Antitoxic Effects

Far from producing deleterious effects, Spirulina has instead showed itself to have antitoxic effects in tests conducted on cells, laboratory animals, and human beings. These properties have been expressed as a protective effect against toxic damage, such as cardiotoxicity, hepatotoxicity, nephrotoxicity, neurotoxicity, eye toxicity, testis toxicity, ovary toxicity, and other effects. Table 2.5 shows some antitoxic properties reported for Spirulina and phycocy-anin against deleterious effects...

Environmental Aspects Of Spirulina Production

There are some environmental advantages of growing Spirulina that are worth mentioning. These features of Spirulina become especially important if developments in technology bring cost of production to make it a protein source competitive enough with the current cheap sources of protein like soya beans. Spirulina production is not associated with some of the environmental degradations like soil erosion, water contamination, and deforestation that are so commonly encountered in conventional crop...

Heavy Metal Contamination

As in other agricultural products, lead, mercury, cadmium, and arsenic are potential contaminants in algal products since they are components of industrial pollution and occur in trace amounts in certain agricultural fertilizers. It is known that certain microalgae are effective accumulators of heavy metals.37 The production of high-quality Spirulina therefore requires the use of high-grade nutrients and a meticulous and routine analysis of heavy metals in the culture medium and the product....

Immune Activation By Spirulina

There have been a number of reports relating to the functions of Spirulina in rodents. Zhang et al.16 reported that the hot water extract of Spirulina showed significant hydroxy radical scavenging activity in mice. In another study, the methanolic extract of Spirulina showed weak antioxidant activity in rats.17 Several papers suggested that the relevant substance is phycocyanin in Spirulina.17,18 Using an experimental squamous cell cancer model of hamsters, administration of Spirulina extract...

Info

TLRs are essential in the first stages of detecting infection and triggering host defenses. TLR2 is generally associated with identifying Gram-positive bacteria and Mycobacteria and its function is enhanced by CD14. CD14 is a membrane-associated glycosylphosphatidylinositol-linked protein expressed at the surface of cells. This pattern recognition receptor is especially associated with macrophages. CD14 acts by assisting in the transfer of bacterial ligands from...

Introduction

Spirulina (Arthrospira), a filamentous, multicellular microalga, is a ubiquitous organism that was used as food in Mexico 400 years ago during the Aztec civilization. It is still being used as food by the Kanembu tribe in the Republic of Chad where it is sold as dried bread called dihe.1 Although it was first isolated by Turpin in 1827 from the freshwater stream, species of Spirulina (Spirulina platensis, Spirulina maxima, Spirulina fusiformis) have been found in variety of environments soil,...

Life Cycle Of Spirulina

The life cycle of Spirulina (Figure 5.2) in laboratory culture is rather simple. A mature trichome is broken into several pieces through the formation of specialized cells, necridia, that undergo lysis, giving rise to biconcave separation disks. The fragmentation of the trichome at the necridia produces gliding, short (two to four cells) chains of cells, and the hormogonia, which move away from the parental filament to give rise to a new trichome. The cells in the hormogonium lose the attached...

Other Toxicities

Lead As in drug toxicities, Spirulina or its bioactive constituent, phycocyanin, has been found to protect from heavy metal poisoning. Again, this protection seems to be mediated mostly by the prevention of oxidative damage through direct antioxidant actions and through induction of endogenous antioxidant enzymes. For example, in rats treated with lead acetate, dietary S.fusiformis (1500 mg kg) reversed the lead-induced inhibition of SOD and catalase activity in liver, lung, heart, and kidney...

Pharmacology And Toxicology Of Spirulina

The pharmacokinetics and pharmacodynamics of Spirulina in humans have not been thoroughly investigated. However, the proteins, lipids, and carbohydrates in Spirulina are digested, absorbed, and metabolized by the humans upon oral consumption. Spirulina can be consumed at a dose of 3-20 g day without manifestation of any adverse effects.91 Studies on the acute, subchronic, and chronic toxicity and mutagenicity of Spirulina have revealed no specific body or organ toxicity or genotoxicity.92,93...

The Role Of Inflammation In Aging

In aging, a series of unchecked inflammatory events can lead to exaggerated proin-flammatory cytokine levels such as, increases in interleukin 1 (IL-1), IL-1 receptor agonists, tumor necrosis factor (TNF), and transforming growth factor- .1> 2 When functioning correctly, cytokines send the appropriate amount of the correct signal to assist in resolving the immune stimulus such as, IL-4, IL-10, and IL-13, which act to suppress inflammation, or IL-1, IL-6, IL-8, IL-11, and IL-12, which act to...

