Hydroxydeoxy-guanosine, which are indicators of inflammation and oxidative stress, in patients with essential hypertension.24 Olmesartan, an angiotensin-II subtype 1 receptor blocker, significantly reduced serum levels of CRP, TNF-, and monocyte chemotactic protein1.25 Graninger et al26 observed that losartan and enalapril decreased plasma levels of circulating intercellular adhesion molecule-1 c-ICAM-1 ; and vascular adhesion molecule-1 c-VCAM-1 ; . These results indicate that ACE inhibitors and angiotensin-II receptor blockers antagonists suppress inflammation and thus, are able to prevent not only renal injury and progression of renal disease in patients with hypertension and diabetes mellitus but also suppress atherosclerosis. Polyunsaturated fatty acids regulate ACE activity Previously, I showed that polyunsaturated fatty acids PUFAs ; inhibited leukocyte ACE activity.27 This suggests that PUFAs could function as endogenous regulators of ACE activity, and thus regulate the formation of Ang-II. PUFAs enhance nitric oxide generation.28 Hence, when cell tissue concentrations of PUFAs are low, the activity of ACE will be high leading to the formation of increased amounts of Ang-II. Plasma concentrations of PUFA are low in hypertension, diabetes mellitus, renal diseases, rheumatoid arthritis, lupus; psoriasis, eczema, atopic and non-atopic dermatitis; atherosclerosis, insulin resistance, obesity; dementia, schizophrenia, bipolar disorders, Huntington's disease, Alzheimer's disease; peptic ulcer disease; and cancer.28-32 A 25-nucelotide ACE deletion-deletion polymorphism increases ACE activity and such individuals showed a higher risk of developing stroke, obesity, emphysema, bipolar affective disorders, and cancers.33, 34 Thus, in various clinical conditions the twin abnormality of low PUFA content and increased ACE enzyme activity could occur that leads to high tissue levels of Ang-II. High Ang-II levels activate NADPH oxidase that in turn causes enhanced formation of ROS and decrease in nitric oxide levels. Enhanced ACE activity and Ang-II levels and decreased cell tissue content of PUFAs cause an increase in the generation of TNF-, IL-1, and IL-6, which initiate and perpetuate inflammation and tissue damage. Enhanced levels of Ang-II and a deficiency of PUFAs will lead to an increase in the generation of TNF-, IL-1, and IL-6 due to the stimulatory action of Ang-II and absence of negative feedback control that is exerted by fatty acids on the generation of these cytokines respectively.35-37 Kaergel et al 38 showed that transgenic rats overexpressing both human renin and angiotensinogen genes dTGR ; develop hypertension, inflammation, and renal failure and showed renal P450-dependent AA metabolism changes that led to decreased formation epoxy-eicosatrienoic acids 5, 6-, 8, and 14, 15EETs ; and hydroxyeicosa-tetraenoic acids 19- and 20HETEs ; that, in turn, inhibited IL-6 and TNF--induced.

