Objective. Inflammation and pain are involved in the pathophysiology of various clinical conditions. This investigation aims to probe the analgesic and anti-inflammatory activity of Maltoamide F. Methods. The possible toxicity of Maltoamide F was evaluated by an acute toxicity test. To assess the anti-inflammatory and antinociceptive effects of Maltoamide F on rats, the models of carrageenan-caused paw edema, xylene-induced ear edema, arachidonic-acid- (AA-) induced ear edema, formalin-caused plantar edema, and cotton-pellet-induced granuloma were established. Levels of TNF-α, PGE-2, and IL-6 were detected by enzyme-linked immunosorbent assay (ELISA). Results. Maltoamide F was safe at oral doses of 1–10 mg/kg for rats. Maltoamide F (1 mg/kg, 5 mg/kg, and 10 mg/kg) notably reduced carrageenan-induced edema percentage of paws in rats and decreased levels of PGE-2, IL-6, and TNF-α in homogenates of foot tissues. Maltoamide F (1 mg/kg, 5 mg/kg, and 10 mg/kg) reduced levels of PGE-2, IL-6, and TNF-α in foot tissues of formalin-induced rats. Maltoamide F (1 mg/kg, 5 mg/kg, and 10 mg/kg) repressed AA-induced increase of ear thickness in rats and reduced levels of PGE-2, IL-6, and TNF-α in homogenates of ear tissues. Maltoamide F (1 mg/kg, 5 mg/kg, and 10 mg/kg) reduced xylene-induced weight of ear edema in rats and reduced levels of PGE-2, IL-6, and TNF-α in homogenates of ear tissues. Maltoamide F (1 mg/kg, 5 mg/kg, and 10 mg/kg) reduced levels of PGE-2, IL-6, and TNF-α in homogenates of cotton ball granuloma of cotton-pellet-induced rats. Conclusions. Maltoamide F possessed anti-inflammatory and analgesic activity in inflammatory models of rats.

Objective: The aim of the present study was to evaluate anti-inflammatory activity of methanolic extract of Terminalia coriacea. Materials and Methods: A methanolic extract of T. coriacea leaves was studied in albino Wistar rats with carrageenan-induced paw edema, an acute model, and cotton pellet-induced granuloma, a chronic model, at 3 oral test doses (125, 250, and 500 mg/kg). Aspirin 100 mg/kg was used as a positive control. Paw volume and wet and dry weights of cotton pellets were determined. The data were analyzed by one-way ANOVA followed by Dunnett’s multiple comparison test. Results: The test extract at doses of 125 and 250 mg/kg decreased paw volume and wet and dry weights of cotton pellets. The highest test dose (500 mg/kg) displayed a response comparable to that of the standard drug (p < 0.01) on paw volume. The extract produced similar (p < 0.05) decrease in wet weight of the cotton pellet at 125 and 250 mg/kg, whereas the effect of 500 mg/kg of the extract was comparable to that of aspirin 100 mg/kg (p < 0.01). The extract of T. coriacea at 500 mg/kg induced the most significant (p < 0.01) effect on wet weight of granulomatous tissue. Conclusion: The methanolic extract of T. coriacea leaves successfully decreased paw edema as well as dry and wet weights of granulomatous tissue in both acute and chronic inflammatory models thus confirming the anti- edematogenic, antitransudative, and antiproliferative properties of T. coriacea.

Abstract. Belay R, Makonnen E. 2018. Anti-inflammatory activities of ethanol leaves extract and solvent fractions of Zehneria scabra (Cucurbitaceae) in rodents. Biofarmasi J Nat Prod Biochem 18: 42-56. Zehneria scarba (L.f.) Sond is one of the medicinal plants used in folkloric medicine of Ethiopia for years to treat various inflammatory disorders. The present study was aimed to validate the anti-inflammatory activity of crude 70% ethanol leaves extract (70EE) against a sub-acute model and further evaluate the solvent fractions (AF, BF, and CF) in an acute (carrageenan-induced paw edema), sub-acute (formaldehyde induced arthritis) and chronic (cotton pellet induced granuloma) inflammatory models. The 70EE was first prepared by maceration, and the fractions were obtained by sequential partitioning with chloroform and n-butanol from the aqueous suspension of crude 70EE. The test groups, then, received 100, 200 and 400 mg/kg of the crude 70EE or the fractions (AF, BF, and CF) at the same dose levels, whereas positive controls received aspirin (200mg/kg) or dexamethasone (0.5mg/kg) and negative controls received vehicle (2% tween 80 or distilled water, 10 mL/kg). All tested doses of the crude 70EE showed significant inhibition of formaldehyde induced arthritis at the 10th day of treatment, on which the 400mg/kg dose showed the maximum anti-arthritic effect (%A = 60.5; p < 0.001). In the carrageenan-induced paw edema, all the three fractions showed a statistically significant effect, in fact, with different onset and magnitude. In this model, the AF was found to be the most active fraction, and the 400mg/kg dose demonstrated the maximum effect (%A = 76.25; p < 0.001) at 5h post-induction, which is much better than the effect of aspirin at the dose employed. The overall order of efficacy in inhibiting the exudative component of carrageenan-induced paw edema was found to be AF> BF> CF. The AF was also found to be the most active fraction in inhibiting the exudative component of chronic inflammation in the cotton pellet induced granuloma model, where the maximum effect (%A = 43.10, p < 0.001) was exhibited by a dose of 400mg/kg. The AF was also the most active fraction in inhibiting formaldehyde induced arthritis, in which the BF and CF relatively showed a comparable effect throughout day 4-10. On the contrary, in the cotton pellet induced granuloma model, the CF was found to be the most active fraction in inhibiting the proliferative and granulomatous component of chronic inflammation, and the overall order of effectiveness was found to be CF> AF> BF. Besides, 400mg/kg of CF demonstrated the maximum inhibition of granuloma formation (%A = 55.52; P < 0.001). The phytochemical analysis revealed the differential distribution of secondary metabolites into the three fractions, which either singly or in concert appeared to be responsible for the observed effects. The data obtained from the present study collectively indicate that the extract and fractions of leaves of Z.scabra possessed a significant anti-inflammatory activity, upholding the folkloric use of the plant.

