Drug therapy of hemiballism. Review of the literature and personal observations

Hemiballism is a rare hyperkinetic disorder which is characterized by irregular vigorous rotatory movements of the limbs of one side of the body. The disabling and exhausting movements with their high risk of severe injuries require an acute drug treatment. However, there are no common guidelines for the treatment of this disorder. Therefore we reviewed the available literature to establish a concept for a rational symptomatic drug treatment. Furthermore, own observations in 6 patients with hemiballism of different origins are reported.     

Tumor heterogeneity and in vitro chemosensitivity testing in ovarian cancer

OBJECTIVE: Our purpose was to study the heterogeneity of drug response in fresh human ovarian tumors to chemotherapeutic agents in an in vitro chemosensitivity assay. STUDY DESIGN: This assay evaluates total tumor cell kill by measuring the intracellular adenosine triphosphate levels of untreated controls and drug-exposed cells at various doses after culture for 6 days. The surviving fraction is calculated by dividing the treated values with the control values. One hundred tumors were tested against four single drugs (cisplatin, the active metabolite of cytoxan, 4-hydroxyperoxy-cyclophosphamide, Taxol, and carboplatin) and two drug combinations (cisplatin plus 4-hydroxyperoxy-cyclophosphamide; cisplatin plus Taxol). RESULTS: There is great variation in the degree of cell death for single drugs and drug combinations among the 100 tumors tested. CONCLUSION: More effective clinical response to chemotherapy may be achieved in patients with ovarian cancer by selecting the most active drugs for chemotherapy, on the basis of in vitro chemosensitivity test results for individual patients.     

La2（MoO4）3：Eu均-花瓣状微／纳米结构的构筑及其荧光性能

在表面活性剂十二烷基硫酸钠（SDS）的作用下，采用温和的水热方法，成功制备了Eu掺杂的花瓣状L丑2（MoO4）3：Eu纳米微结构。这些形貌新颖的微米绒球的直径约3μm，由厚度30nm左右的纳米片次级结构单元自组装构筑而成，分散性良好，形貌规整、大小均一。通过XRD、SEM、TEM测试技术，研究了形貌的形成机理。由于具有良好的结晶度，这些花瓣状La2（MoO4）3：Eu纳米微结构显示出良好的发光性能。