The Role Of Neurogenesis In Aging

Another process impaired in normal aging is neurogenesis within the granule cell layer (GCL) in the hippocampus. Neurogenesis continues to occur throughout the life predominantly in the subgranular zone (SGZ) of the dentate gyrus in the hippo-campal formation and in the subventricular zone (SVZ). Neural stem cells in the SGZ give rise to progenitor cells that migrate in the granule cell layer and differentiate into neuronal or glial phenotype. Progenitors in the SVZ migrate into the olfactory...

Therapeutic Uses Of Spirulina

Spirulina and its active constituents have specific therapeutic uses beyond general nutritional values. In vitro and in vivo studies have shown that either Spirulina or its active constituent, C-phycocyanin is promising in chemoprevention and cancer protection,98 neuroprotection,99 antiviral action,100 cardiovascular protection,87 immunomodulation,101 hepatoprotection,102 anti-inflammatory action,103 antioxidant action,104 and protection against chemical- and drug-induced toxicities.87,105-107

What Is Spirulina

In its commercial use, the common name, Spirulina, refers to the dried biomass of the cyanobacterium, Arthrospira platensis, and is a whole product of biological origin. The source strain, cultivated by producers in the United States was obtained from the University of Texas at Austin Algae Culture Collection (UTEX). This strain, designated UTEX 1926, was originally isolated from an alkaline salt flat near Del Mar, California, by R. Lewin in 1969. In its taxonomic use, Spirulina is a name used...

Worldwide Production Of Spirulina And Its Current

Arthrospira (Spirulina) is currently grown commercially in several countries. The major producers of Spirulina are the DIC group of companies, Earthrise Nutritionals in California, USA Hainan DIC Marketing in Hainan Island, China and Siam Algae Company in Bangkok, Thailand. Together these facilities produce about 1000 metric tons of Spirulina annually. The other major producer is Cyanotech Corporation of Hawaii with an annual production of 300 tons of Spirulina. There are also many producers...

Spirulina Production Nature To Nurture

Most of the information that is used to grow Spirulina in outdoor culture is derived from observations made on natural blooms of these algae in natural lakes. Of special significance is their adaptation to highly alkaline (up to 400 meq l) and very high pH (up to 11) of tropical and subtropical regions of the world. This harsh chemical environment essentially prohibits the growth of other algae. It is therefore not uncommon to find almost unialgal populations of Arthrospira in these lakes. The...

Spirulina Antiviral Studies In Vitro

The first report studying the antiviral properties from the blue-green alga Spirulina was published by Hayashi et al. in 1993. In vitro, they demonstrated that a hot water soluble extract prepared from S. platensis inhibited the replication of herpes simplex virus type 1 (HSV-1) in HeLa cells, in a dose-dependent concentration, from 0.08 to 50 mg mL. The extract did not have a virucidal effect, and the viral inhibition was due to an interference with the penetration event.11 After this report,...

Food and Dietary Supplement GMPs

Spirulina is regulated as food and as a dietary supplement. The latter is a subset of food and falls under FDA's regulation. As discussed earlier, Spirulina is produced under FDA GMPs for food. The FDA has recently released a separate regulation for dietary supplement GMP. Nevertheless, some companies have already attained dietary supplement GMP certification through the industry's (Natural Products Association) certification program. The two facilities in the United States are subject to...

Antiinflammatory Activity Of Spirulina

Cyclooxygenase-2 (COX-2) has an important role in catalyzing the conversion of arachidonic acid to prostaglandins and other eicosanoids.37 The overexpression of COX-2 is associated with high levels of prostaglandin E2 (PGE2) that are observed in various malignancies of the colon, breast, lung, prostrate, skin, cervix, pancreas, and bladder.38 Excess prostaglandin levels cause inflammation, influence cell proliferation, and the mediation of immune suppression.39,40 Many investigations have...

Dietary Supplement Health and Education Act DSHEA and Spirulina

Spirulina is sold in health food stores and similar outlets as a dietary supplement. There appears to be a lack of understanding about their regulatory status. Until 1994 dietary supplements were regulated as foods by FDA. However, with passage of the Dietary Supplement Health and Education Act of 1994 (DSHEA), Congress amended the food regulations to include several provisions that apply only to dietary supplements and dietary ingredients of dietary supplements. As a result of these...
