Introduction: Anxiety disorders being ranked at sixth position in the global burden of diseases is affecting over 250 million people. Curcumin, an active phytochemical flavonoid, has shown to induce the monoamine neurotransmitter serotonin, a prominent neurotransmitter in modulating the brain state in anxiety. Also, evidences reveal that zinc plays a key role in human neurodevelopment and supplementation of zinc enhanced the efficacy of antidepressant drugs through synergistic action. Aim: To evaluate the synergistic antianxiety effect of curcumin and zinc on acute and chronic models of anxiety in male swiss albino mice. Materials and Methods: A total of 36 male Swiss Albino mice, weighing 20-30 g, were randomly grouped to six groups, such that each group consisted of six mice. Group 1 served as control. Group 2 received standard drug diazepam 3 mg/kg Intra Peritoneal (IP). Group 3 and 4 received curcumin at doses of 5 and 10 mg/kg, respectively. Group 5 and 6 received curcumin at doses 5 and 10 mg/kg per oral (p.o) along with zinc chloride 10 mg/kg IP, respectively. The anxiolytic effect was studied in two validated models of anxiety such as Elevated Plus Maze (EPM) test and light/dark box test. Each animal was tested initially in the EPM followed by light/dark box test after administration of drug/vehicle one hour prior to the experiment in acute study. Following a washout period of one week, the animals were utilised for the study of chronic anxiolytic effect wherein the drugs were administered once daily for 14 days. Results: Curcumin at doses of 5 mg/kg and 10 mg/kg with zinc chloride 10 mg/kg showed a significant increase in the number of entries and time spent in open arm in EPM both on acute and chronic administration (p<0.001). In the light/dark box test, curcumin at doses of 5 mg/kg and 10 mg/kg when given along with zinc chloride 10 mg/kg significantly increased the number of entries and time spent in the light compartment both in acute and chronic models (p<0.001). Conclusion: The anxiolytic effect of synergistic action of curcumin and zinc was efficacious in both acute and chronic models of anxiety in mice.

Background: Depression and hypertension are common morbidities which are seen in elderly and also one leads to the other. Present antidepressant drugs are known for its side effects and there is a necessary for newer drugs with lesser adverse effects. Telmisartan being a widely used antihypertensive drug and with multiple additional properties like peroxisome proliferator-activated receptor gamma activity along with blunting of renin-angiotensin-aldosterone system can be a potential drug for depression. Hence this study is aimed to evaluate the antidepressant activity of angiotensin receptor blocker telmisartan in animal models.Methods: As per protocol submitted to ethics committee, 24 male albino mice weighing between 20-30grams of either sex were selected and divided into 4 groups consisting of 6 each. They were housed in cages with food and water ad libitum. Animals were kept in ambient temperature and humidity, with a 12-hour light and 12-hour dark cycle.  Group 1 and group 2 were administered distilled water and fluoxetine 10 mg/kg respectively only on day 15, whereas group 3 and group 4 received telmisartan per orally 1 mg/kg and 2 mg/kg respectively for 15 days once daily. All animals were tested on day 15 using tail suspension test for antidepressant effect.Results: There was significant reduction in the immobility time in telmisartan group when compared to the control group and this time was comparable with the immobility time of standard drug fluoxetine. Decrease in immobility time was found to statistically significant by using one-way ANOVA followed by Bonferroni post hoc test.Conclusions: As evident from our study, telmisartan can be a newer target for antidepressant effect.

Background: Hormones play a vital role in initiating and maintenance of male reproductive or testicular function which includes the production of androgens and spermatozoa. Testosterone is essential for the initiation and maintenance of spermatogenesis. FSH is responsible for the stimulation of spermatogenesis. Semen analysis and hormone evaluation are essential parameters in the diagnosis of infertility in males. Objective: The aim of the present study is to evaluate the effect of sorafenib on FSH and intratesticular testosterone levels in male Swiss albino mice. Materials and Methods: The animals were segregated into control, positive control, and treatment groups (n=6). Treatment group received 25, 50 and 100 mg/kg body weight of sorafenib orally for seven consecutive days at intervals of 24 hours between two administrations. Positive control group received 100 mg/kg body weight of imatinib. The animals were sacrificed at the end of 1st, 2nd, 4th, 5th, 7th and 10th week after the last exposure to sorafenib. Results: The intratesticular testosterone level was significantly (P<0.05) reduced in treated groups and severe effect was observed on week 4th and 5th weeks. FSH level was increased significantly (P<0.05) in sorafenib treated groups of mice. Conclusion: The administration of sorafenib does affect testosterone and FSH level significantly, but this effect is reversible once the drug is withdrawn. This finding may help the clinicians to plan and address the fertility-related issues in young patients of reproductive age who are being treated with sorafenib for advanced renal cell carcinoma, hepatocellular carcinoma and differentiated thyroid carcinoma.

