Lady's finger plants (Hibiscus esculentus), grown in pots, were inoculated with the second-stage larvae (76+/-6) of root-knot nematodes Meloidogyne incognita, starting 7 days later they were treated with Cina 30c, Santonin 30c or Ethanol 30c by foliar spray for 10 consecutive days. The drugs in 90% ethanol were diluted with distilled water 1:1000 before application on plants. Thirty days after the last treatment the plants were uprooted. Cina 30c and Santonin 30c reduced nematode infestation of plants significantly in terms of root-gall number, root-protein content and nematode population in roots. Santonin 30c reduced root water content. Santonin 30c may have influenced the water channel proteins of root tissues thereby altering the water contents of roots. The reduced water content in roots might have adversely affected the root-knot nematodes and thus reduced nematode infestation. Ethanol 30c also has some effect on treated plants.

Objective: The aim of this study was to determine whether potentized homeopathic drugs and their diluent media differ from each other with respect to their Fourier transform infrared (FTIR) spectra., Design: FTIR spectra of Nux vomica 30C, Lycopodium 30C, Santonin 30C, Cina 30C, Cina 206C, Cina 1006C, and their diluent media 90% ethanol and Ethanol 30C were obtained in the wave number range of 2000-1000 cm1 at 20 degrees C. Potassium bromide powder soaked with the potencies, pressed into pellets, and air dried were used to measure the spectra. Because water structures in homeopathic potencies are thought to carry specific information on drug molecules and because O-H bending vibrational band (v2) exclusively belongs to water, the study was restricted to the bands in that wave number region. Alcohol has no absorption in the O-H bending region., Results: The potencies were found to differ from each other and their diluent media in the number of v2 bands, their wave number (cm1), shape, and half-width (cm1) of the bands., Conclusions: The number and other characteristics of the v2 band represent the number of hydrogen-bonded water species and their hydrogen-bonding strength, respectively. The potencies and their diluent media therefore differ from each other in the number of hydrogen-bonded water species and their hydrogen-bonding strength. The observation that KBr pellets soaked with a potentized drug retains its specific spectral absorption properties simply confirms that medicated sucrose globules, used in homeopathic dispensing, are capable of retaining the therapeutic properties of the drug.

Background: Trichinellosis caused by the gastrointestinal nematode Trichinella spiralis occurs in humans, domestic animals and wild animals. It is difficult to control the muscle phase of the parasite. Homeopathic drugs such as Cina and Santoninum have anthelmintic properties. We have observed that in material doses, the homeopathic drug Podophyllum also has nematotoxic properties. We have also observed that homeopathic potency can influence the water permeability of cells., Objective: The purpose of this study was to investigate whether potentized homeopathic drugs such as Cina 30, Santoninum 30 and Podophyllum mother tincture can affect the muscle phase of the parasite T. spiralis in mice. Another objective was to see whether trichinellosis and its treatment with the 3 named homeopathic drugs could alter the water content in the muscle tissue of mice., Materials and Methods: Cina 30 and Santoninum 30 were prepared from the mother tincture of the flowering tops of Artemisia nilagirica and its active principle santonin, in each case by successive dilution (1:100) with 90% ethanol and sonication in 30 steps following the single glass method (K30). Ethanol 30 was prepared by successive dilution of 90% ethanol with 90% ethanol (1:100) followed by sonication in 30 steps. In each step, the dilution was sonicated at 20 KHz for 30 s. We have observed before that sonication is a more uniform, measurable and effective process of mechanical agitation of a liquid than manual succussion. Experimentally infected mice were orally treated with an aqueous Podophyllum suspension at 60 mg/kg/day. Each potentized drug was diluted 1:20 with distilled water and administered orally at 0.05 ml/mouse/day. Each mouse was inoculated with T. spiralis larvae at a dose of 200 larvae/mouse by esophageal intubation. Treatment was started on day 7 post-infection and continued for 120 days. After completion of treatment, the mice were sacrificed and the larvae were extracted from muscles by HCl-pepsin digestion. The water content of the muscles was measured by determining the difference between fresh weight and dry weight of the tissue., Results: Podophyllum Theta, Cina 30 and Santoninum 30 reduced the larval population in the studied mice by 68.14%, 84.10% and 81.20%, respectively, as compared to the untreated control group. Ethanol 30 achieved no significant reduction in the larval population compared to the untreated control group. The water content of the muscle tissue in the untreated control group and the Podophyllum-treated groups was significantly higher than in the Ethanol 30-, Cina 30- and Santoninum 30-treated groups., Conclusions: (1) Podophyllum Theta, Cina 30 and Santoninum 30 were effective in the muscle phase of T. spiralis infection and significantly reduced the larval population in the treated mice. The potencies were more effective than the mother tincture, an effect which was not due to the medium ethanol. (2) The potencies significantly reduced the water content of the muscle tissue which might have affected the larvae. The effect of Podophyllum Theta might be due to the direct toxic effect of the drug on the larvae.

