Plants are the priceless sources of bioactive natural compounds. Medicinal plants have been used since time immemorial in both developing and developed countries. Flemingia macrophylla (Willd.) is widely used as a hereditary medicines. The current study was designed to observe the analgesic, antidiarrheal and CNS depressant activities of methanol extract of the leaves of F. macrophylla (MEFM) and its petroleum ether (PEFM), dichloromethane (DFM), chloroform (CFM) and aqueous (AFM) fractions. The analgesic activities was assessed by acetic acid induced writhing method at doses 200- and 400- mg/kg body weight. The CNS-depressant effect was assayed by phenobarbitone sodium-induced sleeping time test. The anti-diarrheal activity of the extract was evaluated using castor oil-induced diarrhea in mice. The crude extract displayed significant peripheral analgesic activity at both test doses with 56.72- to 59.70-% inhibition of writhing responses, respectively. In CNS-depressant test, the extract revealed its activity in a dose dependent manner. In screening for antidiarrheal activity, the extract exhibited 20.83 and 41.67 % inhibition of defecation at 200- and 400-mg/kg bw, respectively whereas the standard loperamide (50 mg/kg bw) displayed 70.83 % inhibition of defecation.

Albizia lebbeck (Linn.) Benth. is a deciduous tree which is planted as ornamental and avenue tree almost all over Bangladesh. Leaves of the plant are used in ethnomedicine for the treatment of convulsion and CNS related disorder. This study was aimed to evaluate the neuropharmacological effects of the methanol extract of A. lebbeck leaves in Swiss albino mice. The locomotor effect of crude methanol extract of the plant was investigated by open field and hole cross tests while the anxiolytic activity was determined using elevated plus-maze (EPM) and light/dark box (LDB) tests. Furthermore, the sedative activity of the plant extract was assessed by sodium thiopental-induced sleeping time test. The results demonstrated that the methanol extract significantly (p < 0.001) reduced locomotion of the animals in both hole cross and open field tests in dose-dependent manner at 200-400 mg/kg b.w. In both EPM and LDB tests, the plant extract produced significant anxiolytic effect (p < 0.05) at the doses of 100-400 mg/kg b.w. In addition, it showed significant (p < 0.001) dose-dependent decrease in the onset of sleep and an increase in duration of sleep in sodium thiopental-induced sleeping time test. Preliminary phytochemical analyses of the plant extract revealed the presence of alkaloid, flavonoid, glycoside, saponin, tannin and resin. In acute toxicity test, the leaf extract did not exhibit any adverse effect in mice during 7 days treatment. The results of the present studies suggest that the crude methanol extract of A. lebbeck leaves possesses significant CNS depressant, anxiolytic and sedative properties and rationalize the traditional uses of the plant.Bangladesh Pharmaceutical Journal 21(2): 80-86, 2018

Pupalia lappacea Juss (Family: Amaranthaceae) is claimed to be useful in treatment of bone fracture, wounds, boils, cough, toothache, fever and malaria. The study was aimed to evaluate the 80% aqueous ethanolic extract of aerial parts of P. lappacea for antinociceptive and antipyretic activities to verify the traditional claim. The extract was orally administered at doses of 200, 400 and 600 mg/kg. The extract has significantly (P<0.01) reduced the nociception induced by acetic acid. The effect produced was in dose dependent manner. The antinociceptive effect was not reversed by pretreatment with naloxone in acetic acid induced writhing test. In hot plate method, the extract has significantly increased the latency time of jump. The naloxone has partially antagonised the antinociception of extract in hot plate test indicating P. lappacea has morphinomimetic properties. In the study of the CNS-depressant effects, the extract was found to produce significant reduction in head pokes and locomotion in mice by using hole board and locomotor activity test respectively. The extract has significantly reduced the rectal temperature in yeast induced pyrexia in rats at 600 mg/kg. The activity produced by extract was in dose dependent manner. Phytochemical investigation of ethanolic extract of P. lappacea revealed the presence of steroids and/or triterpenoids, flavonoids and phenolic compounds which may be responsible for antinociceptive and antipyretic activity of P. lappacea.DOI: http://dx.doi.org/10.3329/icpj.v2i2.13193 International Current Pharmaceutical Journal 2013, 2(2): 23-28

The methanol extract of the leaves of Canavalia virosa (Roxb.) W&A was investigated for the evaluation of analgesic, anti-diarrheal and CNS-depressant activities in Swiss albino mice. The analgesic activity was assessed by formalin-induced paw licking method, where the crude extract of C. virosa (400 mg/kg, b.w.) exhibited 41.46% reduction of licking response in mice as compared to 73.17% reduction exhibited by standard acetylsalicylic acid. In the castor oil-induced diarrhea in mice, the plant extract at the dose of 200 mg/kg, b.w., demonstrated 56% reduction of diarrheal feces in mice, while the standard loperamide revealed 76% reduction of diarrheal feces. The CNS-depressant activity of the plant extract was assessed through phenobarbitone-Na induced sleeping time test. The methanol extract of C. virosa and its different Kupchan fractions were also subjected to screen membrane stabilizing and cytotoxic activities using acetylsalicylic acid and vincristine sulphate as standard, respectively.

