Background: Prosopis fracta is a valuable and useful medicinal plant for the purpose of extracting flavonoids and it is one of the most important plants with medicinal properties. Prosopis fracta is found in many southern regions of Iran. Objective: the aim of this review Phytochemistry and biological activity of Prosopis fracta. Material and Methods: Initially, the powder was degreased by hexane and then after completion of the extraction process, we obtained a rotary solvent removal and the rest of the extract was frozen for retention, then it stored at -23°C. The freeze-dried samples are dissolved in methanol and permanently filtered through a 0.35 syringe filter. Results: Prosopis fracta extracts using to treat cancer, which destroying activity via mitochondrial changes, as showed a good example for increased reactive oxygen species (ROS) levels, SIRT3 activity and cell death in HT-29 related to the intestines and rectum cancer cells. Conclusion: Antimicrobial and phytochemical studies provide valuable insight into understanding media. Sometimes the idea of the route responsible for the activity of these phytochemicals against oxidizing compounds that act as a source of harmful chemical to the body is removal from service of protein and loss of function.

Background: medicinal plants are abundant in phytochemicals, which represent the richest bioresource of drugs are used against various diseases. Objective: The present study included an in-vitro antimicrobial investigation for one of wild Iraqi plant Lepidium draba on some skin infectious agents. Methods: The fresh aerial plant parts were macerated in 80% ethanol and subjected to phytochemical general test to investigate the plant active contents. Totat flavonoids were isolated through plant reflex in acidic aqeous solution to obtain the aglycone flavonoids using ethylacetate as an organic solvent. Qualification and quantification of the isolated total flavonoids were done in coressponding to standard s flavonoids. An antimicrobial activity for the crud ethanolic extract and the isolated total flavonoids had been carried out on some skin infectous agents using the following strain: Staph aureus, Pseudomoneus aerogenosa  and Candida albicans. Results: the outcome showed that the plant contain major active constituent included flavonoids Tannins, polysaccharides, alkaloids,saponines and Polyphenolic compounds.The plant contains many types of flavonoids including Rutin, Qurecetin, Kampferol and Luteolin, and each 100 g fresh aerial parts will contain 28 mg total flavonoids. The amount of each type of flavonoids were detected by HPLC technique. the extracted flavonoids at concentation of 4mg/ml showed potent effect upon the gram bacteria  negative pseudomonas aeruginosa  which is known to be more virulence than the gram positive strains but has no effect on Staphylococcus aureus. Also the extracted flavonoids appeared to be  affected against  the Candida albicans growth. Conclusion: the ethanolic extractv of  locally plant L.draba is effecient to inhibit the growth of pathogenic bacteria and decrease the chances of skin infection  that provided the justification for therapeutic potential as supplementary or alternative medicine.

