摘要:
A modular knee prosthesis system includes a femoral component having a stem and a sleeve. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by controlling the relative axial positions of the stem and the sleeve. Alternative options include providing sleeves with tapered bores of different diameters, providing a shim to be placed between the sleeve and the stem and providing the stems as adapters having different diameters.
摘要:
An improved diluent for the preparation of cisplatin suspensions from a lyophilized powder is provided. The diluent contains a pharmaceutically acceptable nonionic surfactant, which improves the accuracy and homogeneity of the therapeutic formulation. The suspension may be used directly, or may be used in preparing gel formulations for direct injection into a neoplastic lesion or surrounding tissue.
摘要:
Disclosed are translucent proteinaceous compositions comprising collagen and an effective amount of a compatible cytotoxic drug which compositions are characterized by having a single collagen transition temperature of less than about 45.degree. C. Such compositions possess enhanced retention of the cytotoxic drug at the site of injection and are optically translucent.
摘要:
Methods and compositions are provided for the treatment of a host with a cellular proliferative disease, particularly a neoplasia. In the subject methods, a pharmaceutically acceptable, substantially anhydrous, injectable semi-solid composition which acts as a depot for a cytostatic agent, is administered to a lesion of the disease, particularly intralesionally. The subject compositions comprise a water immiscible, fatty acid ester matrix and a cytostatic agent.
摘要:
A liquid pharmaceutical composition comprising an effective amount of non-lyophilized gamma-interferon. The liquid pharmaceutical composition which additionally includes a buffer capable of maintaining the pH of the liquid composition within the range of 4.0 to 6.0, a stabilizing agent and a non-ionic detergent.
摘要:
The elastic modulus and density of an amorphous, ceramic article derived from a resinous organosilicon polymer and having a composition consisting essentially of silicon, nitrogen and/or carbon are increased while substantially maintaining or improving tensile strength by heat treating the ceramic article at an elevated temperature under superatmospheric nitrogen pressure to increase its density while avoiding crystallization. During heat treatment, at least some of the conditions of time, temperature, heating rate, cooling rate, pressure and atmosphere are controlled to minimize erosion of the article which could otherwise occur due to the loss to the surrounding atmosphere, as a gas or gaseous component, of at least one of nitrogen, silicon and carbon. The heat treated, ceramic article is amorphous and non-crystalline and has a density substantially greater than 2.5 g/cc together with desirable values of tensile strength and elastic modulus.
摘要:
Apparatus for passively exercising the human extremities includes an elongate track (16) comprising a tubular housing (46) having a slot formed in the bottom thereof. A lead screw (62) is longitudinally disposed in the housing and a carriage (26) is threadably engaged with the lead screw (62). The carriage (26) is connected to the extremity to be exercised, so that upon movement of the carriage (26) back and forth along the elongated track (16) the extremity is moved through a pre-determined range of motion. Stop members (28) are positionable on the housing in the path of movement of the carriage (26). Engagement of the carriage (26) with the stop member (28) effects longitudinal shifting of the lead screw (62). Longitudinal shifting of the lead screw (62) actuates switches (110) which reverse the direction of rotation of the lead screw (62) thereby reversing the direction of movement of the carriage (26).
摘要:
A monitoring circuit for a door operating D.C. electric motor, the circuit comprises a first means for detecting a back EMF of the motor and producing a load signal indicative of the magnitude of the back EMF, a second means for detecting the time rate of change of the load signal and issuing an obstruction signal if the magnitude of the time rate of change of the load signal exceeds a predetermined value.
