چکیده

Purpose: To study the immunosuppressant and immunopotentiating effects of ketoprofen on antibodyproducing cells. Methods: Mice were given ketoprofen at doses of 1 mg/kg/day and 5 mg/kg/day for seven days. Similarly polyinosinic–polycytidylic acid (Poly IC) and phosphate buffer saline (PBS) were used as positive and negative control, respectively, for seven days. After seven days, the mice were sacrificed and their spleens removed. Simultaneously, blood was withdrawn from the hearts of the mice and serum was separated from the blood. The spleen cells were analyzed by enzyme-linked immunospot (ELISPOT) while the serum was investigated by enzyme-linked immunosorbant (ELISA) to evaluate the effects of ketoprofen on the ability of individual cell to produce antibodies and antibodymediated immune responses. Results: Ketoprofen significantly (p < 0.001) reduced the ability of individual cells to produce antibodies. There was a significant difference (p < 0.001) in % of spot forming cells of PBS treated negative control group (0.045 %) as against positive control (0.058 %), 1 mg ketoprofen /kg/day (0.037 %) and 5 mg ketoprofen/kg/day (0.032 %) treated groups. The results of ELISA showed a significant (p < 0.005) difference in the absorbance values between negative control, positive control, ELISA control and ketoprofen treated groups. Absorbance was significantly (p < 0.005) reduced in ketoprofen-treated groups. Conclusion: The ability of an individual cell to produce antibodies and antibody-mediated immune responses is suppressed by ketoprofen, suggesting that it is immunosuppressive, and thus indicating its potential application in patients with auto-immune disorders.

Effect of Immune Responses Against Hydatid Cyst Antigens on Growth of Melanoma Tumor

Background: Hydatid cyst is the larval stage of the tape worm parasite, Echinococcus granulosus. Human is infected by ingestion of parasite ova excreted in dog feces. The anticancer activity of different antigens of hydatid cyst has been reported in the previous works. In this research, the role of immune system in induction of this anticancer activity has been investigated.Materials and Method...

Effect of Ovarian Induction Using PMSG and HCG hormones on Uterus Dendritic Cells Population in NMRI mice

Introduction: Ovarian hyper-stimulation is widely used in IVF clinics. The main purpose of this method is to stimulate folliculogenesis and increase the number of oocytes in one cycle. Following ovarian hyper-stimulation, hormonal secretion of the ovary, particularly estradiol and progesterone dramatically increases. Immune cells especially dendritic cells have receptors for the estradiol...

EFFECT OF TOXOCARA CANIS SECOND STAGE LARVAE ON THE HOST IMMUNE SYSTEM

We have studied functional alteration of immunocytes in mice following inoculation of Toxocara canis second stage larvae. Results indicated depression of lymphocyte blastogenesis in response to concanavalin-A, phytohemagglutinin and allogeneic non B-cells; however, B-cell polyclonal activation was not affected as indicated by the production of total IgG. In contrast, frequency of antibody ...
