ABSTRACT
Objective To explore the treatment mechanism of safflower injection on sudden deafness through the changes of the hearing threshold, serum superoxide dismntase (SOD) and malonyldialdehyde (MDA) before and after treatment. Methods 40 cases of sudden deafness were divided into two groups: groupⅠ(group with safflower) and groupⅡ (group without safflower). The concentrations of serum MDA and SOD and hearing threshold were detected before and after treatment. 25 cases of normal hearing as the control group. Results (1) The total efficiency in the group Ⅰwas higher than the group Ⅱ (P0.05). Conclusion Safflower injection could scavenge oxygen free radical and improve the quality of hearing recovery.
ABSTRACT
Objective To explore the value of SOD activity in diagnosis of central nervous system leukemia (CNSL )by detec-ting SOD activity of cerebrospinal fluid of patients with CNSL .Methods The cerebrospinal fluid of 55 patients from department of hematology of Nanfang hospital of southern medical university were collected from January 2008 to January 2009 ,in which 30 pa-tients suffered with central nervous system leukemia (CNSL group) ,the other 25 patients suffered with acute leucemia without im-paired central nervous system(control group) .The SOD activity of cerebrospinal fluid was detected by the xanthine oxidase meth-od ,while the routine test ,biochemistry test and cell smear of cerebrospinal fluid was detected .Results There were statistics differ-ence in the level of white cell and protein in cerebrospinal fluid between CNSL and control group (P0 .05) .There was statistics difference in the level of SOD activity between CNSL and control group(P<0 .05) .The white cell quantity and the protein level in cerebrospinal fluid had negative corre-lation with the activity of SOD ,(r=0 .871 ,P=0 .000 ;r=0 .518 ,P=0 .003) .The activity of SOD in the cerebrospinal fluid had sta-tistics difference before and after intrathecal chemotherapy (P<0 .05) .The activity of SOD in the cerebrospinal fluid whose under 45 year-old (755 .64 ± 345 .77) ,which was significant lower than that of the paitents whose equal with or above 45 year-old (1 420 .49 ± 307 .69)(P<0 .05) .Conclusion The changes of the SOD activity in the cerebrospinal fluid had relation with central nervous system leukemia ,and the SOD activity might be a auxiliary diagnosis index used in central nervous system leukemia by revi-sing age factor .
