The Impact of Body Mass Index and Body Composition on Cardiac Autonomic Function in Young Adult Saudi Females

Abstract

The efficacies of four different types of microwaved Toxoplasma gondii vaccines were evaluated for their ability to elicit protection in Swiss strain pregnant mice and their pups. Protection of dams and their pups was evaluated by parasitological and pathological studies. Mice were divided into 4 groups. Preimmunization of pregnant mice was done before mating. The first group immunized with tachyzoite vaccine alone, the second with tachyzoite vaccine in combination with cytokine IL -12 , the third with microwaved cyst vaccine alone and the fourth group with microwaved cyst vaccine combined with cholera toxin. All groups were challenged with the virulent RHstrain of Toxoplasma gondii between the 10 th and 14 th day of gestation. The results showed highest level of protection in dams vaccinated with cyst vaccine in combination with cholera toxin followed by vaccine group in association with the cytokine IL 12 . The combination of the vaccines with the adjuvant strengthened the vaccine effect, thus documented by the improvement of histopathological changes in the organs of both dams and pups compared to the infected control group organs. The study proposes the implication of this vaccine against the infection with Toxoplasma gonidii, not only in mice, but also in other mammalian hosts including women.
