The role of systemic antibiotics in root canal treatment (RCT) always remained controversial. To exactly identify the state of affairs, regarding whether or not the usage of systemic antibiotics in RCT, the current meta analysis was carried out. To identify the frequency of discouraging or preferring the use of systemic antibiotics in RCT. Secondly to identify the efficacy of various antibiotics in post RCT infections. Department of Operative Dentistry, Rawal Dental College Islamabad and Pathology Department of Al Nafees Medical College & Hospital, Isra University Islamabad Campus, Pakistan. Total 41 published studies in 03 and a half decades were included in the study i.e 1981 – 2017. Various authentic electronic sources were used to gather adequate and authentic data by simple random sampling technique. 66.6%(n=08) studies from 1987 till 2011, were not in favour of using systemic antibiotics as a part of RCT. While 33.3% (n=04) preferred using systemic antibiotics for RCT. Regarding the local antibiotic preference, 33.3% (n=04) studies were in favour of using a combination of triple antibiotic paste comprising of metronidazole, minocycline and ciprofloxacin. There is no role of systemic/local antibiotics in endodontic management. However, the use of antibiotics is only recommended if deemed necessary by viewing the premorbid of patient.

Evidence exists in literature to support involvement of community pharmacists in a broad range of preventive health activities especially in developed countries. There is a need to explore extent of pharmacists’ involvement in resource limited countries. The objectives of this study were to describe community pharmacists’ involvement in disease prevention strategies and explore facilitators and barriers to involvement. A forty item pretested self- completion questionnaire with 0.944 reliability was administered to a convenient sample of 500 community pharmacists in 3 major cities in Nigeria. Self- reported involvement  in preventive health strategies was evaluated on a 5 point response scale ranging from 1 (Not involved at all ) to 5 (very much involved). Response rate was 90.6% (453/500). Mean scores on face to face delivery of preventive health service was consistently higher than leaflet or text message. Pharmacists were mostly involved in preventive health services in the area of hypertension mean (4.38±0.91) followed by Diabetes (4.35±0.86)  ST1 (4.27±0.84) and weight reduction (3.39±1.37). Areas of least involvement include osteoporosis (2.2±1.25), hyperlipidemia (2.9±1.43), travel health (2.33±1.33) and cancer risk assessment (1.67±0.96). Lack of adequate training was the most frequent reason for low level of involvement. Community pharmacists in Nigeria are involved to varying extent in a wide range of preventive health activities. Areas of low involvement in this study indicate a need for capacity building in order to increase level of community pharmacist involvement in preventive health activities.

In an attempt to competitively inhibit other organisms within the same environment, microbial cells produce a wide range of bioactive bacteriocins and bacteriocin-like extracellular metabolites (BLEM). Bacterial species (Bacillus and Pseudomonas) were isolated from soil samples, screened for BLEM production and the crude activity of cell free metabolites determined by agar diffusion assay. Partial purification of metabolites was achieved by protein precipitation with ammonium sulfate and BLEM sensitivities to temperature, pH, surfactant and ultraviolet radiation along with the mode of action of partially purified BLEM on indicator strains and other pathogens were characterized.Bacillus subtilis SF8 and Pseudomonas aeruginosa SF4 produced BLEM inhibitory to closely related strains with partially purified activity units of 768 and 2048AU/mL respectively. BLEMs retained large percentages of their inhibitory activities over a wide range of temperature and pH, 71%, 92% and 80% activity was retained by BLEM from B. subtilis SF8 while 91%, 81% and 89% activity was retained by BLEM from P. aeruginosa SF4after 60 minutes of BLEM pre-incubation at 900C, pH 4 and 10, respectively. Ultraviolet radiation enhanced BLEM production in P. aeruginosa SF4 but not in B. subtilis SF8. Fourier Transformed Infrared (FTIR) spectroscopy revealed that BLEMs from both B. subtilis SF8 and P. aeruginosa SF4 interfered with cell membrane components of B. macerans SF2 and P. fluorescence BS2 respectively. The BLEM also had a broad inhibitory range on test bacterial and fungal pathogens.

The prolonged usage of antiepileptic drugs has necessitated the need to study their toxicological profiles using in experimental animals. The toxicological effects of carbamazepine (CBZ) and levetiracetam (LEV) on some biochemical and haematological parameters were evaluated in rats. Haematological parameters evaluated include packed cell volume (PCV), Haemoglobin (Hb) and white blood cell (WBC), while some biochemical parameters studied were liver enzyme tests such as alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lipid profiles tests such as total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). In addition, the body weight and morphological assessment of the vital body organs were determined. Results showed that CBZ and LEV did not significantly affect the haematological parameters. Animals treated with CBZ showed a significant increase in TC and HDL levels at 400 and 1000 mg/kg doses. There was no significant increase in the TC, HDL, LDL and TG in rats treated with LEV. CBZ and LEV treated animals at the doses of 400 and 1000 mg/kg showed a significant increase in body weights from the 6th day after commencement of treatment. There was also a significant increase in the weights of the liver, kidney and heart of the animals treated with CBZ and LEV. The colour and texture of the organs did not change. However, no appreciable weight increase was observed with the lung.

