Preliminary evaluation of haemostatic and wound healing potential of Heliotropium europaeum.

Heliotropium europaeum has been traditionally used to stop bleeding and accelerate scarring. This study provides a scientific evaluation of H. europaeum haemostatic and healing potential.

Nephrotoxicity in Hybrid sparrow (Passer domesticus × Passer hispaniolensis) living near a phosphate treatment factory complex in southern Tunisia: a biochemical and histological study.

Our study was designed to evaluate impacts of exposure to pollutants, released by the Gabès-Ghannouche factory complex of phosphate treatment, on biochemical biomarkers and histopathological indices in kidney tissues of Hybrid sparrow (Passer domesticus × Passer hispaniolensis) in Gabès city. Our results show evidence of a pronounced impairment in kidney function which is confirmed by remarkable blood chemical alterations in sparrows living in Ghannouche, the most polluted site. Moreover, superoxide dismutase and catalase activities were found to be decreased in birds sampled from the contaminated site when compared to less polluted areas.

Sulphated polysaccharide isolated from Sargassum vulgare: Characterization and hypolipidemic effects.

A sulphated polysaccharide from brown algae Sargassum vulgare (SVSP) was extracted and examined with respect to chemical, structural characterization and hypolipidemic effects. SVSP consisted mainly of sulphate and total sugars with low levels of lipids and proteins. Its structure was studied by nuclear magnetic resonance (RMN), gas chromatography-mass spectrometry (GC-MS), infra-red spectroscopic, differential scanning calorimetry and X-ray diffraction analysis.

Anti-obesity effect and protection of liver-kidney functions by Codium fragile sulphated polysaccharide on high fat diet induced obese rats.

The present study investigates the hypolipidemic effects of sulphated polysaccharide obtained from Codium fragile (CFSP) in induced obese rats (HFD). The results showed an increase in body weight of HFD rats by 21.56% as compared to control normal rats.

Effects of Cymodocea nodosa extract on metabolic disorders and oxidative stress in alloxan-diabetic rats.

This new study aimed to evaluate for the first time the effect of Cymodocea nodosa extract (CNE) on α-amylase activity, hyperglycemia and diabetes complications in the alloxan-induced diabetic rats. The in vitro evaluation and oral administration of CNE to surviving diabetic rats inhibited key enzyme related to hyperglycemia as α-amylase, helped to protect the β cells of the rats from death and damage confirmed by oral glucose test tolerance (OGTT), which leads to decrease in blood glucose level by 49% as compared to untreated diabetic rats. The CNE also decreased the triglyceride, low density lipoprotein (LDL) cholesterol and total cholesterol rates in the plasma of diabetic rats by 46%, 35%, and 21%, respectively, and increased the high density lipoprotein (HDL) cholesterol level by 36%, which helped maintain the homeostasis of blood lipid.

Inhibitory activities of Cystoseira crinita sulfated polysaccharide on key enzymes related to diabetes and hypertension: in vitro and animal study.

The present study investigated the effect of the Cystoseira crinita sulfated polysaccharide (CCSP) on key enzymes activities related to diabetes in vitro and in diabetic rats. We found that CCSP inhibited pancreatic α-amylase with IC = 39.16 μg/ml and angiotensin I-converting enzyme (ACE) activity with IC=58.

Inhibitory effects of Cymodocea nodosa sulphated polysaccharide on α-amylase activity, liver-kidney toxicities and lipid profile disorders in diabetic rats.

This study aimed to evaluate for the first time the effects of Cymodocea nodosa sulphated polysaccharide (CNSP) on the α-amylase activity, hyperglycaemia, liver-kidney functions, and pancreatic architecture of alloxan-induced diabetic rats. Animals were allocated into four groups of seven rats each, the body weight and blood glucose levels were estimated periodically for 2 months of treatment by gastric gavages route. The CNSP effect was confirmed by biochemical procedures and histological study.
