Abstract

Background and Objective: Free radical production andsubsqunt oxidative steress can be due to hyperglycemia and its oxidation. This study was done to evaluate the effect of swimming training test and Fenugreek seed extract on plasma glucose and antioxidant activity in heart tissue of streptozotocine – induced diabetic rats. Methods: In this experimental study, 50 male wistar rats were allocated into five groups diabetic (DC, n=10), healthy control (HC, n=10), swimming training (S, n=10), swimming training + Fenugreek seed extract (1.74 g/kg/bw) (SF1, n=10), and swimming training + Fenugreek seed extract (0.87 g/kg/bw) (SF2, n=10). Streptozotocine (60 mg/kg/bw) was used for induction of diabetes in DC, S, SF1 and SF2 groups. Serum glucose and the rat heart tissue antioxidant enzymes activities of superoxide dismutase, Catalase and Glutation peroxidase were determined. Results: Body weight in all groups were significantly reduced in comparsion with healthy control group (P<0.05). Plasma glucose level significantly reduced in SF1 and HC groups compared to diabetic group (P<0.05). Cardiac antioxidant enzymes in swimming training, SF1 and SF2 groups significantly increased in compare to diabetic group (P<0.05). Conclusion: The combination of endurance swimming training and fenugreek seed extract can reduce plasma glucose and increase cardiac antioxidant enzymes in streptozotocine – induced diabetic rats.

Abstract

Background and Objective: Pterygium is a fibrovascular lesion of the ocular surface with unknown origin, decrease in the vision. This study was done to evaluate the possible role of Epstein-Barr virus (EBV) in the formation of pterygia. Methods: This case-control study was done on 50 tissue specimens of pterygium from the patients who underwent pterygium surgery as the case group and 10 conjunctival biopsy specimens of individuals without pterygium including the patients whom underwent cataract surgery, as controls. The evidence of EBV infection was tested by polymerase chain reaction (PCR). Results: EBV was detected in three (6%) patients with pterygia. EBV was not detected in controls. There was not any significant correlation between pterygium and the presence of EBV. Conclusion: According to this study, EBV virus is not associated with pterygium formation.

Abstract

Background and Objective: The blood–brain barrier (BBB) is considered to be the main barrier to drug transport into the central nervous system. In this study, the capability of biopartitioning micellar chromatography (BMC) using the mixed micellar system of Brij-35/sodium dodecyl sulfate (Brij-35/SDS, 85:15 mol/mol) has been studied to predict pharmacokinetic parameter (BBB penetration ability) of 14 basic drugs.

Methods: In this descriptive-analytical study, the potential of BMC using mixed micellar system (Brij-35/SDS, 85:15 mol/mol) in 0.04 M at physiological pH 7.4 was evaluated to predict pharmacokinetic parameter (BBB penetration ability) of 14 basic drugs. The regression model for the prediction of blood-brain distribution coefficient is derived from the multiple linear regression analysis using the training set in mixed micellar mobile phase. Also, the predictive ability of model was evaluated for a prediction set of 5 compounds (Chlorpromazine, Mianserin, Propranolol, Cimetidine, and Thioridazine). The fair R2 indicates good stability and predictive ability of the developed model for the drugs not included in modeling.

Results: The relationship between the BMC retention data of 14 basic drugs and their log BB parameter showed a good statistically model (R2=0.822, F=25.42, SE=0.225, R2CV=0.781).

Conclusion: This study points out the usefulness of mixed micellar solution of Brij-35/SDS, 85:15 (mol/mol) in BMC as a high-throughput primary screening tool that can provide key information about the blood-brain distribution of basic drugs in a simple and economical way.

Abstract

Burn is one of the major causes of death and disability in the world. It can cause by heat, chemicals, electricity, sunlight or radiation. More burns caused by fires in buildings, contact with boiling water, steam, liquids and flammable gases. Accelerating the process of healing has always been of interest to practitioners because these injuries are usually takes long time to be healed. Therefore, proper treatment and care of this type of wound required to accelerate healing, prevent infection and chronicity. In traditional medicine, due to the high vegetation diversity and breadth of our country, the use of herbs for burns healing and lesions of various etiologies, has been intesified. Various studies on burn wound healing properties of medicinal plants have been performed. In this article, we refered to reliable sites for evaluating of 10 plants including Amebia euchroma, Green Tea, Hypericum perforatum, Centella asiatica, Scrophularia striata, Aloe vera, Cydonia Oblongae seeed, Malva sylvestris, Calendula officinalis and Myrtus to compare the restorative properties of a number of important medicinal plant flora of Iran on accelerating the process of wounds healing of burn in order to provide effective medicinal plant sources are addressed.

Abstract

Background and Objective: Population growth and pollution caused by the discharge of all kinds of urban, industrial, and agricultural sewage, leachate from landfills, and surface water runoff cause an increase in pollution of water sources. The entry of heavy metals into the environment, especially aquatic ecosystems, due to entering the food chain and jeopardizing human health is one of the concerns of society. This study was conducted to determine the level of heavy metals in muscles of Cynoglossus arel and Pomadasys kaakan fishes in Boushehr coastal waters, north of the Persian Gulf.
Methods: This descriptive study was conducted on twenty pieces of Cynoglossus arel and twenty pieces of Pomadasys kaakan fishes take place from three coastal stations of Boushehr, north of the Persian Gulf, Iran during spring of 2022. The samples were randomly selected from the fish market. After preparation, bioassay, and digestion of fish muscle by concentrated nitric acid, the concentration of heavy metals including nickel, zinc, copper, lead, and cadmium (µg/g) in the muscle tissue was measured by ICP-OES device. The concentration of heavy metals in the fish muscle tissue for human consumption was compared with international standards (FAO, WHO, FDA, NHMRC, and UKMAFF). According to the method of the US Environmental Protection Agency for fish consumption, daily absorption estimates and heavy metal risk indicators were calculated.
Results: The risk potential index for both species was less than one. The daily and weekly absorption of Cynoglossus arel (zinc > copper > nickel > lead > cadmium) and Pomadasys kaakan (copper > zinc > nickel > lead > cadmium) were determined. The mean concentration of heavy metals nickel, zinc, copper, lead, and cadmium in the muscle tissue of the studied species was determined to be 1.88±0.07, 27.16±8.11, 11.55±4.12, 1.14±0.06, and 0.19±0.03 µg/g, respectively. The highest amounts of studied metals in aquatic animals were zinc > copper > nickel > lead > cadmium. The concentration of metals in the analyzed samples was lower than the international standards.
Conclusion: Regarding toxicity, the concentration of metals in Cynoglossus arel and Pomadasys kaakan was evaluated as acceptable for human consumption. In addition, the amount of risk potential and risk index for non-cancerous diseases in adults and children in fish muscle tissue was less than 1, and the consumption of this fish does not cause any problems for human health.
