conclusions our method provided good results and performing evacuation under the guide of bedside ultrasonography is recommended. results we treated 173 patients, including 164 females (94.8%), with the mean (sd) age of 43.75 (10.62) years. according to vas, 95.4% of patients reported complete satisfaction while 2 (1.2%) were unsatisfied with the results. patients reported no complication of th...

topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. the new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. the adhesive capacity of hydroxypropyl methylcellulose (hpmc) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling tester. ...

Three dimensional gels of native type I collagen fibres have been used as a substratum for the growth and migration of Chinese hamster ovary cells (fibroblastoid cell line) and RPMI-3460 melanoma cells (tumorigenic cell line from Syrian hamster). Quantitative data concerning the migration of these cells from the gel surface into the 3-dimensional collagen gel matrix have been obtained. The migr...

We nave investigated the changes occurring in the pattern of translatable mRNA species in germ cells during spermatogenesis of mice. Highly homogeneous cell populations of spermatocytes or spermatids were purified. Poly(A) + mRNA was isolated from each cell population by oligo(dT)-cellulose chromatography. A comparison of meiotic and post-meiotic mRNAs was made by two-dimensional gel analyses o...

mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. carbomers are among the best mucosa-adhesive materials known. the aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing carbomers, either alone or in combination, to the data obtained from assessing the d...

Density gradient fractions prepared from healthy or scrapie-infected hamster brain tissue enriched in plasma membrane vesicles were treated with nucleases prior to phenol extraction and ethanol precipitation. The recovered nucleic acids were 3' end-labelled and run on one-dimensional polyacrylamide gels. Autoradiography revealed the presence of low molecular weight RNAs (4S) in both healthy and...

We describe a blue native polyacrylamide gel electrophoretic technique that allows the facile detection, quantitation and purification of three NADPH-producing enzymes. Glucose 6-phosphate dehydrogenase, malic enzyme and NADP-dependent isocitrate dehydrogenase were detected simultaneously. Activity staining based on the formation of NADPH from the respective substrates and the subsequent precip...
