Abstract: A benzoyl urea compound-albumin complex comprising a benzoyl urea compound of the formula: ##STR1## wherein X is a halogen atom or a nitro group, Y is a hydrogen atom, a halogen atom, a nitro group or a trifluoromethyl group, Z.sub.1 is a halogen atom or a trifluoromethyl group, Z.sub.2 is a hydrogen atom or a halogen atom and A is CH or a nitrogen atom, and albumin.

Abstract: Use of a benzoyl urea compound of the formula: ##STR1## wherein X is a halogen atom or a nitro group, Y is a hydrogen atom, a halogen atom, a nitro group or a trifluoromethyl group, Z.sub.1 is a halogen atom or a trifluoromethyl group, Z.sub.2 is a hydrogen atom or a halogen atom, and A is CH or a nitrogen atom, as an antiviral agent.

Abstract: An instrument for induction of labor comprising a tubular member or catheter being closed at its forward or leading end and open at its rearward or trailing end; there being an inflatable bag or balloon in enveloping relationship to the forward end portion of the catheter and being engaged in leak-proof manner thereto. At least one orifice is provided adjacent the forward end of the catheter within the bag for effecting communication between the said bag and the catheter for the introduction of liquid into the bag for inflating same to a predetermined extent dictated by the presentation of the fetus. A method for inducing labor comprising inserting into the uterus a liquid inflatable bag mounted upon the forward end portion of a tubular member with the bag being presented between the uterine wall and the amniotic membrane.

Abstract: An intrauterine device constructed of a flexible plastic and comprising a stem having adjacent one end a plurality of arms or branches extending laterally therefrom and being biased slightly in a direction toward the opposite end; the planes of said arms being at an angle of less than 90.degree. to the plane of the stem and said arms being flexible about their juncture of engagement to said stem for bending toward or opposite the remote end thereof. Said stem remote from said arms is relatively thin and elongated and with there being a hook in its said remote end extremity. A tool for inserting said device is provided having a chamber for accepting the thin elongated portion of said device and finger-like guides embracingly engaging opposite sides of said stem between arms thereof and having its device engaging portion formed on a radius for promoting facile disengagement from the device upon limited longitudinal tilting of the tool when the device is in operative position.
