Andrographia paniculata a Miracle Herbs for cancer treatment: In vivo and in vitro studies against Aflatoxin B1 Toxicity

The history of natural products used in ancient times and in folk medicine these days, around the world, is the basis for the use of many therapeutic drugs in modern day medicine. Andrographia paniculata belongs to the family Acanthaceae or Kalmegh and is commonly known as 'king of bitters'. It is extensively used as home remedy for various diseases in Indian traditional system as well as in tribal system in India for multiple clinical applications. In our present work, extracts of these ayurvedic plants were tested for their anticlastogenic, and anticarcinogenic properties against Aflatoxin Bl induced toxicity. We used the in vitro method i.e. human lymphocytes culture and in vivo method in bone marrow cells of albino mice, while the parameters studied included chromosomal aberrations [CA], sister chromatid exchanges [SCEs] and cell growth kinetics [RI] both in the presence as well as in the absence of exogenous metabolic activation system for in vitro studies, whereas total aberrant cells and the frequencies of aberrations were used for in vivo methods A. paniculata extracts significantly reduced chromosomal aberrations from 35.0%, 62.0% and 69.0% level [at 24, 48, and 72 h due to Aflatoxin B1] to 21.72%, 44.0% and 52.0%, similarly sister chromatid exchanges were reduced from 14.60 per cell to 7.50 per cell at 48 h of treatments and replication index was enhanced in vitro for each concentration and duration of treatment. In conclusion A. paniculata extracts significantly reduced the number of aberrant cells and frequencies of aberration per cell at each concentration and duration of exposure in vivo; similarly it reduced chromosomal aberrations and sister chromatid exchanges and replication index was enhanced in vitro that was statistically significant at < 0.05 level

Terminalia arjuna, a herbal remedy against environmental carcinogenicity: An in vitro and in vivo study

Medicinal plants have been a major source of therapeutic agents from ancient times to cure diseases. The evaluation of rich heritage of traditional medicine is essential. The bark of Terminalia arjuna is rich in polyphenols [60-70%] including flavonoids and tannins. The aim of the present investigation is to highlight the anticarcinogenic and antimutagenic potential of extracts of T. arjuna. In this experiment we have used human lymphocyte culture and bone marrow cells of albino mice as assay system. The parameters studied included chromosomal aberrations [CA], sister chromatid exchanges [SCEs] and cell growth kinetics [RI] both in the presence and in the absence of exogenous metabolic activation system for in vitro experiment, whereas total aberrant cells and the total frequencies of aberrations were taken for in vivo study. The role of T. arjuna extracts in reducing metaphase aberrations due to aflatoxin B[is quite significant, the reduction varying from 23.49%, 42.47%, and 59.65% down to 12.32%, 28.00%, and 36.88% respectively at the highest dose [TA[4]] for the three different durations viz., 24, 48 and 72 h. Similarly the number of sister chromatid exchanges got reduced from a higher level of 15.00 +/- 1.40 per cell to 7.70 +/- 0.50 per cell with S9 mix at 48 h of treatment. The replication index was enhanced from 1.33 to 1.55 in vitro. Similar trends were noticed in the in vivo experiments i.e., effective reductions in clastogeny ranging from 15.22% to 54.82% from the mutagen treated positive control and the total frequencies in aberrant cells got reduced from 429 due to AFB1 to 141 due to 5th concentration of Terminalia extracts at 32 h of exposure. The ameliorating potential of Terminalia extracts was dose and time dependant

Antigenotoxic and anticlastogenic potential of Agaricus bisporus against MMS induced toxicity in human lymphocyte cultures and in bone marrow cells of mice

The aim of the present study is to evaluate, for the first time, antigenotoxic potential of Agaricus bisporus against methyl methanesulphonate induced toxicity in human lymphocyte culture in vitro and in bone marrow cells of albino mice in vivo. The parameters studied included total aberrant cells and the frequencies of aberrations in the bone marrow cells at three exposure durations viz., 16, 24 and 32 h, and for the in vitro method using chromosomal aberrations, sister chromatid exchanges and replication indices as markers. The alcoholic extract of A. bisporus was taken in five increasing concentrations of 200, 250, 300, 350 and 400 mg/kg body weight for three in vivo exposure durations viz., 16, 24 and 32 h. Similarly, four doses of extracts viz., 150, 200, 250 and 300 ?g/ml of culture were taken for in vitro durations of 24, 48 and 72 h in the presence as well as the absence of S9-mix. The treatment reduced the total number of aberrant cells ranging from 10.0% to 46.15% and it reduced the total frequencies of aberrations ranging from 198 to 96 against very high aberrations i.e., 227 caused due to methyl methanesulphonate in vivo. The same trends were observed in the in vitro experiments i.e., it reduced chromosomal aberrations from [42.00%, 71.25%, and 83.00% to 20.00%, 39.50%, and 43.00%] at 24, 48, and 72 h of exposure respectively. However when experiments were carried out in the presence of liver S9 fraction, these values were respectively 52.38, 44.56, and 48.34% significant at <0.05 level, likewise it also reduced sister chromatid exchanges from 14.86 +/- 1.44 down to 8.84 +/- 0.75 per cell, whereas the replication index got enhanced from 1.45 to 1.64

Does caesalpinia bonducella ameliorate genotoxicity? An in vitro study in human lymphocyte culture and in vivo study in albino mice

Most of the world's populations residing in developing countries depend on alternative medicine and use of plant ingredients. The plant Caesalpinia bonducella belongs to the family of Caesalpiniaceae and it is commonly known as Natakaranja in Hindi. It contains bonducin and two phytosterols namely sitosterol and hepatsane. The twigs and young leaves of C. bonducella are rationally used for curing tumors, inflammation and liver disorders. In our present work alcoholic extracts of this ayurvedic plant were tested for their antimutagenic and anticarcinogenic properties. The aim of the study is to investigate the antimutagenic and antigenotoxic potential of alcoholic extracts of C. bonducella against methyl methane sulfonate [MMS] induced genotoxicity. In this experiment we have used in vitro method i.e., human lymphocyte culture and in vivo method in bone marrow cells of albino mice, while the parameters studied included chromosomal aberrations [CA], sister chromatid exchanges [SCEs] and cell growth kinetics [RI] both in the presence as well as in the absence of exogenous metabolic activation system for in vitro studies whereas total aberrant cells and the frequencies of aberrations were used for in vivo methods. Alcoholic extracts of C. bonducella significantly reduce chromosomal aberration from 42.75%, 44.25%, and 51.75% levels [at 24, 48, and 72 h due to methyl methane sulfonate [MMS]] to 28.50%, 30.25%, and 35.10%, respectively similarly sister chromatid exchanges were reduced from 7.70 +/- 1.50 to 5.20 +/- 1.50 at 48 h of treatment and replication index was enhanced in vitro for each concentration and duration of treatment and their ameliorating potential was dose and duration dependent. Similarly these extracts significantly reduced the number of aberrant cells and frequency of aberrations per cell in in vivo
