It has been used in traditional medicine as a household remedy for various diseases, including biliary disorders, anorexia, cough, diabetic wounds, hepatic disorders, rheumatism and sinusitis. For the last few decades, extensive work has been done to establish the biological activities and pharmacological actions of turmeric and its extracts. Curcumin (diferuloylmethane), the main yellow bioactive component of turmeric has been shown to have a wide spectrum of biological actions. These include its anti-inflammatory, antioxidant, anticarcinogenic, antimutagenic, anticoagulant, antifertility, antidiabetic, antibacterial, antifungal, antiprotozoal, antiviral,anti-fibrotic, antivenom, antiulcer, hypotensive and hypocholesteremic activities. Its anticancer effect is mainly mediated through induction of apoptosis. Its anti-inflammatory, anticancer and antioxidant roles may be clinically exploited to control rheumatism, carcinogenesis and oxidative stress-related pathogenesis. Clinically, curcumin has already been used to reduce post-operative inflammation. Introduction golden hamsters. The Indian Solid Gold Turmeric 4. Curcumin also increases mucin secretion in rabbits.

  • Effect of Curcumin, Mixture of Curcumin and Piperine and Curcum (Turmeric) on Lipid Profile of Normal and Hyperlipidemic Rats
    The Egyptian Journal of Hospital Medicine Vol., 21: 145 – 161 December 2005 I.S.S.N: 12084 2002–1687 Effect of Curcumin, Mixture of Curcumin and Piperine and Curcum (Turmeric) on Lipid Profile of Normal and Hyperlipidemic Rats GHADA, Z. A. Soliman Lecturer of Biochemistry, Biochemistry Department, National Nutrition Institute, Cairo Abstract Curcumin is a polyphenolic, yellow pigment obtained from rhizomes of Curcuma longa (curcum), used as a spice and food colouring. The extracts have several pharmacological effects. We evaluated the effect of curcum, curcumin, and mixture of curcumin and piperine on plasma lipids in normal and hypercholesterolemic rats. A total of 270 rats, divided into 27 groups, were used. G1, G11: control, G2-G11: normal rats fed control diet supplemented with different levels of curcumin and curcum (G2-G6: 0.1%, 0.25%, 0.5%, 1.0%, 2.0% respectively, G7-G11: 1.67%, 4.167%, 8.34%, 16.67%, and 33.34). G12-G26: at first fed control diet supplemented with 2% cholesterol then G13-17, 21-25 fed a control diet supplemented with different levels of curcumin, and curcum [the same levels as G2-G11; G18-20 fed control diet supplemented with mixture of curcumin (0.1, 0.25, 0.5%) and piperine (20 mg/kg BW)], G12 was sacrificed before addition of studied materials, G26 were fed control diet. Lipid profile, triacylglycerol and phospholipids of plasma and organs as liver and heart were measured. Serum cholesterol (total, LDL-C, VLDL-C), triacylglycerol and phospholipids contents were elevated in cholesterol-fed rats, while HDL-C were decreased.

  • As the Industry Develops, Cannabis and CBD Producers Sail Into the Dangerous Shoals of Product Recalls
    As the Industry Develops, Cannabis And CBD Producers Sail Into the Dangerous Shoals of Product Recalls By: Richard M. Blau, Chairman Cannabis Law Group Now that the federal government has legalized hemp and defined lawful cannabidiol (CBD) produced from hemp, the market for CBD products has moved forward with exponential growth. In 2018, approximately $620 million worth of CBD products were sold in the United States. Popular economic advice platforms such as The Motley Fool report projections from economists and industry experts estimating future growth at approximately $24 billion by 2023. Growing CBD revenue from $620 million in 2018 to $23.7 billion by 2023 delivers a compound annual growth rate (CAGR) of 107%. While such statistics reflect a maturing market, so, too , do the arrival of product recalls. Recently, several CBD companies announced voluntary recalls of their products. Summit Labs’ Kore Organic Watermelon CBD Oil On May 12, 2020, Florida-based Summitt Labs, which produces a wide range of hemp-derived cannabidiol (CBD) products, announced a voluntary nationwide recall of its Kore Organic watermelon tincture after the Florida Department of Agriculture and Consumer Affairs conducted a test on a random sample and found high levels of lead. When ingested, lead can cause various symptoms such as pain, nausea and kidney damage; in prolonged exposure situations, lead poisoning has been shown to contribute to degraded brain functions. Summit Labs conducted its own test through an accredited, independent lab that found the lead levels in an acceptable range under state law. But, because the Florida officials found excess lead levels in the sample they tested, Summitt quickly moved to withdraw the product from retailers, who have been notified by phone and email.

  • Pharmacology and Therapeutic Potential of Sigma1 Receptor Ligands E.J
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PubMed Central 344 Current Neuropharmacology, 2008, 6, 344-366 Pharmacology and Therapeutic Potential of Sigma1 Receptor Ligands E.J. Cobos1,2, J.M. Entrena1, F.R. Nieto1, C.M. Cendán1 and E. Del Pozo1,* 1Department of Pharmacology and Institute of Neuroscience, Faculty of Medicine, and 2Biomedical Research Center, University of Granada, Granada, Spain Abstract: Sigma () receptors, initially described as a subtype of opioid receptors, are now considered unique receptors. Pharmacological studies have distinguished two types of receptors, termed 1 and 2. Of these two subtypes, the 1 re- ceptor has been cloned in humans and rodents, and its amino acid sequence shows no homology with other mammalian proteins. Several psychoactive drugs show high to moderate affinity for 1 receptors, including the antipsychotic haloperi- dol, the antidepressant drugs fluvoxamine and sertraline, and the psychostimulants cocaine and methamphetamine; in ad- dition, the anticonvulsant drug phenytoin allosterically modulates 1 receptors. Certain neurosteroids are known to interact with 1 receptors, and have been proposed to be their endogenous ligands. These receptors are located in the plasma membrane and in subcellular membranes, particularly in the endoplasmic reticulum, where they play a modulatory role in 2+ intracellular Ca signaling. Sigma1 receptors also play a modulatory role in the activity of some ion channels and in sev- eral neurotransmitter systems, mainly in glutamatergic neurotransmission. In accordance with their widespread modula- tory role, 1 receptor ligands have been proposed to be useful in several therapeutic fields such as amnesic and cognitive deficits, depression and anxiety, schizophrenia, analgesia, and against some effects of drugs of abuse (such as cocaine and methamphetamine).
