4.Protection of indole-3-carbinol against ethanol-induced hepatotoxicity in precision liver-cut slices of rats
Chinese Pharmacological Bulletin 1986;0(06):-
AIM To study the hepato-protection of indole-3-carbinol (I3C), one of glucosinolate compounds in cruciferous vegetables, on ethanol-induced hepatotoxicity. METHODS Ethanol 50 mmol?L -1 was used to induce hepatotoxicity in precision liver-cut slices of rats. The release of glutamic pyruvic transaminase(GTP), glutamic oxaloacetic transaminase (GOT), lactate dehydrogenase (LDH) and glutathione S-transferase (GST) into culture medium, and aniline hydroxylase (ANH) and alcohol dehydrogenase (ADH) in cytosol of hepatocytes in the precision liver-cut were measured with different doses of I3C. The histopathological observation of liver slices was also done to evaluate the effect of I3C. RESULTS The release of GTP, GOT, GST and LDH in the medium increased significantly when the slices were treated with 50 mmol?L -1 ethanol for 4 h. I3C at concentrations of 100~400 ?mol?L -1 effectively reduced the release of GTP, GOT, GST and LDH in the medium of ethanol-treated slices. Meanwhile, the activities of cytosol ANH and ADH decreased to the normal levels. The histopathological changes of liver slices induced by ethanol were lessened by I3C treatment. CONCLUSION I3C can markedly protect rat liver slices from ethanol-induced hepatotoxicity, which partly results from the change of ethanol metabolism in liver.

Chinese Journal of Tissue Engineering Research 2001;5(23):154-155
Objective To observe rehabilitation and functional prognosis of patients suffered from brain infarction of acute phase complicated by depression. Method We selected 38 cases of acute brain infarct complicated with depression disorder as depression group, 40 cases of non- depression patient admitted at the same period were selected as non depression group.Antidepressants drugs administration and rehabilitation therapy were performed.We evaluated patients according to functional independence measure(FIM)of Chinese edition. HAMD grading comparison was carried out in depression group. Result Before treatment,two groups score nearly the same,compared with pretreatment. After treatment,patients in depression group and non depression group showed significant improvement esp non- depression group (P<0.01).11 cases with severe depression in the depression showed no changes in FIM score before and after treatment. Conclusion Compared with non- depression patients,functional recovery of patients with depression following brain infarction of acute stage is much slower,especially for patients with severe depression.

Chinese Journal of Anesthesiology 2011;31(2):144-146
Objective To compare the effect of different methods of anesthesia on cerebral autoregulation in patients undergoing neurosurgery.Methods Sixty-nine ASA Ⅱ orⅢ patients with brain tumor, aged 23-62 yr, scheduled for neurosurgery under general anesthesia, were randomly divided into 3 groups ( n = 23 each) : propofol-remifentanil group (group PR), sevoflurane-remifentanil group (group SR) and propofol-sevoflurane-remifentanil group (group PSR) . Anesthesia was induced with target-controlled infusion (TCI) of propofol (target plasma concentration3 μg/ml, PR and PSR groups) or inhalation of 8% sevoflurane (group SR) and iv injection of remifentanil 1 mg/kg and atracurium 0.5 mg/kg. The patients were mechanically ventilated after tracheal intubation. PETCO2 was maintained at 32-35 mm Hg. Anesthesia was maintained with TCI of propofol (target plasma concentration 2.0-3.5 μg/ml) in group PR, with inhalation of 1.5%-2.5% sevoflurane in group SR, with TCI of propofol (target plasma concentration 1.5-3.0 μg/ml) and inhalation of 1% sevoflurane in group PSR, and with TCI of remifentanil (target plasma concentration 2.0-4.5 ng/ml) and iv infusion of atracurium at 6 μg · kg-1 · min-1 in all groups. Auditory evoked potential index was maintained between 40-45. The middle cerebral artery time-average peak flow velocity was recorded before induction (baseline) , immediately after intubation, immediately before craniotomy and at the beginning of skin suture. The unilateral carotid artery was compressed for 7 s at the corresponding time points mentioned above. The transient hyperemic response ratio (THRR) was calculated to reflect cerebral autoregulation. Results Compared with the baseline value at T0, THRR was significantly increased at T2in group PR and decreased at T2,3 in group SR (P <0.05) ,while no significant change was found in THRR at T1-3in group PSR (P >0.05). The THRR was significantly lower in SR and PSR groups than in group PR, and higher in group PSR than in group SR ( P < 0.05). Conclusion Propofol-remifentanil anesthesia can improve cerebral autoregulation, sevoflurane-remifentanil anesthesia can reduce cerebral autoregulation, and propofol-sevofluraneremifentanil anesthesia exerts no effect on cerebral autoregulation in patients undergoing neurosurgery.
