The chemical structure of the main fluorescenting compound in the ethanolic extract (mother tincture) of the American yellow jasmine, Gelsemium sempervirens, was determined by employing 1H nuclear magnetic resonance (NMR), 13C NMR, mass spectroscopy, high-performance liquid chromatography (HPLC), correlation spectroscopy (COSY), and Fourier transform infrared (FTIR) spectroscopy analyses. Spectrofluorometric analysis has been made of the mother tincture and its agitated serial dilutions (up to 12th potency) prepared according to a homeopathic procedure in which serial, agitated dilutions were made separately in glass and polypropylene containers. The succussions were made by employing three different modes: hand jerk, sonication, and vortexing. The chemical formula of scopoletin, the main fluorescent compound, was determined to be C10H8O4 having a molecular weight of 192.17. Significant differences were noted between the remedies prepared in the two types of containers. Further, a comparison between any two methods of agitation revealed significant differences in fluorometric data of remedies at certain potency levels. The biological (anticancer) action of the crude extract, the alkaloid scopoletin, and 2C potency of Gelsemium sp were tested in vitro on the HeLa cell line through fluorescence microscopy, the 3(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, and fluorescent activated cell sorting (FACS). The role of nanoparticles presumably derived from the containers, their orientation, and their interaction with the starting substance during the dynamization process initiated by different modes of agitation could possibly be attributed to the differences noted in the fluorometric data of potencies prepared in the two types of containers and among the three different means of succussion tested.

In homeopathy, ability of ultra-high diluted drugs at or above potency 12C (diluted beyond Avogadros limit) in ameliorating/curing various diseases is often questioned, particularly because the mechanism of action is not precisely known. We tested the hypothesis if suitable modulations of signal proteins could be one of the possible pathways of action of a highly diluted homeopathic drug, Secale cornutum 30C (diluted 1060 times; Sec cor 30). It could successfully combat DMBA + croton oil-induced skin papilloma in mice as evidenced by histological, cytogenetical, immunofluorescence, ELISA and immunoblot findings. Critical analysis of several signal proteins like AhR, PCNA, Akt, Bcl-2, Bcl-xL, NF-κB and IL-6 and of pro-apoptotic proteins like cytochrome c, Bax, Bad, Apaf, caspase-3 and -9 revealed that Sec cor 30 suitably modulated their expression levels along with amelioration of skin papilloma. FACS data also suggested an increase of cell population at S and G2 phases and decrease in sub-G1 and G1 phages in carcinogen-treated drug-unfed mice, but these were found to be near normal in the Sec cor 30-fed mice. There was reduction in genotoxic and DNA damages in bone marrow cells of Sec Cor 30-fed mice, as revealed from cytogenetic and Comet assays. Changes in histological features of skin papilloma were noted. Immunofluorescence studies of AhR and PCNA also suggested reduced expression of these proteins in Sec cor 30-fed mice, thereby showing its anti-cancer potentials against skin papilloma. Furthermore, this study also supports the hypothesis that potentized homeopathic drugs act at gene regulatory level.

Repeated injections of arsenic trioxide induced oxidative stress and hepatotoxicity in mice as revealed from elevated levels of glutamate oxaloacetate transaminases, glutamate pyruvate transaminases, acid and alkaline phosphatases, lipid peroxidation along with reduction of superoxide dismutase, catalase, reduced glutathione content, glutathione reductase and succinate dehydrogenase activities. The present investigation was undertaken to test whether simultaneous feeding of vitamin C can combat hepatotoxicity in arsenic intoxicated mice. Hepatoprotective potential of vitamin C was indicated by its ability to restore GSH, SOD, CAT, AcP, AlkP and GRD levels towards near normal. Electron microscopic studies further supported the biochemical findings confirming the hepatoprotective potential of ascorbic acid. Besides, cytogenetical endpoints (chromosome aberrations, micronuclei, mitotic index and sperm head anomaly) were also analyzed. Administration of vitamin C alone did not show any sign of toxicity of its own. Based on the present findings, ascorbic acid appears to have protective effects against arsenic toxicity and oxidative stress.

