Evaluating the role of polysaccharide extracted from Pleurotus columbinus on cisplatin-induced oxidative renal injury.

This research aimed to examine the antioxidant polysaccharide activity (PsPc-3) derived from Pleurotus columbinus (P. columbinus) on oxidative renal injury (ORI) induced by cisplatin (CP). The principal components of crude polysaccharide were assessed.

Evaluating the role of propolis and bee venom on the oxidative stress induced by gamma rays in rats.

Honeybee products consist of many substances, which have long been known for their medicinal and health-promoting properties. This study set out to appraise the protective potential of Egyptian propolis (EP) and bee venom (BV) separately or combined against total body irradiation (TBI) induced oxidative injury in rats. Besides, we assessed the bioactive components in EP and BV using HPLC and UPLC/ ESI-MS analysis in the positive ion mode.

Assessment role of total phenols and flavonoids extracted from Pleurotus columbinus mushroom on the premature ovarian failure induced by chemotherapy in rats.

Background: Many species of mushroom contain an assortment of free radical scavengers (Phenolics and Flavonoids compounds) that have made them nutritionally beneficial and a source of expansion of drug production. In this study, we examined the preventive and remedial role of total phenol extract from Pleurotus columbines (TP) in alleviating the consequences of cyclophosphamide (CTX) on the ovaries of female rats. Rats were randomly assigned to four groups: healthy controls, cyclophosphamide (CTX), received a TP (100 mg/kg) orally daily for 14 days and curative group: CTX-TP, we determined and identified a total phenol from a mushroom extract and examined it as an antioxidant agent.

Effects of extracts on the testicular measurements, genomic DNA and antioxidant enzymes in irradiated rats.

Background: Oxidative stress and reactive oxygen species (ROS) are primarily responsible for the development of male infertility after exposure to γ-irradiation. The present work aimed to assess the ameliorative and therapeutic roles of the aqueous and ethanolic extracts of the edible seaweed () on spermatogenesis and infertility in γ-irradiated Wistar rats.

Materials And Methods: Induction of infertility was performed by exposing the rats to Cs-gamma rays, using a single dose of 3.

Effects of silver nanoparticles-polysaccharide on bleomycin-induced pulmonary fibrosis in rats.

Objectives: The first goal of this study was to synthesize the silver nanoparticles Alcaligenes xylosoxidans exopolysaccharide (Ag-AXEPS). The second objective was to analyse the role of Ag-AXEPS nanoparticles (NPS) in treating bleomycin (BLM)-induced lung fibrosis.

Methods: Intratracheal bleomycin (2.

Study of the chemical structure of exopolysaccharide produced from streptomycete and its effect as an attenuate for antineoplastic drug 5-fluorouracil that induced gastrointestinal toxicity in rats.

Chemotherapeutic medications, including 5 - fluorouracil (5FU), are the same old technique to most cancers and are associated with numerous peripheral toxicities. We investigated exopolysaccharide (EPSST) produced from the isolated streptomycete of the Mediterranean Sea for the capability to lower the severity of mucositis . The streptomycete was isolated from Mediterranean Sea sediment from the beaches of Port Said Governorates, Egypt and identified morphologically, physiologically, and biochemically and confirmed by molecularly 16S rDNA analysis.

Evaluation of the therapeutic effects of rice husk nanosilica combined with platelet-derived growth factor in hepatic veno-occlusive disease.

Veno-occlusive disease is an important pattern of hepatotoxicity associated with antineoplastic drugs. The study investigated the possible therapeutic effects of RHS nanoparticles combined with a PDGF on veno-occlusive disease (VOD) in liver elicited in rats with DAC. In this work, nanosilica (SiO) was successfully prepared from rice husk, and its physicochemical characteristics were investigated using EDX, XRD, N adsorption-desorption isotherm, SEM, and TEM.

Effect of polysaccharide from Bacillus subtilis sp. on cardiovascular diseases and atherogenic indices in diabetic rats.

Background: Diabetes mellitus induces chronic complications such as cardiovascular damage, cataracts and retinopathy, nephropathy, and polyneuropathy. The main aim of the study was to isolate and identify both of bacterial strain and exopolysaccharide to assess the possible efficiency of exopolysaccharide (BSEPS) from Bacillus subtilus sp .suppress on cardiovascular diseases, atherogenic and coronary risk indices in diabetic rats.

Protective Effect of Adansonia digitata against Isoproterenol-Induced Myocardial Injury in Rats.

The baobab fruit (Adansonia digitata) was analyzed for proximate composition, amino acids, and minerals. The fruit pulp was found to be a good source of carbohydrates, proteins, phenols, and substantial quantities of K, Ca, and Mg. Amino acid analyses revealed high glutamic and aspartic acid, but the sulfur amino acids were the most limited.

The anti-ulcerative colitis effects of Annona squamosa Linn. leaf aqueous extract in experimental animal model.

This study aimed to evaluate the anti-inflammatory effects of Annona squamosa (A. squamosa) leaf aqueous extract against acetic acid induced colitis in rats with a trial to explore its use for the treatment of colon inflammation. Sprague Dawley rats weighing 180-200 g were used in this study.

Efficiency of calcium phosphate composite nanoparticles in targeting Ehrlich carcinoma cells transplanted in mice.

The present study aimed to investigate the mode of action of nano-CaPs in vivo as a therapy for solid tumor in mice. To achieve this goal, Ehrlich Ascites Carcinoma (EAC) was transplanted into 85 Swiss male albino mice. After nine days, the mice were divided into 9 groups.

Efficacy of polysaccharide from Alcaligenes xylosoxidans MSA3 administration as protection against γ-radiation in female rats.

Damage to normal tissues is a consequence of both therapeutic and accidental exposures to ionizing radiation. A water-soluble heteropolysaccharide called AXEPS, composed of glucose, galactose, rhamnose and glucouronic acid in a molar ratio of nearly 1.0:1.

Evaluation of mesenchymal stem cells in treatment of infertility in male rats.

Introduction: The present study aimed to elucidate the therapeutic effects of mesenchymal stem cells (MSCs) derived from the bone marrow of rats (BM) against toxic effects of lead (Pb) on the male gonads of experimental rats.

Methods: The experimental animals were exposed to lead in the form of lead nitrate (LN) one quarter of the LD50. The efficacy of MSCs to reduce gonado-totoxicity induced by lead nitrate at 21, 30 and 60 days, was evaluated experimentally in male rats.
