Objective To investigate the effects of intravenous injection of α-crystallin on retinal ganglion cells (RGC) and some important organs of the Long Evans rats. Methods RGC were retrogradelabeled by fluorogold through bilateral superior colliculus and lateral geniculate body for seven days before optic nerve crush injury. Twenty-three Long Evans rats were used for this study, including three rats of normal control group and 20 rats of experimental group. Twenty rats were randomly divided into saline control group and three α-crystallin injection groups, which received tail vein injection of 1.25 ml isotonic saline and three different concentrations (1 × 10-2 , 1 × 10-1 and 1 g/L) of α-crystallin respectively, once every two days and totally seven times. After two weeks, the labeled RGC were counted, and the pathological changes on liver, kidney, brain, spleen and the lungs were investigated. Results Compared with the normal control group, although the number of RGC markedly decreased after two weeks of optic nerve crush injury in every group, the number of RGC in α-crystallin-treated groups was more than those in the saline control group. There were 2074± 150 RGC per mm2 in normal control group, 85 ± 15 RGC per mm2 in saline control group, 124±26 RGC per mm2 in 1 × 10-2 g/L α-crystallin group, 128± 31 RGC per mm2 in 1 × 10-1 g/L α-crystallin group, 164 ± 20 RGC per mm2 in 1 g/L α-crystallin group (F= 18. 660,P＜0. 01). No congestion, swelling, inflammation and other pathological changes were found in liver,kidney, brain, spleen and lung. Conclusions Intravenous injection of α-crystallin protein has protective effects on RGC after the optic nerve crush injury, and no significant effects on important organs.

Objective:To evaluate the predictive value of 3 methods, namely plasma paraquat concentration, severity index of paraquat poisoning (SIPP), and acute physiology and chronic health evaluation (APACHE II) in severity evaluation and prognosis of acute paraquat poisoning. Methods:A total of 73 acute paraquat poisoning patients with oral administration were collected. Paraquat concentration in the plasma and other parameters on admission for SIPP and APACHE II were taken from medical records. According to the clinical outcome in the hospital or 7 days atfer the discharge, discrimination and calibration test were performed to evaluate the prognosis of the 3 methods. Results:Discrimination of the 3 methods was greater than 0.8, and the area under the receiver operator curve for SIPP (0.938) was greater than paraquat concentration in the plasma (0.857) and APACHE II (0.801) with statistical signiifcance (z=2.429, 2.021;P=0.015, 0.043). Difference in plasma paraquat concentration (0.857) and APACHE II (0.801) had no statistical signiifcance (z=0.755, P=0.450). Hosmer-Lemeshow good fit test suggested better calibration value with statistical signiifcance for the 3 methods (P>0.05). Conclusion:hTe 3 methods are valid in the severity evaluation and prognosis of acute paraquat poisoning. SIPP is the most preferred method, followed by paraquat concentration on admission. When there is no facility to measure paraqut concentration, APACHE II can be used as a reference for the death risk in acute paraquat poisoning.
