Abstract

Tinospora cordifolia (Tc) is an Indian medicinal plant with proven immunomodulatory activity. This study was performed to elucidate its possible mechanism of action. We measured CFU-GM Cotony forming units of the granulocyte-macrophage series in serum of mice treated with Tc. We found that 10 days treatment with Tc (100 mg/ kg/d) induced a significant (p < 0.01) increase in the number of CFU-GM (255 +/- 49.32 vs 38.51 +/- 9.98) This suggests that activation of macrophages by Tc leads to increase in GM-CSF which leads to leucocytosis and improved neutrophil function.

  ::   IntroductionTop


Tinospora cordifolia (Tc) is an Indian medicinal plant with powerful immunostimulant effects[1]. It has been reported to increase leucocyte counts and ablate neutropenia following single and multiple doses of cyclophosphamide[2],[3]. Pre-treatment with Tc has also been shown to afford protection against induced infections in Mice[4] and rats[5].

This study was performed to elucidate the possible mechanism of action of Tc. In view of the fact that Tc induced leucocytosis, we measured CFU-GM (colony forming units of the granulocyte  macrophage series) activity in serum of mice treated with Tc.

Swiss albino mice of either sex, weighing between 1822g were used for the study. 20 mice were treated with an aqueous extract of Tc in the dose of 100 mg/ kg orally for 10 days. Another set of 20 mice acted as a control group and were given 1 ml/day distilled water for 10 days.

On the 11th day the mice were sacrificed and blood was collected from the heart. Total and differential white blood cell counts were performed. Serum was separated and frozen at 80?C. This was used as the source for colony stimulating activity.

Agar Colony Assays For CFU - GM: Ability to induce colony forming units of granulocyte  macrophage series by serum from Tc treated mice was compared to that induced by serum from control mice. The agar colony assay was done by using the method given by Burgess, et al[6]. One millilitre of under layer containing 9 parts of Duibecco's Modified Essential Medium (DMEM) plus 20% new born Calf Serum (NBCS) and 1 part 3% agar was allowed to gel in 35 mm plastic petridishes. One millilitre of the overlay containing 9 parts DMEM plus 20% NBCS containing 1 part 2 % agar was added to the gelled under layer. In the test plates 10 ul serum from Tc treated mice was added while in the control plates 10 ul of serum from distilled water treated mice was added.

Mononuclear cells from normal bone marrow were seeded at 2 X 105/ml in the nutritive agar overlay. Colonies were observed after 14 days with 2.5 X objective and 10 X eye piece. Four replicates were made with each source of CSA. The culture dishes were incubated at 37?C in 7.5% CO2 in air in a fully humidified atmosphere. Colonies (> 20 cells) were counted on day 14.


  ::   ResultsTop


As expected, treatment with Tinospora cordifolia for 15 days induced leucocytosis with predominant neutrophilia. Thus, on Day 10 the total white cell count in the control mice was 7800 + 1028 (Mean + SE) while that in the Tc treated group was 14237 1236, representing a statistically significant (p < 0.001) increase of 82%. Similarly, the absolute neutrophil count in the Tc treated group was 9078 +260, which was significantly (p < 0.001) more than in the control group (3900+266).

The number of colonies (> 20 cells) in each plate of the test and control plates is given in [Table:1].


  ::   DiscussionTop


These results indicate that treatment with an aqueous extract of Tc for 10 days at a dose of 100 mg/kg orally leads to significant increase in CFU - GM activity in the serum. Tc has been earlier shown to stimulate macrophages[5]. It is known that activated macrophages secrete GMCSF This haematopoietic growth factor leads to an array of effects including induction of leucocytosis as well as prevention of cytotoxic chemotherapy induced neutropenia[7]. The entire spectrum of activity shown by Tc can be explained by this effect of inducing secretion of GM-CSF.

The results of this study further confirm that Tinospora cordifolia has a great potential as an immunomodulator and may be useful in clinical conditions where GMCSF has been evaluated.
