Trypanosomiasis is one of the common parasitic diseases, which infects the dromedary camels and decreases the numbers of these animals in Iraq. To get the best knowledge of the changes of iron status in camels infected with trypanosomiasis, in an attempt to take advantage of these variables as markers for infection, we designed this study. The current study conducted in blood sample collection from155 dromedary camels, 33 were infected (21.29%), according to the status of infection with Trypanosoma evansi that depends on blood smear examination as a golden test. Results denote significant differences of infection ratio by sex and age, from total of 132 male tested, 29 (21.96%) infected, distributed into 12 (%41.37) of age ≤ 2 years and 17 (58.62) of ≥ 2 years. From 23 female tested, 4 (17.39%) were infected at age ≤ 2 years. Furthermore, the results of this study demonstrated significant (p˂0.05) decrease in total serum iron, transferrin saturation, ferritin, whereas increased in total iron binding capacity and unsaturated iron binding capacity in the infected male and female camels with different age. Analyzed data of iron status parameters denoted that the cutoff point test between sensitivity (97) and specificity (100) for serum iron is (≤67.26), for transferrin saturation is (≤17.23) between the sensitivity and specificity (100) and (≥378.66), for total iron binding capacity between the sensitivity and specificity (93.9 and 96.7) respectively. Also, the cutoff point test between the sensitivity (100) and specificity (96.7) for unsaturated iron binding capacity is (≥301.27) and ferritin concentration has a cutoff point is (≤ 249.88) for the sensitivity (100) and specificity (99.2). It could be concluded from what was stated in the results of the current study, that the measurement of the concentration of serum ferritin could be considered as a good marker for the T. evansi infection
There has been a dearth of research on the gastroprotective effect of Conocarpus erectus in the literature so the current study was designed to estimate the ability of Conocarpus erectus (C. erectus) leaves extract alone and in combination with omega-3 regarding gastroprotective effects. A total of 30 male rats were divided into five groups (n = 6). All animals induced gastric ulcer by 80 mg/kg of naproxen orally twice a day for three consecutive days. At the same time, the animals treated orally with 175 mg/kg omega-3, 250 mg/kg C. erectus, 80 mg omega-3 + 150 mg C. erectus, 10 mg/kg of lansoprazole, and 2 ml/kg of DMSO were named T1, T2, T3, T4, and TC, respectively. The obtained results of the present study indicated the presence of flavonoids, saponin, and tannin as active ingredients in C. erectus leaves extract. Consequently, C. erectus seemed to have the potential of chelating metals in a concentration-dependent manner. Gross and histopathology findings showed the highly protective capability of C. erectus and omega-3 against ulcerative lesion, compared to the time each was used alone. The outcomes of the current study indicated that using C. erectus alone or plus omega-3 can protect the gastric mucosa from the ulceration induced by naproxen, and the chelating properties of C. erectus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
