This greater protection may be due to the phenolic components of grapes buy prednisolone discount pollen allergy medicine in japan, which are particularly abundant since they behave as reactive oxygen species-scav engers and metal-chelators proven 20mg prednisolone allergy forecast york pa. Polyphenolic substances in grapes and other red fruits are usu ally subdivided into two groups: flavonoids and nonflavonoids order prednisolone 20mg on line allergy medicine for children under 3. In many cases order prednisolone 40 mg fast delivery allergy shots long term effects, it is unclear if oxidants trigger the disease, or occur as a result of this and cause the symptoms of the disease as a plausible alternative, a neurodegenerative disease may result from defective axonal transport of mitochondria that perform oxidation reactions. A case in which it fits is particularly well understood in the role of oxidative stress in cardiovascular disease. In diseases that have a high impact on the health sector Diabetes Mellitus is one of the most known. Countries like China, India, United States of America and Mexico are at the top of this pathology [16]. In Mexico, this condition is a major cause of mortality and morbidity are estimated to be ap proximately 10 million individuals with diabetes, of whom 22. The disorder is characterized by the inadequate use of glucose, due to insufficient produc tion, insulin resistance and some without production of the hormone, resulting in unfavora ble a high index of this monosaccharide in the blood. Different factors increase the likelihood of the individual to develop diabetes as are smok ing, sedentary lifestyle, lack of exercise coupled with unbalanced diet causes both over weight and obesity. Obesity increases oxygen consumption and thus the production of free radicals, thus creat ing the phenomenon known as oxidative stress. Alternative medicine Due to the current problem in the health issue we propose the use of herbs as an option to improve the style of living of the people, not only for the adjuvant treatment, but because the use of plants offers great nutritional benefits somehow reducing the incidence of such chronic degenerative diseases. This is not intended to impair the option of preventive diag nosis by the health sector does not provide such benefits, but rather the use of plants known to have medicinal activity coupled with the clinical - pharmacology, could present better re sults, for the treatment of the various degenerative chronic diseases. Given the increasing scientific evidence that the etiology of several chronic degenerative diseases such as diabetes is influenced by factors such as metabolic redox imbalance. Is currently booming studying the formation of metabolites against free radicals that diverse plant species presents. Similarly, Mexico has focused attention on other plants with potential antioxidant properties and for some years and was used in the treatment of diabetes. More recently, we began to evaluate the antioxidant properties of some of these plants through in vitro techniques [20]. Antioxidant effects in Mexican plants The use of traditional medicine is widespread in Mexico and plants are indeed the first source for preparing remedies in this form of alternative medicine. Among the various compounds found in plants, antioxidants are of particular importance because they might serve as leads for the development of novel drugs. The search for natural sources of medicinal products that also have antioxidant and radical scavenging activity is on the rise [23,24]. The latex of Sapium macrocarpum is used against scorpion stings, fever and some skin problems such as warts; its use as an anti-coagulant is also widespread. The latex of Ficus cotinifolia is used in the treatments of urinary infections, vomiting, malaria and against inflammatory pathologies of the spleen. The leaves of Vitex molli are used to treat stomach ache, diges tion disorders, nervous alterations, and also scorpion stings. Piper leucophyllum is employed for reducing fever and its dried leaves are used for cleaning eyes and as spice in cooking. The Mexican and Central America native species of Astianthus viminalis is used for the curing of diabetes and malaria and to reduce hair loss. Swietenia humilis is used as anti parasitic, and it is also utilized for hair care as a shampoo. It is also used with other plants in mixed herbal teas, and used as home remedies. Stemmandenia bella is employed for curing wounds; Rupechtia fusca is used in some stomach disorders; Bursera grandifolia is used as a tooth paste and against diges tive disorders; Ziziphus amole is prepared as infusion and it is applied for washing wounds and to treat gastric ulcers. The fruit and the latex of Jacaratia mexicana are used against ulcers in the mouth and digestive disorders. Pseudobombax ellipticum is used in respiratory disorders such as cough, and also against fever and as an anti microbial. The stems and flowers of Comocladia engleriana are toxic because they produce dermatitis. The flowers and the latex of Plumeria rubra can be used for stopping vaginal blood shed, and toothache, and the la tex of the plant is used against earache. Many species have been recognized to have me dicinal properties and beneficial impact on health, e. Crude extracts of herbs and spices, and other plant materials rich in phenolics are of increasing