Anti-hyperglycemic and anti-hyperlipidemic effects of a methanolic extract of Debregeasia salicifolia in Alloxan-induced diabetic albino mice

Abstract Diabetes mellitus (DM), an endocrine syndrome characterized by high blood glucose levels due to abrogated insulin activity. The existing treatments for DM have side effects and varying degrees of efficacy. Therefore, it is paramount that novel approaches be developed to enhance the management of DM. Therapeutic plants have been accredited as having comparatively high efficacy with fewer adverse effects. The current study aims to elucidate the phytochemical profile, anti-hyperlipidemic, and anti-diabetic effects of methanolic extract D. salicifolia (leaves) in Alloxan-induced diabetic mice. Alloxan was injected intraperitoneally (150 mg kg-1, b.w), to induced diabetes in mice. The mice were divided into three groups (n=10). Group 1 (normal control) received normal food and purified water, Group II (diabetic control) received regular feed and clean water and group III (diabetic treated) received a methanolic extract of the plant (300 mg kg-1) for 28 days with a typical diet and clean water throughout the experiment. Blood samples were collected to checked serum glucose and concentration of LDL, TC, TG. The extract demonstrated significant antihyperglycemic activity (P 0.05), whereas improvements in mice's body weight and lipid profiles were observed after treatment with the extract. This study establishes that the extract has high efficacy with comparatively less toxicity that can be used for DM management.

Resumo Diabetes mellitus (DM) é uma síndrome endócrina caracterizada por níveis elevados de glicose no sangue devido à atividade anulada da insulina. Os tratamentos existentes para o DM têm efeitos colaterais e vários graus de eficácia. Portanto, é fundamental que novas abordagens sejam desenvolvidas para aprimorar o manejo do DM. As plantas terapêuticas foram acreditadas como tendo eficácia comparativamente alta com menos efeitos adversos. O presente estudo visa elucidar o perfil fitoquímico, efeitos anti-hiperlipidêmicos e antidiabéticos do extrato metanólico de D. salicifolia (folhas) em camundongos diabéticos induzidos por aloxana. Alloxan foi injetado por via intraperitoneal (150 mg kg-1, b.w), para induzir diabetes em camundongos. Os camundongos foram divididos em três grupos (n = 10). Grupo 1 (controle normal) recebeu ração normal e água purificada, Grupo II (controle diabético) recebeu ração regular e água limpa, e o grupo III (tratamento diabético) recebeu extrato metanólico da planta (300 mg kg-1) por 28 dias com uma dieta típica e água limpa durante todo o experimento. Amostras de sangue foram coletadas para verificar a glicose sérica e a concentração de LDL, TC, TG. O extrato demonstrou atividade anti-hiperglicêmica significativa (P 0,05), enquanto melhorias no peso corporal e no perfil lipídico dos camundongos foram observadas após o tratamento com o extrato. Este estudo estabelece que o extrato tem alta eficácia com comparativamente menos toxicidade e pode ser usado para o controle do DM.

Prospective Protective Effects of Arthrospira platensis Against Acetaminophen Induced Hepato-Renal Toxicity in Rats / Efectos Protectores Prospectivos de Arthrospira platnesis Contra la Toxicidad Hepatorrenal Inducida por Paracetamol en Ratas

SUMMARY: The toxic effects of acetaminophen appear primarily in the liver and kidney. The protective effect of blue green alga Arthrospira platensis on hepato-renal toxicity caused by acetaminophen was evaluated in male rats. The obtained results showed that subcutaneous injection of acetaminophen at a dose 120 &240 սl acetaminophen/kg by weight resulted in an observed elevation in the enzyme activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and Alkaline phosphatase (ALP), serum total lipids, total cholesterol, creatinine, total bilirubin, urea, nitric oxide (NO), L- malondialdehyde (MDA) and interleukins (IL-2 &IL-6). However, there is a decrease in the serum total protein, albumin and loss in antioxidant enzyme activities in liver including; superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GSH). This effect was found to be dose and time dependent. In spite of, pre- oral administration of Arthrospira platensis 1000 mg/kg .b. wt. prior acetaminophen injection succeeded to modulate the effect of the observed abnormalities caused by acetaminophen. Moreover, there were no remarkable changes in serum biomarkers of rats received Arthrospira platensis only at a dose of 1000 mg/kg by weight (group 2). The histopathological findings confirm the biochemical results that indicates the safety use of Arthrospira platensis at the selected dose in this study. Therefore, the present results clarified the protective effect of blue green alga Arthrospira platensis on oxidative stress, hepatic and nephrotoxicity induced by acetaminophen in male Wister rats.

