Blood content

The normal arterial wall consists of the intima, media, and adventitia, as illustrated in Fig. 4—3A. The endothelium is located in the intima and consists of a layer of endothelial cells that line the lumen of the artery and form a selective barrier between the vessel wall and blood contents. The internal elastic lamina separates the intima and media, where vascular smooth muscle cells are found. The vascular adventitia comprises the artery s outer layer. Atherosclerotic lesions form in the subendothelial space between the endothelial cells and internal elastic lamina.

Another tactic is to compute a difference spectrum contrasting two measurements of a tissue region taken before and after some change in the blood content, as sketched in Fig. 16.4b. This provides a spectrum that is nominally...

Q10 The transfer of CO across the respiratory surface (TCo) can be used to estimate the efficiency of gas transfer in the lung. A small concentration of CO is added to inspired air it diffuses across the alveolar membranes into the blood. The increase in arterial blood content of CO over a short period of time is measured to estimate the rate of CO transfer. A small concentration of CO must be used as this gas combines strongly with haemoglobin at the same position as oxygen to produce carboxyhaemoglobin.

Hepatic blood flow amounts to ca. 1,200 ml/min in women and ca. 1,800 ml/min in men, depending on the physiological conditions. Of this blood, 70-75% are supplied by the portal vein and 20-25% by the hepatic vein. The oxygen supply is secured by the hepatic artery at 20 vol. % and the portal vein at 16-17 vol. %. The blood content is equivalent to 25-30% of liver weight. The liver blood volume accounts for 10-15% of the total blood content of the body - an extremely high proportion.

Blood and urine samples are often collected after the patient has fasted for a period of time (e.g., overnight), particularly for cholesterol or glucose analysis. One study indicates that an average breakfast has no significant effect on the concentration of the blood content of carbon dioxide, chloride, sodium, potassium, calcium, urea nitrogen, uric acid, creatinine, total protein, and albumin. Serum phosphorus is slighdy depressed at 45 min after the meal but not after 2 h. 

Ethanol is usually ingested through the gastrointestinal tract, but can be absorbed as vapor by the alveoli of the lungs. Ethanol is oxidized metabolically more rapidly than methanol, first to acetaldehyde, then to CO2. Ethanol has numerous acute effects resulting from central nervous system depression. These range from decreased inhibitions and slowed reaction times at 0.05% blood content of ethanol, through intoxication, stupor and—at more than 0.5% blood ethanol—death. 

The relative importance of thyroid uptake studies has fluctuated somewhat through the years. Probably the most commonly used test is a simple measurement of uptake in the thyroid at 3 or 4 hours and at 24 hours after a standardized dose of However, some centers favor a more sophisticated iodine clearance study where the thyroidal content is related to the blood content of I after intravenous injection. One limitation of the simple procedure was recognized many years ago when marked daily fluctuations of 3-hour and 24-hour uptakes were noted within individual subjects (Lll). 

Table 5 Low-Blood-Content Soybean Blend Glue Ingredients and Mixing Procedure... 

As with straight soybean glues, the low-blood-content formulation requires a mold-inhibiting ingredient to meet plywood performance standards, whereas the high-blood-content glue does not [24]. 

For the high-resin-content formulation (Table 12), a partial addition of the PF resin can be made just after the initial mix and before sodium hydroxide addition if more fluidity is needed for propeller-type stirring. This formulation is more properly termed a blood-fortified exterior PF resin adhesive for hot-pressing plywood or laminated veneer lumber [52]. Even in quantities this small, the effect of the animal blood is to reduce the hot-press curing time by 2(%30% over that of phenolic resins used alone. For purposes of adhesive solid, calculation, the blood content can legitimately be included with the phenolic resin solids. 

Robinson et al. (1977) found no deterioration of the renal function in Wistar rats under cotrimoxazole when they measured the blood content of urea. Neither in rats with normal renal function nor in those with operatively produced impairment of the kidneys was tubular necrosis found.
