan reduces oxidative stress by hyperglycemia, and that it protects renal function and suppresses fibronectin deposition induced by TGF-beta(1) production in WBN/Kob rats.

Abstract
Previous studies revealed that Guizhi-Fuling-Capsules (GZFLC), a traditional Chinese medical (Kampo) formulation composed of five kinds of medicinal plants, Cinnamomum cassia BLUME (Cinnamomi Cortex), Paeonia lactiflora PALL. (Peonies Radix), Paeonia suffruticosa ANDREWS (Moutan Cortex), Prunus persica BATSCH (Persicae Semen), and Poria cocos WOLF (Hoelen), exerts a protective effect against vascular injury and has a protective effect against glutamate- or nitro oxide-mediated neuronal damage. In the present study, the effect of GZFLC in a rat in vivo model of focal cerebral ischemia and reperfusion was investigated. Administration of GZFLC (0.3 and 0.9 g/kg, p.o.) after focal cerebral ischemia significantly decreased brain infarction and water contents in rats subjected to 2-h ischemia followed by 24-h reperfusion from 31.72 +/- 2.49%, 84.76 +/- 1.63% in the model group to 17.31 +/- 3.66%, 82.51 +/- 1.36% and 8.30 +/- 3.73%, 81.35 +/- 1.73%, respectively. Furthermore, analysis of inflammatory cytokines in ischemic brain showed that GZFLC treatment significantly down-regulated expressions of pro-inflammatory cytokines including interleukin (IL)-1beta and tissue necrosis factor-alpha and markedly up-regulated expressions of anti-inflammatory cytokines IL-10 and IL-10R both in mRNA and protein levels. The serum levels of these inflammatory cytokines were also regulated the same way. These results suggested that GZFLC may be beneficial for the treatment of brain ischemia-reperfusion injury partly due to its anti-inflammatory properties.

Abstract
BACKGROUND The number of patients suffering from metabolic syndrome is increasing rapidly. Metabolic syndrome causes severe pathological changes in various organs, including the liver, and its main phenotype is nonalcoholic fatty liver disease (NAFLD). NAFLD has a broad spectrum ranging from simple fatty change to severe steatohepatitis with marked fibrosis. Recently, several experimental animal models for NAFLD have been proposed. However, most were established by rather artificial conditions such as genetic alteration. In the present study, we tried to establish a unique animal model mimicking some of the physiopathological features of NAFLD using high-cholesterol-fed rabbits. METHODS Male rabbits fed with standard rabbit food containing 1% cholesterol for 8 weeks and 12 weeks were compared to controls (six rabbits/group). The weight of food was strictly restricted to 100 g/rabbit per day. RESULTS Body weights and fasting plasma insulin levels showed no significant differences among the groups. In contrast, characteristic fine fibrosis was extended from perivenular to pericellular areas, and microvesicular fatty change with ballooning degeneration was observed in perivenular areas in livers of the cholesterol-fed rabbits. Increase of serum cholesterol level, activation of hepatic stellate cells, and exposure to oxidative stress were also recognized. CONCLUSIONS Cholesterol-fed rabbits share several physiopathological features of NAFLD. Because this model did not show insulin resistance or obesity, it may be useful for elucidating the mechanism of NAFLD related mainly to hyperlipidemia.

Abstract
In this study, we examined whether the Kampo formulas Oren-gedoku-to (OGT, Huanglian-jie-du-tang in Chinese) and Keishi-bukuryo-gan-ryo (KBG, Gui-zhi-fu-ling-wan in Chinese) could prevent the progression of atherosclerosis in cholesterol-fed rabbit, an animal model for hypercholesterolemia in vivo. Twenty-four male Japanese white rabbits (2 kg body weight) were divided into four groups. The control group was fed standard rabbit chow containing 1% cholesterol, the OGT group was fed standard rabbit chow containing 1% cholesterol and 1% OGT, the KBG group was fed standard rabbit chow containing 1% cholesterol and 1% KBG, and the vitamin E group was fed standard rabbit chow containing 1% cholesterol and vitamin E (450 mg/1000 g). All four groups were kept on these diets for 8 weeks. At the end of the experiments, the percentage of surface area of the total thoracic aorta with visible plaque was significantly reduced in the OGT and KBG groups. The serum thiobarbituric acid reactive substances of the vitamin E group showed a significantly low value compared with the control group, whereas the serum lipid peroxide levels of the OGT and KBG groups were considerably lower than that of the control groups as well as that of the vitamin E group. Furthermore, the urinary 8-hydroxydeoxyguanosine levels of the OGT and KBG groups were considerably lower than that of the vitamin E group. These results suggest that OGT and KBG prevent the progression of atheromatous plaque by creating a sounder antioxidant defense system than vitamin E.

Abstract
Geiji-Bokryung-Hwan (GBH) was studied on antiplatelet activity in human platelet suspensions. GBH consists of the 5 herbs Cinnamomi Ramulus, Poria Cocos, Mountan Cortex Radicis, Paeoniae Radix, and Persicae Semen, which have been used in herbal medicine for thousands of years for atherosclerosis. The mechanism involved in the antiplatelet activity of GBH in human platelet suspensions was investigated. GBH inhibited platelet aggregation and Ca2+ mobilization in a concentration-dependent manner without increasing intracellular cyclic AMP and cyclic GMP. GBH had no inhibitory effect on thromboxane B2 (TXB2) production in cell-free systems. Collagen-related peptide (CRP)-induced Ca2+ mobilization is regulated by phospholipase C-2 (PLC-gamma2) activation. We evaluated the effect of GBH on tyrosine phosphorylation of PLC-gamma2 and the production of inositol-1,4,5-trisphosphate (IP3). GBH at concentrations that inhibited platelet aggregation and Ca2+ mobilization had no effects on tyrosine phosphorylation of PLC-gamma2 or on the formation of IP3 induced by CRP. Similar results were obtained with thrombin-induced platelet activation. GBH inhibited platelet aggregation and Ca2+ mobilization induced by thrombin without affecting the production of IP3. We then evaluated the effect of GBH on the binding of IP3 to its receptor. GBH at high concentrations partially blocked the binding of IP3 to its receptor. Therefore, the results suggested that GBH suppresses Ca2+ mobilization at a step distal to IP3 formation. GBH may provide a good tool for investigating Ca2+ mobilization.