interest in the food industry because they retard oxidative degradation of lipids and thereby improve the quality and nutritional value of food. Various clases of flavo noid differ in the level of oxidation and saturation of ring C, while individual compounds within a class differ in the substitution pattern of rings A and B. The differences in the struc ture and substitution will influence the phenoxyl radical stability and thereby the antioxi dant properties of the flavonoids. Many spices have been investigated for their antioxidant properties for at least 50 years [29,30]. Antioxidant properties of Moringa oleifera: In this experiment were collected fresh leaves of M. After one week the solvent was decanted and concentrated under reduced pressure using a rotary evaporator. The crude methanol extract was stable in distilled water obtained the following experimental concentrations: 50, 25, 12. Comparison of the antioxidant properties of Azadirachta indica with other species and a commercial product. The protocol is divided into two parts, one of which was evaluated for antioxidant activity from four different extracts from leaves of Azadirachta indica: a) methanol, b) infusion, c) ethyl acetate and d) ethanol. It was found that infusion of Neem showed the highest antioxidant activity (80% inhibition) than the other extracts even from the first minute after initiating the reaction. This would correspond to the ethnomedical use that people from rural zones done with this tree, and then take it as a tea before the first food of the day. In this regard, our laboratory is conducting a more rigorous characteri zation of secondary metabolites found in these plants by using spectroscopic techniques (e. From this concentration the experiment was performed with a duplicated calibration curve at different concentrations, which was read at 517nm. An average concentration of 72 Oxidative Stress and Chronic Degenerative Diseases - A Role for Antioxidants those used for standard curve analysis was chosen for the initial concentration of the metha nol extract from leaves of Morinda citrifolia. Through a mathematical analysis of linear regression curve was obtained concentration vs. Oleifera leaves was carried out in methyl alcohol for the phytochemical sieve, the results are shown in the following table (Table 2), and qualitative tests that were performed for each secondary metabolite are named in the same table.

Description of those plants collected in Mxico and presenting high content of antioxidant compounds 6. Azadirachta indica Active compounds of Neem have been identified while others have not, and analyzed the most common are: nimbin; nimbidin; ninbidol; gedunin; sodium nimbinate; queceretin; sal annin and azadirachtin. Fruits from Neem Tree The flowers are astringent and expectorant and also Seed oil is extracted. Flowers from Neem Tree Neem kills some infectious organisms, contributes to the immune response at various levels, this increases the possibility that the body fight bacterial infections alone, viral and fungal. Neem increases the production of antibodies, improves the response of immune cells that release mediators white blood cells. For Diabetes: Neem extract orally reduces insulin re quirements by between 30% and 50% to people who are insulin dependent. With Cancer: polysaccharides and limonoids found in the bark, leaves and Neem oil reduces tumors and cancer [39]. Passiflora edulis Sims Another plant which has been described with therapeutic applications is the genus Passi flora, whics comprises about 500 species and is the largest in the family Passifloraceae. Passi flora edulis Sims is native from the Brazilian Amazon, known by the common name for passion fruit [40, 41]. The word passion comes from the Portuguese- Brazilian passion fruit, which means food prepared in Totuma [41, 42]. Leaves and flower of passion fruit The ethnopharmacological information reveals that Passiflora edulis Sims has been used in traditional medicine around the world. In India, the fresh leaves of this plant are boiled in small amount of water and the extract is drunk to treat dysentery and hypertension, and the fruits are eaten to relieve constipation. The flowers are nocturnal, appear only on copies of more than two meters high and are colored green, but in the four seasons can take a pink color, the stem prolifera tion and leads to masses of slender spines long they can get to cover it completely. These plants are drought resistant so as to avoid daily water ing and exposure to damp, besides being very sensitive to frost. It is endemic to Baja California Sur, Baja California and Sonora in Mexico and Arizona in the United States It is a common species that has spread efficiently over the worldwide. The fruits are edible, but are hard to come by competition with birds and in sects. Southeastern Mexican indians prepare a tea from the pulp and skin of the cactus to relieve arthritis.

Air-borne spread Examples are infection with Legionella, Coxiella and in Air-borne spread is the dissemination of a some circumstances tuberculosis. Microbial aerosols are suspensions of particles that may remain suspended in the air for long periods of time. Particles in the range of 15 microns are easily drawn into the alveoli and may be retained there. Droplets and other larger particles that tend to settle out of the air are not considered air-borne.
