Abstract

Background: Spirulina is a cyanobacteria species containing various bioactive compounds. Spirulina is a known source of nutrients in some traditional diets. Different activities have been reported for various extracts of S. platensis.

Objectives: In this study, the polysaccharide content of culture media and biomass extract of one species of Spirulina was partially purified, and its analgesic and anti-inflammatory effects were evaluated.

Methods: Spirulina platensis PCST5 was cultured in a sterile Zarouk medium at 27°C and 16/8h of light/ dark exposure cycle for 25 days. Then, the polysaccharide content of biomass and cell-free culture medium samples (BPSs and CFPSs, respectively) was partially purified. The analgesic and anti-inflammatory effects were evaluated using animal models.

Results: 16S rRNA gene analysis confirmed that the organism was genetically similar to Spirulina platensis. The CFPSs (30 and 100 mg/kg) and BPSs (30 mg/kg) significantly reduced pain-related behaviors in rats. Similarly, all samples could significantly reduce carrageenan-induced paw inflammation volume compared with the control group. Our results suggest Spirulina's polysaccharide fractions (CFPSs and BPSs) had significant analgesic and anti-inflammatory effects.

Conclusions: Since Spirulina is a readily available source of bioactive compounds, finding such potent anti-inflammatory and anti-nociceptive compounds can provide promising leads for novel drug development.

部分纯化的无细胞培养基多糖馏分和 PCST5 螺旋藻生物质的镇痛和抗炎作用。

背景：螺旋藻是一种蓝藻，含有多种生物活性化合物。螺旋藻是一些传统饮食中已知的营养来源。据报道，螺旋藻的各种提取物具有不同的活性：本研究部分纯化了一种螺旋藻的培养基和生物质提取物中的多糖含量，并评估了其镇痛和抗炎作用：方法：在无菌 Zarouk 培养基中培养 Platensis PCST5 螺旋藻，培养温度为 27°C，光照/黑暗周期为 16/8 小时，为期 25 天。然后，对生物质和无细胞培养基样品（分别为 BPSs 和 CFPSs）中的多糖含量进行了部分纯化。利用动物模型对其镇痛和抗炎作用进行了评估：结果：16S rRNA 基因分析证实，该生物在遗传学上与螺旋藻相似。CFPSs（30 毫克/千克和 100 毫克/千克）和 BPSs（30 毫克/千克）能显著减少大鼠与疼痛有关的行为。同样，与对照组相比，所有样品都能明显减少角叉菜胶诱发的爪炎症量。我们的研究结果表明，螺旋藻的多糖组分（CFPSs 和 BPSs）具有明显的镇痛和抗炎作用：结论：由于螺旋藻是生物活性化合物的现成来源，找到这种强效抗炎和抗痛觉化合物可为新型药物开发提供有希望的线索。
