Objective: Leishmaniasis is one of the most important parasitic infectious diseases in the world. Since last century, many efforts have been made to control and treat the disease, but appropriate vaccines, pesticides and medicines are not available or even eligible. The purpose of this study was to evaluate the effect of hydro-alcoholic extract of Seidlitzia rosmarinus on the lesions of experim...

Fighting trypanosomiasis with an anti-trypanosome vaccine is ineffective, the parasite being protected by a Variable Surface Glycoprotein (VSG) whose structure modified at each peak of parasitaemia, which allows it to escape host's immune defenses. However, host immunization against essential factor for survival or expression its pathogenicity could achieve same objective. Here we present resul...

Cannabidiol (CBD) is a highly lipidic phytocannabinoid with remarkable anti-inflammatory effects. The aim of this study was to evaluate CBD’s effects and mechanisms action in the treatment mice subjected acute graft-versus-host disease (aGVHD). aGVHD induced by transplantation bone marrow cells splenocytes from C57BL-6j Balb-c mice. recipient were treated daily CBD, reduced mouse mortality decr...

Background: The adjuvanticity potential of Lactobacillus casei was first suggested in an old survey. The present study was designed to investigate the efficacy of a new immunotherapy against breast cancer made by mixing an extract of heated 4T1 mammary carcinoma cell line and a heat-killed preparation of Lactobacillus casei.Methods: Female BALB/c mice (6–8 weeks old, n=40) were challenged subcu...

Transgenic mice that over-express B cell leukemia/lymphomas (Bcl)-2 in myeloid cells under control of the human MRP8 promoter (hMRP8-Bcl-2) or in T lymphocytes under the E micro promoter (E micro -Bcl-2) were compared with C57BL/6 control mice following cecal ligation and puncture (CLP). There was a significant difference in outcome between the hMRP8-Bcl-2 and control mice with 100% survival in...

BACKGROUND We used B16-F10 (B16) melanoma tumor cells and syngeneic C57BL/6 (B6) mice as a study model for pulmonary metastases, to better understand whether or not there exist differences in tumorigenicity and in the effectiveness of immunotherapy as a function of host age (1-, 3-, 12- and 24-month-old). METHODS Intravenous injection of B16 melanoma cells were administered to B6 mice of diff...

Trypanosoma congolense is a protozoan parasite that causes severe diseases in livestock. Three major quantative trait loci (QTL), Tir1, Tir2, and Tir3, control the survival time of mice after infection with T. congolense. Congenic mice carrying the C57BL/6 resistance alleles on the A/J background were developed for each of these loci. The congenic mice were used to physically map the regions co...

Objectives: It was aimed to investigate the effects of different doses of follicle stimulating hormone (FSH) and activin A on the growth and maturation of preantral mouse follicles during the in vitro culture. Methods: Preantral follicles (90-100 µm in diameter) were harvested from 6-8 week-old Syrian mice and cultured in TCM199 culture medium for 6 days to see the effect of FSH and Activin A...

In this study of murine survival, 422 F1 hybrids between DBA/2J (D2) female mice and C57BL/10 (B10) background H-2 congenic male mice (11 strains), 88 F1 hybrids between B10 female mice and B10 background H-2 congenic male mice (3 strains), and 532 control mice from the 11 parental B10 background H-2 congenic mice were bred over a period of 2 yr. Toward the end of the breeding period there was ...
