Acute Toxicity Study

Piper guineense fruit is known for its nutritive and medicinal values. This study evaluated the biochemical effect of the methanol fruit extract of P. guineense on male albino rats. A total of thirty-eight (38) adult male Sprague-Dawley albino rats were used for the study. Eighteen of the male rats were used for the acute toxicity study, while twenty (20) male rats were randomly assigned into four groups (A, B, C and D) of 5 rats each, for the sub-acute toxicity study. Groups B, C and D were the treatment groups, while group A was the control group and received only distilled water (10 mg/ml). Groups B, C and D received 10 mg/kg, 200 mg/kg and 400 mg/kg body weight of the fruit extract respectively. Administration of the 100 mg/kg, 200 mg/kg and 400 mg/kg of methanol fruit extract of P. guineense led to a significant (P < 0.05) increase in the serum ALT and AP on day 7 of the experiment. Throughout the experimental period, 200 mg/kg of the extract caused a significant (P < 0.05) increase in serum total proteins and globulin. Group D rats had significantly (P < 0.05) lower serum total cholesterol on day 28 of the experiment. The 100 mg/kg of the extract caused a significant increase in serum urea and creatinine on day 21 of the experiment. Oral administration of methanol fruit extract of P. guineense caused mild hepatocellular injury, hyperproteinemia, hyperglobulinemia, hypocholesterolemia, and mild renal toxicity.

Acute Toxicity Study

Background. Withania frutescens. L (W. frutescens) is a perennial woody medicinal plant belonging to family Solanaceae largely used by the indigenous population to Morocco for the treatment of disease. Objective. The purpose of this study was to investigate the chemical composition, acute, and subacute toxicity of W. frutescens extract in mice. Materials and Methods. The phytochemical composition of W. frutescens extract was determined using a gas chromatograph (GC/MS). Acute toxicity study was carried out in mice through oral administration of single doses 500 mg/kg, 1000 mg/kg, and 2000 mg/kg for 14 days. Subacute toxicity was performed with oral administration of repeated doses 500 and 2000 mg/kg/day for 28 days. Biochemical parameters (alanine aminotransferase, aspartate aminotransferase, urea, and creatinine), as well as histopathological changes potentially occurred in organs, (liver, kidney, and spleen) were evaluated. Results. The results of chromatographic analysis showed the richness of W. frutescens extract in interesting phytochemical compounds majorly constituted of bicyclo[3.1.1]heptane, 6,6-dimethyl-2-methylene-(C10H16). Regarding acute toxicity study, the results showed no clinical symptoms occurred in treated mice compared to the control group and no histological changes detected in analyzed organs of treated mice with dose put to 2000 mg/kg nor adverse effect on biochemical parameters. Conclusion. The outcome of this work showed no toxic effect of W. frutescens in mice up to dose 2000 mg/kg bodyweight. Therefore, this study could scientifically validate further traditional use with safety in the range of tested doses.

Siddha system of medicine is the eternal science of life. It is a system that has its extensive bonding with Dravidian culture, language and beliefs. The system of medicine mostly prevailed and prospered in the regions of Dravidian cultures by the great Siddhars. It’s unique as one only than other AYUSH traditional systems of medicine across India with its distinctive abundant usage of medicinal plants, metals, minerals and animal products. Siddhars used the steps of Alchemy to prepare various medicines from metallic and mineral origin for attainment elixir and various rare diseases. Siddha medicine is classified into 32 types of internal and external medicine each. Among the 32 types of internal medicine Chendhuram is a medicine shelf life of 75 years usually from herbo-mineral combinations. Arumuga Chendhuram (ARC) is a herbo-mineral formulation cited in Siddha literature ‘Siddha Vaithiya Thirattu’. ARC was orally administered at higher dose 2gm/kg to the Wistar Albino rats in acute toxicity study and during 28 days of repeated (sub acute) toxicity study, at daily doses of 12, 24 & 48mg/kg of body weight to the Wistar Albino rats. Type II collagen arthritis is another model for developing autoimmune arthritis. The immune pathogenesis mediated by T cell and B cell response to collagen. By this model, nearly 100% arthritis can be achieved. In our study, ARC after 42 days treatment reduced the arthritic swelling significantly and degree of inflammation evident to act against auto immune disorder.

Acute Toxicity Study

Introduction: Ricinus communis is used by the people of Niger-Delta region of Nigeria, for the treatment of various ailments, especially malaria. This study evaluated the antiplasmodial potentials of the aqueous seed extract of R. communis, using Plasmodium berghei berghei. Methods: Acute toxicity study was carried out to determine the median lethal dose (LD50) of the extract. Antiplasmodial effect of the extract was assessed in suppressive, repository/ prophylactic and curative models, using Swiss albino mice (15-29 g). Mice were infected intraperitoneally with 0.2 mL of parasitized blood. Extract doses administered were 54.77, 109.54 and 164.32 mg/kg/d of the seed extract and each dose had 6 replicates. Artesunate (5 mg/kg/d) and pyrimethamine (1.2 mg/kg/d) were used as standard drugs, while distilled water (10 mL/kg/d) served as control. Results: Acute toxicity study produced LD50 of 547.72 mg/kg. The extract demonstrated a dosedependent reduction in parasitaemia in all tests. At the end of 4-day test, suppressive effect of 20.80, 49.00, 75.00 and 88.40% were obtained for doses 54.77, 109.54 and 164.32 mg/kg/d of the seed extract and artesunate, respectively. In the repository test pyrimethamine was more potent (72.26%) than the seed extract (9.47%–51.42%). The extract also exhibited appreciable curative effect. The activity of the seed extract was significant when compared with the control (P < 0.05). Mice treated with the seed extract and drugs survived for longer duration than the control group. Conclusion: The aqueous seed extract of R. communis has antiplasmodial potential and its active principle should be elucidated and further investigated to help in the ongoing fight against malaria.

Acute Study

Background: In Charaka Samhita it has been mentioned that three medicinal substances viz. Pippali (Piper longum), Kshara (alkali) and Lavana (salt) can be used as emergency medicine, but they should not be consumed in excess (Ati Upayunjita). If they are consumed in excess quantity they will cause several adverse effects in the body. Hence in the present study Kshara has been evaluated in experimental animals in two different phases viz. acute administration at graded doses as part of acute toxicity study and sub-acute administration at fixed dose level, as part of sub-acute toxicity study, to assess the possible adverse effects if any. Objectives: To evaluate the acute and sub-acute toxic effect of Kshara in albino rats to establish the principle of Trini Dravyani Nati Upayunjita. Materials and Methods: Wister strain albino rats of either sex weighing between 150 - 200g body weights were used for experimental study. The experiment was carried out as per ‘Ayush Guidelines’ after the IAEC clearance. For Acute Toxicity - 9 Albino rats were used and for Sub-Acute Toxicity - 12 Albino rats were used. The dose calculation was done on the basis of body surface area ratio using the table of ‘Paget and Barnes rule’. Results: In Acute toxicity study no mortality and behavioral changes were observed when the drug Kshara was studied after two dose level i.e. TED X 5 and TED X 10. In Sub-acute study some behavioral changes (including cage side behavior) were observed. No mortality was observed in any of the groups. Discussion: Acute toxicity study of Kshara showed no immediate and evident toxic signs and mortality within 24 hours of observation. In Sub-acute toxicity study in all four groups, no mortality or evident toxic effects were observed, however some mild histopathological changes were observed in sub-acute study.
