| intra-aortic balloon pumping | Counterpulsation in which a pumping unit synchronised with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion. (12 Dec 1998) |

| laser-assisted balloon angioplasty | <cardiology, procedure> Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1. Laser fibre delivering the energy while the inflated balloon centres the fibre and occludes the blood flow. 2. Balloon angioplasty immediately following laser angioplasty. 3. Laser energy transmitted through angioplasty balloons that contain an internal fibre. (05 Mar 2000) |
| absorptive cells of intestine | Cell's on the surface of villi of the small intestine and the luminal surface of the large intestine that are characterised by having microvilli on their free surface. (05 Mar 2000) |
| air cells | Air-containing spaces in the skull. See: pulmonary alveolus. (05 Mar 2000) |
| air cells of auditory tube | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| Alpha cells | Alpha cell's of pancreas or of anterior lobe of hypophysis. (05 Mar 2000) |
| alpha cells of anterior lobe of hypophysis | Acidophil cell's that constitute about 35% of the cell's of the anterior lobe. There are two varieties: one that elaborates somatotropin, another that elaborates prolactin. (05 Mar 2000) |
| alpha cells of pancreas | Cell's of the islets of Langerhans that secrete glucagon. (05 Mar 2000) |
| amniogenic cells | Cell's from which the amnion develops. (05 Mar 2000) |
| anabiotic cells | Cell's that are capable of resuscitation after apparent death; the existence of anabiotic tumour cell's is postulated to explain the recurrence of a cancer after a very long symptomless period following operation. (05 Mar 2000) |
| angioblastic cells | Those cell's in the early embryo from which primitive blood cell's and endothelium develop. (05 Mar 2000) |
| anterior cells | The anterior group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales anteriores, anterior cells, anterior sinuses, cellulae anteriores. (05 Mar 2000) |
| anterior ethmoidal air cells | The anterior group of air cells of the ethmoidal sinus's; each sinus communicates with the middle meatus of the nasal cavity. Synonym: sinus ethmoidales anteriores, anterior cells, anterior sinuses, cellulae anteriores. (05 Mar 2000) |
| anterior horn cells | Motor neurons in the anterior (ventral) horn of the spinal cord which project to skeletal muscles. (12 Dec 1998) |
| antibody-producing cells | Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesise. (12 Dec 1998) |
