    Background: This survey was designed to assess and evaluate the prescription pattern of antibiotic drugs on patients suffering from ENT infection within Dhaka Metropolis, Bangladesh.Methods: A cross sectional, observational and prospective study was conducted from January to June 2015 in the out-patients (OPD) and in-patients (IPD) of ENT department at different general and specialized government and private hospitals (Dhaka Medical College and Hospital, Sir Solimullah Medical College Mitford Hospital, Holy Family Red Crescent Medical College and Hospital, Dhaka Community Medical College and Hospital) within Dhaka city.300 prescriptions were collected and randomly evaluated for this present study.Results: Out of 300 patients, 220 (73.33%) were male and 80 (26.67%) were female (including children and adults) where most of the patients were outpatients 262 (87.33%). In the patients information section it was observed that approximately 93.33%  prescription contained antibiotic drugs and almost all prescription (100%) contained antibiotic drugs along with other drugs such as 80.67% PPI (proton pump inhibitors), 76.67% analgesic and 51.33% vitamin/ iron supplements. From this analysis we found that 19.33% prescription contained single antibiotic drug, 80.67% contained two antibiotic drugs and no prescription contained more than two antibiotic drugs. Most of the prescribed drugs were administered orally (12% capsule, 80% tablet form). Out of 473 prescribed antibiotic drugs majority of them lie underβ-Lactam (54%) class followed by cephalosporin (46.33%) class in which maximum drugs (92%) were prescribed by their brand names.Conclusions: Prescribing more than one antibiotics was commonly encountered in this study indicating the occurrence of polypharmacy. Interventions to rectify over prescription of antibiotics, use of brand names, inadequate labelling of drugs is necessary to improve rational drug use. Standard treatment guidelines, hospital formulary, and educational intervention become essential to modify this behaviour to benefit the patient

    Background: This survey study was designed to analyze the current prescription pattern of anti-diabetic drugs that used in diabetic patients with cardiovascular complications within Dhaka metropolis.Methods: The present study has been conducted by out-patient department in a number of well-known general and specialized government and private hospitals in Dhaka, Bangladesh for 5 months. 1200 prescriptions and questionnaire were randomly evaluated for this present survey. A standard questionnaire was prepared, containing 17 different questions, to conduct the survey based on patient’s demographic data such as which type of diabetes they have contained, age, gender, education and their self-assessment of health, disease history and medication.Results: Among the patients involved in this study, there were 46% (550) male and 54% (650) female between the ages of 30 and 75 years. Between 46 and 70 years, 19% male and 31% female were found to be diabetic indicating that in this age group female are mostly affected by diabetes. About 2020 antidiabetic drugs were prescribed by the physicians in which 30.43% contained single, 54.16% contained two and 15% contained more than two anti-diabetic drugs. Amongst antidiabetic medications, metformin was the most commonly prescribed drug which was given in 30.69% patients followed by glimepride 10.9%, 5.45% had glipizide, 1% pioglitazone and other drugs. A total of 7.43% drug was prescribed by fixed dose combinations. Highest percentage of male diabetic patients with hypertension (86%), dyslipidemia (100%) and other complications (57%) was found at 75 years of age while no female patients were found under the same condition at the same age.Conclusions: The findings can serve as a guide to choose the formulation and combination of anti-diabetic drugs in this part of the world before developing & marketing any new drug. Therefore it is necessary to create better awareness among people, focus on rational use of anti-diabetic drugs and also motivate our physicians to prescribe the generic drugs

