Effect and Mechanism of Glutamic Acid Injection Into Cerebellar Fastigial Nucleus on Chronic Visceral Hypersensitivity in Rats / 胃肠病学

Background:Cerebellar fastigial nucleus (FN)is involved in regulation of visceral activities such as cardiovascular, ingestion,respiratory,and acute gastric mucosal injury,yet it is unclear whether it participates in the regulation of visceral hypersensitivity and what is the possible mechanism. Aims:To investigate the effect and possible mechanism of glutamic acid (Glu ) injection into cerebellar FN on chronic visceral hypersensitivity in rats. Methods: Chronic visceral hypersensitivity rat model was established by neonatal colorectal distension (CRD). After 8 weeks,the rats were divided into CRD group,solvent group (0. 2 μL 0. 9% NaCl solution injection into cerebellar FN),high-,medium-,low-dose Glu groups (12,6,3 μg Glu injection into cerebellar FN,respectively),3-MPA +Glu group (12 μg Glu injection after glutamate decarboxylase inhibitor 3-MPA injection into cerebellar FN),Bic + Glu group (12 μg Glu injection into cerebellar FN after GABAAreceptor blocker Bic injection into lateral hypothalamic area). Pain threshold,abdominal withdrawal reflex (AWR)score and abdominal external oblique muscle electromyography (EMG)were used to detect visceral sensitivity,and malondialdehyde (MDA)content and superoxide dismutase (SOD)activity were measured. Results:Chronic visceral hypersensitivity rat model was successfully established. Compared with CRD group,pain threshold was significantly increased (P＜0. 05),AWR score,EMG amplitude,MDA content were significantly decreased (P＜0. 05 ),and SOD activity was significantly increased in a dose-dependent manner in Glu group (P ＜0. 05 ). Compared with 12 μg Glu group,pain threshold was significantly decreased (P＜0. 05),AWR score,EMG amplitude, MDA content were significantly increased (P ＜0. 05),and SOD activity was significantly decreased in 3-MPA +Glu group,Bic+Glu group (P＜0. 05). Conclusions:Glu injection into cerebellar FN can significantly reduce the visceral sensitivity in rats. The mechanism may be that Glu in cerebellar FN produces GABA via glutamate decarboxylase,and then binding GABAAreceptor in lateral hypothalamic area,resulting in increased intestinal mucosal antioxidant capacity, thereby reducing visceral hypersensitivity.

Cerebellar Control of Saccades / 대한임상신경생리학회지

Saccades are rapid eye movements that shift the line of sight between successive points of fixation. The cerebellum calibrates saccadic amplitude (dorsal vermis and fastigial nucleus) and the saccadic pulse-step match (flocculus) for optimal visuo-ocular motor behavior. Based on electrophysiology and the pharmacological inactivation studies, early activity in one fastigial nucleus could be important for accelerating the eyes at the beginning of a saccade, and the later activity in the other fastigial nucleus could be critical for stopping the eye on target, which is controlled by inhibitory projection from the dorsal vermis. The cerebellum could monitor a corollary discharge of the saccadic command and terminate the eye movement when it is calculated to be on target. The fastigial nucleus and dorsal vermis also participate in the adaptive control of saccadic accuracy.

Expression of the orexinergic system in ischemic cerebral injury and the modulation of the cerebellar fastigial nucleus through electrical stimulation / 中华物理医学与康复杂志

Objective To investigate changes in the expression of prepro-orexin and orexin receptor-1 ( OX1R) following permanent middle cerebral artery occlusion ( MCAO ) with or without preconditioning through electrical stimulation of the cerebellar fastigial nucleus (FNS). Methods Wistar rats were subjected to permanent MCAO and randomly divided into 5 groups: a sham-operated control group (PO), an FNS preconditioning + shamoperated control group (FNS-PO) , an ischemia group, an FNS preconditioning + ischemia group (FNS-PI) and a cerebellar fastigial nucleus injury + FNS preconditioning + ischemia group (FNL-FNS-PI). Each group was divided into 5 subgroups according to the time at which the animals were sacrificed after the MCAO ( 1, 3, 6, 12 and 24 h).RT-PCR was used to detect expression of OX1R mRNA, and ELISA to measure the levels of orexin-A in the hypothalamus and plasma. Results The immunoreactivity of prepro-orexin decreased significantly in the PI groups, with further decreases over time. At the 12th h after MCAO, the immunoreactivity of prepro-orexin reached a minimum.There were significant differences between the rats in the PO and FNS-PO groups. On the contrary, the immunoreactivity of OX1R increased significantly in the PI groups, with further increases continuing over time, peaking at 12 h after the MCAO. There were significant differences between the PO and FNS-PO groups. In the rats with FNS preconditioning (PI-FNS) , the decrease in prepro-orexin and the increase in OX1R were significantly inhibited compared to the PI subgroups at the 6th and 12th hour. There was no significant difference between the FNL-PIFNS group and the PI group. The expression of OX1R mRNA increased significantly in the PI group, with further increases continuing over time, peaking at 24 hours. The plasma levels of orexin-A were not significantly different among the groups, but the levels of orexin-A in the hypothalamus decreased significantly in the PI and FNL-PI-FNS groups, with further decreases continuing over time. At the 12th h after the MCAO the levels were significantly different compared with the PO and PO-FNS groups. While in the rats with FNS preconditioning (PI-FNS) , the decrease in orexin-A level was reversed and there was no significant difference compared with PO and PO-FNS groups. Conclusions The orexinergic system is altered following cerebral ischaemia. FNS preconditioning may be able to regulate these changes.

Advance in Research on Brain Protection Mechanisms of Fastigial Nucleus Stimulation (review) / 中国康复理论与实践

@#The research on fastigial nucleus could be traced back to 19th century. However the great achievements on cerebrum overshadowed the importance of cerebellum and its nucleus. In recent 30 years, with the finding of brain protection effect of fastigial nucleus stimulation, much attention has been given to this field. Now its widely accepted that electrical stimulation of fastigial nucleus has brain protection effect and concrete mechanisms can be concluded as: improving the electrical instability around the infarct zone, reducing peri-infarction depolarizing wave and cortical spreading depression; suppressing microvessels inflammatory reaction; inhibiting cell apoptosis; reducing the neurons damage and facilitates neovascularization and so on. These new discoveries was reviewed and further expectation on this field was put forward by the authors.
