The novel coronavirus, SARS-CoV-2, which causes COVID-19, is seen world-wide. In developing countries, adequate health facilities and staff numbers are a concern. Ghana recorded its first 2 cases of COVID-19 on 12 March 2020. On 30 March 2020, a partial lockdown for 14 days was imposed and later extended along with other measures. By the end of the initial lockdown, 19 April 2020, an estimated 86,000 people had been traced and 68,591 tests performed. Of the 68,591 tests, there were 1,042 (1.5%) positive cases, 9 deaths, and 99 recoveries, with Ghana ranked number one among African countries in administering tests per million people. Ghana’s effective track and trace system, as well as lockdown and other measures, have helped limit mortality with only 85 recorded deaths by 23 June 2020. Scientists from three facilities of the University of Ghana have also successfully sequenced the genomes of COVID-19 from 15 confirmed cases, and the Food and Drugs Authority in Ghana have also helped address shortages by fast-tracking certification of hand sanitizers and local production of 3.6 million standardized personal protective equipment. There has also been the development of prototypes of locally-manufactured mechanical ventilators to meet local need at intensive care units. Most people have also resorted to changing diets and the use of supplements to boost their immune system. Although initial results are encouraging, further research is needed to understand the dynamics of COVID-19 in Ghana and provide additional guidance.

Background. Annona muricata L. has been reported to possess antitumor and antiproliferative properties. Not much work has been done on its effect on BPH-1 cell lines, and no in vivo studies targeting the prostate organ exist. The study determined the effect of A muricata on human BPH-1 cells and prostate organ. Methods. The MTT assay was performed on BPH-1 cells using the aqueous leaf extract of A muricata. Cells (1 × 10⁵ per well) were challenged with 0.5, 1.0, and 1.5 mg/mL extract for 24, 48, and 72 hours. Cell proliferation and morphology were examined microscopically. BPH-1 cells (1 × 10⁴ per well) were seeded into 6-well plates and incubated for 48 hours with 0.5, 1.0, and 1.5 mg/mL A muricata extract. Reverse transcriptase polymerase chain reaction was performed using mRNA extracted from the cells. Possible target genes, Bax and Bcl-2, were examined. Twenty F344 male rats (≈200 g) were gavaged 30 mg/mL (10 rats) and 300 mg/mL (10 rats) and fed ad libitum alongside 10 control rats. Rats were sacrificed after 60 days. The prostate, seminal vesicles, and testes were harvested for histological examination. Results. Annona muricata demonstrated antiproliferative effects with an IC₅₀ of 1.36 mg/mL. Best results were obtained after 48 hours, with near cell extinction at 72 hours. Bax gene was upregulated, while Bcl-2 was downregulated. Normal histological architecture was observed for all testes. Seminal vesicle was significantly reduced in test groups ( P < .05) and demonstrated marked atrophy with increased cellularity and the acinii, empty of secretion. Prostate of test groups were reduced with epithelial lining showing pyknotic nucleus, condensation, and marginalization of the nuclear material, characteristic of apoptosis of the glandular epithelium. Furthermore, scanty prostatic secretion with flattening of acinar epithelial lining occurred. Conclusion. Annona muricata has antiproliferative effects on BPH-1 cells and reduces prostate size, possibly through apoptosis.

Acute toxicity studies of aqueous leaf extract ofPhyllanthus niruri: Phyllanthus niruriis a plant with medicinal properties. It is often used to treat mild malaria and the elimination of renal stones. However, studies on its toxicity are scarce. The study was carried out to determine if the aqueous leaf extract ofP. niruriadministered to female Sprague-Dawley rats would illicit evidence of toxicity. Fifteen female rats weighing 150-200 g were divided into 3 groups. Rats in Group 1 were given a single low dose (LD) of 2 000 mg/kg b.w. of the extract by oral gavage within 24 hrs. Rats in Group 2 were given a single high dose (HD) of 5 000 mg/kg b.w. of the extract by oral gavage within 24 hrs. Rats in Group 3 were not given any extract but drinking water and served as the control group (C). All the rats were observed for signs of toxidromes for 14 days. On the 15^thday, all the rats were sacrificed. Body organs were harvested for macroscopic examination. Urine and blood samples were drawn and analyzed. Hematological tests performed included full blood count and hemoglobin. Biochemical examinations included bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, globulin, alkaline phosphatse (ALP), γ-glutamyltranspeptidase (GGT), urea, and creatinine. The results of the three groups were not significantly different. Examination of the various body organs did not show any abnormality. Thus no toxicity was observed at the levels administered. The LD₅₀of the aqueous extract is > 5 000 mg/kg. b.w.

