Chinese Journal of Experimental Ophthalmology 2012;30(2):101-105
BackgroundWith the number of diabetics increases,people pay more attention to the diabetic keratopathy.The major mechanism leading to diabetic keratopathy is diabetic corneal neuropathy.So it is significant to observe pathologic mechanism of diabetic corneal neuropathy. Objective To investigate the protective effects of edaravone( a free radical scavenger) on corneal nerve of rats with experimental diabetic corneal neuropathy,then explain the effects of oxidative stress in the pathologic mechanism of diabetic corneal neuropathy. Methods Seventy Sprague-Daxley male rats were taken as experimental subjects and 20 of them were used as normal control group.The remaining 50 were induced to be diabetic mellitus by a single intraperitoneal injection of streptozotocin and divided into 2 groups randomly:edaravone treated group and diabetic control group.In the edaravone treated group,edaravone(0.2 g/L) eye drops were used 3 times a day until the animal was killed.Five rats in each group were sacrificed at 6,8,10 and 12 weeks respectively.Then the corneal sensation,number of corneal nerve fibers,morphology,content of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) in the corneal tissue were detected.ResultsIn the diabetic control group,the corneal sensation and the number of corneal nerve fibers were decreased,the density of neural network for cluster was sparse,the nerve activity was decreased,the content of MDA in the corneal tissue was significantly increased,the activity of SOD in the corneal tissue was significantly decreased (P<0.01 ).Accompany with the course of disease,the above change was obvious day after day.Compared with the diabetic control group,the corneal sensation and the morphological abnormalities in corneal nerve of edaravone group were improved significantly which had the partial branches to the 12th week,the content of MDA in the corneal tissue was significantly decreased,the activity of SOD in the corneal tissue was significantly increased (P<0.01).Conclusions Edaravone can lower diabetic corneal nerve of rats with experimental diabetic corneal neuropathyinjury,Oxidative stress may be a critical pathologic mechanism of diabetic corneal neuropathy.

OBJECTIVE: To explore whether there are beta-amyloid protein (Abeta) binding elements in heart-beneficial recipe (HBR, a compound traditional Chinese herbal medicine), which can ameliorate the cytotoxicity of Abeta. METHODS: The extract of HBR and Abeta(1-40) were co-precipitated, and the Abeta(1-40) in pellets was detected by immunoblotting. Affi-gel-Abeta(1-40) was constructed, and Affi-gel-Abeta(1-40) affinity elements from the extract of HBR were analyzed by high-performance liquid chromatography (HPLC). The assay of lactic dehydrogenase (LDH) release from the primary cultured rat cortex neurons was used to evaluate the cytotoxicity of Abeta(1-42), and the protection effects of the HBR serum and the Affi-gel-Abeta(1-40) treated HBR serum. RESULTS: Immunoblotting examination showed Abeta(1-40) could be co-precipitated with components of HBR following co-incubation, and the amount of Abeta(1-40) within pellets decreased when the HBR extract was diluted. Abeta(1-40) affinity elements from the extract of HBR, eluted from Affi-gel-Abeta(1-40) by glycine solution (pH=2.5), could be detected by HPLC-fluorescent detector system. The analysis of LDH release showed that exposure of neurons to 5 micromol/L Abeta(1-42) for 48 h caused a significant increase of LDH release in either a serum free or 10% serum contained culture condition (P<0.01). The rat HBR serum was able to suppress Abeta(1-42) induced LDH release (P<0.05), whereas Affi-gel-Abeta(1-40) treated HBR serum still maintained the ability to attenuate Abeta(1-42) induced LDH release although the effect was somewhat decreased compared with Affi-gel treated HBR serum. CONCLUSION: There are Abeta affinity components in HBR, which could not increase the Abeta cytotoxicity, but might be able to inhibit the cytotoxicity of Abeta. The results implied that the exploration of Abeta affinity elements from Chinese medicinal recipe which is effective for Alzheimer disease, might be an important direction in Alzheimer disease therapeutic research area.

Objective To compare the anthelmintic effect of albendazole with that of triclabendazole against Fasciola giganti-ca. Methods Two patients infected with Fasciola gigantica were investigated,and one was administered with albendazole orally (200 mg,twice per day for 5 days)and another was administered with triclabendazole[10 mg/(kg?d)for 2 days]. Their total fe-ces were collected daily during the period of whole therapy,and the eggs of the parasite were collected by using the nylon bag method,and incubated at 28℃. Results The parasite eggs were detected from the first patient’s dejecta on the 1st,2nd and 5th day after the end of the treatment,and no miracidiums hatched out as well as no eggs developed during the period of 25 days of the incubation. Meanwhile,her body temperature fluctuated between 37.4℃and 38.3℃,and she still complained bellyache. For the other invalid,the eggs were not detected on the 2nd and 5th day after the end of the treatment. However,the eggs before and dur-ing the treatment developed the miracidiums of Fasciola gigantica on the 13th day after the incubation,but the eggs collected from the 1st day after the termination of the therapy did not develop and no miracidiums hatched out. At the same time,the signs and symptoms of the patient vanished after the 4th day of the end of the therapy. Conclusions Albendazole has no obvious insecticid-al activity on adult Fasciola gigantica in the short term,but may affect the development of eggs. Triclabendazole has the anthelmin-tic effect on the adults as well as eggs of Fasciola gigantica. In addition,triclabendazole has the characteristics of well curative ef-fect,short course of treatment,and no obvious side effects.
