Abstract
Mood and anxiety disorders are leading causes of disability worldwide and are major contributors to the global burden of diseases. Neuropeptides, such as oxytocin and opioid peptides, are important for emotion regulation. Previous studies have demonstrated that oxytocin reduced depression- and anxiety-like behavior in male and female mice, and opioid receptor activation reduced depression-like behavior. However, it remains unclear whether the endogenous opioid system interacts with the oxytocin system to facilitate emotion regulation in male and female mice. We hypothesized that opioid receptor blockade would inhibit the anxiolytic- and antidepressant-like effects of oxytocin. In this study, we systemically administered naloxone, a preferential μ-opioid receptor antagonist, and then intracerebroventricularly administered oxytocin. We then tested mice on the elevated zero maze and the tail suspension tests, respective tests of anxiety- and depression-like behavior. Contrary to our initial hypothesis, naloxone potentiated the anxiolytic-like, but not the antidepressant-like, effect of oxytocin. Using a selective μ-opioid receptor antagonist, D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2, and a selective κ-opioid receptor antagonist, norbinaltorphimine, we demonstrate that μ-opioid receptor blockade potentiated the anxiolytic-like effect of oxytocin, whereas κ-opioid receptor blockade inhibited the oxytocin-induced anxiolytic-like effects. The present results suggest that endogenous opioids can regulate the oxytocin system to modulate anxiety-like behavior. Potential clinical implications of these findings are discussed.

A Review of the Popular Uses, Anatomical, Chemical, and Biological Aspects of Kalanchoe (Crassulaceae): A Genus of Plants Known as "Miracle Leaf". Molecules 2023; 28:5574. [PMID: 37513446 PMCID: PMC10383218 DOI: 10.3390/molecules28145574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 07/15/2023] [Accepted: 07/19/2023] [Indexed: 07/30/2023] Open
Abstract
Species of the genus Kalanchoe have a long history of therapeutic use in ethnomedicine linked to their remarkable healing properties. Several species have chemical and anatomical similarities, often leading to confusion when they are used in folk medicine. This review aims to provide an overview and discussion of the reported traditional uses, botanical aspects, chemical constituents, and pharmacological potential of the Kalanchoe species. Published scientific materials were collected from the PubMed and SciFinder databases without restriction regarding the year of publication through April 2023. Ethnopharmacological knowledge suggests that these species have been used to treat infections, inflammation, injuries, and other disorders. Typically, all parts of the plant are used for medicinal purposes either as crude extract or juice. Botanical evaluation can clarify species differentiation and can enable correct identification and validation of the scientific data. Flavonoids are the most common classes of secondary metabolites identified from Kalanchoe species and can be correlated with some biological studies (antioxidant, anti-inflammatory, and antimicrobial potential). This review summarizes several topics related to the Kalanchoe genus, supporting future studies regarding other unexplored research areas. The need to conduct further studies to confirm the popular uses and biological activities of bioactive compounds is also highlighted.

Abstract
Mood disorders can be considered among the most common and debilitating mental disorders. Major depression, as an example of mood disorders, is known to severely reduce the quality of life as well as psychosocial functioning of those affected. Its impact on the burden of disease worldwide has been enormous, with the World Health Organisation projecting depression to be the leading cause of mental illness by 2030. Despite several studies on the subject, little has been done to contextualise the condition in Africa, coupled with the fact that there is still much to be understood on the subject. This review attempts to shed more light on the prevalence of depression in Sub-Saharan Africa (SSA), its pathophysiology, risk factors, diagnosis and the experimental models available to study depression within the sub-region. It also evaluates the contribution of the sub-region to the global research output of depression as well as bottlenecks associated with full exploitation of the sub region's resources to manage the disorder.

