The effect of vasodilatation as obtained by lumbar sympathectomy on the growth of bones in normal young animals
The effect of changes in the circulation of blood on the metabolism of bone in general is well known to surgeons. The bones adjacent to an acute inflammatory process may share in the regional hyperaemis and undergo considerable osteoporosis. One of the most notable examples of this process has been …

Sympathetic Innervation of the Rat Adrenal Cortex and Its Effects on the Compensatory Adrenal Cortical Growth Response to Unilateral Adrenalectomy (Catecholamine, Endocrine, Splanchnic Nerve, Cell Proliferation)
… This innervation was eliminated after neonatal sympathectomy with guanethidine or 6-hydroxydopamine, but unaffected by splanchnic nerve ligation or suprarental ganglion extirpation. Sympathetic innervation was shown to mediate compensatory adrenal cortical growth, a cell proliferation response …

Audit of acute limb ischaemia in a paediatric intensive care unit
… received various forms of pharmacological sympathectomy, in addition to conservative therapy. One patient had missing data on the type of sympathectomy that was done. The response to the sympathectomies was: 60.9% good, 8.7% moderate, 8.7% poor and in 21.7% no responses. Documented tissue …

Refining Our Understanding of the Hematopoietic Stem Cell Niche
… itself, or systemic effects of general sympathectomy. To test this, I developed a model for bone marrow-specific neuropathy by conditionally deleting nerve growth factor (Ngf) from bone marrow stromal cells. Using this model, I analyzed the role of bone marrow peripheral nerves in …

Prophylactic Ondansetron Administration to Attentuate Spinal Anesthesia-Induced Hypotension in Cesarean Section
… suppression of the sympathetic nervous system (sympathectomy) and activation of the Bezold-Jarisch Reflex (BJR). The BJR activation exacerbates hypotension and can lead to asystole and cardiovascular collapse. Studies have shown that 5-hydroxytryptamine subtype 3 (5- HT3) receptor antagonists …

Identifikation von potentiell prädiktiven biochemischen Faktoren für den Erfolg der renalen Denervation bei therapierefraktärer Hypertonie und ihre Veränderung nach Intervention
Hintergrund: Die renale Denervation gilt als ein sicheres Verfahren zur Behandlung von therapieresistenter Hypertonie, es ist jedoch noch nicht hinreichend erklärt, welche Faktoren zu einer unzureichenden Blutdrucksenkung nach der renalen Denervation führen und welchen Einfluss das Verfahren auf …