    Music is strongly linked to attention and giving attention can boost intelligence. The purpose of this study was to scrutinize the impact of soft, stimulating, and depressing songs on the attention of students. The study was performed on 280 undergraduate students. Students were divided into 4 groups (i.e., control, soft, stimulating, and depressing) and subjected to 3 songs, soft (That’s My Name), stimulating (Rain Over Me) and depressing (Broken Angel) songs. The Uddin’s Numeral Finding (NF) and Typo Revealing (TR) tests were used to analyze the attention of the students. In the NF, 75.54% attention was exerted by students subjected to stimulating song followed by soft song’s group (i.e., 74.32%) with respect to control group. Amid all groups, the lowest percentage, 70.77% of attention was reported for students subjected to the depressing song. For TR test, stimulating song’s group exerted highest, 45.97% attention, soft song’s group exerted 45.27%, control group exerted 42.70%, and lowest (i.e., 41.54%) attention was exerted by depressing song’s group. In NF test, concerning sex, amid male and female, male exerted higher (77.04%) attention than female but for TR test female exerted higher (i.e., 48.15%) attention for students subjected to stimulating song. Regarding the age of the study in case of NF test for stimulating song’s group, 18–20 years age students exerted highest, 82.07% attention but for TR test highest, 48.75% attention was reported for 23–25 years age students. For NF test, regarding the age of the study 1st-year student exerted highest, 92.44% attention but for TR test highest, 57.33% attention was reported for 3rd-year students for stimulating song’s group. Concerning residential status in both NF and TR tests, for students lived with family subjected to stimulating song exerted highest, 77.93% and 48.6% attention, respectively with respect to students lived without family and remaining groups. This study suggested that song influences the neuronal circuits linked to alert and cognitive functions and the stimulating song has the acme power of increasing attention while depressing song reduces the attention. Therefore, the exciting song can be an operative intervention for enhancing attention, cognitive functions, and treatment of associated neuropsychological disorders

    Model pharmacy has been adopted recently to upgrade the healthcare delivery system in Bangladesh. This study was aimed to analyze and compare the effectiveness of drug dispensing patterns, practices, and knowledge of both clients and dispensers of model pharmacies over traditional retail medicine shops. Two established methods, namely, client simulated method (CSM) and provider interview method (PIM), were employed to determine the practice differences in 90 retail medicine shops and 90 model pharmacies in and around Dhaka city. The results are represented primarily in comparison with corresponding percentages. The survey results did not fully support the findings obtained from the observations of the CSM as PIM contrasted these to some extent, and the differences are statistically significant (p<0.0001). According to CSM, the presence of A-grade pharmacists during working hours in retail medicine shops was 0%, and 63% in model pharmacies. As reported by PIM, in the retail medicine shops, 36% of clients were ignorant of visiting doctors before purchasing medicine. On the other hand, only 18% of clients could visit doctors. As per CSM, 40% of clients did not follow doctors' recommendations for completion of the full dose of antibiotics bought from retail medicine shops and 51% did not finish full antibiotic courses collected from model pharmacies. Additionally, CSM revealed that 28% of the clients administered leftover drugs following old and obsolete prescriptions of retail medicine shops and 21% of clients followed the same practices in terms of model pharmacies. The report of CSM revealed that 95% of dispensers of retail medicine shops sold medicine without prescription except over-the-counter (OTC), and in the model pharmacies, the percentage was 77%. The qualitative findings revealed substandard practices and dispensing pattern too. Model pharmacies were established to prevent aberrant medicine dispensing patterns and ensure proper medication dispensing practices and medicine intake. This research could not verify the situation that pharmacists or owners of model pharmacies were fully abiding by the guidelines set for them by the Directorate General of Drug Administration (DGDA)

    Neurochemistry refers to the chemical processes that occur in the brain and nervous system. This section of study determines how neurochemicals influence the network of neural operation. The brain transfers numerous chemical information via neurons to communicate. The main role of neurochemistry activities takes place in the brain, which allows it to perform numerous actions. Foundation of brain is a little bit different from man to man and several things can play a role in the levels of various neurotransmitters in the brain. It is supposed that differences in brain chemistry may accountable for a variety of behavioral disorders. A particular cell called neurons is the basis of brain. Neurotransmitters have the capability that it can trigger when ordered to do so, along with receptors for specific neurotransmitters. By sending messages with neurotransmitters to signal various cell activities, brain perform its functions. Neurotransmitter spreads chemical messages from neuron to neuron to broadcast certain work and thus it works. A neuron may accept many chemical messages, both positive and negative from the other neurons contiguous it. They are accountable to get the neuron to reply in different ways, or they may work combine to produce a certain effect. Since all of this occurs just within a split second, the neurotransmitter must be cleared away rapidly so that the same receptors can be activated again and again. Psychoactive drugs work by briefly influencing a man's neurochemistry, which thusly causes changes in a man's mind-set, cognition, perception and behavior. Neuropeptides are endogenous protein molecules that are utilized for neuronal signaling. These molecules exert more prolonged and diverse effects on behavior than neurotransmitters. Therefore the objective of this appraisal is to show study of the brain's chemical makeup especially neurotransmitters, psychopharmaceuticals, neuropeptides and their activities to nervous tissue

