Comparison of decompressive surgery, electroacupuncture, and decompressive surgery followed by electroacupuncture for the treatment of dogs with intervertebral disk disease with long-standing severe neurologic deficits. Journal of the American Veterinary Medical Association 2010; 36(11):1225-9

Joaquim JG et al. JAVMA 2010

Joaquim JG, et al. JAVMA 236, 1225-1229 June 2010. n  Evaluated 40 dogs with clinical signs of IVDD >48 hours n  All dogs evaluated were a Grade 4/5 n  Re-evaluated after treatment in 6 months n  Deemed a success if Grade decreased to 1 or 2

n  Return to ambulation

n Success of Treatment groups: n EAP: 15/19 dogs (79%) n Decompressive surgery alone: 4/10 dogs (40%) n EAP and Decompressive surgery: 8/11 dogs (72%) Clinical success when initial grade 4 or 5 was

classified as grade 1 or 2 within 6 months after the end of treatment

Results: �  Recovery rate (Grade 4 or 5 becoming Grade 1-2 within 6 months) was

significantly higher for dogs treated with EA alone (15/19 or 78.9%) and EA plus surgery (8/11 or 72.7%) than for dogs that only had surgery (4/10 or 40%).

�  The investigators concluded that if early surgical intervention (within 24 hours) was not possible, dogs with Grade 4 or 5 neurological deficits may benefit from tapering doses of prednisone and EA.

n  EAP was more effective than DSX for recovery of ambulation and improvement in neurologic deficits in dogs with long-standing severe deficits attributable to thoracolumbar IVDD

n  If early surgical intervention (within 24 hours) was not possible, dogs with Grade 4 or 5 neurological deficits may benefit from tapering doses of prednisone and EA

40% 78.9% 72.7%

If early DSX was not possible, dogs with Grade 4/5 may benefit from tapering doses of Pred and EA

•  12 mice induced sepsis/endotoxemia

–  ê TNF, MCP1, IL6, INF-ϒ

–  ê Fever

–  é Dopamine (4X)

•  Mediated via vagal modulation

•  Control inflammation Septic shock, sepsis, endotoxemia, colitis, pancreatitis

Rafael Torres-Rosas, 2014

Survival was recorded for three weeks and no late deaths were observed,

Given that the vagus nerve inhibits cytokine production in the spleen11,26, and prevents systemic inflammation in endotoxemia

Electroacupuncture controls systemic inflammation in sepsis via the sciatic, the vagus nerves, and catecholamines from the adrenal glands

ACP is effective for reducing elevated BT, and mediated through the suppression of hypothalamic production of pro-inflammatory cytokines

Electroacupuncture increased the levels of DOPA decarboxylase in the adrenal medulla by 4-fold without significantly affecting the levels of Dopamine beta-hydroxylase (Fig.2e,f). Electroacupuncture activated the neuronal network of the adrenal medulla in the proximity of the chromaffin cells overexpressing DOPA decarboxylase

Control inflammation in infectious & inflammatory disorders

Septic shock, sepsis, endotoxemia, colitis, pancreatitis

Dopamine and norepinephrine have generally been considered first-line agents in patients presenting with septic shock; in fact, recent consensus guidelines and expert recommendations have suggested that either agent may be used as a first-choice vasopressor in patients who have septic shock.[2] Epinephrine, vasopressin, and neosynephrine may be useful second-line agents. Inotropic therapy with dobutamine may also be necessary in myocardial dysfunction. Because hypotension may be life-threatening, vasopressors help to maintain adequate blood flow and tissue perfusion despite hypovolemia.[2] Dopamine increases heart rate and stroke volume, leading to an increase in cardiac output and MAP. In contrast, norepinephrine is a vasoconstrictor and thereby increases MAP with little effect on heart rate and stroke volume. While norepinephrine is considered to be more potent and thereby more effective in increasing blood pressure in septic shock, dopamine may be useful in patients with systolic dysfunction, but is also associated with more tachycardia and dysrhythmias. There is also concern regarding adverse effects on the endocrine and immune systems with dopamine. It has also been noted that norepinephrine may potentially decrease cardiac output, oxygen delivery, and blood flow to vulnerable organs despite adequate perfusion pressure..[4]