Scientists supported in part by the National Institutes of Health's National Institute of Arthritis and Musculoskeletal and Skin Diseases NIAMS ; and National Institute of Neurological Disorders and Stroke NINDS ; have found that that the commonly prescribed blood pressure medication losaartan improves muscle regeneration and repair in a mouse model of Duchenne muscular dystrophy DMD ; , a devastating disease characterized by rapid progression of muscle degeneration in boys and young men. The research is based on similarities in the mechanism of DMD and another rare disease -- Marfan syndrome -- and the discovery that losartzn is effective in blocking the key mechanism in animal models of both diseases. Further studies of the drug, scientists emphasize, are needed to assess its value in patients. Marfan syndrome is a heritable connective tissue disorder affecting many organ systems, resulting in dislocation of the lens of the eye; progressive dilation of the aorta, which puts the aorta at risk of rupture; and small, weak muscles, says Harry C. Dietz, M.D., an author of the study in the February 2007 edition of Nature Medicine. Until recent years, scientists believed that Marfan syndrome was caused by weakness of tissues, says Dr. Dietz, the Victor A. McKusick professor of genetics in the McKusick-Nathans Institute of Genetic Medicine at the Johns Hopkins University School of Medicine and director of the William S. Smilow Center for Marfan Syndrome Research. But research by Dr. Dietz and his colleagues, and funded by the National Heart, Lung, and Blood Institute, NIAMS and others, has shown that the disease is the result of excessive activity of a growth factor called TGF-beta in the muscles. "We found that muscles were abnormal; they had very small fibers and excess fibrosis -- excessive connective tissue, or scarring -- between the fibers. What we learned was that high TGF-beta levels were preventing a process called muscle regeneration." Normally, when a person damages their muscle or when they exercise and send a signal to the muscle to get bigger, the muscle is able to mobilize a population of muscle stem cells that proliferate and then fuse to each other and to damaged muscle fibers to rapidly accomplish muscle repair or muscle growth. In the presence of too much TGF-beta, however, the cells simply do not get the signal to accomplish this regenerative process, says Dr. Dietz. "We learned that simply blocking TGF-beta in a mouse model of Marfan syndrome could rescue muscle regeneration, normal architecture and muscle function." Previous studies have demonstrated that the muscles of dystrophic mice lose their ability to repair and regenerate efficiently, and as in the human, the muscle tissue is progressively replaced by scar tissue. Knowing that the same phenomenon occurred in Marfan syndrome, Ronald D. Cohn, M.D., assistant professor of pediatrics and neurology at Johns Hopkins' McKusick-Nathans Institute of Genetic Medicine, and Dr. Dietz and their colleagues tried to see if they could extrapolate findings from the Marfan syndrome mouse model to a mouse model of DMD. Their research paid off. They were able to find evidence that excessive TGF-beta had a role in limiting muscle regeneration in response to damage in DMD as well. When the researchers gave the mice loasrtan to inhibit TGF-beta, they showed that the muscle was able to regenerate and repair much more efficiently. What's more, when they treated the mice with the drug over a period of time, the entire disease was attenuated, says Dr. Cohn. "Here we had two completely different myopathies -- muscle diseases -- that seemed to show a common pathway, which inhibits the repair process of skeletal muscle." Losartan, a frequently prescribed and well-tolerated drug in humans, works to reduce high blood pressure.
Size and the relatively short follow up. However, the recently reported ELITE II mortality study failed to show that treatment with losartan was superior to captopril, although it confirmed improved tolerability with losartan. ACE inhibitors, therefore, remain the treatment of choice in patients with left ventricular systolic dysfunction, although angiotensin II receptor antagonists are an appropriate alternative in patients who develop intolerable side effects from ACE inhibitors and tranexamic.

How can you tell if you need help? One approach is to have a family member or close friend who knows you well answer the 11-question checklist on page 23. You may wonder why someone else is answering the questions for you. Alzheimer's disease can interfere with one's ability to accurately observe one's functioning. The Symptoms of Dementia Screener SDS ; has been shown to be a helpful method for identifying dementia when completed by someone close to the person who may be developing dementia. While a screening questionnaire cannot replace diagnosis by a qualified clinician, this Symptoms of Dementia Screener can help identify the presence of a pattern of symptoms often found in Alzheimer's disease. A doctor can help put the symptoms and signs in context. If the score indicates that you may be experiencing symptoms of AD, we strongly encourage you to seek further evaluation. A full evaluation of medical, neurologic and psychiatric factors in the context of social and cultural aspects of your life should be done before a diagnosis of Alzheimer's disease is made. Answering "Yes" to 5 or more questions suggests the presence of dementia. Responses to this checklist do not offer a diagnosis of dementia or AD, but suggest the need for further evaluation. You are encouraged to discuss any questions or concerns with your healthcare professional. Bring this memory problems checklist with you when you speak to your doctor, for example, losartan muscle. In the sexually dysfunctional group, the selfreported degree of sexual satisfaction increased significantly from 7% of patients at baseline to 58% after 12 weeks' therapy. Erectile dysfunction was reported by 75% of this group before, and 12% after, losartan treatment and cytotec.
