A Non-Newtonian mathematical Model on the two phase renal mean blood flow in renal arterioles with special reference to Kidney Infection (UTI)

چکیده
In this paper, we have presented a model of two phased blood flow in renal arterioles remote from the heart and proximate to the Kidney keeping in view the nature of renal blood circulation in human body. If blood flows arterioles to capillaries then blood pressure drop arises in human body the viscosity increases in the arterioles due to formation of roulex along axis by red blood cells, as we know the arterioles are remote from heart and proximate to the kidney. P.N. Pandey and V. Upadhyay have considered the blood flow has two phased , one of which is that of red blood cells and other is Plasma .They have also applied the Herschel Bulkley non –Newtonian Model in bio-fluid mechanical set-up . We have applied the Campbell-Pitcher two phase model in biofluid mechanical setup which is realistic in so for as the blood flow is considered to be two phased homogenous mixture of blood cells and plasma .We have collected a clinical data in case of Kidney Infection (UTI) for Hematocrit v/s Blood Pressure drop. The overall presentation is in tensorial form and solution technique adapted is analytical as well as numerical. The role of Hematocrit is explicit in the determination of blood pressure in case of renal disease – Kidney Infection (UTI).The graphical presentation for particular parametric value is much closer to the clinical observation.

Background: Urinary tract infection (UTI) is one of the most important pediatric health problems, which is occasionally associated with irreversible renal damage. Dimercapto-succinic acid (DMSA) scan is a diagnostic standard for the renal scar. Doppler ultrasonography (D.S) has been considered as a less invasive method. The purpose of this study was to determine the sensitivity and specificity ...

Background: Urinary Tract Infection (UTI) is one of the major etiological factors of permanent kidney impairment, resulting in renal scarring and severe and pernicious side effects, such as arterial hypertension and renal failure. The purpose of this study was to clarify the impression of renal parenchyma involvement by first UTI (on the basis of acute DMSA scan) and vesicoureteral reflux (VUR-...
