[EX Q]: Abstract: The characteristics of train-of-four recovery after atracurium or vecuronium were studied, under enflurane anaesthesia, and compared with those associated with tubocurarine-induced blockade. Ten patients each received vecuronium 0.1 mg kg-1, atracurium 0.5 mg kg-1 or tubocurarine 0.5 mg kg-1. Neuromuscular blockade was calculated as the percent depression of the first twitch, and was determined at the time of reappearance of the second, third and fourth twitches of the train-of-four. The pattern during recovery from blockade induced by the three neuromuscular blocking agents was similar, with T2, T3 and T4 reappearing at approximately 93%, 89% and 86% residual blockade, respectively. These results are different from those previously reported by Lee (1975) indicating that, under enflurane anaesthesia, the train-of-four count may give an incorrect estimate of the degree of neuromuscular blockade.

[EX Q]: Abstract: Measurement of serum angiotensin-converting enzyme (ACE) is extremely useful as an aid in the diagnosis and longitudinal evaluation of patients with sarcoidosis. We have detected a human serum ACE-inhibitor which affects the ACE level obtained by activity measurements. The effect of the inhibitor can be eliminated by a mere eight-fold dilution of the serum sample with physiologic saline. We recommend that serum ACE be performed with 1:8 dilutions of serum to eliminate the effect of the ACE inhibitor. The inhibitor has a MW above 50,000 daltons, and reversibility of inhibition by dilution appears to be ion dependent. Dialysis of an inhibitor-containing serum sample against saline causes the inhibition to become irreversible, allowing the distinction between alinearity of the assay vs an inhibitor effect when a serum has ACE activity greater than 50 units/ml. The source of the serum ACE-inhibitor remains to be determined.

[EX Q]: Abstract: The role in the pathogenesis of immune complex-mediated glomerulonephritis of C5 or some terminal complement component dependent upon C5 for activation was explored in a congenic strain of C5 sufficient (NSN) and C5 deficient (OSN) mice. When these mice were given daily injections of heterologous protein, horse apoferritin (HAF), there were profound differences between the strains in the development of glomerulonephritis and renal dysfunction. When NSN and OSN mice produced low levels of anti-HAF, NSN mice developed extensive glomerular deposits of HAF and immune reactants and a mild proliferative glomerulonephritis. In contrast, comparable OSN mice developed only trace mesangial localization of HAF and no glomerular lesions by light microscopy. When NSN and OSN mice produced high levels of anti-HAF, both strains had equivalent glomerular immune deposits; however, NSN mice developed a severe necrotizing and crescentic glomerulonephritis, while OSN mice had much less glomerular injury. Compared to OSN mice, these NSN mice also had much more severe tubulointerstitial injury, and significantly higher serum creatinine levels. Thus, in this experimental model, the absence of C5 resulted in reduced glomerular immune complex localization when there were small amounts of circulating immune reactants; and in markedly reduced glomerular leukocyte influx, necrosis and crescent formation, when large amounts of immune reactants have localized in glomeruli. These effects could be mediated by C5 (such as C5a) or by some terminal complement component(s) dependent upon C5 for activation.
