Burn wound infection is a major complication in burn patients after initial period of shock. More than 70 % mortality in burn patients is attributed to infection. This study was conducted from July 2008 to February 2009 at Teiba Center for Burns Surgery in Al-Jumhory Hospital located in Sana'a city, Yemen. A total of 200 burn wound swab were collected. Fifty eight (58%) of patients were males and forty two (42%) were females. The most common age group was ≤ 10 years group (42%), (84.5%) had second-degree burns, (13%) had third-degree burns, (1.5%) had fourthdegree burns and the remainder had first-degree burns, (69.5%) were due to flame, (24.5%) were due to scalds, (4.5%) cases were due to electrical burns and three cases were due to chemical burns. Out of 167 positive cultures, single Gram positive bacteria were the most dominant (44.3%), followed by Gram negative bacteria (28.7%) and mixed Gram positive and Gram negative bacteria (20.4%). Staphylococcus aureus was the most common organism, isolated 100 (47.8%), followed by Pseudomonas aeruginosa (23%), Candida albicans (5.3%), Escherichia coli (5.3%), Serratia plymuthica (3.8%), Proteus mirabilis (2.9%), Salmonella species (2.4%), Staphylococcus epidermidis (2.4%), Acinetobacter species (1.9%), Streptococcus faecalis (1.4%), Bacillus species (0.96%), Citrobacter freundii (0.96%), Klebsiella species (0.96), and Streptococcus pyogenes (0.96%).
COVID-19 is an emerging infectious disease caused by the novel enveloped single-stranded RNA virus quickly declared a pandemic. This study aimed to investigate the severity of COVID-19 infection in patients with blood group type A. A cross-sectional study was conducted at Al-Amal specialized hospital, Al-Najaf (March 8 to March 20/2021). The study included 123 hospitalized patients (63 females and 60 males), aged between 15-95 years, diagnosed with COVID-19, tested for blood group, blood sugar, blood urea, D-dimer, and serum ferritin. Results indicated significant differences in blood sugar and D-dimer in patients with type A blood group at P>0.05. At the same time, no significant difference was found in blood urea and ferritin at P>0.05. The majority of patients showed elevated levels of blood sugar, blood urea, serum D-dimer and ferritin. COVID-19 can infect people of all ages and causes severe infection in all blood groups.
The aim: The study carried out to determine the effect of the Calcium Oxide Nano Particles on the male rats. In this study were used calcium oxide nano powder to enhancing apoptosis in germ cells and disrupting hormonal regulation of reproductive processes in the adult male rats.
Materials and methods: The experiment using nine male rats, were distributed into three groups. Group one A was doses orally of Calcium Oxide Nano Particles 50 mg/kg of body weight, while group two B was doses orally of Calcium Oxide Nano Particles 100 mg/kg of body weight; also, group three C were a control C group treated with 0.9% saline only, these orally doses continuous 10 days. After 10 days blood samples collected and all rats were euthanatized and the weights, histological changes and hormonal analysis were conducted.
Results: Results show a significantly increased at p<0.05 for both groups A & B compare with control C in weight of testis tissue and the level of testosterone hormone, also histology changes in testis of treatment rats include: necrosis of spermatogonia, primary spermoocyte and spermatids in both groups compared to control group.
Conclusions: Through the study, it is recommended to use medium or low doses of CaO NPs that can be used as a testicular tonic and urge it to increase production of the Testosterone hormone.
The study was done in Al- Najaf Health Department \ Alforat Al-Awsat Hospital. The total number of examined patients were (80) for both sexes (males and females) in different ages (children’s and adults). The chosen patients had single infection with Entamoeba histolytica was diagnosed in 32(40%) stool samples from the total number examined. The results showed no significant differences between males (40%) and females (40%) in tested with parasites. The samples were recorded the average percentage in the cyst stages of E. histolytica at a higher rate, where it reached (87.5%) than the trophozoite stage of E. histolytica, where it reached (12.5%). There were significant differences at the level of p <0.05 when studying the effect of E. histolytica parasite in both stages (cyst and trophozoite) in some blood parameters (PCV, Lymphocyte, Granulocyte and Platelets count). Also, results showed a significant differences only in the cyst stage in (MCV, MCH and Monocyte) and there were no significant differences in the other blood parameters (Hb, WBC, RBCand MCHC) among the infected and non-infected person with E.histolytica parasite.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
