Isolation and indentification of fungi associated with date fruits (Phoenix dactylifera, Linn) sold at Bayero University, Kano, Nigeria
S Ibrahim, MA Rahma
Bayero Journal of Pure and Applied Sciences , 2009,
Abstract: Mycological investigation on spoilage fungi in 30 apparently infected date fruits (Phoenix dactylifera, Linn.), sampled from both new and old campuses of Bayero University, Kano, Nigeria was carried out between August and September 2008. The samples were cut into 3 mm pieces on a clean and sterilized tile with the aid of sterilized razor blade, surface-sterilized in 1% hypochlorite for 2 minutes, placed on Potato Dextrose Agar and incubated at room temperature for 5 days. Pure cultures of the resulting fungi were obtained from subcultures of the primary plates. These were identified morphologically and microscopically in accordance with standard procedures. The investigation showed that the most dominant isolated fungi were Rhizopus sp. (100%) and Mucor sp. (100%), followed by Torula sp. (40%),Penicillium sp. (30%), Aspergillus sp. (16.67%) and Alternaria sp. (13.33%) respectively. Of all the samples, soft dates were the most heavily contaminated probably owing to the artificial increase in moisture content and improper storage facilities associated with it. Aspergillus species appeared to be the most toxigenic fungi recovered from the dates. It was recommended that soft dates should be stored in a cold environment while dry dates should be stored under dry condition so that they will not increase in moisture and avoid constant exposure to air at sales time, hence the use of paper wraps should be encouraged. Similarly, contaminated dates should be sorted and eliminated to avoid re-infection while washing the dates with clean water prior to consumption should be strongly encouraged by appropriate authorities with the view to checking the spread of these fungi.
Reclosure Efficiency of Plastic Container Used for Multidose Packaging of Moisture Sensitive Aspirin Tablets.
MA Ibrahim, IJ Inyagi
Tropical Journal of Pharmaceutical Research , 2002,
Abstract: This study was conducted to determine the suitability of packaging aspirin tablets in one thousand tablet packs that require reclosure after dispensing each dose. The reclosure efficiency of the push-fit type closure of a plastic container in preventing moisture entry was determined and compared to a control container. Aspirin tablets used in this study were shown to be susceptible to moisture degradation leading to significant losses of potency (p = 0.005). Loose placement of closure on container allowed significant gain of moisture into the container (p = 0.05) and this could lead to significant loss of potency of aspirin tablets. However, if the closure is properly pushed down to fit, the moisture gain is not significant (p = 0.05). It can, therefore, be concluded that the proper use of push-fit closures on containers for packaging aspirin tablets provides effective protection and the use of more expensive single unit strip packaging, for example, is therefore not necessary.
In vivo activity of stem bark aqueous extract of Khaya senegalensis against Trypanosoma brucei
MA Ibrahim, GC Njoku, AB Sallau
African Journal of Biotechnology , 2008,
Abstract: Aqueous extract of Khaya senegalensis A. Juss (Meliaceae) stem bark was used to treat trypanosomiasis in rats in vivo and changes in levels of aspartate transaminase (AST) and alanine transaminase (ALT) were studied. The treatment involved oral infusion of the crude extract at 60 mg/kg body weight (b.w) simultaneously with Trypanosoma brucei infection, and 60 and 100 mg/kg b.w infusion of the extract 3 days post infection (p.i). In all the rats treated with the extract, a significant decrease (P < 0.05) in parasitemia was recorded on day 6 p.i and there was also significant (P < 0.05) increase in the levels of AST and ALT when compared with rats that were neither infected nor given the infusion of the extract. It was concluded that orally infused K. senegalensis extract possessed in vivo activity against T. brucei but could not prevent the disease-induced liver damage.
Perceptions of Hospital Pharmacist’s Role in Pakistan’s Healthcare System: A Cross-Sectional Survey
S Azhar, MA Hassali, MMI Ibrahim
Tropical Journal of Pharmaceutical Research , 2011,
Abstract: Purpose: To investigate hospital pharmacists’ perception of their current clinical role in Pakistan’s healthcare system. Methods: This was a cross-sectional study in a population that consisted of hospital pharmacists in Islamabad, Faisalabad and Lahore which are three cities in Punjab State, Pakistan. A sample of 116 hospital pharmacists was selected from public and private hospitals in these three cities. Results: At least 42.2 % of the hospital pharmacists were involved in patient education pertaining to drugs. Although they were willing to take personal responsibility for resolving drug-related problems encountered, 84.5 % of them conveyed that their current role is more focused on pharmacy record keeping. Only 57.8% of the pharmacist indicated that they were involved in compiling and updating of their hospital’s drug formulary. Conclusion: The findings suggest that hospital pharmacists in Pakistan do have concerns about their present professional roles and face significant barriers with regards to increasing their involvement in clinical services. However, they need to be proactive in their collaboration with other healthcare professionals if the concept of pharmaceutical care is to take root in the healthcare system.

