Background: Control of bleeding during dacryocystorhinostomy (DCR) surgery is of particular importance and controlling the body's hemodynamic responses to stress effectively reduces the amount of bleeding during surgery and improves the surgical area. Therefore, in this study, we aimed to investigate the effect of two-drug combinations Labetalol-Hydralazine and Labetalol-Trinitroglycerin on hem...

Trinitroglycerin (TNG) is an industrial chemical mostly known for its clinical use in treating angina and manufacturing dynamite. The wide manufacture and application of TNG has led to contamination of vast areas of soil and water. The present study describes degradation of TNG with zero-valent iron nanoparticles (ZVINs) in water either present alone or stabilized on nanostructured silica SBA-1...

Objective(s):To evaluate the effect of trinitroglycerin (TNG) as nitric oxide donor agent on serum copper (Cu) and zinc (Zn) levels and liver enzymes in BALB/c mice infected with Leishmania major (L. major) MRHO/IR/75/ER. Materials and Methods: Inbred female mice were divided into three groups: healthy group (uninfected naive mice), control group (infected with L. major), and test group (L. maj...

The carotid sinus baroreceptor reflex was studied in 11 normotensive subjects, using a variable pressure neck chamber and correcting for imperfect pressure transmission to the carotid sinus. Decreased carotid baroreceptor stimulation caused a sustaineded rise in arterial pressure, and increased carotid baroreceptor stimulation caused a sustain fall. The responses were in linear relation to the ...

We believe that the pattern of blood pressure response to tilt during the time preceding the development of the vasovagal reaction may provide adjunctive diagnostic information. A group of 101 consecutive patients affected by syncope of uncertain origin underwent passive tilt testing for 45 min at 60 followed, if negative, by oral (sublingual) trinitroglycerin (TNG) 0·4 g with continuation of t...

103 The Editor, A 27‐year‐old male professional bodybuilder presented with excruciating retrosternal chest pain, extending to his neck and shoulder. He gave a history of taking traditional medication (containing opium) for the pain that was self‐prescribed but the pain did not subside with that treatment, and his general physician referred him for cardiac evaluation in the emergency department....
