ABSTRACT
Objective To investigate the effect of glutamine (Gln) on the content of reduced glutathione hormone (GSH) and aminoglutaminic acid (Glu) of spinal cord following ischemia-reperfusion injury. Methods Totally 40 healthy adult male rabbits were randomly divided into five groups: sham-operation group (S group), ischemia-reperfusion injury group (I/R group), low-dose glutamine group (L Gln group), median-dose glutamine group (M Gln group) and high-dose glutamine group (H Gln group). After glutamine preconditioning, the model of spinal cord ischemia-reporfasion injury was established according to Zivin's method. The general status of animals was observed and the changes of Jacobs scoring were recorded in each group. Malondialdehydes (MDA), GSH, Glu and superoxide dismutase (SOD) activity in lumbar spinal cord tissues were determined using chemical colorimetry. The neuron number and deviation rate in spinal cord anterior horn were observed histopathologically. Results There was no significant difference between L Gin group and I/R group in behavior scoring, SOD activity, content of MDA and Glu, neuron number and deviation rate of spinal cord (P>0.05); however, there was a significant difference in GSH content of spinal cord (P<0.05). M Gln group and I/R group differed significantly (P<0.05) in behavior scoring, SOD activity, content of MDA, Glu, GSH, neuron number and deviation rate of spinal cord. Between H Gln group and M Gln group, there was no significant difference in behavior scoring, content of MDA and Glu, SOD activity, neuron number and aberration rate in spinal cord (P>0.05), whereas there was a significant difference in SOD activity and Giu content (P<0.05). Conclusion Pretreatment with medium-dose glutamine has a protective effect on spinal cord ischemia-reporfasion injury in rabbits, which may be related to the maintenance of GSH content, increase of SOD activity and reduction of MDA.

ABSTRACT
AIM:To observe the changes of hepatic fibrosis index,clinical symptom,physical sign and hepatic function after the patients were treated treatment with reduced glutathione hormone.METHODS:The 72 patients were divided into two groups that one was the treatment group with 37 patients and the other was the control group with 35 patients.The control group was accepted the treatment with Ganlixin Injection,Magnesium Aminosuccinate Injection and Mulvital,etc.The treatment group was accepted reduced glutathione hormone(1.5 g,once a day)in addition.The course of treatment lasted for 8 weeks.We observed the two groups' blood-serum fibrosis indexes(HA,LN,PIII-P,C-IV)and biochemistry indxes(TBIL,ALT,AST,GGT)before and after the treatment.RESULTS:The improvements of the treatment group were much better than the control group on the sides of clinical symptom,physical sign,hepatic function and blood-serum fibrosis.The treatment group's blood-serum fibrosis indexes were much lower after the treatment(P
