ABSTRACT

The prevalence of Sexually Transmitted Infections (STIs) among female students of Abia State University Uturu (ABSU) was studied. Blood samples and High Vaginal Swab (HVS) samples were collected from four hundred and fifty (450) female undergraduate students and investigated for various agents of STIs including: Candida albicans, Neisseria gonorrhoea, Treponema pallidum, Staphylococcus aureus and Human Immuno Deficiency Virus, using standard microbiological methods. The HVS were analyzed using direct wet smear and culture techniques while blood samples were examined using standard proprietory agents. Out of the 450 female students sampled, Candida albicans had the highest prevalence rate of infection of 39.55%. It was followed by S. aureus (24.22%) and T. pallidum (4.0%). N. gonorrhoea and HIV was not isolated among the female students. There was a significant difference in the prevalence level of infection with age (x² cal 7.2616 P<0.05 df3), faculty based distribution (x² cal 3.887 P<0.05 df4). Increased screening for STIs is essential in preventing disease transmission and complicated health problems among these groups.

ABSTRACT

Microcytic-hypochromic anaemia was induced in Clarias gariepinus (Burchell, 1822) at intervals of 1, 14 and 28 days.  Experimental fish were exposed to test water separately diluted with sub lethal concentrations of sniper 1000EC of 0, 0.27, 0.31, 0.41 and 0.55mg/L. A 28 days exposure to sublethal concentrations of the toxicant resulted in changes in heamatological parameters of the fish on the exposure days (1, 14 and 28). Blood dyscrasias attributable to microcytic- hypochromic anaemia  was observed with a significant (p<0.05) decrease in haemoglobin, haematocrit, red blood cells, white blood cells, lymphocytes, monocytes, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC). Neutrophils, eosinophil and basophil increased significantly (p<0.05) with increasing concentrations of the toxicant.

ABSTRACT

The effect of methanolic extract of Cyperus esculentus L. on follicle stimulating hormone, luteinizing hormone, testosterone and some sperm parameters in twenty four  adult albino male wistar rats. After six weeks administration of extract of Cyperus esculentus L., results showed statistically significant difference in LH levels at P < 0.05 between Group A (4.80 ± 1.04) compared with experimental Group B (5.70 ± 0.46), Group C (5.48 ± 0.27) and Group D (5.45 ± 0.37). FSH levels showed statistically significant difference at P < 0.05 between Group A (11.55 ± 0.46) compared Group D (15.20 ± 1.33). There was no statistically significant difference at P > 0.05 between Group A (11.55 ± 0.46) compared with Group B (11.30 ± 1.93) and Group C (11.08 ± 0.78). Testosterone levels showed statistically significant differences at P < 0.05 between Group A (3.30 ± 0.30) compared to Group B (3.75 ± 0.47), Group C (4.23 ± 0.34) and Group D (3.63 ± 0.63). The sperm count levels showed statistically significant differences at P < 0.05 between Group A (168.0 ± 4.54) compared to Group B (182 ± 4.94), Group C (174.25 ± 6.86) and Group D (176.0 ± 6.09). There was statistically significant difference at P < 0.05 between Group A (71.50 ± 1.55) compared to Group B (74.25 ± 1.54) and (76.25 ± 2.59). However, there was no statistically significant difference at P > 0.05 between Group A (71.50 ± 1.55) compared with Group C (68.50 ± 3.75). Results showed that methanolic extract of Cyperus esculentus significantly increased gonadotropins, testosterone and sperm parameters in a dose-dependent fashion.

ABSTRACT

Blood samples from four (4) groups (A, B, C and D) of albino rats of four rats per group were analyzed for Alanine Aminotransferase (ALT) and Alkaline Phosphatase (ALP) secretions. The analysis was carried out in two phases; phase 1 and phase 2. In phase one, which was the zero analysis, the weights of the animals were taken and the blood samples were collected and analysed. From the analysis, it was observed that there were secretions of ALT and ALP in the albino rats before administration. In the second phase of the analysis, the groups A, B, and C were orally administered 500 mg/kg, 250 mg/kg and 125 mg/kg of P. grisea respectively while the control (group D) were administered tragacant solution which was the vehicle used. After three weeks of administration, the blood samples were collected for final analysis to check the effect of P. greasia on both ALT and ALP secretions. It was however observed that there was significant decrease (P>0.05) in ALT and ALP secretions except in group D that served as the control. This could therefore be deduced that P. grisea may have a hepato-protective ability if properly utilized.

