视网膜的

When light falls on a receptor it sends a proportional response synaptically to

视网膜含有可以感受光的视杆细胞和视锥细胞。这些细胞将它们感受到的光转化为神经信号。

It appears that glutamatergic and cholinergic inputs from the retina, and cholinergic and gabaergic inputs from NI may converge on tectal neurons in anurans.

因比，从视网膜来的谷氨酸能、胆碱能输入和从峡核来的胆碱能、GABA能输入共存于顶盖神经元。

Retinotopic inputs to the optic tectum hae been thoroughly mapped, but now Sato et al. map tectal efferents that project to the premotor reticulospinal system of the hindbrain.

视网膜区域定位输入信号到视顶盖已经得到了充分的定位，现在Sato等人绘制了覆盖层传出神经，它们投射到后脑的网状脊髓系统。

Results:① Neuroglobin-immunocreactive positive cells were detected in cortex, thalamencephalon, hippocampus, hypothalamus, cerebellum, brain stem and spinal cord;② Ngb-IR positive nerve cells were also detected in peripheral nervous system such as intramural ganglia, myelinated nerve fiber and retina;?Substantial Ngb protein expression was also found in metabolically active endocrine tissues such as the pituitary gland , adrenal gland and testis.?

结果：(1)在所观察的大脑皮质、海马、丘脑、下丘脑、脑干、小脑和脊髓神经细胞都出现Ngb蛋白免疫阳性反应，不同区域表达强度不同：(2)在外周神经系统的神经节、有髓神经纤维和视网膜也观察到Ngb免疫阳性反应；(3)垂体、肾上腺、睾丸也可见到Ngb-IR阳性细胞。

Http://www.44dx.com objectiveto investigate the therapeutic effects of subconjunctival verapamil on outcome in an experimental model of traumatic proliferative vitreoretinopathy.methodsan experimental model of traumatic proliferative vitreoretinopathy was induced in pigment rabbits,which then were selected randomly to receive either subconjunctival verapamil injection treatment or a placebo injectiondaily for 3 weeks.animals were examined by indirect ophthalmoscopy at weekly intervals for 5 weeks.eyes were enucleated for light microscopy 5 weeks later.resultsfifty-six percent(18 of 32)of the rabbits receiving subconjunctival verapamil injection had developed tractional retinal detachment,whereas eighty-one percent(26 of 32)of control animals had developed tractional retinal detachment(χ2=4.655,p=0.031).the results of clinical examination and light microscopy didn?

http：//www.44dx.com 目的观察维拉帕米(verapamil，ver)对眼后节穿通伤增生性玻璃体视网膜病变(proliferative vitreoretinopathy，pvr)的影响。方法64只青紫蓝兔，每只兔任选其中一只眼制备外伤性pvr模型后随机分为两组，治疗组在模型制备后立即每日结膜下注射2.5 mg/ml的ver0.5ml，对照组则每日结膜下注射生理盐水0.5ml，共21天。模型制备后7天内每天用裂隙灯显微镜及间接立体检眼镜观察伤口、角膜、前房及眼底情况，此后每周第3，7天各检查1次。伤后第35天时常规摘除模型制备眼作光镜观察。

JAK-STAT signal transduction pathway was involved in the pathological processes in the retinal after transection of the optic nerve.

Janus激酶-信号转导子与转录激活子信号转导途径可能通过STAT3蛋白的活化，参与视神经切断后视网膜内的病理改变过程。

RESULTS: Unmedicated and medicated depressed patients displayed dramatically lower retinal contrast gain.

结果：未服药治疗和已服药治疗的抑郁患者获得的视网膜反差显著减少。

Methods 126 cases (252 eyes) enrolled by diagnosis standard were given 4+1 treatment (the treatment with vasodilating agent,neurotrophic agent,Chinese medicine and acupuncture as the main treatment and carbogen inhale as the adjuvant one).

方法选择符合诊断及入选标准的RP患者126例252眼，采用4+1疗法综合治疗，即用血管扩张剂、神经营养剂、中药、针灸治疗的同时，辅以卡波金吸入。26~38个月后观察患者全身和眼部症状、视力、视野、视网膜电图、血氧分压及血流情况。

Both healthy rabbits and rabbits with glass implanted in their vitreum were involved.

作者应用气相色谱法测定健康兔和眼球内埋玻璃块的兔视网膜脂质中脂肪酸的组成和含量。

Objective: To compare the levels of transforming growth factor β2 (TGF-β2) in the vitreum of patients with proliferative diabetic retinopathyand normal subjects and to evaluate the role of TGF-β2 in the pathological course of PDR.

目的：通过对增殖性糖尿病视网膜病变(proliferative diabetic retinopathy， PDR)患者玻璃体中转化生长因子β2(TGF-β2)含量的研究，探讨TGF-β2在PDR病理过程中的作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
