Curry (Muraya koenigii) leaf is an essential leafy spice used widely in cuisine for its distinct flavor and for other medicinal purposes: Analgesic, antidysenteric, antioxidant and in regulating fertility. The Morris water maze was used to study the effects of aqueous extracts of M. koenigii (curry) leaf on learning and memory. Aqueous leaf extracts of M. koenigii (80mg/kg, p.o.) was administered to 7 CD1 strain of mice (18-28 g body weight) while the control group received 0.1 ml/10 kg body weight of distilled water (orally) for 10 days before behavior was assessed. All mice were tested in the Morris water maze for 8 days: At 4 trials per day and 60 seconds per trial. Day 1-3 were for acquisition training, day 4-6 reversal training, day 7, the probe trail and day 8 visible platform task. Results indicate that swim latency were not significantly different between the groups during acquisition and reversal training. The retention quadrant duration was significantly higher for the M. koenigi-treated mice compare to the control (P<0.05). The mice treated with M. koenigi showed a negative weight gain, indicating weight loss (p< 0.05). Therefore the aqueous extracts of M. koenigi improved visuospatial memory in the mice and decreased body weight.

Aim: The phytochemical screening, antibacterial activities and in vivo toxicity of extracts of the leaves of scent leaf (Ocimum gratissimum L.) were investigated. Methods: All the analyses were carried out using standard scientific procedures using Soxhlet extraction, well-diffusion agar antimicrobial testing and in vivo acute toxicity testing. Results: The phytochemical analysis according to standard screening tests using conventional protocols revealed the presence of anthraquinone, saponins, tannins, terpenoids and alkaloids, which were detected in methanol extract analyzed. But, flavonoids, glycosides, phlobatannins and steroids were not detected in the methanol extracts analyzed. While only flavonoids were detected in chloroform extract. All other phytochemicals were absent. The extract fractions generally exhibited slight antibacterial activities on Staphylococcus aureus, Bacillus subtilis, Salmonella Typhi and Escherichia coli. But, the extracts showed no effect against Candida albicans. The minimum inhibitory concentration of O. gratissimum was determined with S. aureus and B. cereus recording MICs at the lowest concentration (12.5 mg/mL) of the methanol and chloroform extracts used. While methanol and chloroform extracts were found to have recorded moderate activity S. Typhi and E. coli at the MIC of 50mg/mL. The methanol and chloroform extract recorded MBC of 50 mg/mL on B. subtilis and S. Typhi. However, Salmonella Typhi was inhibited at the concentration of 100 mg/mL of chloroform scent leaf extract. The MICs of C. albicans were not determined in the methanol and chloroform scent leaf extracts analyzed. The in vivo toxicity of O. gratissimum extracts against albino rats revealed that the plant extracts were found to exhibit mild toxicity at higher doses, but the overall remark showed that the plant extract was safe at various concentrations. Conclusions: The plant can be used in the treatment of various diseases caused by the test microbes, and the plant has less toxicity when administered orally.

Aim: This study sought to investigate the effect of methanolic extract of Vernonia amygdalina leaves on glycemic and lipidaemic indexes of Wistar rats. Methods: Fresh plants of V. amygdalina were harvested from the Institute of Agricultural Research and Training, Ibadan. The leaves were dried and extracted using soxhlet apparatus and methanol was used as the solvent. The solvent was recovered in a rotary evaporator at 35°C with a yield of 2.24 g which represents a percentage yield of 8.96%. Ten adult male Wistar rats with body weight between 100 and 120 g were used for this study. They were randomly divided into two groups of five rats each. Animals in group 1 were administered normal saline while those in group 2 were administered V. amygdalina extract. The animals were exposed to the extract and saline solution at a dose of 3 mL per 100 g body weight 12 hourly via oral route of administration. After fourteen days of administration, the animals were fasted overnight and anaesthetized using diethyl ether. Blood samples were collected by cardiac puncture. Fasting blood sugar and lipid profile were determined using standard methods. Results: V. amygdalina leaves was observed to significantly lower fasting blood sugar, total cholesterol, triglyceride and VLDL-cholesterol but had no significant effect on the concentrations of HDL-cholesterol, LDL-cholesterol and HDL/LDL-cholesterol ratio when compared to those of the control group at p<0.05. Conclusion: The lowering effect of V. amygdalina leaves on fasting blood sugar indicated that it has the propensity to be antidiabetic. Its effect on total cholesterol and triglyceride showed that V. amygdalina leaves could be useful in the control of obesity and hypertension.

