Progesterone Treatment After Experimental Spinal Cord Injury
No full textObjective/Background:A growing list of studies gives evidence for the efficacy of progesterone in the nervous systems. Neuroprotective effects of progesterone are well documented for the injured brain models in the literature. However, the effects of progesterone on spinal cord injury (SCI) should be investigated.Methods:Twenty adult male Wistar-Albino rats were included in the study. The rats were randomly allocated into two groups (Control and Progesterone). Progesterone was administered in five days at a dose of 4 mg/kg via intraperitoneal route. Each group underwent motor examination in sixth weeks using Basso, Beattie and Bresnehan (BBB) locomotor test.Results:The score mean values of the control and study groups receiving progesterone treatment after six weeks were 11.40.427 and 14.1 +/- 0.526, respectively (P<0.05). While the improvement process showed a nearly parallel course between the two groups until the end of the third week, the progesterone treated group exhibited a significant difference in BBB scores relative to the control starting from the fourth week (P<0.05). On the examined histological sections, it was determined that progesterone had clear neuroprotective effects.Conclusions:The results supported the fact that progesterone could be a potentially effective therapeutic strategy to treat SCI
Effect of Pregabalin in Preventing Secondary Damage in Traumatic Brain Injury: An Experimental Study
No full textBackground: In this study we aimed to explore the effects of pregabalin on a traumatic brain injury model in rats. Material/Methods: This study included 40 adult male Sprague-Dawley rats randomized into 4 groups, each of which contained equal numbers of animals. The control group had no head trauma and thus was not treated. The trauma group had head trauma but was not treated. The pregabalin group had no head trauma but was treated by pregabalin. The trauma + pregabalin group had head trauma treated with pregabalin. The biopsy samples taken from the study animals were histopathologically examined for the presence of edema, inflammation, and neuronal damage. Results: All animals in the trauma group had edema, inflammation, and neuronal damage. Four subjects in the control group, 6 in the pregabalin group, and 4 in the trauma + pregabalin group had edema; inflammation was present in 1 subject in the control group, 3 subjects in the pregabalin group, and 3 subjects in the trauma + pregabalin group; neuronal damage existed in 1 subject in the control group, 1 subject in the pregabalin group, and 6 subjects in the trauma + pregabalin group. The trauma group had significantly higher edema and neuronal damage scores than the other groups. Similarly, inflammation was significantly more prevalent in the trauma group than the control and trauma + pregabalin groups. Conclusions: The results of the present study indicated anti-edema, anti-inflammatory, and neuroprotective effects of pregabalin in an experimental head trauma model in rats. Pregabalin may thus be beneficial in humans with acute TBI by relieving concomitant edema and inflammation
A new described mechanisms of intestinal glandular atrophy induced by vagal nerve/Auerbach network degeneration following subarachnoid hemorrhage: The first experimental study
No full textStress ulcers is a trouble complication of subarachnoid hemorrhage (SAH). Although gastrointestinal ulcerations may be attributed to increased HCL secretion in SAH; the exact mechanism of that complication has not been investigated definitively. We studied if vagal network degeneration may cause intestinal atrophy following SAH. Study was conducted on 25 rabbits, with 5 control group (Group-A), 5 SHAM group (Group-B), and 15 SAH group via injection of autologue blood to cisterna magna. Seven animals followed for seven days (Early Decapitated-Group-C) and eight animals followed 21 days (Late Decapitated-Group-D). The vagal nodosal ganglia (NGs), Auerbach plexuses and goblet cells of duodenums were examined by current stereological methods and compared statistically. The mean numbers of degenerated axon density/mm(2) of gastric branches of vagal nerves was 8 +/- 2, 34 +/- 11, 189 +/- 49 and 322 +/- 81 in the Group A, B, C, and D respectively. The mean numbers of degenerated neuron density/mm(3) of NGs was 5 +/- 2, 54 +/- 7, 691 +/- 87 and 2930 +/- 410 in the Group A, B, C, and D respectively. The mean numbers of degenerated Auerbach neurons 2 +/- 1, 4 +/- 1, 12 +/- 3 and 27 +/- 5/mm(3) in the Group A, B, C, and D respectively. The mean numbers of degenerated goblet cells/mm(3) were 4.3 +/- 1.02, 11.5 +/- 0.26, 143 +/- 26 and 937 +/- 65 Group A, B, C, and D respectively. Statistical analysis showed that vagal network ischemia could cause intestinal bleeding and so atrophy in SAH progression. Statistical analyses of groups were; Group-D/Group-A < 0.001, Group-D/Group-B < 0.005, Group-C/Group-A < 0.005. Undiscovered effect of ischemic vagal network injuries should be regarded as a major cause of stress ulcerations following SAH which has not been mentioned in the literature. (C) 2018 Elsevier Ltd.

Protective effects of alpha-lipoic acid on experimental sciatic nerve crush injury in rats: assessed with functional, molecular and electromicroscopic analyses
No full textAim: The present study aimed to demonstrate protective effects of alpha lipoic acid on experimental sciatic nerve crush injury model assessed with functional and electronmicroscopy analyses. Methods: In this study, groups were; Group 1; sham operated, Group 2; applied only sciatic nerve crush (Control), Group 3; Sciatic nerve crush + treated ALA 25 mg/kg (received orally) and Group 4; Sciatic nerve crush + treated ALA 50 mg/kg. Subsequently, sciatic nerves crush injury induced by forceps. At the second and fourth week, all animals were evaluated for sciatic functional index (SFI) and histomorphometric analyses with electronmicroscopy. Results: The SFI was significantly increased for both ALA-treated groups 30 days post-injury compared with control groups. The elecronmicroscopy results demonstrated that the axon diameter, the myelin diameter, the area of regenerating axon and miyelin were better in the treatment group than in the control group. Also ALA decreased IL-1 beta and Caspase 3 levels that increased in SNC group. Conclusions: These results suggest that ALA neuroprotective agent for peripheral nerve injury (PNI) and promoted peripheral nerve regeneration via its anti-inflammatory and antiapoptotic effects
