The effect of alcoholic extracts of Costus specious (Family: Zingiberaceae) was evaluated in experimental models of pain and inflammation. Oral administration of 100, 200 and 300 mg/kg of C. specious extracts were used for the above study. Crude extracts of C. specious (300 mg/kg dose) showed maximum time needed for the response against thermal stimuli ($7.242\;{\pm}\;0.532\;s$) which is comparable to diclofenac sodium ($8.471\;{\pm}\;0.25\;s$) in the hot plate test. The MPH (Maximum Possible Analgesia) has been found to be 14.285 for 300 mg/kg dose of the crude extract while the MPH for diclofenac was 15.857 after 60 min of administration in the hot tail-flick method. The crude extract at 300 and 200 mg/kg doses showed significant reduction in acetic acid induced writhings in mice with a maximum effect of 59.661% reduction at 300 mg/kg dose which is comparable to standard diclofenac sodium (73.4%). Alcoholic extract of C. specious showed significant inhibition in serotonin and egg albumin induced hind paw oedema in rats at 100, 200 and 300 mg/kg of the crude extracts respectively (Serotonin induced edema 44.22; 53.75; 58.51%; egg albumin induced edema - 41.317; 53.892; 59.880% inhibition after 4 h respectively). The antiinflammatory effects showed by the extract were comparable to that of standard indomethacin 5 mg/kg (Serotonin induced edema 77.56%; egg albumin induced edema 77.844% inhibition after 4 h). These results suggest that the extract possesses both the anti-inflammatory and analgesic activity on mice and rat model.

Nitric oxide (NO) produced in large amounts by inducible nitric oxide synthase (iNOS) is known to be responsible for the vasodilation and hypotension observed in septic shock and inflammation. Inhibitors of iNOS, thus, may be useful candidate for the treatment of inflammatory diseases accompanied by the overproduction of NO. We prepared alcoholic extracts of woody plants and screened the inhibitory activity of NO production in lipopolysaccharide (LPS)-activated macrophages after the treatment of these extracts.

Pharmacological and preventive properties of Petroselinum sativum seed extracts are well known, but the anticancer activity of alcoholic extracts and oil of Petroselinum sativum seeds on human breast cancer cells have not been explored so far. Therefore, the present study was designed to investigate the cytotoxic activities of these extracts against MCF-7 cells. Cells were exposed to 10 to $1000{\mu}g/ml$ of alcoholic seed extract (PSA) and seed oil (PSO) of Petroselinum sativum for 24 h. Post-treatment, percent cell viability was studied by 3-(4, 5-dimethylthiazol-2yl)-2, 5-biphenyl tetrazolium bromide (MTT) and neutral red uptake (NRU) assays, and cellular morphology by phase contrast inverted microscopy. The results showed that PSA and PSO significantly reduced cell viability, and altered the cellular morphology of MCF-7 cells in a concentration dependent manner. Concentrations of $50{\mu}g/ml$ and above of PSA and $100{\mu}g/ml$ and above of PSO were found to be cytotoxic in MCF-7 cells. Cell viability at 50, 100, 250, 500 and $1000{\mu}g/ml$ of PSA was recorded as 81%, 57%, 33%, 8% and 5%, respectively, whereas at 100, 250, 500, and $1000{\mu}g/ml$ of PSO values were 90%, 78%, 62%, and 8%, respectively by MTT assay. MCF-7 cells exposed to 250, 500 and $1000{\mu}g/ml$ of PSA and PSO lost their typical morphology and appeared smaller in size. The data revealed that the treatment with PSA and PSO of Petroselinum sativum induced cell death in MCF-7 cells.

