Peritoneal exudate cells (PEC) harvested from mice after i.p. injection of squalene-treated cell wall skeleton of Nocardia rubra (N. rubra-CWS) demonstrated vigorous cytolytic activity in vitro toward tumor target cells. Fractionation of these PEC by adherence to plastic dishes showed that the cytolytic activity in PEC was associated with an adherent phagocytic cell. Induction of the cytolytic ...

Plumeria rubra are commonly grown as ornamental plants in parks and home gardens because of their beautiful fragrant flowers of various color and size. Plumeria rubra is one of the plants which have been used in traditional medicine for many years. The plant is known to possess biological activities viz., antipyretic, antifungal, antiviral, analgesic, anticancer, antioxidative and hypolipidemic...

Ground bark and heartwood from Alnus rubra and Pseudotsuga menziesii were added to a muddy sediment from a small Oregon stream and incubated in situ. Carbon dioxide and methane production rates were increased by all amendments, the biggest increase being shown with A. rubra wood. Except for sediment amended with A. rubra wood, nitrogen fixation rates from all treatments (including the control) ...

As of now, within the lace bug family Tingidae (Cimicomorpha), only 1.5% of the species described have been cytogenetically studied. In this paper, male karyotypes of Stephanitis caucasica, Stephanitis pyri, Physatocheila confinis, Lasiacantha capucina, Dictyla rotundata and Dictyla echii were studied using FISH mapping with an 18S rDNA marker. The results show variability: the major rDNA sites...

Tilia species have been used in Asia, Europe and in America to treat anxiety and also for the treatment of colds and inflammation. The oxygen reactive species (ROS) (hydrogen peroxide (H2O2) and the superoxide anion (O2) are involve in the balance cell proliferation/death in lymphocytes. It was reported the presence of flavonoids in Tilia species which possess antioxidant properties. The aim of...

Introduction The inflorescences of Tilia americana var. mexicana are used as an infusion in Mexican traditional medicine due to their tranquilizing effects; however, pharmacological and phytochemical studies of the leaves are lacking. Objective In this research, the anxiolytic and sedative-like efficacy of the Tilia americana var. mexicana leaves was compared to that obtained with its infloresc...

Around the world, species from the genus Tilia are commonly used because of their peripheral and central medicinal effects; they are prepared as teas and used as tranquilizing, anticonvulsant, and analgesic agents. In this study, we provide evidence of the protective effects of organic and aqueous extracts (100 mg/kg, i.p.) obtained from the leaves of Tilia americana var. mexicana on CCl4-induc...
