Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Willing and able to give written informed consent
  • Age 18 years to 75 years.
  • Both males and females.
  • Ankle branchial index of 0.8 or above.

You may not qualify if:

  • Diabetics will be excluded as the Ankle Branchial Index (ABI) result is considered an unreliable due the possible presence of arteriosclerotic plaques (lead pipe rigidity).
  • Patients who have participated in experimental drug studies within 30 days of entering this study.
  • receiving chemotherapy or radiotherapy for malignant diseases or any other indication
  • Patients taking corticosteroids or other immunosuppressive medications
  • Clinically malnourished patients or those with recent (last 4 weeks without treatment) serum albumin of less than 30g/l.
  • Patients with current or past history of acute deep vein thrombosis.
  • Patients with current signs and/or symptoms of cardiac, renal or hepatic failure. Renal failure defines as Creatinine
  • Patients with signs and/or symptoms of peripheral neuropathy.
  • Patients with signs and/or symptoms of ATROPHIE BLANCHE or other conditions associated with non-chronic venous insufficiency ulceration of the lower leg.
  • Patients with signs and/or symptoms of immunocompromized sates or recent (last 4 weeks ) T cell subset (CD4) count of less than 200 cells / ml.
  • Patients showing clinical signs and/or symptoms of anaemia or current or recent(last 4 weeks without treatment) haemoglobin level of less than 8g/dl
