まとめ
脳脊髄液 (CSF) のペニシリン濃度は,神経シフィリス患者で測定されました. 静脈注入ペニシリンGは検知可能なCSFレベルを達成したが,筋肉内ベンザチンペニシリンGはめったに達成できず,潜在的な治療課題を示唆している.
科学分野:
- 感染症 感染症は感染症です.

主な方法:
- 研究には,ニューロシフィリスとCSF胞症が確認された15人の患者が含まれていました.
- 2人の患者は4週間,静脈内ペニシリンG (5~1000万単位/日) を投与された.
- 13人の患者は,筋肉内ベンザチンペニシリンG (3.6百万単位/週) を4週間投与された.
- ペニシリン濃度測定のための治療中に,またはその後に,腰椎穿刺によってCSFのサンプルを採取した.
主要な成果:
- 静脈注射ペニシリンGを受けた2人の患者の1人は,CSFで0.3mcg/mlのペニシリンを持っていた;もう1人は2.4mcg/mlを持っていた.
- 筋肉内ベンザチンペニシリンGを投与した13人の患者のうち12人は,CSFで検知できないペニシリン濃度を示した.
- 筋内ベンザチンペニシリンGを投与した1人の患者は,CSFで0.1mcg/mlのペニシリンを検出した.
結論:
- 静脈注射ペニシリンGは,神経シフィリスの患者で,筋内ベンザチンペニシリンGと比較して,CSFへのよりよい浸透性を示した.

Overview
Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain.

Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
