BACKGROUND Isoflurane, a common anesthetic for cardiac surgery, reduced myocardial contractility in many experimental studies, few studies have determined isoflurane's direct impact on the left ventricular (LV) contractile function during cardiac surgery. We determined whether isoflurane dose-dependently reduces the peak systolic velocity of the lateral mitral annulus in tissue Doppler imaging ...

The interest in the relationship between thyroid dysfunction and obesity is on the increase. This study compares the triiodothyronine-to-thyroxine (T3/T4) ratio in obese and lean children and adolescents, and correlates thyroid hormones with body mass index (BMI) in obese Nigerian children. It is a retrospective study of records of 76 obese children and adolescents with a BMI of 31.7 ± 0.1 kg/m...

Previous studies have demonstrated that short-term treatment with peroxisome proliferators decreased the size and number of gamma-glutamyl transpeptidase or placental glutathione S-transferase (GSTP)-positive hepatic hyperplastic lesions. In this study, we have examined the effect of the hormone triiodothyronine (T3), which, similarly to peroxisome proliferators, is a strong liver mitogen and a...

Because little has been published on early effects of treatment with amiodarone on thyroid function, we studied serum total and free thyroid hormone, reverse T3, and TSH levels in patients with cardiac arrhythmias during the first 10 days of treatment with a loading dose of amiodarone by iv infusion. Twenty-four patients were enrolled in the study. A standardized loading regimen for the i.v. in...

objective(s) achillea genius is widely used in traditional medicine for gastrointestinal disorders. the aim of this study was to investigate the effects of aqueous-ethanol extract of achillea wilhelmsii on rat’s gastric motility in basal and vagal stimulated conditions. materials and methods twenty four wistar rats were randomly divided into two groups: control and test. the extract was prepare...

The current study aimed to investigate the anti-oxidative effects of Lipidum sativum agonist poisonous mercuric chloride. Total 60 Swiss male rats were used which allocated into 5 groups; control group (C), chloride (M), third, fourth and fifth groups represented treatment (T1, T2 & T3), each was divide two subgroups (21 42 days. blood samples collection by heart puncture for Hematological ...

This study was carried out to investigate the effects of intraruminal infusion of propionate on ruminal fermentation characteristics and blood hormones and metabolites in Hanwoo (Korean cattle) steers. Four Hanwoo steers (average body wt. 270 kg, 13 month of age) equipped with rumen cannula were infused into rumens with 0.0 M (Water, C), 0.5 M (37 g/L, T1), 1.0 M (74 g/L, T2) and 1.5 M (111 g/L...

Thyroid acting through ligand binding to nuclear receptors modifies myocardial respiratory kinetics and oxidative phosphorylation in the heart. Direct nongenomic action of thyroid hormone on high-energy phosphate concentrations and respiratory kinetics has never been proven in vivo but might be responsible for observed changes in oxygen utilization efficiency immediately after triiodothyronine ...

Abstract The study employed 300 laying hens at 34 weeks of age, divided into 5 treatments with 3 replicates per replication 20 birds each, to determine the impact adding okra powder and vitamins C E (Brown-Lite Lohman) egg broiler diets on certain qualitative features oxidation indicators. were: (T1): control treatment without any addition, (T2) 250 mg vitamin / kg diet, (T3) 200 (T4) 2 gm (T5)...
