The growth and development of human body is dependent on the protein, carbohydrate, vitamins and minerals. Fishes are one of the major sources of protein, vitamins and minerals for human. This study was conducted to know the effect of Mystus gulio fish fillet on growth performance of albino rats after feeding different concentrations of fish fillet as a protein source with formulated cereal for 32 days. Haematological and histopathological analysis were performed between control group and examined groups of albino rats. It was noticed that the body weight of each experimental albino rat was increasing gradually with increasing fish fillet up to 15% and beyond this the value was decreased. Moreover, the highest protein efficiency ratio (PER) and calorie efficiency ratio (CER) were observed 2.53% and 13.02% respectively for 15% supplied fish fillet. The gained in body weight (GBW) of albino rats in each experimental group depended mainly on supplied fish protein concentration but not on formulated cereal. According to hematological and histopathological studies, no toxicological effect was observed between control group and experimental groups of rats treated with different fish protein concentration for 32 consecutive days. Supplement of 15% fish fillet with formulated cereal was required to produce maximum nutritive values and the Mystus gulio could be considered as protein rich human diet. تفاصيل المقالة

Adsorption is a very promising and interesting technique for removal of heavy metal ions. In this study orange peel and waste tea leaves were used as low cost adsorbents for removal of iron (III) ion from wastewater. Batch adsorption studies were employed to investigate the influence of pH, time, doges and initial metal ion concentration. The maximum removal capacity of orange peel and waste tea leaves were observed at pH 9 for iron (III) removal. For both adsorbents 75 min was required in order to achieve equilibrium for the adsorption of Fe (III) ion. The influence of adsorbent dose was checked by using different dosage of adsorbents. Adsorption parameters were investigated by using Langmuir and Freundlich isotherm. The removal of Fe (III) ion by using both adsorbents moderately fit the Langmuir and Freundlich isotherm. From the result it was observed that the adsorption capacity of waste tea leaves is higher than orange peel. تفاصيل المقالة