Abstract: The aim of this research was to investigate conduct disorder among pupils of primary schools in Khartoum, the capital of Sudan. School survey descriptive method was used and 384 pupils were selected from primary schools through systematic sampling technique. Age ranged from 5 to 17 years old with a mean of (9.34) years. The tools of data collection consisted of the Sutter-Eyberg Student Behavior Inventory. The statis-tical tests used to analyze the collected data involve frequency and percentage, Pearson co-efficient of correlation, mean, t-test for one sample and t-test for two independent samples. The results of this research revealed that that the prevalence of conduct disorder among pupils of primary schools in Khartoum was low. There were significant differences in conduct disorder between male and females pupils. There were no significant differences between pupils of pre-paratory classes and pupils of elementary classes. There was no significant correlation between conduct disorder and age.

Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.37107
Abstract: Difference equations or discrete dynamical systems is diverse field whose impact almost every branch of pure and ap- plied mathematics. Every dynamical system an+1=f(an) determines a difference equation and vise versa. We ob-tain in this paper the solution and periodicity of the following difference equation. xn+1=(xnxn-2xn-4)/(xn-1xn-3xn-5, (1) n=0,1,... where the initial conditions x-5,x-4,x-3,x-2,x-1 and x0 are arbitrary real numbers with x-1,x-3 and x-5 not equal to be zero. On the other hand, we will study the local stability of the solutions of Equation (1). Moreover, we give graphically the behavior of some numerical examples for this difference equation with some initial conditions.

AB Aliyu, H Ibrahim, AM Musa, MA Ibrahim, AO Oyewale, JO Amupitan
African Journal of Biotechnology , 2010,
Abstract: Anisopus mannii (Asclepiadaceae) –a plant widely used as an anti-diabetic agent in Northern Nigerian traditional medicine, was subjected to antioxidant evaluation. The crude methanol extract, n-butanol and ethyl acetate fractions were investigated for free radical scavenging activity of the 1, 1-diphenyl-2- picrylhydrazyl radical (DPPH), total phenolic contents and reducing power assay. The results of the DPPH free radical scavenging at 250 ìgml-1 indicated maximum antioxidant activity of 94.1, 94.3 and 88.7% for crude methanol extract, ethyl acetate and n-butanol fractions, respectively. The total phenolic content was higher in the ethyl acetate fraction (59.60 mg/g gallic acid equivalent GAE) than in the nbutanol fraction (56.40 mg/g GAE) and crude methanol extract (53.20 mg/g GAE). The reducing power of n-butanol fraction was 0.112 nm higher than those of ethyl acetate fraction (0.110 nm) and crude methanol extract (0.106 nm). The antioxidant activities of the crude extract/fractions and the standards at maximum concentration of 250 ìgml-1 decreased in the order: ascorbic acid> ethyl acetate fraction> crude methanol extract> Gallic acid> n-butanol fraction, but there was no significant difference (p < 0.05) between them. The phytochemical screening revealed the presence of flavonoids, tannins and saponins. This suggests a potential utility of the plant as a source of phenolic antioxidants and may provide leads in the ongoing search for natural antioxidants from Nigerian medicinal plants to be used in treating diseases related to free radical reactions.

Bayero Journal of Pure and Applied Sciences , 2009,
Abstract: Bauhinia rufescens Lam (Leguminosea-Caesalpinoideae) stem bark was extracted using methanol and fractionated using ethylacetate, butanol and water. The extract and fractions were subjected to preliminary phytochemical screening using standard procedures followed by antimicrobial screening using disc diffusion and broth dilution techniques. The extract and fractions showed the presence of carbohydrate, tannins, flavonoids, saponins, terpenes and steroids. The antimicrobial screening of the extract and fractions against clinical isolates of Staphylococcus aureus, Streptococcus pyogenes, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli and Candida albicans, using disc diffusion method at disc potency of 100μg/disc showed inhibitory activity on the test isolates with zone of inhibition ranging from 16-37mm. The methanolic and ethylacetate extracts showed the least MIC of 1.25mg/mL. The result of the study confirms the traditional use of the stem bark of B. rufescens in the treatment of infections caused by susceptible microorganisms.

African Journal of Biotechnology , 2009,
Abstract: This study was performed to determine the effects of fermented seeds of Carica papaya on litters of female Wistar rats, and ascertain its safety as a food condiment. Animals in group one served as control, and were given only water; those in groups two and three were given the aqueous extract of the fermented seeds of C. papaya at 500 and 1500 mg/kg, respectively, from gestation day six to gestation day 15, kept till terms and allowed to litter. Results showed that the percentage increase in weight of rats in the control group was not significant (P<0.05) when compared to those administered the fermented extract at 500 and 1500 mg/kg. There was no significant difference (P<0.05) in litter size and litter body weight in rats within all the groups, compared to the control group. Also, the anogenital distance (AGD) to crown rump length (CRL) ratio in rats dosed with the fermented extract of C. papaya seeds at 500 and 1500 mg/kg was not significantly different from the control group. In conclusion, this study has shown that the fermented seeds of C. papaya seeds does not affect the litters and may be safe as a food condiment.
