ABSTRACT
Objective To evaluate the characteristics of the haemodynamics of the hysteromyoma and its diagnosis value. Methods To apply the transvaginal color doppler ultrasound to detect the blood flow parameters of the uterine artery and the muscular tumor’s peripheral and inner area from 68 patients with hysteromyoma, compared with the blood flow parameters of the uterine artery from 50 normal women so as to analyze their difference. Results (1) In the hysteromyoma group, the maximum blood flow velocity during the systolic phase (SP) and the minimum blood flow velocity during the end-diastolic phase (ED) of uterine artery are significantly higher than those in the normal group(P
ABSTRACT
Objective To evaluate the value of transvaginal ultrasound in the diagnosis of tubal pregnancy.Methods The retrospective analysis was made according to transvaginal ultrasound inspection on 77 patients and their sonographic appearance and ultrasonic diagnosis of tubal pregnancy proved by surgery and pathology.Results The two-dimensional sonogram mainly showed the adnexal masses and the liquid area opaca in the pelvic cavity.The masses were divided into three types:germ heart-beat type,gestational sac type,and uneven mixed mass type.According to distinctive two-dimensional sonographic appearance,the accuracy rates of transvaginal ultrasound in the diagnosis of rupture,nonrupture,and abortion tubal pregnancy were 87.23%,100%,and 34.62%,respectively.In combination with pelvic mass,indirect sign of effusion,and patient history,the accuracy rates of ultrasonic diagnosis in the above clinical classifications were 95.74%,100%,and 84.61%,respectively.The accuracy rate of the total ultrasonic diagnosis was 92.21%.Conclusions Transvaginal ultrasound has higher accuracy in the diagnosis of rupture and nonrupture tubal pregnancy,but it lacks distinctive sonographic appearance in the diagnosis of the majority of abortion tubal pregnancy,which is the main reason for affecting the accuracy of ultrasonic diagnosis of tubal pregnancy.
ABSTRACT
Azone ( 1桪odeylazacyclohenptan-2-one) is one of the best skin penetration enhancers. It can increase the permeability of skin for some hydrophobic compounds, so that it is possible to be admi-nistrated through skin. The effects of Azone on permeability of skin of a-Asarone, Nicorandil and Nitroglycerin were studied by flow through diffusion cell with radioactivity tracer.The results showed that the different concentrations of Azone gave different enhancement. The penetration of the 3 drugs was enhanced about 1-fold by
