Theantinociceptive actions of the extract is largely regulated via targeting the nitrergic pathway, while the opioidergic pathway is partly involved.Further, the extract shows antiinflammatory effect due to the significant inhibitions on the time dependent edema progression and the cytokine(tumor necrosis factor-alfa and interleukin-1beta) productions.Conclusion: V. exuberans could be stated as a new source with a high beneficial potential in alleviating pain and inflammation.

🎯
Objective & Hypothesis:Objectives: Safe and effective drugs are still lacking for many pain therapies.
📊
Key Findings & Data:In this study, among Verbascum species, the antinociceptive effect of Verbascum exuberans Hub.-Mor.,and its contributions to nitrergic, serotonergic, or opioidergic pathways as well as its antiinflammatory acitivity were investigated.Materials and Methods: Tail clip, tail flick, and hot plate tests were used to determine the central (spinal and supraspinal) antinociceptive effect,while an acetic acid-induced writhing test was used to measure the peripheral antinociceptive effect of the extract (250 and 500 mg/kg).

Abstract

Objectives: Safe and effective drugs are still lacking for many pain therapies. In recent years, growing interest has been devoted thus on herbaldrugs as an option to identify new pain killers. Based on this, extensive researches are carried out on Verbascum L. genus due to its therapeuticpotency on pain and inflammation therapy. In this study, among Verbascum species, the antinociceptive effect of Verbascum exuberans Hub.-Mor.,and its contributions to nitrergic, serotonergic, or opioidergic pathways as well as its antiinflammatory acitivity were investigated.Materials and Methods: Tail clip, tail flick, and hot plate tests were used to determine the central (spinal and supraspinal) antinociceptive effect,while an acetic acid-induced writhing test was used to measure the peripheral antinociceptive effect of the extract (250 and 500 mg/kg). Theextract (250 mg/kg) was then combined with nω-nitro-L-arginine methyl ester, cyproheptadine, and naloxone to evaluate its involvement in nitrergic,serotonergic, or opioidergic pathways, respectively. Carrageenan-induced hind paw edema model was used to determine the antiinflammatoryeffect of the extract (250 mg/kg).Results: The extract shows central spinal but not central supraspinal antinociceptive effect, and presents peripheral antinociceptive effect. Theantinociceptive actions of the extract is largely regulated via targeting the nitrergic pathway, while the opioidergic pathway is partly involved.Further, the extract shows antiinflammatory effect due to the significant inhibitions on the time dependent edema progression and the cytokine(tumor necrosis factor-alfa and interleukin-1beta) productions.Conclusion: V. exuberans could be stated as a new source with a high beneficial potential in alleviating pain and inflammation.

Özet

Amaç: Birçok ağrı tedavisi için güvenli ve etkili ilaçların arayışı hala devam etmektedir. Nitekim, son yıllarda, yeni ağrı kesicilerin keşfine bir seçenek olarak bitkisel ilaçlara ilginin arttığı görülmektedir. Bu bilgiye dayanarak, ağrı ve enflamasyon tedavisinde, tedavi edici potansiyeli nedeniyle Verbascum L. cinsine yönelik kapsamlı araştırmalar yürütülmektedir. Bu çalışmada, Verbascum türleri arasından, Verbascum exuberans Hub.-Mor.’ın antinosiseptif etkinliğini, bu etkide nitrerjik, serotonerjik ve opioiderjik yolaklar üzerindeki rolünü ve antiinflamatuvar aktivitesini araştırılmıştır. Gereç ve Yöntemler: Ekstrenin (250 ve 500 mg/kg) santral (spinal ve supraspinal) antinosiseptif aktivitesi tail clip, tail flick ve hot plate testleri ile, periferal antinosiseptif etkisi ise asetik asit ile oluşturulmuş kıvranma testi ile ölçülmüştür. Daha sonra, ekstre (250 mg/kg) nω-nitro-L-arginin metil ester, siproheptadin ve nalokson ile kombine edilerek, sırasıyla, ekstrenin nitrerjik, serotonerjik ve opioiderjik yolaklardaki rolü belirlenmiştir. Karragenan ile oluşturulmuş arka ayak pençe ödem modeli ise ekstrenin (250 mg/kg) antiinflamatuvar aktivitesinin belirlenmesinde kullanılmıştır. Bulgular: Ekstrenin santral spinal düzeyde etkili olduğu; ancak santral supraspinal düzeyde etkili olmadığı ve periferal antinosiseptif etkili olduğu görülmüştür. Ekstrenin antinosiseptif etkinliği büyük ölçüde nitrerjik yolağın üzerinden düzenlenirken, opioiderjik yolağın ise kısmen aracılık ettiği belirlenmiştir. Ayrıca, ekstrenin, zamana bağımlı ödem ilerlemesini ve sitokin (tümör nekroz faktörü alfa ve interlökin 1beta) birikimlerini önemli ölçüde engellemesi nedeni ile antiinflamatuvar etkili olduğu bulunmuştur. Sonuç: V. exuberans’ın ağrı ve enflamasyonun giderilmesinde yüksek yararlı potansiyeli ile yeni bir kaynak olduğu ifade edilebilir.