Flemingia strobilifera R.Br. (Fabaceae), is a perennial plant traditionally used as an indigenous medicine for its pharmacological characteristics. The goal of our experimentation was to study the chloroform extract of F. strobilifera roots for its anti-inflammatory potential through anti-inflammatory models like carrageenan - elicited rat hind paw edema , cotton pellet - elicited granuloma formation, and carrageenan - elicited leucocyte to justify ethno-medicinal use of the plant. Indomethacin, a reference drug, was used to compare anti-inflammatory potential. The extract, administered respectively with a lower dose of 30 mg and 60 mg per kg body weight as higher dose, three hour post treatment, produced a significant reduction (p < 0.01) in the edema of paw and substantial decrease in implanted cotton pellets dry weight. We conclude that the chloroform extract of roots of F. strobilifera possess osedependent, anti-inflammatory activity.

The topical anti-inflammatory activity of essential oil of Pistacia lentiscus L. was studied using carrageenan induced rat paw edema and cotton pellet induced granuloma. The effect on serum tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in rats inserted with cotton pellet was also investigated. On topical application, the oil exhibited a significant decrease in paw edema. The oil also inhibited cotton pellet-induced granuloma, and reduced serum TNF-α and IL-6. It can be concluded that the essential oil of Pistacia lentiscus reduces leukocyte migration to the damaged tissue and exhibits anti-inflammatory activity.

Background: Pain and inflammation are disabling accompaniments of many medical conditions. So, controlling both pain and inflammation assumes the top priority for the physician. Inflammation is a part of a complex biological response of vascular tissues to harmful stimuli such as pathogens, chemicals or irritants. Therapy of pain and inflammation has always been debatable.Methods: Rats were divided into 8 groups of 6 animals of each. The anti-inflammatory activity was studied with carrageenan induced rat paw edema and cotton pellet induced granuloma models. The analgesic activity was evaluated using Eddy’s hot plate model. The aqueous extract of Rubia cardifolia root and Cassia fistula leaf preparations were compared with Diclofenac in both acute and sub acute inflammatory models and also in pain model.Results: Various test result parameters were statistically analysed at P value <0.5. In Eddy's hot plate model both RC and CF preparations prolonged the response reaction time, while CF preparation showed longer reaction time than that of RC preparation. In carrageenan induced paw edema and cotton pellet induced granuloma models, both RC and CF preparations showed significant decrease in paw edema volume and granuloma dry weight respectively, but less than that of Diclofenac. RC preparation found to have dose dependant in inflammatory models.Conclusions: RC root and CF leaf preparations were compared head to head and they have been found to have significant dose dependant analgesic activity and dose independent acute and sub acute anti inflammatory activities. Though CF leaf preparation appeared to be a good analgesic than RF root preparation, but failed to do so as an anti inflammatory agent in both inflammatory models. But both test preparations were not equivalent to Diclofenac in all three models.

