The comparative analysis of the proximate compositions of Tarpon atlanticus (megalops) and Clariasgariepinus (African catfish) collected from two culture systems (Pen and concrete pond) were examined . Parameters of proximate composition analysed were moisture, ash, protein, fibre, fat and carbohydrate from the head and tail region. Proximate composition comparison was also done with various sizes of the two species of fish which are the juvenile, young adult and a dult forms . The total length and weight of juvenile ranged from 24.5 - 26.5cm, 178.3 - 180g and 25.2 - 27.4cm, 177.6 - 179.5g for T. atlanticus and C. gariepinus , respectively. For the young adult, the total length and weight ranged from 27.0 - 28.5cm, 212 .0 - 220.1g and 26.9 - 29.4cm, 214.2 - 221.3g for T. atlanticus and C. gariepinus , respectively. For the adults, the total length and weight ranged from 40.20 - 42.10cm, 783 - 800g and 39.9 - 44.5cm, 785 - 805g for T. atlanticus and C. gariepinus , respectively . Analysis of variance (ANOVA) showed no significant difference (P<0.05) between the moisture content of T. atlanticus and C. gariepinus in the adult head although there was a significant difference (P<0.01) between the ash of T. atlanticus and C. gariepinus in the adult tail. There was no significant difference (P<0.05) between the protein of T. atlanticus and C. gariepinus in the young adult tail but there was a significant difference (p<0.05) between the fibre of T. atlanticus and C. gariepinus in the juve nile tail. There was a significant difference (p<0.01) between the fat and oil of T. atlanticus and C. gariepinus . Ash content was highest in the adult head of T. atlanticus and lowest in the adult tail of C. gariepinus . Protein was at its highest in the young adult tail of C. gariepinus and lowest in the juvenile head of T. atlanticus . The low concentration of lipids in the muscles of these species could be due to poor storage mechanism s and the use of fat reserves during spawning activities. Generally the two species contain high protein content as f ou nd out in this study. The high tissue protein content may have resulted from high protein content of their diets. Thus , both fish species constitute a high source of protein and low fatty acids, as well as an ideal dietetic fish food for human consumption.

This study was carried out to determine and compare the proximate composition and length weight relationship of C. gariepinus from two culture systems (earthen and concrete ponds). The fish samples were collected from three fish farms with same cultural condition in different areas of Obio-akpor Local Government Area of Rivers State, Nigeria. Result on the length- weight relationship revealed that C.gariepinus reared in concrete tank had a total length of 15.50- 49.00cm with a mean of 32.71cm and weight of 150-625g, while total length of C. gariepinus reared in the earthen pond ranged from 19.90-58.0cm with a mean of 39.8cm and weight of 195-825g. The T- test shows that the total length of earthen pond were significantly higher than the concrete tank and the weight in the earthen pond was significantly higher than the concrete tank. Parameters of proximate composition analysed were moisture, protein, lipid, carbohydrate, ash and fiber from the fish flesh. Protein content showed a significantly higher in the earthen ponds than the concrete tanks. Ash contents varied from 1.5±1.66-7.4±0.67% in the concrete tanks and were significantly higher than the earthen ponds which ranged from 3.1±0.94-4.5±2.11%. Lipid was significantly higher in earthen ponds than concrete tanks. Generally, the two culture systems have a significant influence on length–weight relationship and nutritional value of C. gariepinus. However, C. gariepinus reared in concrete tank had a heavier body weight than earthen pond and also C. gariepinus reared in earthen pond had highest nutritive values than the concrete tank.

Cytotoxicity Endpoints

Cell culture systems have become increasingly popular as a means of screening toxic agents and studying toxic mechanisms of drugs and other chemicals at the cellular and subcellular levels. These in vitro tests can be conducted rapidly in a broad range of relevant mammalian culture systems; a variety of biological and biochemical cytotoxicity endpoints can be examined. The following study utilized human keratinocytes to evaluate the relative cytotoxicities of nitrofurazone (NF) and silver sulfadiazine (SS), the active ingredients of FURACIN(R) Topical Cream and SILVADENE(R) Cream, respectively. These compounds are anti-infectives used in the treatment of burn patients. Cell ultrastructure and elemental composition were utilized as cytotoxicity endpoints.Normal Human Epidermal Keratinocytes (HK) were prepared from the EpiPackTM culture system (Clonetics Corporation, Boulder, CO). For scanning electron microscopy (SEM) and transmission electron microscopy (TEM), cells were seeded on sterile 35 mm Falcon plastic dishes; for elemental microanalysis, cells were plated on polished pyrolytic carbon discs (E. Fullam, Latham, NY) placed in the culture dishes.
