In the recent times wide use of agrochemicals in agricultural practice has caused severe health hazards to humans while their side effects have damaged the environment also. Endosulfan is an organochlorine insecticide effective against a wide range of pests of cereals, coffee, cotton, fruits, oilseeds, potato, tea and vegetables. Moreover, it is easily absorbed by the stomach, lungs and skin and exposure through any route can be hazardous. In the present study, Endosulfan was administered orally at the dose of 3mg/Kg body weight to Swiss albino mice for 4 weeks. Upon 4 weeks Endosulfan pretreated mice group, Emblica officinalis (Amla fruit) at the dose of 100 mg/Kg b.w was orally administered for 4 weeks to these groups to observe the ameliorative effect. Mice were sacrificed at each interval and their blood were collected for biochemical assay especially lipid profile. The lipid profile study showed inclination in the total cholesterol level, cholesterol (LDL) level and triglycerides level while declination in cholesterol (HDL) level after Endosulfan exposure. But upon Emblica officinalis (Amla) treatment to the endosulfan treated group showed significant declination in the total cholesterol level, cholesterol (LDL) level and triglycerides level while inclination in cholesterol (HDL) level. Thus, from the above study it can be concluded that although the entrance of these hazardous pesticide (Endosulfan) into our body cannot be stopped but by the use of these medicinal plant extracts as potent antidote can solve the problem at much extent, normalizing the physiology of the body and maintaining the cellular integrity and normal functioning of the system.

Pests are responsible for the loss of one third of worlds agriculture production every year. In India approximately, agricultural products of more than 60 billion annually are destroyed by pests. Every year this problem is increased by the appearance of new pests and diseases [1]. Pesticides are group of chemicals mainly designed for the destruction of pests but besides killing pests it also affects the heath of non-target organisms. only a small percentage (0.3%) of applied pesticides goes into the target pest while 99.7% go somewhere else into the environment [2]. Endosulfan is an organochlorine insecticide effective against a wide range of pests of cereals, coffee, cotton, fruits, oilseeds, potato, tea and vegetables. Moreover, it is easily absorbed by the stomach, lungs and skin and exposure through any route can be hazardous. Commercially produced endosulfan consists of two isomers α endosulfan and β endosulfan. Both these forms have been proved to be genotoxic to human gonads [3,4]. 

Due to the high persistence and bioaccumulation potential, the Stockholm Convention has classified endosulfan as environmental hazards and banned the use of many of them. Pesticide safety is classified by the World Health Organization (WHO) according to the results of LD50 tests, which document the amount of a chemical required to kill 50% of a population of laboratory animals. Under this system, endosulfan is currently classified as Class II – moderately hazardous to human health.  However, the United States’ Environmental Protection Agency (EPA) rates endosulfan as Category Ib - highly hazardous. LD50 data for endosulfan are equivocal, with some published results indicating that the chemical should be in the WHO’s Class Ib, according to the organization’s own criteria [5]. Evidence of the threats to human health posed by endosulfan is abundant, and the chemical has been banned outright or severely restricted in a number of countries as a result. Independent of LD50 results, these threats warrant the immediate upgrading of endosulfan to WHO Class I b [6]. 

Emblica officinalis (Amla) also known as Indian gooseberry is perhaps the most important medicinal plant in the Indian traditional system of medicine [7,8]. Amla is a source of phenolic compounds, which include phenolic acids and flavonoids [9]. Apart from vitamin C, amla also contains cytokine like substances such as zeatin. The dried Amla fruit is useful in the treatment of hemorrhage, diarrhea, dysentery and is the best antioxidant known in India [10].  Hence, the present work aims to study the ameliorative effect against Endosulfan induced toxicity in Swiss albino mice.


Ethical approval 

Ethical approval was taken from Post Graduate Research Council (PGRC) of Patna University, Patna with no. PGRC No. Acad - / 464, serial No. 7, dated 12/02/2007. 


Twenty four Swiss albino mice (28g to 32 g) were obtained from animal laboratory of Dr. A. Nath, Department of Zoology, Patna University and Patna, India. The research work was approved by the Post Graduate Research Council of the Patna University.  Food and water to mice were provided ad libitum (prepared mixed formulated feed by the laboratory itself). Animals were maintained in colony rooms with 12 hrs light/dark cycle at 22 ± 2°C. 


The commonly used pesticide- endosulfan was obtained (Excel India Pvt. Ltd. Mumbai with EC 35%). The pesticide was prepared to 3 mg/Kg b.w, which was administered orally to mice for 4 weeks. Commercially available kit for chemical analyses like Serum Cholesterol, HDL, LDL Cholesterols and Triglyceride were used of crest coral clinical system, Goa, India. 

Plant material 

The fresh dried fruit form of Amla purchased from herbal store in Patna and identified by Dr. V Pandit, Department of Botany, Patna Science College, Patna University Patna, India and aqueous extract was made by dissolving it in distilled water using by mortal and pistal. The dose was finally made to 100 mg/kg body weight for oral administration. 

Experimental design 

In the present study 24 mice (18 Endosulfan treated and 6 as control mice) were taken and divided into groups - control, Endosulfan treated and Amla treated. The endosulfan at the rate of 3mg /kg body weight daily was administered orally for 4 weeks. To this endosulfan treated group amla at the rate of 100mg / kg body weight was administered for 4 weeks. After the completion of the experiment blood samples were collected by orbital sinus puncture method and then serum was extracted. 