Los efectos tóxicos del paracetamol aparecen principalmente en el hígado y el riñón. Se evaluó en ratas macho Wistar el efecto protector del alga verde azulada Arthrospira platensis sobre la toxicidad hepatorrenal causada por paracetamol. Los resultados obtenidos mostraron que la inyección subcutánea de paracetamol a dosis de 120 y 240 µl de paracetamol/kg, resultó en una elevación en las actividades enzimáticas de la aspartato aminotransferasa (AST), alanina aminotransferasa (ALT) y fosfatasa alcalina (ALP), lípidos séricos totales, colesterol total, creatinina, bilirrubina total, urea, óxido nítrico (NO), L- malondialdehído (MDA) e interleucinas (IL-2 e IL-6). Sin embargo, hay una disminución en la proteína sérica total, albúmina y pérdida en las actividades de las enzimas antioxidantes en el hígado, incluyendo; superóxido dismutasa (SOD), catalasa (CAT) y glutatión reductasa (GSH). Se encontró que este efecto era dependiente de la dosis y el tiempo. A pesar de la administración preoral de Arthrospira platensis 1000 mg/kg, la inyección previa de acetaminofeno logró modular el efecto de las anormalidades observadas causadas por el acetaminofeno. Además, no hubo cambios notables en los biomarcadores séricos de ratas que recibieron Arthrospira platensis solo a una dosis de 1000 mg/kg (Grupo 2). Los hallazgos histopatológicos confirman los resultados bioquímicos que indican la seguridad del uso de Arthrospira platensis a la dosis seleccionada en este estudio. Por lo tanto, los presentes resultados aclararon el efecto protector del alga verde azulada Arthrospira platensis sobre el estrés oxidativo, la toxicidad hepática y la nefrotoxicidad inducida por paracetamol en ratas Wistar macho.

Emergency Medical Service (EMS) Belt

Background:Emergency medical service has been a well-know n subject of discussion in India where the population is vast and the health care system is inadequate. Essential drugs are a category of drugs that are needed during the golden hour of saving a patient’s life. It becomes necessary that time, when a simple drug can save the life of a patient, a competent health care provider, is needed to administer the drug to the patient. In such a situation, any health care provider in the vicinity of the person who needs medical assistance must get an alert so that the health care provider can reach the site of the emergency and provide assistance. EMS belt is a system in which with the help of a mobile application, any person in case of a medical emergency can get service from a nearby health care provider within a few minutes. The concept is to raise an alarm alerting the nearby health care practitioners about the person in need of medical assistance. This concept is promising with the advantage that it doesn’t need any special manufacturing of the device. Conducting trials on this concept shall yield good observations and produce hopes for a cost-effective EMS system in India.

Orthopaedic Practices and Surgeries during COVID-19 in Pakistan - A Survey Based Study

@#Introduction: The study aimed to target the current practices of the orthopaedic community in outpatient (OPD), emergency (ER) and surgical services (OT) during COVID19. Material and method: This study surveyed 303 orthopaedic surgeons from all over Pakistan. The survey had 30 questions targeting the setup of outpatient, emergency and operation services in orthopaedic departments of different hospitals in Pakistan. Result: A total of 302 surgeons were included from 53 cities all over Pakistan. Between 35-48% of the respondents reported lack of availability of standard operating procedures in OPD, ER and in OT. Majority of the respondents noted that their OPD and surgical practice had been affected to some degree and 69% of the surgeons were only doing trauma surgery. This trend was higher in younger consultants of less than 45 years of age (p<0.001). Almost two-third of the surgeons, mostly senior (p=0.03) were using surgical masks as the only protective measure during various practices of OPD, ER and OT, while most of the setups were not assessing patients even for signs and symptoms of COVID. Almost 89% of the orthopaedic community is facing definite to mild stress during this pandemic and this has significantly affected the senior surgeons (p=0.01). Conclusion: Our study highlighted that COVID-19 has resulted in marked changes to the practices of the majority of Pakistani orthopaedic surgeons. Despite a sharp upsurge in the number of cases and mortality due to COVID-19, guidelines were still lacking at most of the settings and a substantial percentage of the orthopaedic community were not following adequate safety measures while attending to patients.

