This study was to investigate the variations of heavy metals in Liza abu from the Musa estuary which receives petrochemical wastes. Fish samples were obtained from five different creeks. The samples were dissected into liver, gill and muscle, acid digested and their heavy metals level were analyzed. The results showed that the concentration of Cd, Co, Cu, Ni and Pb in muscle ranged 0.08-0.44, ND-1.63, 0.89 - 4.28, 0.48 - 2.73 and 0.5 - 2.50 (μg/g) respectively. Their concentrations in liver were 0.44 - 2.03, 0.5 - 2.80, 5.05 - 36.22, 0.48 - 4.91 and 0.66 - 5.74 (μg/g) respectively. The concentration of these metals in gill was 0.32 - 2.72, 0.29 - 1.10, 4.33 - 6.03, 4.61 - 17.52 and 2.64 - 21.41 (μg/g) respectively. Generally, the level of heavy metals in muscle tissue of Liza abu was lower than the general standard.展开更多

METHODS: Databases including PubMed, Scopus, Google Scholar, and Web of Science were searched for studies focusing on the ethnomedicinal use, phytochemical compounds and biological and pharmacological activities of parsley. Data were collected from 1966 to 2013. The search terms were: "Parsley" or "Petroselinum crispum" or "Petroseli-num hortence ". RESULTS: Parsley has been used as carminative, gastro tonic, diuretic, antiseptic of urinary tract, anti-urolithiasis, anti-dote and anti-inflammatory and for the treatment of amenorrhea, dysmenorrhea, gastrointestinal disorder, hypertension, cardiac disease, urinary disease, otitis, sniffle, diabetes and also various dermal disease in traditional and folklore medicines. Phenolic compounds and flavonoids particularly apigenin, apiin and 6"-Acetylapiin; essential oil mainly myristicin and apiol; and also coumarins are the active compounds identified in Petroselinum crispum. Wide range of pharmacological activity including antioxidant, hepatoprotective, brain protective, anti-diabetic, analgesic, spasmolytic, immunosuppressant, anti-platelet, gastroprotective, cytoprotective, laxative, estrogenic, diuretic, hypotensive, antibacterial and antifungal activities have been exhibited for this plant in modern medicine. CONCLUSION: It is expectant that this study resulted in improvement the tendencies toward Petroselinum crispum as a useful and important medicinal plant with wide range of proven medicinal activity.展开更多
