Reasonable evidences suggest that heavy metal pollutants have been added by factories and other industries to our local water bodies. The present study was conducted to determine the heavy metal (zinc and lead) concentrations in muscle tissues of Labeo rohita inhabiting local water bodies as well as those being raised at farms. Sampling was performed to collect Labeo rohita from two different stations along river Ravi, viz. Lahore Siphon (upstream) and Balloki Headworks (downstream). Additionally, samples were also obtained from the government operated as well as private fish farms located in Lahore District, Pakistan. The fish were dissected; their muscles were digested, filtered, and finally analyzed for concentrations of Zn and Pb. Significant variation of heavy metal ions were observed between two sites along river Ravi as well as government operated and private fish farms. Significantly high mean concentrations of Zn (10.7±1.268) and Pb (0.61±0.082) were observed at Balloki Head-works; whereas, the lowest Zn (1.58±0.235) and Pb (0.16±0.008) heavy metal levels were recorded in the muscle samples collected from private fish farms. It was also observed that the heavy metal concentration in the muscles of Labeo rohita, collected from Balloki Head-works was much higher than the permissible limits laid down by WHO/FAO. Further the recorded highest level of heavy metals in water samples collected from River Ravi indicates that the bioaccumulation of heavy metals is severely affecting the aquatic life of fresh water and industries should not be allowed to release their effluent directly into the river Ravi in their vicinity.
Although, lipid lowering drugs regulate the blood serum lipids, they have several reported side effects. Therefore, a substance that is less toxic and yet effective would be beneficial. Here, we compared the antihypercholesterolemic effects of combinations of homeopathic mother tincture (HMT) Allium sativa Q (garlic) and Curcuma longa Q (turmeric), with standard lipid lowering drug statin. For experimentation, a total of 20 rabbits were recruited and divided into four groups with five rabbits (n = 5). Normal saline (NS) group served as control; second group served as high fat diet (HFD) group, third group received Allium sativa Q (garlic) and Curcuma longa Q (turmeric) and HFD (T and G group) while the fourth group received statin and HFD (statin group). At the end of the 8th week, blood was collected to analyze the comparative efficacy of Allium sativa Q, Curcuma longa Q and statin on total cholesterol (TC), low density lipoproteins (LDL), high density lipoproteins (HDL) and triglyceride (TG). Various parameters measured (mg/dl) in HFD rabbits were, TC (291.76±2.2), LDL (244.20±8.3) and triglycerides (243.79±4.3) increased significantly and HDL (32.19±3.3) was reduced to an alarming level as compared to the NS group after eight weeks. TC, LDL and triglycerides level reduced significantly in Tand G group while the HDL level increased significantly as compared to HFD. In statin group, TC (148.37±1.2), LDL (76.32 ±3.4) and TG (104.33 ±8.9) decreased while HDL increased (p LESS than 0.05) as compared to the HFD after eight weeks. It was therefore concluded that that homeopathic medicine Allium sativa Q and Curcuma longa Q is equally good like statin and can safely be used to regulate the circulating serum lipid profile
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
