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. We also see increased levels in mononucleosis, alcoholism, liver damage, kidney infection, chemical pollutants or myocardial infarction.
A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6.
A perfect number: a number is perfect when the sum of its divisors (except the number itself) equals the given number. Theorem connecting perfect and prime numbers. 1  6 : The divisors of 6 are 1,2,3 & 6. To show that this is a perfect number we could all the divisors except the number itself.  1+2+3 = 6.
