The aim of the paper is to investigate effects of long term x-ray exposure on the human lymphocyte, reactive lymphocyte parameters and morphology of lymphocytes in x-ray technicians at Kirkuk hospitals. The study included 54 apparently healthy male x-ray technicians were matched with another 54 apparently healthy control to show any alteration in the lymphocytes, reactive lymphocytes and morpho...

Introduction . Ablative fractional laser photothermolysis (A-FLPh), used for rejuvenation of aging skin, is based on its controlled damage. Factors the immune system are involved in reparative regeneration processes triggered, which, turn, also subject to age-related remodeling or immunostaining. The aim work was evaluate dynamics response A-FLPh procedure performed correction age-associated fa...

The study included 24 patients, which formed the baseline group — 12 patients with pulmonary tuberculosis in combination COVID-19 infection and control tuberculosis. There were studied leukocyte formula, content of CD3, CD4, CD8 lymphocytes, NO2-+NO3- total its metabolites. obtained results showed that there is a pronounced decrease lymphocytes an unexpressed shift formula to left. lymphocyte d...

Background: Radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (IR). In this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by CHO-K1 cells. Materials and Methods: Whole blood and CHO-K1 cells were cultured in RPMI-1640 complete medium. Cells were separately irradiated with...

Background: Iron deficiency impairs the proliferation and function of T lymphocytes. This study was conducted to assess the relationship between serum iron with percentage of TCD4 and TCD8 lymphocytes in peripheral blood of female high school students in Hamadan.  Methods: In this cross-sectional study, 355 female high school students with an age range of 15-18 years were enrolled from Ja...

stem cells from human exfoliated deciduous teeth (shed) have been introduced recently and  possess characteristics similar to  mesenchymal stem  cells (mscs). because of  their convenient accessibility and safety of harvest, shed can be a preferable source for the ever- increasing mscs’ applications. while they are new, their immunoproperties have not been adequately studied. in this study, we ...

The SARS-CoV-2 virus can enter the cells using S1 viral spike (S) protein, not only by binding to ACE2, but also through other cellular receptors. These candidate receptors include CD46, which, like CD45, belongs pan-leukocyte and is expressed on all types of lymphocytes. In turn, infection accompanied damage almost compartments immune system, mainly T purpose study was evaluate expression leve...

human t-cell lymphotropic virus type 1 (htlv-1) is associated with adult t-cell leukemia/lymphoma (atl) and htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and ham/tsp is the most common clinical manifestation of the virus. ham/tsp is an inflamma...
