Milk thistle seed oil (MTSO) has been subjected to extensive research. The fixed oil was extracted from the seeds of Silybum marianum (L.) using petroleum ether as a solvent by a soxhlet device. GC-MS was used to identify the chemical composition of the oil. The antioxidant activity of MTSO was tested by the ABTS method, which showed the ability to inhibit lipid peroxidation. In addition, antimicrobial and antifungal investigations were examined. It proved that MTSO has an inhibitory effect against Gram-positive bacteria (Staphylococcus aureus), Gram-negative bacteria (Escherichia coli), and antifungal effects (Candida albicans). MTSO has a slightly higher effectiveness against fungi than bacteria. Moreover, the cytotoxic activities of the oil on hepatocellular and colorectal carcinoma were examined. MTSO has shown a moderate cytotoxic effect on the HCT-116 cell line and a weak effect on HePG-2. Whereas;in vivo study has been done on five diagnosed patients who have impaired liver function, and were recruited for the study. Their weight ranged from 100 ± 30 kg, their age range was between 39 - 50 years. Each patient was given ten drops of MTSO daily and added to a little water for a four-week study period. MTSO has effects to improve the function of the injured liver. The present work aims to study Milk thistle seed oil, for estimating its pharmacological properties for the liver. This study focused on showing the importance of milk thistle seed oil in our lives as a source of antioxidants, anti-bacterial and anti-fungal, and as an anti-cancer of the liver and colon. It also sheds light on its importance as a treatment for impaired liver, function and fatty liver, due to its improvement in all liver function markers, so it can be hired as an effective human therapy.展开更多

Thus, it is crucial for detecting small infestations before they reach a significant extent that can cause ecological and economic damages over a large geological area. Remote sensing is a proven method for mapping invasion extent and pattern based on geospatial imagery and indicated great repeatability, large coverage area, and lower cost compared with traditional ground-based methods before. We investigated the feasibility and performances of adopting multispectral satellite imagery analyses for mapping infestation of musk thistle (Carduus nutans) on native grassland, crop field, and residential areas in early June using spectral angle mapper classifier. Our results showed an overall classification accuracy of 94.5%, indicating great potential of using moderate resolution multispectral satellite-based remote sensing techniques for musk thistle detection over a large spatial scale.展开更多

We studied how it can affect liver enzymes and hepatocytes in this group of patients. We took all these naturalplants and bee products in the optimal dose required by the body and prepared a paste called Herbal, so that everyday people couldeat comfortably as a food supplement, as well as see the therapeutic and prophylactic results. HERBAL paste for liver ingredients:flaxseed, ginger, seed of thistle, powder of yellow ginger, black cumin, and honey. Benefits: Herbal paste prepared based onwell-tested recipes improves the function of the liver and gallbladder. As a hepatoprotector, it affects the recovery of liver cells inliver diseases (hepatitis and cirrhosis), spleen disease, bile ductinfections, gallstones in gallbladders, inflammatory bowel disease,colitis, cholecystitis. It helps to remove toxic substances while taking medicine (antibiotics, chemotherapy, painkillers, etc.). Sideeffects: Individual sensitiveness to the contents of the product. Usage: In acute process 1 teaspoon, during chronic diseases 1dessertspoon twice a day before eating. Results: 48 women and 54 men with the third level of fatty liver dystrophy decreased to thesecond level (fibrosis did not occur). During the treatment of 114 patients who had an HCV (hepatitis C virus), I used HERBALpaste as a protector for the liver. After the analyses, 24 patients, who had liver cirrhosis ALT (alanine aminotransferase) and AST(aspartate aminotransferase) in the blood reduced twice. Another 81 patients from 90 who had virus had disappeared in bloodanalyses and in the exogenous factor of liver and GGT in the blood get normal.展开更多

In this way, recently, our study group reported the efficacy of the Mediterranean diet associated to an antioxidant complex, to improve in overweight patientsnot only anthropometric parameters, but also insulinresistance, lipid serum levels, and intra-hepatic fat accumulation.展开更多
