Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (âwater-lovingâ). Lipids, however, are hydrophobic (âwater-fearingâ). Some lipids are amphipathicâpart of their structure is hydrophilic and another part, usually a larger section, is hydrophobic.
The high specificity at 10 and 11 mmindicates that lymph nodes of this size are almostalways metastatic in this level.A study of level II lymph nodes shows that for thewhole population a minimum diameter of 8 mm givesa relatively high sensitivity and specificity of 81% and80%, respectively.e found that a minimum axialdiameter of 7 mm for level II and 6 mm for the rest ofthe N0 neck represented the best compromise be-tween sensitivity and specificity. However, the size oflymph nodes was not an accurate predictor of metas-tasis in the N0 neck.
They play an important role in immunologic reactions. Normal lymphocyte count is in the rage between 16-45% of white blood cells (WBCs). Increased lymphocytes (lymphocytosis) in adults is defined as an absolute lymphocyte count greater than 4,000/mm3.It is necessary to distinguish between absolute and relative lymphocytosis.Absolute lymphocytosis may be defined as an increase in blood lymphocytes above 4,000/mm3.ncreased lymphocytes (lymphocytosis) in adults is defined as an absolute lymphocyte count greater than 4,000/mm3. It is necessary to distinguish between absolute and relative lymphocytosis. Absolute lymphocytosis may be defined as an increase in blood lymphocytes above 4,000/mm3.
