Abstract: A pot culture study has been undertaken to evaluate the effect of rolling and pickling industrial sludge amendments on growth response and bioaccumulation of heavy metal in wheat seedlings. Processed acidic waste was first treated with three doses of lime (0, 0.5 and 1%) and then mixed with two soils in different ratios (0, 10 and 20%). Samples were filled in earthen pots (2Kg/pot) one week before planting and seven days old wheat seedlings (3 per pot) were transplanted in these pots and pots were kept in glass house. Temperature of glass house was maintained at 2220C and moisture contained at 50% of water holding capacity. DTPA extractable heavy metals and metals in seedlings increased with increasing doses of industrial sludge amendments. Biomass and growth has been also found to increase with increasing rate of sludge. Lime enhanced the biomass and reduced the heavy metal concentrations. Although 20% treatments in both soils showed a significant enhancement in shoot length but metals like Pb was found beyond permissible limit. The heavy metal in wheat seedlings follow the trend Zn>Pb>Cu>Cd. Lime has a negative correlation with availability and uptake of heavy metals. Results showed that application of lime treated industrial sludge to soil could be useful in order to increase crop growth in the glass house. [Nature and Science 2010;8(3):1-8]. (ISSN: 1545-0740).

Abstract: Significant proportions of the landmasses of Ethiopia are covered by massive and continuous Rocky Mountains of different geological origin and composition, which can be useful even for organic farming. In the last decade, in fight against the recurrent drought in the north Ethiopian State of Tigray more than 46 dams have been constructed with a cumulative storage capacity and irrigable area of 49.91 million m3 and 3115 ha, respectively. However, in the irrigated fields of these dams, salt minerals like thenardite (Na2SO4), halite (NaCl), zincobloedite (Na2Zn(SO4)2.4H2O), and anorthoclase (Na,K)(Si3Al)O8 have been observed recently, which can cause sodicity thereby crop productivity can be impaired gradually. A list of management options should be tabled urgently before the problem is aggravated. Large gypsum deposit was found in the localities of the irrigated fields. Thus, this study attempted to evaluate the quality of these minerals whether they can be useful for agricultural purposes. Analysis revealed that up to 150 cm of the profile depth of the rock was mainly composed of gypsum (95%) with the predominance of oxides of S (43.5-46.6% SO3-2) and Ca (32.1-33.5% CaO). The oxides in the sampled rock followed the order of: SO3-2> CaO>SiO2>Al2O3>Fe2O3>MgO>Na2O>K2O>TiO2>MnO>P2O5 with the finest particle size (81.7-90%) dominating over other sizes. This study has come to the conclusion that Adigudom gypsum deposit can be used as rock for crops through enhancing sodicity management and sulphur nutrition. [Nature and Science 2010;8(3):9-14].

Abstract: Galeoides decadactylus (Bloch) is one of the three species of the family polynemidae commonly called the threadfins, found in warm tropical surface water of the Atlantic on the continental shelf of West Africa. They are important in the trawl fisheries of Nigeria. The specimens used for this study were collected off Nigerian coast from Lagos to Calabar between December, 2003 and November, 2004. In this study the length-frequency distribution, length - weight relationship, condition factor, sex ratio, fecundity, food and feeding habits of Galeoides decadactylus were examined. Measurements recorded for each fish were standard length (SL) and total length (TL) to the nearest 1mm and weight to the nearest 0.1g. Sexes of fish were determined by visual and microscopic examination of the gonads. Fecundity was estimated from the ripe ovaries (stage v) by the gravimetric method. The Gonadotropic Index (GI) and the Condition Factor (K) were calculated. Food items were quantified by two methods, the numerical and frequency of occurrence methods. The total length of 259 specimens examined ranged between 12.0cm and 28.3cm (standard length 9.9cm to 20.8cm). Specimens exhibited negative allometric growth. The condition factor increased with individual size. Females had a slightly higher condition factor than males. The sex ratio was 1:0.46 (male:female). The number of eggs per female ranged between 58 001 and 279 279. There was a negative correlation between log-fecundity and log-weight than between log-fecundity and log length. The major food items were crustaceans, molluscs, pisces and annelids. There were no distinctions in the feeding habits of the species in relation to size. The fish was euryphagus species and highly fecund. [Nature and Science 2010;8(3):15-23]. (ISSN: 1545-0740).