Objectives: The primary biomolecular target of a homeopathic potency is unknown. If it is a plasma membrane protein such as water-channel protein, the drug would alter water permeation in cells. Therefore, the objective is to see if potentized homeopathic drugs like Mercuric chloride 30c and Nux vomica 30c could alter permeation of water through the erythrocytes of a fresh water fish under acute ethanol intoxication., Location: The work was carried out in the Zoology Laboratory of Visva Bharati University, Santiniketan, West Bengal, India., Subject: Live freshwater catfish., Design: Erythrocytes collected from fish with and without ethanol intoxication were incubated in distilled water at 30 degrees C for 30 minutes with Ethanol 30c (control), Merc cor 30c (test 1), and Nux vomica 30c (test 2). Merc cor 30c and Nux vom 30c were prepared by successive dilution of the respective mother tinctures with 90% ethanol (1:100) followed by sonication at 20 kHz for 30 seconds in 30 steps. Ethanol 30c was prepared in the same way from 90% ethanol diluted with 90% ethanol. In another experiment, fish were pretreated with Ethanol 30c and Nux vom 30c followed by ethanol injection at 2 g/kg of body weight. Then their erythrocytes were tested in vitro with the same potencies. After centrifugation of blood samples, fluid part was removed, erythrocyte pellets dried in a BioChemical Oxygen Demand (BOD; Atlas Surgical, New Delhi, India) incubator at 90 degrees C for 12 hours and intracellular water content measured., Results: Red blood cells (RBCs) from ethanol-injected fish permeated more water than those from normal fish. Water permeation was enhanced with Merc cor 30c and Nux vom 30c. RBCs from fish pretreated with Nux vom 30c imbibed more water in in vitro treatments than those from fish pretreated with Ethanol 30c., Conclusion: Because water channel proteins or aquaporins are mainly responsible for water transport through the plasma membrane of RBCs, it is thought that potentized drugs interact with these proteins, thereby facilitating water influx in the cells.

Objectives: To see whether Strychnos nux-vomica extract (mother tincture [MT]), its potency Nux 30c, and its principal alkaloid, strychnine, could reduce voluntary ethanol intake in rats. To analyze the solution structure of Nux MT, Nux 30c, 90% ethanol, and ethanol 30c by means of electronic (ES) and nuclear nuclear magnetic resonance (NMR) spectra., Design: Potentially alcoholic rats were first given 20% ethanol and then kept on a two-choice bottle, one with 20% ethanol and another with tap water. These rats were given the following oral treatments for 15 days: group 1, control; group 2, strychnine at 0.36 mg/kg per day; group 3, ethanolic extract of S. nux-vomica seeds (Nux MT) at 3.6 mg/kg per day; and group 4, Nux 30c at 0.05 mL/d per rat. Nux 30c was prepared by successive dilution of Nux MT and 90% ethanol (1:100) and sonication at 20 kHz for 30 seconds in 30 steps., Results: Both Nux MT and Nux 30c significantly reduced ethanol intake and increased water intake in rats. ES of two dilutions of Nux MT and Nux 30c showed intersections at more than one point suggesting existence of molecular complexes. ES of Nux MT in CCl4 showed a red shift when 90% ethanol was added indicating molecular complexation and charge transfer interaction between ethanol and Nux compounds. NMR spectra of Nux MT, 90% ethanol, ethanol 30c, and Nux 30c indicated a change in solution structure of the medium (90% ethanol) of Nux 30c., Conclusion: Nux MT and Nux 30c could reduce ethanol intake in rats. The altered solution structure of Nux 30c is thought to mimic Nux MT and produce ethanol aversion in rats.

Acaciaside A and B, two acylated triterpenoid bisglycosides isolated from the funicles of Acacia auriculiformis, are known to have antihelmintic activity. Since the saponins contain a conjugated unsaturated system that is highly susceptible to peroxidation, we investigated the interaction of saponins and membrane using rat liver microsomes as our model. Microsomal membranes were incubated with saponins at 30 degrees C for 2 hr. Following incubation, lipid peroxidation was measured in terms of malondialdehyde and conjugated diene. Our results showed that incubation of microsomal membranes with saponins increased both malondialdehyde and conjugated diene. The results suggest that in our model, saponins enhance the membrane lipid peroxidation.

The cestocidal activity of Acacia auriculiformis was evaluated using rats each harbouring a single adult worm of Hymenolepis diminuta. The ethanol extract (300 mg/kg/day) and the saponins (200 mg/kg/day) obtained from the funicles of A. auriculiformis, were administered orally to two groups each of 10 rats, respectively, on day 20 after oral inoculation with a single cysticercoid of H. diminuta. Adult worms were expelled within 5 days from rats treated with the ethanol extract and within 3 days from those treated with saponins. No appreciable side effects were observed in the treated rats.

