Allergic rhinitis, a frequently occurring immunological disorder affecting men, women and children worldwide, is a state of hypersensitivity that occurs when the body overreacts to a substance such as pollen, mold, mites or dust. Allergic rhinitis exerts inflammatory response and irritation of the nasal mucosal membranes leading to sneezing; stuffy/runny nose; nasal congestion; and itchy, watery and swollen eyes.

The present investigation was an attempt to evaluate the anti-inflammatory effect of a polyherbal preparation (Sudarshanam Oil) on hematological parameters in Wistar rats. This polyherbal formula contains main ingredients of Tinaspora Cordifolia, Curcuma longa, Terminalia chebula, Emblica officinalis, Andrographis paniculata and Terminalia belerica. The active phytochemicals such as tannins, glycosides, flavonoids and triterpenoids are extracted from these herbal plants. And extract was prepared in corn oil.

CONTEXT: Arthritis is inflammation of one or more joints. Terminalia chebula Retz. (Combretaceae) fruit is mentioned in Ayurveda as useful in treating arthritic disorders. OBJECTIVE: This work was undertaken to evaluate the anti-inflammatory, antioxidant, anti-lipid peroxidative and membrane-stabilizing effects of hydroalcoholic extract of Terminalia chebula fruits and also to establish a possible association between them. MATERIALS AND METHODS: In vivo anti-inflammatory activity of T. chebula fruit extract at different doses ranged from 50 to 500?mg/kg, p.o.

Despite the impact of red blood cell (RBC) Life-spans in some disease areas such as diabetes or anemia of chronic kidney disease, there is no consensus on how to quantitatively best describe the process. Several models have been proposed to explain the elimination process of RBCs: random destruction process, homogeneous life-span model, or a series of 4-transit compartment model. The aim of this work was to explore the different models that have been proposed in literature, and modifications to those.

BACKGROUND: Patients with thalassemia major are largely transfusion dependent and are thus exposed to a variety of risks such as transmission of infectious diseases, iron overload and alloimmunization. This study was performed to determine the prevalence of human immune deficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and red cell antibodies among multiple-transfused thalassemic patients in and around the national capital region.

Restriction of energy intake (ER), without malnutrition of essential nutrients, has repeatedly been demonstrated to increase longevity in rodents. In the antioxidant theory of aging the lack of balance between the generation of free radicals and free radical scavenging was thought to be a main causal agent, in the aging process. From this point of view the antiaging effect induced by ER might be due to the lower rate of free-radical production and related damage induced by a lower metabolic rate. The antiaging effects of ER might also occur in humans.

BACKGROUND: Aging is a complex multifactorial process characterized by accumulation of deleterious changes in cells and tissues, progressive deterioration of structural integrity and physiological function across multiple organ systems, and increased risk of death. METHODS: We conducted a review of the scientific literature on the relationship of advanced glycation end products (AGEs) with aging. AGEs are a heterogeneous group of bioactive molecules that are formed by the nonenzymatic glycation of proteins, lipids, and nucleic acids.

BACKGROUND: There are racial health disparities in many conditions for which oxidative stress is hypothesized to be a precursor. These include cardiovascular disease, diabetes, and premature aging. Small clinical studies suggest that psychological stress may increase oxidative stress. However, confirmation of this association in epidemiological studies has been limited by homogenous populations and unmeasured potential confounders.

During human development, the switch from foetal gamma- to adult beta-globin on chromosome 11p is not complete resulting in the residual gamma-globin expression in a modest subpopulation of erythrocytes termed "F-cells". Genetic determinants that are responsible for higher level of Hb F include various mutations within the beta-globin gene cluster as well as singular nucleotide polymorphisms in other loci associated with Hb F quantitative trait, and also epigenetic mechanisms. All these molecular conditions may drive to hereditary persistence of foetal haemoglobin (HPFH).

The human hypothalamus produces an endogenous membrane Na+-K+ ATPase inhibitor, digoxin, which can regulate neuronal transmission. The digoxin status and neurotransmitter patterns were studied in individuals with a predilection to fall in love. It was also studied in individuals with differing hemispheric dominance to find out the role of cerebral dominance in this respect.