This study investigated some effects of aluminium chloride on the cerebral cortex of adult Wistar rats. Aluminium chloride as one of the toxic metals has been known to be one of the major environmental pollutants across the world which has been reported in relation to Neurodegenerative diseases (ND) associated with metallic intoxication. It is present in many pharmaceutical drugs, food products and also used in the treatment of domestic water being involved in skeletal, haematological and neurological diseases. Thirty-two adult Wistar of both sexes weighing between 143 g-189 g were randomly grouped into four groups, group A, B, C and D each group containing 8 rats. Group A rats which were the controls, were maintained on standard feed (grower mash) and water for 21 days. Rats in group B, C and D were treated with 0.2 g/kg, 0.4 g/kg and 0.6 g/kg of aluminium chloride respectively for 21days. The aluminium chloride solution was administered orally on a daily basis for that period. The weight of the Wistar rats was recorded on a weekly basis (before and at the end of each week of administration). On the 22nd day the Wistar rats in group A, B, C and D were sacrificed by cervical dislocation, blood was collected through cardiac puncture, the brain was removed and weighed immediately using sensitive balance, part of the brain of all Wistar rats in each group was collected and homogenized for biochemical analysis, the remaining part was then fixed in 10% formol saline, the tissue was processed and sectioned at 5µm and stained with hematoxylin and eosin for histological study. Results showed that the mean body weights of the Wistar rats significantly increased in the treated groups when compared with the control group. The mean brain weights of the aluminium- treated groups showed insignificant decreased (P>0.05) when compared to the control group. In the biochemical analysis, there was a statistically significant increase (P<0.05) in the level of Malondialdehyde (MDA) in the aluminium-treated groups, and a significant decrease (P<0.05) in the level of Superoxide dismutase (SOD), and Succinate Dehydrogenase (SDH) in the aluminium treated group. Histological study of the brain (cerebral cortex) revealed that the cerebral cortical layers of the aluminium treated groups appeared distorted and degenerated, in a dose-dependent manner. The study concluded that aluminium chloride has a neurotoxic effect on the cerebral cortex of adult Wistar rats which invariably may alter some cerebral functions.
本研究探讨了氯化铝对成年Wistar大鼠大脑皮层的影响。氯化铝作为一种有毒金属，是世界范围内主要的环境污染物之一，已被报道与金属中毒相关的神经退行性疾病(ND)有关。它存在于许多药品、食品中，也用于处理与骨骼、血液病和神经疾病有关的生活用水。选取体重143 g ~ 189 g的雄性成年Wistar大鼠32只，随机分为A、B、C、D组，每组8只。A组大鼠为对照组，饲喂标准饲料(种植者醪)和水21 d。B、C、D组大鼠分别给予0.2 g/kg、0.4 g/kg、0.6 g/kg氯化铝处理21 D。在此期间，每天口服氯化铝溶液。每周(给药前和给药周结束时)记录Wistar大鼠体重。第22天，A、B、C、D组Wistar大鼠颈椎脱臼处死，经心脏穿刺采血，立即取脑组织，用灵敏平衡法称重，每组Wistar大鼠取部分脑组织，均质化进行生化分析，剩余部分固定于10%福尔mol生理盐水中，在5µm处处理切片，苏木精和伊红染色进行组织学研究。结果显示，与对照组相比，各给药组Wistar大鼠的平均体重明显增加。与对照组相比，铝处理组的平均脑质量下降不显著(P>0.05)。生化分析中，铝处理组丙二醛(MDA)水平显著升高(P<0.05)，超氧化物歧化酶(SOD)、琥珀酸脱氢酶(SDH)水平显著降低(P<0.05)。脑(大脑皮层)的组织学研究显示，铝处理组的大脑皮层出现扭曲和退化，并呈剂量依赖性。该研究得出结论，氯化铝对成年Wistar大鼠的大脑皮层有神经毒性作用，这必然会改变一些大脑功能。

