OBJECTIVE: To study the protective effect of electroacupuncture (EA) along the visual conductive pathway for the optic nerve tissue of anterior ischemic optic neuropathy (AION) in terms of the structure and apoptosis. METHODS: The AION model of right eye was established with laser in 48 New Zealand white ear rabbits. All rabbits were randomly divided into a model group, an acupuncture group and an acupuncture combined with EA group, 16 rabbits in each one. Other 16 normal left eyes were selected as a blank group...

Myasthenia gravis is a rare acquired autoimmune pathology causing neuromuscular transmission impairment. Juvenile onset of myasthenia gravis is often characterized by ocular involvement. We report two cases of ocular juvenile myasthenia gravis (JMG) in two siblings. They were two young girls, XA and XB, aged 11 and 9 years, of Malian origin, residing in Togo, born from first-degree of consanguinity presenting to Ophthalmology due to progressive decrease in visual acuity. XA showed visual acuity 8/10 on both eyes while XB showed improvement in visual acuity from 3/10 to 7/10 using a pinhole occluder, suggesting ametropia...

Toll-like receptors (TLRs) are extremely significant pattern recognition receptors. When nerve injury occurs, a variety of inflammatory factors are generated, leading to an exceedingly complex micro-environment. TLRs recognize damage-associated molecular patterns. To investigate the correlation between TLR4 and recovery after sciatic nerve injury, the model of sciatic nerve injury was conducted using TLR4-mutated mice (C3H/HeJ) and wild mice (C3H/HeN). Our goal was to identify short-stage and long-stage changes after sciatic nerve injury, mainly by checking the expression changes of inflammation factors in the short-stage and the differences in the recovery of the injured sciatic nerve in the long-stage...

Chronic inflammation has a crucial role in cancer development and the progression of various tumors, including pancreatic ductal adenocarcinoma (PDAC). The arachidonate cascade is a major inflammatory pathway that produces several metabolites, such as prostaglandin E2 (PGE2 ). The enzyme 15-hydroxyprostaglandin dehydrogenase (15-PGDH) degrades prostaglandin and is frequently decreased in several types of cancer; however, the molecular mechanisms of 15-PGDH suppression are unclear. The current study was conducted to elucidate the molecular mechanisms and clinical significance of 15-PGDH suppression in PDAC...

BACKGROUND: Cephalosomatic anastomosis or what has been called a "head transplantation" requires full reconnection of the respective transected ends of the spinal cords. The GEMINI spinal cord fusion protocol has been developed for this reason. Here, we report the first randomized, controlled study of the GEMINI protocol in large animals. METHODS: We conducted a randomized, controlled study of a complete transection of the spinal cord at the level of T10 in dogs at Harbin Medical University, Harbin, China...

This study aimed to determine whether nerve regeneration by means of an artificial nerve conduit is promoted by ethanol-induced cervical sympathetic ganglion block (CSGB) in a canine model. This study involved two experiments-in part I, the authors examined the effect of CSGB by ethanol injection on long-term blood flow to the orofacial region; part II involved evaluation of the effect of CSGB by ethanol injection on inferior alveolar nerve (IAN) repair using polyglycolic acid-collagen tubes. In part I, seven Beagles were administered left CSGB by injection of 99...

OBJECTIVE The use of nerve transfers versus nerve grafting for neonatal brachial plexus palsy (NBPP) remains controversial. In adult brachial plexus injury, transfer of an ulnar fascicle to the biceps branch of the musculocutaneous nerve (Oberlin transfer) is reportedly superior to nerve grafting for restoration of elbow flexion. In pediatric patients with NBPP, recovery of elbow flexion and forearm supination is an indicator of resolved NBPP. Currently, limited evidence exists of outcomes for flexion and supination when comparing nerve transfer and nerve grafting for NBPP...

The present study aimed to investigate the antidepressant effects of XYS in a rat model of chronic unpredictable mild stress (CUMS) and the underlying mechanisms. MATERIALS AND METHODS: A CUMS rat model of depression was established via 4 weeks of unpredictable stimulation. Then the rats were orally administered paroxetine and XYS for 2 weeks with continued stress...

BACKGROUND: Neuropathy of the ulnar nerve at the elbow is one of a number of muscle-related and nerve-related disorders that affect people performing intensive work with their hands and upper extremities, and is the second most prevalent peripheral nerve mononeuropathy. There are several classification systems currently being used by the medical community for patients with neuropathy of the ulnar nerve at the elbow. However, few of these classification systems include the clinical electrophysiologic parameters nerve conduction (NCS) and electromyographic (EMG) studies...

Introduction Improving axonal outgrowth and remyelination are crucial for peripheral nerve regeneration. Miconazole appears to enhance remyelination in the central nervous system. This study aims to evaluate the effect of miconazole on axonal regeneration using a sciatic nerve crush injury model in rats. Methods Fifty Sprague-Dawley rats were divided into control and miconazole groups. Nerve regeneration and myelination were determined using histological and electrophysiological assessments. Evaluation of sensory and motor recovery was performed using the pinprick assay and sciatic functional index...

Docetaxel is a taxane chemotherapeutic agent used in the treatment of breast cancer, prostate cancer and gastric cancer, but several side effects such as peripheral neurotoxicity could occur. The present study was designed to investigate the therapeutic potential of phosphatidylcholine (PC) on docetaxel-induced peripheral neurotoxicity. Rats were randomly divided into three groups and treated for 4 weeks. Behavioral tests were conducted to measure the effects of PC on docetaxel-induced decreases in mechanical & thermal nociceptive threshold...

Guillain-Barre Syndrome is very rare in parasitic and rickettsial infection. Here we report a case of Plasmodium falciparum and scrub typhus mixed infection, presented with quadriparesis. Clinical, Serological, CSF analysis and Nerve Conduction Studies were consistent with Acute Inflammatory Demyelinating Polyneuropathy (variant of GBS). After administration of antimalarials and antibiotics for the mixed infection, patient gradually improved.

Aim: Scant information is available about the prevalence of diabetic polyneuropathy, as well as the applicability of screening tools in sub-Saharan Africa. We aimed to investigate these issues in Zanzibar (Tanzania). Methods: One hundred consecutive diabetes patients were included from the diabetes clinic at Mnazi Mmoja Hospital. Clinical characteristics were recorded. Further, we investigated: a) self-reported numbness of the lower limbs, b) ten-point monofilament test, c) the Sibbald 60-s Tool and d) nerve conduction studies (NCS, using an automated handheld point-of-care device, the NC-stat DPNCheck)...

Background and Purpose: The purpose of the study is to determine whether the clinical profile of patients with carpal tunnel syndrome (CTS) has been same over the years with the help of routine and comparative electrodiagnostic tests. Methods: A prospective study of 100 patients with suspected CTS was conducted without controls. Three provocative maneuvers were performed. Routine and comparison nerve conduction tests were performed, i.e., second lumbrical interossei motor latency difference (2 LIMLD), digit 4 median-ulnar sensory latency difference (D4MUSLD), palm wrist distal sensory latency difference (PWDSLD), and digit 1 median-radial sensory latency difference (D1MRSLD)...
