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.

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.

Chlorophytum borivilianumSantapau & Fernandes (Liliaceae) is a very popular herb in traditional Indian medicine and constitute a group of herbs used as ‘Rasayan’ or adaptogen. Ethanolic extract of the roots and its sapogenin were evaluated for their immunomodulatory activity. Effect of azathioprine-induced myelosuppresion and administration of extracts on hematological and serological parameters was determined. Administration of extracts greatly improved survival againstCandida albicansinfection. An increase in delayed-type hypersensitivity response (DTH), % neutrophil adhesion andin vivophagocytosis by carbon clearance method was observed after treatment with extracts. Immunostimulant activity of ethanolic extract was more pronounced as compared to sapogenins. The results, thus justifies the traditional use ofC. borivilianumas a rasayana drug.

Previous attempts to establish a relationship between impaired cell-mediated immunity (CMI) and major mood disorders have been limited by a failure to explore the relevance of depressive subcategories or to assess CMI by in vivo methods. In this case-control study CMI was assessed in 57 patients with major depression (31 with melancholic, 26 with non-melancholic disorders), and in age- and sex-matched controls by both in vitro and in vivo immunological techniques. Compared with control subjects and patients with non-melancholic depression, patients with melancholia demonstrated reduced in vivo CMI as assessed by delayed-type hypersensitivity (DTH) skin responses. Although increasing age, severity of depression, hospital admission for treatment, and reported weight loss are correlates of melancholia, none of these factors alone, or in combination, accounted for the differences in DTH responses observed between the two depressive subtypes. These data suggest that impaired CMI in vivo may be limited to those with melancholic disorders. At this stage the factors which account for this effect are unclear.

Purified CD4+ BALB/c spleen T cells obtained 4-6 wk after total lymphoid irradiation (TLI) helped normal syngeneic B cells to produce a vigorous antibody response to TNP keyhole limpet hemocyanin in adoptive cell transfer experiments. However, the same cells failed to transfer delayed-type hypersensitivity to the adoptive hosts as measured by a foot pad swelling assay. In addition, purified CD4+ cells from TLI-treated mice were unable to induce graft vs. host disease in lethally irradiated allogeneic C57BL/Ka recipient mice. In response to mitogen stimulation, unfractionated spleen cells obtained from TLI mice secreted normal levels of IL-4 and IL-5, but markedly reduced levels of IL-2 and INF-gamma. A total of 229 CD4+ clones from spleen cells of both normal and TLI-treated mice were established, and the cytokine secretion pattern from each clone was analyzed. The results demonstrate that the ratio of Th1- and Th2-like clones in the spleens of normal BALB/c mice is 1:0.6, whereas the ratio in TLI mice is approximately 1:7. These results suggest that Th2-like cells recover rapidly (at approximately 4-6 wk) after TLI treatment and account for the early return of antibody helper activity and secretion of IL-4 and IL-5, but Th1-like cells recover more slowly (in approximately 3 mo) after irradiation, and this accounts for the deficit in cell-mediated immunity and the reduced amount of IL-2 and IFN-gamma secretion.

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.
