Myoballs were cultured from biopsies of adult human skeletal muscle. Transient currents through the sodium channels were elicited by depolarizing a myoball membrane with the whole-cell patch-clamp technique. The properties of the sodium channels were determined from the Hodgkin-Huxley parameters (INa max, tau m, tau h, h infinity-curve) derived from these transients. Halothane, when applied at 3.4 mmol/l (approximately 15 kPa), blocked about 50% of the current through the adult, TTX-sensitive sodium channels but had little effect on the current through the juvenile, TTX-insensitive sodium channels. At greater than 12 mmol/l, halothane blocked both channel types completely. The time constants of activation and inactivation were decreased in the presence of 3.4 mmol/l halothane but not enough to account for the decrease of the current amplitude. Halothane shifted the h infinity-curves of both channel types toward more negative potentials by an amount that was roughly proportional to its concentration. Myoballs from a man susceptible to malignant hyperthermia (MH) gave the same results as the controls indicating that the halothane effect on the action potential of MH-susceptible muscle are not mediated by a specific effect on the sodium channels.

The effects of different kinds of anesthesia on the function of live (evaluated on the basis of activity of enzymes -- aspartate aminotransferase, fructose-I-monophosphate aldelase and glutamate dehydrogenase) were studied in 63 infantile patients with Hodgkin's disease who underwent diagnostic laparotomy with splenectomy. It was found that during the first 6 days after surgery, the rate of activity of these enzymes shows a rise and reaches the upper limits in 77.8% of cases. Halothane anesthesia induced excessive enzymatic activity in 100%, while neuroleptanalgesia -- in 53.8% of cases. Repeated application of halothane produced a higher hepatotoxic effect as manifested by enhanced activity of glutamate dehydrogenase on days 1--2 after operation.
