the purpose of this study was to investigate the potential responses of the cardiovascular system and regional blood flow to hypoxic hypoxia (bb) and to carbon monoxide (co)-induced hypoxia (coh). ten anesthetized cats were studied under two nonnoxic (control: cont) and two hypoxic conditions. four types of radioactive micro spheres were used to measure regional blood flow during cont and two h...

objective: to compare the effectiveness of letrozole and clomiphene citrate (cc) on uterine blood flow rate in patients with unexplained infertility. materials and methods: in this randomized clinical trial 90 women with unexplained infertility referred to a university clinic from january 2011- december 2013 were enrolled. thirty patients were randomized for letrozole, 30 patients for cc and 3o...

introduction : cerebral autoregulation (ca) and mean cerebral blood flow velocity in males and females are still under controversy. the present study was scheduled to address the effect of sex on these parameters. materials and methods : the present study was interventional and performed on 30 healthy volunteers (15 males aging from 20-30 yrs and mean age of 23.9±3 years old and 15 females agin...

The mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. To examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit.Cerebral blood flow was measured by laser Doppler flow-meter in 18 NZW rabbits anesthetized with sodium pentobarbital.  Tetrodetoxin ...

We used Laser Doppler flowmetry to measure the effect on the blood flow to the femoral head/neck junction of two surgical approaches during resurfacing arthroplasty. We studied 24 hips undergoing resurfacing arthroplasty for osteoarthritis. Of these, 12 had a posterior approach and 12 a trochanteric flip approach. A Laser probe was placed under radiological control in the superolateral part of ...

the use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...
