An 81-year-old male presented to the Emergency Department with urinary retention, subsequent to passing blood clots. A three-way catheter was inserted for continuous bladder irrigation. 48 hours later he deteriorated, with worsening tachypnea and hypoxaemia. Clinical examination and chest x-ray suggested pulmonary odema, managed with intravenous furosemide, and non-invasive ventilation. His irrigation circuit-chart showed he had received 10 litres Normal Saline via the afferent limb, but only 3 litres recorded at the efferent limb. It was suspected the catheter was adjacent to a vascular-cystic interface, however an urgent contrast CT revealed the irrigating catheter perforating the bladder, being situated in the abdominal cavity (see 3 images). His arterial blood-gas analysis demonstrated the expected normal anion-gap academia, however his Strong Ion Difference calculations, sodium-chloride difference of 13 and a normal albumin level, perfectly demonstrated the expected calculated BE of -13. The catheter was withdrawn, and the patient made a full recovery.

This study aims at investigating the antipyretic activity of different solvent fractions of the root bark of Rutideaparviflora(Rubiaceae). This plant is used ethno-botanically by the people of Ethiope East-West Local Government Area of Delta State, Nigeria to treat various ailments such as inflammation, fever and pain. This necessitated this research to validate its local use, due to the scanty literature and information present about this plant. It has also shown some anti-cancer and anti-inflammatory activity in previous researches. The present study is a randomized control study. Acetic acid induced writhing was employed for analgesic testing. Acetic acid was used to induce writhing in Wistar rats which were divided into fourteen (14) groups. The groups were administered extracts and fractions of the plant (200 mg/kg and 400 mg/kg). The animals were observed for number of writing movements and the percentage writhing was calculated. Baker’s yeast induced pyrexia was employed for the antipyretic testing. The animal groups were administered extracts and fractions of the plant (200 mg/kg and 400 mg/kg), with Paracetamol as the standard drug (100 mg/kg) and Normal saline (control) for both experiments. The body temperature of the rats was measured rectally over a period of five (5) hours. All values of P<0.05 were taken as significant. The organic extract, aqueous extract and various fractions (n-hexane, ethyl-acetate, n-butanol and aqueous) produced significant inhibition of writhing responses and pyrexia in a dose dependent manner and time dependent manner respectively. The aqueous extract at a dose of 400mg/kg showed the greatest reduction in writhing, 91.58% compared to the standard drug (paracetamol) which may suggest that the fraction possesses better efficacy than paracetamol as an analgesic. The observed activities could be attributed to these bioactive compounds: Palmatine, Urs-12-ene-24-oic-3-oxo-methyl ester and Gallic acid contained in R. parviflora.

Plants have played a significant role in maintaining human health and improving the quality of human life. Therefore, this present study seeks to evaluate the role of its alkaloid fraction in the hypothalamic-pituitary-testicular axis after dichlorvos poisoning in mice. A total of 25 male mice, weighing approximately 20-30 g, were randomly assigned into 5 groups of 5 mice each (Groups A, B, C, D and E). Mice in groups A served as control and received normal saline while groups B, C and E. received 5 mg/kg of dichlorvos daily for 14 days. Mice in group D received 200mg/ kg of Alkaloid extract of Mimosa pudica (AEMM) for 14 days. At the end of the experiment, all animals were sacrificed and Hypothalamus, Pituittary and Testes were excised for histological process. Sperm from cauda epididymidal duct on one side was collected and used for spermatological studies and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results showed significance difference (p<0.05) in sperm motility, sperm life death ratio groups when compared with their controls and no significance difference in sperm volume when compared with control. Histological studies reveal distortion in hypothalamuss, pituitary and testes in dichlorvos administration group compared with control rats while mimosa showed a ameliorative effect when co-administered with dichlorvos. In conclusion, the alkaloids from Mimosa (AEM) leaves enhanced the released of gonadotropins by the cordial action of the hypothalamus-pituitary axis for the reversed of Dichlorvos effect.

