ABSTRACT
An experiment was conducted at Tuber Crops Research Centre, BARI, Bogra during 2008-2009 to evaluate the organic amendment for controlling the stem canker and black scurf of potato. The different kinds of organic amendments were: T1 =Poultry refuse (PR) at 4 t ha-1, T2 =PR at 5 t ha-1, T3 =PR at 6 t ha-1, T4 =Mustard oil cake (MOC) at 300kg ha-1, T5 =MOC at 500kg ha-1, T6 =Neem oil cake (NOC) at 300kg ha-1, T7 =NOC at 500kg ha-1, T8 =Sawdust burning and T9 = Control. The experiment was laid out in a randomized complete block design (RCBD) with four replications. The organic amendment significantly influenced the disease incidence, yield attributes and yield of potato. The lowest disease incidence (17.5%) and per cent disease index (9.99) were found in T3 (poultry waste at 6 t ha-1). The minimum russet, deformed and Sclerotia infected tubers were also recorded in poultry waste at 6 t ha-1. The highest healthy tubers and tuber yield were found in the same treatment. Therefore, poultry manure 6 t ha-1 along with recommended dose of chemical fertilizer can be recommended to produce healthy tubers and maximum tuber yield of potato.
O experimento foi conduzido no (Centro de Pesquisa em Tubérculos ) Tuber Crops Research Centre, Bari, Bogra durante 2008-2009 para avaliar a alteração orgânica e controlar o cancro da haste e Black Scurf da batata. Os diferentes tipos de alterações orgânicas foram: T1 = Poultry recusar (PR) a 4 t ha-1, T2 = PR a 5 t ha-1, T3 = PR em 6 t ha-1, T4 = bolo de óleo de mostarda (MOC) em 300 kg ha-1, T5 = MOC em 500 kg ha-1, T6 = bolo de óleo de Neem (NOC) em 300 kg ha-1, T7 = NOC em 500 kg ha-1, T8 = queima de serragem e T9 = Controle. O delineamento experimental foi em blocos casualizados (RCBD) com quatro repetições. A alteração orgânica influenciou significativamente a incidência da doença, os atributos de rendimento e produtividade da batata. A menor incidência da doença (17,5%) por cento do índice de doença (9,99) foram encontrados em T3 (resíduos de aves a 6 t ha-1). O russet mínimo, deformado e Sclerotia tubérculos infectados também foram registrados em resíduos de aves a 6 t ha-1. O rendimento mais elevado tubérculos saudáveis e tubérculos foram encontrados no mesmo tratamento. Portanto, aviário 6 t ha-1, juntamente com a dose recomendada de fertilizante químico pode ser recomendado para a produção de tubérculos saudáveis e rendimento máximo dos tubérculos de batata.

Aims: The study was carried out to assess the analgesic, anti-inflammatory and CNS depressant activity of the methanolic extract of Abelmoschus esculentus Linn. Seeds. Study Design: The Present study was designed to observe pharmacological activities of the crude extract of the plant Abelmoschus esculentus seeds. The study consisted of hot extraction of the seeds of the A. esculantus with methanol. Afterwards, Methanolic crude extract was filtered and the filtrate was evaporated. Finally, screening of analgesic, antiinflammatory and CNS depressant activity of crude extracts of A. esculantus on Swiss Albino mice. Place and Duration of Study: Department of Pharmacy, Atish Dipankar University of Science and Technology, Dhaka, Bangladesh. January, 2013- July 2013. Methodology: The animals are divided into Four groups and each group consists of five mice. Analgesic activity was performed by acetic acid-induced writhing model and formalin induced licking and biting in mice. Anti-inflammatory effects of Abelmoschus esculentus seed extract were done by carrageenan induced anti-inflammatory method at the dose of 100 and 200 mg/kg b.wt., (p.o). The CNS depressant activity was evaluated by observing the reduction of locomotor and exploratory activities in the hole cross and opens field tests at the dose of 100 and 200 mg/kg body weight. Results: In statistical analysis, the dose (200 mg/kg) was found to exhibit (significant p=0.05) better analgesic activity (65.16% and 54.38%) against both acetic acid and formalin induced pain in mice which is about similar to standard drug Indomethacin. The extract of A. esculentus (100 and 200mg/kg) also showed sustained inhibition (54.97% and 65.56%) of paw edema at the 4th hour compared to Indomethacin (74.17%). Besides this A. esculentus (significant p=0.05) seed extract (100 and 200mg/kg p.o.) also possesses depressant activity at 90min in both methods. Conclusion: this study recommends that the methanolic extract of the Abelmoschus esculentus seeds has significant CNS depressant, analgesic and anti-inflammatory properties.
