In order to investigate the effects of acute CO poisoning and subsequent oxygen therapy on cardiac necrosis in rats, with a specific focus adiponectin levels, twenty–one male Wistar albino rats were divided into three groups (Control, CO, CO+O2). The Control group was placed container exposed room air for 30 min. Acute induced CO+O2 by exposing gas Following exposure, received min, while did not receive any additional intervention. animals euthanized puncture under anesthesia, following...

Abstract Statin treatment may increase the risk of diabetes; there is insufficient data on how statins affect glucose regulation and glycemic control effects liver enzymes related to carbohydrate metabolism have not been fully studied. Therefore, we aimed compare statin derivatives, pravastatin, rosuvastatin, in an experimental diabetic rat model. Female Wistar albino rats were used diabetes was induced by intraperitoneal injection streptozotocin. Thereafter, 10 20 mg kg −1 day doses both...

In the present study, coumarin and some derivatives (esculetin, scoparone, 4-methylumbelliferone) were investigated for their lipid-lowering effect in rats. Male Sprague–Dawley rats (150–200 g) divided into six groups each group comprised of five Hepatic injury-dependent hyperlipidemia was induced by carbon tetrachloride (CCl 4 , 1.25 ml/kg). Coumarin esculetin (35 mg/kg), scoparone 4-methylumbelliferone or (30 mg/kg) administered to experimental at 12-h intervals. Animals received...

Acute carbon monoxide (CO) poisoning may cause liver damage and dysfunction. Therefore, in this study, we aimed to compare the efficiency of normobaric oxygen (NBO) high-flow nasal cannula (HFNCO) treatments on injury. For that purpose, 28 male Wistar albino rats were divided into four groups (Control, CO, CO + NBO, HFNCO). The control group was allowed breath room air for 30 min. HFNCO induced by exposure Thereafter, NBO received 100% with reservoir mask through At end experiment, all...

Horses that become fatigued either stop exercising or continue but at a lower intensity. The researches show there are many causes of exercise induced fatigue. depletion energy stores and accumulation metabolites during muscle contraction considered as the important factors causing Furthermore, generated heat impairs fluid, electrolyte acid-base balances internal environment horse body. occurrence physiological fatigue differs according to type is performing. intensity duration very...

The effect of maternal undernutrition on muscle development near-term ovine fetuses was studied in 2 experiments. In each experiment, Welsh mountain ewes were randomly assigned to either control (C) or nutrient-restricted (R) groups. the first mild (85% daily nutritional requirement (DNR)), and second severe (50% DNR), imposed between 0 70 days gestation (dg). Controls for both groups maintained 100% their DNR throughout experiment. killed at 126 ± 1 dg by an intravenous injection...

Neither drugs given intravenously--phentolamine, propranolol, atropine and naloxone--nor vagotomy were able prevent somatostatin-induced inhibition We conclude that secretion is not dependent on intact...

Some scientific evidence indicates that antioxidant-rich diets may prevent the negative effects of free radicals. In this study, we aimed to evaluate kefir consumption on paraxonase-1 (PON1) activity, total antioxidant status (TAS), oxidant (TOS), and serum lipid parameters in smokers non-smokers. At baseline, PON1 TAS, high-density lipoprotein cholesterol (HDL-C) levels were lower (P<0.05, P<0.01, P<0.05, respectively) whereas TOS, triglyceride (TG), light-density (LDL-C) higher (all...

<title>Abstract</title> Statins may affect glucose metabolism through adipokines. The aim of this study was to measure the effects hydrophilic statins on some adipokine levels in diabetic rats. Wistar albino rats were divided into four groups: healthy control, untreated diabetic, treated with pravastatin, and rosuvastatin. Diabetes induced by intraperitoneal injection streptozotocin. Thereafter, 20 mg/kg/day doses either pravastatin or rosuvastatin administered for eight weeks. At end...

Many stabled horses perform a variety of stereotypic behaviours such as cribbing, circling, wall kicking, self-mutilation, weaving and headshaking. It is difficult to know why exactly each horse performs these behaviours, there may be specific causal factors for activities in the horse. Homeopathy can contribute treatment disorders, because it approaches organism sum characteristics an animal when state health or illness, at physical, mental psychological level.
