TL;DR: The present results indicate that resveratrol possesses a strong antifibrogenic effect at least in the CCl4 model of cirrhosis and the action mechanism is probably associated with its ability to reduce NF‐κB activation and TGF‐β content.
Abstract: Resveratrol is a nonflavonoid polyphenol with antioxidant, anticancer and antiinflammatory properties. Moreover, it has been reported that this compound inhibits NF-kappaB, which regulates the transcription of several genes including cytokines such as the profibrogenic TGF-beta. The aim of this work was to evaluate the pharmacological effects of resveratrol on CCl(4)-induced cirrhosis in the rat. Four groups were formed: the control group that received the vehicles only; the CCl(4) group that received the toxin (0.4 g kg(-1), i.p., three times a week, for 8 weeks); the CCl(4) plus resveratrol (10 mg kg(-1), daily) group; and the resveratrol alone group. Alanine aminotransferase, alkaline phosphatase and bilirubins were increased by CCl(4), but resveratrol afforded some degree of protection. Glycogen was decreased markedly by CCl(4) and resveratrol prevented almost completely this effect. No antioxidant effect of resveratrol was observed. One of the most prominent effects was on fibrosis which increased near 5-fold (hydroxyproline) in the CCl(4) group; resveratrol preserved the content of collagen. These results were corroborated by histopathology. To elucidate the antifibrogenic mechanism of resveratrol, the activation of NF-kappaB and the production of TGF-beta were measured; in both cases CCl(4) increased them and resveratrol abolished them; however, changes in NF-kappaB were modest and did not reach statistical significance, while the increase in TGF-beta was about three fold and resveratrol decreased it under control values. Together, the present results indicate that resveratrol possesses a strong antifibrogenic effect at least in the CCl(4) model of cirrhosis. Moreover, the action mechanism is probably associated with its ability to reduce NF-kappaB activation and TGF-beta content.

TL;DR: It was observed that Cytisus scoparius extract protects liver from oxidative stress induced by CCl(4) in rats and thus helps in evaluation of the traditional claim on this plant.

TL;DR: It is concluded that the plant extract is capable of managing hyperglycemia and complications of diabetes in STZ induced diabetic rats and may be considered as one of the potential sources for the isolation of new oral anti hypoglycemic agent(s).
Abstract: The available drugs for diabetes, Insulin or Oral hypoglycemic agents have one or more side effects. Search for new antidiabetic drugs with minimal or no side effects from medicinal plants is a challenge according to WHO recommendations. In this aspect, the present study was undertaken to evaluate the antihyperglycemic and antihyperlipidemic effects of Piper longum root aqueous extract (PlrAqe) in streptozotocin (STZ) induced diabetic rats. Diabetes was induced in male Wister albino rats by intraperitoneal administration of STZ (50 mg/kg.b.w). Fasting blood glucose (FBG) levels were measured by glucose-oxidase & peroxidase reactive strips. Serum biochemical parameters such as glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglycerides (TG), very low density lipoprotein (VLDL), low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol were estimated. The activities of liver and kidney functional markers were measured. The statistical analysis of results was carried out using Student t-test and one-way analysis (ANOVA) followed by DMRT. During the short term study the aqueous extract at a dosage of 200 mg/kg.b.w was found to possess significant antidiabetic activity after 6 h of the treatment. The administration of aqueous extract at the same dose for 30 days in STZ induced diabetic rats resulted in a significant decrease in FBG levels with the corrections of diabetic dyslipidemia compared to untreated diabetic rats. There was a significant decrease in the activities of liver and renal functional markers in diabetic treated rats compared to untreated diabetic rats indicating the protective role of the aqueous extract against liver and kidney damage and its non-toxic property. From the above results it is concluded that the plant extract is capable of managing hyperglycemia and complications of diabetes in STZ induced diabetic rats. Hence this plant may be considered as one of the potential sources for the isolation of new oral anti hypoglycemic agent(s).
