Electro-oculogram of Retinal Vein Occlusion

Twenty five cases, including 26 eyes with retinal vein occlusion (RVO) were examined by means of the electro-oculogram. The results showed that 23 of the 26 eyes suffering from RVO exhibited abnormalities of the electro-oculogram (EOG). The potential difference and Arden ratio in the RVO eyes were lower than those in the normal eyes (P<0.01). The more the visual acuity of ill eyes was decreased, the higher the abnormal rate of EOG in ill eyes was. 14 eyes had the visual acuity less than 0.1, whose EOGs were abnortmal. Six eyes had the visual acuity from 0. 2 to 0. 4, in which the EOGs of 5 eyes were abnormal. Six eyes had the visual acuity more than 0. 5, a-mong which the EOGs of 4 eyes were abnormal. Based on the above observations, it may be considered that the circulatory disturbance resulting from RVO damages not only the internal layer but also the external layer of the retina. We suggest that EOG is a useful method for distingquishing lesions caused by RVO and may reflect the functional condition

REGULATING FUNCTION OF COENZYMIZATION AND DECOENZYMIZATION OF THE LACTATE DEHYDROGENASE ISOZYMES IN THE MOUSE TISSUES DURING HYPOXIA

Objective. To study the characteristics of changes of LDH enzyme patterns of mice under slight hypoxia.Methods. Mice treated with artificial hypoxia, various tissues were made for the test of LDH enzymatic activity by the specific staining technique. LDH (1 -5) relative percentage enzymatic activity (RPEA) were measured with CS-910 dual-wavelength thin layer chromatography scanner.Results. The RPEA of LDH isozymes of various tissues after slight hypoxia shifted to the isozymes LDH1 and LDH2, whose principal subunits are H subunits, and the RPEA of LDH,(H4), LDH2(H3M) increased, while RPEA of LDH5(M4) in various tissues decreased prominently except the cardiac muscle, and that of LDH4(HM3) decreased as well. After polyacrylamide gel electrophoresis (PAGE) of the hypoxia treated cardiac muscle specimen was made, activity subbands originated regularly in the isozyme patterns of LDH, with the regularity of LDH1 (0 subband), LDH2 (0-1 subbands), LDH3 (0-2 subbands), LDH4 (1-3 subbands), LDH5 (2-4 subbands).

丙型肝炎病毒感染对肾移植术后影响的临床研究

OBJECTIVE: To study the influence of hepatitis C virus (HCV) infection on the clinical outcome of kidney transplantation. METHODS: The recipient/graft survival, the incidence of acute/chronic rejection and cause of death in 86 HCV-infected recipients of renal transplantation were compared with those in another 86 recipients without HCV infection. RESULTS: HCV-infected recipients had significantly shorter 5-year survival (74.4%) than those without HCV infection (87.2%, P<0.01). The 1-year (94.2%/90.7% vs 96.8%/96.0%) and 3-year recipient/graft survival rates (88.4%/79.1% vs 90.7%/87.2%), the incidence of acute/chronic rejection (31.3% vs 21.2%, and 12.5% vs 6.5%) and the 5-year graft survival (73.3%/81.4%) were comparable between the two groups (P>0.05). Hepatic disease was identified as the primary cause of mortality. CONCLUSIONS: HCV infection may affect the long-term survival of the recipients with kidney transplantation, and therefore should be considered as a relative contraindication of kidney transplantation.
