| 15 | Cyclophosphamide Induced-Thrombocytopenia | Cyclophosphamide Injection 1 g | Cyclophosphamide is an alkylating agent that forms cross-linkages in DNA. These cross-linkages can damage or kill cells, including megakaryocytes. Megakaryocytes are the cells that produce platelets. When megakaryocytes are damaged or killed, they produce fewer platelets. This leads to thrombocytopenia, a condition in which the number of platelets in the blood is too low. | NO-Standard Drug | Rat, Sprague Dawley | Hematology -Analyser | Body weight: Twice a week,Complete blood count (On day 0 and days 3, 7, 11, and 15 post-cyclophosphamide injections), Blood serum for estimation of oxidative stress parameters.,Histopathological Analysis of femur and spleen (H&E),Cytological examination of bone marrow smear. |
| 16 | Folic Acid-Induced Acute Renal Failure | Folic Acid (250 mg/kg, IP) | Folic acid is a water-soluble vitamin that is essential for DNA synthesis and cell growth. In high doses, folic acid can cause oxidative stress and mitochondrial damage. Oxidative stress is a condition in which there is an imbalance between the production of free radicals and the body's ability to detoxify them. Mitochondrial damage is damage to the mitochondria, which are the power plants of the cell. When oxidative stress and mitochondrial damage occur in the kidneys, it can lead to acute renal failure. | Ibudilast | Rat, Albino Wistar | Biochemistry Analyzer, Metabolic Cage | Body weight: Twice a week, Kidney weights, Serum biochemistry parameters: Blood Urea Nitrogen, Creatinine, Sodium, and Potassium., Urinary biochemistry parameters: Creatinine and Urine Urea Nitrogen, N-acetyl-ß-D glucosaminidase, and Kidney Injury Marker-1., Gene expression analysis by Real-Time PCR: Nfr2, NQO-1, HO-1, IL-1β, TNF-α, NF-κB, iNOS., Histological analysis of kidneys (Hematoxylin & Eosin-stained). |
