Essential oil has performed a variety of indirect services used as insect/pest repellent. The present study investigated the acute and subchronic toxicity of eucalyptus oil emulsion in water (EOE). In addition, we conduct safety pharmacology evaluation of EOE to supplement the toxicity tests and provide a basis for a comprehensive understanding of the toxicity of EOE. Acute administration of EO...
Acute and subchronic toxicities of Chantaleela recipe were studied in both male and female rats. Oral administration of the extract at a single dose of 5,000 mg/kg body weight (5 females, 5 males) did not produce signs of toxicity, behavioral changes, mortality or differences on gross appearance of internal organs. The subchronic toxicity was determined by oral feeding the test substance at the...
OBJECTIVES Ocimum basilicum L. is widely used in folk medicine of many countries including . Both O. basilicum and its oil extract have received considerable attention for their potential medicinal properties, but there are a few reports about possible toxicity of this plant. Therefore, in the present study, acute and subchronic toxicity of O. basilicum hydroalcohlic extract have been evaluated...
A recombinant lactase was expressed in Pichia pastoris, resulting in enzymatic activity of 3600 U/mL in a 5 L fermenter. The lactase product was subjected to a series of toxicological tests to determine its safety for use as an enzyme preparation in the dairy industry. This recombinant lactase had the highest activity of all recombinant strains reported thus far. Acute oral toxicity, mutagenici...
This study was carried in order to determine short-term (acute) and long-term(subchronic) effects of Melastomastrum capitatum leaf methanol extract in the management and treatment of certain diseases in traditional and complementary medicines by many villages in Mambila Nigeria. Acute and subchronic toxicities were carried out in accordance with the Organization for Economic Cooperation and D...
The aim of the study was to investigate the effects of subchronic exposure of zebrafish (Danio rerio) to a fluoroquinolone norfloxacin, using selected oxidative stress parameters as a target. Toxicity tests were performed on zebrafish according to the OECD Guidelines number 203 and number 215. In the Subchronic Toxicity Test, a significant (P < 0.01) increase in the activity of glutathione pero...
The present study evaluated the antioxidant activity and potential toxicity of 50% methanolic extract of Orthosiphon stamineus (Lamiaceae) leaves (MEOS) after acute and subchronic administration in rats. Superoxide radical scavenging, hydroxyl radical scavenging, and ferrous ion chelating methods were used to evaluate the antioxidant properties of the extract. In acute toxicity study, single do...
