Objective: This study prepared, evaluated immunomodulatory activity of nutraceutical formulation and studied the effect of self-mortification and cow urine distillate fortification methods on the immunomodulatory potential of nutraceutical formulation.Methods: Three types of nutraceutical formulations i.e. Nutraceutical formulation (NF), self fortitfied nutraceutical formulation (SFNF) and self fortitfied nutraceutical formulation fortified with cow urine distillate (SFNECUD) were prepared using fine powders of amla, apple, garlic, onion, wheat grass, papaya, turmeric and cow urine distillate by different methods. The immunomodulatory activity of nutraceutical formulations at a dose of 500 mg/kg was assessed by various immune function parameters like cell-mediated immunity (neutrophil adhesion, delayed type hypersensitivity (DTH) response and cyclophosphamide-induced neutropenia), humoral immunity (serum immunoglobulins level and haemoagglutination antibody titer), and phagocytic activity (carbon clearance and polymorphonuclear (PMN) cell activity).Results: Oral administration of NF, SFNF and SFNFCUD showed significant (p<0.01) increase in adhesion of neutrophils, potentiation of the DTH reaction and attenuation of cyclophosphamide-induced neutropenia. A significant increase in serum immunoglobulin levels and production of circulating antibody titer in response to sheep red blood cells (SRBCs) was also observed. In addition, an increase in the phagocytic index in carbon clearance assay and an increase in the phagocytic activity of PMN cells was observed.Conclusion: From the above results, it can be concluded that all three types of formulations showed significant immunostimulant activity. SFNF and SFNFCUD showed better immunomodulatory activity than NF suggesting the potentiation of immunomodulatory potential of NF activity by fortification methods.

Tinospora cordifolia is a plant well known for its medicinal value in Indian ayurveda and Indian traditional medicine system. However, to prove its efficiency for the clinical utilization, more experimental data will be beneficial. In the present investigation, evaluated the immunomodulatory activity of the alcoholic extracts of Tinospora cordifolia stem on various in-vivo experimental models such as neutrophil adhesion test, phagocytic index by carbon clearance test, Hemagglutinating antibody (HA) titre and delayed type hypersensitivity (DTH) responses. The evaluation of immunomodulatory potential by oral administration of alcoholic stem extracts (50, 100, 200 and 300mg/kg b.w, p.o) evoked a significant increase in percent neutrophil adhesion to nylon fibers as well as a dose dependent increased in antibody titre values, and potentiated delayed type hypersensitivity reaction induced by sheep red blood cells and significant response towards phagocytosis in carbon clearance assay (*p<0.05, *p<0.01, ***p<0.001). This may be due to concentrations of active phytochemicals present in particular plant extract. Hence, it was concluded that the plant extracts increased humoral as well as cell mediated immunity.

     The present study investigated the effect of synthetic non-methylated oligonucleotides containing Cytosine-phosphate-guanosine dinucleotides (Cytosine-phosphate-guanosine oligodeoxynucleotide) on caprine mastitis with Heat Killed Cryptococcus neoformans Ag. 20 healthy local breed does were used with weight ranging of 25-30 Kg and free of mastitis by examination via California Mastitis Test and Somatic Cell Count. The does were allotted into four equal groups, the first group (G1) was treated intramammary with 100μg/kg of Cytosine-phosphate-guanosine oligodeoxy nucleotide on fifth day postpartum in the right mammary gland while the left mammary gland served as control and were infused with sterile phosphate buffered saline. On day 8 postpartum repeat dosages of Cytosine-phosphate-guanosine oligodeoxynucleotide and phosphate buffered saline were infused respectively. On day 9 pp the right mammary gland was infused with 2ml of 2x108 cell/ml of Heat Killed Cryptococcus neoformans Ag. The second group (G2) was infused at day 9 postpartum with 2ml of 2x108 cell/ml of Heat Killed Cryptococcus neoformans Ag in the right mammary gland only. The third group (G3) was left until the challenge test done after one week of immunization in the G1 and G2, by inoculation of 2ml of 5x106 viable C. neoformans in the right mammary gland. The fourth group (G4) was kept as a control receiving 2ml of sterile PBS. Blood samples were collected at 0, 5, 10, 20, 30 and 40 days of the study, to determine the antibody titer by passive haemagglutination assay, while the cell mediated immunity was evaluated by detecting the goat Interferon Gamma by ELISA test and Phagocytic index. Also the cell mediated immunity was determined by delayed type hypersensitivity test after 21 days of immunization. The results showed a significant variation (P≤0.05) between vaccinated groups (G1 and G2) and the control. However, there was a significant increase (P≤0.05) of skin thickness shown after 48 hrs in the G1compared to G2. High level of Interferon Gamma concentration was noticed in the G1 as compared with other groups. Moreover, cell mediated immunity developed effectively in the G1 which was noted by a significant increase (P≤0.05) of phagocytic activity of polymorphonuclear cells. The high level of antibody titer was observed in the G1 as compared with other groups. In conclusion: These results suggest that vaccination with Cytosine-phosphate-guanosine oligodeoxynucleotide plus Heat Killed Cryptococcus neoformans Ag intramammary lead to a good protection of caprine mammary glands against C. neoformans mastitis.

