Acute Study

Background: Lavana is used as medicine as well as Ahara since ancient times. In Caraka Samhita it has been mentioned that three Dravyas viz. Pippali, Kshara (alkali) and Lavana (salt) can be used as emergency medicine, but they should not be consumed in excess (Ati Upayunjita). Hence in the present study Lavana 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 toxic Sub-Acute toxicity study, to assess the possible adverse effects. Materials andamp; Methods: Wistar strain albino rats of either sex weighing between 150 - 200g. body weights were used, The experiment was carried out in accordance with the direction of the Institutional animal ethics committee (IAEC) after obtaining its permission (Approval number IAEC – 138/k/2018). Results: Results were drawn based on histopathological reports and biochemical reports of each group of toxicity study. Acute toxicity study has been carried out in albino rats receiving the 2 dose level maximum at up to 10 times higher (855mg/kg) then the therapeutic equivalent dose (427.5mg/kg). In Sub-Chronic toxicity: dose given was five times higher than therapeutic equivalent dose and ten times the equivalent to human therapeutic dose for duration of 30 days. Discussion: Toxicity is not found in Acute study and in Sub-Acute study moderate to high toxicity is found.

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.

Mugdha Rasa is one type of Kharaliya Rasayana and comes under Nirgandha, Niragni Murchana of Parada. Parada and Khatika are the main ingredients of Mugdha Rasa. This investigation is an attempt to perform toxicological study of Mugdha Rasa. Acute toxicological study and sub-acute toxicological study were carried out as per OECD guideline 425 and 407 respectively. Oral acute toxicity study was carried out at the limit dose of 2000 mg/ kg orally in Swiss albino mice. Sub- acute toxicity study of Mugdha Rasa was carried out in Albino rats and it was administered at therapeutic equivalent dose (TED), TED ×2 and TED×5. No signs of toxicity and mortality were observed Mugdha Rasa in acute toxicity study. So, LD50 of Mugdha Rasa is greater than 2000 mg/kg body weight and Mugdha Rasa can be considered assafe on acute exposure. The data generated during sub-acute toxicity study are indicated that it is not a hazardous substance for sub-acute administration at TED dose level. Higher dose levels show mild changes in parameters.

Strobilanthes Crispus

BACKGROUND: Porang (Amorphophallus oncophyllus) is a local tuber food that high in bioactive compound glucomannan. It uses are limited due to oxalate acid content which poses health risks. Strobilanthes crispus leaves could reduce the level of calcium oxalate in porang. However, there is still no study to prove its safety. AIM: This study aimed to investigate the acute oral toxicity study of porang (A. oncophyllus) macerated with S. crispus based on observation of mortality rate (LD50), the changes in behavior during 72 h, renal and hepatic function such as urinary protein, serum glutamic oxaloacetic transaminase (SGOT), and serum glutamic pyruvic transaminase (SGPT) levels of Wistar rat (Rattus norvegicus) METHODS: An acute toxicity test was conducted based on the Organization of Economic Co-Operation and Development 420 Fixed-Dose Procedure Guideline that consists of preliminary and main studies. For the preliminary study, rats were divided into control and five treatment groups with the dosage of 50, 300, 2000, and 5000 mg/kg body weight (BW) for each natural porang flour (NPF) and S. crispus-macerated porang flour (SPF). For the main study, rats were divided into four groups, those were NPF and SPF with the dosage of 2000 and 5000 mg/kg BW. Levels of urinary protein and blood serum SGOT and SGPT levels were measured at 0, 24, and 72 after treatment. RESULTS: The acute toxicity study showed that porang and porang macerated with S. crispus were not toxic until the highest dose of 5000 mg/kg BW. It was proved by the absence of LD50, no change in behavior, no weight losses, and also the results of biochemical tests, such as urinary protein, SGOT, and SGPT which were still in the normal range. CONCLUSIONS: Porang flour and SPF were concluded as non-toxic food based on acute toxicity study.

BACKGROUND፡ The majority of population rely on traditional medicine as a source of healthcare. Artemisia afra is a plant traditionally used for its medicinal values, including treatment of malaria in many parts of the world. Currently, it is also attracting attention because of a claim that a related species, Artemisia annua, is a remedy for the COVD-19 pandemic. The aim of the present study was to investigate toxic effects of A. afra on brain, heart and suprarenal glands in mice aged 8-12 weeks and weighing 25-30g.METHODS: Leaves of A.afra were collected from Bale National Park, dried under shade, crushed into powder and soaked in distilled water to yield aqueous extract for oral administration. For acute toxicity study, seven treated and one control groups, with 3 female mice each, were used. They were given a single dose of 200mg/kg, 700mg/kg, 1200mg/kg, 2200mg/kg, 3200mg/kg, 4200mg/kg or 5000mg/kg b/wt of the extract. For the sub-acute toxicity study, two treated and one control groups, with 5 female and 5 male mice each, were used. They were daily treated with 600mg/kg or 1800mg/kg b/wt of extract.RESULTS: LD50 was found to be greater than 5000mg/kg indicating that the plant is relatively safe. In the sub-acute study, no signs of toxicity were observed in all treatment groups. On microscopic examination of the brain, heart and suprarenal glands no sign of cellular injury was observed.CONCLUSION: The findings of this study suggest that the leaves extract of A. afra is relatively safe in mice.

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.

Moringa oleifera (M. oleifera) Lam belongs to the family Moringaceae. It is an important multipurpose tree that is largely distributed globally and has been used almost in every aspect of traditional medicine for the treatment of various illnesses including cancers, diabetes mellitus, asthma, arthritis, etc. This study investigated the effects of oral acute and sub-acute administration of M. oleifera hydroethanolic leaf extract (MOHE) in ICR-mice. Its major phenolic compounds were also determined. Ten (10) female, 8-week old mice were grouped into control and treatment groups for acute toxicity study. A dose of 2000 mg/kg MOHE was given once to the treatment group via oral gavage. However, for the sub-acute toxicity study, 25 mice were grouped into groups A (control), B (125 mg/kg), C (250 mg/kg), D (500 mg/kg) and E (1000 mg/kg). MOHE was given via oral gavage to groups B, C, D and E daily for 28 days. Group A received only distilled water. The mice were sacrificed at the end of the experiments and samples were collected for evaluation. The results of the chemical profiling of MOHE revealed the presence of glucomoringin, niaziminine, quercetin and kaempferol as the major compounds. The treated mice in the acute toxicity study were slightly anaemic and showed evidence of stress leukogram. Moreover, a slight increase in creatinine, significant increases in AST and CK, hepatic degeneration and necrosis, none-obstructive sinusoidal dilatation, renal tubular necrosis, interstitial nephritis and renal interstitial oedema were observed. It is concluded that the LD50 of MOHE is higher than 2000 mg/kg. However, oral administration of MOHE causes acute mild anaemia and moderate hepato-nephrotoxicity in ICR-mice. Its major phenolic compounds are glucomoringin, niaziminine, quercetin and kaempferol.