Statistical analysis

Results are presented as mean ± S.D and total variation present in a set of data was analyzed through one-way analysis of variance (ANOVA). Difference among means has been analyzed by applying Dunnet’s ‘t’ test at 99.9% (p< 0.001) confidence level. Calculations were performed with the GraphPad Prism Program (GraphPad Software, Inc., San Diego, USA).


The lipid profile tests total cholesterol levels, LDL cholesterol levels and triglycerides levels show inclination in the levels while HDL cholesterol decreased levels in the Endosulfan treated group in comparison to control group was observed. But, after E.officinalis treatment total cholesterol levels, LDL cholesterol levels and triglycerides levels shows decreased in the levels while there was significant increase in the HDL cholesterol levels denotes the ameliorative effects (Figures 1-4).

Lipids are one of the important sources of energy, carriers of fat-soluble vitamins, components of bile salts and precursors for the synthesis of steroid hormones. Lipids are mainly synthesized in liver. Biochemical characteristics of blood are the important indicator of status of internal environment of an organism. Most of the pesticides act as metabolic depressors and generally affect the activity of biologically active molecules such as proteins, carbohydrates and lipids [11]. A number of studies have been carried out regarding the biochemical alterations in blood induced by pesticides in general [12-18]. 

In the present study, the hyperlipidaemia in mice exposed to endosulfan can reasonably explained on the basis of hypothesis that endosulfan induces oxidative stress in the cells especially in hepatocytes.  Liver is the main site of detoxification so it requires more energy for detoxification. To meet additional energy demands liver cells starts biosynthesizing of different classes of lipids. This leads to the elevation in total cholesterol, LDL cholesterol, and triglyceride level in blood serum of endosulfan induced mice. Hence, it can be speculated that inclination in lipid profile is one of the compensatory mechanism of mice to adopt to pesticides like endosulfan. The inclination in serum lipid content resulting in hyperlipidaemia is certainly due to stress induced by pesticide poisoning for longer periods. The test animals in the present study were observed to be restless throughout the exposure period. They were in constant fast movements aided by muscular action.  Lots of extra energy was required to minimize the stress induced by endosulfan. The observed hyperlipidaemia during present investigation may be also due to impairment in the membrane organization and damage to liver. In a similar study, [19] have reported that increased level of serum cholesterol in Oreochromis niloticus exposed to phenol may be due to impairment in the membrane organization induced by the acclimatization in acidic water or water contaminated with phenol in order to get the positive survival value under the imposed stress. Endosulfan, are also known to induce oxidative tissue damage resulting from the release of ROS [20] and free radicals play an important role in the pathogenesis of inflammation [20-23]. Endosulfan also acts as a xenoestrogen binding with the lipid membranes and causing severe damage to them due to lipid peroxidation. The lipid peroxidation in turn causes depletion of lipid from the membranes making the blood lipid rich, more viscous and enhancing the chance cardiovascular disease. Thus, there are multiple possible pathways that might lead to selective alteration in rates of synthesis or metabolism of some classes of serum lipids. Lipid profile abnormalities play a significant role in atherosclerosis and cardiovascular disease. The findings of the present investigation indicate that exposure to endosulfan alters the metabolism of cholesterol and thus increases the risk of cardiovascular disease and atherosclerosis. 

But, the medicinal plants have potent ameliorative effect in controlling the hyperlipidaemic effect. The high levels of vitamin C and fiber in amla are thought to be responsible for its cholesterol-lowering effects. Amla reduced levels of triglycerides (TG) TG in the blood. High TG level of in the blood are linked to low levels of High-Density Lipoprotein-Cholesterol (HDL-C) The vitamin C in amla accounts for 45-70% of its antioxidant activity. Reactive Oxygen and Nitrogen Species (ROS and RNS) cause inflammation. The phenolic compounds in amla decreases both ROS and RNS. Amla reduces oxidative stress in DNA and prevents liver cells from dying (necrosis) [24]. In the present study also there was significant amelioration in the lipid profile levels denotes that Amla indeed possesses anti-hyperlipidaemic property. The phenolic compounds of E.officinalis may serve as potential medicinal plant for amelioration of acute and chronic inflammation due to their modulatory action of free radicals [25]. The pharmacological studies have also shown that amla fruit was able to lower the lipid level in the liver of rodents [26]. Other studies also reveal that free phenolic contents of E.officinalis were three times more than that of bound form. Both phenolic fractions of E.officinalis are consisting of gallic and tannic acid. Phenolic fractions are also known to possess various secondary metabolites, such as flavonoids and phenolic acids, etc., that are well known to possess highest antioxidant activity [27-32]. Hence, the present study reveals that Emblica officinalis possesses ameliorating property against endosulfan induced toxicity.


Endosulfan causes deleterious effect on the lipid profile functions in the Swiss albino mice, but after the treatment of Emblica officinalis there was significant control in the lipid profile levels. Thus, Emblica officinalis possesses anti-hyperlipidaemic activity normalizing the physiology of the body and maintaining the cellular integrity and normal functioning of the system.
