Antimycobacterial activity of Populus alba leaf extracts
Tuberculosis (TB) is the principal cause of death worldwide due to an infectious agent,Mycobacterium tuberculosis. The search for new anti-TB drugs, especially from plants, is needed due to the emergence of multidrug-resistant (MDR), extensively drug-resistant (XDR) strains and nontuberculous mycobacteria (NTM). The aim of this study was to evaluate the antimycobacterial activity of the white poplar tree (Populus...

Histological, histochemical and immunohistochemical evaluation of the effects of seed and pulp of Carica papaya on the visual relay centres in animal model
The effects of the pulp and seeds of Carica papaya (Honey dew variety) on the visual relay centres in rats were investigated. Thirty rats were randomly grouped into three groups (A, B, and C) of ten rats each. Each of the rats in groups A, B and C were fed with 8.50 g of standard rat pellet, 8.50 g of 1:1 mixture of C. papaya pulp and the standard rat chow, and 8.50 g of 1:1 mixture of C....

Anti-inflammatory and antinociceptive activity of field-growth plants and tissue culture of Cleome spinosa (Jacq.) in mice
Methanol extracts (ME) of Cleome spinosa obtained from plants of natural growing areas (NP) and acclimatized plants (AP), as well as from the lipophilic mass containing beta-carotene (LMBC) produced from callus cultures were evaluated for their anti-inflammatory and antinociceptive potentials. These properties were studied using carrageenan-induced paw edema and acetic acid-induced writhing animal models. The...

Allelopathic effects of Paeonia decomposita on seed germination and protective enzymes activities of wheat
The root, stem and leaf aqueous extracts of Paeonia decomposita were assayed at 0.025, 0.050, 0.075 and 0.1 g ml-1 for their seed germination and early seedling growth of wheat. All aqueous extracts at all concentrations inhibited seed germination and seedling growth of wheat compared with the control, and the degree of inhibition increased with the incremental extracts concentration. Protective enzymes...

Correlation of trace elemental content in selected anticancer medicinal plants with their curative ability using particle induced x-ray emission (PIXE
Trace elemental analysis employing particle induced x-ray emission (PIXE) technique was carried out in some selected medicinal plants used in the preparation of anti-cancer drugs. The 3MV Pelletron Accelerator at Institute of Physics, Bhubaneswar, India was used for the present PIXE measurements. A beam of 3 MeV protons, collimated to a diameter of 2 mm, bombarded the samples placed at an angle of 45° to the beam...

Synthesis and elementary investigation of a new spectrophotometric reagent
The study is focused on the development of new spectrophotometric reagent for metal ion determination. The synthesis was through the condensation reaction between amino compounds and carbonyl compound. The spectrophotometric activities of the new reagent was studied using chromium (VI), cobalt (II), Hg (II), Cu(II) and Pb (II) respectively. The use of Jenway UV/VIS spectrophotometer (double beam) model 6505 was used to...
