Neural tissues, vitamin

Oxidative stress is suggested to play a major role in the pathogenesis of AD. Vitamin C has been regarded as the most important antioxidant in neural tissue. Vitamin C decreases p-amyloid generation and acetylcholinesterase activity and prevents endothelial dysfunction by regulating nitric oxide. Clinical trials with different antioxidants, including vitamin C, yielded confusing results [485],... 

Hydralazine (Apresoline) Directly relaxes arterioles (not veins) independent of sympathetic interactions. Causes decrease in blood pressure leading to reflex tachycardia and increased cardiac output. Directly increases renal blood flow. Moderate hypertension. May be used in pregnant women who are hypertensive. Reflex tachycardia, palpitations, fluid retention, systemic lupus erythematosis-liKe syndrome. Chronic therapy may lead to peripheral neuritis (due to interference with vitamin B6 metabolism in neural tissue). 

The symptoms of vitamin E deficiency in animals are numerous and vary from species to species (13). Although the deficiency of the vitamin can affect different tissue types such as reproductive, gastrointestinal, vascular, neural, hepatic, and optic in a variety of species such as pigs, rats, mice, dogs, cats, chickens, turkeys, monkeys, and sheep, it is generally found that necrotizing myopathy is relatively common to most species. In humans, vitamin E deficiency can result from poor fat absorption in adults and children. Infants, especially those with low birth weights, typically have a vitamin E deficiency which can easily be corrected by supplements. This deficiency can lead to symptoms such as hemolytic anemia, reduction in red blood cell lifetimes, retinopathy, and neuromuscular disorders.
