The association of coronary artery disease (CAD) severity with increased C-reactive protein (CRP) and decreased albumin levels has been reported. However, to our knowledge, no study has investigated the usefulness of the CRP to albumin ratio (CAR) in predicting intermediate-high SYNergy between Percutaneous Coronary Intervention with TAXus and cardiac surgery (SYNTAX) score (SS) and high SS II. Consecutive patients (n = 344) treated with percutaneous coronary intervention comprised the study population. The study population was divided into 2 groups according to SS >22 and mean SS II values, respectively. Patients with intermediate-high SS and high SS II had higher CAR than patients with low SS and SS II. History of diabetes mellitus, decreased albumin, lower left ventricular ejection fraction, and elevated CAR (odds ratio [OR]: 1.020; 95% confidence interval [CI], 1.009-1.031; P < .001) were independent predictors of high SS. The presence of hypertension, decreased hemoglobin and albumin levels, and increased CAR (OR: 1.014; 95% CI, 1.004-1.023; P < .001) were independent predictors of SS II. In receiver operating characteristic curve comparison, CAR was superior to CRP and albumin in prediction of intermediate-high SS, but only CRP in prediction of high SS II. The CAR calculated from the admission blood samples could be a useful parameter for predicting CAD severity using SS and SS II.

PURPOSE:To assess and compare the histopathological effects of ozone therapy and/or methylprednisolone (MPS) treatment on regeneration after crush type sciatic nerve injury. METHODS:Forty Sprague-Dawley male rats were randomly allocated into four groups. Four groups received the following regimens intraperitoneally every day for 14 days after formation of crush type injury on sciatic nerve: Group I: ozone (20mcg/ml); Group II: methylprednisolone (2mg/kg); Group III: ozone (20 mcg/ml) and methylprednisolone (2mg/kg); Group IV: isotonic saline (0.9%). The histomorphological evaluation was made after biopsies were obtained from the sites of injury.RESULTS: Significant differences were noted between groups in terms of degeneration (p=0.019), nerve sheath cell atrophy (p=0.012), intraneural inflammatory cellular infiltration (p=0.002), perineural granulation tissue formation (p=0.019), perineural vascular proliferation (p=0.004), perineural inflammatory cellular infiltration (p<0.001) and inflammation in peripheral tissue (p=0.006).Degeneration was remarkably low in Group III, while no change in nerve sheath cell was noted in Group II. CONCLUSION:The combined use of methylprednisolone and ozone treatment can have beneficial effects for regeneration after crush type nerve injury.

Ozone showed beneficial effects on APAP hepatotoxicity at a statistically significant level. It is known that ozone has therapeutic effects in various diseases owing to its antioxidant effects. The present study suggests that ozone may be utilized as a routine supplementary therapy in acute APAP hepatotoxicity.

Neuronal cells are the main fundamental anatomic unit of the system. Nerve injuries are generally divided into three categories as neuropraxia, axonotmesis and neurotmesis. Neurotmesis is the most severe form. Schwann cells are activated within 24 hours of the injury and the healing cascade continued with the cells, which are stimulated by Schwann cells. And neurotrophic factors like nerve growth factor (NGF) have a crucial role in regeneration and degeneration processes. Additionally, Schwann cells upregulate the expression of some proteins, such as fibronectin, which are crucial for axonal regeneration. All this information about nerve healing sheds light on treatment studies. Iatrogenic nerve injury has an important place in peripheral nerve injury. Causes may be direct surgical damage, wrong intraoperative patient positioning, anaesthesiarelated reasons or limb tourniquets. Typical symptoms are motor or sensory deficits such as paraesthesia, weakness, paralysis and pain. Many of the traumatic nerve injuries require surgical repair. Direct nerve repair and autologous nerve grafts are still goldstandard treatment options. Additionally, nerve conduits are very successful to provide an ideal peripheral support for neuronal recovery but are still insufficient. In recent years, research efforts have focused on the neurotrophic factors and cell-based therapies to perform better microenvironment for neuronal healing.Keywords: peripheral nerve, injury, iatrogenic, nerve grafts, conduit, cell-based therapy IntroductionAn injury to a nerve can result in a problem with the muscle innervation or in a loss of sensation. In some people, it can also cause pain. The type of nerve injury will determine the type of treatment that will be needed. Peripheral nerve injuries (PNIs) affect all age groups and have many causes like trauma and medical disorders. The majority of the peripheral nerve injuries © 2017 The Author(s). Licensee InTech.

Typical symptoms are motor or sensory deficits such as paraesthesia, weakness, paralysis and pain [2]. Many of the traumatic nerve injuries require surgical repair. The primary goal of the repair is to achieve the reinnervation of the target organs, but the therapeutic options which are used at present cannot achieve perfect sensory and motor recovery in all cases. In this chapter, the pathophysiology and mechanisms of nerve injuries, the traumatic nerve injuries, especially the iatrogenic forms, and therapeutic options for the peripheral nerve injuries will be discussed. Peripheral nerve anatomyPeripheral nervous system consists of neuronal cells, glial cells and stromal cells. Neuronal cells are the main fundamental anatomic unit of the system.
