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.

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.

Objective: To evaluate the possible antidepressant effects of alpha-terpineol in rodents. Material and Methods: Depression levels were analyzed by comparing the total immobility time presented by the animals of the experimental groups in the test session, using the Forced Swimming Test and the Tail Suspension Test. The parameters of locomotion (central, peripheral and total) and motor coordination were evaluated in the Open Field Test and in the Rota Rod Test, respectively. In the second stage, the involvement of the noradrenergic system in the antidepressant action of alpha-terpineol in Forced Swimming Test was investigated. Results and Discussion: After performing the experimental tests, it was observed that the animals that received alpha-terpineol had reduced immobility time in Forced Swimming Test and Tail Suspension Test, compared to the other groups. In the Open Field Test and Rota-rod, the mice showed, respectively, good exploratory activity and motor coordination during the tests. In addition, the study of the Noradrenergic System proved to be a promising mechanism used during its antidepressant action. Conclusion: In view of the results of the experimental tests, alpha-terpineol presented similar responses to those found in other monoterpenes investigated in the literature. Thus, it is shown as a promising antidepressant to be used clinically in humans, with less side effects and low production cost.

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.

Abstract Objective: To explore the efficacy and possible mechanism of Danzhi Xiaoyao Powder in the treatment of scratching behavior worsened by psychological factors. Methods: Male BALB/c mice were divided into control group (CON group), chronic WAS group(WAS group) and chronic WAS + Danzhi Xiaoyao Powder group(DZX group). All mice excluded control group were exposed to 1 h water avoidance stress (WAS) for ten consecutive days. DZX group were given Danzhi Xiaoyao Powder solution by intragastric administration every day, and the other two groups were given the same amount of saline. Twenty-four hours after the last stress session, the mice were injected into the back of the neck with a condensation product of N-methyl-p- methoxyphenethylamine with formaldehyde (compound 48/80), and their scratching behavior was then observed for 120 min. The scratching number was recorded, th histamine levels in the plasma were examined, and the behavioral changes of depression in mice before and after treatment were observed by open field test and forced swimming test. Results: The scratching number was significantly higher in the WAS group than in the DZX group, which still higher than in the CON group. The peak histamine in the plasma after the compound 48/80 injection were also significantly higher in the WAS group in comparison to the DZX group. In terms of depression behavior, the number of standing in the DZX group was more than that in the WAS group and less than that in the CON group, and the immobility time in the forced swimming test was less than that in the WAS group and more than that in the CON group. Conclusion: Danzhi Xiaoyao Powder can relieve the scratching behavior of mice under the influence of WAS, and its possible mechanism is to control the release of histamine and improve the depressive state of mice.

Background and Aim. Depression is a social problem with high economic burden in the society. Finding an effective agent with high efficacy and few side effects is therefore needed. Involvement of neuroimmune response as well as nitric oxide (NO) has been determined in the pathophysiology of depression. Limonene is a terpene with various pharmacological properties. Thus, we aimed to evaluate antidepressant-like effect of limonene on a mouse model of maternal separation (MS) focusing on neuroinflammation and NO level in the hippocampus. Methods. Mice were randomly divided into experimental groups as follows: the control group received normal saline and MS groups received normal saline, limonene (10 and 20 mg/kg), L-NAME (10 mg/kg), L-arginine (L-arg) (75 mg/kg), limonene (10 mg/kg) plus L-NAME, and limonene (20 mg/kg) plus L-arg. Behavioral tests including the forced swimming test (FST), open field test (OFT), and splash test were performed. Finally, serum and hippocampal nitrite levels as well as the expression of inflammatory genes (IL-1β and TNF-α) in the hippocampus were measured. Results. We showed that MS caused depressive-like behavior. Treatment of MS mice with limonene reduced the duration of immobility time in FST and increases the grooming activity time in the splash test. Limonene also reduces serum and brain nitrite levels and reduces the expression of IL-1β and TNF-α in the hippocampus. We found that L-NAME potentiated the effects of a subeffective dose of limonene. Conclusion. We concluded that the antidepressant-like effects of limonene are probably mediated through inhibition of neuroinflammation and attenuation of nitrite levels in the hippocampus.

Background: The homeopathic complex Homeo-Pax® has been used as an antidepressant and anxiolytic homeopathic medicine available in Brazil. It is a complex mixture prepared with Aconitum nap. 6cH, Aurum met. 6cH, Phosphorus 6cH, Argentum nitricum 6cH, Arsenicum alb. 6cH, and Valeriana officinalis 3cH. Aims: This study had evaluated the behavior in rats after treatment with Homeo-Pax® in pre-clinical models of depression and anxiety. Mathods: Elevated Plus Maze Test (EPM), Forced Swimming Test (FST), Open Field Test (OFT) and the Rota Rod Test (RRT) behavior assays were used to confirm its activity. In the EPM, the animals treated with Homeo-pax® on the 1st day and until the 20th day of treatment remained longer in the open arms of the maze than on 30th day. This result was statistically significant compared with the control group (p < 0.05). In the FST, the treatment with Homeo-pax® (0.5 ml, p.o) increased the swimming time, compared to the control group. This effect was dependent on treatment time, resulting in a similar effect to that presented by amfepramone (10 mg/kg, p.o). In the OFT, crossing by the animals was significantly increased by the treatment with amfepramone (10mg/kg, p.o), and also with the 30-day treatment with Homeo-pax®. In the RRT, the 30-day treatment with Homeo-pax® (0.5 ml, p.o) did not affect the animals’ motor coordination, compared with the control group, which presented the same behavior. Conclusion: Based on the results obtained, it can be suggested that the homeopathic complex Homeo-pax® has anxiolytic and antidepressant properties without affecting motor coordination capacity.

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.

Growing evidence indicates that chronic neuropathic pain is frequently accompanied by an array of psychiatric diseases, such as depression and anxiety. Electroacupuncture (EA), as one therapy of traditional Chinese medicine, has displayed potent antidepressant-like effects in numerous clinical studies. The present study was designed to examine the possible effects of EA on the depressive and anxiety disorders induced by neuropathic pain. A classic rat model of neuropathic pain was produced by chronic constriction injury (CCI) of the sciatic nerve. EA was performed on acupoints “Bai-Hui” (GV20) and unilateral “Yang-Ling-Quan” (GB34). The antidepressive and anxiolytic effects of EA treatment were analyzed using the forced swimming test (FST) and the elevated plus maze (EPM) test, respectively. CCI resulted in remarkable depression- and anxiety-like behaviors, whereas the chronic EA treatment significantly improved the behavioral deficits of CCI rats. Moreover, the phosphorylation level of the NMDA receptor type 1 (NR1) subunit was decreased in the hippocampus of CCI rats. Intriguingly, continuous EA treatment effectively blocked this decrease in the levels of pNR1. These results suggested that EA has antidepressive and anxiolytic effects on rats with neuropathic pain and that this might be associated with restoring the phosphorylation of NR1 in the hippocampus.