Population Dynamics of Intermediate-Host Snails in the White Nile River, Sudan: A Year-Round Observational Descriptive Study

We aimed to explore the population dynamics of snail in 3 sites of the White Nile in Sudan. More specifically, we aimed to investigate the annual patterns of snail populations that act as intermediate hosts of schistosomes and monthly snail infection rates and ecological characteristics presumably related to snail populations. We collected snails for 1 year monthly at 3 different shore sites in the vicinity of El Shajara along the White Nile river in Khartoum State, Sudan. In addition, we measured air and water temperatures, water turbidities, vegetation coverages, and water depths and current speeds. Most of the collected snails were Biomphalaria pfeifferi and Bulinus truncatus. The population densities of snails and their infection rates varied across survey sites. The collected snails liberated S. mansoni and S. haematobium cercariae as well as Amphistome and Echinostome cercariae. Infected snails were found during March-June. The ecological characteristics found to be associated with the absence of snails population were: high turbidity, deep water, low vegetation coverage (near absence of vegetation), high water temperature, and high current speed. To our knowledge, this is the first longitudinal study of the snail population and ecological characteristics in the main basin of the White Nile river.

Ciprofloxacin and levofloxacin adversely affect male infertility indicated by pharmacological, andrological and pathological evidence

Background: Drug-induced reproductive organs toxicities is an important aetiology in investigation of male infertility. The aim is to study levofloxacin effect on male reproductive system in comparison to ciprofloxacin.Methods: Twenty-five male wister rats weighted 230±20 gm and aged 8 weeks were randomly divided into five groups of five. The first group received ciprofloxacin with dose 78.23 mg/kg/day in 2 doses (therapeutic dose). The second group received the double dose of the first group ciprofloxacin. The third group received levofloxacin with dose 39.11 mg/kg/day once daily (OD) (therapeutic dose). The Fourth group received the double dose of the third group levofloxacin. However, the fifth group served as a control and received normal saline with carboxymethylcellulose OD. All treatments were administered orally for 14 days. On the 15th day, blood samples and reproductive organs were obtained from all rats. Testicular tissues were prepared for genetic testing and chemical and microscopical examination.Results: Ciprofloxacin and levofloxacin negatively altered reproductive organ weights, sperm parameters and serum follicle stimulating hormone (FSH) and luteinizing hormone (LH) level (p<0.05). Additionally, serum testosterone level was significantly deceased in ciprofloxacin-treated group (the double dose) (p<0.05) relative to control. The difference between ciprofloxacin and levofloxacin was significant in seminal vesicle weight and serum LH and FSH level (p<0.05). Testicular histopathological changes were also found with the two drugs with different degrees. Effects of levofloxacin and ciprofloxacin were dose-dependent.Conclusions: Both ciprofloxacin and levofloxacin adversely affect andrological function that should be monitored and controlled during application of these drugs.

Gentamicin and amikacin adversely affect male infertility indicated by pharmacological, andrological and pathological evidence

Background: Many drugs are implicated in male infertility and screening for medication history is an important for diagnosis and treatment of the problem. The aim is to study amikacin effect on male reproductive system in comparison to gentamicin.Methods: Twenty-five male wister rats weighted 220±20 gm and aged 8 weeks were randomly divided into five groups of five. The first group received gentamicin in dose 18.25 mg/kg/day once daily (OD) (therapeutic dose). The second group received gentamicin with double dose of the first group. The third group received amikacin in dose 54.75 mg/kg/day OD (therapeutic dose). The Fourth group received amikacin with double dose of the third group. However, the fifth group served as a control and received normal saline (NS) OD. All treatments were administered intraperitoneally (IP) for 14 days. On the 15th day, blood samples and reproductive organs were obtained from all animals. Testicular tissues were prepared for genetic testing and chemical and microscopical examination.Results: Amikacin and gentamicin negatively affected reproductive organs weights, sperm parameters, serum follicle stimulating hormone and luteinizing hormone (LH) level relative to control (p<0.05). However, serum testosterone level was only affected with gentamicin (p<0.05). A significant difference between gentamicin and amikacin was found in sperm count, testis and epididymis weights and serum testosterone and LH level (p<0.05). Testicular histopathological changes were also found with the two drugs with different degrees. Effects of both gentamicin and amikacin were dose-dependent.Conclusions: Both gentamicin and amikacin adversely affect andrological function that should be monitored and controlled during application of these drugs.