    The present study was undertaken to evaluate the analgesic and anti-inflammatory activities of ethanolic extract of Terminalia chebula (commonly known as Haritaki) fruits in experimental animal models. The study was carried out using Swiss Albino mice (20 - 25 g) and Long Evans rats (100 - 150 g) of either sex. The analgesic activity of Terminalia chebula was assessed by using hot plate method. For the determination of analgesic effect, doses of ethanolic extract of Terminalia chebula used in the present study were 250 mg/kg and 500 mg/kg body weight (BW). Anti-inflammatory effect was analyzed by carrageenan induced paw edema method with the administration dose of 300 mg/kg BW of animals. The analysis of experimental data was performed by statistical process of ANOVA to determine the variability of sample, while Dunnet’s test was performed for evaluation of comparative analgesic and anti-inflammatory activity of Terminalia chebula with control and standard. The animals were divided into four treatment groups of six animals each and the “Mean ± SEM” is the statistical identifiable value of the data and P values <0.05 was considered statistically significant. Hot plate test showed a significant increase in the mean reaction time to heat stimuli in hot plate method at both 250 mg/kg and 500 mg/kg BW doses throughout the observation period in 30 minutes and 60 minutes after treatment, which was comparable to the standard ketorolac and control group. In carrageenan induced paw edema method, considerable results were found after determining the percentage change in paw volume in extract. In both cases of analgesic and anti-inflammatory study, % inhibition of pain and inflammation were evaluated. Comparing with control, largest inhibition was found in inhibiting inflammation 5 hours after treatment, while the largest inhibition of pain was obtained in 30 minutes and 60 minutes after treatment of doses. The present study suggests that ethanolic extract of Terminalia chebula fruits has significant analgesic and anti-inflammatory activities.7 page(s

    Background:Oxidative stress is intensely linked with several pathological manifestations. Searching for medicinal plant with the superior safety profile for the treatment of oxidative stress related disorders are ongoing due to multiple unwanted effects associated with synthetic antioxidants. Therefore the purpose of this study was to examine the phytochemical content, in vitro antioxidant potentiality of crude methanol extract (CME), carbon tetrachloride fraction (CTF), petroleum ether fraction (PEF), chloroform fraction (CLF) and ethyl acetate fraction (EAF) of aerial parts of Gnaphalium luteoalbum (GL) L. Methods:The aerial parts of the GL were extracted with methanol followed by fractionation using carbon tetrachloride, petroleum ether, chloroform and ethyl acetate.The phytochemical screening of this plant was performed by using standard methods to evaluate the existence of alkaloids, carbohydrates, phenols, flavonoids, saponins, tannins, terpenoids and fixed oils.Antioxidant potentiality was estimated by, 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl (OH) and nitric oxide (NO) radical scavenging tests. Total antioxidant capacity (TAC), total phenolic content (TPC) and total flavonoid content (TFC) were also measured. Results: Phytochemical analysis of the aerial parts of GL confirmed the presence of carbohydrates, phenols, flavonoids and saponins in crude extract and its all fractions. The CME showed the highest scavenging activity (43.28%) with IC50 of 398.49 ÎĽg/mL in the DPPH radical scavenging test. The IC50 values of EAF, CME were statistically significant (P &lt; 0.05, P &lt; 0.01) with respect to ascorbic acid (ACA). For OH and NO radical scavenging tests maximum scavenging (48.39%, 69.64%) was also reported for CME compared to CTF, PEF, CLF and EAF. Compared to ACA, in case of OH and NO radical scavenging activities the IC50 values of CME were markedly significant (P &lt; 0.01, P &lt; 0.05). In the TAC test, CME showed the highest antioxidant activity (absorbance, 2.6 nm) related to other fractions. TPC was found to be the highest in the CME (115.96 mg of gallic acid equivalent/g of dried extract) rather than other fractions. The ranking order of CTF, PEF, CLF, EAF and CME for TFC was 48.67 &lt; 55.75 &lt; 65.29 &lt; 71.35 &lt; 82.29 mg quercetin equivalent/g of dried extract. Conclusion: The existing study suggested that CME of the aerial parts of GL can be used as a natural source of antioxidant which might be effective towards preventing or slowing oxidative stress related disorders

