| vestibular blind sac | <anatomy> The lower extremity of the cochlear duct, occupying the cochlear recess in the vestibule. Synonym: caecum vestibulare, vestibular blind sac. (05 Mar 2000) |
|---|---|
| cupular blind sac | The upper blind extremity of the cochlear duct. Synonym: caecum cupulare, cupular blind sac, lagena. (05 Mar 2000) |
| prospective, randomised, double-blind clinical trial | <statistics> A clinical trial in which the method for analysing data has been specified in the protocol before the study has begun (prospective), the patients have been randomly assigned to receive either the study drug or alternative treatment, and in which neither the patient nor the physician conducting the study know which treatment is being given to the patient. (13 Nov 1997) |
| single-blind method | A method in which either the observer(s) or the subject(s) is kept ignorant of the group to which the subjects are assigned. (12 Dec 1998) |
| double-blind | <statistics> A kind of clinical study in which neither the participants nor the person administering treatment know which treatment any particular subject is receiving. Usually the comparison is between an experimental drug and a placebo or standard comparison treatment. This method is believed to achieve the most accuracy because neither the doctor nor the patient can affect the observed results with their psychological bias. (10 Oct 1997) |
| double-blind experiment | <statistics> An experiment conducted with neither experimenter nor subjects knowing which experiment is the control; prevents bias in recording results. See: double-masked experiment. (05 Mar 2000) |
| double-blind method | <statistics> A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment. (12 Dec 1998) |
| double-blind study | A study in which neither the experimenter nor any other assessor of the results, including patients, know which group is subject to which procedure, thus helping assure that the biases or expectations of either will not influence the results. (05 Mar 2000) |
| afferent loop syndrome | <syndrome> A complication of gastrojejunostomy, caused by acute or chronic obstruction of the afferent loop due to hernia, intussusception, kinking, volvulus, etc. It is characterised by pain and vomiting of bile-stained fluid and includes acute afferent loop obstruction and bilious vomiting. (12 Dec 1998) |
| arch-loop-whorl system | See: Galton's system of classification of fingerprints. (05 Mar 2000) |
| Biebl loop | A continuous loop of small intestine brought through the abdominal wall to a subcutaneous location, for observation of motility. (05 Mar 2000) |
| bulboventricular loop | The portion of the early-somite embryonic cardiac tube that evolves into the ventricle and bulbus cordis. Synonym: ventricular loop. (05 Mar 2000) |
| gamma loop | The reflex arc consisting of small anterior horn cells and neuroma, their small fibres projecting to the intrafusal bundle producing its contraction, which initiates the afferent impulses that pass through the posterior root to the anterior horn cells, inducing a stretch reflex. Synonym: gamma motor neurons, gamma motor system, Granit's loop. (05 Mar 2000) |
| vector loop | <physiology> An irregular, usually elliptical, curve representing the average direction and magnitude of the heart's action from moment to moment throughout the cardiac cycle. See: vector, vectorcardiogram. (06 Mar 2000) |
| gastrojejunal loop obstruction syndrome | <syndrome> A complication of gastrojejunostomy, caused by acute or chronic obstruction of the afferent loop due to hernia, intussusception, kinking, volvulus, etc. It is characterised by pain and vomiting of bile-stained fluid and includes acute afferent loop obstruction and bilious vomiting.
