synaptonemal complex karyotype of zebrafish meiotic cells of zebrafish have been prepared to show synaptonemal complexes scs by light and electron microscopy completely paired scs from both spermatocytes and oocytes were measured to produce an sc karyotype the sc karyotype resembles the somatic karyotype of zebrafish and has no recognisable sex bivalent measurements of total sc length indicate that scs grow longer and develop centromeres during pachytene oocytes consistently have longer scs than spermatocytes presumably correlated with the reported higher recombination frequency in females than in males a review of papanicolaou smears in a black hospital results of 3009 papanicolaou smears from black women are reviewed the modus operandi and cost for the outpatient component are presented abnormal results were reported in 116 percent of the combined outpatients and inpatients the major portion of the changes in this subset were due to atypia present in a substantial number of women with trichomonas vaginalis vaginitis programs of this nature with a specific objective may be easily merged into the basic medical services provided by an outpatient and inpatient department
