Nowadays, Spirulina has been marketed and consumed as a human food and has been approved as a food for human consumption by many governments, health agencies, and associations of almost countries ( Becker and Venkataraman, 1984; Vonshak, 2002; … After the treatment, the striatal dopamine (DA) content was analysed by high performance liquid chromatography, and lipid peroxidation was studied as an index of oxidative stress. The techniques used for the restoration of lakes or to prevent eutrophication are numerous (chemical, biologic, mechanical, etc). Panel III Guidelines. 2005. Arthrospira Platensis Harmful. It is a source of antioxidants, strengthens the immune system and improves the tone and vitality of … Appl Environ Microbiol 1997;64:2206-12. on of the active constituent enriched herbal extract using a green extraction method. One of the most efficient sources of complete plant-based protein is spirulina. Spirulina is a cyanobacterium, or blue-green algae, belonging to the Arthrospira genus. Dried extract was then, stored at 4°C in sterilized sealed plastic con, away from light until use. The company name SPLAT comes from Spirulina platensis – among its first products were cosmetics and dietary supplements containing this blue-green algae. both sexes. Our inoculum is certified and safe, we buy it from laboratories of proven trust and in compliance with the highest quality standards. The ingredient is a powder consisting of whole dry cells of A. platensis. Arthrospira platensis was dried at 50°C and ground to. and allow not only a good degree of expression of the introduced gene but also to maintain itself in a fast-growing culture . The aim of the present study was to evaluate the antioxidant capacity of a Spirulina extract. Ltd. (Songkhla, Thailand). Stomach aches have been reported, as have mild itches and rashes. powder using a grinder and a sieve no. In all cases, their feces were dried and darkly color. In this study, the methanol extract of Arthrospira (Spirulina) platensis was examined for acute and subchronic toxicities. Arthrospira platensis var. So…cultivating spirulina at home and in an artificial environment erases all risk? Bien que communément appelée « spiruline » (« spirulina » en anglais), cette cyanobactérie appartient au genre Arthrospira . Ninety-six male C-57 black mice were pretreated with Spirulina for 14 days (25, 50, 100, 150 or 200 mg/kg, oral), followed by three MPTP administrations (30 mg/kg, intraperitoneal, i.p.). The two most important species of which are Spirulina maxima and Spirulina platensis. The antioxidant activity of a methanolic extract of Spirulina was determined in vitro and in vivo. Short-term (5 d) and prolonged-term (5 d/week, for 10 weeks) feeding, was followed by mating with untreated adult virgin females. hematology and clinical chemistry parameters of treated groups did not significantly differ from those of the controls in 2 Material and Methods 2.1 Algae culture and treatment . c) the FDA, the US government agency that deals with the regulation of food and pharmaceutical products and which directly depends on the Department of Health and Human Services of the United States, after careful checks, granted the spirulina the status of “Generally Recognized As Safe” (GRAS) “, and its beneplacet to commercialization in the United States. The present study aimed to fill this gap and surveyed a group of Polish consumers of microalgal products (n = 150) using an online questionnaire. Thus, building on earlier results of ameliorated neurobehavioral and cognitive abilities in Spirulina supplemented protein deprived rats, the present study incorporates neurochemical and morphometric analysis of glial cells and neurons and revealed that maternal Spirulina consumption partially prevented the PMN associated neuropathological alterations in terms of attenuated oxidative brain damage, reduced reactive gliosis and apoptotic cell population, improved dendritic branch complexity with few damaged neurons and enhanced mushroom shaped spine density. Bark in Mice and Rats, A Subchronic Toxicity Study of Spirulina platensis. It was expected from these results that spirulina may prevent dietary hypercholesterolemia and arteriosclerosis. As of today, spirulina is mainly used as a food supplement for human consumption. First of all it is important to make some clarifications: a) when we talk about spirulina we refer to one of the about 2000 families of cyanobacteria present in nature, which are not only very different from each other, morphologically, biochemically and physiologically, but live, feed, replicate in different places and in different chemical and physical conditions. Tests conducted in 2000 by Gilroy (the researcher most cited by the alarmists), have found the presence of toxins, albeit low, in some supplements based on Spirulina. against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) neurotoxicity, used as a model of Parkinson's disease. Growth and metabolic response of the filamentous cyanobacterium Spirulina platensis to salinity stress of sodium chloride. In summary, the present study highlights that microalgal consumers may benefit from additional warnings of potential side effects and from consulting a qualified health specialist prior to use. The pharmacological and toxicological studies (acute, subchronic, chronic, reproductive, genotoxic) have evaluated Spirulina for possible toxicity and revealed that Spirulina is non-toxic and exert no adverse effects on physiological functions when grown under controlled conditions (Hutadilok-, ... Spirulina platensis is a microalga of the group Cyanobacteria, has been consumed for thousands of years by the Aztecs and nations in Africa as food, and has been designated as a material that is Generally Recognizes As Safe (GRAS) since 1981 by the FDA, no toxicity was found in administration with dosage of 24g / kg body weight for 12 weeks (Hutadilok-Towatana et al. So how can we explain the contrary reports that we find online from time to time? algue-spiruline.fr. It was examined for subchronic toxicities at doses of 6, 12 and 24 mg kg -1 body weight daily for 12 weeks, showing normal white blood cells counts in all treated groups similar to the control. The microalgae Chlorella vulgaris and Arthrospira platensis were evaluated as nutraceuticals. スピルリナ水溶性画分, スピルリナ不溶性画分を基本飼料に20%混入して, Sprague-Dawley系雄ラットを28日間飼育し, 生体に及ぼす影響を比較した。1) 成長, 飼料効率は, 対照と等しく良好であった。2) 血糖値i) 空腹時血糖値は, スピルリナ水溶性画分投与群において低い傾向が認められた。ii) 糖負荷時の血糖値上昇抑制傾向は, スピルリナ不溶性画分投与群でスピルリナ水溶性画分投与群より大であった。3) コレステロール値i) 血清総コレステロール値は, スピルリナ水溶性画分投与群が低い傾向にあった。ii) HDL-コレステロール値は, スピルリナ水溶性画分, スピルリナ不溶性画分投与群に高い傾向がみられた。.
