The CACNA1F gene encodes a member of the alpha-1F subunit family in the voltage-dependent calcium channel (Cav1.4) complex. Mutations in this gene result in incomplete congenital stationary night blindness (iCSNB2) in humans. And Cav1.4 mutation could affect the functions of the skeletal muscle. This study investigated the role of Cacna1f mutations...

Due to the lack of an appropriate animal model, few studies have addressed the integration of visual and vestibular information in the visual system. Using a mouse model with a visual defect (retinal degeneration fast, rdf), we have verified that the prepositus hypoglossal nucleus (PrH) and the Kooy cap of the inferior olive medial nucleus (IOK) ar...

Oxidative reactions are thought to be a major cause of light-induced retinal degeneration. This study was designed to investigate the effects of hydrogen-rich saline (HRS) on the prevention and treatment of light-induced retinal injury in rats. Male Sprague--Dawley rats were divided randomly into three groups: light damage, HRS prevention (5 ml/kg,...

This experiment was designed to determine whether hydrogen (H(2)) rich saline can ameliorate brain abnormalities in a rat model with acute carbon monoxide (CO) poisoning. Sprague-Dawley male rats were used for CO poisoning and H(2) rich saline treatment. Changes in neurons, microglias, and myelin sheath were observed by electron microscope. Neuron...

Motion sickness presents a challenge due to its high incidence and unknown pathogenesis although it is a known fact that a functioning vestibular system is essential for the perception of motion sickness. Recent studies show that the efferent vestibular neurons contain calcitonin gene-related peptide (CGRP). It is a possibility that the CGRP immuno...

Background: Studies have shown that inhalation of hydrogen gas, which acts as an antioxidant, can protect the brain against free radicals in rats with ischemia-reperfusion. The neuronal damage caused by acute carbon monoxide (CO) poisoning is partly free radical mediated. We hypothesize that hydrogen may prevent neurological damage from CO poisoni...

Cacna1f gene mutation could lead to incomplete congenital stationary night blindness (iCSNB) disease. The CSNB-like phenotype rat is a spontaneous rat model caused by Cacna1f gene mutation. The present study explored the phenotypic properties of behavior performance in CSNB rats further. The vision-related behaviors of CSNB rats were assessed with...

Oxidative stress is associated with insulin resistance (IR) and is thought to contribute to the development and progression toward type 2 diabetes (T2DM). This study was undertaken to isolate the bioactive polysaccharide (SMPW1) from Salvia miltiorrhiza Bunge and investigated its protective effects on IR model in rats induced by tert-butyl hydroper...

This work was conducted to determine whether congenital stationary night blindness (CSNB), which is caused by a Cacna1f mutation, could affect development of second-order neurons in the retina, such as horizontal cells (HCs). The CSNB rats and age-matched wild type rats were sacrificed at postnatal days (PND) 15, 30 and 60. Morphometric analyses of...

Purpose. To describe the characteristics of rod and cone functions in rat models for congenital stationary night blindness (CSNB) and retinal cone dysfunction (RCD). Methods. Rod and cone function were isolated by recording the rod-/cone-driven flicker and blue light flicker electroretinograms (ERGs). Results. During dark adaptation, the amplitudes...

The disease-causing gene which underlies a naturally occurring X-linked mutant cone dysfunction Sprague-Dawley rat model was investigated. Full-field electroretinogram (ERG) and simple sequence length polymorphism analyses were applied to 441-second filial generation rats that were derived from crossing a mutant rat and a Brown-Norway rat. After id...

Myopic eyes show structural differences from normal eyes and may respond differently to microgravity, increasing the risk for possible development of ocular hypertension and glaucoma on orbit. In this experiment we used head-down rest (HDR) at an angle of 15 degrees to produce hydrostatic changes similar to acute exposure to microgravity. There wer...

To identify the gene mutation responsible for a previously described rat model of X-linked congenital stationary night blindness (CSNB). Rat orthologous genes for Nyx and Cacna1f were isolated from retina through rapid amplification the cDNA ends (RACE) and examined for mutations. Electroretinograms were used to identify affected animals. The rat N...

To describe a possible spontaneous rat model of X-linked congenital stationary night blindness (CSNB). Experimental animals were generated by mating the affected animal to normal rats, and from interbreeding littermates. To define the inheritance pattern, full-field electroretinograms (ERGs) were recorded from all progeny. During the course of othe...
