Advances in Controlled Clinical Inhalation Studies

Advances in managed scientific Inhalation experiences represents clinical paintings awarded on the third overseas Inhalation Symposium held 1991 in Hannover, FRG. The symposium lined the recent advancements during this box of study. the most pollution of curiosity have been acid aerosols, fog, and indoor toxins, whereas in regards to organic results, an emphasis used to be put on immunotoxicological and biochemical parameters.

12. Ab­ normal gait in a patient with hys­ terical weakness. The patient adopts a variety of histri­ onic postures which do not resemble those of any organic disease 43 WEAKNESS are being tested or the hamstrings tendons are felt to become taut while quadriceps power is examined. The simultaneous contraction of agonist and antagonist is observed only in hysteria or dystonia, and the latter can be distinguished on other grounds, discussed in later chapters. The second characteristic of hysterical weakness is the absence of counter pressure which is normally exerted during maximal contraction.

The effect of gamma efferent activity is to sensitize the spindle endings to a stretch stimulus because the non-contractile central portion of the nuclear bag fibre elongates when its polar regions contract and its contained receptors are deformed. The primary ending is thus given an initial base-line stretch or 'bias' by virtue of contraction of the intrafusal fibres so that it will respond more readily to any externally applied stimulus, such as direct stretch or a vibration wave. The gamma efferent system may therefore be regarded as a control of the sensitivity of the stretch reflex arc, which may be adjusted up or down by central influences.

It should be noted that the procedure is unsuitable for those patients whose pain is made much worse by a preliminary gentle extension of the leg compression of the cervical spinal cord with resulting quadriparesis. Pains caused by paroxysmal and synchronous neuronal discharge, like trigeminal neuralgia and lightning pains, usually respond well to 23 PAIN AND OTHER SENSATIONS anticonvulsant medication, carbamazepine (Tegretol) being the most effective drug. Certain pains are associated with, and perhaps perpetuated by, a depressive state.
