Résumé

Adhatoda vasica Nees plants were grown in 50 earthen pots, which were divided into 5 batches A, B, C, D, and E. Of these A, B and C, D were arranged into two separate parallel pairs. One leaf of each plant of an adjacent pair was immersed in sterile tap water in a beaker. Adjacent beakers in each pair A B or C D were connected by polythene tubes containing wet cotton threads. One leaf of each plant of A was given heat shock by immersing a leaf in hot water for 5 min. One leaf of each plant of C was treated with Cantharis vesicatoria 200c. Batch E served as the unstressed and untreated control. One hour after heat shock or drug treatment all the leaves were harvested and their proteins were extracted by chilled protein extraction buffer. Proteins were separated by Fast Protein Liquid Chromatography (FPLC). Protein profiles of A, B and C, D showed marked similarity with respect to expression and repression of some proteins. It is concluded that the effect of heat shock and drug treatment is transmitted through water in the capillaries of cotton threads connecting the pairs of plants. It is assumed that heat shock or drug treatment altered locally the water structure in the leaves which was propagated through global network of water structure over the protein network in the whole plants, and from there to the interfacial water in the beakers and cotton threads. A homeopathic potency is thought to be specifically structured water which influences the water structure in the treated organism


Plantas Adhatoda vasica Nees foram cultivadas em 50 vasos de argila e divididos em 5 lotes A, B, C, D e E. Os lotes A, B e C, D foram arranjados em dois pares paralelos separados. Uma folha de cada planta dos pares adjacentes foi submergida num béquer com água corrente estéril. Os béqueres de cada par, A, B e C, D foram interconectados através de tubos de polietileno contendo fio de algodão umedecido. Uma folha de cada planta no lote A recebeu choque térmico através de imersão em água quente por 5 minutos. Uma folha de cada planta no lote C foi tratada com Cantharis vesicatoria 200c. O lote E foi utilizado como controle não submetido nem a estresse nem a medicação. Uma hora depois da aplicação de choque térmico ou tratamento medicamentoso, todas as folhas foram coletadas e suas proteínas foram extraídas através de tampão de extração de proteínas frio. As proteínas foram separadas através de cromatografia líquida rápida de proteínas (CLRP). Os perfis proteicos dos lotes A, B, C e D mostraram similaridade considerável quanto à expressão e repressão de algumas proteínas. Conclui-se que o efeito do choque térmico e do tratamento medicamentoso foi transmitido através da água nos capilares de fio de algodão conectando pares de plantas. Assume-se que o choque térmico e o tratamento medicamentoso alteraram localmente a estrutura da água nas folhas, que se propagou através da rede global da estrutura da água até a rede proteica nas plantas inteiras e dali para a água interfacial nos béqueres e fios de algodão. Considera-se que uma potência homeopática é água especificamente estruturada que influencia a estrutura da água no organismo tratado.

Résumé

The cell response of human HepG2 cells exposed to hypothermia with rewarming was analyzed. Ultrastructural findings in hypothermic stressed cells showed swollen mitochondria, dispersed chromatin, vacuoles and ring-shape nucleolar reorganization. These changes were coupled with significative differences in the induction of Hsp60, inducible Hsp70 and monomeric Hsf1 in all treated samples, but not in Hsc 70 expression. Cellular response to hypothermia could be associated with the synergistic induction of Hsp expression.


En este trabajo se analizó la respuesta celular de células HepG2 expuestas a hipotermia con posterior recuperación. Los hallazgos ultraestructurales en células sometidas a estrés hipotérmico incluyeron mitocondrias edematizadas, núcleos picnóticos, vacuolas y reorganización nucleolar en forma de anillo. Tales cambios están relacionados con diferencias significativas en la inducción de la expresión de Hsp60, Hsp70 inducible y Hsf 1 monomérico en todas las muestras tratadas, pero no de Hsc70. La respuesta celular a la hipotermia puede ser relacionada con la inducción sinergística de las Hsp.
