    Objective: Antimalarials are globally used against plasmodium infections, however, information on the safety of new antimalarial combination therapies on the gastric mucosa is scarce. The aim of this study was to investigate the effects of Artesunate-Amodiaquine and Artemether-Lumefantrine on ulcer induction. Malondialdehyde (MDA), reduced glutathione (GSH) and major histological changes in male Wistar rats following ulcer induction using Indomethacin were investigated. Gastric ulcers were in four groups; Group I was administered Artesunate, group II received Artesunate- Amodiaquine, group III received Artemether-Lumefantrine, and group IV was a positive control (normal saline). GroupV was the negative control consisting of healthy rats. Results: Antimalarial combination therapies were associated with a high gastric ulcer index than a single antimalarial agent, Artesunate. In addition, levels of MDA were significantly higher in the combination of therapies while levels of GSH were lower in comparison to Artesunate and the negative control. Microscopically, antimalarial combination therapies were associated with severe inflammation and tissue damage than Artesunate in the gastric mucosa showing that antimalarial combination therapies exert their toxic effects through oxidative stress mechanisms, and this leads to cellular damage. Findings in this study demonstrate a need to revisit information on the pharmacodynamics of major circulating antimalarial agents in developing countries. Keywords: Antimalarials, Pharmacodynamics, Antimalarial Agents, Malaria, Developing Countries, Gastric Ulcers.

    Calcium and s100a1 Protein Balance in the brain– Heart axis in Diabetic Male Wistar Rats.
    (Kabale University, 2021) Keneth Iceland, Kasozi; Nakimbugwe, Dorothy; Ninsiima, Herbert Izo; Kasolo, Josephine; Matama, Kevin; Safiriyu, Abass Alao; Owembabazi, Elna; Ssempijja, Fred; Okpanachi, Alfred Omachonu; Valladares, Miriela Betancourt
    Objectives: Calcium deregulation in diabetes mellitus (DM) is central to the brain–heart axis pathology. This has led to the use of medical plants in complementary medicine such as Amaranthus hypochondriacus (GA). The objective of the study was to establish the effects of grain amaranth feed supplementation on calcium, s100al protein and antioxidant levels on the brain–heart axis in diabetic male Wistar rats. Methods: The study involved six groups (n=5) with DM being induced in 20 rats. To the diabetic rats, Group I received mixtard®, Group II was positive control, Groups III and IV received GA feed supplementation at 25 and 50%. In the nondiabetic rats (n=10), Group V received 50% grain amaranth while Group VI was the negative control. The brain and heart tissues were harvested after five weeks and processed using standard methods. Results: Grain amaranth feed supplementation led to improved calcium levels in DM as compared to the positive control. This also led to increased s100a1, antioxidant levels in the brain–heart axis during DM. This then protected the tissues against oxidative damage, thus preserving tissue function and structure. Conclusions: Grain amaranth’s actions on calcium signaling subsequently affected s100a1 protein levels, leading to improved tissue function in diabetes. Keywords: Calcium, T2DM, Ethnomedicine, Grain Amaranth.
