Rabbit's brain phospholipids (RBP) 100~200 mg ?kg-1 ip or sc showed anti-inflammatory action on four kind of acute inflammatory animal models. Cephalin and Lecithin were the effective component of antiin-flammatory action on the acute inflammatory animal model. But RBP did not show antiinflam-matory action on the chronic proliferative inflammatory model. RBP increased blood carbon particle clearance, perfaneal macrophage phagocytosis and enhanced lymphocyte proliferation,hemolysin antibody in normal and immunode-pression animal. RBP increased the cGMP content in the liver tissue of immunodepression animal, 0. 1~1 mg ?L-1 RBP promoted proliferation but 100 mg ?L-1 RBP inhibited proliferation induced by PHA in vitro on human lymphocyte.

A rare strain of actinomycetes, with broad-spectrum antimicrobial activity, was isolated from the soil samples from the farmland in the area of Yaohu lake in Nanchang. The information about the taxonomic identification, such as the morphology, physiological properties, cell components and 16S rRNA gene se-quences, suggested that the rare strain of actinomycetes was identified as Micromonospora carbonacea.

Based on the strain of Micromonospora carbonacea JXNU-1 with board-spectrum antimicrobial activity, the technology for the isolation and purification of antibiotic from the fermentation broth of the Micromonospora carbonacea, and its physical-chemical properties were studied. The results showed that, the antibiotic was stable under the condition of high temperature and alkali, but not in acid solution. After the pretreatment of centrifugation and filtration to remove the cells and lipids, the antibiotic was absorbed to negative exchange resin, and the impurity was excluded when 2 mol/L NaCl was used as primary eluent. The antibiotic could be eluted with 20% alcohol as eluent, and the eluting speed of the antibiotic was greatly accelerated as 2 mol/L NaCl was added into 20% alcohol as final eluent. Aqueous solution of the antibiotic was yielded from the alcohol-salt eluant by decompression concentration to wipe off alcohol and by dialysis to exclude salt. One active component was detected in antibiotic solution by paper chromatography, and theHPLC purity was over 99%. As the antibiotic shows positive color-forming reaction to Molish reagents, Benedict’s reagents and Diohenvlamine reagents, combined with the characteristics of absorption spectra, it is deduced that the antibiotic belongs to nucleoside antibiotics.

OBJECTIVETo evaluate the role of magnetic resonance imaging (MRI) in the diagnosis of lesions in the sellar region.

METHODSThe MRI data of 142 patients with surgically and pathologically proved lesions in the sellar region were retrospectively analyzed. Based on the MRI findings, the lesions were divided into pituitary adenoma and sellar region diseases except pituitary adenoma. According to the pathologic features, the sellar region diseases except pituitary adenoma were further divided into cystic lesions, parenchymatous lesions, and cystic and parenchymatous lesions.

RESULTSOf these 142 patients, pituitary adenoma was found in 30 cases, cystic lesions of sella region diseases except pituitary adenoma in 24. Further classification resulted in 66 cases of parenchymatous lesions and 22 cases of cystic and parenchymatous lesions.

CONCLUSIONMRI-based classification of lesions in the sellar region is useful for the diagnosis and differential diagnosis.

OBJECTIVE: To evaluate the feasibility of light transmission to measure focal cerebral ischemia in mice. METHODS: Persistent focal cerebral ischemia was induced by middle cerebral artey occlusion (MCAO) in mice. The brain were removed 24 h after MCAO and coronally dissected into 1 mm sections. Using a stereomicroscope, the brain section was illuminated with a halogen lamp and computerized images were stored. Next the brain sections were stained for 30 minutes with 0.5% TTC (2, 3, 5-triphenylterzolim chloride) at 37 degrees C. Using an image analyzer (AnalyPower 1.0), the infarct volumes obtained by light transmittance and TTC staining were calculated. Integrated gray scales of sections of both hemispheres were calculated by Photoshop 5.0. RESULTS: A close correlation existed between cerebral infarct volume measured by light transmission and TTC staining (r=0.81). The mean gray scales measured by both techniques of the ischemic hemispheres as well as those of the cortex, subcortex and hippocampus were siginificantly higher than those of non-ischemic hemispheres and of control mouse hemispheres (P <0.001). Further there were no significant difference between the two hemispheres of control mice and between hemispheres of control mice and non-ischemic hemispheres of the MCAO mice. CONCLUSION: Light transmission can be used for qualitative analysis of focal cerebral ischemia.

The 1H-NMR fingerprints of three different species tibetan medicine sea buckthorn were established by 1H-HMR metabolomics to find out different motablism which could provide a new method for the quality evaluation of sea buckthorn. The obtained free induction decay (FID) signal will be imported into MestReNova software and into divide segments. The data will be normalized and processed by principal component analysis and.partial least squares discriminant analysis to perform pattern recognition. The results showed that 25 metabolites belonging to different chemical types were detected from sea buckthorn,including flavonoids, triterpenoids, amino acids, carbohydrates, fatty acids, etc. PCA and PLS-DA analysis showed three different varietiest of sea buckthorn that can be clearly separated by the content of L-quebrachitol, malic acid and some unidentified sugars, which can be used as the differences metabolites of three species of sea buckthorn. 1H-NMR-based metabonomies method had a holistic characteristic with sample preparation and handling.

OBJECTIVETo investigate best diagnosing methods and therapy for patients with biliary tract complications after liver transplantation and analyze related factors.

METHODSA review was made of data collected from 96 patients, and confirmed by retrospective case notes examination.

RESULTSA total of 94 patients (97 grafts) survived more than 2 days after transplantation; of whom, 92 had an end-to-end biliary anastomosis with a T tube. The average follow-up was 5.8 months (range: 0.3 - 10.2 months). Among the 94 patients, eight (8.5%, 8/94) had complications: leakage during T-tube removal (2 patients), leakage at an earlier stage (2), simultaneous stricture and leak (2) and just stricture (2). Six patients with biliary tract complications had predisposing factors including hepatic artery stenosis (2 patients, including one hepatic artery stenosis combined with severe rejection, hepatic artery thrombosis (3), and donor-recipient bile duct mismatch (1). There was no difference in cold ischemic time. With hepatic artery thrombosis and/or stenosis > 50%, five patients were re-transplanted; without hepatic artery thrombosis and/or stenosis < 50%, three patients required endoscopic stenting and radiological percutaneous drainage of bile collection with or without balloon dilation. All patients survived.

CONCLUSIONSBiliary strictures occur later than leaks after surgery. Without hepatic artery thrombosis and/or stricture, there is no need for surgery; with hepatic artery thrombosis and/or stricture > 50%, re-transplantation is needed as early as possible.
