Rheumatoid arthritis (RA) is an inflammatory disease with autoimmune origin that affect joints firstly and then progress to be a systemic disease. Toll like receptor (TLR) play an important role in the evolution and progression of this disease. Captopril is an angiotensin

enzyme inhibitor (ACEI) that is widely used to control elevation in the blood pressure. This drug has anti-inflammatory activities, for this reason we try to investigate its action in RA. In this study we found that captopril decreases both expression and intensity of TLR2.

Hepatocellular proliferation is one of the most common causes of hepatocellular carcinoma (HCC), a type of cancer that is widely distributed disease. Hepatocellular carcinoma treatment has numerous barriers, including ineffectiveness, side effects, and drug resistance to currently available

treatments. Previous studies showed that a high intake of Brassica vegetables has been associated to a decreased risk of a number of malignancies. The aim of this study is the evaluation of antiproliferative activity of Brassica nigra seeds extract in mice exposed to phenobarbital. Brassica nigra seeds where extracted; phytochemical analysis of the extract was done that including phytochemical screening tests and Gas chromatography-mass spectrometry (GC-MS) analysis. Antiproliferative activity of hydro alcoholic Brassica seeds extract has been studied by 800mg/kg and compare with control group (given normal saline), phenobarbital group (Phenobarbital 75mg/kg) and combination group (Brassica extract 800mg/kg+ Phenobarbital 75mg/kg). The GC-MS analysis revealed the presence of isothiocynate compound. Histologically phenobarbital induced severe hepatocellular proliferation (hyperplasia and hypertrophy), glass ground cytoplasm, while Brassica seeds extract produce improvement in histopathological changes that include mild scattered proliferation picture and eosinophilic cytoplasm. In comparison to phenobarbital group, Combination groups pretreated with Brassica nigra seeds for 14 days and phenobarbital for 7 days caused significant reduction relative liver weight and alanine aminotransferase (ALT) Brassica nigra seeds extract have isothiocynate as main compound it showed antiproliferative action on the liver tissue, implying that it may have a promising effect in minimizing the risk of liver cancer.

Isatin is a heterocyclic molecule that belongs to one of the most important classes of organic compounds known as indolines. Isatin, isatin analogs, and their Schiff bases have recently attracted a lot of attention in medicinal chemistry. Isatin, itself, shows various biological activities such as antiviral, anticancer, antimicrobial, anti-inflammatory, analgesic, antioxidant, and anticonvulsant. Bis- Schiff bases containing isatin moiety have been known to possess a wide spectrum of pharmacological activities. This review offers up-to-date information on the most active isatin bis-Schiff bases, which would include anticancer, antimicrobial, antiviral, anticonvulsant, anti-inflammatory, and analgesic activities. These observations can lead to new molecular modifications that result in compounds with more desirable pharmacological properties

Acute kidney injury (AKI), formly known as acute renal failure (ARF), is an abrupt and reversible decrease in kidney function as indicated by the glomerular filtration rate (GFR). Diclofenac-induced AKI is due to toxic effect of it on renal glomeruli, resulting in glomerular lesions.

Furthermore, diclofenac causes autolysis, which increase renal intracellular osmolarity that leads to proximal renal tubular dilatations. Lipoic acid (LA) has antioxidant and anti-inflammatory activities. Bosentan is a competitive endothelin A (ETA) and endothelin B (ETB) receptors antagonist. In this study, the evaluation of effectiveness of lipoic acid and bosentan against diclofenac-induced AKI was done by histopathological examination. The results showed that diclofenac caused histopathological changes include; retracted glomerulus, tubular cast, tubule-interstitial inflammation and tubular necrosis. Lipoic acid or bosentan alone could not reduce the histopathological alterations caused by diclofenac. Meanwhile, the combination therapy was able to reduce the histopathological changes significantly (p>0.05). Therefore, the combination therapy of lipoic acid and bosentan showed promising ameliorative effect against diclofenac-induced AKI
