The Effect of Oculo-Acupuncture on Recovery from Ethylene Glycol-Induced Acute Renal Injury in Dogs

Abstract

The potential recovery effect by oculo-acupuncture (OA) on ethylene glycol-induced acute renal injury in dogs was investigated. Acute renal damage was induced by ingestion of ethylene glycol in six mongrel dogs. The dogs were assigned to control (three dogs) and experimental (three dogs) groups. The control group did not receive any treatment, while the experimental group was treated with oculo-acupuncture at kidney/urinary bladder region plus zhong jiao region of the eyes after the induction of renal damage. Serum blood urea nitrogen (BUN), creatinine, sodium (Na), chloride (Cl), and potassium (K) were measured in both control and experimental groups. The blood RBC and Hb were also examined. The serum BUN and creatinine activities in the experimental group were lower than those in the control group, the serum Na and Cl had the irregular change in both groups, and the blood Hb in the control and experimental group showed decreasing tendency. Significant differences were observed on the 3rd and 7th day in BUN, 7th day in creatinine, 2nd day in Na and Cl, and 7th day in Hb when compared to the control group. Whereas, serum K concentration and RBC in the experimental group did not change significantly. The recovery findings of the renal injury were also observed in the experimental group histopathologically. In conclusion, OA therapy (kidney/urinary bladder region plus zhong jiao region) was effective for recovery of the renal injury induced by ethylene glycol in dogs.
