Abstract: Fibrin degradation products stimulate cell proliferation and angiogenesis. The present invention provides peptides, analogs, and antibodies which are useful in the modulation of binding fibrin fragment E to cell receptors and the modulation of such activity.

Abstract: Apparatus for removing biological material from a body thereof comprising a hollow tubular elongate member, one end of which can engage biological material to be removed, a casing in which a portion of the tubular member is mounted for longitudinal sliding movement, a motor which is connected to the casting and has a rotatable drive shaft, means for coupling the rotation of the drive shaft to the tubular member so as longitudinally to vibrate the tubular member and means for withdrawing removed biological material up the tubular member from the said end thereof.

Abstract: An ultrasound unit for the clinical application of hyperthermia to tumor cells in soft tissue. The ultrasound hyperthermic unit includes in one aspect an array of sonic transducers (1) radially disposed about an axis and angled to direct sonic energy (12) towards said axis at a point remote from said array, each transducer being adapted for angular movement relative to the other transducers thereby to allow adjustment of the shape of the acoustic focus. The array is computer controlled both with regard to acoustic focus and with regard to the energy imparted by each member of the array, said control being mediated by temperatures sensing means (40) adjacent a tumor. This ultrasound unit may be associated with a heat treatment tank (51, 31) including a flexible membrane (32, 52) which may overlie a tumor, thereby to locally raise the temperature and reduce the amount of ultrasonic power required to achieve a desired temperature.

Abstract: A tele-diaphanography apparatus suitable for transilluminating human or animal tissues, which apparatus comprises a first housing including a source of light of wavelength from 300 Nm to 2000 Nm; means for directing light from the first light source onto the tissues to be examined by transillumination, and a heat-absorbing filter located in the path of the light from the light source; a second housing including a source of light of wavelength from 300 Nm to 2000 Nm, and means for directing the light from the second light source onto the tissues to be examined; a light detector for detecting the light transmitted through the transilluminated tissue being examined; a visual display unit for displaying the image detected by the light detector; and recording means for recording the image detected by the light detector.
