The reduced organ function following delayed nerve repair highlights the need for pharmacological interventions. In this regard, many chemical agents have been administered after nerve injury; however, their functional outcomes are not satisfying yet. The present study aimed to evaluate the effects of the administration of citicoline and atorvastatin on the regenerative capacity of the distal end of the transected sciatic nerve throughout a delayed nerve repair period.

The sciatic nerve of male rats (250-300 g) was transected, and the animals were intraperitoneally administrated citicoline (200 mg/kg, n=5), atorvastatin (5 mg/kg, n=5), citicoline + atorvastatin, and vehicles (control groups 1 and 2, n=5) for one month. In the sham group (n=5), the sciatic nerve was only exposed. After one month, the transected nerve was repaired. Fourteen weeks after surgical repair, morphometric and electron microscopic evaluations were performed on the nerve.

In the present study, improvement in the structural (fiber diameter, axon diameter, and myelin thickness, etc.) and ultrastructural (degree of myelin destruction) indices of the distal segment of the nerve was observed in the citicoline and atorvastatin groups compared to the control groups (P< 0.01). In addition, the nerve structural and ultrastructural indices in the citicoline + atorvastatin group were better than each citicoline and atorvastatin group.

The results of this study showed that the administration of citicoline and atorvastatin leads to maintaining the regeneration capacity of the distal part of the nerve in the condition of delayed nerve repair

Peripheral nerve injuries are among the most common types of injuries of the nervous system and are regarded as the main cause of disability. These injuries can lead to disorders in muscles movement and normal sense, and also painful neuropathy. Tissue engineering and stem cells therapy are among the treatment methods for these disorders. In this study we assessed sciatic nerve restoration through a silicone tube containing a fibrin scaffold filled with Schwann cells and citicoline by using electromyography and histological methods. 50 adult male Wistar rats were randomly divided into five groups. 1. Silicon tube. 2. Silicon tube with fibrin gel. 3. Silicon tube with Schwann cells. 4. Silicone tube with citicoline. 5. Silicon tube with Schwann cells & citicholine. The left sciatic nerve was cut and a 10 mm gap was created. A silicon tube was placed between the two cut ends of the nerve, as a guide channel. Allografted Schwann cells and citicoline were injected into the guide channel. The third and fifth groups were significantly different from other groups in regard to the amplitudes of the waves (P <0.05). Also, we found significant decreases in the latency of the waves recorded in the 1st to 4th groups (P <0.05). There was a significant difference between the third and fifth groups in the results of histological examination (P <0.05). Increased amplitude in the third and fifth groups indicated better restoration of the nerve in these groups. Also reduced latency in the 1st to 4th groups was indicative of regeneration of the sciatic nerve. Histologic results revealed increased number of recovered axons in the fifth group which was indicative of the better outcome of the combination therapy.

Evidence is indicative of the positive effect of citicoline administration in stroke patients; however, there are controversies over this issue. Regarding this, the present study was conducted to investigate the efficacy of citicoline in acute stroke patients.
This randomized clinical trial was conducted on 160 patients with hemorrhagic and ischemic stroke. The participants were randomly assigned into two groups of intervention and control. The intervention group daily received 1 g citicoline injections for 10 days, in addition to the standard therapy. The baseline severity of the disease was determined by the National Institutes of Health Stroke Scale, and the outcome of the disease was assessed using the Modified Rankin Scale and Barthel Index on the 1st, 10th, and 90th days post-intervention. Statistical analysis was performed using Stata software (version 11.1). P-value less than 0.05 was considered statistically significant.
According to the results, there was no significant difference between the two groups in terms of gender, mean age, hypertension, diabetes, smoking, hyperlipidemia, and mortality after stroke (P>0.05). Regardless of the type of stroke, the severity of the disease decreased over time in both groups. However, at the end of the study (the 90th day), the intervention group had lower disease severity, compared to the control group (P Based on the findings of this study, the use of citincoline in acute stroke patients exerted no significant effect in the disease treatment in the short term. However, the long-term administration of this medication could result in significant impacts on the treatment of the patients, especially those with ischemic stroke, and improvement of their efficacy.