AbstractLiver plays a central role in the metabolism of drugs. Drug clearance and transformation exposes liver to toxic injury. Antitubercular drugs have been found to be hepatotoxic and potentially lead to drug-induced liver injury. Isoniazid is one of the most hepatotoxic first line antitubercular drugs. Conventional drugs used in the treatment of liver disease are often inadequate and a search for supplementation or alternative drugs for the treatment of hepatic damage is indispensible. Therefore our study aims to investigate the hepatoprotective potential of Vernonia Amygdalina Del (bitter leaf) extract against Isoniazid-induced liver injury in Swiss Albino Mice. Treatment of Mice orally with Vernonia Amygdalina Del extract at dose of 250mg/kg and 375 mg/kg significantly lowered (P<0.05) the serum level of liver enzymes in Isoniazid pretreated mice. The hepatoptotective activity of the extract found to be comparable with the standard drug, Silymarin (100 mg/kg, P.o.). Moreover, treatment with the extract significantly alleviated Isoniazid induced hepatic injury as supported by the photomicrographs of liver section of mice. The data shows aqueous Vernonia Amygdalina Del extract has a very promising hepatoprotective potential against isoniazid-induced liver injury.

To evaluate the effect of Aqueous extract of Terminalia belliricafruit pulp (AETB) on learning by Hebb William maze model in mice with acute alcohol consumption.Swiss albino mice (n=48) of either sex weighing 20-30g will be divided into eight groups of six mice each. Drugs were given orally after 12 hours of fasting. Group I mice received 10ml/kg of Normal Saline, Group II mice received Piracetam 200mg/kg, Group III received AETB 36mg/kg, Group IV received ethanol 1.5g/kg orally, Group V received ethanol(1.5g/kg )+ piracetam (200mg/kg), Group VI mice received ethanol(1.5g/kg) +AETB(9mg/kg), Group VII mice received ethanol(1.5g/kg) +AETB (18mg/kg), Group VIII mice received ethanol(1.5g/kg) +AETB(36mg/kg). Time taken by the animal to reach the reward chamber from the start chamber (TRC) in Hebb-William maze was used as a parameterto evaluate the learning.Acute alcohol administration showed increase in TRC. Whereas, acute administration of Aqueous extracts of Terminalia belliricafruit pulp showed a decrease in TRC when compared to the control group. The TRC values for the groups that were administered AETB along with acute alcohol administration showed decrease in TRC values compared to the negative control.Current study showed acute alcohol administration caused impairment of thelearning ability in mice. Whereas, acute administration of Aqueous extracts of Terminalia belliricafruit pulp (AETB)caused enhancement of learning. Pre-treatment with AETB before acute alcohol administration indicated protective action of AETB on alcohol affected learning in mice.

Wound healing is a complex physiological process consisting of four phases: coagulation, inflammation, proliferation and migration, and remodeling, each with distinct characteristics. Studies have suggested that mangosteen pericarp extract (MPE) may accelerate wound healing. However, the mechanism has not been fully understood. This study aims to evaluate the effect of MPE cream in various concentrations in acute wound healing of albino mice, both histologically and macroscopically. Thirty-two healthy female Swiss albino mice, aged 6-9 weeks, weight 20-30 g, were included in this study. The samples were randomly divided into eight groups each consisting of 4 mice. The first four groups were treated with MPE cream 5%, 10%, and 20%, and no medication (control group), respectively, and were sacrificed after three days. The other four groups received the same application and were sacrificed after 8 days. Wound bed diameter was measured and biopsy from the skin lesion was performed for histopathologic examination. Mann-Whitney test was used to analyze the diameter of the wound bed and histopathological findings of granulation tissue formation, reepithelialization, and inflammation, with P<0.05 considered as significant. MPE cream significantly improved wound healing by increasing granulation tissue formation, and reepithelialization. In addition, MPE cream application was also shown to decrease the number of inflammatory cells, particularly in 5% and 10% concentrations, both in the 3-day and 8-day groups. MPE cream application can accelerate wound healing and thus can be used in acute wound treatment.

The purpose of this study was to examine the effects of daily exercise of varying duration on the body composition, weight, and feed intake of mature Swiss albino mice. Fifty-four male mice were equally divided into a control group and five exercise groups (n = 9) performing 20, 40, 60, 120, and 240 min of daily exercise on a treadmill (7.2 m/min). Feed intake and body weight were measured weekly for 10 wk. At the completion of the study the mice were killed and the animal carcasses were chemically analyzed for fat, dry matter, and protein content. The results of this study demonstrate no differences in the body weight among groups (P less than 0.97) with all groups gaining 4.5–5.8 g during the 10-wk period. However, fat content decreased significantly from 15.7% in the control to 12.0% in the 120- and 240-min exercise groups (P less than 0.05). In contrast, protein content showed an insignificant rising trend from 13.0 to 14.6% with increasing duration of exercise. Feed intake showed a nonsignificant drop during the 20-min exercise treatment and remained unchanged among groups. These data show a slight but variable appetite-suppressing effect of light exercise in mice accompanied by favorable body composition changes even in the absence of differences in body weight. These findings suggest the mouse to be an acceptable experimental model for body composition and exercise studies.