Cuf Leaves in murine models. JOURNAL OF ETHNOPHARMACOLOGY 2022; 283:114640. [PMID: 34606947 DOI: 10.1016/j.jep.2021.114640] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 09/10/2021] [Accepted: 09/11/2021] [Indexed: 02/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Advancement in cancer therapy has improved survival among patients. However, use of anticancer drugs like anthracyclines (e.g., doxorubicin) is not without adverse effects. Notable among adverse effects of doxorubicin (DOX) is cardiotoxicity, which ranges from mild transient blood pressure changes to potentially serious heart failure. Anecdotal reports suggest that Kalanchoe integra (KI) may have cardio-protective potential. AIMS OF THE STUDY This study sought to determine the cardio-protective potential of KI against doxorubicin-induced cardiotoxicity and also examined any possible genotoxic potential of KI in selected organs. Additionally, the nitric oxide modulatory potential of KI was assessed. MATERIALS AND METHODS The leaves of KI were collected, air-dried, pulverised and extracted using 70% ethanol. High-performance liquid chromatography (HPLC) fingerprinting was done for KI. Also, the single-cell gel electrophoresis assay (Comet assay) was employed to ascertain the genotoxic potential of KI. In assessment of cardio-protective potential of KI against doxorubicin-induced cardiotoxicity, a total of 42 female Sprague-Dawley rats were put into 7 groups (n = 6). Group I: vehicle control, received normal saline (1 mL/kg p.o) for 30 days. Group II: toxic control, received DOX (20 mg/kg i.p.) once on the 29th day. Group III: KI control, received KI (300 mg/kg p.o) for 30 days. Group IV: vitamin E control, received vitamin E (100 mg/kg p.o) for 30 days. Group V: KI treated-1, received KI (300 mg/kg p.o) for 30 days and DOX (20 mg/kg i.p) on the 29th day. Group VI: KI treated-2, received KI (600 mg/kg p.o) for 30 days and DOX (20 mg/kg i.p) on the 29th day. Group VII: vitamin E treated, received vitamin E (100 mg/kg p.o) for 30 days and DOX (20 mg/kg i.p) on the 29th day. Thirty-six (36) hours after last administration, rats were sacrificed. Blood samples were taken via cardiac puncture to determine levels of aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), creatine kinase (CK), lactate dehydrogenase (LDH), enzymatic antioxidants such as glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT). Nitric oxide level was also determined. Hearts of rats in each group were excised and taken through histopathological examination. RESULTS In the HPLC fingerprint analysis, 13 peaks were identified, and peak with retention time of 24.0 min had the highest peak area (3.223 x104 mAU). Comet assay showed that the KI extract was non-genotoxic. Pretreatment with KI protected rats against doxorubicin-induced cardiotoxicity as evidenced by the low levels of AST, ALT, ALP, CK and LDH compared with the controls (p < 0.05). SOD, CAT and GPX levels were also high for rats administered KI extracts, further showing that KI protected rats against doxorubicin-induced cardiotoxicity. KI also inhibited nitric oxide levels at 300 mg/kg and 600 mg/kg effective doses. Histological examination revealed that rats pretreated with KI showed no signs of abnormal myocardial fibres (shape, size and configuration). CONCLUSION Ethanolic (70%) leaf extract of KI showed no genotoxic potential and possessed cardioprotective effects against doxorubicin-induced cardiotoxicity in Sprague-Dawley rats. KI also inhibited nitric oxide production, thus, a potential nitric oxide scavenger.

Abstract
Several studies have supported the preventive and therapeutic values of phenolic compounds including chlorogenic acid, syringic acid, vanillic acid, ferulic acid, caffeic acid, luteolin, rutin, catechin, kaempferol, and quercetin in mental disorders. Since these secondary metabolites are reported as the phenolic compounds of Artemisia dracunculus (A. dracunculus) and Stachys lavandulifolia (S. lavandulifolia), the main aim of this study was the evaluation and comparison of the phenolic contents, flavonoids, and antidepressant-like activity of Artemisia dracunculus with Stachys lavandulifolia. Antidepressant-like activity of the extracts was evaluated in the forced swimming test (FST) and the tail suspension test (TST). Moreover, the open field test was conducted to evaluate the general locomotor activity of mice following treatment with the extracts. Since phenolic compounds and flavonoids play main roles in pharmacological effects, the phenolic and flavonoid contents of the extracts were measured. Though significant difference between the phenolic contents of the extracts was not observed, but S. lavandulifolia exhibited higher flavonoid contents. Animal treatment with extracts decreased the immobility times in both FST and TST compared to the vehicle group without any significant effect on the locomotor activity of animals. Also, S. lavandulifolia at 400 mg/kg showed higher potency in both tests compared to A. dracunculus. Our results provided promising evidence on the antidepressant-like activity of both extracts which could be related to flavonoids as the main components of the extracts, but more studies need to be conducted to specify the main compounds and the mechanisms involved in the observed effects.

Abstract
Synedrella nodiflora (SNE) has been used traditionally for many neurological conditions and some of these neuroactive effects have been scientifically substantiated. The usefulness of SNE in depression has however not been investigated despite the availability of data in other disease models indicating it may be useful. The present study therefore examined the effect of SNE in acute murine models of depression and the possible mechanisms mediating its activities in these models. Preliminary qualitative phytochemical and high performance liquid chromatography (HPLC) screening were conducted on SNE. The behavioural effects of SNE (100, 300 and 1000 mg/kg) pre-treated mice were examined in the forced swimming (FST) and tail suspension (TST) tests. Behavioural events such as mobility (swimming, climbing, curling and climbing), and immobility, were scored. The possible involvement of monoamines in the effects of SNE was assessed in the TST by pre-treating mice with α-methyldopa, reserpine and para-chlorophenylalanine (pCPA) in separate experiments. Flavonoids, tannins, saponins, alkaloids, cardiac glycosides, coumarins, triterpenes, sterols, anthraquinones and phenolic compounds were present in SNE. HPLC analysis revealed the presence of two major constituents observed at retention times 42.56 and 46.51 min, with percentage composition of 45.72% and 36.88% respectively. SNE significantly reduced immobility scores in both FST and TST, suggesting antidepressant effects. The antidepressant properties of SNE were reversed by the pre-treatment of α-methyldopa, reserpine and pCPA, suggesting a possible involvement of monoamines (noradrenaline and serotonin) in its mechanism(s) of actions. SNE exhibits antidepressant effects, possibly mediated through an interplay of enhancement of noradrenergic and serotoninergic mechanisms.