In Bangladesh, numerous tribal people of Chittagong Hill Tracts have been using different parts of Thysanolaena maxima Roxb. for many years. The present study was designed to investigate CNS depressant and analgesic activities of methanol extract of the aerial parts of the plant in mice models. CNS depressant activity of the crude extract (200 and 400 mg/kg) was evaluated using open field, hole cross and thiopental-induced sleeping time tests using diazepam as the standard. Analgesic activity was determined using acetic acid-induced writhing and hot plate tests using diclofenac sodium as the standard. The extract showed dose dependent suppression of locomotion in open field and hole cross tests and exerted sedative action in thiopental induced sleeping time. In the open field and the hole-cross tests, maximum CNS depressant activity was observed at 90 min after administration of extract and the standard drug. The extract significantly induced the onset of sleep and prolonged the sleeping time in thiopental induced sleeping test compared to the control group. The extract produced significant (p < 0.05) analgesic activity by inhibiting writhing by 41.89% and 60.81%, at doses of 200 and 400 mg/kg body weight, respectively, which was comparable to the inhibition of diclofenac sodium (73.64%). Additionally, in hot plate test, the extract exhibited a significant (p < 0.05) increase in pain threshold in a dose dependent manner. The findings of the study are encouraging and demands further investigation of other bioactivities with isolation of pure compounds. Dhaka Univ. J. Pharm. Sci. 20(2): 227-233, 2021 (December)

Syzygium cumini has been used in folk medicine to treat many diseases. To establish the potential medicinal value of leaves of S. cumini, the current study was carried out to assess the peripheral analgesic and anti-diarrheal activities in mice model. The crude methanol extract and its petroleum ether and chloroform soluble fraction were administered to the experimental mice at a dose of 200- and 400- mg/kg b.w. (denoted as CME1, CME2, PESF1, PESF2, CLSF1 and CLSF2 respectively) using acetic acid induced writhing method and castrol oil induced anti-diarrheal assay protocol. The extract and its Kupchan fractions exhibited significant (p < 0.001) reduction of writhing response in a dose dependent manner. In the acetic acid-induced writhing test, the activity decreased in the order diclofenac (75.33%) > PESF2 (70.33%) > CME2 (67.00%) > PESF1 (64.00%) > CLSF2 (61.33%) > CME1 (56.67%) >CLSF1 (48.67%). All the fractions significantly (p < 0.001) attenuated anti-diarrheal effect in a dose dependent manner with the highest activity observed by CME2 (47.73%) as compared to standard lopeiramide (54.55%). The results of our study, being reported for the first time, provide reasonable indication that the methanol extract of S. cumini leaf and its different fractions possess peripheral analgesic and antidiarrheal activities.

Hemigraphis hirta has been used by folk practitioners to alleviate symptoms of several diseases, although the pharmacological activities of this plant have not been thoroughly explored. The current study was designed to assess the anti-diarrheal and CNS depressant activities of H. hirta in mice model. For both assays, the experimental mice received the methanolic crude extract and its petroleum ether soluble fraction at dose of 200 and 400 mg/kg body weight which are denoted as CME 200, CME 400, PESF 200 and PESF 400, respectively. Both fractions remarkably attenuated castor oil-induced diarrheal effect in a dose-dependent manner and the results were comparable to standard loperamide (89.47%). Among all, PESF 400 exhibited statistically significant (p < 0.01) anti-diarrheal activity as demonstrated by 78.95% inhibition of defacetion. Compared to reference drug diazepam, all the tested samples considerably shortened the time for onset of sleep and prolonged the duration of phenobarbitoneinduced sleep in mice. The results of our present study, being reported for the first time, demonstrate that the methanol extract of leaves of H. hirta and its organic soluble partionates possesses significant anti-diarrheal and CNS depressant properties. However, this preliminary screening requires further detailed investigation to confirm these findings as well as to isolate and characterize the bioactive compounds.