To examine whether elevated antinuclear antibody (ANA) titers reported in random human population of arsenic contaminated villages can be reverted to the normal range by administration of a potentized homeopathic drug, Arsenicum album, randomly selected volunteers in two arsenic contaminated villages and one arsenic-free village in West Bengal (India) were periodically tested for their ANA titer as well as various blood parameters in two types of experiments: ‘placebo-controlled double blind’ experiment for shorter duration and ‘uncontrolled verum fed experiment’ for longer duration. Positive modulation of ANA titer was observed along with changes in certain relevant hematological parameters, namely total count of red blood cells and white blood cells, packed cell volume, hemoglobin content, erythrocyte sedimentation rate and blood sugar level, mostly within 2 months of drug administration. Thus, Arsenicum album appears to have great potential for ameliorating arsenic induced elevated ANA titer and other hematological toxicities.

INTRODUCTION Homeopathy is a popular form of complementary and alternative medicine and is used to treat for certain liver ailments. AIM To analyze the efficacy of homeopathic Chelidonium majus (Chel) 30C and 200C in amelioration of experimentally induced hepato-toxicity in rats. METHODS Rats were randomized into six sub-groups: negative control; negative control+EtOH; positive control; positive control+EtOH group; Chel 30; Chel 200. Rats were sacrificed at day 30, 60, 90 and 120; various toxicity biomarkers and pathological parameters were evaluated. Gelatin zymography for determination of metalloproteinases activity and Western blot of p53 and Bcl-2 proteins were also employed. All analyses were observer blind. RESULTS Chronic feeding of p-dimethyl amino azo benzene (p-DAB) and phenobarbital (PB) elevated the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), triglyceride, cholesterol, creatinine and bilirubin and lowered the levels of glutathione (GSH), glucose-6-phosphate dehydrogenase (G-6-PD), catalase and HDL-cholesterol. There were statistically significant modulations of these parameters in the treated animals, compared to positive controls. In both treated groups, there was downregulation of metalloproteinases, p53 and Bcl-2 proteins compared to over-expression in the positive control groups. CONCLUSION Both the potencies of Chel exhibited anti-tumor and anti-oxidative stress potential against artificially induced hepatic tumors and hepato-toxicity in rats. More studies are warranted.

Objectives: To evaluate the efficacy of 2 potentized homeopathic remedies of Arsenicum Album (Ars Alb) – 6C and 30C – in combating chronic arsenic toxicity induced by repeated sublethal injections in mice (Mus musculus). Methods: Mice were randomized and divided into sets: (1) normal (control 1); (2) normal + succussed alcohol (control 2); (3) As2O3 (0.016%) injected at 1 ml/100 g body weight every 7 days (treated); (4) As2O3 injected + succussed alcohol (positive control); (5) As2O3 injected + Ars Alb 6C (drug-fed); (6) As2O3 injected + Ars Alb 30C (drug-fed). Cytogenetical endpoints like chromosome aberrations, micronuclei, mitotic index, sperm head abnormality and biochemical protocols like acid and alkaline phosphatases, aspartate and alanine aminotransferases, reduced glutathione, lipid peroxidation, catalase and succinate dehydrogenase were studied at 30, 60, 90 and 120 days. Results: Compared to controls, chromosome aberrations, micronuclei, sperm head abnormality frequencies and activities of acid and alkaline phosphatases, aspartate and alanine aminotransferases and lipid peroxidation were reduced in both drug-fed series, while mitotic index and activities of glutathione, catalase and succinate dehydrogenase were increased. Ars Alb 30C showed marginally better efficacy than Ars Alb 6C. Conclusion: Both remedies indicated potentials of use against arsenic intoxication.

The present study was undertaken to examine if microdoses of ultra-high diluted arsenic trioxide (a potentized homeopathic remedy, Arsenicum Album 200C, diluted 10−400 times) have hepatoprotective potentials in mice subjected to repeated injections of arsenic trioxide. Arsenic intoxicated mice were divided into: (i) those receiving Arsenicum Album-200C daily, (ii) those receiving the same dose of diluted succussed alcohol (Alc 200C) and (iii) another group receiving neither drug nor succussed alcohol. Two other control groups were also maintained: one fed normal diet only and the other receiving normal diet and Alc-200C. Toxicity biomarkers like aspartate and alanine aminotransferases, glutathione reductase, catalase, succinate dehydrogenase, superoxide dismutase and reduced glutathione contents were periodically assayed keeping the observer “blinded”. Additionally, electron microscopic studies and gelatin zymography for matrix metalloproteinases of liver tissues were made at day 90 and 120. Blood glucose, hemoglobin, estradiol and testosterone contents were also studied. Compared to controls, Arsenicum Album-200C fed mice showed positive modulations of all parameters studied, thereby providing evidence of protective potentials of the homeopathic drug against chronic arsenic poisoning.

