Background: Diagnostic ultrasound has been used to detect human disease especially fetus abnormalities in recent decades. Although the harmful effects of diagnostic ultrasound on human have not been established so far, several researchers showed it has had bioeffects in cell lines and in experimental animals. Three-dimensional (3D), four-dimensional (4D), and color Doppler sonography are new te...
Background: Progesterone is an endogenous immunomodulator that suppresses T cell activation during pregnancy. The stimulation of membrane progesterone receptors (mPRs) would seem to be the cause of rapid non-genomic responses in human peripheral T cells, such as an elevation of intracellular calcium ([Ca2+] i) and decreased intracellular pH (pHi). Mifepristoneimmune cells compared with progeste...
Effect of ethanolic extract of propolis, royal jelly, honey and bee pollen in comparison with virginiamycin (as growth promoter antibiotic) as regards the performance and immune system of Japanese quail were assessed. We used 256 mixed-sex quail chicks in a completely randomized design by eight treatments, including control, ethanolic extract of propolis 1000 (PE1) and 5000 (PE2) mg kg-1</...
Objective Recurrent vulvovaginal candidiasis (RVVC) is a common cause of morbidity affecting millions of women worldwide. Patients with RVVC are thought to have an underlying immunologic defect. This study has been established to evaluate cell mediated immunity defect in response to candida antigen in RVVC cases. MaterialsAndMethods Our cross sectional study was performed in 3 groups of RVVC pa...
co-infection of tuberculosis and leishmaniasis has been reported previously in patients with altered immune response due to primary or secondary immunodeficiency. these intracellular pathogens have a unique interaction in the host immune response and their development depends on impaired cell-mediated immunity. a case of chronic non-healing cutaneous ulcer with chronic fistulating soft-tissue m...
background: the aim of the present study was the comparison of humoral and cell-mediated immunity in broilers fed with different levels of zinc during a coccidiosis challenge. methods: one hundred and forty- four one-day-old broiler chicks were used with three dietary zinc (40, 120 and 200 mg/kg). at 14 d of age, all birds were inoculated orally with 5×10 3 sporulated oocysts of e. tenella . at...
