Objective To evaluate the diagnostic level of infantile vitamin B_1 deficiency encephalopathy.Methods Clinical featuresand CT images in 45 cases of infantile vitamin B_1 deficiency encephalopathy proved by clinical treatment and follow-up were analyzedretrospectively.Results CT images depicted bilateral symmetrical low-density regions in the lentiform nucleus and the head of caudatenucleus in all 45 cases.The regions were reniform,upsiloid,butterfly or oval.Bilateral symmetrical low-densities of frontal,temporal or parietal lobes were found in some cases.Other CT findings included extensions of longitudinal fissures,lateral fissures and cerebral grooves.Experimental treatments of vitamin B_1 made remarkable clinical improvements.Conclusion CT scanning is extremely useful in thediagnosis of infantile vitamin B_1 deficiency encephalopathy.

Naive and chronically infected C57BL/6 mice were challenged percutaneously over the ear pinna with Schistosoma japonicum cercariae. After 15 hours, the number of EOS increased significantly in the skin of chronically infected mice. Inflammatory cells aggre-gated in the vicinity of schisto.somula or entrapped intact and disintegrated schistosomula, forming granulocytic micro-abscesses in both groups. Ultrastructure studies revealed that flattened EOS tightly attached to the schistosomulum surface and degranulated. Local tegument damage occurred in the area of attacbment. NEU adherence did not seem to be as intimate as EOS, and degranulation was not seen. The tegument of the attached schis-tosoniulum remained normal. The result suggested that EOS appeared to be the efficient killer cell against skin phase schistosomula of S. japonicum (Figs. 1-6).

Eight murine monoclonal antibodies against surface determinants of Schistosoma japoni-cum (Chinese mainland strain) schistosomula were generated,of which only one monoclonal IgM antibody (N15D9) gave protection at level ranging from 14 to 39% in experiments of passive transfer or inhibition of infectivity while the others did not exhibit significant levels of passive protection.Further characterization of N15D9 antigen specificity showed that 96 and 14 kDa antigen molecules in cercaria,and 132 and 10 kDa in schistosomula could be recognized by N15D9 in Western blot assay.Furthermore,the 96 and 132 kDa molecules could also be recognized by pooled infected human sera while 14 kDa and 10 kDa only by sera from mice vaccinated with 3-hour schistosomula.The molecules recognizable by N15D9 were surface epitopes repeatedly expressed on cercaria,in vitro 3-hour mechanically transformed schistosomula and 5 day lung-stage schistosomula,as demonstrated by indirect immuno-fluorecence surface binding assay.

In this study, antibody-dependent murine neutrophil-mediated cytotoxicity (ADCC)against schistosomula of Schistosoma japonicum (Chinese strain) were demonstrated in vitro by use of immune effector mechanism analysis system. The results showed that neutrophils from the normal mice could mediate the antibody-dependent ADCC reaction against the schistosomula of Schistosoma japonicum, This ADCC reaction was not dependent on the complements, the complements could not enhance the ADCC reaction mediated by the neutrophils.

Objective To evaluate the diagnostic value of contrast-enhanced CT scans in diagnosis of traumatic splenic rupture. Methods The findings of unenhanced and contrast-enhanced CT scans of 34 cases with traumatic splenic rupture confirmed by operation were retrospectively reviewed. Results Of the 34 patients, the diagnoses of splenic rupture on unenhanced CT scans were certain in 23 patients and uncertain in 6 patients. No abnormalities were found in 5 patients(sensitivity 85.3%, specificity 67.6%). After intravenous administration of contrast material, all of the patients were diagnosed as splenic rupture(sensitivity 100%,specificity 100%).Conclusion Contrast-enhanced CT is important in diagnosis of traumatic splenic rupture and can obviously improve the diagnostic accuracy. It provides reliable information for clinical treatment.

Objective To explore the medication rules of State Medical MasterYan Zhenghua. Methods The prescriptions containing Radix Paeoniae Alba that prescribed by Pro.
