tetrandrine/hypoxia

To investigate the effect of Tetrandrine on pulmonary vascular morphology in rats with hypoxia pulmonary hypertension. We established the model of hypoxia pulmonary hypertension and observed the small pulmonary arterial morphologic changes under light microscope and electron microscope after the

OBJECTIVE To study the effects of tetrandrine (Tet) on the changes of NMDA receptor channels in cortical neurons induced by anoxia. METHODS Cell-attached configuration of patch-clamp techniques. Anoxia was produced by perfused cells with 95% N2 + 5% CO2 gassed bath solution. RESULTS During anoxia,

OBJECTIVE To investigate the effect of tetrandrine (Tet) on the collagen contents of lung tissues in rats with chronic hypoxic pulmonary hypertension. METHODS Using colorimetric method after oxidized by chloramine T to determine hydroxyproline contents of lung tissues and extrapulmonary arteries,

Metastasis remains the most deadly aspect of cancer and still evades direct treatment. Thus, there is a great need to develop new treatment regimens to suppress tumor cells that have escaped surgical removal or that may have already disseminated. We have found that tetrandrine (TET) exhibits

OBJECTIVE The mechanism that tetrandrine (Tet) reduces hypoxic pulmonary hypertension was investigated METHODS 30 Wistar rats were divided into normal control group, pulmonary hypertension group and tetrandrine-treated group. Total calcium conteins and calmodulin activity in lung tissue were

The aim of this study was to explore the effect and action mechanisms of intermittent hypoxia on the production of testosterone both in vivo and in vitro. Male rats were housed in a hypoxic chamber (12% O(2) + 88% N(2), 1.5 l/ml) 8 h/day for 4 days. Normoxic rats were used as control. In an in vivo

OBJECTIVE To evaluate effect of tetrandrine (Tet) on chronic hypoxic pulmonary by observing expression of bFGF in lung tissue of rat with chronic hypoxic pulmonary hypertension. METHODS 30 rats were divided into 3 groups: hypoxia group, hypoxia + Tet group and control group. On the 21st day of

OBJECTIVE To investigate the effect of tetrandrine (Tet) pulmonary targeting microspheres on hypoxic pulmonary hypertension and its selective role on pulmonary circulation. METHODS Tet pulmonary targeting microspheres were synthesized by spraying desiccation, the content of tetrandrine in pulmonary

OBJECTIVE To assess the effect of tetrandrine (Tet) pulmonary targeting microspheres on hypoxic pulmonary hypertension and evaluate its selective action on pulmonary circulation. METHODS Twenty rats were exposed to hypoxic conditions for 3 weeks. Ten rats were used as normoxic controls. We

Previous studies have linked neuronal cell death with changes of intracellular Ca(2+)([Ca(2+)](i)) homeostasis. Such changes of [Ca(2+)](I) has been noticed in various neurodegenerative models. It has also been suggested that K(+)channel, such as large conductance Ca(2+)-activated K(+) channel (BK),

The present study investigated the effect of tetrandrine on lung cancer cell growth and apoptosis, and its possible underlying molecular mechanism. A549 human lung cancer cells were incubated with between 2.5 and 10 µM tetrandrine for 12, 24 and 48 h, following which the effect of tetrandrine on

Tetrandrine (TET), a bisbenzylisoquinoline alkaloid has been used for the treatment of cardiovascular diseases and hypertension. This study was to investigate whether tetrandrine exerts cardioprotection in ischemia-reperfusion (I/R) injury and the mechanisms involved. The cardioprotection effect and