Aim: This study aimed to evaluate the mechanical and in vitro release properties of diazepam from tablets containing fluid bed dried and lyophilized microcrystalline cellulose (MCC) obtained from the matured fruit husks of Cocos nucifera (CN). Study Design: Method of experiment. Place and Duration of Study: Department of Pharmaceutical Technology and Industrial Pharmacy, University of Nigeria, Nsukka from March 2015 to September, 2016 Methods: Dried CN fruit husks were digested in sodium hydroxide to obtain alpha (α) cellulose which on hydrolysis with mineral acid (Hydrochloric acid) solution gave CN-MCC. The dry MCC obtained by either fluid bed or lyophilized drying of the wet CN-MCC were coded MCCF-Cocos and MCCL-Cocos respectively. Both MCCs were used in the formulation of diazepam tablets at 20, 30 and 40% w/w. Avicel PH 102 (AVC-102), was used as comparing standard. The tablets were evaluated for physical and dissolution properties using standard methods. Results: Results show the tablets passed the British Pharmacopoeia specifications for weight uniformity, crushing strength, disintegration time, friability and dissolution. Diazepam tablets containing MCCL-Cocos (coded DCL) were mechanically stronger than those containing MCCF-Cocos (coded DCF). Disintegration time was in the order of DCF > DCL tablets while friability was in the order of DCL < DCF tablets. Diazepam tablets containing AVC-102 (coded DAV) were mechanically stronger than DCL and DCF tablets. The dilution potential was in the order DAV > DCL > DCF. More than 80% of the diazepam content was released from DAV, DCL and DCF tablets. Conclusion: Generally, DAV, DCL and DCF tablets met the British Pharmacopoeia limits for mechanical properties and in vitro drug release with DCL tablets showing significantly (P = .05) superior mechanical properties while DCF showed faster drug release.

Moringa oleifera, popularly known as “miracle tree” belongs to the family, Moringaceae. It is a medicinal plant in which the leaves are the most nutritious part, being a significant source of vitamins and protein among others. This study was conceived and designed based on the gaps in the research that has been performed and what is known about the plant. In this study, the effect of Moringa oleifera leaves extract on alloxan induced diabetes in Wistar albino rats was investigated. A total of forty five (45) rats were acclimatized for a period of two weeks, then randomly divided into five (5) groups (1, 2, 3, 4, and 5) of nine (9) rats each and fed with standard feed and water. Group 1 which is the control was fed with just water and standard feed while Hyperglycemia was induced in groups 2, 3, 4, & 5 intra-peritoneally after an over-night fasting using alloxan at a concentration of 130 mg/kg b.w. and allowed for 48hours which resulted in a high blood glucose level between 300 mg/dl and 600 mg/dl. Group 2 was not given any treatment while Groups 3, 4, & 5 were treated with doses 100 mg/kg b.w., 200 mg/kg bw, and 400 mg/kgbw of Moringa oleifera leaf extract respectively for a period of four weeks. A glucometer was used to check the blood glucose level of the animals before and after treatment. The results of Groups 3, 4, & 5 (172.0±4.75 mg/dl, 142.9±47.25 mg/dl, 70.6±24.46 mg/dl respectively) showed a significant decrease (p< 0.05) in blood glucose level of the induced rats when compared with Group 2 (316±47.17 mg/dl) which was induced only alloxan. It can therefore be concluded that this study has shown that the extract of Moringa oleifera leaves offers an anti-diabetic effect in Wistar albino rats.