Objective: Fertility control is an issue of global public health. Many of the contraceptives available today have one or the other side effects. Many plants and plant products are suggested as contraceptives in folk and traditional systems of medicine. However, that are least exploited in this regard. In the present investigation, root powder of Ruellia tuberosa was studied for its effect on male reproduction in mice.Methods: The Swiss albino mice, Mus musculus of age three months were grouped into four, i)control group, fed on standard pellet, ii)experimental groups I and II received root powder of Ruellia tuberosa 50 mg/mouse/days for 15 d and 30 d respectively in the pellets, iii)positive control groups I and II received cotton seed oil 25 µl/mouse/day for 15 and 30 d and iv)recovery group received Ruellia tuberosa (50 mg/mouse/days) containing pellets for 15 d and later standard pellet for 15 d. Cauda epididymis sperm suspension was analyzed for sperm count, motility and viability.Results: There was a highly significant decrease in sperm count, motility and viability (p<0.001) in experimental groups I and II and positive control groups I and II. The sperm count was reduced to 19.24±1.74 million/ml and 15.97±5.61 million/ml as compared to sperm count in control group (55.12±4.63 million/ml) in experimental groups. Partial reversal of the effect was noticed in a recovery group.Conclusion: The results suggest that Ruellia tuberosa can be a potent member of reversible oral male contraceptives.

Glyphosate (N-(phosphonomethyl) glycine,C3H8NO5P), a herbicide, used to control unwanted annual and perennial plants all over the world. Nevertheless, occupational and environmental exposure to pesticides can pose a threat to nontarget species including human beings. Therefore, in the present study, genotoxic effects of the herbicide glyphosate were analyzed by measuring chromosomal aberrations (CAs) and micronuclei (MN) in bone marrow cells of Swiss albino mice. A single dose of glyphosate was given intraperitoneally (i.p) to the animals at a concentration of 25 and 50 mg/kg b.wt. Animals of positive control group were injectedi.p. benzo(a)pyrene (100 mg/kg b.wt., once only), whereas, animals of control (vehicle) group were injectedi.p. dimethyl sulfoxide (0.2mL). Animals from all the groups were sacrificed at sampling times of 24, 48, and 72 hours and their bone marrow was analyzed for cytogenetic and chromosomal damage. Glyphosate treatment significantly increases CAs and MN induction at both treatments and time compared with the vehicle control (P<.05). The cytotoxic effects of glyphosate were also evident, as observed by significant decrease in mitotic index (MI). The present results indicate that glyphosate is clastogenic and cytotoxic to mouse bone marrow.

The study reports antidotal efficacy of three HNK [ bis quaternary 2-(hydroxyimino)-N-(pyridin-3yl) acetamide derivatives] and pralidoxime (2-PAM), against soman and tabun poisoning in Swiss albino mice. Protection index (PI) was determined (treatment doses: HNK oximes, ×0.20 of their median lethal dose (LD50) and 2-PAM, 30 mg/kg, intramuscularly (im)) together with atropine (10 mg/kg, intraperitoneally). Probit log doses with difference of 0.301 log of LD50 of the nerve agents administered and inhibition of acetylcholinesterase (AChE) activity by 50% (IC50) was calculated at optimized time in brain and serum. Using various doses of tabun and soman (subcutaneously (sc)), in multiples of their IC50, AChE reactivation ability of the oximes was studied. Besides, acute toxicity (0.8× LD50, im, 24 h postexposure) of HNK-102 and 2-PAM was also compared by determining biochemical, hematological variables and making histopathological observations. Protection offered by HNK-102 against tabun poisoning was found to be four times higher compared to 2-PAM. However, nearly equal protection was noted with all the four oximes against soman poisoning. HNK-102 reactivated brain AChE activity by 1.5 times more than 2-PAM at IC50 dose of soman and tabun. Acute toxicity studies of HNK-102 and 2-PAM showed sporadic changes in urea, uric acid, aspartate aminotransferase, and so on compared to control group, however, not supported by histopathological investigations. The present investigation showed superiority of newly synthesized HNK-102 oxime over standard 2-PAM, as a better antidote, against acute poisoning of tabun (4.00 times) and soman (1.04 times), in Swiss albino mice.
