The present study was designed to investigate the effects of electroacupuncture (EA) on depressive-like and anxiety-like behaviours and neural progenitors in the hippocampal dentate gyrus (DG) in a chronic unpredictable stress (CUS) rat model of depression. After being exposed to a CUS procedure for 2 weeks, rats were subjected to EA treatment, which was performed on acupoints Du-20 (Bai-Hui) and GB-34 (Yang-Ling-Quan), once every other day for 15 consecutive days (including 8 treatments), with each treatment lasting for 30 min. The behavioural tests (i.e., forced swimming test, elevated plus-maze test, and open-field entries test) revealed that EA alleviated the depressive-like and anxiety-like behaviours of the stressed rats. Immunohistochemical results showed that proliferative cells (BrdU-positive) in the EA group were significantly larger in number compared with the Model group. Further, the results showed that EA significantly promoted the proliferation of amplifying neural progenitors (ANPs) and simultaneously inhibited the apoptosis of quiescent neural progenitors (QNPs). In a word, the mechanism underlying the antidepressant-like effects of EA is associated with enhancement of ANPs proliferation and preserving QNPs from apoptosis.

The potential anxiolytic and anti-depressive activity of CMP1 was studied in the elevated plus-maze test and in the forced swimming test. Furthermore, CMP1 sedative activity was evaluated in pentobarbital treated animals; the effect of CMP1 on spontaneous motor activity (total locomotion) was also evaluated. Our data show that CMP1, at doses that did not affect locomotion, was able to induce anxiolytic and sedative, but not anti-depressive effects. In conclusion, our results represent first evidence for an anxiolytic activity of this diterpenoid from Salvia cinnabarina.

Lepidagathis hyalina Nees is used locally in Ayurvedic medicine to treat coughs and cardiovascular diseases. This study explored its pharmacological potential through in vivo and in vitro approaches for the metabolites extracted (methanolic) from the stems of L. hyalina. A qualitative phytochemical analysis revealed the presence of numerous secondary metabolites. The methanol extract of L. hyalina stems (MELHS) showed a strong antioxidative activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and reducing power assays, and in the quantitative (phenolic and flavonoid) assay. Clot lysis and brine shrimp lethality bioassays were applied to investigate the thrombolytic and cytotoxic activities, respectively. MELHS exhibited an expressive percentage of clot lysis (33.98%) with a moderately toxic (115.11 μg/mL) effect. The in vivo anxiolytic activity was studied by an elevated plus maze test, whereas the antidepressant activity was examined by a tail suspension test and forced swimming test. During the anxiolytic evaluation, MELHS exhibited a significant dose-dependent reduction of anxiety, in which the 400 mg/kg dose of the extract showed 78.77 ± 4.42% time spent in the open arm in the elevated plus maze test. In addition, MELHS demonstrated dose-dependent and significant activities in the tail suspension test and forced swimming test, whereas the 400 mg/kg dose of the extract showed 87.67 ± 6.40% and 83.33 ± 6.39% inhibition of immobile time, respectively. Therefore, the current study suggests that L. hyalina could be a potential source of anti-oxidative, cytotoxic, thrombolytic, anxiolytic, and antidepressant agents. Further study is needed to determine the mechanism behind the bioactivities.

In this study, we investigated the possible antidepressant-like effect ofI. paraguariensisin rats. Rats were treated for four weeks with an aqueous extract ofI. paraguariensisin drinking water, following the traditional preparation of this beverage. After the period of treatment, behavioral (elevated plus-maze, open field test, and forced swimming test) and biochemical parameters (lipid peroxidation assay, thiol content, vitamin C levels, and monoamine oxidase activity) were evaluated. Animals were also analyzed on forced swimming test after 24 hours ofI. paraguariensisintake. An additional group was injected with selegiline 24 hours and 30 minutes before forced swimming test as positive control. HPLC analysis revealed the profile ofI. paraguariensisextract.I. paraguariensisreduced the immobility time on forced swimming test without significant changes in locomotor activity in the open field test. Any anxiolytic/anxiogenic effect ofI. paraguariensiswas observed in rats through the elevated plus-maze test. The antidepressant-like effect ofI. paraguariensiswas not accompanied by inhibitory effect on monoamine oxidase activity. There were no significant alterations on lipid peroxidation, thiol content, and vitamin C levels among the groups. In conclusion, aqueous extract ofI. paraguariensisdecreases the time of immobility in rats suggesting an antidepressant-like effect.

Now-a-days, the use of natural products has increased its popularity day by day all over the world. One of the most effective therapeutic medicinal plants is Bacopa monnieri. In the current study, the methanolic distillate of B. monnieri was designed for an antidepressant in mice models. B. monnieri was evaluated for anti-depressant venture in the forced swimming test (FST), tail suspension test (TST) and elevated plus maze test. In force swimming test, imipramine (30 mg/kg) used as a standard drug and in TST as well as elevated plus maze test, diazepam (10 mg/kg) used as a standard and the plant extract (100 mg/kg and 200 mg/kg) was administered as test group and the control group was given deionized water. In this test, the test extracts (100 mg/kg and 200 mg/kg) compare to both control and standard group. The higher dose (200 mg/kg) represented a more significant effect than a dose of 100 mg/kg. In comparison to the standard and control, at dose 200 mg/kg represented a more significant effect at p<0.05 among three of the test.

Aims: Benign prostatic hyperplasia (BPH) is common urological disease, is characterized by lower urinary tract syndrome, usually associated with sexual dysfunctions. The aim of present study is to investigate the effects of terazosin, silodosin and alfuzosin which are the main treatment options for BPH on depression and anxiety to understand whether these drugs may be effective in BPH caused mood disorders. Study Design: All the drugs were given intraperitoneally (i.p.) in a volume of 0.1 ml per 10 g body weight of mice. Drugs were given 30 min before the experiment. We investigated the effects of terazosin, silodosin and alfuzosin on depression and anxiety, in mice. Place and Duration of Study: Sample: Department of Pharmacology and Department of Urology, Sakarya University, Animal Research Center, between June 2019 and September 2020. Methodology: Here, we examined the effects of terazosin (0.5, 1, 2 mg/kg), silodosin silodosin (1, 3, 10 mg/kg) and alfuzosin (3, 6 and 9 mg/kg) on depression and anxiety by using forced swimming test and elevated plus maze test, respectively, in mice (n:96). Additionally, the locomotor activity was evaluated by open field test. Results: All doses of terazosin, alfuzosin and silodosin significantly increased immobility time, compared to saline group. Silodosin and alfuzosin prolonged the time spent in open arms but terazosin decreased the time spent in open arms compared to saline group. Terazosin, silodosin (1 and 3 mg/kg) and alfuzosin (3 and 6 mg/kg) did not have any effect on the number of entries into the open arms while silodosin (10 mg/kg) and alfuzosin (9 mg/kg) increased the number of entries into open arms. Conclusion: We found that silodosin and alfuzosin had antidepressant and anxiolytic-like effects, while terazosin had depressant and anxiogenic effects. Patients with BPH who need antidepressant and anxiolytic treatment can be treated with a single drug instead of multiple medications.
