Abstract Four isozymes, superoxide dismutase (SOD), polyphenol oxidase (PPO), malate dehydrogenase (MDH) and cytochrome oxidase (COD) were studied for identification of six herbal species (Curcuma L.). All the 37 study specimens produced a total of 168 polymorphism isozyme bands. The genetic distance coefficients (GS) varied from 0.08 to 0.54. The dendrogram, obtained according to the polymorphism isozyme bands by the UPGMA method with the software NTSYS–pc2.1, contributed to improve the resolution of phylogeny. From the dendrogram, it was possible to differentiate between the wild and cultivated specimens of C. longa, and within C. sichuanensis species. More >

Abstract Induced responses to herbivory are physical, nutritional, and allelochemical traits that change in plants following disturbances, and reduce the performance and/or preference of leaf tissues on herbivores. This study gave evidence to the induced defense theory through the simulated herbivory in Schima superba, one of common dominant trees in subtropical evergreen, broadleaf forests in southern China. Results showed that leaves damaged at the beginning of leaf expansion would develop into having a larger area, higher toughness and higher tannin concentrations, but a lower water content compared with control leaves. As a result, they experienced lower herbivory More >

Abstract An investigation of herbal medicinal teas from Western Cape, South Africa was conducted to assess the varieties of herbal teas used to treat various ailments. Each packet of medicinal tea is a blend of carefully selected four or more herbs which are commonly grown in the organic garden in an ancient valley near the southernmost tip of South Africa and some indigenous herbs picked up in the nearby mountains. The teas are specific for the diseased organ/s and also include the herbs to support and strengthen the systems serving the ailing organ/s. The study shows More >

Abstract Eleusine indica and Portulaca oleracea are two common weeds in peanut crops in southern Córdoba. Two chemicals are frequently used to control them, quizalofop for grasses and lactofen for dicots. The objective is to study the effects of quizalofop and lactofen on cuticle ultrastructure in E. indica and P. oleracea, respectively. In the lab, quizalofop was applied on E. indica and lactofen on P. oleracea. Three plant categories were analyzed in each species: 3, 1-2, and no tiller in E. indica, and 8, 6, and 2 nomophylls in P. oleracea. Leaf samples from both species were collected at 7 and 16 days post-application… More >

Abstract Background: Previous studies have shown that PADMA-28, a multicomponent, traditional Tibetan herbal plant preparation possesses a variety of beneficial effects on several experimental models of inflammatory and immune processes, including autoimmune diabetes and autoimmune encephalomyelitis. In humans, PADMA-28 attenuated the symptoms associated with intermittent claudications in atherosclerotic patients. Objective: To assess the effect of PADMA 28 on the immune system, e.g. cytokine (interleukins) production. Design: Cytokine production by human blood monocytes (derived from12 healthy donors) stimulated in vitro, either by endotoxin (LPS) from Salmonella typhi or by lipoteichoic acid (LTA) from group A Streptococci was… More >

Abstract Wheat (Triticum aestivum) transgenic plants of an important commercial cv (Oasis) was obtained with an efficient and short procedure. First, the optimum conditions for the embriogenic calli generation from inmature embryos with a high regeneration percentage were established. The transformation of calli was performed by high velocity microprojectile bombardment, using the pAHC25 plasmid, which contains the reporter gene β-glucuronidase (GUS) and the selectable BAR gene which confers resistance to the herbicide Basta. The transformations were confirmed by β-glucuronidase assay activity, PCR and Southern blot analysis. The efficiency of this procedure was high and similar to other More >
