Carvacrol hinders the progression of hepatic fibrosis via targeting autotaxin and thioredoxin in thioacetamide-induced liver fibrosis in rat.

Fibrosis is a common outcome of nearly all chronic diseases of liver that results in changes of its functions which requires medical attention. The current research aims to investigate the potential anti-fibrotic efficacy of Carvacrol against thioacetamide (TAA)-induced liver fibrosis in male rats using Ursodeoxycholic acid (UDCA) as a reference anti-fibrotic product. Carvacrol (25 and 50 mg/kg) markedly declined TAA-increased serum liver enzymes; alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) as well as total bilirubin (TB) and direct bilirubin (DB) levels as well as increased levels of total protein (TP) and albumin. Carvacrol significantly reduced glutathione depletion (GSH), Nitric oxide (NOX) and malondialdehyde (MDA) accumulation in liver tissue. Additionally, its anti-oxidant effect brightened up via affecting markers of stress found in the cell as nuclear factor erythroid 2-related factor 2 (Nrf-2) where it still had high content and decreased Thioredoxin (Trx) level. The anti-inflammatory effect of Carvacrol was confirmed by decreasing nuclear factor kappa B (NF-κB), interleukin-1beta (IL-1ß) and inducible nitric oxide synthase (iNOS) contents. Carvacrol showed anti-fibrotic effect clarified by turning down fibrosis-related markers; TGF-ß1, matrix metalloproteinase-3 and 9 (MMP-3 and 9) and Autotaxin (ATX) contents. Furthermore, it decreased alpha smooth muscle actin (α-SMA) and caspase-3 immune-expression. The overall outcome of aforementioned markers results showed that Carvacrol suppresses the progression of liver fibrosis via its anti-oxidant, anti-inflammatory, anti-apoptotic effect and its ability in lowering Thioredoxin and Autotaxin; hence it can be categorized as a hepatoprotective natural substance.

Synthesis and evaluation of 2,6-piperidinedione derivatives as potentially novel compounds with analgesic and other CNS activities.

New 2,6-piperidinediones 2(a-g) and 4(a-d) were prepared by initial condensation of aromatic aldehydes or cycloalkanones with cyanoacetamide to give alpha-cyanocinnamides l(a-g) or cycloalkylidenes 3(a,b) which underwent Michae1 addition with ethyl cyanoacetate or diethylmalonate. Compounds 4(a-d) were alkylated by various alkyl halides to produce the N-alkylated 2,6-piperidinedione derivatives 5(a-m). Some new selected compounds 2(a-c,f), 4(a-d) and 5(e,h,j) were pharmacologically evaluated for potential anticonvulsant, sedative and analgesic activities. These compounds exhibited significant anticonvulsant and analgesic effects after a single I.P. administration 100 mg/kg b.wt. On the other hand all the investigated compounds induced hypnotic activity and prolonged the phenobarbital sodium- induced sleep as compared with the control group and the most potent compound was found to be 2(f).

[Ritual circumcision. A medicosocial problem]. / Rituel cirkumcision. Et medikosocialt problem.

Circumcision is one of the oldest and most common operations, which has been practised for thousands of years by Moslems, Jews and various tribes in Africa, America, and Australia. Unfortunately, complications may occur during and after circumcision, ranging from trivial to tragic. Our investigation shows a higher incidence of complications when performed by a non-qualified surgeon. We therefore recommend that the operation should only be done by a surgeon in the public health service.
