It has been reported that L. propanoid compounds including eugenol and methyl eugenol were the major constituents of EO. EO suppressed the high serum lipid profile and atherogenic index as well as serum lactate dehydrogenase and creatine kinase MB subunit without significant effect on high serum levels of aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase in rats fed with HC diet. In addition, EO was found to decrease the high levels of thiobarbituric acid reactive substances (TBARS), glutathione peroxidase (GPx) and superoxide dismutase (SOD) without impacting catalase (CAT) in the cardiac cells while in the liver, it decreased higher level of TBARS without significantly effecting GPx, SOD and CAT. Histopathological results confirmed that EO maintained the myocardial cells. It can be concluded that EO extracted from OS leaves offers lipid-lowering and antioxidative effects that guard the heart against hypercholesterolemia. Eugenol that is contained in EO likely contribute to these pharmacological effects. L., antioxidant, liver function, cardiac function Intro Hypercholesterolemia is widely known to become the major risk element for Mouse monoclonal to CD54.CT12 reacts withCD54, the 90 kDa intercellular adhesion molecule-1 (ICAM-1). CD54 is expressed at high levels on activated endothelial cells and at moderate levels on activated T lymphocytes, activated B lymphocytes and monocytes. ATL, and some solid tumor cells, also express CD54 rather strongly. CD54 is inducible on epithelial, fibroblastic and endothelial cells and is enhanced by cytokines such as TNF, IL-1 and IFN-g. CD54 acts as a receptor for Rhinovirus or RBCs infected with malarial parasite. CD11a/CD18 or CD11b/CD18 bind to CD54, resulting in an immune reaction and subsequent inflammation the development of cardiovascular diseases [1, 2]. The modern lifestyle with high fat diet and less physical activity significantly contribute to hypercholesterolemia and cardiovascular diseases [1, 3]. Oxidative stress induced by reactive oxygen varieties (ROS) also takes on an important part in the etiology of several diseases including atherosclerosis and coronary heart disease [4, 5]. Hypercholesterolemia has been found to induce oxidative stress in various organs such as the liver, heart and kidney [6]. It has been demonstrated that majority of the vegetation with antioxidant products possess a potential part in protecting people from several illnesses such as cardiovascular diseases [5, 7]. There are several kinds of medicinal vegetation with hypolipidemic and antioxidative activities. One of those vegetation, L. (OS), popular like a vegetable, has shown its potential to be restorative in averting several diseases in various Asian countries including India and Thailand. OS is a small herb, native to tropical and subtropical areas. It is definitely known as Tulsi or Holy Basil in English and India. It has been demonstrated that 2% of dried OS leaf powder supplemented in the diet can lower serum lipid profile and partially protect the liver in diabetic rats [8]. It has also been shown that OS leaf components can guard the liver from weighty metals [9] and prevent isoproterenal-induced myocardial necrosis in rats [10]. Even though OS leaves have hypolidemic and organ protecting effects against numerous stress conditions, yet you will find no research studies providing evidences for its anti-hyperlipidemic and antioxidative effects to protect the primary risk organs against hypercholesterolemia. Moreover, the chemical constituents in OS leaves Plinabulin contributing to these actions have not yet been identified. It is known that OS leaves are riched in essential oils (EO), and the primary risk organs of hypercholesterolemia are the liver and heart. Therefore, the present study was carried out to investigate Plinabulin anti-hyperlipidemic and antioxidative actions of Plinabulin EO extracted from OS leaves to protect the liver and heart in rats fed with high cholesterol diet. The chemical composition of EO was also recognized. Materials and Methods Extraction of essential oils from Ocimum sanctum L. leaves OS fresh leaves were from the Institute of Thai Traditional Medicine, the Ministry of General public Health of Thailand. New leaves of OS were washed in tap water and then slice into small items. The EO from OS leaves was extracted from the hydrodistillation method as described from the Association of Standard Analytical Chemists (method 962.17, AOAC, 1990). After the extraction process, the percent yield of EO was 1.82?ml/100?g of fresh OS leaves. The EO was collected and stored at 4C before analyzing its chemical constituents by Gas Chromatography-Mass Spectrometry (GC-MS). Recognition of volatile constituents using GC-MS The EO was diluted to 1 1:100 in methanol before becoming injected into the GC-MS system. The Varian Saturn III instrument was utilized for Gas Chromatography-Mass Spectrometry analysis. The column was.
