Parameter of observation were morphology and development of P. berghei at different level of parasitaemia (10%, 20%, 30% and 40%). The result showed from microscopic examination of blood slides prepared from the study animals indicated that the ring form was dominant stage obtained at all different stages of infection followed by trophozoite stage. Meanwhile schizont stage was the lowest stage obtained at all different stages observed
Bioactive Compound and Cytotoxic Analysis of Premna oblongifolia Merr. Ethanol Extract on Rat Bone Marrow-Derived MSC-like Cells
No full textThe use of natural products in regenerative medicine holds significant promise, especially in regions where traditional medicine is prevalent. This study investigates the bioactivity of the ethanol extract of green cincau leaves (Premna oblongifolia Merr.) (GCE) on bone marrow-derived mesenchymal stem cell-like cells (BM-MSCs). The leaves were extracted using the maceration method, and the bioactive compounds were analysed and detected by Gas Chromatography-Mass Spectroscopy (GC-MS). The cytotoxicity tests were conducted across a concentration range of 1–1200 μg/mL using WST-1 reagent, and cell viability was measured at 24, 48, and 72 h. The results of GC-MS indicated 28 bioactive compounds with the dominant groups being terpenoids and fatty acids. The most abundant compounds in GCE were phytol (19.06%), squalene (4.32%), Urs-12-en-28-oic acid, 3-hydroxy-, methyl ester, (3.beta.)- (6.23%) and 8,11,14-Eicosatrienoic acid, (Z,Z,Z)- (2.88%). The GCE maintained cell viability above 80% at all concentrations, indicating low cytotoxicity. Furthermore, Alizarin Red S staining revealed calcium deposit formation at 300 µg/mL, suggesting preliminary osteogenic activity. These findings suggest GCE may have potential for supporting BM-MSCs proliferation and demonstrates early osteogenic properties. Further investigation is recommended to explore its mechanism of action and therapeutic potential in differentiation applications

IMMUNOSTIMULATORY EFFECT OF METHANOL EXTRACT OF FLAMBOYANT LEAF [Delonix regia (Boj. ex Hook.) Raf.] IN MICE
No full textAbstract. Flamboyant [Delonix regia (Boj. ex Hook) Raf.] leaf contains flavonoid compounds that are expected to have immunostimulatory effect. This research was done to determine the effect of flamboyant leaf extract on immune response by accessing the activity of immune cells and capability test the extract as immunostimulant in mice. Leaf extraction was done by maceration using methanol in the Laboratory of Biology of Chemistry Department, Faculty of Mathematics and Natural Sciences of Syiah Kuala University whereas animal treatment and testing were carried out Micro-technique Laboratory of Biology Department of the same faculty. This research used 20 male mice strain Swiss-Webster aged 7-8 weeks were randomly assigned to 4 treatment groups with five replications each. Group 1 (P0) was untreated control; group 1-3 were mice administration flamboyant leaf extract 250 mg/kg BW (P1), 500 mg/kg BW (P2), and 750 mg/kg BW (P3) per oral. The treatments were given for 14 days after one week of adaptation period. Blood samples were collected before and after extract treatment and used for leukocyte count analysis. Phagocytosis activity was accessed by carbon clearance assay on day 15. At the end of the study, all mice were sacrificed for spleen weight analysis. Data obtained was analyzed by Analysis of Variance followed by Tukey test (Leukocyte count and spleen weight) or regression analysis (carbon clearance). The results showed a flamboyant leaf extract administration resulted in increased leukocyte counts that were significantly different (p<0.05) between treatment groups. Phagocytosis test indicated the extract had moderate to strong immunostimulatory effect whereas spleen weight analysis did not show any difference among treatment groups. In conclusion, flamboyant leaf methanol extract was able to increase immune cells and had potential immunostimulatory activity in mice.

The immunostimulant effect of jamblang stem bark (Syzygium cumini L.) ethanol extract against mice macrophages phagocytosis activity and capacity
No full textThis study aims to determine the effect of administering Jamblang Stem Bark Ethanol Extract (Syzygium cumini L.) (JSBEE) on the activity and phagocytosis capacity of macrophages in mice (Mus musculus) infected with Staphylococcus aureus bacteria. The research method used a completely randomized design (CRD) with five treatments and five repetitions, conducted in-vitro and in vivo test. The treatments for in vitro involved administering distilled water (T0), Stimuno (T1), and JSBEE at concentrations of 10 ppm (T2), 100 ppm (T3), and 1000 ppm (T4). Subsequently, in vivo treatment was conducted using distilled water (T0), stimuno (T1), JSBEE at 10 mg/kg (T2), 100 mg/kg (T3), and 1000 mg/kg (T4). Initially, mice underwent in vivo administration of JSBEE, administered orally via catheter tip, with a dosage of 1 mL per 10 g of body weight. JSBEE was administered orally for 10 days, followed by infection with S. aureus on the 11th day. The in vitro tests were conducted by isolating macrophage cells from the intraperitoneal fluid, to which S. aureus and JSBEE were added. Intraperitoneal fluid collected from the mice was used to prepare smears using the thin blood smear method and Giemsa staining. Macrophage phagocytosis activity was observed and assessed based on the percentage activity formula, and the phagocytic capacity of macrophages was measured by the number of S. aureus cells phagocytosed. The results indicated that JSBEE significantly affected (P0.05) both the activity and phagocytic capacity of macrophages in vivo and in-vitro. The best concentration of JSBEE for increasing both the activity value and phagocytic capacity of macrophages was 100 ppm (T3)
