Abstract

This study evaluated the effects of ferrous nanoparticles (FeNPs) derived from Psidium guajava L. leaves on liver function in male Wistar rats. Fresh leaves were harvested from the Government Reservation Area (G.R.A), Wukari, Taraba State, washed, air-dried, and pulverized prior to FeNP preparation. Twenty-five male albino rats (140–190 g) were randomly assigned to five groups, with Group 1 serving as the control and Groups 2–5 receiving oral FeNP doses of 100, 250, 500, and 1000 ppm, respectively, for three weeks. Post-treatment, serum samples were collected under chloroform anaesthesia for biochemical and histological analyses. Liver function tests revealed non-significant differences (p > 0.05) in measured parameters between Groups 1 and 3, whereas Groups 2, 4, and 5 showed significant alterations (p < 0.05) compared with the control. Aspartate aminotransferase (AST) levels increased significantly in Groups 3–5, while Group 2 showed no significant change; alanine aminotransferase (ALT) levels increased significantly in all treated groups except Groups 3 and 4. Albumin concentrations were significantly elevated across all treated groups. Total bilirubin (TB) and indirect bilirubin (IDB) remained unchanged in Group 2 but increased significantly in Groups 3–5, whereas direct bilirubin (DB) did not differ in Groups 2 and 3 but rose significantly in Groups 4 and 5. Total protein (TP) levels were comparable between Groups 1 and 2 but were significantly higher in Groups 3–5. Malondialdehyde (MDA) levels did not differ significantly among groups, although apparent increases were observed, while catalase (CAT) activity was significantly elevated in all treated groups, peaking in Group 5. Superoxide dismutase (SOD) activity remained unchanged in Groups 2 and 3 but increased significantly in Groups 4 and 5. Histological examination revealed dose-dependent structural abnormalities in liver tissue, with the most pronounced damage observed in Group 5. Overall, FeNPs from Psidium guajava leaves induced dose-dependent alterations in liver function and antioxidant enzyme activity in male Wistar rats, with higher doses, particularly 1000 ppm, associated with marked biochemical disturbances and histological damage, suggesting potential hepatotoxicity at elevated concentrations and underscoring the need for further studies to define safe exposure thresholds and long-term effects.

Abstract

Hospital housekeepers play a vital role in maintaining hygiene and preventing infections within healthcare facilities, yet they are frequently exposed to biological hazards such as bloodborne pathogens, respiratory droplets, and contaminated waste, often without adequate protection or training. In Nigeria, particularly in tertiary institutions like Wukari Teaching Hospital, limited resources and weak enforcement of safety protocols further increase the vulnerability of non-clinical staff. This study aimed to assess the level of biological risk exposure among hospital housekeepers and identify gaps in personal protective equipment (PPE) usage, hygiene practices, and institutional support. A descriptive cross-sectional study was conducted among 60 hospital housekeepers at Wukari Teaching Hospital, with stratified random sampling ensuring representation across departments including wards, emergency, surgery, and outpatient units. Data were collected using structured questionnaires, direct observation checklists, and key informant interviews with infection control officers, and variables assessed included demographic data, exposure history, PPE usage, hygiene practices, and training experience. Quantitative data were analyzed using SPSS version 26, while qualitative responses were thematically coded. Findings revealed that 78.3% of housekeepers had direct contact with biological waste in the past six months, with blood, sputum, and vomit being the most common contaminants; only 41.7% consistently used full PPE, and just 36.7% reported that PPE was always available. Hand hygiene compliance was observed in 58.3% of cases, while 65% of respondents had never received formal infection control training, and only 30% felt adequately protected at work, with a majority suggesting improvements such as regular training, better supervision, and increased PPE supply. The study concludes that hospital housekeepers at Wukari Teaching Hospital face substantial biological risks due to frequent exposure, inconsistent PPE usage, and inadequate training, highlighting the urgent need for institutional reforms including structured infection control education, reliable PPE provision, and strict enforcement of hygiene protocols to protect this essential workforce and ensure a safe and resilient healthcare environment.

