OBJECTIVE To study the epidemiology, causes, and clinical course of Chinese herbal medicine-induced anticholinergic poisoning in Hong Kong. DESIGN Case series. SETTING Hong Kong. PATIENTS All case histories of Chinese herbal medicine-induced anticholinergic poisoning (with laboratory confirmation) recorded by the Hong Kong Poison Information Centre over a 93-month period were accessed for...

In this study, the activity of methanol extract of Prosopis cineraria (MPC) was evaluated in N-nitrosodiethylamine (DEN, 200mg/kg) induced experimental liver tumor in male Wistar rats. It was found that the administration of MPC (200 and 400mg/kg) effectively suppressed liver tumor induced by N-nitrosodiethylamine (DEN) as revealed by decrease in N-nitrosodiethylamine (DEN) induced elevated lev...

Sesbania mosaic virus (SeMV) is a positive stranded RNA virus belonging to the genus Sobemovirus. Construction of an infectious clone is an essential step for deciphering the virus gene functions in vivo. Using Agrobacterium based transient expression system we show that SeMV icDNA is infectious on Sesbania grandiflora and Cyamopsis tetragonoloba plants. The efficiency of icDNA infection was fo...

Intraspecific variation in pollen deposition and number of pollen tubes per style is rarely quantified, but is essential for assessing the occurrence of pollen limitation and pollen competition and their evolutionary implications. Moreover, pollen deposition, pollen tube growth, and the fate of fertilized ovules are rarely distinguished in field studies. Here we present such a study in eight na...

Extreme temperature events are projected to increase in frequency in a future climate. As successive extremes could occur more frequently, patches of vulnerable tundra vegetation were exposed to two consecutive heat waves (HWs) of 10 d each, with a 5-d recovery period in between. Surface temperatures during the HWs were increased approximately 6 degrees C using infrared irradiation sources. In ...

Background. Sesbania grandiflora has been traditionally used as antidiabetic, antioxidant, antipyretic, and expectorant and in the management of various ailments. Materials and Methods. The study evaluates the antidiabetic activity of methanolic extract of Sesbania grandiflora (MESG) in type 2 diabetic rats induced by low dose streptozotocine and high fat diet. Diabetic rats were given vehicle,...

Population genetic theory predicts that the efficacy of natural selection in a self-fertilizing species should be lower than its outcrossing relatives because of the reduction in the effective population size (N(e)) in the former brought about by inbreeding. However, previous analyses comparing Arabidopsis thaliana (selfer) with A. lyrata (outcrosser) have not found conclusive support for this ...

Schisandra grandiflora (Wall.) Hook. f. & Thomson (Schisandraceae: sect. Pleiostema), the specimens collected in Ha Giang, Cao Bang, and Vinh Phuc provinces, as a new recorded species for flora of Vietnam. A morphological comparison with related key to Vietnam was provided. description including details distribution habitat is supplied line-drawing.
