This study therefore seeks to assess C. orchioides for its toxic effects by seeing body weight and organ weight changes and hematological and serum biochemical parameters and changes in histopathology. The root parts of C. orchioides were collected, shade-dried and then finely powdered (collected from the Bharathidasan University, Tamil Nadu). 500 g of powder was extracted with methanol using a Soxhlet apparatus. The solvent was then evaporated under reduced pressure at 40 °C and dried in vacuum dessicator. Adult albino

see more rats of the Wistar strain of either sex (170–190 g) were used in the present study and were obtained from Madras Veterinary College, TANUVAS, Chennai, India. The animals were housed

in clean polypropylene cages under conditions of controlled temperature (25 ± 2 °C) with a 12/12-h day–night cycle, they had free access to food and water ad libitum. Animal experimentation Ixazomib was carried out as per the rules and protocols approved by the Institutional Animal Ethical Committee (IAEC). The phytochemical tests were carried out on the methanolic extract of root parts of C. orchioides to determine the bioactive compounds using standard procedures. 5 The acute oral toxicity study was performed as per the Organisation for Economic and Cooperation and Development (OECD) 423 guidelines. Nine female rats were divided in to three groups (3 per group) i.e., control and two test groups. Control group received

0.5% carboxy methyl cellulose as vehicle at a dose of 10 ml/kg bwt while the test groups received an oral dose of 2000 mg/kg bwt of MECO (10 ml/kg bwt in 0.5% CMC). All the experimental animals were observed for their mortality and clinical signs of toxicity at 30 min, Phosphatidylinositol diacylglycerol-lyase 1, 2 and 4 h and thereafter once a day for 14 days following vehicle, MECO administration. Body weights were recorded once a week. On 15th day the overnight fasted rats (water allowed) were euthanized using CO2 euthanasia chamber and subjected to gross pathological examination of all the major internal organs such as brain, heart, lung, liver, kidney, spleen, adrenals and sex organs. LD50 cut-off value of MECO was determined in accordance with Globally Harmonized System of Classification and labeling of chemicals.6 In the present study, MECO was administered at three dose levels i.e., at 200, 400 and 800 mg/kg/day. Both sexes of Wistar Albino rats (170–190 g) were divided in to 4 groups with 10 animals (5 males + 5 females) in each. Group I served as control and received 0.5% CMC as vehicle orally at a dose of 10 ml/kg bwt. Remaining 3 groups received MECO at 200 (Group II), 400 (Group III) and 800 (Group IV) mg/kg/day, p.o, respectively (10 ml/kg bwt. in 0.5% CMC), for a period of 28 days. In order to determine the reversibility or recovery from toxic effects, additional satellite groups were preset (Group V & VI).