Abstract

Cassava (Manihot esculenta Crantz), a widely consumed staple in tropical regions, contains cyanogenic glycosides that release hydrogen cyanide (HCN) upon hydrolysis. Chronic exposure to cassava-derived cyanide has been implicated in neurodegenerative disorders, particularly affecting motor coordination and cerebellar function. This study investigates the neurotoxic effects of cassava cyanide on motor activity and cerebellar cytoarchitecture in albino Wistar rats. Thirty adult male rats were divided into three groups: control, low-dose cyanide (10 mg/kg), and high-dose cyanide (20 mg/kg), administered orally for 15 days. Motor performance was assessed using rotarod and open field tests, while cerebellar tissues were examined histologically using hematoxylin and eosin staining. Results revealed a dose-dependent decline in motor coordination and locomotor activity, with significant reductions in rotarod latency and open field distance in cyanide-treated groups compared to controls (p < 0.05). Histological analysis showed progressive Purkinje cell degeneration, vacuolation, and disrupted laminar architecture in the cerebellar cortex, particularly in the high-dose group. These findings suggest that cassava cyanide exerts neurotoxic effects on cerebellar neurons, impairing motor function through structural damage. The study underscores the importance of safe cassava processing and dietary interventions to mitigate cyanide-induced neurotoxicity in vulnerable populations.

Abstract

Maternal health remains a critical public health concern in Nigeria, where high rates of maternal morbidity and mortality persist despite ongoing interventions. This study aimed to assess the level of awareness and utilization of maternal health services among women in Wukari, Taraba State, Nigeria, to identify key barriers to service uptake, and to evaluate the influence of child welfare programs on antenatal care utilization. A cross-sectional descriptive survey was conducted among 250 women of reproductive age using structured questionnaires. Data were collected on socio-demographic characteristics, antenatal and maternity service utilization, barriers to access, and participation in child welfare programs, and were analyzed using descriptive statistics to generate frequencies and percentages. The findings showed that 85% of respondents were aware of antenatal services and 80% attended antenatal care during their last pregnancy; however, only 30% completed more than four visits. Skilled birth attendance was reported by 68% of respondents, whereas 16% delivered at home or with traditional birth attendants, and 60% received post-natal care. The major barriers to service utilization included distance to health facilities (60%), financial constraints (44%), lack of transportation (36%), poor attitude of health workers (28%), cultural and religious beliefs (24%), and lack of awareness (16%). In addition, women who participated in child welfare programs were 30% more likely to utilize antenatal services. These findings indicate that, despite relatively high awareness, maternal health service utilization remains suboptimal because of intersecting structural, economic, and sociocultural barriers. The study underscores the need to strengthen health infrastructure, improve transportation access, subsidize care, and expand community-based interventions, while also addressing cultural beliefs and health worker attitudes to improve maternal health outcomes in rural Nigeria.

Abstract

Snakebite envenomation frequently causes severe haematological disturbances through venom-induced haemotoxicity and systemic inflammatory responses. This study investigated the restorative effects of methanol leaf and root extracts of Lophira lanceolata on haematological indices in Bitis arietans venom-intoxicated Wistar rats. Thirty-six male rats were assigned to six groups: normal control, venom control, venom plus antiserum, venom plus leaf extract (200 mg/kg), venom plus root extract (200 mg/kg), and venom plus combined extracts. After 14 days of treatment, blood samples were analyzed for white blood cells, red blood cells, haemoglobin, platelets, and haematocrit. Venom intoxication induced significant leukocytosis, anaemia, thrombocytopenia, and reduced haematocrit, whereas treatment with L. lanceolata extracts, particularly the root extract, significantly improved these parameters toward normal levels. The root extract restored white blood cells to 8.40 ± 0.38 × 10⁹/L, red blood cells to 7.65 ± 0.30 × 10¹²/L, haemoglobin to 6.80 ± 0.20 g/dL, platelets to 425.50 ± 19.26 × 10⁹/L, and haematocrit to 20.50 ± 1.13%, indicating superior haematoprotective and anti-inflammatory effects relative to the leaf extract. Histological examination further confirmed these findings, showing that the extracts, especially the root, ameliorated venom-induced necrosis, hemorrhage, and congestion in liver and kidney tissues. These findings suggest that Lophira lanceolata, particularly its root extract, has therapeutic potential as a complementary intervention for managing snakebite-induced haematological disorders and tissue damage.

