Objective: To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl4 intoxicated Swiss albino mice. Methods: First group of mice (n=5) received CCl4 treatment at a dose of 0.5 mL/kg bw (i.p.) for 7 days. Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for 15 days. The third group was given both the turmeric extract (for 15 days, orally) and CCl4 (for last 7 days, i.p.). The fourth group was kept as a control. To study the liver function, the transaminase enzymes (SGOT and SGPT) and bilirubin level were measured in the serum of respective groups. For assaying the immunotherapeutic action of Curcuma longa (C. longa), non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups. Results: The result of present study suggested that CCl4 administration increased the level of SGOT and SGPT and bilirubin level in serum. However, the aqueous extract of turmeric reduced the level of SGOT, SGPT and bilirubin in CCl4 intoxicated mice. Apart from damaging the liver system, CCl4 also reduced non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages. Administration of aqueous extract of C. longa offered significant protection from these damaging actions of CCl4 on the non specific host response in the peritoneal macrophages of CCl4 intoxicated mice. Conclusions: In conclusion, the present study suggests that C. longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.

Objective: To investigate the antibacterial effect of Curcuma longa (C. longa), Zingiber officinale (Z. officinale) and Tinospora cordifolia (T. cordifolia) against Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Bacillus subtilis and Proteus mirabilis of clinical origin. Methods: The antimicrobial efficacy of said medicinal plants and establishment of multidrug resistant character of these bacteria were carried out using disc diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) methods. Results: The results of MIC and MBC showed that these clinical bacterial isolates were phenotypically multidrug resistant against standard antibiotics (>500 μg/mL). Compared to standard antibiotics, C. longa, Z. officinale and T. cordifolia were more effective in killing these microbes as evident from MIC and MBC values (5 to 125 μg/mL). Moreover, C. longa had highest antibacterial efficacy compared to Z. officinale and T. cordifolia. Conclusions: The result thus obtained suggests that bioactive principles of these plants can be used particularly against these multidrug resistant bacteria of clinical origin.