In the present study, an attempt was made to screen immunomodulatory activity of the hydroalcoholic extract (HEDF) of Dendrophthoe falcata (L.f.) Ettingsh (Loranthaceae), an Indian Ayurvedic plant, on different arms of the immune system. HEDF was evaluated for immunological function by studying delayed type hypersensitivity (DTH) to sheep RBCs, nitric oxide (NO) release from murine peritoneal macrophages, phagocytic activity of polymorphonuclear (PMN) cells in vitro and reticuloendothelial system in vivo, plaque forming cell response of splenic lymphocytes to sheep erythrocytes, haemagglutination antibody titer and neutrophil adhesion test. Significant increase in NO production by mouse peritoneal macrophages was detected in culture supernatants indicated increased phagocytic activity of macrophages. After post oral administration of HEDF in three doses of 250, 475 and 950 mg/kg body weight, a significant increase in phagocytic activity of PMN cells/reticuloendothelial system, stimulation of neutrophil function and splenic antibody secreting cells, were also noticed. Stimulation of humoral immune response was further observed with elevation in haemagglutination antibody titer. Heightened DTH reaction suggested convincing evidence for activation of cellular immune system. Present study thus confirms the immunomodulatory activity of the hydroalcoholic extract of D. falcata and the immunomodulatory responses were found to be dose dependent manner.Keywords: Dendrophthoe falcata; Antibody titer; Neutrophil adhesion; Phagocytic activity.© 2011 JSR Publications.

Marchantia Paleacea

Immunostimulants are compounds that can stimulate an immune response by increasing the activity of non-specific and specific components of the immune system (humoral and cellular) against certain infections and diseases. The liverwort plant species Marchantia paleacea Bertol. has long been used as a source of nutrition and empirical medicine. However, scientifically there is still not much research data on immunomodulators in these plants. This study aims to determine the activity of immunomodulators in the ethanol extract of the herb Marchantia paleacea Bertol. in male mice of BALB/c strain. Bioactive compounds from this plant were extracted by maceration method using 96% ethanol. Extract characterization and phytochemical screening were determined according to WHO guidelines and standard procedures from previous studies. The immunomodulatory activity of the extract was tested by carbon clearance method and lymphoid organ index (non-specific responses), primary and secondary antibody titer tests (humoral specific responses), IL-2 cytokine levels and IFN-ɣ from serum secondary antibodies and delayed-type hypersensitivity reaction/DTH (cellular specific response). The results of qualitative phytochemical screening contained flavonoid compounds, saponins, phenolics, tannins and steroids/triterpenoids. The results of the non-specific immune response immunomodulator test showed that the dose of 52 mg/kg bw had the largest phagocytic index of 1.52 which included strong immunostimulation (K > 1.5) and the organ spleen index of 0.55 ± 0.11 which increased significantly compared to the control (p<0.05). The data on the acquisition of specific immune responses in the primary and secondary antibody titer test in the three test extracts resulted in increased titer levels compared to the control and at a dose of 52 mg/kg bw could significantly increase the levels of IL-2 cytokines in the control group (p<0,05). Meanwhile, in the DTH test, doses of 13 and 26 mg/kg bw could significantly increase the thickness of the soles of mice compared to controls (p<0.05).

