Background: Liver injury induced by drugs has become a primary reason for acute liver disease and therefore posed a potential regulatory and clinical challenge over the past few decades and has gained much attention. It also remains the most common cause of failure of drugs during clinical trials. In 50% of all acute liver failure cases, drug-induced hepatoxicity is the primary factor and 5% of all hospital admissions. Methods: The various hepatotoxins used to induce hepatotoxicity in experimental animals include paracetamol, CCl4, isoniazid, thioacetamide, erythromycin, diclofenac, alcohol, etc. Among the various models used to induce hepatotoxicity in rats, every hepatotoxin causes toxicity by different mechanisms. Results: The drug-induced hepatotoxicity caused by paracetamol accounts for 39% of the cases and 13% hepatotoxicity is triggered by other hepatotoxic inducing agents. Conclusion: Research carried out and the published papers revealed that hepatotoxins such as paracetamol and carbon- tetrachloride are widely used for experimental induction of hepatotoxicity in rats.

Alzheimer's disease (AD) is a chronic neurodegenerative brain disorder characterized by memory impairment, dementia, and oxidative stress in elderly people. Currently, only a few drugs are available in the market with various adverse effects. Therefore, to develop new drugs with protective action against the disease, research is turning to the identification of plant products as a remedy. Natural compounds with anti-inflammatory activity could be good candidates for developing effective therapeutic strategies. Phytochemicals, including Curcumin, Resveratrol, Quercetin, Huperzine-A, Rosmarinic acid, genistein, obovatol, and Oxyresvertarol, were reported molecules for the treatment of AD. Several alkaloids, such as galantamine, oridonin, glaucocalyxin B, tetrandrine, berberine and anatabine, have been shown anti-inflammatory effects in AD models in vitro as well as in-vivo. In conclusion, natural products from plants represent interesting candidates for the treatment of AD. This review highlights the potential of specific compounds from natural products along with their synthetic derivatives to counteract AD in the CNS.

Background: Great Mullein; Verbascum thapsus has been traditionally used as an analgesic, anti-inflammatory, antiseptic, spasmolytic, astringent, diuretic, emollient, expectorant piles, bruises and frostbites in Greece, Western United States, Rome, India, Turkey, Italy, and Pakistan.Objective: The aim of the present review is to summarize ethnopharmacology and past/recent studies on phytochemistry, plant profile, botany and pharmacological profile of V. thapsus. The review also updates related information regarding the potential therapeutic targets and new metabolites isolated from V. thapsus.Methods: All the information was supplied by the library database and electronic search (Google Scholar, ScienceDirect, PubMed, ResearchGate, etc.). In addition, all the synonyms of V. thapsus were searched in Non-English journals and English/Non-English- MS and PhD thesis databases (e.g., CKNI-China, JAIRO-Japan, Shodhganga-India, Myto-Malaysia, etc.). Thorough literature survey on V. thapsus revealed compounds like glycosides, flavonoids, saponins, and terpenoids that have previously been reported and new compounds under these chemical classes and other classes have also been reported.Conclusion: Based on the literature survey, many of these isolated compounds or different extracts of V. thapsus possess a wide range of biological activity including but not limited to, antioxidant, wound-healing, antimicrobial, antiviral, anticancer, cytotoxic, antihyperlipidemic, anti-germination, hepatoprotective and nephroprotective activity.

Background: Traditionally, Portulaca oleracea Linn. is used for treating abscesses, dysentery and liver diseases. In addition, recent studies have reported its efficacy as an analgesic, as neuroprotective, anti-inflammatory, bronchodilatory, and anticancer agent, besides antioxidant, wound healing and other important pharmacological actions. Aim and Objective: For curing liver diseases, Chinese use juice from the fresh leaves of Portulaca oleracea Linn. Hence, to prove this claim, an in-vivo hepatoprotective study of extracts from Portulaca oleracea Linn. against carbon tetrachloride hepatotoxic rats was carried out. Methods: The in-vitro antioxidant activity by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and hepatoprotective activity of extracts of Portulaca oleracea Linn. was assessed against the carbon tetrachloride-induced toxicity rat model. Results: The extracts of Portulaca oleracea Linn produced concentration-dependent percentage inhibition of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and most significantly, by methanol extract. Among the extracts, methanol extract showed a significant decrease in Serum glutamic oxaloacetic transaminase (SGOT), Serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase (ALP) levels and a significant increase in total protein (TP) levels against carbon tetrachloride-induced liver toxicity Conclusion: From the results obtained, it was concluded that methanol extract of Portulaca oleracea Linn. possesses significant DPPH free radical scavenging and hepatoprotective potential.

Purpose: To study the adverse drug reactions (ADR’s) reported from Dermatology ward in SMHS hospital of Srinagar. The adverse drug reactions were analyzed by Naranjo’s causality assessment scale and the outcomes were studied. Methods: This observational and cross-sectional study was conducted for one month of July 2018 in an inpatient setting of Dermatology ward of SMHS hospital. The data collection was done only in Dermatology ward. Patients of all age groups and either sex were included in this study. The adverse drug reactions were assessed for their causality by performing the Naranjo’s algorithm scale. The outcomes were studied. Result: Total 3 adverse drug reactions were reported from Dermatology ward. 20-40 years age group was studied for adverse drug reactions. The most commonly affected organ is the Skin 2 (66.66%), followed by Reproductive system 1 (33.34%).The 3 reported ADR’s were Acute Urticaria in 2 patients and Azoospermia in 1 patient. According to Naranjo’s algorithm scale, out of 3 suspected ADR’s 2 (Azoospermia: Cyclophosphamide and Acute Urticaria: Sulfasalazine) were probable and 1 suspected ADR (Acute Urticaria: Tetanus Toxoid) was possible. Out of 3 patients, 2 with Acute Urticaria recovered while as patient with Azoospermia continued with the problem during study. Limitations: Study was conducted only in one ward i.e., Dermatology and patient number was also less.
