Human immunodeficiency virus (HIV) was detected by assay of reverse transcriptase activity in a "virus pellet" obtained by differential sucrose density centrifugation of cell-free semen from three patients with the acquired immune deficiency syndrome (AIDS), one individual with AIDS-related complex (ARC), and in an asymptomatic homosexual male.

Sperm adsorbed with retrovirus particles were recovered from the epididymis of apparently normal male mice. Epididymal semen from all four mouse strains examined was positive for retrovirus (10(5) to 10(8) particles per microgram of protein) indicating that epididymal fluids and sperm may be important vehicles for murine retrovirus spread.

The placenta of the Indian elephant is incompletely annular and zonary macroscopically and occupies the equator of an ovoid chorioallantoic sac. The amnion is fused with the chorion over the zone. Microscopically, the placenta is labyrinthine and endotheliochorial with a rudimentary marginal hematoma. Both macroscopically and microscopically it resembles(More)
Endarterectomy sections of canine aorta were examined in various stages of healing by scanning electron microscopy. In all specimens the endarterectomy site was quickly covered by a thin fibrin-platelet coagulum with varying amounts of thrombus. Neoendothelization began before one week and was virtually completed by one month except on areas of heavy(More)
Bilateral injections of aconitine in the preoptic-anterior hypothalamic area in rats produces pulmonary edema that is mediated by neurogenic mechanisms. The aim of the present study was to determine the efficacy of hypovolemia or intravenous methylprednisolone on preventing aconitine-induced pulmonary edema. Rats made hypovolemic before or after injection(More)