Could antiseptic gargling prevent COVID-19?

@#Coronavirus Disease 2019 (COVID-19) has infected more than 8 million people globally since its discovery in December 2019. For COVID-19 prevention, the World Health Organization recommended regular handwashing with soap, cough etiquette, mask wearing and social distancing. However, COVID-19 is rather difficult to contain because of its high transmissibility property. Gargling is effective for reducing infection in the respiratory tract. Most antiseptic gargles have antimicrobial properties against common respiratory pathogens. No published study on the effectiveness of antiseptic gargling among COVID-19 patients has been available to date. This article reviewed available literature on methods and solutions available for gargling and their effect on respiratory tract infections.

In vivo and in vitro Pharmacological Evaluation of Gymnosporia Royleana / Evaluación Farmacológica de Gymnosporia Royleana in vivo e in vitro

ABSTRACT Objective: Gymnosporia royleana (G royleana) Wall ex MA Lawson, locally known as (Sur Azghee), is traditionally used for the management of various diseases. In the current investigation, we made an effort to scientifically validate its traditional use in various pathological conditions, such as microbial infections and cancer, and to explore its additional pharmacological activities via random screening against locally accessible pharmacological methods, irrespective of its traditional uses like antidiabetic, haemagglutination and antioxidant assays. Methods: Extraction was carried out using a cold maceration methodology. Dilution method was used for antimicrobial susceptibility testing using different concentrations. Streptozocin (STZ) induced protocol was used to assess antidiabetic activity at a dose level of 200, 400 mg/ kg. Antioxidant activity, haemagglutination activity, and anticancer activities against HepG-2 and MCF-7 cell lines were determined as per established protocols. Similarly, the maximum amount of phenolic content (12.02 mg 100 g) was determined by using Folin Ciocalteu assay. Results: Promising antimicrobial activities in terms of minimum inhibitory concentration (MIC) were noted for crude extract (25-200 µg/mL), n-hexane (100-400 µg/mL), ethyl acetate (50-200 µg/mL) and aqueous (100-400 µg/mL). Antidiabetic potential was significant at a dose level of 200-400 mg/kg bodyweight by reducing the blood glucose level at days 10 and 15. The percentage of 2,2-diphenyl-1-picrylhydrazyl (DPPH) values increase by increasing the concentration of the plant extract (10-100 µg/mL). The methanol extract was found to possess high agglutination activity. Conclusion: It was concluded that this plant species possess significant antimicrobial, antidiabetic, antioxidant, anticancer and haemagglutination activities, which could be attributed to the phenolic content of the extract.

Conclusión: Se concluyó que esta especie de planta posee importantes actividades antimicrobianas, antidiabéticas, antioxidantes, anticancerígenas y hemaglutinantes, que podrían atribuirse al contenido fenólico del extracto.

Antibacterial and Antifungal Activities of Compounds Isolated from Gymnosporia Royleana (Celastraceae) / Actividades antibacterianas y antifúngicas de compuestos aislados de Gymnosporia Royleana (Celastraceae)

ABSTRACT Objective: In the present study, five new source compounds isolated from aerial parts of Gymnosporia royleana (G royleana) were screened for antibacterial and antifungal activities. Methods: Extraction from plant material was carried out using cold maceration technique. Isolation of pure compounds was accomplished through repeated column chromatography of different fractions obtained from crude extract and using silica gel as stationary phase. Their structures were established via advanced spectroscopic techniques along with the spectral data previously reported for these compounds. Dilution method was used for the evaluation of antimicrobial potential of the compounds against various microbial strains. Results: Among the tested compounds, Gymnosporin B displayed moderate antimicrobial activity against Escherichia Coli (E coli), Staphylococcus aureus (S aureus), Candida albicans (C albicans) and Aspergillus flavus (A flavus) [minimum inhibitory concentration (MIC) range; 32-64 μg/mL]. Similarly, Gymnosporin C also showed moderate activity against E coli and S aureus (MIC; 32 μg/mL each) as well as weak activity against C albicans and A flavus (MIC; 64 μg/mL each). However, Royaflavone showed moderate antibacterial activity against S aureus only (MIC; 32 μg/mL). Antimicrobial activity of the rest of the compounds was weak and negligible. Conclusion: The present study has provided fascinating results of antimicrobial activities of the isolated compounds. However, the broad antimicrobial spectrum of Gymnosporin B and Gymnosporin C demands for further exploration of these triterpenes, both on the basis of mechanism and quantitative structure-activity relationship.