Background: Obesity and type 2 diabetes have both rapidly raised during the last periods and are ongoing to increase at a disturbing rate universal. Several clinical and epidemiological researches demonstrated a reverse association between circulating vitamin D levels, central adiposity and the progress of insulin resistance and diabetes. Objective: The target of this work was to elucidate the complex role of vitamin D and the clinical implications of diabetes on metabolic defects related with obesity. Subjects and Methods: This study encompassed 90 diabetic patients (45 obese and 45 non obese) who were attending the National Diabetic Center/ Al-Mustansiriyah University during the period from June 2019 to January 2020; their age range was (35-60) years. All participant underwent clinical and biochemical examinations. Results: A substantial rise (p= 0.01) in waist/hip ratio, body mass index, fasting serum glucose, total cholesterol, triacylglycerol, and low density lipoprotein cholesterol in obese diabetic patients as paralleled to non-obese group. Moreover, there was an elevation in glycated hemoglobin, serum insulin, and homeostasis model assessment for insulin resistance in obese group, but it was not significant. A substantial decrease (p= 0.01) in serum high density lipoprotein cholesterol and vitamin D3 were detected in obese diabetic patients as paralleled to non-obese group.       Also, obese diabetic patients had the higher percent (61%) of D3 deficiency as paralleled to non-obese patients. Conclusions: In the present study, it is found that there is significant increase in blood sugar in the individuals with decreased vitamin D levels, which was related with insulin resistance, decreased β-cell function, and obesity.  
背景:肥胖和2型糖尿病在过去一段时间内迅速增加,并且正在以令人不安的速度持续增加。一些临床和流行病学研究表明,循环维生素D水平、中枢性肥胖和胰岛素抵抗和糖尿病的进展之间存在反向关联。目的:阐明维生素D在肥胖相关代谢缺陷中的复杂作用及糖尿病的临床意义。受试者和方法:本研究纳入了2019年6月至2020年1月期间在国家糖尿病中心/ Al-Mustansiriyah大学就诊的90例糖尿病患者(45例肥胖和45例非肥胖);年龄在(35-60)岁之间。所有的参与者都进行了临床和生化检查。结果:肥胖糖尿病患者腰臀比、体重指数、空腹血糖、总胆固醇、甘油三酯、低密度脂蛋白胆固醇与非肥胖组相比均显著升高(p= 0.01)。此外,肥胖组糖化血红蛋白、血清胰岛素和胰岛素抵抗稳态模型评估均升高,但不显著。与非肥胖组相比,肥胖糖尿病患者血清高密度脂蛋白、胆固醇和维生素D3显著降低(p= 0.01)。此外,与非肥胖患者相比,肥胖糖尿病患者D3缺乏症的比例(61%)更高。结论:本研究发现维生素D水平降低的个体血糖明显升高,这与胰岛素抵抗、β细胞功能下降、肥胖有关。

Background: The microbial production of substances that have the potency to suppress the growth of other microorganisms is probably one of the prevalent defense strategy developed in nature, microorganisms produce a variable bunch of microbial defense systems, which include antibiotics, metabolic by-products, lytic agents, bacteriocins and others. Objective: The purpose of the present study was to isolate and identify Enterococcus faecium isolates then detecting its ability of carrying the gene responsible for enterocin production in this species. Materials and methods: Out of 50 samples from different sources (food and clinical sources) were collected for the Enterococcus faecium isolation, and the isolated bacteria Enterococcus faecium (37) isolates were detected for their harboring of Enterocin A gene (entA), using conventional PCR technique. Results: The identification revealed that 37(74%) isolates were considered as Enterococcus faecium, 20 isolates (54.05%) out of food samples (10 samples were collected from dairies, 7 from vegetables and 3 from fish samples), and 17 isolates 45.9% out of clinical samples (11 from stool and 6 from urine source). Genotypic Detection done by the amplification of the enterocin coding gene (ent A),  and the results revealed that all the isolates were harboring that gene despite of the phonotypical differences, that they amplified entA gene and the PCR product size (362 bp) was detected using agarose gel electrophoresis. Conclusions: This study indicates the presence of Enterococcus spp. in food and clinical sources and the ability of these bacteria to produce antibacterial substances which is active against closely related clinical isolates.

Background:The most important medical challenge is the emergence of bacterial resistant to traditional antibiotics. So the need for new pharmaceutical compound derived from daily intake plant material. Mint and black tea used extensively in Arabic area as hot or cold drink Objective: investigate the bacterial activity of mint and black tea aqueous extract against many bacterial genera. Material and methods: from the local market of Baghdad Province, Iraq, dry black tea was obtained; while, peppermint (Mentha piperita L) was harvested from Iraqi plants during April 2020. Active ingredients extracted using either ethanol or water and their antibacterial activity evaluated against Staphylococcus aureus, S.epidermidis, Citrobacter sp and Klebsiella sp using well diffusion agar under invitro laboratory condition.  Results: Dried powder of each extract appeared with different color range from brown to black. Results recognized that S. aureus was susceptible to watery and ethanolic extract of both black tea and peppermint extracts. While, S. epidermidis showed resist to both plant extract and solvents used in extraction except minor inhibition with ethanolic extract of tea at 0.3% dose dose. Citrobacter spp gave susceptibility to watery extract of black tea as well as, watery and ethanolic of mint extract. Otherwise, Klebsiella spp. Growth inhibited by watery extract of black tea while, no bioactivity existed upon mint extract treatment. Conclusion: Dose dependent manner existed for watery and ethanolic extracts for both plant material in their antibacterial activity.
