Objective: To evaluate the acute toxicity studies of methanolic seed extract of Tectona grandis in albino mice. Method: The present study has been carried out to evaluate the adverse and hazardous effects of methanolic seed extract of Tectona grandis in albino mice through oral route. Acute oral toxicity of methanolic extract was carried out in two phases. In first phase, a single dose of 10, 50, 100, 500 and 1000mg/kg (dissolved in water) body weight in test group, while mice in control group received normal saline was administered. All the animals were individually studies for the mortality, wellness parameters and body weight for 14 days. The experiment was performed under OECD guidelines 423. No mortality or any significant physiological changes in the animals were observed up to 1000mg/kg bodyweight. The experiment was again repeated for second phase with a single doses of 1000, 1250, 1500 and 2000 mg/kg. Mortality was found at 1250 mg/kg. Therefore LD50 of the extract was estimated to be more than 1000mg/kg body weight. Finally, administration of a single dose of 10, 50, 100, 500, 1000 mg/kg of the extract did not showed any significant differences in food and water consumption and other behavioral changes. The extract starts showing toxicity at a dose of 1250 mg/kg body weight. Conclusion: The analysis of these results with the information of signs, behavior and health monitoring leads to the conclusion that the oral administration of T.grandis methanolic seed extract for 15 days does not cause acute toxicity. But, higher doses on long term administering can cause considerable toxicity.

Abstract Objectives “Bignay” (Antidesma bunius), “lipote” (Syzygium polycephaloides) and “duhat” (Syzgium cumini) are indigenous berries in the Philippines that are known to contain high antioxidant properties and other health-promoting and disease-preventing compounds. However, oral toxicity studies on these berries are not yet explored. Hence, this study evaluated the acute oral toxicity of these berries in freeze-dried forms using 6-week old ICR mice following the OECD guidelines 425 (up and down method). Methods Treatment groups were administered with freeze-dried powders of “bignay”, “lipote” and “duhat” reconstituted in distilled water at various doses: 55 mg/kg body weight (BW), 175 mg/kg BW, 550 mg/kg BW, 2000 mg/kg BW and 5000 mg/kg BW while control group was administered with distilled water. Body weight, feed and water intake were obtained daily. Biochemical profiles were measured prior to administration of reconstituted berries at day 1 and prior to euthanasia. Toxicity, morbidity and mortality cases were observed daily. Euthanasia and necropsy were performed to check for gross organ abnormalities. Results Mice that received the different concentrations of “bignay”, “lipote” and “duhat” had normal feed and water consumption and gained weight during the test period. No clinical and behavioral signs of toxicity were observed and there was zero morbidity and mortality. Post-mortem evaluation showed no lesions on various organs examined. Blood ALT, BUN and creatinine levels were within normal published values. Conclusions These results show that different concentrations of freeze-dried “bignay”, “lipote” and “duhat” are non-toxic using ICR mice and therefore have high potential to be developed into food supplements and nutraceuticals.

Introduction: Kajjali is considered as the base in maximum Rasa Yogas (Herbo-mineral formulations). Shwasakuthara Rasa (SKR) is a well-known herbo-mineral formulation indicated in different kinds of Shwasa (respiratory diseases) and Kasa (cough) having Kajjali as a base ingredient. The present study is to evaluate the acute toxicity and anti-tussive activity of SKR one prepared with Kajjali (SKR1) and another without Kajjali (SKR2) in sulphur dioxide induced cough model in albino mice. Materials and Methods: Acute toxicity study was carried as per the OECD 425 guideline in wistar female rats. Anti-tussive activity was carried out against sulphur dioxide-induced cough reflex in mice. Results: Animals did not manifest any signs of toxicity and mortality at the dose of 2000mg/kg body weight, orally. Both test drugs (32.5 mg/kg, po) showed significant reduction in cough reflexes compared with control. SKR1 showed pronounced anti-tussive activity followed by SKR2 when compared to control group. Conclusion: The presence of Kajjali in the formulation is safe on acute administration and further enhances anti-tussive activity of the formulation may be due to increasing bioavailability of Ayurvedic formulation.