De manera similar, Gymnosporina C también mostró actividad moderada contra E coli y S aureus (CIM; 32 μg/mL cada uno) así como débil actividad frente a C albicans y A flavus (CIM; 64 μg/mL cada uno). Sin embargo, Royaflavone mostró actividad antibacteriana moderada sólo frente a S aureus (CIM; 32 μg/mL). La actividad antimicrobiana del resto de los compuestos fue débil e insignificante. Conclusión: El presente estudio ha proporcionado resultados interesantes acerca de las actividades antimicrobianas de los compuestos aislados. Sin embargo, el amplio espectro antimicrobiano de la Gymnosporina B y la Gymnosporina C exige una mayor exploración de estos triterpenos, tanto sobre la base del mecanismo como a partir de la relación cuantitativa estructura-actividad.

In-vivo Assessment of Antipyretic and Anti-inflammatory Activities of Gymnosporia Royleana Extract in Mice / Evaluación in vivo de las Actividades Antipiréticas y Antiinflamatorias del Extracto de Gymnosporia Royleana en Ratones

ABSTRACT Objective: Despite the presence of multitude of synthetic drugs against fever and inflammation, none has been proven entirely safe. In contrast, the accepted safety of plant derived natural products is inspiring the world. Based on this fact as well as in view of the diversified activities reported from the genus Gymnosporia, the present study was designed to evaluate the antipyretic and anti-inflammatory activity of Gymnosporia royleana (G royleana). Methods: The methanolic extract of the aerial parts of G royleana was screened for in-vivo antipyretic activity using the brewer's yeast-induced pyrexia mice model and for anti-inflammatory activity using the carrageenan-induced paw oedema and xylene-induced ear oedema mice model. Results: In the antipyretic assay, G royleana extract showed considerable antipyretic activity in a dose dependent fashion. Statistically significant antipyretic effects (p < 0.05) were observed at the end of the second hour of administration for all doses of extract and remained significant until the end of the experiment. The plant extract also displayed promising anti-inflammatory activity, in a dose dependent fashion, in both models of inflammation ie carrageenan- and xylene-induced oedema models, when compared to the controls. In the carrageenan-induced oedema model, significant effects (p < 0.01) were observed for 300 and 600 mg/kg doses after 60 minutes of xylene administration (ie 55.51% and 65.88% inhibition of oedema, respectively). Conclusion: The study provided evidence supporting the antipyretic and anti-inflammatory activity of the G royleana methanolic extract.

RESUMEN Objetivo: A pesar de la presencia de multitud de fármacos sintéticos en el arsenal contra la fiebre y la inflamación, ninguno ha dado pruebas de ser completamente seguro. En contraste con ello, la seguridad aceptada de los productos naturales derivados de las plantas inspira al mundo. Sobre la base de este hecho, así como en vista de las actividades diversificadas que se reportan con respecto al género Gymnosporia, el presente estudio se diseñó con el objeto de evaluar el potencial antipirético y antiinflamatorio de Gymnosporia royleana (G royleana). Métodos: El extracto de metanol de las partes aéreas de G royleana fue tamizado en busca de actividad antipirética in vivo, utilizando el modelo de pirexia inducida por levadura de cerveza en ratones, y de actividad antiinflamatoria utilizando modelos de ratones con oedema de las patas inducido mediante carragenina, y oedema de las orejas inducido mediante xileno. Resultados: En el ensayo antipirético, el extracto de G royleana mostró una actividad antipirética considerable en forma dependiente de la dosis. Se observó un efecto antipirético estadísticamente significativo (p < 0.05) en el transcurso de la segunda hora de administración para todas las dosis de extracto y se mantuvo significativo hasta el final del experimento. El extracto de la planta también mostró una actividad antiinflamatoria prometedora, de una manera dependiente de la dosis, en ambos modelos de inflamación, es decir, modelos de oedema inducido por carragenina y xileno, en comparación con el control. En el modelo de oedema inducido por carragenina, se observó un efecto significativo (p < 0.01) para dosis de 300 y 600 mg / kg después de 60 minutos de administración de xileno (es decir, 55.51% y 65.88% de inhibición del oedema, respectivamente). Conclusión: El estudio proporcionó pruebas suficientes sobre el potencial antipirético y antiinflamatorio del extracto de G royleana.

