New blood glucose levels focus specifications were made which have a keen Accutrend GC glucometer (Boehringer Mannheim, Mannheim, Germany). At least five sized blood sugar levels and you can simultaneous sized blood and you can plasma viscosity have been made for all of one’s dos9 times from the 0, 31, sixty, and you can 120 minute from the twenty-two°C, once consumption from 75 grams of glucose.
Analytical Review
Results of the first class had been evaluated statistically towards Student t ensure that you Spearman relationship test. The partnership between glucose levels quantity and you may viscosity was examined statistically with the Pupil t test, study off difference, and you may regression data.
Results
When the blood temperature decreased from 36.5° to 22°C, the mean blood free flow time increased from to sec (%). According to Poiseuille’s equation, the blood flow rate decreases %, and for the compensation of this ischemic state, a % BP increase or 5.9% vasodilation is needed. If viscosity (? in the denominator of the equation) changes from 100 to (%), the flow rate Q would decrease = %. If viscosity increases %, the pressure (F1 ? F2) value (multiplier in the equation) must be increased with the same percentage to keep the equation constant. When the viscosity increases %, to keep the flow rate constant, the radius of vessel (initial) a 4 , must increase %. The calculation of this increased radius (last) is a 4 final = 1.2613 ? a 4 initial. From this calculation, ?final = = 1.0597 and so, 5.97% vasodilation can be estimated.
In the event that temperature enhanced out-of thirty six.5° to 39.5°C, the latest bloodstream free circulate day diminished regarding so you’re able to sec (%). Inside condition, the fresh blood circulation rate improved %; considering Poiseuille’s formula, an effective % decrease in BP or 2.71% vasoconstriction try wanted to support the hemodynamic equilibrium lingering.
The correlation between temperature and blood viscosity is r = ?0.84, P < .001 when all the differences at the three temperatures are evaluated together (Fig. 1). When all of the blood free flow time data for the three temperatures were evaluated together according to age, there was a negative correlation (r = ?0.1381 and P < .05); when the data were evaluated according to sex, it was found that the mean blood free flow time in women was % less than that in men (r = 0.3408, P < .001).
Effect of temperature on blood viscosity. When blood temperature decreases from 36.5° to 22°C, blood viscosity increases %. If temperature increases from 36.5° to 39.5°C, blood viscosity decreases %. To make a more accurate presentation in the graphic representation and statistics, instead of the “relative viscosity” value, blood free flow time in seconds (s) was used https://datingranking.net/local-hookup/orlando/ as data. When all of the differences at three temperatures are evaluated together, a negative correlation is seen between blood temperature and viscosity (r = ?0.84, P < .001).
When the temperature decreased from 36.5° to 22°C, plasma free flow time rose from 4.81 to 5.71 sec (%); with a temperature increase from 36.5° to 39.5°C, it decreased from 4.78 to 4.57 sec (4.99%). A negative correlation was seen (r = ?0.9342, P < .001) when the plasma flow times at the three temperatures were evaluated together. With a temperature decrease from 36.5° to 22°C, erythrocyte free flow time increased from to sec (%). When the temperature increased from 36.5° to 39.5°C, erythrocyte free flow time decreased from to sec (9.92%). There was a negative correlation between temperature and erythrocyte free flow time (r = ?0.62, P < .001). All of the blood, plasma viscosity, and erythrocyte deformability differences due to temperature were statistically significant (P < .001).