ABSTRACT: Reactive oxygen species and free radicals are involved in the nephrotoxicity induced by the synthetic anticancer drug cisplatin. The nephroprotective effects of carob pods and leaves (100 and 200 mg/kg, p.o.) was investigated using cisplatin (10 mg/kg body weight, i.p.) to induce oxidative renal damage in mice. The results showed that cisplatin administration caused abnormal renal functions in all studied mice. Serum urea and creatinine concentrations were significantly highered (P<0.5) in the cisplatin alone treated (control) group compared to the normal group. The concentrations of serum creatinine and urea in the carob pods (200 mg/kg body weight) treated group were reduced to 57.5% and 51.5%, respectively, with respect to the control group. Also, cisplatin induced decline of renal antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities, but the treatment of carob pods and leaves (100 and 200 mg/kg, p.o.) significantly attenuated the cisplatin-induced nephrotoxicity. Both pods and leaves of carob at 100 and 200 mg/kg increased the concentration of reduced glutathione (GSH) and protected against the increase of cisplatin-induced lipid peroxidation. In addition, treatment with cisplatin increased the activity of cathepsin D, RNase II, DNase II and acid phosphatase. The treatment of carob pods and leaves (100 and 200 mg/kg, p.o.) improved the activity of lysosomal enzymes nearly to the normal group. In conclusion, carob leaves and pods may be effective to protect from oxidative renal damage and the leaves are the better nephroprotective agent than pods. The protection may be mediated partially by preventing the decline of renal antioxidant statues. [Nature and Science 2010;8(3):41-47]. (ISSN: 1545-0740).

Abstract: Cultivated species of crops are usually variable because of artificial selection under diverse environments of which cowpea is not exception. Consequently, genotypic variability study was conducted with eight parent line cowpeas to evaluate some genetic parameters namely coefficient of variation, genetic variance and heritability estimates in the broad-sense. Per se mean performance was variable among the genotypes for all characters investigated which indicated the superiority of some parent lines. Highly significant heritability effects were observed for all characters except for 100-seed weight (42.2%) which expressed moderate heritability estimate. Days to 50% flowering, pod length, pod weight and grain yield characters showed that some levels of genetic variability existed. Consequently, progress could be made from selection and improvement for those characters. [Nature and Science 2010;8(3):48-55]. (ISSN: 1545-0740).

ABSTRACT: Under tropical soils, the precise requirement of inorganic fertilizer and its possible substitute is yet to be validated for the production of Amaranthus cruentus L. The nutrient requirement of A. cruentus under two soil types and yield quality under field conditions. Field experiment was conducted at two locations in Lagos State: Ikorodu (Orthic Luvisol) and Lagos State (LASU) Ojo Campus (Dystric Fluvisol) to investigate the effects of organic and organomineral and NPK fertilizer treatments on the quality of Amaranthus cruentus L. Eight fertilizer treatments. (1) Control (no fertilizer), (2) Pacesetter’s Grade B (PGB) 100 %, (3) PGB + NPK (75:25), (4) PGB + NKP (50:50), (5) Kola Pod Husk (KPH) 100 %, (6) KPH + NPK (75:25), (7) KPH + NPK (50:50) and (8) NPK (100 %) were tested at first planting. Residual effects of the fertilizers were assessed in the second and third planting periods. The experiment was arranged in a randomized complete block design in four Replications. Parameters assessed include proximate analysis. Data were analysed using ANOVA. The KPH + NPK (75:25)resulted in significant (p<0.05) higher crude protein content (19.8 and 14.9 %), ether extract (8.5 and 8.2 %) while crude fibre (9.5 and 10.8 %) was lower than control at Ikorodu and LASU respectively. The KPH and PGB had high potential in A. cruentus production. At Ikorodu, KPH + NPK (75:25) was the best while at LASU, PGB + NPK (75:25) was optimum. KPH + NPK (75:25) gave highest crude protein content, ether extract and lowest crude fibre in A. cruentus. [Nature and Science 2010;8(3):56-62]. (ISSN: 1545-0740).

Abstract: C.jejuni E.coli and S. typhimurium are the principal food borne pathogens in poultry industry. The first experiment tested the effectiveness of different strains of Lactobacillus as in vitro as probiotic against C. jejuni E.coli O157 and S. typhimurium Result showed that L.acidophilus isolated from colostrums of mare and goat showed the widest inhibition zone against C. jejuni E.coli O157 and S. typhimurium strains compared to the use of L.acidophilus isolated from goat and cattle milk. The second experiment evaluate the efficiency of L. acidophilus isolated from mare colostrums showing highest in vitro inhibition activity against tested strains as in vivo probiotic against C. jejuni isolated from broiler carcasses. The result showed great inhibition of C. jejuni E.coli O157 and S. typhimurium strains by the use of L.acidophilus in comparing to the use of antibiotics. In the second experiment; four groups of adult albino rats were used; group (1) control negative, group (2) rats orally administrated by L. acidophilus only from the start of experiment till the 14th day, group (3) rats challenged only with C. jejuni and group (4) orally administrated by L. acidophilus from the start of experiment till the 14th day at the 7th day they were challenged with C. jejuni. Result showed that the third group showed the highest rate of reisolation of C.jejuni (0.800.16 from fecal swabs and 0.840.17 from the internal organs) as well as major pathological lesions in the tested organs in the form of granulomatus reaction in the lung tissue infiltration of inflammatory cells in the lung tissue thickening of wall of blood vessels with alveolar emphysema. Congestion hemorrhages of renal blood capillaries and coagulative necrosis of the renal tissue as well as degeneration and necrosis of hepatocytes with proliferation of fibrous tissue. The forth group pretreated with L. acidophilus Showed lower rate of isolation of C.jejuni (0.080.02 from fecal swabs and 0.040.01 from internal organs. The pathological findings of the internal organs showed minor lesions in the form of interstitial pneumonia and inflammatory cellular infiltration in the lung Swelling and degeneration of renal epithelium and hepatocytic degeneration with infiltration of inflammatory cells. The second group which was only treated with L.acidophilus showed no reisolation of C.jejuni as well as no pathological lesions were detected except a minor lesion in the liver in the form of diffused vacuolar degeneration in hepatocytes. Results develop a safe method for competing food borne pathogens in edible animals and suggest the need for probiotics to hinder the spread of highly pathogenic zoonotic bacteria transmitted by animal food by products.

