Research Excerpts

Overview

Krypton is a gaseous ventilation tracer and distributes similarly to air. It is not widely available and relatively expensive.

"81mKrypton is a gaseous ventilation tracer and distributes similarly to air, but is not widely available and relatively expensive."( Comparison of 81mKrypton and 99mTc-Technegas for ventilation single-photon emission computed tomography in severe chronic obstructive pulmonary disease.

Effects

ExcerptReferenceRelevance
"Krypton 81m has many advantages for paediatric lung imaging, although the proper interpretation of ventilation and perfusion lung scans requires the quantitative analysis of the steady state images and clearance curves.

Treatment

ExcerptReferenceRelevance
"Krypton treated eyes also demonstrated a higher prevalence of ILM wrinkling in eyes with POHS (3/12, 25%) than in eyes with AMD (2/19, 10.5%) but this difference was not significant."( Internal limiting membrane wrinkling after argon and krypton laser photocoagulation of choroidal neovascularization.

Pharmacokinetics

ExcerptReferenceRelevance
"The physical characteristics of krypton-81m makes it particularly suited for the study of right ventricular function, but its ultrashort half-life (13."( Measurement of right ventricular volumes from ECG-gated steady-state krypton-81m angiocardiography.

Compound-Compound Interactions

Krypton laser with different power densities combined with Nd:YAG laser peripheral iridotomy (LPI) was tested. The intraocular pressure, blood-aqueous barrier and inflammatory of anterior chamber as well as the therapeutic effect were examined.

ExcerptReferenceRelevance
"To compare the influence of krypton laser with different power densities combined with Nd:YAG laser peripheral iridotomy (LPI) on the intraocular pressure, blood-aqueous barrier and inflammatory of anterior chamber as well as the therapeutic effect."( [Comparison of different power-density krypton laser combined with Nd:YAG laser peripheral iridotomy].

"Using a laser flare cell meter and Goldmann tonometer, the level of aqueous protein, the number of cells in the anterior chamber and intraocular pressure of 31 patients (62 eyes) who underwent krypton laser with different power densities combined with Nd:YAG laser peripheral iridotomy were examined and recorded preoperatively and postoperatively."( [Comparison of different power-density krypton laser combined with Nd:YAG laser peripheral iridotomy].

"When krypton laser combined with Nd:YAG laser peripheral iridotomy is under consideration, relatively low power-density krypton laser is recommended because it can achieve the similar therapeutic effects as high power-density krypton laser but leads to less complications and a briefer recovery."( [Comparison of different power-density krypton laser combined with Nd:YAG laser peripheral iridotomy].

Bioavailability

Krypton laser beam was poorly absorbed by hemoglobin. Could perform photocoagulation more effectively in some lesions with subretinal hemorrhage.

ExcerptReferenceRelevance
" The effects on rate of absorption of distending the intestine by increasing intraluminal pressure from 0-1 to 5-7 cm H2O as well as of augmenting the rate of luminal perfusion of the 85Kr solution were also investigated."( The importance of the intestinal countercurrent exchanger for 85Kr absorption from the feline gut.

" Furthermore, it could perform photocoagulation more effectively in some lesions with subretinal hemorrhage, because the krypton laser beam was poorly absorbed by hemoglobin."( Krypton and argon laser photocoagulation effects in subretinal hemorrhage.
