The stimulatory effect of Andrographis paniculata extract and andrographolide on cytotoxic T lymphocyte (CTL) production was determined in BALB/c mice by Winn's neutralization assay using CTL sensitive EL4 thymoma cells as target cell. Extract and andrographolide showed a significant increase in CTL production in both the in vivo and in vitro models. The(More)
Inhibition of angiogenesis is currently perceived as one of the promising strategies in the treatment of cancer. In this study we analyzed the antiangiogenic activity of Andrographis paniculata extract (APE) and its major component andrographolide (ANDLE) using both in vitro and in vivo models. Intraperitoneal administration of APE and ANDLE significantly(More)
In this study, we explored the antioxidant and anti-inflammatory properties of the medicinal herb Andrographis paniculata using in vitro as well as in vivo systems. Methanolic extract of Andrographis paniculata was found to inhibit formation of oxygen derived free radicals such as superoxide (32%) hydroxyl radicals (80%) lipid peroxidation (80%) and nitric(More)
Cancer is a disorder characterized by uncontrolled proliferation and reduced apoptosis. Inducing apoptosis is an efficient method of treating cancers. In this study, we investigated the effect of andrographolide on the induction of apoptosis as well as its regulatory effect on the activation of transcription factors in B16F-10 melanoma cells. Treatment of(More)
Effects of Andrographis paniculata extract and its major component, andrographolide, on cell-mediated immune responses in metastatic tumor bearing animals were studied. NK cell mediated target cell lysis was enhanced by the administration of Andrographis paniculata extract (45.0% cell lysis) and andrographolide (40.2% cell lysis) on the 5th day after tumor(More)
Major drawbacks of chemotherapeutic agents are their toxic side effects and lack of tumor specificity. Immunological and biochemical studies were here carried out to investigate protective effects of ethanolic extract of Andrographis paniculata against cyclophosphamide (CTX) induced toxicity in vivo. Intraperitoneal administration of the extract(More)
Modulation of immune responses is highly relevant in tumor cell destruction. The present study is focused on the effect of Andrographis paniculata extract (APE) and its isolated compound andrographolide (ANDLE) on cell-mediated immune responses in normal and tumor-bearing control animals. Treatment with APE and ANDLE significantly enhanced natural killer(More)
An important problem in channel equalization, is that of, removing distortions introduced by linear or nonlinear message corrupting mechanisms in the reconstruction of the original signals. Severe nonlinear distortions can make it difficult for conventional equalizers to reconstruct the original signals. In this paper, we propose a Decision Feedback(More)
The protective effect of Andrograhis paniculata and andrographolide (ANDLE) against cyclophosphamide (CTX)-induced urothelial toxicity was investigated in this study. Pretreatment of Swiss albino mice with A paniculata extract (10 mg/dose/animal intraperitoneally [ip]) and ANDLE (500 microg/dose/animal ip) could significantly reduce CTX (1.5 nmol/kg body(More)
Modulation of immune responses to alleviate disease has been of interest for a long time. Intraperitoneal administration of Andrographis paniculata extract along with whole body hyperthermia (WBH) was found to enhance the total WBC count in cyclophosphamide (CTX) and radiation treated animals when compared to untreated control animals. Maximum inhibition in(More)