The active principle, isolated from the funicles of A. auriculiformis, consisted of two triterpenoid saponins, acaciaside A and acaciaside B which killed in vitro 97% microfilaria of Setaria cervi in 100 min at 4mg/ml concentration and 100% of adults in 35 min. The drug, when administered orally at 100 mg/kg on rats, in which S. cervi adults were implanted intra-peritoneally, increased the blood mf count by 1.5-fold after the first phase of treatment for 10 days. Following the third phase of treatment and thereafter, the mf density was reduced by more than 80%. No toxic effect of the saponins was observed in rats. The rise in mf count indicated that the drug induced a very high physiological stress on the adult worms which increased the rate of discharge of the mf before impending death. The treated rats on autopsy did not show any adult worms.

Dogs, naturally infected with Dirofilaria immitis, were treated with the residues of the alcoholic extracts of the rhizomes of Zingiber officinale (ginger). Twelve subcutaneous injections of the extract given at 100 mg/kg reduced microfilarial concentration in blood by a maximum of 98%. Fifty five days after the last injection there was 83% reduction in microfilarial concentration suggesting partial destruction of adult worms. Half of the treated dogs showed some lethargy at the beginning of treatment possibly due to the mass annihilation of microfilariae in blood.

Alpha adrenergic receptors are important in motor control. Adrenergic drugs reportedly modulate the catalepsy caused by other agents, such as opiates and neuroleptics. We tested a variety of adrenergic agonists and blockers in a nondrug, mouse model of catalepsy. A major cataleptic effect was produced by both alpha agonists, phenylephrine (0.5 to 3 mg/kg, IP) and clonidine (0.5 to 2 mg/kg), and this catalepsy was antagonized by pretreatment with both of the respective antagonists, phenoxybenzamine (alpha-1) and yohimbine (alpha-2) (p less than 0.0001). The mixed beta agonist, isoproterenol (2 mg/kg), appeared to have a minor cataleptic effect, and this was abolished by beta antagonist. Open-field locomotor scores during the same treatments revealed that catalepsy and hypokinesia are dissociable.

Aqueous extracts of Ocimum sanctum and O. basilicum leaves contained compounds that killed Meloidogyne incognita larvae in 160 min. Thin layer and gas-liquid chromatography, and infrared spectrophotometry indicated that the essential oils eugenol and linalool were the active nematicidal compounds.

C. elegans responds directionally to a DC current. The response may be to the anode or cathode, depending on the current, potential difference, and ion concentration of KC1, Tracks of the responding nematodes show that electrotaxes are genuine orientation phenomena. The directional movement is not due to the passive movement of nematodes or to the influence of currents on the muscular physiology; electrotaxes are mediated sensorily. Details of the response are described.

The four homoeopathic drugs, Gelsemium, Cannabis Indica, Graphites and Agaricus Muscarius, administered orally in 30th and 200th potencies on white rats, enhanced restraint-induced catalepsy in a similar manner to the two standard drugs pilocarpine and haloperidol (IP injection at 5 mg/kg). All the drugs tested differed from each other in the duration of cataleptogenic effect, which was more prolonged with Cannabis, Graphites and Agaricus than with Gelsemium and the two non-homoeopathic drugs used. The 200th potency of any homoeopathic drug tested acted longer than its 30th potency.

A few drugs affecting the dopaminergic system were tested for cataleptic effects in mice, and compared with an orally administered plant extract, Agaricus Muscarius 30. Haloperidol, Agaricus, and a low dose of apomorphine (0.3 mg/kg) were cataleptic. Paralleling previously reported results with haloperidol, the Agaricus catalepsy was potentiated by the mixed agonist, apomorphine (5 mg/kg), and by the selective D2 agonist, bromocriptine (5 mg/kg) and was reversed by the D1 agonist, SKF 38393. Naloxone also reversed Agaricus catalepsy, suggesting an involvement of opiate as well as dopaminergic mechanisms. All conditions that produced catalepsy also suppressed spontaneous locomotion, except for Agaricus 30 given alone. These experiments also compared cataleptic drugs by the published "pinch" method that involves repeated trials with a new single-trial method. Catalepsy was produced by the same drugs in both tests, but the single-trial method was more sensitive for disclosing the catalepsy induced by weaker cataleptogens.

Water decoction of the leaves of Andrographis paniculata killed in vitro the microfilaria of Dipetalonema reconditum in 40 min. Three subcutaneous injections of the extract into infected dogs at 0.06 ml per kg body-weight reduced the number of microfilariae in blood by more than 85%. The larvae were not totally eliminated with more infections but the reduced microfilarial level persisted. No toxic effect of the extract was observed in rabbits. The treated dogs became lethargic initially for a week, probably due to the mass killing of microfilariae.
