This frame has 48 mm lenses and a 24 mm bridge. Sometimes measurements will be written on the bridge tabs, especially on clear frames or women's frames. This one has a 46 mm lens width and an 18 mm bridge.Sometimes measurements will be written on the bridge tabs, especially on clear frames or women's frames. This one has a 46 mm lens width and an 18 mm bridge. On the temples, you'll see ''4 1/2 5 3/4'' or sometimes just ''7'', which is the longest temple I've found.ometimes measurements will be written on the bridge tabs, especially on clear frames or women's frames.

Increase in permeability of the cells of the collecting tubule to water is due to an increase in the production of antidiuretic hormone (ADH).   Aquaporins are constant com â¦ ponents of the tubule cells membranes. Unless ADH is present, aquaporins are virtually absent in the luminal membranes of the collecting duct.
Under the influence of vasopressin AQP2 migrate from the cytoplasm to the apical membrane. In nephrogenic diabetes insipidus there are AQP2 alterations. Antidiuretic action (V2): The ADH increases water permeability of collecting ducts in the cortical and medullary part of the kidney. It induces the incorporation of aquaporins in the apical membrane of collecting ducts and induces their opening, which allows water reabsorption.