Aims: To investigate the mechanical and in vitro release properties of chlorpheniramine maleate (CM) tablets formulated with fluid bed dried and lyophilized microcrystalline cellulose (MCC) derived from the fruit husk of Cocos nucifera (CN). Study Design: Experimental design. Place and Duration of Study: Department of Pharmaceutical Technology and Industrial Pharmacy, University of Nigeria, Nsukka from January, 2015 to December, 2016. Methods: Chips of matured (CN) fruit husk were de-lignified by soda treatment methods to obtain alpha cellulose which was hydrolyzed with mineral acid (Hydrochloric acid) to obtain CN-MCC. A portion of the damp CN-MCC was fluid bed dried at 60°C for 2 h (coded MCCF-Cocos) and the remaining CN-MCC was lyophilized at -45°C for 3 h (coded MCCL-Cocos). The MCC powders were blended with 20, 30 and 40% w/w CM and directly compressed at 9.81 mega Pascal (mPa). The CM tablets containing MCCF-Cocos (coded CM-CF) and MCCL-Cocos (coded CM-CL) were evaluated using standard methods. Results: Both batches had tablets with minimal weight variation; CM-CL tablets were mechanically stronger (P = .037) and less friable than CM-CF tablets. CM-CL tablets took a longer time to disintegrate than CM-CF tablets. Comparatively, CM tablets containing AVC-102 (coded CM-AV) were mechanically stronger, less friable and had a longer disintegration time than CM-CL and CM-CF tablets. The dilution potential of CM-AV was greater than CM-CL and CM-CF tablets. CM release was faster in CM-CF. There was more than 80 % release of CM from CM-CF, CM-CL and CM-AV tablets within 30 min. Although CM-CL tablets were mechanically stronger than CM-CF, the data for all batches of the tablets obtained fell within the British Pharmacopoeia set limits for uncoated tablets. Conclusion: Chlorpheniramine maleate tablets containing fluid bed dried and lyophilized microcrystalline cellulose obtained from C. nucifera had good mechanical and in vitro release properties.

Background: The choice of choosing right anti-microbial therapy in hospitals depends on the knowledge of local anti-microbial susceptibility profile. This retrospective study was conducted to assess the in vitro susceptibility pattern of different pathogen isolates to various antibiotics including Cefepime-Amikacin-Antibiotic resistant breakers (ARBs)* in various hospitals across the Jaipur City. Methods: To characterize the antimicrobial susceptibility pattern of different isolates from various hospitals across the Jaipur City, a retrospective, observational analysis was done for antibiogram data. A total of 1201 Gram negative isolates collected during the period from January 2017 to December 2017 were included in the study. Antibiotic sensitivity testing was done in accordance with the recommendations of Clinical Laboratory Standard Institute (CLSI) guidelines. Results: Of the total 1201 Gram negative isolates included in this study, 51.6% were from wounds and pus specimens, 40.1% were from respiratory and 8.2% from blood. P. aeruginosa (49.7%) was the most frequently isolated pathogen distantly followed by A. baumannii (21.6%), K. pneumoniae (16.6%) and E. coli (12.1%). The highest susceptibility was reported to polymyxins (100%) including Colistin and Polymyxin B, among all the tested bacteria’s and system wise. Among all the antibiotic tested, (Cefepime-Amikacin-ARBs*) sensitivity ranged for 87.9% to 52% on pathogens (E. coli, K. pneumonia, P. aeruginosa) tested from samples of skin and soft tissue, respiratory tract, blood stream, followed by Meropenem ranged for 78.4% to 55% on pathogens (E. coli, K. pneumonia, P. aeruginosa), followed by ceftazidime-tazobactam ranged for 82.7% to 58% on pathogens (E. coli, K. pneumonia, P. aeruginosa) and 22.7% sensitive for A. baumannii to Cefoperazone sulbactam. Based on pathogen type, E. coli exhibited highest overall susceptibility and the lowest was reported by A. baumannii. The susceptibility of A. baumannii ranged from 1-26% to all the tested antibiotics except polymyxins with 100% susceptibility. Conclusions: This in vitro susceptibility data suggests that Cefepime-Amikacin-ARBs* can serve as important therapeutic option for the treatment of various resistant Gram-negative bacterial infections to relieve the excess pressure on last resort antibiotics, carbapenems and other drugs including Colistin and polymyxin B. Cefepime-Amikacin-ARBs*on the basis of antimicrobial susceptibility data can be considered as an effective therapeutic option for carbapenems in treating gram negative bacterial infections, and could be considered as a broad spectrum antibiotic sparer’s like carbapenem, colistin and Polymyxin B.

