ABSTRACT
White mold disease, caused by fungus Sclerotinia sclerotiorum (Lib.) de Bary., is a disease hard to control due to the high amount of sclerotia produced, which guarantees its survival in the soil for years leading to significant yield losses. Alternative techniques to control the pathogen have been researched, including homeopathy. The present work aimed to evaluate the in vitro antifungal effect of homeopathic medicines on S. sclerotiorum mycelial growth. Homeopathic medicines Sulphur, fungal sclerotium Nosode and Calcarea carbonica, in 30CH, 200CH and 1000CH dynamizations were tested. Assays were carried out in a completely randomized design, with four repetitions. Experiments were performed through the addition of homeopathic medicines on the surface of plates containing culture medium, followed by insertion of a disc containing fungus mycelia and incubation. Control treatment received no homeopathic medicine. The mycelial progression was monitored by seven halo diameter measurements during experiment period. All homeopathic medicines tested and their dynamizations were able to inhibit partially the development of the fungus. Calcarea carbonica at the dynamization of 1000 CH showed the best inhibitory effect on S. sclerotiorum, which under its effect produced a mycelial halo 40% smaller than the control treatment.

OBJECTIVE@#Prolonged use of nonsteroidal anti-inflammatory drugs is associated with severe side effects and toxicity. Therefore, we studied the anti-inflammatory role of Calcarea carbonica which had minimal toxicity at the low doses.@*METHODS@#THP-1 human mononuclear cells were treated with C. carbonica to evaluate the 50% cytotoxicity concentration (CC) and 50% effective concentration (EC). Cell survival was evaluated in lipopolysaccharide-stimulated C. carbonica-treated cells. Nitric oxide (NO) and tumor necrosis factor-α (TNF-α) were measured to evaluate the anti-inflammatory activity of C. carbonica. Cyclooxygenase-2 (COX-2) protein expression was determined by Western blotting analysis, and the interaction of C. carbonica with the COX-2 protein was evaluated using molecular docking simulation.@*RESULTS@#The CC and EC of C. carbonica were found to be 43.26 and 11.99 µg/mL, respectively. The cell survival assay showed a 1.192-fold (P = 0.0129), 1.443-fold (P = 0.0009) and 1.605-fold (P = 0.0004) increase in cell survival at 24, 48 and 72 h after initiating C. carbonica treatment, respectively. C. carbonica-treated cells showed a reduction in NO levels by 2.355 folds (P = 0.0001), 2.181 folds (P = 0.0001) and 2.071 folds (P = 0.0001) at 24, 48 and 72 h, respectively. The treated cells also showed a reduction in TNF-α levels by 1.395 folds (P = 0.0013), 1.541 folds (P = 0.0005) and 1.550 folds (P = 0.0005) at 24, 48 and 72 h, respectively. In addition, a 1.193-fold reduction (P = 0.0126) in COX-2 protein expression was found in C. carbonica-treated cells. The molecular docking showed interaction of C. carbonica with the phenylalanine 367 residue present in active site of Cox-2.@*CONCLUSION@#C. carbonica exhibited anti-inflammatory properties in lipopolysaccharide-stimulated cells by significantly reducing NO production and TNF-α level through downregulation of the COX-2 protein. This effect is probably mediated through interaction of C. carbonica with the phenylalanine 367 residue present in active site of Cox-2.

ABSTRACT
OBJECTIVE: To decipher the nature of water structure in two ultrahigh diluted (UHD) homeopathic drugs by Laser Raman Spectroscopy. METHOD: Two homeopathic drugs Calcarea carbonica (Calc.) and Sepia officinalis (Sep.) in 8cH, 202cH, and 1002cH and their diluent medium 90% ethanol in 8cH and 202cH were used in the present study. Laser Raman spectra of all the samples were obtained in the wave number region of 2400 4200 cm-1. The intensity ratio at vibration frequencies between 3200 and 3420 (R1) and that between 3620 and 3420 (R2) were calculated for each UHD of the samples. RESULTS: The spectra show a marked difference in intensities in the stretching vibrations of CH and OH groups of all the samples. R1 values for three UHDs of Calc. and Sep. show negative and positive relationships, respectively. In the case of R2 values, the relationship in three UHDs is 81002 for Calc., and 8> 202 < 1002 for Sep. In the case of control (ethanol UHDs) both R1 and R2 show a negative relationship. CONCLUSION: R1 denotes a relative number of OH groups with strong and weak hydrogen bonds. R2 indicates the relative number of OH groups with broken and weak H-bonds. Therefore, the UHDs of the two drugs and the control are different from each other with respect to hydrogen bond strength of OH groups and the number of free OH groups or non-hydrogen bonded water molecules.

El dolor torácico es un motivo de consulta muy frecuente tanto en servicios de urgencias como en consulta externa, se estima que aproximadamente el 20% de las consultas de adultos no quirúrgicas en un servicio general de urgencias, corresponde a dolor torácico. La mayoría de ellos (85 a 90%) no se deben a síndrome coronario agudo (o infarto agudo de miocardio) o a otra potencialmente mortal. No encontramos informada en la literatura médica, una propuesta para el manejo de estos pacientes con homeopatía. Se revisó en medicinas internas y semiologías las diversas formas de presentación de dolor torácico, acorde con varios orígenes: Coronario, Gastroesofágico, Costocondral (Reumático) o Pleural. Seguidamente, se investigó en un repertorio digital (Radar 7) los medicamentos que mejor puntuaban según los síntomas más frecuentes, pretendiendo abarcar la totalidad sintomática del paciente. Se hizo una revisión y resumen de varias materias médicas de 20 medicamentos mejor puntuados y finalmente se elaboró un algoritmo con dos de los síntomas más característicos en las diversas modalidades de dolor torácico. Los medicamentos analizados fueron: Acónitum, Argentum Nitricum, Arsénicum Album, Árnica, Aurum Metálicum, Bryonia, Cactus Grandiflorus, Calcárea Carbónica, Carbo Vegetábilis, Causticum, Digitalis, Kali Carbónicum, Nux Vómica, Phosphorus, Spongia Tosta y Sulphur. A modo de ejemplo, en el dolor torácico de tipo opresivo o anginoso acompañado de angustia y temor a la muerte, los medicamentos más puntuados son: Acon, Dig, Arn y Cact.