Background: NSAIDS are commonly prescribed drugs in clinical practice. However, their usage is limited by their toxicity profile and research continues for an alternative therapy with higher efficacy and safety. Various plant preparations found to be safe and effective are emerging, but their interactions with synthetic drugs are not much known.Methods: Wistar rats were divided in to four groups of six animals each Rubia cordifolia (RC) root preparation and casissia fistula (CF) leaf preparation were studied with sub anti-inflammatory dose of diclofenac in various analgesic, acute and subacute inflammatory models and test results variables were expressed in mean reaction time, paw edema volume and granuloma weight respectively.Results: Various test results were tabulated, statistically analysed and significance was calculated at P value <0.5. Eddy’s hot plate model did not show any significant change, but carrageenan induced paw edema model and cotton pellet induced granuloma model showed comparable decrease in paw edema volume and granuloma dry weight.Conclusions: Diclofenac, a standard analgesic and anti –inflammatory was not potentiated in pain model but it was potentiated in carrageenan and cotton pellet granuloma models in a variable manner. CF potentiates acute anti-inflammatory action, whereas RC potentiates subacute anti-inflammatory actions of diclofenac.

Purpose: To evaluate the anti-inflammatory activity of Liquidambar formosana  Hance infructescence (Liquidambaris fructus, ELF) in vivo, and clarify its underlying mechanisms. Methods: The in vivo anti-inflammatory activity of ELF was examined by xylene-induced ear swelling test in mice as well as carrageenan-induced paw edema method in rats. The levels of inflammatory cytokines (TNF-α, IL-1β, IL-6 and IL-10) in serum were measured by enzyme-linked immunosorbent assay (ELISA), while the expressions of COX-2, iNOS and NF-κB p65 in paw tissue of rats were evaluated by western blot.Results: After ELF treatment, the levels of TNF-α (p < 0.001), IL-1β (p < 0.001) and IL-6 (p < 0.001) in serum decreased and the levels of anti-inflammatory cytokine IL-10 increased (p < 0.01). In addition, ELF treatment resulted in decrease of COX-2 (p < 0.01), iNOS (p < 0.01) and NF-κB p65 (p < 0.01) expressions in Wistar rats.Conclusion: The results reveal that ELF possesses significant anti-inflammatory effect in vivo. The anti-inflammatory activity is associated with the levels of TNF-α, IL-1β, IL-6 and IL-10 in serum. Furthermore, the suppression of NF-κB p65, iNOS and COX-2 is linked to its anti-inflammatory effect. These results provide a rationale for the use of Liquidambaris fructus in inflammatory disease in traditional medicine.Keywords: Anti-inflammatory activity, Liquidambaris fructus, Cytokines, Ear swelling test, Paw edema

Crotamine, a toxin found in the venom of the South American rattlesnake Crotalus durissus terrificus, has been reported to have antinociceptive effects. We purified recombinant crotamine expressed in Escherichia coli and investigated its antinociceptive and anti-inflammatory effects using the hot-plate test, acetic-acid-induced writhing method, and formalin test in mice. Recombinant crotamine was administered intraperitoneally (0.04–1.2 mg kg−1) or intraplantarly (0.9–7.5 μg 10 μL−1) before the tests. The paw volume was measured with a plethysmometer. To evaluate the antagonistic and anti-inflammatory effects of naloxone, subcutaneous naloxone (4 mg kg−1) or intraplantar naloxone (5 μg 10 μL−1) was administered before recombinant crotamine. For tumor necrosis factor (TNF)-α assays, blood was drawn 3 h after formalin injection and measured using enzyme-linked immunosorbent assay. Intraperitoneal and intraplantar recombinant crotamine had antinociceptive and anti-inflammatory effects, neither of which were affected by pre-treatment with naloxone. The mean serum TNF-α levels were significantly lower in the intraperitoneal recombinant crotamine (0.4 and 1.2 mg kg−1) or intraplantar (2.5 and 7.5 μg 10 μL−1) recombinant crotamine groups than in the saline group and were not affected by naloxone pre-treatment. In conclusion, recombinant crotamine possesses significant antinociceptive and anti-inflammatory effects that do not appear to be related to the opioid receptor. The antinociceptive and anti-inflammatory effects of intraperitoneal or intraplantar recombinant crotamine are related to TNF-α.

Introduction: The present study deals with the effect of Nectaroscordum koelzi fruit extract on acute and chronic inflammation. Methods: Totally, 84 NMRI mice were used in this study. The extract effect on acute inflammation was analyzed by increasing vascular permeability via acetic acid and xylene induced ear edema among mice. The extract was evaluated in terms of effects on chronic inflammation by means of the cotton pellet test among mice. For the assessment of inflammation degree, the mice paw edema volume was measured by the plethysmometric test. Results: The findings showed that the extract was effective on acute inflammation induced by acetic acid in mice. In the xylene ear edema, N. koelzi extract indicated the significant activity in mice. In the cotton pellet method, the methanol extract produced a significant reduction in comparison with the control and dexamethasone. Mice paw edema volume decreased with the extract. Conclusion: In general, the data from the experiments indicated that the methanol extract of N. koelzi has an anti-inflammatory effect on acute and chronic inflammation. However, the exact contributing mechanisms have not been investigated for the pharmacological effects.