The article deals with the history of the study and the current state of research of physiological and biochemical properties of the plant genus Sedum that are useful for human and has been used in folk medicine for many years. It was noticed that antioxidant properties of extracts from plants S. sarmentosum, S. sempervivoides, S. takesimense were caused by the presence of phenolic compounds. Methanol extract of plants S. takesimense exhibited strong scavenging activities against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radicals as well as significant inhibitory effects on lipid peroxidation and low density lipoprotein (LDL) oxidation induced by a metal ion Cu2+. Various immunomodulatory activities of various fractions of plants extracts (S. dendroideum, S. kamtschaticum, S. sarmentosum, S. telephium) are observed. It was shown that the ethanol extract of S. sarmentosum and it’s fractions suppressed specific antibody and cellular responses to ovalbumin in mice. The methanol extract of plants S. sarmentosum reduced the levels of anti-inflammatory markers, such as volume of exudates, number of polymorphonuclear leukocytes, suppressed nitric oxide synthesis in activated macrophages via suppressed induction of inducible nitric oxide synthase (iNOS). Polysaccharides fractions from plants S. telephium inducing productions of tumor necrosis factor alpha (TNF-α), increasing the intensity of phagocytosis in vitro and in vivo. Methanol extract from the whole part of S. kamtschaticum strongly inhibit PGE2 production from lipopolysaccharide-induced RAW 264.7 cells, a mouse macrophage cell line via modulating activity in gene expression of the enzyme cyclooxygenase-2 (COX-2). The methanol extract of plants S. sarmentosum and the major kaempferol glycosides from S. dendroideum have antinociceptive activity. It was noticed that anti-adipogenic activity of extracts from plants S. kamtschaticum were caused by inhibition of peroxisome-proliferator-activated receptor γ (PPARγ) expression and it’s dependent target genes, such as genes encoding adipocyte protein 2 (аР2), lipoprotein lipase (LPL), adiponectin and CD36. Polysaccharides fractions from S. telephium cause inhibition of cell adhesion of human fibroblast (MRC5) to laminin and fibronectin via interfere with integrin-mediated cell behaviour and they contributed to the role of polysaccharides in cell-matrix interaction. The methanol extract of plants S. sarmentosum exhibited a significant inhibitory activity in the chick embryo chorioallantoic membrane angiogenesis in a dose-dependent manner. The crude alkaloid fraction of S. sarmentosum caused a dose-dependent inhibition of cell proliferation on murine hepatoma cell line BNL CL.2 and human hepatoma cell line HepG2 without necrosis or apoptosis. Alkaloids from plants S. sarmentosum may improve survival of hepatoma patients via the inhibition of excessive growth of tumor cells. Plant’s juices have antiviral activity (S. sarmentosum, S. spurium, S. stahlii). Crude ethanol extract S. praealtum have spermicidal activity of the in mice and a relevant inhibitory effect of aqueous extract on human spermatozoa motility as well as an anti-fertilizing activity in rats. Hepatoprotective triterpenes, e.g., δ-amyrone, 3-epi-δ-amyrin, δ-amyrin and sarmentolin were isolated from S. sarmentosum. 2- and 2,6-substituted piperidine alkaloids (e.g., norsedamine, allosedridine, sedamine, allosedamine) are observed in plants S. acre, which in the presence of data on the use of pyridine and piperidine derivatives for treating neurodegenerative diseases (e.g., Alzheimer's disease), points on the promising research in this area. Taking into account that biologically active compounds are accumulated in the aboveground vegetative organs of plants of Sedum, the prospects of further study of the use of Sedum for the purposes of biotechnology and in the pharmaceutical industry becomes apparent. This work extends the existing views regarding the use of plants Sedum.

According to WHO, schizophrenia is a severe form of mental illness affecting about 7 per thousand of the adult popu-lation, mostly in the age group 15-35 years. Though the incidence is low (3-10,000), the prevalence is high due to chronicity. Schizophrenia is occurring in both developing and developed countries. The remission rate is higher in developing countries compared to the developed ones. There are some compelling factors that may influence the out-come of schizophrenia includes gender, employment, marital status, family support, illness myths, family burden, duration of untreated psychosis etc. In this review we have discussed the epidemiology, pathophysiology, diagnosis, treatment and finally the factors that influence the outcome of schizophrenia in developing and developed countries.Key Words: Schizophrenia, outcome, developing countries, antipsychotic agents.DOI: http://dx.doi.org/10.3329/icpj.v1i4.10063International Current Pharmaceutical Journal 2012, 1(4): 81-85

The current study was planned to evaluate comparative anti-inflammatory, analgesic and anti-pyretic activities of two newly synthesized organo-antimony (v) ferrocenyl benzoate derivatives with piroxicam. Anti-microbial activity of these compounds was also screened against two microorganisms. Analgesic effect of test compounds was evaluated by formalin-induced paw licking test in mice. The test compounds at 50 and 100 mg/kg b.w. doses exhibited significant (p<0.001) reduction of paw licking in treated mice comparable with standard drug piroxicam. Anti-inflammatory activity was assessed against carrageenan-induced paw oedema. The compound A produced anti-inflammatory effects comparable with standard piroxicam in dose dependent manner whereas compound B showed better effects than piroxicam at dose of 100 mg/kg body weight. To investigate anti-pyretic activity, fever was induced by administration of Brewer’s yeast in mice. Compound A showed highly significant inhibition of pyrexia (p<0.001) comparable to piroxicam after 3 hours while compound B (50 and 100 mg/kg) produced relatively lower anti-pyretic effect than standard drug. Antibacterial activity determined by disc diffusion method showed that compound B was relatively more effective than compound A against Staphylococcus aureus and Klebsiella pneumoniae. It is conceivable that both the tested compounds possessed anti-inflammatory, analgesic, anti-pyretic and anti-microbial effects even after the structural modification of parent compound.Bangladesh Pharmaceutical Journal 19(1): 15-24, 2016
