Comparison of two methods of epidural steroid injection in the treatment of recurrent lumbar disc herniation.

Study Design: Prospective study.

Purpose: We compared the effects of two methods of epidural steroid injection in patients with recurrent disc herniation.

Overview Of Literature: To our knowledge, there is no previous report of such a comparison in these patients.

Oral opium: an unusual cause of lead poisoning.

Introduction: The number of cases of lead poisoning (LP), a widely known disease with various aetiologies, being reported globally has decreased over the years due to both limited domestic applications of lead and enforcement of stringent safety measures. However, a new presentation of lead poisoning, lead-contaminated opium (LCO), is gradually emerging in our region. This study aimed to determine the prevalence and clinical effects of lead toxicity associated with opium use.

Vasorelaxant Effect of a Newly Synthesized Dihydropyridine Ethyl Ester (DHPEE) on Rat Thoracic Aorta: Dual Mechanism of Action.

Introduction: DHPEE is a newly synthesized compound by merging the key structural elements in an angiotensin receptor blocker (Telmisartan) with key structural elements in 1,4- dihydropyridine calcium channel blocker (Nifedipine). In this study, we examined dual calcium channel blocking and AT1 antagonist activity for DHPEE.

Methods: The functional inhibitory characteristics of DHPEE were studied in vitro in rat thoracic aorta preparations precontracted by phenylephrine (1μM) or KCl (80μM) or Ang II in normal or calcium-free solutions.