Abstract: The valley of Kashmir is famous for its marvellous landscape which attracts tourists from all along the globe. The landscaping of this heavenly abode predominantly involves alien ornamental plants. The present study puts on record the alien ornamental flora of Srinagar Kashmir, and thus, is a first compilation of alien ornamental flora of the region. The study enlists the occurrence of 271 exotic ornamental species distributed in 187 genera, belonging to 85 families, therefore piling up the total number of alien plant species in the Kashmir Himalayas to 704. The taxonomic composition analysis of alien ornamental flora of the region revealed that dicots are represented by 223 species (82%) belonging to 151 genera and 65 families while as monocots comprised of 39 species (15%) dispersed in 28 genera and 13 families. Gymnosperms are represented by 9 species (3%), 8 genera and 7 families. Asteraceae (11.07%), Rosaceae (9.59%), Oleaceae (4.79%) are the largest families of exotic ornamental plants introduced into the Kashmir Himalayas. Out of 85 families, 42 are represented by a single genus and single species. The highest number of alien ornamental species have come from the continent Asia (31%) followed by Europe (30%) and North America (20%). The study reports the occurrence of 133 alien ornamental species for the first time from Kashmir Himalayas. Our analysis of alien species establishment and invasion is not in consonance with Williamson’s tens rule and proposes that human assisted species selection, introduction and establishment change the entire dimensions of tens rule to maximum values in invasion biology.

Abstract: Model for predicting the concentration of dissolved iron (relative to the initial and final solution pH) during leaching of iron oxide ore in oxalic acid solution has been derived. The model;

γ2 – βγ - 0.001N = 0

%Fe

 

was found to calculate the concentration of dissolved iron being dependent on the values of the initial and final leaching solution pH measured during the leaching process. It was found that the validity of the model is rooted on the expressions D = 1000%Fe where both sides of each expression are correspondingly approximately almost equal. The maximum deviation of the model-predicted values of %Fe (dissolved) from the corresponding experimental values was found to be less than 28% which is quite within the acceptable range of deviation limit of experimental results. The value of the assumed coefficient of the dilution (N) was calculated to be 197.527. [Nature and Science 2010;8(3):104-109]. (ISSN: 1545-0740).

Abstract: Model for the calculation of the concentration of sulphur removed (during oxidation of iron oxide ore by powdered potassium chlorate) has been derived. The model was found to predict the concentration of sulphur removed, very close to the corresponding %S values obtained from the actual experimental process. It was found that the model is dependent on the values of the weight input of the oxidant (KClO3) during the desulphurization process. The validity of the model is believed to be rooted in the expression [(α)β%S] = T/γkn where both sides of the expression are approximately equal to 2. The positive or negative deviation of each of the model-predicted values of %S from those of the corresponding experimental values was found to be less than 30% which is quite within the range of acceptable deviation limit of experimental results.

Abstract: Introduction: Distinguishing between irritable bowel syndrome (IBS) and functional dyspepsia can be challenging because of the variations in symptom patterns, which commonly overlap. Although the principles of electrogastrography (EGG) have been known for years, it is contrvesial whether alteration of gastric electrical activity (GEA) could be of clinical relevance in functional gastrointestinal disorders.

Aim of the work was to assess the role of electrogastrography and gastric emptying in diagnosis of overlapping dyspepsia in patients with irritable bowel syndrome (IBS).

Subjects and methods: 120 patients with IBS were compared with 60 healthy controls. EGG was performed before and after a standard meal. Furthermore, gastric emptying (GE) and symptom scores were assessed.

Results: Of 120 IBS patients, 52 (43.3%) had dyspeptic symptoms as well as delayed gastric emptying. IBS patients with overlapping dyspepsia showed significantly more bradygastria (26.9%) than controls (5.9%) (P < 0.01) , also they had statistically significant lower PR compared to non dyspeptic patients(2.11.3 vs. 2.91.6 respectively P<0.05), moreover gastric emptying time was delayed in IBS patients with overlapping dyspepsia (14.71.8) compared to those without dyspeptic complaints and controls (10 1.27 & 10.62.1 respectively) (P<0.01).

Conclusion and recommendation: IBS patients with overlapping dyspepsia frequently reveal impaired gastric emptying and increased bradygastria, lack of a postprandial increase in the EGG amplitude, which may have pathophysiological significance in these patients .Using both EGG and gastric emptying test can aid in the detection of functional disorders associating IBS and therefore achieve greater patient satisfaction with their treatment.
