RESUMO
The first recorded incidence of dicephalia in a bull shark Carcharhinus leucas is reported from a foetus collected by a fisherman in the Gulf of Mexico near Florida, U.S.A. External examination, Radiography and magnetic resonance imaging revealed a case of monosomic dicephalia where the axial skeleton and internal organs were found to divide into parallel systems anterior to the pectoral girdle resulting in two well-developed heads.

In 95 patients with definite multiple sclerosis (MS) cerebrospinal fluid (CSF) cytomorphology, protein electrophoresis and immunoelectrophoresis using antisera to human serum, Fab fragments of immunoglobulin G(IgG) and to kappa and lambda light chains and the CSF IgG concentration were examined. In the CSF diagnosis of MS, the set of the examinations used is considered to be superior to any individual laboratory technique currently applied in the diagnostic process of MS. In the set of the CSF examinations, CSF immunoelectrophoresis revealed abnormal findings in patients with MS in whom presence of bands (oligoclonal gammopathy) in the gamma-globulin field of the CSF electropherogram and/or increased concentration of CSF IgG were not demonstrated.
