枢复宁在肺癌患者体内的药物动力学和生物利用度

９名接受顺铂化疗的原发性肺癌患者单次口服和静脉注射枢复宁８ｍｇ后，用反相高效液相色谱法测定血浆药物浓度。经用ＰＫＢＰ－Ｎ１程序在计算机上拟合计算表明，枢复宁在人体内表现为二房室模型。口服后主要药动学参数：Ｔ１／２Ｋａ＝０．４１±０．３０ｈ，Ｔ１／２α＝０．９±０．４３ｈ，Ｔ１／２β＝３．３±１．２ｈ，Ｃｍａｘ＝２８．６±９．５ｎｇ／ｍｌ，Ｔｍａｘ＝１．７±０．９ｈ，ＡＵＣ＝１５８±７３ｎｇ·ｈ／ｍｌ，绝对生物利用度为５５％。     

Ultrasound Biomicroscopic Dark Room Provocative Test

Purpose : To compare the clinical application value of Ultrasound biomicrsocpic dark room provocative test with the traditional dark room test in screening primary angle closure glaucoma (PACG).Methods: 22 eyes with PACG in prodromal stage and 30 eyes with deep anterior chamber and wide angle of 15 normal persons were observed in this trail. All 52 eyes were performed traditional dark room provocative test and ultrasound biomicorosopic darkroom test respectively. With different positive diagnostic criteria, the sensitivity of the two methods were compared using chi-squared analysis.Results : After staying in the dark room for 2 hours, In case group, IOP in 10 of 22 eyes rose more than 1. 07kPa(1kPa = 7.5mmHg), in 12 eyes less than 1.07kPa or had no changes; appositional angle closure were found by Goldmann gonioscopy in 8 eyes : 3 eyes in two quadrants, 5 eyes in more than two quadrants; the appositional angle closure was found by UBM in 15 eyes; 3 eyes in one quadrants, 5 eyes in two quadrants, 7 eyes
