Abstract

Abstract. 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 (p0.05) 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.Keywords: Delonix regia, immunostimulant, leukocytes, lymphocyte proliferation.

Abstract

Preservation of ovarian tissue from severely injured or dead valuable animals has the potential to preserve female germ cells of animals. The ability to mature and fertilize of oocytes from preserved ovary of endangered species will allow us to sustain genetic and global biodiversities. The aims of this study were to investigate the viability of oocytes collected from the preserved ovary and its potential utilization for the production of cat embryos followed by in vitro maturation and fertilization. Ovary was preserved immediately in phosphate buffer saline (PBS) at 4 °C for 24 or 48 hours. The quality and viability of oocytes after the maturation process were identified microscopically using aceto-orcein staining. Biological function of the oocytes was evaluated by using in vitro culture technique for the maturation and fertilization rate in CR1aa medium culture. The results showed that the percentage of oocytes collected from preserved ovary for 24 and 48 hours that remained at the stage of metaphase-II were 29.4% and 21.9% respectively. Fertilization rates produced in the IVF using oocytes collected from ovary preserved for 24 or 48 hours were significantly lower (30%) than that of unpreserved control (36.7%). In conclusion, female germ cells of cat ovary preserved at 4 °C in PBS for 2 days were still viable for in vitro fertilization and thus can be utilized for in vitro production of cat embryos. Information obtained can be used as a basis of knowledge of using a combination of physiological reagent and cold-based preservation technique in modern reproductive technology for animals.