ABSTRACT

Cockroaches are found to be associated with human dwellings worldwide thereby; affecting public health through their habits which makes them ideal mechanical carriers of several pathogens such as bacteria, viruses, helminths, protozoa and fungi. This study was conducted to isolate and identify bacteria from external surfaces and digestive tract of 50 Cockroaches collected around human dwellings in Jere Local Government Area of Borno State, Nigeria. Colonial morphology and biochemical characterization revealed that cockroaches harboured Escherichia coli, Proteus mirabilis, Bacillus subtilis, Klebsiella pneumoniae, Corynebacterium pyogenes, Staphylococcus aureus, Staphylococcus epidermis, Streptococcus faecalis, Salmonella typhi and Pseudomonas aerugenosa, on their cuticle and intestinal contents. Antimicrobial sensitivity tests were indicated by diameter of inhibition zone in millimetres. Complete resistance was observed with floxapen, ampicillin and erythromycin for Gram positive isolates, and ampicillin and ampicillin/cloxacilin for Gram negative isolates. However, pockets of resistance were observed for cephalexin, cotrimoxazole, amoxicilin, clindamycin and ofloxacin for Gram positive bacteria, and tetracycline, norfloxacin, amoxicillin, ofloxacin, chloramphenicol, cefuroxime and gentamicin for Gram negative bacteria. In conclusion, cockroaches in Maiduguri harbour pathogenic bacteria which showed resistance to antimicrobial agents.

ABSTRACT

A survey was conducted to determine the comparative studies between Gallus-gallus domesticus and exotic breeds of chickens and prevalence of coccidiosis in Benisheikh Town, Borno State. A total of 211 chickens were examined in four wards of Benisheikh town. Sixty (60) chickens were examined from North (Lawanti ward), 70 chickens from South (Ajari ward), 37 chickens from West (Mallamti ward), 44 chickens from East (Kasula ward) respectively. 211 chickens surveyed consists of 106 (50.2%) were Gallus-gallus domesticus and 105 (49.8%) were exotic breeds. 122 (57.8%) were between 12 and 36 months (Adults) while 89 (42.2%) were between greater than 18 months (medium). There was however, no statistical difference ages (x2 = 0.60, df = 1, p = 0.44). One hundred and thirty 130 (61.6%) of the chickens had coccidian parasite in their sample. Coccidiosis infection of these 74 (35.1%) were males while 56 (26.5%) were females but the difference was not found to be statistically significant (p>0.005). infection rate was higher among the Gallus-gallus domesticus 32 (38.8%) than the exotic breeds 48 (22.8%) and the difference was found to be statistically significant (p<0.05). The identification of coccidiosis based on their morphometry and region of intestine affected by coccidian species revealed that, E. tenella, E. nacatrix, E. brunetti, E. maxima measured 19 x 22.6, 14.2 x 16.7, 21.7 x 26.8 and 22.6 x 29.3 microns respectively. With E. tenella found in schizont and oocyst in ceca, E. nacatrix found in small intestine oocyst, intestine mucosa, E. brunetti in intestinal wall thicked, and E. maxima found in blood flecks in exudate as their region of intestine affected sites respectively. These findings may be useful to evaluate the infection potential when considering control programs in Benisheikh town and its vicinity.

ABSTRACT

Diagnostic imaging is an invaluable tool of diagnosis in medicine. Despite its value, diagnostic imaging equipments are expensive and difficult to maintain. To that extent, there is increasing concern among health policy planners that the growth in utilization of high-technology procedures, such as diagnostic imaging procedures, is a major factor responsible for the rapid growth in health care costs. Hence, it was the purpose of this study to determine the trends in workload and utilization rates of diagnostic imaging in the University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Rivers State, Nigeria between January 2010 and December 2012. Data comprising records of attendance of patients to the hospital clinics, the number of diagnostic imaging procedures, and workload measured in Relative Value Units (RVU) for the respective imaging modalities for the years 2010, 2011 and 2012 were analyzed. The results show that Conventional radiography is the most widely used imaging modality constituting over 50% of the total diagnostic imaging in the three year period. Ultrasound Scanning (USS) is the second most used modality (over 40%) followed by CT (over 2%), MRI (over 1%) and Mammography (less than 1%). In 2010 the overall diagnostic imaging utilization rate was 908.6 (@ 909) examinations per 10,000 patients. In 2012 the rate was 732.6 (@ 733), representing a 19.4% decrease over 3 years. It was concluded that some of the imaging modalities were not utilized optimally and did not justify government spending on them particularly, MRI, and Mammography although, it was established that equipment breakdowns contributed significantly to this trend.

ABSTRACT Antiretroviral therapy (ART) has significantly improved the heath conditions of those living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). This has encouraged more HIV-positive patients to be enrolled into care. Problem of side effects exists. Some of these side effects are mild and transient; few are serious and life-threatening. There are short term and long term adverse effects. Some short term effects include headache, nausea, diarrhea, mild central nervous system syndrome of lethargy or confusion. Long term toxicities include; myositis, peripheral neuropathy, pancreatitis, and hepatic steatosis. Severe adverse effects have contributed to non-adherence and have caused some patients to delay therapy. Physicians need information on toxicities of ART in order to appropriately weigh the option of second line drugs. HIV- positive patients should be well informed in order to allay anxiety and fear, thereby helping them to adjust to a more tolerable regimen. In conclusion, the numerous benefits of antiretroviral therapy such as decreased risk of progression to AIDS and improvement in physical and mental health far outweigh some adverse effects that may
