OBJECTIVE:To study the compatibility of gatifloxacin for injection with famotidine for injection in 0.9% sodium chloride injection or 5% glucose injection.METHODS:At room temperature ((20?1)℃)for 8 hours,the changes of the mixture in appearance,pH and UV spectra were observed,and the contents of gatifloxacin and famotidine were determined by ultraviolet spectrophotometry.RESULTS:No significant change was found in pH values and contents within 8h after mixing of the two drugs,nor significant changes were found for the mixture in appearance within 8h in 0.9% sodium chloride injection or within 6h in 5% glucose injection.CONCLUSION: The mixture of gatifloxacin for injection and famotidine for injection were stable in 0.9% sodium chloride injection or 5% glucose injection.

OBJECTIVE:To study the compatibility of gatifloxacin for injection with etamsylate injection in 0.9% sodium chloride injection and 5% glucose injection.METHODS:The appearance of the mixture of gatifloxacin for injection with etams-ylate injection in 0.9% sodium chloride injection and 5% glucose injection at room temperature,i.e.(20?1)℃ within 8 hours was observed,with its pH measured and ultraviolet spectra observed.The contents of gatifloxacin and etamsylate were determined by a dual ultraviolet spectrophotometry.RESULTS:No significant change was noted for the mixture within 8 h in pH and appearance,and the contents of gatifloxacin and etamsylate within 8 h in 0.9% sodium chloride injection or within 6 h in 5% glucose injection showed no obvious change.CONCLUSION:Gatifloxacin for injection can be mixed with etamsylate injection in 0.9% sodium chloride injection or 5% glucose injection.

We had previously reported the height-weight formula for the estimation of body surface area of adult Chinese males (this journal 6(2):87, 1984). In this study, by using the same paper cast method, a formula for the adult Chinese females was obtained from the data of 44 healthy subjects (age 18-45) coming from 15 provinces. The mean body weight, height and surface area measured were 52.13?6.22 kg, 159.3?5.18 cm and 1.546?0.105 m2 respectively. The formula thus derived was: body surface area (m2) = 0.00586H (cm) +0.0126W (kg)-0.0461. The value calculated from it was 0.03% less than the value actually measured on an average. The percentage of various body regions to the total body surface area was as follows: head, 6.33; trunk (including neck), 28.27; upper arms, 8.29; forearms, 6.65; hands, 4.52; thighs (including buttocks), 27.40; calves, 12.83 and feet, 6.65.