    Abstract Background Euphorbia hirta linn., is a species of Euphorbiaceae family. They are known as asthma plant, barokhervi. The plant E. hirta is famous for its medicinal importance among the tribal population. It is a common practice to use the whole to heal wounds. Several pharmacological properties including antiseptic, anti-inflammatory, antidibetic, antispasmodic, antibacterial, antiviral, antifungal, anticonvulsant, nootropic, antifertility and aphrodisiac properties have already been reported for this plant. The aim of present work was to evaluate the wound healing property in diabetic animals by oral and topical administration of ethanolic extract of E. hirta whole plant. Methods The ethanolic extract of E. hirta was subjected to determine the total phenolic content and total flavonoid content using galic acid and quercetin, respectively as standard. A single injection of alloxan monohydrate (120 mg/kg, i.p.) prepared in normal saline was administered to produce diabetes in rats, after overnight fasting. For analyzing the rate of contraction of wound, excision wounds sized 4.90cm2 and of 2 mm depth were used. Oral (100, 200 and 400 mg/kg/day; p.o.) and topical treatment with the extract (5% and 10% ointment 50 mg/kg/day) and standard (5% povidone iodine ointment 50 mg/kg/day) was started on the day of induction of wound and continued up to 16 days. The means of wound area measurement between groups at different time intervals were compared using ANOVA and Dunnet’s test. The diabetic wound healing mechanism was studied by measuring the plasma level of glucose, malondialdehyde (MDA) and nitric oxide (NO) in both control and treated groups. For the confirmation of activity, histopathology of the wounds tissues from excision wound model was performed. Results Phytochemical investigations showed the presence of various phytoconstituents (carbohydrates, saponins, alkaloids, glycosides, steroids, flavonoids, tannins). In the ethanolic extract of E. hirta the total phenol content was 285 ± 3.22 mg/g whereas the total flavonoid content was 118.46 ± 1.85 mg/g. In the present study, E. hirta caused significant wound closer both orally (35.92%, 44.69% and 61.42% at the doses of 100, 200 and 400, respectively) and topically (32.86% and 36.32% at the doses of 5% and 10%) treated groups as compared to diabetic control. However, the orally treated groups showed more significant effect than the topically treated groups. Moreover, oral administration of E. hirta ethanolic extract significantly reduced the blood glucose levels in diabetic wound rats (p  0.05). It also demonstrated a significant decrease in the plasma levels of lipid malondialdehyde and nitric oxide. The results of biochemical parameters were further supported by the histopathological changes of different organs (liver, pancrease, kidney, heart and skin from wound area) which were evidenced through a decrease in inflammatory cell infiltration. Conclusion The present study demonstrates that E. hirta whole plant extract promotes healing of wounds more significantly as compared to diabetic control rats, where healing is otherwise delayed

