Antileishmaniasis effects of monoherbal skin ointment made from bark and leaf of Holoptelea integrifolia (Roxb.) Planch. in patients of cutaneous leishmaniasis.

Prevalence of parasitic skin diseases, cutaneous leishmaniasis is very frequent in Pakistan, especially in Baluchistan where occurrence of phelbotomine sand flies (vector of protozoan parasite of genus Leishmania) is very common. This study was conducted to assess the antileishmaniasis activity of Intericutol plus ointment (2% and 3%) made with ethanolic extract of bark and leaves of Holoptelea integrifolia (Roxb.)Planch. The antileishmaniasis effect was observed by applying the ointments on the lesions of leishmaniasis patients. 150 patients were included in the study that had single and multiple painful wet and dry ulcerative lesions on the exposed area of the body. The patients were divided into two groups of 75 patients each, applying 2% and 3% ointment respectively for 28 days. Dose of 10gm/week was applied topically on wounds. Excellent antileishmaniasis effect was observed with significant quick healing properties in the patients receiving 3% Intericutol plus ointment as compare to 2% showing 89% and 81% cure (p=0.02) respectively. It can be concluded that ointment made from medicinal plant proved to be very effective in treating cutaneous Leishmaniasis.

Pharmacological effects of Raphanus caudatus in inflammation and hematopoitic system: an in vitro and in vivo investigation.

The pods of Radish are known as Raphanus caudatus that belongs to the family Brassicaceae. They are commonly known as Mungra or Sungra in Pakistan, while the common English name for this species is Rat-tailed radish. This variety of radish is unique and less tested for pharmacological as well as toxicological potential. In the current research, the ethanol extract of pods was assessed for anti-inflammatory potential in vitro and in vivo. Furthermore the effect of plant on hematological parameters was also investigated. For in vitro study, luminol-enhanced chemiluminescence method was used while in vivo study was carried out via Acetic acid- induced Paw Edema Test in wistar rats. The extract of Raphanus caudatus indicated significant anti-inflammatory effects regarding in vitro assay. Administered tested doses (250mg, 500mg and 1000mg/kg) of plant extract showed significant reduction in rat's paw but highest in vivo anti-inflammatory effect was observed at the dose of 1000mg/kg. Moreover, in the case of hematological study, noticeable elevation of white blood cell count was observed at 500 and 1000 mg/kg. However the number of platelets was reduced in dose dependent manner.

Anxiolytic, antidepressant and inhibitory effect on MAO isoenzymes by Bougainvillea glabra flower extract in rats.

Main aim of current study was to determine the anxiolytic and antidepressant potential of Bougainvillea glabra Extract (BVE). The effects were investigated by using Open-Field-Test (OFT), Light-and-Dark Model (LD), Hole-Board (HB) and Forced-Swimming-Test (FST). Different doses for BVE were given to Wistar-Rats and compared with Control and Diazepam. Data has been collected by simple observations of animal behaviors in mentioned models. Collected data was analyzed by SPSS-22 version. In OFT (number of squares travelled), significant differences noted between Control and BV100mg/kg (p=0.001), Diazepam and BV100mg/kg (p=0.0001), Diazepam and BV200mg/kg (p=0.015), Diazepam and BV300 mg/kg (p=0.002). In LD-Test, significant differences were noted between Control and BV100mg/kg, BV200mg/kg and BV300mg/kg (p=0.0001), Diazepam and BV100mg/kg, 200mg/kg (p=0.0001), Diazepam and BV300mg/kg (p=0.028). In HB-Test by head dips, significant differences noted between control group and BV100mg/kg and 200mg/kg (p=0.0001), Control group and BV300mg/kg (p=0.005). For number of head dips, significant differences noted between Diazepam and BV100mg/kg, 200mg/kg and 300mg/kg (p=0.0001). In FST, significant differences were observed between Control group and BV100mg/kg, BV200mg/kg and BV300mg/kg (p=0.0001), Fluoxetine and BV100mg/kg, BV200mg/kg and BV300mg/kg (p=0.0001). It is observed that MAO-A and MAO-B are inhibited by BVE. Study demonstrates that BV flowers have anxiolytic and antidepressant activities.

