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.
AST (SGOT) and ALT (SGPT) are sensitive indicators of liver damage from different types of disease. In rare cases, higher-than-normal levels of these liver enzymes may have causes other than liver problems. The interpretation of elevated AST and ALT levels depends upon the whole clinical picture.
