Objective To investigate the postmortem redistribution of Avermectin in acute poisoning death of rabitts. Methods According to the minimum lethal dose intragastric of 250mg/kg avermectin, the avermectin contents in the heart blood and major organs and tissues of the rabitts after death of 0h~72h were assayed by HPLC method. Results Determination of clinical death time was 120.6±9.2min(x±s, n=10)by intragastric 250mg/kg avermectin to the rabitts; Lethal blood concentrations and lethal tissue concentrations of Avermectin were determined; Presence of postmortem redistribution of avermectin contents in the heart blood and major organs and tissues of the rabitts after death of 0h~72h were proved; Determination of the liver, kidney and lung were the best tissue samples for toxicological anaysis. Conclusion The data of Avermectin postmortem redistribution in the rabbits have important reference value for the forensic management of such cases.

Objective To evaluate the role of spinal extracellular signal-regulated kinase (ERK) signaling pathway in reduction of remifentanil-induced hyperalgesia by electro-acupuncture (EA) at Zusanli in rats with incisional pain.Methods Fifty male adult Sprague-Dawley rats, weighing 250-280 g, in which the intrathecal catheter was successfully placed without complications, were randomly divided into 5 groups (n=10 each) using a random number table: control group (group C), remifentanil + incisional pain group (group RI), EA at acupoint group (group E) , EA at non-acupoint group (group NE), and 1/2 ERK inhibitor U0126 + EA at acupoint group (group UE).Normal saline 0.1 ml · kg-1 · min-1 was infused intravenously for 60 min in group C.In RI, E, NE and UE groups, after the model of incisional pain was established, remifentanil 1.0 μg · kg-1 · min-1 was infused for 60 min, and in addition, EA (intensity 10 mA, frequency 4 Hz) of Zusanli lasting for 60 min was performed at the same time in E and UE groups, and EA was performed at the points 5 mm lateral to the acupoints of Zusanli on the operated side simultaneously in group NE.ERK1/2 inhibitor U0126 5 μg (in 5％ dimethyl sulfoxide 10 μl) was injected intrathecally in group UE, and 5％ dimethyl sulfoxide 10 μl was injected intrathecally in the other groups.The mechanical paw withdrawal threshold (MWT) was measured before remifentanil or normal saline infusion (T1) , and at 2 h, 1, and 2 days after the end of infusion (T2-4).After MWT was measured at T4, the expression of ERK1/2 and phosphorylated ERK1/2 (p-ERK1/2) in spinal cord dorsal horns was measured by Western blot.Results Compared with group C, the MWT was significantly decreased at T2-4 in RI, E, NE and UE groups, and the expression of p-ERK1/2 was up-regulated in RI, E and NE groups (P＜0.05).Compared with group RI, the MWT was significantly increased at T2-4 , and the expression of p-ERK1/2 was down-regulated in E and UE groups (P＜0.05);and no significant change was found in the parameters mentioned above in group NE (P＞0.05).Compared with group E, the MWT was significantly increased at T2-4, and the expression of p-ERK 1/2 was down-regulated in group UE (P＜0.05).Conclusion The mechaism by which EA at Zusanli reduces hyperalgesia induced by remifentanil in rats with incisional pain is related to inhibited activation of ERK signaling pathway in the spinal cord.