The effects of diet and temperature on enzymes, hormones, and fecundity of the African Catfish Clarias gariepinus (Burchell 1822)

The aim of this study was to check the effect of multiple temperatures and various protein diet formulas on liverenzymes, gonadotropins, and growth hormone (GH) using African catfish Clarias gariepinus. C. gariepinus wasexposed to multiple temperatures (T24°C, T28°C, and T32°C) and various protein diet formulas: D1 (fishmeal-baseddiet), D2 (soymeal-based diet), and D3 (pea-meal based diet). Tilapia commercial feed (D4) was used as reference diet.A total of 720 individuals with an average weight (101–104 g) were stocked at a density of 20 individual fish per tankin 12 tanks of three replicates. Liver enzymes, gonadotropins, GH, and fish fecundity were measured after 16 weeks.The results revealed that liver enzyme like glutamate-oxaloacetate transaminase was significantly (P < 0.05)lowered at T28°C: D2 diet, while glutamic pyruvic acid transaminase was lowered by T28°C: D4 diet. However,no effect was observed on creatinine (P > 0.05) at any experimental condition. Follicle-stimulating hormone andluteinizing hormone were significantly (P < 0.05) increased at T28°C: D1 diet and T32°C: D1 diet, respectively. GH wassignificantly (P < 0.05) increased by T28°C: D1. The relative weight of the ovary of C. gariepinus was significantly (P< 0.05) increase at T32°C: D1, while the testis relative weight was increased with T24°C: D3. The result from this studyrevealed that there is a direct relationship of temperature on fish fecundity, enzymes, and reproductive hormonesin C. gariepinus. The temperature of 28°C along with fishmeal or soy-meal positively improved the fecundity andhealth of fish.

An Investigation of the Prevalence and Causes of Malnutrition in Iran: a Review Article and Meta-analysis

Malnutrition is one of the most important health issues in developing countries, which might have adverse effects on the physical and intellectual health of children. The search process was started to find Persian and English articles published until September 2017 regarding the prevalence of malnutrition in children under the age of six in Iran using national and international databases including SID, Magiran, Irandoc, IranMedex, PubMed, Medline, Scopus, and ISI Web of Science. The data were analyzed using meta-analysis methods and the random effects model. The heterogeneity of studies was analyzed using the I² index. The data were analyzed using R and STATA software (ver. 11.2). Twenty seven articles conducted from 2002 to 2016 were collected to be included in the meta-analysis process. The total sample size was 161,941 patients in an age range of 0-6 years. The final estimate of the prevalence of different forms of malnutrition through meta-analysis of data extracted from studies in Iran was as follows: severe underweight (1%; 95% confidence interval [CI], 1–1), moderate underweight (6%; 95% CI, 5–7), mild underweight (25%; 95% CI, 21–28), severe short stature (3%; 95% CI, 2–3), moderate short stature (8%; 95% CI, 6–9), mild short stature (21%; 95% CI, 17–24), severe slimness (1%; 95% CI, 1–1), moderate slimness (5%; 95% CI, 4–5) and mild slimness (20%; 95% CI, 17–24). Considering that the prevalence of malnutrition is relatively high in Iran, health authorities should plan to improve the nutritional status of children.

