Background: - Aspergillus fumigatus is a ubiquitous and opportunistic fungal pathogen causing sever invasive aspergillosis, an important source of morbidity and mortality in
immunocompromised hosts (human and animals) .The present study was conducted to obtain more clarification about the toxicity and histopathological effects of this pathogen in albino mice
Material and Methods :- fourteen male mice( 6-10) weeks old ,( 20 – 28) gm weight , divided into two groups , test group ( n= 8) , intranasally infected with 25μl (710 conidia / ml normal
saline ) of A. fumigatus for 7 successive days , compared with uninfected group ( n=6) . the weight of all animals were measured at the beginning and at the end of th

The results of the phytochemical analysis of the crude aqueous and
methanolicextracts of Myrtle (Myrtuscommunis), peppermint (Menthapiperita) and
Sweet basil(Ocimumbasilicum) contain active compounds : Phenols, Flavonoids and
Tannins and missing of Steroids and Coumarines in all extract but Saponins and
Alkaloids found in methanolicextract only, while terpens were present in peppermint
and basiland absent in Myrtle. Administratingto animals with different extracts
showed no effect on serum Acetylcholinesterase (AchE) compared withthese fed on
ethanol liquid diet, Methanolicand aqueous extracts of Myrtle, peppermint and

Background: Wound healing is a complicated, interactive, integrative process involving cellular and chemotactic activity, the release of chemical mediators and associated vascular response which includes number of phases: inflammatory phase, proliferative phase and remodeling phase. Low level laser therapy can be more effective in the three overlapping phases of wound healing. Biostimulation appears to have an effect on the cellular level, by increasing cellular function and stimulating various cells. The aim of present study was to evaluate histologically the effect of 780-805 diode laser the intensity of inflammation and pattern of epithelization in mice model. Material and methods: The experimental study was performed on ninety six white

Acute toxicity is a step to evaluate the toxicity of a substance. Rutin is one of the flavonoid compounds with a variety of pharmacological effects. The aim of the study is to calculate the lethal dose that affect fifty percent of the mice used in the experiment (LD50). Thirty Swiss albino male and 30 non-pregnant female mice have been divided equally and randomly into 5 treated groups and one control group (n=5)  Rutin has been administered with  concentrations 5, 2.5.1.25,0.625 and 0.312 g/kg administered as a single dose intraperitoneally (IP) while the control group received 1% DMSO (IP).  Animals were observed for any morbidity and mortality for 14 days. After 14 days the animal blood collected for biochemical and hem

Background:Ovulation constitutes a central event in ovarian physiology, and ovulatory dysfunction which is a relevant cause of female infertility. Mammalian ovulation is comparable to aninflammatory reaction since many of the molecules responsible for inducing the inflammatorycascade including PGs, leukotrienes and various cytokines have been describedin the ovary.
Objectives:This study was designed to compare between the effects of some NSAIDs(aspirin,diclofenac sodium and meloxicam)on the ovulatory process and the reproductive tract of female mice.
Materials and methods:Twenty four female mice were subdivided into 4groups (6 animals/group).The first received distilled water serve as control group, the second receivedaspirin (7.5

Background: Promotion of bone health is particularly important for young women at reproductive age group, as the critical years for building bone mass are from pre-adolescence to about age 30 years.
patients and Methods: This cross sectional study was performed on three groups, first group of 30 women who had used combined pills for more than 2 years, second group of 30 women who had used Depo-Provera for more than 2 years, last group contain 30 women who had used barrier method or they didn’t use any contraceptive as a control group.Bone mineral density (BMD) of lumbar spine (L2-L4), right proximal femur was determined by dual energy x-ray absorptiometry in (femoral neck, greater trochanter, ward’s t

    In this research, the rabbits' bones have been fractured, the rabbits were exposed to the cold plasma for five minute times two weeks. The microwave plasma voltage which was used in the search was "175v" and the gas flow was" 2 L" at the room temperature.  A Biologic parameters such as alkaline phosphates (ALP), osteocalcin, vitamin D (Vit. D) and calcium (Ca), Triglycerides (TG), Cholesterol (T.chol.), Estradiol and Glucose have studied in its serum. Physiological parameters were measured to prove the effects of plasma on the fracture bone tissue and show the amount of damage and the effect of plasma therapy before and after exposure to plasma.

Three different distribution modules of silicon solar cells in a panel are used in this study . Each module consists of five identical circular silicon solar cells of radius (5cm) and then the total panel areas are identical. The five solar cells are arranged in the panel in different shapes: circular, triangular and rectangular .The efficiency for these three panel distribution are measured indoor and outdoor. The results show that the efficiency is a function of the cells distribution.

Background: Adipose derived-mesenchymal stem cells have been used as an alternative to bone marrow cells in this study. Objective: We investigated the in vitro isolation, identification, and differentiation of stem cells into neuron cells, in order to produce neuron cells via cell culture, which would be useful in nerve injury treatment. Method: Mouse adipose mesenchymal stem cells were dissected from the abdominal subcutaneous region. Neural differentiation was induced using β-mercaptoethanol. This study included two different neural stage markers, i.e. nestin and neurofilament light-chain, to detect immature and mature neurons, respectively. Results: The immunocytochemistry results showed that the use of β-mercaptoethanol resulted in

stem cells are cells found in most of not all, multicellular organisns. these cells are characterized by the ability to self-renew through mitotic divisions and to differentiate into diverse range of specialized cell types to form a whole organism.
