This article reviewed the folk medical value of Spondias mombin with the correlated research findings on the uses of Spondias mombin. Most of the folk uses had been scientifically proven in most of the regions where those beliefs are based. The plant was described with habitat, the local uses including the uses of its parts mentioned. We reviewed the ethnomedicinal uses, the biological activities and the phytochemistry of Spondias mombin.

Background: This study evaluated the prevalence, predictors and effects of Shift Work Sleep Disorder (SWSD) among nurses in a Nigerian teaching hospital. Methods: Eighty-eight nurses (44 each from the pool of shift and non-shift nurses), who emerged by simple random sampling, participated in the study. Socio-demographic data and health complaints were obtained with questionnaires. Each participant was assessed with Epworth sleepiness scale (ESS), insomnia severity index (ISI) and sleep log, while SWSD cases were ascertained by applying the International Classification of Sleep Disorders (ICSD-2) criteria. Body mass index, blood pressure, body temperature and salivary cortisol levels were also determined. Results: Generally, results showed that the shift group; comprising of shift nurses, recorded higher values of biophysical profiles and more health complaints than the non-shift group (control); comprising of non-shift nurses. Also, 19 (43.2%) of the shift nurses fulfilled the criteria for SWSD, on this basis, the shift group was divided into two: SWSD (n = 19) and No SWSD (n = 25). And within the shift group, the SWSD group had higher systolic (p = 0.014), diastolic (p = 0.012), and mean arterial (p = 0.009) blood pressures; they also recorded higher temperature (p = 0.001) , higher salivary cortisol levels (p = 0.027) and more health complaints. Conclusion:The results of this study indicate that rotating shift work among nurses is associated with increased level of health complaints and physiologic indices of stress as well as sleep impairment.

The aim of this study was to substitute costly and hazardous compound-xylene, used as clearing agent, with less costly compounds (mixture of xylene and kerosene) having less toxicity and without compromising the cellular integrity and staining characteristics of the sections. Tissues (liver and kidney) obtained from a presumable healthy adult Wistar rat, were fixed in 10% formol saline, separated in to five groups (A, B, C, D and E) and processed for light microscopic study adopting H & E staining procedure. During the clearing section, groups A, B, C, D and E were respectively cleared in solvent 1 (xylene only), solvent 2 (70ml xylene : 30ml kerosene), solvent 3 (50ml xylene : 50ml kerosene), solvent 4 (30ml xylene : 70ml kerosene) and solvent 5 (kerosene only). Our result revealed that tissues in groups A, B and C were properly cleared without any morphological impairment. The staining characteristics were also observed to be very bright. Groups D and E however presented poor staining intensity with reduced cellular details. Semistained transparent patches were also noticed. It is inferred from the present investigation that a mixture of xylene and kerosene could be employed in the clearing of tissues only at the prescribed ratio i.e. solvent 2 and solvent 3 without posing any health risk or compromising the cellular integrity.

AIM:To determine the effects of aqueous extract of Allium sativum bulbs (AEASAB) on pituitary-testicular injury and dysfunction in Wistar rats with lead-induced reproductive disturbances.MATERIALS AND METHODS:Male Wistar rats were divided into 7 groups such that the control group received propylene glycol at 0.2 ml/100 g intraperitoneally for 10 consecutive days, the toxic group received lead (Pb) alone at 15 mg/kg/day via intraperitoneal route for 10 days while the treatment groups were pretreated with lead as the toxic group after which they received graded doses of the extract at 50, 100 and 200 mg/kg/day via oral route for 28 days.RESULTS:Pb administration induced significant deleterious alterations in the antioxidant status of the brain and testis, sperm characterization (counts, motility and viability) as well as reproductive hormones (FSH, LH and testosterone) of exposed rats (p < 0.05). These were significantly reversed in the AEASAB-treated groups (p < 0.05). Also, there was marked improvement in the Pb-induced vascular congestion and cellular loss in the pituitary while the observed Pb-induced severe testicular vacuolation was significantly reversed in the representative photomicrographs, following administration of the extract.CONCLUSION:AEASAB treatment ameliorated the pituitary-testicular injury and dysfunction in Wistar rats with Pb-Induced reproductive disturbances.

Background The increasing incidence of chemically induced infertility is both a social threat and a threat to the continuation of life itself. Treatment or management therapy is often expensive. This study investigated the effects of acetone extract of a local plant (Curcuma longa) in a Wistar rat model of cimetidine‐induced pituitary‐testicular dysfunction. Methods Thirty‐five male Wistar rats were divided into 7 groups of 5 rats. After a phytochemical screening of an acetone extract of C. Longa, cimetidine and the extract at three doses, 200, 400 and 600 mg/kg, were orally co‐administered to the rats for 28 consecutive days. Comparisons were made (at P < 0.05) against a control (2 mL/kg distilled water), a standard treatment group (cimetidine + 50 mg/kg vitamin C), a toxic group (60 mg/kg cimetidine) and a group receiving extract alone. Results Cimetidine administration was associated with deleterious alterations to sperm motility, sperm count and sperm viability, as well as derangements in the plasma levels of FSH, LH and testosterone (P < 0.05). Both brain and testicular GSH and TBARS levels were significantly altered following cimetidine administration, and distortions were seen in the pituitary and testicular histoarchitecture. These changes were significantly normalized by co‐administration of graded doses of the extract, with an associated improvement of both pituitary and testicular histology. Conclusion Acetone extract of C. Longa normalized cimetidine‐induced pituitary‐testicular dysfunction in Wistar rats. This presents the extract as a potential nutraceutical choice against chemically induced reproductive toxicity.