Background: Globally, the application of medicinal plants in the management of acute and chronic wounds can be considered a common occurrence in most traditional medicine practices. In view of this, many plants in the tropical and subtropical regions have been screened for their wound-healing activities. Consequently, plants having antimicrobial activity against multidrug-resistant (MD-R) pathogens can be considered great assets. Therefore, this study evaluated ethanolic and aqueous extracts of five medicinal plants (Psidium guajava, Myrianthus arboreus, Alchornea cordifolia, Momordica charantia, and Justicia flava) for their antimicrobial activities against MD-R bacterial pathogens isolated from post-operative wounds; Methods: This involved the aqueous and ethanolic extraction of the selected medicinal plants. Preliminary phytochemical constituents of the plants were examined. The agar well diffusion method was then used to determine the antibacterial activity of the leaves against reference strains (Escherichia coli ATCC 25922, Salmonella typhi ATCC 19430, Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 25923, and a Methicillin-Resistant Staphylococcus aureus strain) as well as the MDR clinical isolates (E. coli, P. aeruginosa, S. aureus and CoNS) from the wounds; Results: The preliminary phytochemical analysis of the leaves showed the presence of saponins, phenolics, and reducing sugars in almost all the plants tested. All plant extracts were observed to have some antimicrobial activity against at least one reference strain. For the clinical MDR isolates, A. cordifolia from this study showed highest inhibition to growth of all bacteria used. Activity of J. flava against S. aureus was highest as compared to that of E.coli and P. aeruginosa. Similar observation was made for M. arboreus, P. guajava and M. charantia where the highest activity was observed against S. aureus; Conclusion: This study has mainly shown that P. guajava, M. arboreus, A. cordifolia, M. charantia, and J. flava exhibits antimicrobial activities against MD-R bacterial pathogens isolated from post-operative wounds. Also, these plants has bioactive phytochemical compounds with potential medicinal values for the treatment of numerous infections. Therefore, these plants may be helpful in the management of acute and chronic wounds, especially in traditional medicine practices.

Introduction: The etiology of benign prostatic hyperplasia (BPH) remains a mystery to scientists; estrogen/androgen imbalance in aged men has been implicated. Methods: Thirty (30) apparently healthy men and newly diagnosed BPH patients were recruited from the Ghana Police Hospital. Lower urinary tract syndrome (LUTS) and prostate volume were assessed via the prostate symptom score sheet (IPSS) and abdominopelvic scan, respectively. Laboratory assays for total prostate specific antigen (tPSA) and hormones [androstenedione (AED), testosterone (T), dihydrotestosterone (DHT), androstanedioladiol (3α-adiol), androstanediol (3β-diol), estrone (E1) and estradiol (E2)] were performed via ELISA techniques. Non-parametric analyses were employed. p < 0.05 was considered significant. Results: AED was significantly higher in controls compared to the BPH patients. AKRIC2 (3α-diol/DHT) was significantly higher in the BPH group (p < 0.001) whiles AKRIC1 (3β-diol/DHT) was significantly lower. Estradiol was significantly higher in BPH (p= 0.029). Age correlated negatively with T, while a negative correlation was observed between TIPSS and 3β-diol and AKRIC1. Also, prostate volume correlated negatively with fT.tPSA correlated positively with E2 and aromatase activity (E2/T) and negatively with fT. On multiple linear regression, DHT and 3β-diol remained independent predictors for TIPSS and fT for tPSA. Conclusion: Estrogens and androstanediols seem to play a role in BPH development.
