  • Experimental Study on Gut Mucosal CellMediated Immunity after Major Hepatectomy and Its Relation to Bacteria Translocation in Rats

    ObjectiveTo investigate the change of cellmediated immunity in gut mucosa after major hepatectomy and to study its relationship with the bacteria translocation.MethodsFortyeight Spraguedawley adult male rats were randomly allocated into two groups, the sham operation group and the operation group. Besides without the hepatectomy, the sham operation group has the same course with the operation group. Seventy percent hepatectomy rats are divided as postoperative 6 h group (n=6),12 h group (n=6),24 h group (n=6) and 72 h group (n=6). Sixhour, 12hour, 24hour and 72hour after operation specimens were taken from jejunoileum respectively. Immunohistochemical staining was performed on frozen sections and image pattern analysis was used. We also investigate the change of liver function. ResultsTwentyfour hours and 72 hours after 70% hepatectomy, there was a significant reduction in the number of CD3+,CD4+and CD8+ T lymphocytes in the mucosal lamina propria of the operation group compared with the sham operation group (Plt;0.05). There was significant difference between these two groups in liver function change (Plt;0.05).ConclusionThere is an altered pattern of intestinal mucosal T lymphocytes after major hepatectomy, then the local cellmediated immunity was depressed, which may be the cause of translocation of enteric bacteria.

  • Measurement and Significance of Serum Nitric Oxide Level in Patient with Obstructive Jaundice and Renal Dysfunction

    ObjectiveTo study the change and significance of the serum nitric oxide (NO) level in patient with obstructive jaundice complicated with renal dysfunction. MethodsThe level of NO, BUN, Cr in serum and the activity of NOS in 25 patients with obstructive jaundice and renal dysfunction and 26 healthy adults was studied.ResultsThe patients’ serum NO level and the activity of NOS were significantly lower than those in the control group(P<0.01),whereas the serum BUN and Cr levels were significantly higher than those in control group(P<0.01). The linear correlation analysis showed that the serum NO had a negative correlation between serum BUN and Cr level (P<0.01). ConclusionThe patients with obstructive jaundice and renal dysfunction may lead to the decrease of serum NO level. NO may have some protective effects to the renal function during obstructive jaundice.