    Abstract Background The medicinal plants signify a massive basin of potential phytoconstituents that could be valuable as a substitute to allopathic drugs or considered as an analogue in drug development. Phyllanthus niruri L. (Euphorbiaceae) is generally used in traditional medicine to treat ulcer and inflammation. In this project we investigated the methanolic extract of leaves of Phyllanthus niruri for anti-inflammatory and anti-ulcer activity. Methods The anti-inflammatory activity of methanol extract of Phyllanthus niruri leaves was evaluated at the doses of 100, 200 and 400 mg/kg, p.o. while using ibuprofen (20 mg/kg, p.o) as the standard drug. The animals used were Swiss albino rats. Inflammation was induced by injecting 0.1 ml carrageenan (1% w/v) into the left hind paw. Paw tissues from the different groups were examined for inflammatory cell infiltration. On the other hand, antiulcer activity of methanolic extract of P. niruri leaves at the doses of 100, 200 and 400 mg/kg, p.o. were examined against ethanol-acid induced gastric mucosal injury in the Swiss albino rats - keeping omeprazole (20 mg/kg, p.o.) as reference. The rats were dissected and the stomachs were macroscopically examined to identify hemorrhagic lesions in the glandular mucosa. Results P. niruri significantly (p < 0.01) decreased carrageenan-induced paw edema; it exhibited a reduction of 46.80%, 55.32% and 69.14% at doses of 100, 200 and 400 mg/kg, respectively. These findings were further supported by the histological study. The methanolic extract also disclosed good protective effect against ethanol-acid induced gastric mucosal injury in the rats. Administration of the extract’s doses (100, 200 and 400 mg/kg) demonstrated a significant (p < 0.01) reduction in the ethanol- acid induced gastric erosion in all the experimental groups when compared to the control. The methanolic extract at the higher dose (400 mg/kg) resulted in better inhibition of ethanol-acid induced gastric ulcer as compare to omeprazole (20 mg/kg). Histological studies of the gastric wall revealed that toxic control rats revealed mucosal degeneration, ulceration and migration of numerous inflammatory cells throughout the section. On the other hand, MEPN treatment groups showed significant regeneration of mucosal layer and significantly prevented the formation of hemorrhage and edema. Conclusions The investigation suggests that methanolic extract of P. niruri leaf possess anti-inflammatory activity and promotes ulcer protection as ascertained by regeneration of mucosal layer and substantial prevention of the formation of hemorrhage and edema

    Background. Polyherbal formulations (PLFs) have been widely used for liver protection, treatment for hepatic dysfunction, and regeneration. They can also enhance appetite and protect the gastrointestinal tract from injury. In spite of the prevalent use, there is a need of scientific evidence on their effectiveness and safety. The objective of the present study was to assess the hepatoprotective effect of polyherbal formulations (commercially available in Bangladesh namely Heptaliv, Holyliv, Icturn, and J-deenar) in CCl4-induced hepatotoxicity in mice. Methods. In this study, Swiss albino mice were treated for 7 days with distilled water or PLFs (2.6 and 5.2 ml/kg body weight/day, per os.) followed by single subcutaneous injection of CCl4 (1 ml/kg body weight, diluted with olive oil in 1 : 1 ratio) on day 8. Twenty-four hours after CCl4 administration, the mice were monitored for the effects of PLFs on liver morphology, biochemical parameters including serum aspartate transaminase (AST), serum alanine transaminase (ALT), alkaline phosphatase (ALP), and total bilirubin. Phenobarbitone-induced sleeping time and histopathology changes in liver tissues were also monitored. Results. CCl4 administration caused significant hepatotoxicity as evidenced by marked elevation in AST, ALT, ALP, and total bilirubin. Phenobarbitone-induced sleeping time and infiltration of inflammatory cells and centrizonal necrosis on histological examination of liver demonstrated hepatic injury after CCl4 administration. However, the administration of Icturn and J-deenar polyherbal formulations at the higher dose significantly decreased the levels of AST, ALT, ALP, and total bilirubin. Moreover, pentobarbitone-induced sleeping time and histopathological analysis also revealed significant improvement as result of treatment with formulations Icturn and J-deenar. Conclusion. Our results confirmed that polyherbal formulations (Icturn and J-deenar) can significantly prevent CCl4-induced hepatotoxicity in mice, demonstrating their protective effect for liver
