BACKGROUND Leishmaniasis is a emergent disease characterized by different clinical manifestations in both humans and dogs. Predominant clinical features of cutaneous leishmaniasis are ulcerative painless skin lesions. Several data reported that pain is associated with human and dog leishmaniasis, out with areas of painless ulcerative lesions per se. Actually, current medications used for leishmaniasis management are characterized by several side effects and, in addition, some cases of the disease are refractory to the treatment. On this background it is mandatory the identification of new and safe candidates for designing less toxic and low-cost remedies. Therefore, the search for new leishmanicidal compounds is indispensable. METHODS In the present paper we investigated the effect of orally N-acetyl-L-cysteine (NAC) supplementation at dose of 200 mg/Kg for 10 weeks, in subcutaneous Leishmania (L). amazonensis infected BALB/c mice. And evaluating the effect of NAC on inflammatory response such as TNF-α, IL-6, IL-1β levels, and on thermal and mechanical hyperalgesia. RESULTS In the present paper we showed how NAC supplementation affected parameters of oxidative stress (GSH, MDA, SOD), inflammation such as cytokines levels (IL-1β, IL-6, TNFα) and mast cell activation and consequently on induced pain, during leishmaniosis in BALB\c mice. CONCLUSIONS The findings of our study provided the scientific data demonstrating that L. amazonensis infection induces inflammation and pain in BALB/c mice that are reversed by administration of NAC.

N-乙酰基-L-半胱氨酸减少了BALB / c小鼠中亚马逊利什曼原虫引起的炎症。

背景技术利什曼病是一种以人和狗的不同临床表现为特征的新兴疾病。皮肤利什曼病的主要临床特征是溃疡性无痛皮肤病变。几项数据报道,疼痛与人和狗利什曼病有关,而无痛性溃疡病灶本身就存在。实际上,目前用于利什曼病治疗的药物具有多种副作用,此外,该病的某些情况对该治疗不利。在这种背景下,必须确定新的和安全的候选药物,以设计毒性较小且成本较低的药物。因此,寻找新的杀菌剂化合物是必不可少的。方法在本文中,我们研究了以200 mg / Kg的剂量口服N-乙酰-L-半胱氨酸(NAC)补充皮下利什曼原虫(L)的效果,持续10周。亚马逊感染的BALB / c小鼠。并评估NAC对炎症反应(如TNF-α,IL-6,IL-1β水平)以及热和机械性痛觉过敏的影响。结果在本文中,我们显示了NAC的添加如何影响氧化应激(GSH,MDA,SOD),炎症(如细胞因子水平(IL-1β,IL-6,TNFα)和肥大细胞活化)的参数,并因此导致诱发疼痛BALB \ c小鼠中的利什曼病。结论我们的研究结果提供了科学数据,证明了亚马孙乳杆菌感染在BALB / c小鼠中诱发炎症和疼痛,并通过NAC逆转。在皮下利什曼原虫(L)中。亚马逊感染的BALB / c小鼠。并评估NAC对炎症反应(如TNF-α,IL-6,IL-1β水平)以及热和机械性痛觉过敏的影响。结果在本文中,我们显示了NAC的添加如何影响氧化应激(GSH,MDA,SOD),炎症(如细胞因子水平(IL-1β,IL-6,TNFα)和肥大细胞活化)的参数,并因此导致诱发疼痛BALB \ c小鼠中的利什曼病。结论我们的研究结果提供了科学数据,证明了亚马孙乳杆菌感染在BALB / c小鼠中诱发炎症和疼痛,并通过NAC逆转。在皮下利什曼原虫(L)中。亚马逊感染的BALB / c小鼠。并评估NAC对炎症反应(如TNF-α,IL-6,IL-1β水平)以及热和机械性痛觉过敏的影响。结果在本文中,我们显示了NAC的添加如何影响氧化应激(GSH,MDA,SOD),炎症(如细胞因子水平(IL-1β,IL-6,TNFα)和肥大细胞活化)的参数,并因此导致诱发疼痛BALB \ c小鼠中的利什曼病。结论我们的研究结果提供了科学数据,证明了亚马孙乳杆菌感染在BALB / c小鼠中诱发炎症和疼痛,并通过NAC逆转。以及热和机械性痛觉过敏。结果在本文中,我们显示了NAC的添加如何影响氧化应激(GSH,MDA,SOD),炎症(如细胞因子水平(IL-1β,IL-6,TNFα)和肥大细胞活化)的参数,并因此导致诱发疼痛BALB \ c小鼠中的利什曼病。结论我们的研究结果提供了科学数据,证明了亚马孙乳杆菌感染在BALB / c小鼠中诱发炎症和疼痛,并通过NAC逆转。以及热和机械性痛觉过敏。结果在本文中,我们显示了NAC的添加如何影响氧化应激(GSH,MDA,SOD),炎症(如细胞因子水平(IL-1β,IL-6,TNFα)和肥大细胞活化)的参数,并因此导致诱发疼痛BALB \ c小鼠中的利什曼病。结论我们的研究结果提供了科学数据,证明了亚马孙乳杆菌感染在BALB / c小鼠中诱发炎症和疼痛,并通过NAC逆转。