Abstract
Keishi-bukuryo-gan (Gui-Zhi-Fu-Ling-Wan) (KBG) is a traditional Chinese/Japanese medical (Kampo) formulation that has been administered to patients with "Oketsu" (blood stagnation) syndrome. In the process of neuronal cell death induced by brain ischemia, excessive generation of nitric oxide (NO) free radicals is implicated in the neurotoxicity. In the present study, we examined the protective effects of KBG and its constituent medicinal plants against NO donors, sodium nitroprusside (SNP) and 2,2'-(hydroxynitrosohydrazino)bis-ethanamine (NOC18)-induced neuronal death in cultured rat cerebellar granule cells (CGCs). MTT assay showed cell viability to be significantly increased by the addition of KBG extract (KBGE) (100 microg/ml), Cinnamomi Cortex extract (CCE) (3, 10 and 30 microg/ml), Paeoniae Radix extract (PRE) (100 microg/ml) and Moutan Cortex extract (MCE) (10 and 30 microg/ml) compared with exposure to SNP (30 microM, 24 h) only. Also, cell viability was significantly increased by the addition of KBGE (100 and 300 microg/ml), CCE (30 and 100 microg/ml), PRE (100 and 300 microg/ml) and MCE (30 and 100 microg/ml) compared with exposure to NOC 18 (100 microM, 48 h) only. Persicae Semen extract and Hoelen extract did not protect against NO donor-induced neuronal death. These results suggest that KBG has protective effect against NO-mediated neuronal death in cultured CGCs and that it is derived from Cinnamomi Cortex, Paeoniae Radix and Moutan Cortex.

Abstract
Keishi-bukuryo-gan (Gui-zhi-fu-ling-wan) is a formula used for the improvement of blood circulation. Recently it has often also been used for arteriosclerosis. One of the mechanisms involved is thought to be the improvement of endothelial dysfunction, but the details are still unclear. In this study, the effect of Keishi-bukuryo-gan on vascular function and hemorheological factors in spontaneously diabetic (WBN/kob) rats was studied. Rats were given Keishi-bukuryo-gan in chow for 30 weeks. Body weight, blood glucose, endothelium-dependent/-independent relaxation, vasocontraction by free radical-induced and contractive prostanoids, triglyceride, advanced glycation endproduct, lipid peroxides, serum NO2-/NO3- and blood viscosity were measured. The results indicated that Keishi-bukuryo-gan caused a decrease in endothelium-dependent relaxation by acetylcholine to become significantly increased, and vasocontraction induced by free radicals and contractive prostanoids was significantly decreased. Furthermore, serum NO2-/NO3- and blood viscosity were significantly decreased. From these results, it was supposed that Keishi-bukuryo-gan exerted a protective effect on the endothelium. The WBN/kob rat is a useful study model for the complications of human diabetes, and Keishi-bukuryo-gan showed a protective effect against vascular injury in the susceptible rat.

Abstract
Formerly, we have reported that keishi-bukuryo-gan prevents the progression of atherosclerosis in cholesterol-fed rabbits and inhibits the free radical-induced RBC haemolysis in rats. The present study was performed to investigate how keishi-bukuryo-gan (KBG) inhibits the early stage of atherosclerosis. Plasma lipid concentration and hydroxyl radical generation during respiratory burst in neutrophils were evaluated at the start and end of the study. The protective effect of KBG against endothelium disorder due to hypercholesterolaemia was examined. Twelve male Japanese white rabbits (2 kg body weight) were divided into two groups. Group A (n = 6) was fed standard rabbit chow containing 1% cholesterol for 4 weeks. Group B (n = 6) was fed standard rabbit chow containing 1% cholesterol and 1% KBG for 4 weeks. In the plasma lipid concentration, only the lipid peroxide concentration of group A was significantly higher than that of group B. At the end of the study, DMPO-OH, the spin-trapped adduct of hydroxyl radicals generated by neutrophils, was increased in both groups, and this increase was marked in group B. Endothelium-dependent vasodilatation by acetylcholine increased significantly in group B compared with group A. Thus, KBG protects the vascular endothelium function by its antioxidative effect and by inhibiting the release of free radicals from neutrophils in vivo.

Abstract
Keishi-bukuryo-gan (KBG) prevents the progression of atherosclerosis in cholesterol-fed rabbits by its antioxidative effect. The present study was to test our hypothesis that ingestion of KBG would protect red blood cell (RBC) membranes from free radical induced oxidation if polyphenolic antioxidants in KBG could be absorbed and circulated in the blood. When incubated with a RBC suspension, KBG and four of five herb medicines constituting KBG provided strong protection for RBC membranes against haemolysis induced by 2,2-azo-bis (2-amidinopropane) dihydrochloride (AAPH), an azo free radical initiator. The inhibitory effect was dose dependent at concentrations of 100-1000 microg/mL. Furthermore, the ingestion of 200 mg of KBG was associated with a significant decrease in susceptibility of RBC to haemolysis in rats.
