Abstract: The study was designed to evaluate the level of knowledge of Nigerian Veterinary Laboratory Staff on the nature of Highly Pathogenic Avian Influenza (HPAI) disease using structured questionnaires. The study comprised the Staff of National Veterinary Research Institute (NVRI) and five reference Veterinary Teaching Hospitals (VTH) designated for HPAI diagnosis. A total of 69 questionnaires were distributed to the laboratory staff. Questions on the general nature of the disease such as the cause, signs, mode of transmission, methods of identification, lesions, control and prevention, etc. were asked. The results showed that 77.38% of the staff answered all the questions correctly indicating their considerable knowledge of the HPAI disease. Considerable percentage of the staff listed correctly the equipment used for serology (36.23%) and RT-PCR (31.88%). Interestingly only 13.04% of the staff listed correctly the equipment used in rapid tests despite the fact that they are simpler and recommended for all P2 laboratories. In conclusion, the veterinary laboratory staff assessed demonstrated a significant level of knowledge on HPAI diagnosis; however, most of their laboratories lack the structure, organization, funds and basic facilities required for effective HPAI diagnosis.

Nigerian Journal of Basic and Applied Sciences , 2009,
Abstract: The in vitro trypanocidal activity of aqueous extracts of some selected medicinal plants used by local herdsmen in the treatment of various animal diseases in Sokoto State, Nigeria was conducted. Trypanosoma brucei brucei were cultured using 96 well micro titer plate and maintained at 370C. About 20 – 25 parasites per microscope field were dosed with 1, 2 and 4mg/ml of aqueous extracts of the plants and a control group without extracts. After 5 minutes incubation in Eppendorf tubes maintained at 370C, the parasites survived more than four (4) hours in the absence of extract/Berenil. At 4mg/ml of the extracts 0f Terminalia catappa, Waltheria indica, Cucurbita pepo, Entada abyssinica and Ximenia Americana, complete cessation of motility of T. brucei brucei within 60 minutes was observed. However, at 2mg/ml of Waltheria indica, trypanosome motility after 20 minutes was stopped but Terminalia catappa, and Ximenia americana were found to reduce trypanosome motility at 35 and 55 minutes respectively. Only Waltheria indica reduced trypanosome motility within 25 minutes at 1mg/ml concentration. Berenil, the standard drug, caused cessation of trypanosomal motility within 60 minutes even at 1mg/ml. From the results Waltheria indica was the most effective among the extracts when compared with Berenil, and may be a potential source of compounds with trypanocidal activity.

Control of Meloidogyne incognita (kofoid and white) chitwood (root-knot nematode) of Lycopersicon esculentus (tomato) using cowdung and urine
U Abubakar, T Adamu, SB Manga
African Journal of Biotechnology , 2004,
Abstract: Screenhouse experiments were conducted to test the efficacy of cowdung and urine separately and in combination in the control of root-knot nematode of tomato. Equal quantities of cowdung, urine and their mixture were separately made up to one litre with autoclaved soil. Two weeks old seedlings of tomato raised in autoclaved soil were transplanted into soil manure mixture and inoculated with 1,000 second stage larvae of Meloidogyne incognita race I. Treatments were completely randomized and effects assessed based on plant height, dry weight, extent of galling and the nematode multiplication factor. Results obtained showed that cowdung, urine, and their mixture produced significantly higher result than the untreated control. Similarly, the mixture of urine and cowdung, produced significantly higher results than the separate treatments.

Abstract: Antenatal clinics perform routine serological tests for syphilis as a screening procedure. Syphilis is still a serious but treatable disease with maternal and fetal complications. There are two categories of serological tests for syphilis, the cardiolopin; venereal disease research laboratory (VDRL) test and the specific tests treponema Pallidum haemagglutination (TPHA) test. Pregnancy is a recognised cause of false-positive VDRL test result. The aim of the study was todetermine the seroprevalence and cost-effectiveness of antenatal syphilis screening at Aminu Kano Teaching Hospital (AKTH), Kano, Nigeria. The method includes a retrospective analysis of venereal disease research laboratory (VDRL) test results among pregnant women in AKTH during a 4 year period (January 2007-December 2010) was undertaken. The resulst include: a) fourteen –thousand, eight hundred and seventy-one pregnant women were screened for syphilis, using VDRL test; 95women were positive. Only eighty- two (82) folders were retrieved and analyzed given a seroprevalence rate of 0.55%.The peak age specific incidence was in the 20-24 years age group, b) the median gestational age at booking was 22 weeks, c) the cost of VDRL testper patient in AKTH is $2.5. To detect the 95 seropositive cases the sum of $38,106 was spent. It was concluded that the seroprevalence rate of syphilis in this study was low (0.55%). Initial screening using VDRL alone is neither justified nor cost effective. Selective screening base on risk factors and confirmatory test with FTA-AB is recommended.

