The results of topical application of 13-cis-retinoic acid on basal cell carcinoma. A correlation of the clinical effect with histopathological examination and serum retinol level

A group of 50 patients with basal cell carcinoma of the face was treated by 13-cis-retinoic acid. The treatment resulted in diminution of the tumors. Complete regression was observed in 4 cases. Histological examination revealed necrosis of cancer cells and mononuclear infiltration into the treated tumors. In the group with weak clinical and histological reaction to the treatment all basal cell carcinomas were of adenoid type. A better effect was observed in the group with lower serum retinol level. This treatment method seems to be supplementary to surgery in prevention of the tumor recurrence.     

Characterization of the anti-neural antibodies in the Sera of leprosy patients

Sera from 43 leprosy patients were tested for antibodies that bound to normal human nerve. Thirty-eight percent showed positive staining as demonstrated by indirect immunofluorescence. Only 1 out of 30 control sera tested displayed similar staining. Western blots of myelin and neural intermediate filament (IF) proteins were tested with patient sera. Two of the anti-neural antibody (ANeAb)-positive leprosy sera bound to the P0 protein of PNS myelin. All 17 ANeAb-positive leprosy sera displayed 2 or more bands in the molecular weight range of Mr 45 000-55 000, when tested against IF proteins. One explanation for these findings is that leprosy patients produce antibodies to intermediate filament (IF) proteins released subsequent to the bacterial invasion of the peripheral nerves. The importance of these autoantibodies in the pathogenesis of leprosy is discussed.     

Antibody reactivity to a synthetic peptide (P62) of the Epstein-Barr nuclear antigen in sera of patients with X-linked lymphoproliferative syndrome

An enzyme-linked immunosorbent assay (ELISA) was used to measured IgG antiboody titers againt a synthetic peptide whose sequence was derived from the glycine-alanine repeating region of Epstein-Barr virus nuclear associated antigen 1 (EBNA-1). Antibody titers were determined in sera from 15 normal subjects, sera from 21 normal male siblings of X-linked lymphoproliferative syndrome (XLP) patients, from 20 XLP patients comprising a total of 42 samples, and ten samples before and ten samples after gamma-globulin therapy in ten patients with XLP. Data analysis demonstrated that while there are differences between the ELISA and ACIF, they appear to measure a similar response as demonstrated by their correlation coefficient (0.77) and the GMT to EBNA observed by both methods. No cross-reactivity of cytomegalovirus antibodies to the EBNA-1 peptide was observed by immunobv using adsorption against AD-169 infected MRC-5 cells.. However, non-specific binding was observed if samples were not pre-incubated in a 10% goat serum PBS-Tween 20 solution. This pre-treatment removed the non-specific binding that falsely elevated GMT in approximately 15% of both normal and XLP samples in ELISA. The ELISA system appears to be a sensitive, reproducible and objective test that may be useful for assessing the antibody responses of patients to the EBNA-1 protein.     

Assessing reflective writing on a pediatric clerkship by using a modified Bloom's Taxonomy.

OBJECTIVE: Reflection enables learners to analyze their experiences and capture the wisdom that lies within. Effective teaching requires reliable methods of assessment. Several methods of assessing reflective writing have been described; however, they often require significant training, and reliability has seldom been assessed. This study was designed to determine the interrater reliability of a method of assessing reflective writing by using a modified Bloom's Taxonomy. METHODS: Twenty-one third-year medical students maintained reflective journals throughout their pediatric clerkship. A coding schema based on Bloom's Taxonomy was developed to assess the level of cognitive processing evident in the journals. Journals were independently assessed by 3 raters. Percent agreement, kappa statistics, and intraclass correlation coefficients (ICC [2,1]) were used to assess interrater reliability. RESULTS: Three hundred eight entries from 21 journals were assessed. Percent agreement ranged from 78.2% to 100%. Kappa statistic for each level ranged from 0.57 +/- 0.04 to 0.73 +/- 0.04, and for the highest level of processing evident it ranged from 0.52 +/- .04 to 0.58 +/- 0.04. ICC (2,1) for each level of cognitive processing ranged from 0.62 (F = 6.20; P = .000) to 1.00, and for the highest level of cognitive processing evident, it was 0.79 (F = 12.42; P = .000). Substantial to almost perfect agreement was attained. CONCLUSIONS: Reflective journals allow learners to revisit their experiences for critical analysis and deeper learning. This study describes a reliable method, based on Bloom's Taxonomy, of determining whether learners have achieved higher order thinking through reflective journal writing. This method can provide a baseline for facilitating higher order processing, critical thinking, and reflective practice.     

钚-239对大鼠胸腺淋巴细胞超微结构的影响

本文观察了硝酸钚溶液经腹腔一次注入大鼠体内,不同时间后胸腺淋巴细胞超徽结构损伤效应与修复规律.早期可见淋巴细胞质膜及内膜系统的变化,以后出现核损伤,注后20天损伤最严重。以小淋巴细胞的损伤更明显。注后1月细胞损伤有所减轻,6个月基本恢复正常。     

国产奎硫平合并舒必利治疗难治性精神分裂症

目的:了解舒必利合并国产奎硫平(启维)治疗难治性精神分裂症的疗效和安全性。方法:26例符合CCMD-Ⅲ精神分裂症诊断标准且临床判断属于难治性病人,予舒必利合并奎硫平治疗,疗程8周,分别在治疗前及治疗后进行阳性与阴性症状量表(PANSS)和不良反应状量表(TESS)评定。结果:合并治疗8周后总有效率65.3%。PANSS阳性、阴性及一般精神病理评分于治疗前后均有显著差异(P<0.01)。TESS总分治疗前后无显著差异(P>0.05)。副反应主要为肌张力增高、失眠、体重增加、静坐不能。结论:对于舒必利治疗反应不佳的难治性精神分裂症病人合并奎硫平治疗仍可取得较好的临床效果,安全性较高,耐受性及依从性好,可作为临床治疗难治性病人的方法之一。
