Here's a quote: Most normal persons have detectable concentrations of circulating CEA. Approximately 85% of adults have CEA levels less than 2.5 ng/mL, while 95% have levels less than 5.0 ng/mL. CEA levels are slightly higher in men than women. The median level is 3.4 ng/mL in men and 2.5 ug/mL in women. Healthy persons seldom have levels above 10 ng/mL.
Ginkgo biloba, known as ginkgo or gingko and also as the maidenhair tree, is the only living species in the division Ginkgophyta, all others being extinct.It is recognizably similar to fossils dating back 270 million years. Native to China, the tree is widely cultivated and was introduced early to human history.he leaves are usually 5â10 cm (2.0â3.9 in), but sometimes up to 15 cm (5.9 in) long. The old popular name maidenhair tree is because the leaves resemble some of the pinnae of the maidenhair fern, Adiantum capillus-veneris. Ginkgos are prized for their autumn foliage, which is a deep saffron yellow.
