1.	Ganglion Cysts (Ganglion) 03/01/1970 - "This response also resists ganglion-block and is highly sensitive to dimethyltubocurarine.6. It is suggested that in the normal conscious animal the nictitating membrane is held retracted by a relatively small amount of sympathetic activity, and that its protrusion is an active mechanism under voluntary control mediated by the striated muscles of the orbit.7. The importance of these mechanisms in the interpretation of experiments in which the nictitating membrane is used are discussed." 03/01/1970 - "1. When the movement of the nictitating membrane is recorded in the usual way, pulled out under load in cat, dog, or rabbit, end-plate-depolarizing drugs such as succinylcholine, decamethonium, nicotine, and 2268F, cause a retraction.2. This movement is due to activation of orbital striated muscle, as evidenced by the resistance of the movement to ganglion block or excision of the superior cervical ganglion and to administration of phentolamine or atropine, and by its great sensitivity to dimethyltubocurarine.3. End-plate-depolarizing drugs produce contractions of the superior and inferior oblique and of the recti muscles strong enough to account for the movements of the nictitating membrane, provided the known fascial connexions of the orbit allow transmission of a fraction of the extraocular muscle movement to the membrane.4. In post mortem specimens with the front of the orbit undisturbed, retraction of the central end of any of the ocular muscles produces movement of the nictitating membrane; the movement was greatest with the superior oblique and medial rectus. " 10/01/1974 - "Transmural stimulation with 1-50 pulses (0.2-0.4 ms at 10 Hz) elicited graded twitches which were abolished by tetrodotoxin and were therefore neurogenic; longer pulses sometimes triggered tetrodotoxin-resistant myogenic contractions.2 Twitches elicited by 0.2-0.4 ms pulses were due to post-ganglionic excitation because they were not reduced by hexamethonium, pentolinium or dimethyltubocurarine, or by ganglion-paralyzing concentrations of nicotine.3 The acetyl- and butyryl-cholinesterase activities of the rectococcygeus were determined manometrically and could be selectively inhibited by BW 284C51 (1:5-bis-(4-allyl-dimethylammonium-phenyl)-pentan-3-one dibromide) and iso-OMPA (tetramonoisopropylpyrophosphortetramide), respectively. " 05/01/1970 - "With trains of ten or more pulses, response A is always larger than B; the ratio of A/B (1.2-21.3) is subject to animal variation.2. Both responses are abolished by tetrodotoxin and are absent from plexus-free preparations.3. Neither response is reduced by ganglion-block with (+)-tubocurarine, dimethyltubocurarine or hexamethonium, or by ganglion-paralysing doses of nicotine; the contribution of excited preganglionic endings to these responses is therefore negligible.4. Neither response is due to a release of histamine, 5-hydroxytryptamine (5-HT) or prostaglandins, since both A and B persist in the presence of mepyramine, methysergide and the prostaglandin-antagonist SC-19220 (1-acetyl-2(8-chloro-10,11-dihydrodibenz [b,f] [1,4]oxazepine-10-carbonyl) hydrazine).5. The two response-components are affected differentially by a number of drugs.6. Histamine, 0.1 mug/ml., reduces response A to the level of B; this selective inhibition of the histamine-sensitive component in A is specifically antagonized by nicotine, 1-2.5 x 10(-5) g/ml.7. 5-HT, 0.1 mug/ml., and strychnine, 20-40 mug/ml., also reduce response A to the level of B, but these selective inhibitions are not antagonized by nicotine.8. Diphenhydramine, 10 mug/ml., produces equality of the two responses by depressing A and potentiating B.9. The inhibitory effects of the foregoing drugs are not due to catecholamine release, since they persist after alpha + beta adrenoceptor blockade with phentolamine and pronethalol, and after previous reserpinization of the guinea-pigs.10.

Wounds and Injuries (Trauma) 05/01/1984 - "The neuromuscular effects of the combined administration of pancuronium and dimethyltubocurarine were evaluated in children undergoing reconstructive surgery (n = 6), or the skin grafting of acute burn wounds: body surface area (BSA) burns less than 40% (n = 5); and BSA burns greater than 40% (n = 6).

3.	Tachycardia (Tachyarrhythmias) 03/01/1978 - "To examine the basis of tachycardia seen clinically with some neuromuscular blocking agents, the potencies of d-tubocurarine, dimethyltubocurarine, gallamine, and pancuronium in antagonizing the effects of vagal stimulation on the guinea pig atrial pacemaker were determined and expressed as an ED50 for vagal blockade.