Advances in Breast Cancer Research (ABCR) , 2014, DOI: 10.4236/abcr.2014.31001

BACKGROUND: Papillary carcinoma of the breast is a rare malignant tumour accounting for 1% - 2% of all breast cancers in women. Papillary carcinomas of the chest wall are always secondary to thyroid, thymus and ovaries. Other variants of breast cancer metastasizing to the chest wall have been reported. CASE: We report a 67-year-old woman presented to us with an ulcerated anterior chest wall mass of 1-year duration, bilateral axillary, supraclavicular and cervical swellings of 8-month duration. There was a history of breast lump which was noticed 5 years prior to presentation, no history of breast malignancy in the past and no family history of breast cancer. Examination revealed an ulcerated, nodular mass over the sternal angle which measured 14 cm × 12 cm

SM Jodi, T Adamu, U Abubakar, MG Abubakar, S Adamu, VE Ukato
Sokoto Journal of Veterinary Sciences , 2008,
Abstract: Phytochemical study on the crude extract of the roots Gardenia sokotensis revealed the presence of alkaloids, glycosides, saponins and steroids and very little or no tannin, and flavonoid, content. The acute toxicity study carried out revealed complete absence of any clinical or beahavioural changes that could be suggestive of toxicity in any of the animals in groups A, B and C following treatment with the crude extract of the roots of the plant. However, depression, weakness and loss of appetite as evidences of toxicity in the first 5hrs were observed in groups D and E animals that were treated with higher doses of the extract. All the animals (Groups D and E) treated with the higher doses of the crude extract of the roots of the plant eventually died 40 – 96 hours post-administration. The LD50 of the Gardenia sokotensis root extract was found to be 2400mg/kg body weight when orally administered in rabbits.

Bayero Journal of Pure and Applied Sciences , 2011,
Abstract: Dried leaf powder of Cybopogon citratus was extracted with distilled water, acetone and hexane using percolation method. The extracts were screened for the presence of alkaloids, flavonoids, reducing sugars, tannins and saponins using standard procedures. Inhibitory activities of the extracts were tested against clinical isolates of Escherichia coli, Salmonella spp., Klebsiella spp. and Proteus spp. using disc diffusion method and broth dilution techniques. The results of phytochemical screening have demonstrated the presence of alkaloids, flavonoids, reducing sugars, tannins and saponins in some or all of the extracts. Similarly, the results of antibacterial activity testing of the extracts at equal disc concentration of 30@g/disc showed that E. coli was sensitive to all extracts with inhibition zone diameters of 7mm, Klebsiella spp. and Proteus spp. were sensitive to acetone extract of the plant with inhibition zone diameters of 7mm each while Salmonella spp. was sensitive to acetone and hexane extracts of the plant with inhibition zone diameters of 7mm and 8mm respectively. Salmonella spp. demonstrated MIC and MBC values of 1000@g/ml and 2000@g/ml respectively. These results suggest that C. citratus used in this study has the potential for the production of drugs against bacterial infections.

Nigerian Journal of Surgical Research , 2005,
Abstract: Objectve: To analyse all nephrectomies performed by general surgeons at Usmanu Danfodiyo University Teaching Hospital, Sokoto (UDUTH) over a ten-year period. The setting provided an opportunity to critically examine the process and outcome of nephrectomies done by general surgeons. Method: A retrospectively study of nephrectomies performed by general surgeons in UDUTH in the 10 year period (January 1993 to December 2002). Results: A total of 25 nephrectomies were performed by the general surgeons during the study period. The male to female ratio was 4:1. The indications were renal malignancy in 39.0% of cases others were non-functioning symptomatic hydronephrotic kidneys. Renal function was not assessed in two patients with renal trauma before surgery. In some patients with polycystic renal disease and pelvic- ureteric junction obstruction indication for nephrectomy was not properly described. The disease staging and extent of surgery in patients with kidney cancer were not often stated. In 20% of patients there was significant morbidity and a threat to life and the overall mortality was 13.0%. Conclusion: In the dearth of the urological surgeons in our environment the had to supplement in the occasional care of some urological patients. The best result is outcome is from patients having nephrectomy for non functioning hydronephrotic kidneys. The outcome in the treatment of the congenital renal anomalies, malignant and trauma to the kidney was not satisfactory suggesting the trained urologist will be better equipped to sort things out.
