Conjunctivitis and pterygium associated with the American Indian type of polymorphous light eruption

We describe three patients with the American Indian type of polymorphous light eruption (actinic prurigo), two Cree Indian sisters and a Cree Indian boy, who had eye symptoms similar to those seen in limbal-type vernal catarrh.     

Concurrent systemic cryptococcosis and haemangiosarcoma in a dog

A young dog with progressive neurological signs was humanely killed by the injection of barbiturate for postmortem examination. Lesions in the nose, lung, pancreas, lymph nodes, kidneys and the meninges were heavily infiltrated with Cryptococcus neoformans. In addition, haemangiosarcoma was detected in the right atrium. The finding of systemic mycosis and neoplasia together in a young dog suggests an immunosuppressed state.     

Family system test (FAST): Are parents' and children's family constructs either different or similar,or both?

Perceptions of family cohesion and hierarchy structures were assessed by theFamily System Test (FAST), a clinically-derived figure placement technique. Parents (N=140) and their preadolescent offspring (N=70) completed typical and conflict representations in individual as well as group settings. Typical representations were characterized by balanced family structures (i.e. cohesive and moderately hierarchical) and those displaying conflict situations showed predominantly unbalanced patterns. FAST portrayals were related to respondent (mother vs. father vs. child). Fathers represented typical family relations as balanced more often than mothers. Regarding conflict representations, children were more likely than fathers to portray the family as unbalanced. However, analyses of representations of the same family (i.e. intra-family comparisons) indicated that all respondents differed in their perceptions and, that fathers' typical portrayals showed most often the same structure as those done by the family members as a group.     

神经系统功能磁共振联合应用研究进展

随着磁共振功能成像技术的发展,尤其是弥散张量成像(d iffusion tensor,DTI)及血氧依赖水平磁共振成像(b lood ox-ygenation level dependent,BOLD)技术的日臻完善,在活体状态下显示活动的皮质区并无创跟踪脑内白质纤维,反映解剖连通性已成为可能。本文就功能磁共振BOLD、DTI联

North West Group Society for Occupational Medicine: a retrospective view

Professor Nicola Cherry has taken the Chair of OccupationalMedicine at Manchester University. At a unique event on 28 February1991, the three Emeritus Professors met Professor Cherry ata meeting held at the A.M.I. Alexandra Hospital, Cheadle, Manchester.The meeting organized by the North West Group of the SOM, includeda tour of the hospital followed by a buffet supper. ProfessorLane (now aged 94) introduced Professor Cherry who gave a talkon her first impressions on return from McGill University andher future objectives. Over 70 members of the SOM, BOHS andRCN Greater Manchester Group of OH nurses attended.     

头孢噻肟钠聚合物测定实验条件的改进

目的:对中国药典收载的头孢噻肟钠聚合物测定条件进行改进。 方法 :采用高效液相色谱法 ,以Sephadex G- 10色谱柱 4 2 cm× 1.3cm对 6批样品进行分析 ,分别进样 5 0μl和 2 0 0μl,按外标法计算聚合物的量。结果:头孢噻肟钠在 10～ 6 0 μg/m l范围内线性关系良好 (r=0 .9995 ) ,高中低浓度的加样回收率分别为 10 0 .2 %、10 0 .4 %、99.7% ;RSD分别为 1.7%、1.5 %、1.9% (n =3)。该方法与药典方法比较 ,差异无统计学意义 (P >0 .0 5 )。 结论:本方法简便、快速、可行 ,具有实用价值     

668颗后牙镍铬合金PFM边缘适合性的临床观察

目的：观察采用2种边缘形式的后牙烤瓷熔附金属全冠边缘适合性和对牙龈健康的影响.方法：对668颗后牙,分别采用2种边缘形式的后牙烤瓷熔附金属全冠（单冠或桥的基牙）在修复2年后进行复查,检测其边缘适合性及牙龈指数（GI）和牙周探诊深度（PD）,用统计学方法分析修复体边缘形式与牙龈病变间的关系.结果：采用羽状边缘360°金属脚边的PFM边缘适合性明显优于凹面肩台型边缘PFM,凹面肩台型边缘的PFM的牙龈病变发生率,明显高于羽状边缘360°金属脚边的PFM,而边缘适合性差者较适合性好者牙龈病变发生率显著增高.结论：后牙PFM的边缘采用羽状边缘360°金属脚边是一种好的选择.