Local Nigerian men have been using AuriculariaPolytricha as a treatment for sexual dysfunction without supporting evidence from scientific experiments. This study was to investigate the effect of ethanolic extract of A. Polytricha on testicular DNA expression and some oxidative stress markers using STZ-Induced diabetic rats as a model. The experiment included six groups, Group A (Normal Control, treated with normal saline), Group B (treated with 65mg/kg.bw of STZ), Groups C, D, and E (treated with 250mg/kg.bw, 500mg/kg.bw, 1000mg/kg.bw AP after inducing diabetics), and Group F (treated with 40mg/kg.bw metformin after inducing diabetics). The experiment lasted for 35 days. After termination of the experiment, Fuelgen nuclear reaction was used for DNA demonstration to assess testicular DNA distribution while serum Superoxide Dimutase (SOD), Catalase and Melondialdehyde where evaluated using reagent based antioxidant enzyme assay. Results reveals that SOD and Melondialdehyde activities were remarkably (p<0.05) higher in diabetic control animals when compared with the normal control group. Values in Groups C, D and F that were administered with 250, 500mg/kg.bw A. polytricha and metformin respectively were also significantly (p<0.05) increased when compared with the normal control group. However, diabetic animals placed on 1000mg/kg.bw A. polytrichadid not show any statistical significance in comparison with normal control group but was remarkably (p<0.01) decreased when compared to the diabetic group that received low dose A. polytricha, an indication that the reversal is dose dependent. Catalase concentration in diabetic control animals was remarkably (p<0.05) higher when compared to the normal control but was not significantly (p<0.05) different in groups D (DM+500mg/kg.bw A. polytricha) and E (DM+1000mg/kg.bw A. polytricha) when compared with the normal control group. Diabetic control animals showed reduced magenta colour intensity of DNA and increased clustering and cross linking of DNA strands when compared with the normal control. However the degree of cross link in DNA strands was reduced in the diabetic animals placed on 1000mg/kg.bw A. polytrichawhen compared with the diabetic control group. Reversal in DNA damage and values of serum oxidative stress markers following administration of graded doses of A. polytricha could be attributed to essential phytochemical and therapeutic constituents in A. polytricha like polyphenol and flavonoid which can be found useful in prevention and treatment of diabetes induced testicular dysfunction. In summary, AP can contribute to a reversal in DNA damage and levels of serum oxidative stress markers in treating diabetes-induced testicular dysfunction.

Since oxidative stress impairs the cardiovascular function, the hypothesis from the present study is that the treatment of paraquat-exposed adult Wistar rats with methanolic extract of Abelmoschus esculentusseed would reduce paraquat-induced cardiovascular damage. Thirty healthy female Wistar rats weighing 120-150 g were randomly assigned into 6 groups of 5 rats each (Groups A, B, C, D, E and F). Rats in groups A served as control and received normal saline while groups B, C, D, E and F received a single dose of paraquat (7mgkg-1i.p.). Rats in group B was sacrificed 24hours following paraquat administration while daily administration of 100 mg kg-1and 200 mg kg-1 of methanolic extract of Abelmoschus esculentusseed extract were given orally to groups C and D while group E received daily oral dose of Vitamin E at 100mgkg-1 and group F was left untreated. Histological and biochemical preparations of the heart was made and data were expressed as mean± SEM. Significant difference was set at p<0.05. Results showed no significance difference (p<0.05) in nitric oxide activity, Glutathione reductase activity, and troponin I activity across the paraquat-exposed groups when compared with control. Histological studies reveal distortion of normal cardiac histo-architecture in paraquat-exposed group B compared with control rats while Abelmoschus esculentus reversed these changes in other treated groups. The study concluded that paraquat caused significant distortion of the cardiac histo-architecture and methanolic extract of immature Abelmoschus esculentus seed had antioxidant and ameliorative effects similar to Vitamin E on paraquat-induced myocardial injury.

Background: Oral ingestion of zinc oxide nanoparticles (ZnONPs) may lead to serious liver injury. Vitamin E (VE) is an important antioxidant factor that can reduce such damage. Aim: This study aimed to evaluate the possible changes that could take place in the liver of adult male albino rats after oral ingestion of ZnONPs and elucidate the potential protective role of VE against such damage. Material and Methods: Forty eight male albino rats were divided into four groups of 12 animals each. Group (1) served as control group and received normal saline. Group (2) “VE-treated” received 100 mg/kg/day of VE dissolved in normal saline by oral gavage for 21 days. Group (3) “ZnONPs-treated” received a daily dose of ZnONPs dispersed in the fresh sterilized physiological saline solution 1mg/kg for 5 constitutive days. Group (4) “concomitant ZnONPs and VE-treated” was pretreated with VE 100 mg/kg/day for 14 days followed by the same dose of ZnONPs as in group (3) for 5 days. The extent of hepatic damage was evaluated by histological and immunohistochemical examination of liver samples and serological analysis of liver enzymes. Results: Body weights and liver weights showed very highly significant decrease (P <0.001) in the ZnONPs-treated group. The histological results in ZnONPs-treated group revealed congested dilated central veins and blood sinusoids, loss of normal arrangement of hepatocytes and most of hepatocytes showed marked vacuolated cytoplasm with darkly stained nuclei. Portal area affection was in the form of congested dilated portal veins with bile duct hyperplasia and cellular infiltration. There was an increase in the mount of blue stained collagen fibers around central veins together with strong positive reaction for Caspase 3 in ZnONPs-treated group. Similarly biochemical analysis indicated that the levels of serum aminotransferase (AST &ALT) significantly increased in ZnONPs-treated group when compared with other groups. Rats pretreated with VE showed improvement of the histological findings and biochemical parameters. Conclusion: Ingestion of ZnONPs could be associated with serious liver affection and pretreatment with VE is suggested to induce some improvement of such deleterious changes.
