Green Synthesis of Silver Nanoparticles via Black and Green Tea and Study its Toxicity on few Vital Organs of Female Mice
...Show More Authors

This study included synthesizing silver nanoparticles (AgNPs) in a green method using AgNO3 solution with glucose exposed to microwave radiation. The prepared NPs were also characterized using ultraviolet and visible (UV-vis) spectroscopy and scanning electron microscopy (SEM). The UV/vis spectroscopy confirmed the production of AgNPs, while SEM analysis showed that the typical spherical AgNPs were 30 nm and 50 nm in size for the NPs prepared using black tea (B) and green tea (G) as reducing agent, respectively. The changes in some of the biochemical parameters related to the liver and kidneys have been analyzed to evaluate the probable toxic effects of AgNPs. 40 adult male mice were included in this study. To assess the probable health effects of the prepared AgNPs, an experiment has been designed that includes 40 adult mice, and it was randomly divided into three groups as follows: Group I (C): The control group consisting of 10 animals was injected intraperitoneally with PBS for 15 days. Second (G): included 10 animals who were injected with 0.1 mL of (2) mg/kg (G) intraperitoneally for 15 days. Group B included 10 animals injected with 0.1 mL of (2 mg/kg) (B) solution intraperitoneally for 15 days. Changes in some biochemical parameters related to the liver and kidneys were analyzed to assess potential toxic effects on the function of these vital organs. The serum levels of alanine aminotransferase (ALT)(IU/L), alkaline phosphatase (ALP) (IU/L), and cholesterol (mg/dL) as parameters of liver function were analyzed, and the serum levels of uric acid, creatinine, and urea (mg/dL) were analyzed as parameters of kidney function. The results revealed that no significant changes occurred in organ weight in groups treated with AgNPs compared with the control. However, the results showed a significant increase in ALT enzyme level in the third group compared with its level in the control group. Meanwhile, there were no significant differences in ALT level between the second group and the control. The level of the anaplastic lymphoma kinase (ALK) enzyme was significantly increased in both groups (2 and 3) in comparison with its level in the control group. No significant differences were found in cholesterol levels between the groups. Also, there were no significant differences found in uric acid levels between the groups. At the same time, creatinine level increased significantly in group 2 (where the NPs prepared using Black tea as a reducing agent) compared to its level in the control group. Urea level increased significantly in both groups (2 and 3) in comparison with its level in the control group. We conclude that the submission to AgNPs causes toxicity in the liver and kidneys.

Role of Lactobacillus plantarum and Lactobacillus acidophilus as a Treatment of Cryptosporidiosis in Mice
...Show More Authors

Objective: To evaluate the therapeutic activity of probiotics mixture of Lactobacillus plantarum and Lactobacillus acidophilus towards Cryptosporidium infection in experimentally infected mice. Oocysts of Cryptosporidium were separated from the stool of humans to infect mice. Methods: Forty male albino mice were split equally into four groups, every group contained 10 mice, the group I (early treated group), were treated from the 1st day from infection to the 11th post-infection, group II (late treated group), were treated from the 4th day from infection to the 15th post-infection, and group (III) (untreated group), were mice considered as a positive control group. Results: It was showed that daily application of a mixture of L. plantarum w

Estimation of the Cytotoxic Effects of Yucca Gloriosa Variegata Leaves Extract on Albino Mice
...Show More Authors

Yucca gloriosa Variegata L. is a stemless. The whole plant of Y. gloriosa L. has vast medicinal uses. TheNative Americans and North New Mexico used a tea from the leaves and roots to treat asthma, headache,wound healing. As well as it was being consumed as daily dietary. All part of Y. gloriosa L. is rich in saponinsteroidal glycosides. Saponin extracts are well-known to be highly toxic. Hence, present study was carriedout to investigate the toxicity of saponin and estimate the LD50 value which helps in determining the safedose range for the drug that be used, as well as to determine hematological aspects and examine histologicaleffect. Different concentrations of saponin extract were injected into male mice (10,000, 8000, 6000, 400

Capacitance and Resistivity Measurements of Polythiophene /Metallic Nanoparticles-based Humidity Sensors
...Show More Authors

Capacitive–resistive humidity sensors based on polythiophene (P3HT) organic semiconductor as an active material hybrid with three types of metallic nanoparticles (NP) (Ag, Al, and Cu) were synthesized by pulsed laser ablation (PLA). The hybrid P3HT/metallic nanoparticles were deposited on indium-tin-oxide (ITO) substrate at room temperature. The surface morphology of theses samples was studied by using field emission scanning electron micrographs (FE-SEM), which indicated the formation of nanoparticles with grain size of about 50nm. The electrical characteristics of the sensors were examined as a function of the relative humidity levels. The sensors showed an increase in the capacitance with variation in the humidity level.  Whil

The Effect of Ginger Plant (Zingiber officinale) Aqueous Extract on Function and Histological Structure of Kidney in Mice Treated with Carbon Tetrachloride
...Show More Authors

The percent work was designed to determine the effect of ginger plant aqueous extract on function and histological structure of kidney in mice treated with carbon tetrachloride (CCl4). Ginger plant caused a protective effect against CCl4 induced kidney damage and improved the kidney weight and biochemical parameters including urea, uric acid and creatinine. The ginger plant has a protective effect against injury in the kidney of mice treated with CCL4, because the ginger plant protects the tissues of kidney from toxic effect of CCL4. The kidney of CCL4 treated mice showed many histological alterations in the kidney included: atrophy, vascular degeneration and hemorrhage, death cell, degeneration of epithelial cells, destruction of basement
