Objectives: This study was investigated the protective effect of Spatholobi Caulis water extract against cadmium (CdCl2, Cd)-induced hepatic toxicity in rats. Methods: To induce acute hepatic toxicity, Cd (4 mg/kg body weight) was dissolved in normal saline and intravenously injected into rats. Then, the rats received either a vehicle or silymarin (100 mg/kg) or Spatholobi Caulis water extract (30, 50 mg/kg/day) for 3 days, and were exposed to a single injection of Cd 24 h after the last Spatholobi Caulis/vehicle treatment. Results: Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were significantly increased by Cd treatment. In contrast, pretreatment with Spatholobi Caulis reduced ALT, AST and LDH. Cd-intoxicated liver damage was significantly inhibited by treatment of Spatholobi Caulis 30 and 50 mg/kg at histopathological observations in the present study. Conclusions: These results can be considered as direct evidence that Spatholobi Caulis has favorable inhibitory effects on the Cd-intoxicated liver damages. The efficacy of Spatholobi Caulis 30 mg/kg shows similar effects to that of silymarin 100 mg/kg, and more favorable hepatoprotective effects were observed in Spatholobi Caulis 50 mg/kg as compared with silymarin 100 mg/kg against Cd-intoxicated hepatopathies in the present study.

Objectives : This study investigated whether the water extract of Spatholobi Caulis (SCE) has the ability to protect hepatocyte against oxidative stress induced by tert-butylhydroperoxide (tBHP) in vitro and $CCl_4$ in vivo. Methods : In vitro, HepG2 cells pre-treated with Spatholobi Caulis water extract (1, 3, 10, $30{\mu}g$/ml) for 12h and further incubated with tBHP ($100{\mu}M$) for the next 12h. Cell viability was assessed by MTT assay. In vivo, rats were orally administrated with the aqueous extract of Spatholobi Caulis (SCE; 50, 100 mg/kg) for 4 days and then, injected with $CCl_4$ 1 mg/kg body weight to induce acute liver damage. Results : Treatment with SCE inhibited cell death induced by tBHP, as evidenced by alterations in the levels of the proteins associated with apoptosis:SCE prevented a decrease in $Bcl_2$, and cleavage of poly(ADP-ribose)polymerase and pro-caspase-3. Moreover, SCE inhibited the ability of tBHP to generate $H_2O_2$ production, thereby restoring GSH content. Moreover, SCE treatments in rats effectively decreased liver injuries induced by a single dose of $CCl_4$, as evidenced by decreases in hepatic degeneration and inflammation as well as plasma alanine aminotransferase and lactate dehydrogenase activities. Consistently, treatments of SCE also protected liver in rats stimulated by $CCl_4$, as indicated by restoration GSH and prevention of MDA in the liver. Conclusions : SCE has the ability 1) to protect hepatocyte against oxidative stress induced by tBHP and 2) to prevent $CCl_4$-inducible acute liver toxicity. Present findings may be informative not only in elucidating the pharmacological mechanism of Spatholobi Caulis, but in determining its potential application for oxidative cellular damage in the liver.

The production of matrix metalloproteinases (MMPs) by the UV irradiated skin fibroblast and the degradation of exracellular matrix (ECM) by these enzymes is known as one of the main reasons of photoaging. In this study, to investigate the relationship between aging and Spatholobi caulis extract, we examined the effects of antioxidant, in vitro MMP inhibition and expression of UVA-induced MMP-1 in human dermal fibroblasts. Spathoiobi caulis extract was found to show scavenging activities of radicals and reactive oxygen species (ROS) with the $IC_{50}$ values of $45.81{\mu}g/ml$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and $3.11{\mu}g/ml$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. Spatholobi caulis extract inhibited the activities of MMP-1 in a does-dependent manner and the IC50 value calculated from semi-log plots was $31.96{\mu}g/ml$. Also, UVA induced MMP expression was reduced $74.66\%$ by treatment with Spatholobi caulis extract, and MMP-1 mRNA expression was reduced in a dose-dependent manner. Therefore Spatholobi caulis extract was able to significantly inhibit MMP expression in protein and mRNA level. All these results suggested that Spatholobi caulis extract may act as an anti-aging agent by antioxidation and reducing UVA-induced MMP-1 production.

Objectives : The present study was evaluated the protective roles of Spatholobi Caulis in hepatotoxic rats due to APAP overdose. Methods : In experiments, rats were orally administrated with the aqueous extract of Spatholobi Caulis (SCE; 50, 100 mg/kg) for 4 days and then, orally gavage with APAP (1.2 g/kg) to induce acute liver damage. Results : Oral injection of APAP caused severe hepatic injury. Plasma ALT, AST and LDH levels were significantly elevated, but SCE significantly decreased ALT, AST and LDH to the normal level. In histopathological analysis, peripheral hemorrhage around portal triads and central necrosis around central veins were founded after APAP treatment. However, these histopathological changes were recovered by SCE pretreatment. SCE also decreased the percentage of generative hepatic regions (%/$mm^2$ hepatic parenchyma), the numbers of inflammatory cells (cells/$mm^2$ hepatic parenchyma) and the number of degenerative hepatic cells (N/100 hepatic cellls) which were significantly elevated after APAP injection. Furthermore, SCE down-regulated the contents of hepatic MDA and up-regulated hepatic GSH. SCE also inhibited the decrease in the expression of pro-caspase-3 by APAP treatment. Conclusions : Collectively, these data indicate that SCE protected APAP-induced hapatic damages through antioxidative and anti-apoptotic process. These findings the significant therapeutic potential of SCE during APAP-induced liver injury.

Objectives : This study was undertaken to investigate the hepatoprotective effect of Spatholobi Caulis water extract (SC) to thioacetamide (TAA)-induced acute liver injury (ALI) in rats. Methods : The rats were injected intraperitoneally with TAA (200 mg/kg body weight) and orally administered SC (100 or 200 mg/kg b.w.) daily for 3 days. Liver biomarkers were assessed by serum glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and ammonia levels. Malondialdehyde (MDA) was measured both serum and liver tissue. In addition, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, anti-oxidant, and inflammation-related proteins were investigated by western blot analysis. Histological examination further confirmed though hematoxylin and eosin stain. Results : The SC treatment reduced liver function markers like GOT and GPT and also remarkably decreased ammonia level. Moreover, the elevated MDA level in TAA-induced group was significantly reduced by SC treatment. NADPH oxidase expression associated with oxidative stress including NOX2, NOX4, and p47phox markedly inhibited by SC administration. SC treatment exerted anti-oxidant effect through the increase of anti-oxidant enzyme including superoxide dismutase (SOD), Catalase, and heme oxygenase-1 (HO-1). The protein expressions of inflammatory cytokines such as tumor necrosis factor-�� (TNF-��), IL-6, and IL-1�� induced by nuclear factor-kappa B (NF-��B) activation were modulated through blocking the phosphorylation of inhibitor of nuclear factor ��B�� (I��B)��. SC treatment also improved histological alterations. Conclusion : These findings suggested that SC administration may be a potential candidate for the prevention or treatment of ALI.