Cystic Fibrosis (CF) is a progressive clinical condition associated with decreased functionality of glands that produce mucus, sweat, and intestinal secretions. CF is one of the most common recessive genetic diseases that affect all ethnic groups without any known identified cure, having variations in the severity of symptoms. In the treatment and management of CF, The choice and routes of administration of antibiotics taken is important in assessing effectiveness at different populations. In the light of this, current study was undertaken to determine the efficacy of Nebulised Tobramycin (NT) in the treatment of mild to moderate CF within 8years study period. Study was achieved by searching known repositories and electronic databases of various sources. Randomized Clinical Trials (RCTs) that compares patients treated on NT and placebo were selected, including six (6) RCTs comprising 609 participants to the review. Study noticed significant clinical and methodological heterogeneity among trials with NT, varying over a total of 8years study period. Also, there were recorded evidences of improvement in pulmonary function in most of the patients, following completion of the study. This review revealed inconclusive evidence in the efficacy of NT in the treatment of mild to moderate CF. It is thus clear, that long term use of NT in mild to moderate CF can provide sustained improvements in pulmonary functions.

Aim: This study is aimed at investigating the prophylactic efficacy of combined extract of Curcuma longa and Moringa oleifera leaf against indomethacin–induced ulcer in albino rats. Place and Duration of Study: This research was carried out in Ibadan Nigeria between November 2017 and January, 2018. Methods: Fifty (50) healthy male albino rats with body weights between 150 and 200 g were used for this study. They were randomly divided into ten groups of five rats each. Group I was administered omeprazole for seven days, group II was administered Moringa oleifera leaf solution for seven days, group III was administered Curcuma longa solution for seven days, group IV was administered Curcuma longa + Moringa oleifera leaf solution for seven days and group V was administered distilled water for seven days. This group served as the control group. Groups VI, VII, VIII, IX and X were treated similarly as groups I, II, III, IV and V respectively but were treated for fourteen days. At the end of the administration, the animals were fasted for 18 hours and 50 mg/kg of indomethacin was administered orally (p.o) to the rats. After 8 hours of indomethacin administration, the animals were anesthetized by chloroform anesthesia and sacrificed and the stomach removed and opened along the greater curvature, rinsed with copious volume of normal saline and pinned on a board to expose the stomach clearly. Results: Animals treated with combined extracts of Curcuma longa + Moringa oleifera leaf showed significantly increased ulcer inhibition (71.64%, 75.57%) when compared with those of Curcuma longa (44.10%, 46.53%) and Moringa oleifera leaf (53.43%, 57.58) respectively but showed no significant difference when compared with that of omeprazole (72.60%, 74.29%), the reference drug after 7 and 14 days pre-treatment respectively. Conclusion: The combined extract has a greater prophylactic efficacy against indomethacin-induced ulcer than individual extracts and gave similar result as omeprazole. The combined extract of Curcuma longa + Moringa oleifera leaf could be used as a prophylaxis against peptic ulcer disease.