Amoxicillin–clavulanic acid induced sperm abnormalities and histopathological changes in mice

Objective To explore the genotoxic potential and histopathological changes induced in liver, kidney, testis, brain and heart after using the antibiotic drug amoxicillin/clavulanic acid (4:1). Methods The study included chromosomal aberration analysis in bone-marrow and mouse spermatocytes, induction of sperm morphological abnormalities and histopathological changes in different body organs. The drug was administrated orally at a dose of 81 mg/kg body weight twice daily (Total = 162 mg/kg/day) for various periods of time equivalent to 625 mg/men (twice daily). Results The results revealed non-significant chromosomal aberrations induced after treatment with amoxicillin/clavulanic acid (AC) in both bone marrow and mouse spermatocytes after 7 and 10 days treatment. On the other hand, statistically significant percentages of sperm morphological abnormalities were recorded. Such percentage reached 8.10 ± 0.55, 9.86 ± 0.63 and 12.12 ± 0.58 at the three time intervals tested (7, 14 and 35 days after the 1st treatment respectively) (treatment performed for 5 successive days) compared with 2.78 ± 0.48 for the control. The results also revealed histopathological changes in different body organs after AC treatment which increased with the prolongation of the period of therapy. Congestion of central vain, liver hemorrhage and hydropic changes in hepatocytes were noticed in the liver. Degenerative changes were found in kidney glomerulus and tubules while testis showed atrophy of seminiferous tubules, and reduction of spermatogenesis. AC also induced neurotoxicity and altered brain neurotransmitter levels. Hemorrhage in the myocardium, disruption of cardiac muscle fibers and pyknotic nuclei in cardiomyocytes were recorded as side effects of AC in heart tissue. Conclusions The results concluded that AC treatment induced sperm morphological abnormalities and histopathological changes in different body organs. Clinicians must be aware of such results while describing the drug.

Innovation in chemotherapy administration process.

INTRODUCTION: This project was started after patient’s complaints of increased cost burden on patients with increase stay of patient in hospital for chemotherapy administration for 3–4 days, how to decrease this hospital stay and financial burden and how can we improve services to decrease hospital stay and expedite the process of chemotherapy administration. METHODS: A total of 100 patients’ confidential files reviewed from February 12, 2013 to May 15, 2013, patients, who were admitted for chemotherapy administration only in inpatient area and all services timings, were reviewed and documented on sheet named as delays chemotherapy sheet, nine processes timings checked against their benchmarks. RESULTS: All services process timings analyzed and compared with their benchmarks, results of all services timings are nearly close to benchmark except lab test results of patients who were admitted without labs test for chemotherapy administration delays seen in collecting blood sample and sending this sample to the laboratory, significant delay is seen in chemotherapy order entry by physician if patient is admitted after 4 p.m. for chemotherapy administration. Delays also identified in administration of chemotherapy. CONCLUSION: After identifying the reasons of delays in chemotherapy administration, improvement and innovation in chemotherapy administration process done which not only decrease hospital stay, but also decrease the cost of chemotherapy administration.

The Effect of Bone Marrow Mononuclear Cells on Lung Regeneration and Apoptosis in a Simple Model of Pulmonary Emphysema

BACKGROUND: In severe chronic stages of emphysema the only treatment is lung transplantation. SO, an urgent need exists for the development of effective treatments. Stem cells therapy arises as a new therapeutic approach. AIM OF THE WORK: To investigate whether bone marrow mononuclar cells (BMMNCs) can promote lung regeneration and decrease apoptosis in lipopolysaccharide (LPS) induced pulmonary emphysema in C57Bl/6 mice. MATERIAL AND METHODS: 14 weeks old female mice (C57Bl/6), weighing around 25 g were used in this study. The mice were divided into 4 groups (10 in each group): group A: mice received no treatment, group B: mice received intranasal instillation of LPS with no further treatment, group C: mice received intranasal instillation of LPS then given a dose of BMMNCs and evaluated 21 days later and group D: the mice that received intranasal instillation of LPS then given a dose of Dulbecco's Modified Eagle's Medium (DMEM) and evaluated 21 days later. Imaging analysis was done using imagej program. To measure apoptotic index, Anti-caspase 3 polyclonal antibody staining was done. RESULTS: Analysis of the mean of airspace equivalent diameters (D0) and its statistical distribution (D1) for the different groups allowed to observe that group treated with BMMNCs (group C) showed the significant improvement in D0 and D1 than the group received LPS only (group B). Analysis of apoptotic index showed significant difference between BMMNCs treated group (group C) and that received LPS only (group B). CONCLUSIONS: BMMNCs effectively promote lung regeneration and reduction of apoptosis in pulmonary emphysema.