A comparative neurobehavioral study of sesame oil and fish oil on experimental animals.

Natural oils are enriched with polyunsaturated fatty acids (PUFAs) which are important for our health. Recent experimental data explained that PUFAs might have a beneficial effect on various brain functions such as anxiety, dementia, epileptic seizures, depression or bipolar and other neurobehavioral diseases. The objective of the current research work was to evaluate the effect of sesame oil, fish oil and mixture of both oils (1:1) on neurobehavioral changes and cognition. For this purpose shark fish oil and sesame oil were extracted out and there poly unsaturated and saturated fatty acids were analyzed by using GCFID that exposed the presence of different PUFs in shark fish oil, sesame oil and mixture of both oils. Neurobehavioral changes were seen after 5ml/kg/day sesame oil, 5ml/kg/day shark fish oil and 1:1 combination of both oil 5ml/kg/day administration on open field, cage crossing, light and dark, stationary rod, forced swimming induced depression test and water maze test. Our GCFID results showed sesame and fish oil enriched with higher amount of PUFs and showed significant anxiolytic and antidepressant like effect after 30 days of treatment (P<0.05) however combination of these both oils exhibited greater efficacy (P<0.01) in reducing anxiety and depression as imipramine standard drug. Results showed that combination of both oils (sesame oil and fish oil) could be a better option to treat neurobehavioral problems as compared to alone.

Neuro-pharmacological evaluation of anticonvulsant and neuroprotective activity of Cocculus laurifolius leaves in wistar rats.

The aim of the study was to evaluate the anticonvulsant and neuroprotective activity of Cocculus laurifolius D.C leaves in albino wistar rats against strychnine induced convulsions. Initially the extract was investigated for acute oral toxicity testing in order to examine any signs of toxicity and mortality. For anticonvulsant activity, the ethanolic extract was evaluated at doses 200 and 400 mg/kg, p.o. against strychnine induced convulsions model, at 1, 7, 15 and 30th day of treatment. Meanwhile, the neuroprotective effect of the extract was investigated via histopathological assessment. Cocculus laurifolius (200 and 400 mg/kg, p.o.) exhibited anticonvulsant activity as indicated by significant delay in the onset of convulsions and time to death after strychnine induced convulsions. Similarly, significant reduction in the duration of convulsions and percentage of mortality was observed by ethanolic extract (200 and 400 mg/kg p.o.) at 1, 7, 15 and 30th day of test sessions. Furthermore, Cocculus laurifolius leaves (200 and 400 mg/kg p.o.) also exhibited neuroprotective effect with considerable preserved neuronal structures and significant decrease in neuronal apoptosis, in comparison with control. The results obtained from the present study indicate that ethanolic extract of Cocculus laurifolius leaves possess potential anticonvulsant and neuroprotective effect against strychnine induced convulsions. Therefore, it can be concluded that Cocculus laurifolius leaves may be a valuable in management of epilepsy, however further studies are required on large number of animals to confirm these findings.

Evaluation of pharmacological and toxic effects of ethanolic extract of radish pods in albino rabbits: A biochemical and histopathological study.

Radish pods are known as vegetable eaten as a part of diet. Though the pharmacologic potential of radish has been well known but there are fewer reports regarding pharmacological and toxic effects of radish pods. On account of this reason, the current study was aimed to evaluate the pharmacological and toxic effects of ethanol extract of Raphanus caudatus (radish pods) in rabbits after 60 days of administration. The plant extract was administered in 250, 500 and 1000mg/kg doses and effect was observed on hepatic, renal, cardiac and lipid profile. The extract was found to be hepatoprotective, nephroprotective and cardioprotective. Also it showed hypocholestrolemic potential at 1000 mg/kg. However at higher doses the extract presented chronic gastritis. Conversely, no indication of histological alterations was seen in other vital organs such as liver, kidneys, heart. Thus there is critical requirement to identify toxic constituent/s inducing gastritis so that safety profile of the plant can be established for effective therapeutic use.

Hibiscus rosa sinensis mediate anxiolytic effect via modulation of ionotropic GABA-A receptors: possible mechanism of action.

