Evidence that sperm cells share or impart antigenic specificities to fertilized ova and cleaving embryos in animals was first demonstrated indirectly in female an-imals isoimmunized against sperm or testis cells. While early studies often gave conflicting results, postfertili-zation infertility effects were occasionally reported.1 The systematic analysis in animals of anti~ertility e~ects after immunization with sperm or testis preparations resulted in a clearer delineation of the affected stages and modes of action. In a study of the effects of antisperm antisera on the fertility of sperm in rabbits, Kiddy et al. reported t~~t a dilution of serum that permitted near-normal fertiliza-tion rates resulted in significantly lowered levels of em-bryo survival.f Isoimmunization offemale ani~alswi~h sperm or testis preparations has often produced mcon~Is tent results regarding the degree and stage at which infertility occurs; however, studies in which antifertility By invitation...

neurofibromatosis type 1: concepts and

Silicosis — is a Continued chronic lung disease associated with the inhalation and pulmonary deposition of dust that contains crystalline silica. Through the Sentinel Event Notification System for Occupational Risks (SENSOR) * program, CDC’s National Institute for Occupational Safety and Health (NIOSH) is assessing practical models for implementing state-based surveillance of silicosis and linking follow-up intervention activities to surveillance reports. From 1989 through 1992, the Ohio Department of Health (ODH) SENSOR program identified silicosis cases through reports of Bureau of Workers’ Compensation (BWC) claims, physician reports, and death certificates. The addition in 1993 of hospital discharge reports as an ascertainment source resulted in a substantial increase in the number of silicosis case reports identified annually (Table 1). This report describes the investigation of a case of occupational silicosis in Ohio and summarizes the impact of hospital-based reporting on surveillance for silicosis in Ohio during 1993–1994. Case Report In September 1991, a case report † was sent to ODH by an infectious disease specialist

witnessed a man beating his wife or girlfriend and that 14 % of women report that a husband or boyfriend has been violent with them (1). Studies suggest that as many as 30 % of women treated in emergency departments (EDs) have injuries or symptoms related to physical abuse (2). A national health objective for the year 2000 is for at least 90 % of hospital EDs to have protocols for routinely identifying, treating, and referring victims of sexual assault and spouse abuse (objective 7.12) (3). The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) has also recommended that accredited EDs have policies, procedures, and education in place to guide staff in the treatment of battered adults (4). To assess progress toward the national health objective for the year 2000 and the JCAHO standards, all active EDs in California were surveyed during November–December 1992 about their policies and practices for the treatment of battered adults. This report presents findings of this survey. The survey was conducted by the Family Violence Prevention Fund (FVPF) in collaboration with the San Francisco Injury Center for Research and Prevention (SFICRP).

Influenza From mid-November — Continuedthrough December 1993, influenza activity in the United States increased. This report summarizes surveillance information regarding influenza activity in the United States from October 3, 1993, through January 1, 1994. As of January 1, 1994, influenza viruses had been reported in 46 states; four states had not documented the presence of influenza this season (Delaware, Mississippi, New Hampshire, and Rhode Island). Nearly all (99%) influenza isolates reported to CDC have been influenza type A; one influenza type B virus was isolated in New York. Of the 750 influenza type A viruses reported from the World Health Organization (WHO) collaborating laboratories, 409 were subtyped as type A(H3N2) and 16 as type A(H1N1); 325 were not subtyped. As of January 10, 208 influenza isolates had been received by the WHO Collaborating Center for Influenza at CDC for antigenic analysis. Of the 68 influenza type A(H3N2) virus isolates completely analyzed, all were antigenically related to the A/Beijing/32/92(H3N2) strain included in the 1993–94 influenza vaccine. The ratio of specimens positive for influenza virus to total specimens submitted for respiratory virus testing increased from less than 0.01 in previous weeks to

upercritical fluids have been used as unique solvents in a number of analytical techniques (l), such as nuclear magnetic resonance spectroscopy (2), thin-layer chroma-tography (TLC) (3), and field flow fractionation (4). The ana-lytical chemist, however, normally associates the prefix “supercritical fluid ” with chromatographic or extraction meth-odologies that have been extensively developed within the past 15 years. The “renaissance ” of supercritical fluid chromatogra-phy (SFC) occurred in the mid-1970s, largely as a result of improvements in injection and pumping devices, enhanced column efficiencies, and the refinement of transport mecha-nisms to deliver the separated solutes to modified gas (CC) and liquid chromatographic (LC) detectors (5). By contrast, super-critical fluid extraction (SFE), despite a long history as a phys-icochemical phenomenon (6) and a recent plethora of