Medicinal plants are used throughout the world and the World Health Organization supports its use by recommending quality, safety and efficacy. Minthostachys mollis is distributed in the Andes of South America and is used by the population for various diseases. While studies have shown their pharmacological properties, the information about their safety is very limited. Then, the goal of this research was to determine the acute oral toxicity and in repeated doses during 28 days of Minthostachys mollis essential oil (Mm-EO) in rats. For the acute toxicity test two groups of rats, of three animals each, were used. Each group received Mm-EO in a single dose of 2000 or 300 mg/kg of body weight. For the repeated dose toxicity test, four groups of 10 rats each were used. Doses of 100, 250 and 500 mg/kg/day were used, one group was control. With the single dose of Mm-EO of 2000 mg/kg of body weight, the three rats in the group showed immediate signs of toxicity and died between 36 and 72 hours. In the lung, inflammatory infiltrate was observed, predominantly lymphocytic with severe hemorrhage and presence of macrophages with hemosiderin. In the repeated dose study, male rats (5/5) and female rats (2/5) died at the dose of 500 mg/kg/day. The body weight of both male and female rats decreased significantly with doses of 250 and 500 mg/kg/day. The serum levels of AST and ALT increased significantly and the histopathological study revealed chronic and acute inflammatory infiltrate in the lung; while in the liver was observed in 80% of the cases (24/30) mild chronic inflammatory infiltrate and in some of those cases there was vascular congestion and in one case cytoplasmic vacuolization. The Mm-EO presented moderate acute oral toxicity, while with repeated doses for 28 days; there was evidence of toxicity, in a dose-dependent manner, mainly at the hepatic level.

Endogen phospholipids play a major role in determining the structure and nature of cell membranes. A deficiency of phospholipids in cellular membranes makes it almost impossible for the cell membrane to perform its function as a selective barrier between what passes in and out of the cell. Polyenylphosphatidylcholine chemical structure corresponds to that of endogen phospholipids, but it possesses functional superiority because of its content of unsaturated fatty acids. Polyenylphosphatidylcholine integrates in the cell membrane and organelle systems while becoming their constitutive elements. A healthy cell membrane leads to healthy cells and then healthy tissue and then to healthy organs or body systems and finally, healthy bodies and minds. For a long time, polyenylphosphatidylcholine in combination with vitamins has been used in the treatment of numerous health problems such as liver diseases, dyslipoproteinaemias and different intoxications with consequent liver failure. The main aim of toxicology studies is evaluation of the toxic potential and risks of human exposition to the substance. According to the Organization for Economic Cooperation and Development (OECD) acute oral toxicity refers to those adverse effects occurring following oraladministration of a single dose of a substance or multiple doses given within 24 hours. LD50 (median lethal dose), oral, is a statistically derived single dose of a substance that can be expected to cause death in 50 per cent of animals when administered by the oral route. Our acute toxicity study was performed on albino Wistar rats. Animals were randomised in three experimental and one control group, each of 5 males and 5 females. Study was based on the administration of a single oral dose of the test substance (polyenylphosphatidylcholine) to each experimental animal. There were three dose-levels of the test substance: 300, 500 and 1000 mg/kg. Test substance administration day was the first day of the observation period that lasted 14 days. Control animals were given milk vehicle. At the end of the study, no statistically significant differences between experimental and control animals were observed concerning the recorded parameters: body weight, respiratory rate, tremor, faeces and phonation quality, indicating the absence of the test substance acute toxicity.

Objectives: The present study was carried out to evaluate the hydroalcoholic extract of Mucuna pruriens (HAMP) seeds for its acute oral toxicity in albino rats. Methods: Acute oral toxicity of MP seed extract was assessed in albino rats with three different doses of the extract with 175, 550, and 2000 mg/ kg body weight. Body weight, mortality, and clinical signs were recorded on 0 (before administration), 7th, and 14th days. Rats were sacrificed after day 14 and observed for any histological changes in the brain, heart, liver, and kidney tissues. Rats were normal up to 1 h and exhibited dullness and piloerection after 1 h which continued up to 2–4 h of observation period on day 0 of administration. All animals appeared normal from day 1 to throughout the experimental procedure. Results: No significant changes in the histological structure of the liver, kidney, and heart were noticed except mild congestion and hydropic changes only in liver tissue seen for 2000 mg/kg body weight of HAMP seeds. The seed extract of MP is non-toxic to rats and did not show any mortality nor the behavioral changes. In addition, it showed an increase in the body weight with the administration up to 2000 mg/kg body weight. Conclusion: MP seed extract signified as neurosuppressant, and the drug can be used in the treatment of neurological disorders characterized by hyperactivity of the neurons. The present data could provide adequate confirmation of the safety of MP for further experimental studies on a standardized formulation of the seeds extract.