Cola parchycarpa is one of the under-utilized monkey kola plants that yield edible tasty fruits. The amino acids, vitamins, mineral elements, proximate and anti-nutrients composition of the white aril, seed and fruit epicarp were evaluated using standard procedures. The total essential amino acids ranged from 31.84-55.70 g/100 g, predominated in lysine, leucine and cysteine. The fruit pulp and epicarp contained substantial amount of ascorbic acid (6.310 and 6.646 mg/100 g) and tocopherols (7.328 and 5.314 mg/100 g), respectively including vitamin B1, B2, B3, B5, B6, B9 and K1. Potassium, zinc and manganese were relatively high in the seed while calcium, magnesium and iron dominated in the fruit epicarp. The proximate analysis data of the fruit pulp and epicarp were similar except in protein and lipid content. Anti-nutritional factors (phytate, oxalates, cyanide and tannins) were below permissible limits.  This is the first report on amino acids and detailed vitamins composition of C. parchycarpa. These findings indicate the rich nutritional potential of this tasty fruit and further processing into other value added products would encourage conservation and subversion of its impending extinction.

Infection with H. pylori is an up growing  public health problem that affects approximately 50% of people in industrialized nations, and up to 80% in developing countries. Helicobacter pylori (H. pylori) infection had been identified as the main causes of peptic ulcer disease (PUD). Blood group A phenotype was associated with gastric ulcer (GU) and gastric carcinoma, while blood group O phenotype found to be associated with duodenal ulcer DU predominantly; however, no explanation for this association was received. This study was conducted to, first, determine the relationship between ABO blood groups and H. pylori infection in peptic ulcer patients, and second, to study the response to the two weeks H. pylori eradication triple therapy in peptic ulcer patients carrying different blood groups. A total of  84 patients who presented  with symptoms of PUD and showed positive endoscopic examination of PUD and evidence of H. pylori infectionby histology and stool antigen test, were divided into four groups according to ABO blood group phenotype. All H. pylori infected patients received standard H. pylori eradication triple therapy for 14 days duration. Patients were followed up by re- endoscopic examination after 2 months of treatment course. The percentage of H. pylori infection in patients with peptic ulcer disease carrying blood group O was higher than other blood group phenotype. In H. pylori-infected peptic ulcer patients, higher incidence of gastric ulcer (GU) was noticed among blood group A carriers, while higher incidence of duodenal ulcer (DU) was found among blood group O carriers when compare with other blood group phenotypes.  Fourteen days triple therapy showed lower eradication rate in H. pylori infected blood group O peptic ulcer patients, while a higher response to the standard H. pylori eradication triple therapy was found among patients with blood group B phenotype.

The aim of the study was to investigate adaptogenic and anxiolytic activities of methanol extract of Piper longum fruits at different dose levels (100, 250 and 500 mg/kg) using different experimental animal models. In the present research work antistress activity was assessed by swimming endurance and immobilization stress models, and anxiolytic activity were assessed by elevated plus maze behavior of mice, light dark exploration test in mice and open field apparatus test in rats. In swimming endurance test, the mean time of swimming performance and swimming stress induced biochemical parameters such as serum cortisol, the weights of adrenal glands, ascorbic acid and cortisol levels were recorded in the adrenal gland. There was dose dependent significant increase in swimming performance time observed in mice pretreated with graded doses of the test extracts.  Animals pretreated with test extracts at different dose levels showed significant and dose dependent fall in all the biochemical parameters, as compared to the stress control animals. Treatment with standard and test extracts significantly reversed the stress induced altered hematological parameters, biochemical parameters, organs weight, GSH and LPO levels and neurotransmitters such as dopamine, nor adrenaline and serotonin levels in rat brain In immobilization stress. The test extracts demonstrated the significant increase in time spent and number of entries into open arm in elevated plus maze apparatus test and also increase in time spent and number of entries into lit box was observed in light box exploration test and reduction in time spent and number crossing into the dark compartment observed in animals pretreated with test extract. Pretreatment with test extracts demonstrated dose dependent significant increase in ambulation, rearing and self-grooming and significant decrease in fecal dropping in case of open field test.