Several homeopathic remedies, namely, Pulsatilla Nigricans (30th potency), Ceanothus Americanus (both mother tincture and 6th potency) and Ferrum Metallicum (30th potency) selected as per similia principles were administered to 38 thalassemic patients receiving Hydroxyurea (HU) therapy for a varying period of time. Levels of serum ferritin (SF), fetal hemoglobin (HbF), hemoglobin (Hb), platelet count (PC), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH), white blood cell (WBC) count, bilirubin content, alanine amino transferase (ALT), aspartate amino transferase (AST) and serum total protein content of patients were determined before and 3 months after administration of the homeopathic remedies in combination with HU to evaluate additional benefits, if any, derived by the homeopathic remedies, by comparing the data with those of 38 subjects receiving only HU therapy. Preliminary results indicated that there was a significant decrease in the SF and increase in HbF levels in the combined, treated subjects. Although the changes in other parameters were not so significant, there was a significant decrease in size of spleen in most patients with spleenomegaly and improvement in general health conditions along with an increased gap between transfusions in most patients receiving the combined homeopathic treatment. The homeopathic remedies being inexpensive and without any known side-effects seem to have great potentials in bringing additional benefits to thalassemic patients; particularly in the developing world where blood transfusions suffer from inadequate screening and fall short of the stringent safety standards followed in the developed countries. Further independent studies are encouraged.

In continuation of our short-term pilot studies reported earlier, results on certain toxicity biomarkers in volunteers who continued to take the potentized Arsenicum album 200C till 2 years are presented. Out of some 130 “verum”-fed volunteers of pilot study, 96 continued to take the remedy till 6 months, 65 till 1 year and 15 among them continued till 2 years. They provided samples of their urine and blood at 6 months, 1 year and finally at 2 years. None out of 17 who received “placebo” turned up for providing blood or urine at these longer intervals. Standard methodologies were used for determination of arsenic content in blood and urine, and for measurement of toxicity biomarkers like acid and alkaline phosphatases, alanine and aspartate amino transferases, lipid peroxidation and reduced glutathione and anti-nuclear antibody titers. Most of the volunteers reported status quo maintained after the improvement they achieved within the first 3 months of homeopathic treatment, in respect of their general health and spirit, and appetite and sleep. A few with skin symptoms and burning sensation, however, improved further. This was supported by the data of toxicity biomarkers, levels of all of which remained fairly within normal range. Therefore, administration of Arsenicum album 200C considerably ameliorates symptoms of arsenic toxicity on a long-term basis, and can be recommended for interim use, particularly in high risk remote villages lacking modern medical and arsenic free drinking water facilities. Similar studies by others are encouraged.

Crude Extract of Turmeric Reduces Hepato-Toxicity and Oxidative Stress in Rats Chronically Fed Carcinogens

Anisur Rahman Khuda-Bukhsh; Antara Banerjee; Raktim Biswas; Surajit Pathak; Naoual Boujedaini; Philippe Belon

The crude extract of turmeric (Curcuma longa L.; Zingiberaceae) is widely used in traditional systems of medicine like Ayurveda as a remedy for various diseases. Although various medicinal effects of its active principle, Curcumin, have been extensively studied in various animal models, there appears to be no systematic study on whether the crude extract can reduce hepato-toxicity and oxidative stress in rats induced by chronic feeding of p-dimethyl aminoazobenzene and phenobarbital, two known carcinogens of liver. Tests were conducted in experimental and controlled animals involving several widely accepted toxicity biomarkers at four fixation intervals, namely, 30, 60, 90, and 120 days. Results revealed an increase in activities of acid and alkaline phosphatases, alanine and aspartate amino transferases, gamma glutamyl transferase, lipid peroxidation and in levels of serum triglyceride, cholesterol, creatinine, urea, bilirubin, blood urea nitrogen and decrease in reduced glutathione content, catalase, glucose-6-phospahate dehydrogenase and blood glucose, HDL-cholesterol, albumin, and hemoglobin contents in carcinogen intoxicated rats. Most of these changes were reversed by the administration of crude extract of turmeric, indicating its hepato-protective potentials and ability to reduce oxidative stress in experimental rats. Further, from the analysis of expression of matrix metalloproteinases, p53 and Bcl-2 proteins in liver at 90 and 120 days (post tumor development), its anti-tumorigenic activity is also evident. The results would thus validate its traditional use in various ailments, particularly against liver disorders.
