Ethylene oxide induces central-peripheral distal axonal degeneration of the lumbar primary neurones in rats.

Wistar rats subjected to a single exposure lasting six hours to ethylene oxide (EO) at a concentration of 500 parts per million three times a week for 13 weeks developed ataxia in the hindlegs. Myelinated fibres in hindleg nerves and in the fasciculus gracilis showed axonal degeneration sparing the nerve cell body of the lumbar dorsal root ganglion and myelinated fibres of lumbar dorsal and ventral roots. These pathological findings are compatible with central-peripheral distal axonal degeneration. This is the first animal model of EO neuropathy to be histopathologically verified.

Treatment of cryptococcal meningitis with pulmonary granuloma.

Two patients with co-existing meningeal and pulmonary cryptococcosis were successfully treated by pulmonary resection and chemotherapy. Under cover of miconazole and 5-fluorocytosine, pulmonary mass lesions were successfully removed despite the fact that the patients had meningitis. The patients recovered from meningitis immediately after the surgical procedures and show no recurrence of meningeal symptoms more than 2 years after the operation. It appears that early removal of a pulmonary cryptococcal focus combined with antifungal agents may give a quite favourable outcome for meningitis.

Comparative pharmacokinetics of dicloxacillin and ampicillin between individual and combined doses.

Pharmacokinetics of dicloxacillin and ampicillin dosed individually and in combination were investigated by means of moment analyses of urinary excretions of intact forms and metabolic products of parent penicillins. Comparison of excretion profiles between individual and combined doses to human subjects indicated that the transformation of ampicillin to penicilloic acid and subsequent conversion to secondary metabolite are suppressed by the simultaneous dose of dicloxacillin, while the total excretion ratio to dose and the mean residence times in the body remain almost unchanged. The excretion profiles of dicloxacillin and metabolites are not significantly affected by the combined dose.