Background: The immune system is intrinsic to health. Modulation of the immune responses to alleviate the diseases by using herbal plants has been of interest for many years. Diosgenin, a naturally occurring steroid saponin mainly present in the seeds of fenugreek (Trigonella foenum graecum) and in the root tubers of wild yams (Dioscorea villosa). Activation of specific and nonspecific immunity results in stimulation of immune response. Diosgenin has the positive effects on both specific and nonspecific immunity. Aim: To study the immunomodulatory activity of Diosgenin in albino wistar rats. Method: The suspension of Diosgenin was given orally at the dosage level of 50, 100 and 150 mg/kg for 21 days in a rat. The immunomodulatory activity on specific and non-specific immunity was studied by heamagglutination antibody (HA) titer, delayed type hypersensitivity (DTH) response and carbon clearance test.  Immunosuppression in a rat was induced by using Cyclophosphamide (100 mg/kg, p.o.). Sheep red blood cells (SRBCs) were used as antigen (0.1ml 20% SRBCs). Result: Diosgenin exhibited significant increase in the production of antibody titer in response to SRBC antigen. A significant increase in both primary and secondary HA titer was observed in immunosuppressed group treated with Diosgenin when compared with negative control.  A significant increase in the DTH response was observed in immunosuppressed animals treated with Diosgenin, pre-sensitized with SRBCs antigen. Diosgenin exhibited significant increase in phagocytic index against control group, indicating the stimulation of the reticuloendothelial system. Conclusion: The study indicates that Diosgenin triggers stimulatory effect on specific and nonspecific immune response. The immunostimulant effect of Diosgenin could be attributed due to its saponin glycoside.

Delayed-type hypersensitivity (DTH) appears in mice immunized with less than an optimal immunogenic dose of sheep red blood cells (SRBC), but is blocked progressively as antibody production increases in response to larger doses of SRBC. Treatment with cyclophosphamide (CY) was shown to release T cells from this inhibitory influence of the humoral response, and cause enhancement of DTH. The magnitude of this enhancing effect on T-cell activity was markedly dependent on the time of treatment relative to the time of immunization, and on the time chosen for measuring DTH. The reasons for these pronounced effects of timing are threefold: (a) CY given before antigenic stimulation has a long-lasting effect on antibody formation, but no apparent effect on the precursors of activated T cells. (b) After antigenic stimulation, T cells also become susceptible to CY. (c) The production of a nonspecific participant (monocyte) in the DTH reaction is also suppressed by CY, though the supply of circulating monocytes is not immediately affected by the drug. The differential effect of CY on T and B lymphocytes depends on the differing physiological states of the majority of cells that make up these two populations. The former are resting cells that are insensitive to CY until exposed to specific antigen, while the latter are drawn from a rapidly replicating precursor pool and are susceptible to CY at all times.

Immunomodulatory Potential

Artemisia amygdalina D. is a critically endangered endemic medicinal plant of Kashmir Himalayas. In the current study anti-inflammatory and immunomodulatory activity of the plant was carried out. Carrageenan paw edema model was used to study the potential of the drug in inflammation in Wistar rats. SRBC-specific haemagglutination titre and DTH assays were carried out in Balb/C mice for observing the effect of test drugs on immune system. The plant extracts used as test drugs showed to have anti-inflammatory potential. The methanolic fraction was observed to have the maximum effect on the inhibition of paw edema formation with the inhibitory potential of 42.26%, while in the immunomodulation studies the test drugs were found to have the immunosuppressant activity with methanolic fraction again showing the maximum potential for the suppression of both humoral (55.89% and 47.91%) and cell-mediated immunity (62.27% and 57.21%). The plant in total seems to have the anti-inflammatory potential. The suppression of immune system suggests some mechanistic way by which the inhibition of inflammation takes place. Since, in chronic inflammation like arthritis, there is the involvement of immune system, the plant in that way may serve as an alternative for the treatment of such autoimmune diseases.
