Introduction: Immunomodulators are molecules of synthetic or biological origin that help to regulate the immune system. Many studies have focuses on exploring for phytochemical compounds that used as immunomodulatory properties in Indonesia, as well as in Sulawesi. The immunomodulatory activity of rhizome extract of E. flexuosa, an endemic flowering plant of Sulawesi on male mice were studied. Methods: 25 male mice (Mus musculus) used were randomly divided into 5 groups and Staphylococcus aureus (ATCC 25923) was used as inducer. The negative control group was given 0.5\% Na-CMC (Carboxymethyl Cellulosa Sodium), positive control group was given stimuno{\textregistered} and treatment groups were an ethanol extract of E. flexuosa with successive doses of 200, 400 and 800 mg/kg body weight (BW) respectively. Each group was given the preparation orally for 7 days and on the 8th day the test animals were induced by Staphylococcus aureus bacteria intraperitoneally. The mice were dissected and the peritoneal fluid was taken to determine the activity of the macrophage cells. Meanwhile, Thomson and Weil method was used to study the acute toxicity test and determine the lethal dose 50 (LD50). Results: The percentage of macrophage activity in each group of negative control, positive control, extract doses of 200, 400 and 800 mg/kg BW respectively were 40.40\%, 82.65\%, 53.05\%, 69.38\% and 82.06\%. Based on the results obtained, it was shown that the E. flexuosa rhizome extract has an optimum dose of 800 mg/kg BW, which was not significantly different from the positive control. Meanwhile, the symptoms of toxicity began to appear from a dose of 600 mg/kg BW to a dose of 2400 mg/kg BW including decreased motor activity, tremor, ataxia, lids and writhing. LD50 expressed in LD50 within the criteria of being practically non-toxic. Conclusions: The E. flexuosa rhizome ethanolic extract showed the immunomodulatory activity at optimum dose of 800 mg/kg BW by the increasing of macrophage phagocytosis activity. Moreover, the extract was also practically non-toxic based on LD50 value.

Introduction: Sungkai (Peronema canescens, Jack.) contains polysaccharides, terpenoids, alkaloids, and polyphenols which have pharmacological activity as immunostimulants. Objective: This study aimed to see how the effect of Sungkai extract as an immunostimulant agent was carried out in vitro and in vivo. Materials and Methods: This study was conducted using two methods, namely in vivo and in vitro. In vivo research method was conducted to test the activity and phagocytic capacity of macrophage cells, the percentage of leukocytes, and the total number of leukocytes. This study used 30 male white mice as the test animals that were randomly divided into 5 treatment groups. Each group was consisting of 6 mice which were given different treatments. The negative control group was given with the 0.5\% NaCMC suspension, the mice test substance group was given with the suspension of Sungkai ethanol extract with various doses of 800, 400, and 200 mg/kgBW, and lastly the comparison group was given with the Stimuno in a dose of 50 mg/kg orally for 7 days. On day 8, blood was taken from the mice{\textquoteright}s vein to count the number and percentage of its leukocytes, then followed by the intraperitoneal injection of a Staphylococcus aureus bacteria suspension. After 1 hour of administration of the bacterial suspension, the peritoneal fluid was taken to be observed for its activity and phagocytic capacity of macrophage cells. The in vitro research method was used to test the viability and immunostimulatory activity of RAW 264.7 cells with the Sungkai extraction at the concentration of 1.10, 100 g/m. This cell viability test using the microtetrazolium (MTT) method aims to see whether the Sungkai sample used is safe and not toxic to RAW 264.7 cells by observing at the cell viability value that should exceed \>90\%. The concentration of Sungkai extraction at 1.10, 100 g/mL was found to be safe and non-toxic to RAW 264.7 cells with a viability value of \>90\%. Thus, this concentration of Sungkai extraction can be performed for its immunostimulatory activity test on LPS induced of RAW 264.7 cells by observing their levels of IL-6 and TNF-α. (proinflammatory cytokines) were compared with the LPS alone as a control using the sandwich ELISA (Enzyme-Linked Immunosorbent Assay) method. Results: The observations were analyzed by one-way ANOVA and Duncan{\textquoteright}s follow-up test (significance was taken at p\<0.05). The results showed that variations in concentration increased significantly (p\<0.05) on the activity and phagocytic capacity of macrophage cells, along with the total leukocyte cells. The percentage of leukocytes showed that the cells had a significant increase (p\<0.05). It was found that the Sungkai extraction on 1.10, 100 g/mL could significantly increase the concentration of TNF- and IL-6 (p\<0.05) which were tested by one-way ANOVA and followed by Duncan{\textquoteright}s post hoc test. Conclusion: Sungkai leaf extract (Peronemacanescsens Jack.) in a dose of800, 400, and 200 mg/kgBW has an immunostimulant effect both in vivo and in vitro.

Coriander has long been used by humans as a traditional drug and to enhances the taste of foods. This study aims to know the effects of coriander ethanol extract against phagocytosis activity and capacity of the macrophage cells and the percentage of leukocytes. The test animals used were white male mice which divided into 4 groups and each group consists of 5 mice. The first group (control) was given with 0.5\% Na CMC suspension. The second, the third, and the fourth groups were given with coriander extract each with doses of 100 mg/kg, 140 mg/kg and 200 mg/kg orally for 7 days long. On the 8th day, the mice were induced by Staphylococcus aureus to help their immune system. The results showed that the administration of coriander extract at doses of 100, 140 and 200 mg/kg can increase the phagocytic activity of macrophages by 44.6\%; 54.2\%; and 60.2\% each, while the phagocytic capacity replaces the results of 95.8; 104.4; and 126 cells. The total number of leukocytes showed were 5210, 6190, and 7310 /μL blood. In the number of leukocyte cells, the amount of coriander extract can reduce the number of neutrophil and monocyte cell segments. The conclusion of this study regarding coriander ethanol extract at doses of 100, 140 and 200 mg/kg can increase phagocytosis activity and capacity of the macrophage cells and the total leukocyte cell counts in male white mice.

Background: The lack of vaccines and limitations of currently available strategies demand a need to develop safe and efficacious immunomodulators. Phyllostachys bambusoides is traditionally used for various autoimmune and infectious disorders, a property possibly attributable to presence of flavonoids like orientin and iso-orientin. Objective: the objective of this study was, to search a potent immunomodulator which elicit both Th1 and Th2 immune response. Methods: The animals were (Balb/c) treated with the bioactive fraction (PBC) from P. bambusoides (100 and 200 mg/kg body weight) for 14 days with SRBC (Sheep Red Blood Cells) as an antigen. Haemagglutination antibody (HA) titre, delayed type hypersensitivity (DTH) reaction, phagocytic index, NO production, analysis of cytokines in serum and CD80/ CD86 population in spleen. Results: PBC significantly enhanced the expression of IgM and IgG titre and DTH response in a dose dependant manner after 24 and 48 h in BALB/c mice with a maximum response at 200 mg/Kg. Besides humoral and cell mediated immunity, it also enhanced phagocytic index, nitric oxide production, which further leads to protection against Candida albicans infection. It also, enhanced the expression of CD80 and CD86 in splenic cells. Conclusion: Taken together these in vitro and in vivo data, our results suggest that PBC acts as an effective immunostimulator which specially enhances macrophage function during infection. This further supports the role of PBC in immunopharmacologic applications.
