概括

这项研究绘制了大鼠的功能性勃起神经图,只发现了一小部分表达P-nNOS (酸化神经氧化合成酶). 这项研究旨在通过识别性功能关键神经来改善神经节约性前列腺切除术的结果.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
神经科学是一个神经科学.
手术解剖学手术解剖学

背景情况:

由于复杂的解剖学和患者变异,在急性前列腺切除术 (RP) 期间保护勃起性神经具有挑战性.
勃起涉及特定的洞穴神经 (CNs),这些神经神经氧化合成酶 (nNOS) 在Ser-1412中酸化,以应对性刺激.

研究的目的:

在前列腺周区域绘制功能性勃起相关 (含[P-nNOS]) 神经的分布和数量.
为了在整体CN分布中区分这些功能神经.
调查对方CN之间潜在的功能通信.

主要方法:

在大鼠中电刺激CNs以诱导阴茎勃起和nNOS酸化在Ser-1412.
使用TuJ1 (泛轴标记物) 和P-nNOS或总nNOS抗体对前列腺组织进行全双染.
修改的光学清除和显微镜检查用于神经可视化和量化.

主要成果:

在老鼠前列腺周围区域生成了含有P-nNOS的神经的详细地图,这对勃起至关重要.
功能性勃起性神经仅占所有前列腺周神经的17.5%,占所有含有nNOS的神经的28.4%.
在相反的CN之间没有发现功能性内化.

结论:

通过P-nNOS (Ser-1412) 表达物识别的周围前列腺神经纤维的独特子集代表了功能性勃起性神经.
这项基础研究预计将增强神经节约的RP技术,并改善人类手术后的性功能.
需要使用更大的样本大小进行进一步的研究来验证这些发现.

关键词:

这是神经纤维神经纤维.神经元中的一氧化合成酶.这是光学成像.阴茎勃起勃起的阴茎这是前列腺切除术.

Male Sexual Response: Erection & Ejaculation

Male Sexual Response: Erection & Ejaculation

Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Accessory Glands of the Male Reproductive System

Accessory Glands of the Male Reproductive System

The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...