Abstract

Malnutrition remains a major public health challenge in Nigeria, particularly among children under five years of age, with serious consequences for morbidity, mortality, cognitive development, and long-term human capital. In rural communities such as Iware, Taraba State, this burden is intensified by poverty, poor feeding practices, limited access to healthcare, and low caregiver education. This study aimed to determine the prevalence of stunting, wasting, and underweight among children aged 0–59 months in Iware and to examine the associations between nutritional status and socio-economic factors, including household income, caregiver education, feeding practices, and recent illness episodes, while also assessing the coverage of exclusive breastfeeding and vitamin A supplementation. A cross-sectional design was employed, with a sample size estimated using Cochran’s formula at 200–400 children. A multistage sampling technique was used in which households were randomly selected and eligible children were stratified by age group. Data were collected through a structured questionnaire on socio-demographic characteristics, feeding practices, and household conditions, alongside anthropometric measurements of weight, height/length, and mid-upper arm circumference, with nutritional status classified according to WHO Growth Standards. Data collection was conducted over 2–4 weeks by trained enumerators following a pilot study, and the data were analyzed using SPSS and STATA through descriptive statistics, chi-square tests, and logistic regression. The findings revealed a high prevalence of malnutrition, with stunting at 35%, underweight at 30%, and wasting at 25%. Although 60% of children were exclusively breastfed and 65% had received vitamin A supplementation, 42.5% had experienced recent illness. Socio-economic findings further showed that 72.5% of households earned below ₦30,000 per month and that 20% of caregivers had no formal education. Statistical analysis indicated significant associations between malnutrition and low household income, poor caregiver education, and inadequate complementary feeding practices (p < 0.05). The study concludes that malnutrition among children under five in Iware is driven by the combined effects of chronic poverty, limited maternal education, suboptimal feeding practices, and frequent illness. These findings underscore the need for multi-sectoral interventions focused on nutrition education, economic empowerment, improved healthcare access, and community-based strategies tailored to rural populations.

Abstract

Mangifera indica (MI), popularly known as mango belong to the genus Mangifera and family Anacardiacea. The leaves, stem bark and roots are used as herbal medicines worldwide. Mango possesses anti-diabetic, anti-bacterial, anti- oxidant, anti-viral and anti-inflammatory properties. This research focuses on the hyperglycemic and antibacterial capacity of methanol stem bark extract of Mango tree in alloxan induced diabetic albino rats to combat its fatal consequences in humans. This work is carried out to determine the hypoglycemic capacity of methanol stem bark extract of Mangifera indica in alloxan-induced diabetic albino rats at different volumes (ml) of administration, to also determine the antibacterial capacity of methanol stem bark extract of Mangifera indica in alloxan-induced diabetic albino rats at different volumes (ml) of administration and to test the efficacy of methanol stem bark extract of Mangifera indica in alloxan-induced diabetic albino rats. Fresh stem bark (trunk) of Mangifera indica were collected in the Federal University Wukari school premises, were air dried for 21 days, pounded into powder, cold macerated in methanol, filtered and extract was gotten. 27 diseased-free (healthy) albino rats which were purchased at Yola, Adamawa State, were kept in different cages to enable proper analysis at the cause of the work. Results of liver function indices showed that treatments with 100 mg/kg, 200mg/kg and 400mg/kg body weight of Mangifera indica stem bark methanolic extract were able to restore liver function parameters at different levels of concentrations. Treatments with standard drug and all the doses of the extract were able to counteract the elevated effect of alloxan in some kidney parameters such as serum urea level at 200mg/kg with (25.23±1.98a) and (1.05 ±0.14a) for creatinine at 200mg/kg respectively. The result of this study shows that the stem back extract possessed as an agent for hypoglycaemic. These can serve as possible source of raw material for pharmaceutical products. However, the extract is found not to be harmful to the liver and kidney and should be used as health remedy for certain diseases such as hyperglycaemic and bacterial effects.

Abstract

HPLC techniques were employed to analyze the bioactive components of the chloroform leaf extract of Kalanchoe pinnata leaf from Takum in Taraba State. A botanist from Taraba State University's Department of Biological Sciences in Jalingo identified the plant leaves, which were then gathered, cleaned, and processed. Using cold maceration, extraction was done by weighing 1500g of the powdered leaf into 1 liter of ethanol and distill water, respectively. Until further investigation, the extracts were stored in a refrigerator in a firmly closed container. The injection valve was used for the HPLC analysis, and the conditions were 20 μl, a UV variable wavelength detector (set at 300 nm), reprosol 100 C8mn, 5 μm 4.6 x 150mm column (30°C), and sensitivity of 0.001. Phosphate buffer (v/v) was used as an aqueous solvent (A) and CH3CN as an organic solvent (B) in HPLC. Gradient elution of the analytes occurred at a flow rate of 1 milliliter per minute. Software generated chromatograms. Operating temperature of the HPLC instrument was room temperature (23 ± 2°C). After injecting 20 μl of each diluted extract into the HPLC three times, the average peak areas were produced and utilized for quantification. Based on the HPLC analysis, the chloroform leaf extract of Kalanchoe pinnata contained the following bioactive constituents: quercetin, gallic acid, and chlorogenic acid. Additionally, the presence of vitamins B1 and B3 was also noted. The different bioactive constituents eluted at different retention times, and their respective amounts were also detected.