The current study was designed with the aim to investigate anti-anxiety potential of Hibiscus rosa sinensis roots and its possible mechanism of action. For this purpose hole board test, elevated plus maze test and light/dark exploration test were employed. The ethanol extract of plant was administered orally at two different doses i.e. 100 and 500 mg/kg for consecutive 14 days. The results of present investigation indicate that plant extract significantly (p < 0.05) increased the number of head dips and rearings as compared to control on respective days of observation. The extract increased the time of permanence in open arms and the number of head dips in elevated plus maze. In light/dark test, our study indicate that Hibiscus rosa sinensis significantly (p < 0.05) increased the time spent in light compartment and number of entries as compared to control. In addition the anxiolytic effects of HRS at highest tested dose were blocked by flumazenil, a GABA-A receptor antagonist that indicate that Hibiscus rosa sinensis potentiated the GABAergic actions. The results propose that the ethanol extract of Hibiscus rosa sinensis has prospective anxiolytic effect in mice via inhibition of ionotropic GABA receptors, using different behavioral paradigms.

The Radish, Raphanus sativus L. Var. caudatus reduces anxiety-like behavior in mice.

Inclusion of vegetables in the diet not only provides dietary fiber, vitamins, minerals, trace elements but also significantly reduces the risk of several diseases. Raphanus sativus L. Var. caudatus belongs to the family Brassicaceae are pods of Radish, and are commonly known as Mungra or Sungra in Pakistan and India. The English name for this species is Rat-tailed radish. This variety of radish is unique, less familiar to the population, and not commonly used as a food source. Furthermore there have been very few studies that report on the potential antioxidant and anti-cancer capabilities of this radish. The present study was designed to evaluate anxiolytic potential of Raphanus caudatus in mice using different behavioral paradigms. The ethanol extract of the plant was evaluated at three different doses i.e. 250, 500 and 1000 mg/kg. The extract at doses of 250 and 500 mg/kg produced a significant (p < 0.05) reduction of anxiety-like behavior in mice and results are comparable to standard anxiolytic drug diazepam.

The aim of this study was to evaluate antiviral activity of chloroformic leaves extracts of three plants: Azadirachta indica, Moringa oleifera and Morus alba against Foot and Mouth disease virus using MTT assay (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide). Antiviral and cytotoxic activity of each extract was evaluated as cell survival percentage and results were expressed as Means ± S.D. The concentrations which resulted in cell survival percentages of greater than 50% are considered to be effective antiviral concentrations. From the tested plant extracts, Moringa oleifera showed potent antiviral activity (p<0.05) while Azadirachta indica showed significant antiviral activity in the range of 1-50µ/ml & 12-100µ/ml respectively. In contrast no antiviral activity was observed by Morus alba as all the tested concentration resulted in significant reduction (p<0.05) in cell survival percentage.

BEHAVIORAL EVIDENCE OF ANTIDEPRESSANT-LIKE ACTIVITY OF RAPHANUS SATIVUS L. VAR. CAUDATUS IN MICE.

BACKGROUND: Currently-available antidepressant agents produce various adverse effects, and are expensive. At present, various plants are being evaluated for their possible role against numerous diseases, and no doubt, the role of traditional and complementary medicines in the development of effective therapy is incredible. The present study was designed to evaluate antidepressant-like activity of Raphanus sativus L. Var. caudatus at different doses in mice. MATERIALS AND METHODS: Antidepressant potential of ethanolic extract of Raphanus caudatus L. was evaluated at three different doses 250 mg/kg, 500 mg/kg and 1000 mg/kg by using forced swim test and tail suspension test on albino male mice. The results were compared with control and standard mice groups administered with normal saline and Fluoxetine respectively. In both parameters immobility period was recorded two times during 60 days dosing. RESULTS: The ethanol extract at all three tested doses (250 mg/kg, 500 mg/kg and 1000 mg/kg) and standard fluoxetine demonstrated notable antidepressant-like activity (p<0.05) in both FST and TST paradigms. CONCLUSION: Our results clearly show that Raphanus caudatus ameliorate depression-like behavior in rodent model, and can be used to establish newer antidepressant approaches in future. However, mechanism-based studies are needed to establish the mechanistic action of Raphanus caudatus L.
