Single-crystal ultraviolet spectroscopy, X-ray absorption spectroscopy and EPR measurements have been used to examine the oxidation and oxygenation state of the dinuclear copper site of several types of hemocyanin crystals. The crystals contain Panulirus interruptus hemocyanin which forms hexameric molecules with a molecular mass of approximately 470 kDa. Three types of crystals have been investigated. Type-I monoclinic crystals, which have been used for the X-ray structure determination, contain virtually only deoxyhemocyanin. Type-II monoclinic crystals, which are less well ordered than the type-I crystals, contain a mixture of deoxy, oxy and met forms. Older crystals contain relatively more methemocyanin. A third, hexagonal, crystal form is also partially oxygenated, and, like the type-II monoclinic form, subject to gradual conversion to methemocyanin.
The preliminary findings of a prospective controlled investigation to evaluate the effects of teaching child and adolescent psychiatry to medical students are presented. The results confirmed that the combined teaching of child and adolescent psychiatry, psychiatry and paediatrics led to significant changes as assessed using a multiple choice questionnaire and an attitude questionnaire. Students who had received the combined teaching acquired greater knowledge and more positive attitudes. Caution is warranted when interpreting the results, however, due to the multiplicity of factors affecting outcome: the absence of any measure of the acquisition of clinical skills; no attempt to determine separate or interactive effects of psychiatry and paediatric teaching; and no measure of stability of the changes over time.
Medical student opinion of the various methods used to teach child and adolescent psychiatry at Westminster Medical School, London was determined with reference to four general teaching objectives. Their ratings and comments concerning the different methods were used to evaluate the various techniques and make suggestions concerning the planning of undergraduate teaching programmes in child and adolescent psychiatry.