Objectives: Insulin resistance (IR) is major cause of type 2 diabetes (T2D), and adipokines (e.g., adiponectin, leptin, and resistin) play an important role in insulin sensitivity. Medicinal plants are frequently used for T2D treatment. This study investigates the effect of Artemisia annua L. (AA) extracts on adipokines in mice with high-fat-diet (HFD)/streptozotocin (STZ)-induced T2D. Methods: We divided 60 mice into 12 groups (n = 5 per group): control, untreated T2D, treated T2D, and 9 other groups. T2D was induced in all groups, except controls, by 8 weeks of HFD and STZ injection. The treated T2D group was administered 250 mg/kg of metformin (MTF), while the nine other groups were treated with 100, 200, and 400 mg/kg of hot-water extract (HWE), cold-water extract (CWE), and alcoholic extract (ALE) of AA (daily oral gavage) along with 250 mg/kg of MTF for 4 weeks. The intraperitoneal glucose tolerance test (IPGTT) was performed, and the homeostasis model assessment of adiponectin (HOMA-AD) index and blood glucose and serum insulin, leptin, adiponectin, and resistin levels were measured. Results: Similar to MTF, all three types of AA extracts (HWEs, CWEs, and ALEs) significantly (p < 0.0001) decreased the area under the curve (AUC) of glucose during the IPGTT, the HOMA-AD index, blood glucose levels, and serum insulin, leptin, and resistin levels and increased serum adiponectin levels in the MTF group compared to the T2D group (p < 0.0001). The HWEs affected adipokine release, while the CWEs and ALEs decreased leptin and resistin production. Conclusion: Water and alcoholic AA extracts have an antihyperglycemic and antihyperinsulinemic effect on HFD/STZ diabetic mice. In addition, they decrease IR by reducing leptin and resistin production and increasing adiponectin secretion from adipocytes.

Objectives : Alcohol-induced liver disease advances as to reactive oxygen species (ROS) and cellular lipid peroxidation increase. We examined the hepatoprotective effects of Zingiber officinale Roscoe rhizome extract (ZR), Pueraria lobata Ohwi flower extracts (PF), and a newly developed herbal juice (HJ), which was a combination of ZR and PF extracts, against ethanol-induced hepatotoxicity. Methods: The study utilized the human hepatoma cell line HepG2 cells to validate the hepatoprotective effect of HJ (50~200 ㎍/mL) against ethanol (EtOH, 700 mM)-induced liver damage. Results: HJ effectively reduced the protein expression of sterol regulatory element-binding transcription factor 1, adiponectin, and AMP-activated protein kinase in EtOH-induced HepG2 cells. The levels of ROS, total cholesterol, and triglycerides, which are the result of various synthesis and lipogenesis processes induced by EtOH in the liver, were reduced by HJ. Furthermore, the activities of alcohol dehydrogenase and aldehyde dehydrogenase, enzymes linked to alcohol degradation, were more effectively downregulated by HJ treatment compared to treatment with ZR and PF alone, all without causing cytotoxic effects. Conclusions: HJ protects the liver by inhibiting EtOH-induced lipogenesis, lowering ROS generation, and improving alcohol degradation, which is more effective than ZR and PF alone. Further, in vivo experiments can offer additional evidence regarding the effectiveness, safety, and underlying mechanism of action of HJ.

Cirsium japonicum (CJ) leaf (L) alcoholic extracts were investigated for analysis their active components (flavonoids and flavanolignans; silymarins) and inhibitory effect on transforming growth factor (TGF)-${\beta}$ induced hepatic stellate cells (HSCs, LX-2 cells) activation. The CJ root (R) extracts were also analyzed and compared with leaf extracts. Total flavonoid and polyphenol contents of the leaf extracts showed higher than those of the root extracts. The content of each flavonoid compound, which was analyzed by HPLC, in CJ-L extracts was also higher than in CJ-R extracts. The results of flavanolignans content in CJ-L and CJ-R extracts were consistent in flavonoid and polyphenol. We studied inhibitory effect of two extracts against TGF-${\beta}1$ induced HSCs activation. The CJ-L extracts significantly suppressed overexpression of profibrogenic factor, ${\alpha}$-smooth muscle actin and collagen-${\alpha}1$(I). The CJ-R extract also showed inhibitory effect on TGF-${\beta}1$ induced HSCs activation, but the efficacy was lower than in CJ-L extract. These results suggest that CJ-L may contribute to the fibrotic liver treatment.
