0 引言 随着氟喹诺酮类药物在临床的广泛应用，有关其应用所致不良反应的报道也日趋增多，我们通过对1990／2003年我院氟喹诺酮类药物不良反应情况报告如下，供临床参考。     

Friction, capacitance and transepidermal water loss (TEWL) in dry atopic and normal skin

The biophysical properties of non-eczematous skin at three locations in atopics and non-atopics were characterized using non-invasive physical methods. Skin friction was measured with a newly developed sliding friction instrument, the degree of hydration with a capacitance meter (Corneometer CM 820), and the transepidermal water loss (TEWL) was determined using an Evaporimeter EP1. The areas examined (dorsum of the hand, volar forearm and lower back) showed lower values of friction and capacitance in the atopic patients than did corresponding sites in the normal controls. In most areas a significant correlation between friction and capacitance was found. The TEWL was increased in atopic skin, but TEWL seems to correlate neither to friction nor to capacitance.     

The pharmacokinetics of ondansetron after intravenous injection in healthy volunteers phenotyped as poor or extensive metabolisers of debrisoquine.

The pharmacokinetics of the 5-HT3 receptor antagonist ondansetron following an 8 mg i.v. dose were investigated in 12 subjects previously phenotyped with debrisoquine. Six subjects were poor metabolisers (debrisoquine metabolic ratios 29-131) and six were extensive metabolisers (debrisoquine metabolic ratios 0.45-3.4). There was no significant difference in AUC, Cmax, CL or t1/2 between the poor and extensive metabolisers. It is concluded that ondansetron clearance is not mediated exclusively by cytochrome P-450 2D6.     

Free tissue transfer for type III tibial fractures. Microsurgery in 19 cases.

We report 19 tibial fractures Types III B and C treated by free flaps. The fracture healed in 16 cases after 12 (3-54) months. In 3 cases a secondary amputation was carried out. Tibial malalignment or substantial shortening ensued in 1 case each. We conclude that coverage with free flaps, radical removal of dead bone, stable external fixation and transfer of vascularized bone may salvage the majority of Type III B and C tibial fracture with function superior to that after amputation.
