Background: Smilax zeylanica Linn (Smilaceae) is a woody climbing shrub native to Asia's tropical and subtropical highlands. Traditionally, this plant has been widely used to cure a variety of ailments. Smilax zeylanica stem bark was extracted with ethanol to test its antinociceptive and anti-inflammatory properties. Objective: To study the antinociceptive and anti-inflammatory activities of ethanolic stem bark extract of Smilax zeylanica Linn. in Wistar rats. Methods: The antinociceptive activity has been assessed in mice by formalin-induced paw licking, Eddy’s hot-plate, and acetic-acid induced abdominal stretching models. Carrageenan-induced paw oedema in rats has been conducted to explore the anti-inflammatory activity. Tween 80 (10ml/kg, p.o) was given to the control group, test drug group received ethanol extract of Smilax zeylanica (EESZ) orally at doses of 200 and 400 mg/kg, and standard drugs morphine (5 mg/kg, s.c), diclofenac sodium (10 mg/kg, i.p) were injected to the standard drug group. Results: Oral administration of ethanolic extract of Smilax zeylanica (EESZ) at test doses (200 and 400 mg/kg), produced a significant decrease of the paw licking time for 2 phases (neurogenic and inflammatory) in the formalin test, upsurge of the reaction time in Eddy’s hot plate test, and significantly decreased the abdominal stretching in the acetic acid-induced  writhes test. Ethanol extract of Smilax zeylanica significantly decreased the carrageenan-induced paw oedema. Conclusion: The ethanol extract of Smilax zeylanica possesses antinociceptive, anti-inflammatory activity, probably involving central and peripheral pathways

Background: 3,4,5-Trihydroxybenzoic acid, which is also known as gallic acid, is an anti-inflammatory agent who could provide beneficial effects in preventing periodontal inflammation. The present study aimed to evaluate the anti-inflammatory effects of gallic acid on experimental periodontitis in Wistar rats. Alveolar bone loss, osteoclastic activity, osteoblastic activity, and collagenase activity were also determined. Methods: 32 Wistar rats were used in the present study. Study groups were created as following: Healthy control (C,n=8) group; periodontitis (P,n=8) group; periodontitis and 30 mg/kg gallic acid administered group (G30,n=8); periodontitis and 60 mg/kg gallic acid administered group (G60,n=8). Experimental periodontitis was created by placing 4-0 silk sutures around the mandibular right first molar tooth. Morphological changes in alveolar bone were determined by stereomicroscopic evaluation. Mandibles were undergone histological evaluation. Matrix metalloproteinase (MMP)-8, tissue inhibitor of MMPs (TIMP)-1, bone morphogenetic protein (BMP)-2 expressions, tartrate-resistant acid phosphatase (TRAP) positive osteoclast cells, osteoblast, and inflammatory cell counts were determined. Results: Highest alveolar bone loss was observed in the periodontitis group. Both doses of gallic acid decreased alveolar bone loss compared to the P group. TRAP-positive osteoclast cell counts were higher in the P group, and gallic acid successfully lowered these counts. Osteoblast cells also increased in gallic acid administered groups. Inflammation in the P group was also higher than those of C, G30, and G60 groups supporting the role of gallic acid in preventing inflammation. 30 and 60 mg/kg doses of gallic acid decreased MMP-8 levels and increased TIMP-1 levels. BMP levels increased in gallic acid administered groups, similar to several osteoblasts. Conclusion: Present results revealed an anti-inflammatory effect of gallic acid, which was indicated by decreased alveolar bone loss and collagenase activity and increased osteoblastic activity.

The seeds of Ammodaucus leucotrichus Cosson and Durieu have been used in the North African Sahara as a traditional medicine to treat diabetes. The present study investigates the antidiabetic, antihyperglycemic, and anti-inflammatory properties of the defatted hydroethanolic extract of Ammodaucus leucotrichus (DHEAM). The antidiabetic and the antihyperglycemic studies were assessed on alloxan-induced diabetic with orally administered doses of DHEAM (100 and 200 mg/kg). At the same time, its anti-inflammatory propriety was evaluated by measuring edema development in the Wistar rats paw induced with carrageenan. Treatment of diabetic mice with DHEAM for four weeks managed their high fasting blood glucose levels, improved their overall health, and also revealed an excellent antihyperglycemic activity. Following the anti-inflammatory results, DHEAM exhibited a perfect activity. HPLC results revealed the presence of seven molecules (chlorogenic acid, 3-p-coumaroylquinic acid, gallic acid, ferulic acid, myricetin, quercetin, luteolin). This work indicates that the DHEAM has an important antidiabetic, antihyperglycemic, and anti-inflammatory effect that can be well established as a phytomedicine to treat diabetes.

Abstract Background Exposure to arsenic orchestrates a myriad of noxious health effects, including cancer. Different parts of Irvingia gabonensis are used as herbal remedies in traditional medicine. In this study, the comparative effects of the ethanol leaf (ELEIG) and stem bark extracts (ESEIG) of Irvingia gabonensis on sodium arsenite (SA)-induced lipid profile disturbances in Wistar rats were investigated. Methods Fifty five Wistar rats weighing between 100 g and 179 g were distributed into eleven groups (n=5). Group 1 (control) received feed and water ad libitum. Group 2 received SA at a dose of 4.1 mg/kg body weight (kgbw) for 14 days. Groups 3–11 were treated with the extracts with or without SA. Treatment was done by oral intubation for 14 days. Serum concentrations of total cholesterol (TC), triacylglycerol (TAG), high density lipoprotein cholesterol (HDL-c), low density lipoprotein cholesterol (LDL-c), very low density lipoprotein cholesterol (VLDL-c), total lipids (TL) and atherogenic index of plasma (AIP) were used to determine the lipid profile effects of the extracts. Results Exposure to SA caused significant (p ˂ 0.05) increases in all assayed parameters, relative to control. Post-treatment and simultaneous treatment with ELEIG and ESEIG mitigated the effects of SA. In addition, ELEIG alone at various doses produced results comparable with control values. However, ESEIG alone caused significant (p ˂ 0.05) increases in all assayed parameters, relative to control. Conclusion These results show that ELEIG and ESEIG ameliorate SA-induced lipid profile disturbances in Wistar rats. However, long-term administration of ESEIG alone may be discouraged.

Anogeissus pendula Edgew has been reported to be used in gastric disorder even though no attempt has been made to evaluate the same. The present study was designed to evaluate the hydroalcoholic extracts of stem bark and leaves for in vivo acute antiulcer and anti-inflammatory activities. Antiulcer activity was studied by pylorus ligation induced ulcers while anti-inflammatory activities was studied by carrageenan induced paw edema. The extract of stem bark at 200 and 400 mg/kg b. w., significantly (P<0.05) reduced ulcer index whereas extracts of both stem bark and leaves significantly (P<0.001) reduced paw diameter at the fifth hour. The hydroalcholic extract of stem bark of A. pendula possesses more significant antiulcer and anti-inflammatory activity than the hydroalcholic extract of leaves may be due to the presence of higher amount of phenolic compounds.
