Neural site of strabismic amblyopia in cats: spatial frequency deficit in primary cortical neurons

Summary The acuities of cells in the primary visual cortex of five tenotomized strabismic cats were measured. Previous behavioural studies have shown such animals to possess a severe amblyopia of approximately 1.5 octaves of spatial frequency, yet the acuities of both retinal ganglion and lateral geniculate X-cells are normal. The receptive fields of the cortical cells sampled were within 5° of the area centralis projection. On average, the acuities of cortical cells driven by the amblyopic eye were nearly 1 octave less than those for the non-deviating eye. However, the best cell acuities for each eye were nearly the same. The relationship between ocular dominance and cell acuity was found to be different for the two eyes despite a symmetrical ocular dominance distribution. The acuity deficit for cells driven through the amblyopic eye was present at all depths along the electrode tracks. We conclude that in this model amblyopia, the initial spatial processing deficit lies in the visual cortex, and most probably in the cells of layer IV. Further-more, the presence of a few cells driven by the amblyopic eye which can perform nearly as well as those from the fellow eye in processing high spatial frequencies gives new insight into the way in which strabismic and deprivation amblyopias differ.     

阴道镜下高频电灼术联合α-2a干扰素凝膏治疗尖锐湿疣疗效分析

目的探讨阴道镜下高频电灼术联合重组人干扰素α-2a治疗尖锐湿疣（CA）的效果。方法将165例CA分为3组，A组应用阴道镜下高频电灼术联合重组人干扰素α-2a；B组单纯采用阴道镜下高频电灼治疗；C组应用NS-FII型多功能光谱治疗仪联合肌注重组人干扰素α-2a。结果治疗后3-6个月A、B、C组复发率分别为0％、4．4％、65．4％：半年后人乳头瘤病毒（HPV）转阴率分别为93．5％、85．4％、43．8％，A组明显优于B组，B组明显优于C组，3组比较差异有统计学意义（P〈0．01）。结论阴道镜下高频电灼术联合重组人干扰素α-2a治疗CA可明显降低CA复发率和提高HPV转阴率。     

Immunohistochemical localization of syndecan-1 in normal and pathological human uterine cervix

Expression of syndecan-1, a cell surface proteoglycan that binds growth factors and extracellular matrix components, was studied in normal and pathological human uterine cervix using immunohistochemical methods. Normal cervical squamous epithelium showed positive staining for syndecan-1 in all cell layers, except the basal cell layer, whereas endocervical columnar epithelium stained weakly. In non-neoplastic reactive lesions, metaplastic squamous cells were positive for syndecan-1, whereas columnar cells showed weak or negative staining. In cervical condylomas, cells showing koilocytotic atypia were positive for syndecan-1. The progression of cervical intraepithelial neoplasia (CIN) grade I to grade III was associated with reduced syndecan-1 expression and localization of syndecan-1 to more superficial cell layers. In squamous cell carcinomas (SCCs), syndecan-1 expression correlated with histological differentiation, being absent from most poorly differentiated tumours. The results suggest that loss of syndecan-1 from atypical cells is an early event during cervical carcinogenesis and show a close association of syndecan-1 expression with preserved epithelial morphology and differentiation.     

尖锐湿疣皮损中朗格汉斯细胞的变化

目的了解尖锐湿疣(CA)皮损中朗格汉斯细胞(LC)的变化。方法采用免疫组化法对34例CA皮损进行LC染色,光镜下观察其形态和数量变化,并对其中6例标本行电镜观察。结果与正常皮肤相比,CA皮损表皮内LC分布不规则,少见典型的树突状细胞,细胞突明显减少、缩短或消失,半定量计数显示CA皮损中LC为(13.15±9.42)个,较正常明显降低(P<0.01)。超微结构表明LC中的特征性结构———朗格汉颗粒(LG)不仅数目减少,而且形态也不典型。结论CA皮损中LC形态及数量均发生变化,可能在CA的发病中起着一定作用。
