Varves form only in fresh or brackish water, because the high levels of salt in normal sea water coagulate the clay into coarse grains. Since the saline waters leave coarse particles all year, it is nearly impossible to distinguish the individual layers in salt waters.
An aspartate aminotransferase (AST) test measures the amount of this enzyme in the blood. AST is normally found in red blood cells, liver, heart, muscle tissue, pancreas, and kidneys. AST formerly was called serum glutamic oxaloacetic transaminase (SGOT). Low levels of AST are normally found in the blood. When body tissue or an organ such as the heart or liver is diseased or damaged, additional AST is released into the bloodstream. The amount of AST in the blood is directly related to the extent of the tissue damage.
Serum Glutamic Oxalocetic Transaminase(SGOT) or AST is an enzyme found primarily in the liver, heart, kidney, pancreas, and muscles. Its normal reference range is Normal Adult Range: 0 - 42 U/L Optimal Adult Reading: 21.ormal Adult Range: 0 - 48 U/L Optimal Adult Reading: 24. In your case,SGPT levels are greater than SGOT. Alcohol is one of the most important offending agent for liver, but it typically causes a rise in SGOT which is more than SGPT (SGOT/SGPT ratio is more than 2).So in your case,alcohol is not the offending agent.
