TL;DR: Changes in PV calculated from the increase in plasma protein concentration averaged 7.5(z compared with 12.2 y0 calculated from changes in Hb and Hct, the difference could be accounted for by a loss of 6v10 plasma protein from the circulation.
Abstract: DILL, D. B., AND I>. L. &STILL. Calculation of pcrccntage changes in volumes of blood, plasma, and red cells in dehydration. J. Appl. Physiol. 37(2): 247-248. 1974.-Observations on hematocrit (Hct) and hemoglobin (Hb) were Inade in six men before and after running long enough to cause a 4y0 decrease in body weight. Subscripts B and A were used to denote before dehydration and after dehydration, respectively. Relations were derived between BVn, BVA, Hbn, HbA, Hctg, and HctA with which one can calculate the percentage decreases in BV, CV, and PV, as well as the concentration of hemoglobin in red cells, g. 100 ml-l (MCHC). When subjects reach the same level of dehydration the water loss from the various body compartments may vary reflecting difference in salt losses in sweat. Changes in PV calculated from the increase in plasma protein concentration averaged 7.5(z compared with 12.2 y0 calculated from changes in Hb and Hct. The difference could be accounted for by a loss of 6v10 plasma protein from the circulation.

TL;DR: Much of the growth-promoting activity of dialyzed serum is directly or indirectly derived from platelets, which has important implications for the response of arteries to localized injury and provides a key to further understanding of the role of factors derived from blood serum in promoting cell proliferation in vitro.
Abstract: Dialyzed serum from clotted monkey blood (“blood serum”) promotes the proliferation of monkey arterial smooth muscle cells in culture, but dialyzed serum prepared from recalcified platelet-poor plasma (“plasma serum”) is much less effective. Addition of platelets and calcium to platelet-poor plasma increases the activity of plasma serum to the same level achieved with blood serum. Furthermore, addition to plasma serum of a platelet-free supernatant prepared by exposing purified platelets to thrombin also stimulates the proliferation of smooth muscle cells. Thus, much of the growth-promoting activity of dialyzed serum is directly or indirectly derived from platelets. This finding has important implications for the response of arteries to localized injury and provides a key to further understanding of the role of factors derived from blood serum in promoting cell proliferation in vitro.
