Once the tolls on the canal had paid for its construction in 1882, they were eliminated. After the opening of the canal, additional canals were constructed to connect the Erie Canal to Lake Champlain, Lake Ontario, and the Finger Lakes. The Erie Canal and its neighbors became known as the New York State Canal System.
Serum Glutamic Pyruvic Transaminase or ALT is an enzyme found primarily in the liver but also to a lesser degree, the heart and other tissues. It is useful in diagnosing liver function more so than SGOT levels. Decreased SGPT in combination with increased cholesterol levels is seen in cases of a congested liver.
If the liver is injured or damaged, the liver cells spill these enzymes into the blood, raising the AST and ALT enzyme blood levels and signaling liver disease. Other blood tests pertaining to the liver are measurements of some of the other enzymes found the liver. In addition to AST and ALT, alkaline phosphatase, 5' nucleotidase, and gamma-glutamyl transpeptidase (GGT) are a few of the other enzymes located in the liver.
