In this article I review the association between exposure to carrageenan and the occurrence of colonic ulcerations and gastrointestinal neoplasms in animal models. Although the International Agency for Research on Cancer in 1982 identified sufficient evidence for the carcinogenicity of degraded carrageenan in animals to regard it as posing a carcinogenic risk to humans, carrageenan is still use...

the present study was designed to explore the anti-inflammatory effect of fluvoxamine, as a selective serotonin reuptake inhibitor (ssri) anti-depressant, on carrageenan-induced paw edema in more details. at first, fluvoxamine was administered intra-peritoneally (2.5, 12.5, 25 and 50 mg kg-1) 30 min before the subplantar injection of carrageenan. fluvoxamine was also injected intra-peritoneally...

objectives: aim of the present work was to investigate the anti-inflammatory, analgesic and antiulcer effects of red seaweed porphyra vietnamensis (p. vietnamenis). materials and methods: aqueous (por) and alcoholic (pe) fractions were successfully isolated from p. vietnamenis. further biological investigations were performed using a classic test of paw edema induced by carrageenan, writhing in...

In the present study we used IL-6 knockout mice (IL-6KO) to evaluate the role of IL-6 in the inflammatory response caused by injection of carrageenan into the pleural space. Compared with carrageenan-treated IL-6 wild-type (IL-6WT) mice, carrageenan-treated IL-6KO mice exhibited a reduced degree of pleural exudation and polymorphonuclear cell migration. Lung myeloperoxidase activity and lipid p...

Background: Opiates affect blood factors as well as pain and inflammation in a gender-dependent manner. The aim of the present study was to evaluate the effects of morphine on serum glucose, cholesterol, triglycerides, and urea in gonadectomized and inflammation conditions. Methods: Animals were divided as follows: control group, carrageenan and chronic morphine recipients, acute morphine recip...

Abstract The quantity and quality of carrageenan produced is influenced by the method extraction solvent. Characterization products necessary to get certain standards so product acceptable consumers both locally internationally. purpose this research was determine solvents that can produce from Kappaphycus alvarezii with best characteristics compare results international in order obtain a stand...

Abstract Carrageenan is used widely in food products especially for gelling, thickening, emulsifying agents, and to stabilize the properties which extracted from red purple seaweeds that contain mixture of polysaccharides. Based on sulfate content, carrageenan divided as kappa-carrageenan, iota-carrageenan, lambda carrageenan. Even though it industry, there controversy about health effects usin...

Carrageenan has been widely used as food additive for decades and therefore, an extended oral data set is available in the public domain. Less data are available for other routes of administration, especially intranasal administration. The current publication describes the non-clinical safety and toxicity of native (non-degraded) iota-carrageenan when applied intranasally or via inhalation. Int...

AIMS Major aims were to determine whether exposure to the commonly used food additive carrageenan could induce fasting hyperglycemia and could increase the effects of a high fat diet on glucose intolerance and dyslipidemia. METHODS C57BL/6J mice were exposed to either carrageenan, high fat diet, or the combination of high fat diet and carrageenan, or untreated, for one year. Effects on fastin...

Background. The dietary usage of carrageenan as common food additive has increased observably over the last 50 years. But there is substantial controversy about its safety. Methods. We investigated whether the κ-carrageenan could enhance lipopolysaccharide-induced IL-8 expression by studying its actions on the TLR4-NF-κB pathway. The aggravating effect of κ-carrageenan on Citrobacter freundii D...