ABSTRACT
Aims: This research investigated the thrombolytic, cytotoxic and antidiabetic effects of Paederia foetida leaf methanol extract. Place and Duration of Study: Department of Genetic Engineering and Biotechnology and Department of Biochemistry and Molecular Biology, University of Chittagong, Bangladesh, between April to December, 2012. Methodology: An in-vitro thrombolytic model was used to check the thrombolytic effect of Paederia foetida extract using streptokinase as a positive control. Cytotoxic effect was measured by Brine shrimp lethality bioassay. Antidiabetic effect of the extract was conducted in alloxan induced diabetic model of Swiss albino mice. Data were analyzed by one way ANOVA using statistical package for social science (SPSS) software. Results: In in-vitro thrombolysis, Paederia foetida extract (100μl) lysed 21.40 ± 1.39 %, Streptokinase (positive control) 81.42 ± 0.88 % and water (negative control) 4.63 ± 0.31% of the blood clots. These clot lysis values were statistically different (p<0.05) from each other. In Brine shrimp bioassay, lethal concentration (LC50) of Paederia foetida extract was found 65.31 μg/mL which was statistically significant compared to Vincristine sulfate (positive control, LC50=0.76 μg/mL). The extract showed a significant and dosedependent decrease in blood glucose level in alloxan induced diabetic mice. The effect of the extract was comparable to the reference antidiabetic drug metformin (150 mg/kg BW). Conclusion: The results demonstrated a moderate thrombolytic, cytotoxic and antidiabetic effect of Paederia foetida leaf extract to be analyzed further for prospective pharmaceutical preparation.
ABSTRACT
Background: Diclofenac sodium is a non-steroidal anti-inflammatory drug with reportedly undesirable harmful side effects including blood disorders, abdominal pain, ulceration and bleeding of the stomach or intestine. Objective:The present study was conducted to investigate the effect of diclofenac sodium on erythropoiesis, on stomach and liver under different conditions. Method: This experimental study on animal model was conducted in the Department of Physiology, Bangladesh Agricultural University, Mymensingh, between July and August 2007. A total of 45 Swiss Albino mice were randomly assigned into five equal groups (n=9) and they all were fed with standard broiler pellet (25 gm/mice/day) throughout the experimental period of 40 days. Keeping 1 group as control(groupA), 4 groups were treated with diclofenac sodium @ 3 mg/kg body weight (bwt) orally in empty (group B)or full stomach with (group c) or without vitamin B12(group D) @ 10 μg/Kg body weight through intramuscular route. Total erythrocyte count (TEC) and Hb% was determined to assess erythropoiesis. Macroscopic and microscopic changes of liver and stomach were studied by standard laboratory method. Data were analyzed statistically by ANOVA and un paired t test. Result: Oral administration of this drug significantly (p<0.01) decreased Total Erythrocyte Count(TEC) and Hb in the animals treated with diclofenac sodium in empty stomach and in the animals treated with diclofenac sodium plus vitamin B12 in empty stomach. All the treated mice showed slight to moderate congestion of the gastric mucosa and liver. Conclusion: Intake of diclofenac sodium in empty stomach may produce harmful side effect on stomach and liver.
