| Outline of Final Research Achievements |
We examined the effects of hypertension on the progression of alcoholic liver injury using the spontaneously hypertensive rat (SHR) and normotensive Wistar-Kyoto rat (WKY) as control. As a result, chronic ethanol treatment in SHR induced hepatosteatosis with liver injury and sympathetic hyperactivity, as evidenced by increased in the accumulation of fatty droplets within hepatocytes and pericellular hepatic fibrosis with liver injury, increased in gene or protein expressions such as activated hepatic stellate cells, TNF-α, TGF-β1,collagen, adrenergic α receptor, neuropeptide Y and tyrosine hydroxylase. These results suggested that chronic ethanol treatment in SHR could induce the more severe liver injuries. In conclusion, chronic alcohol intake and hypertension could be possible to deteriorate mutually each pathological state via the sympathetic overactivity.
