This study was conducted to obtain acute information of the oral dose toxicity of DHU001, a polyherbal formula in male and female mice. In order to calculated 50% lethal dose (LD50) and approximate lethal dose (LD) , test material was once orally administered to male and female ICR mice at dose levels of 2000, 1000, 500, 250 and 0 (vehicle control) ml/kg (body weight) . The mortality and change...

Primary powders of Bacillus sphaericus strain S2 isolated from soil samples in Brazil, and strain 2362 were produced in a 14 liter fermentor. Growth patterns and sporulation observed in three trials with strains S2 and 2362 in the fermentor were similar. Second-instar larvae of Culex quinquefasciatus, Anopheles albimanus, Anopheles quadrimaculatus, and Aedes aegypti exposed for 48 hr to strain ...

Development of biomarkers capable of estimating absorbed dose is critical for effective triage of affected individuals after radiological events. Levels of cell-free circulating miRNAs in plasma were compared for dose-response analysis in non-human primates (NHP) exposed to lethal (6.5 Gy) and sub-lethal (1 and 3 Gy) doses over a 7 day period. The doses and test time points were selected to mim...

The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. T...

In view of suggested anti diabetic potential, effect of aqueous and cold extracts of Terminalia Catappa Linn (Combretaceae) leaves, on fasting blood sugar levels and serum biochemical analysis in alloxan-induced diabetic rats was investigated. All the extracts of Terminalia Catappa produced a significant anti diabetic activity at dose levels of 1/5th of their lethal doses. Concurrent histologic...

Mice inoculated either subcutaneously (s.c.) or intradermally (i.d.) with a sublethal dose of Francisella tularensis LVS are immune to a lethal intraperitoneal (i.p.) or intravenous (i.v.) challenge of LVS. Here, we show that this immunity developed quite rapidly: mice given a sublethal dose of live LVS s.c. or i.d. (but not i.v.) withstood lethal i.p., i.v., or i.d. challenge as early as 2 day...
