This investigation assess the water quality of ten selected hand-dug wells which for sometimes serve as alternative sources of drinking water of the Wuntin Dada inhabitants due to inadequate public supply of potable water. Water from each of the selected hand-dug wells was sampled in a sterilized 500ml plastic container and taken to the laboratory for analysis. Samples were analysed for physical, chemical and microbial parameters. Physical parameters analysed include; pH, Temperature, Turbidity, Electrical Conductivity and Total Dissolved Solids. The mean values of all the physical parameters are within the standards set by the Nigerian Industrial Standard (NIS) as stipulated in the Nigerian Standards for Drinking Water Quality (NSDWQ) guidelines. Waters from the water sources investigated are therefore safe as far as the physical quality is concerned. Chemical parameters analysed include; Sodium, Calcium, Magnesium, Iron, Lead, and Arsenic. Calcium and Magnesium concentrations are the only two parameters with concentrations higher than the maximum permissible levels set by the Nigerian Standard for Drinking Water Quality (NSDWQ). Calcium mean value is 184mg/l against the maximum permissible level (mpl) of 75mg/l while that of Magnesium is 70mg/l against the maximum permissible level (mpl) of 20mg/l. The rest are within the maximum permissible levels set by the Nigerian Industrial Standard (NIS), 2015 standards for drinking water quality. Total hardness is generally high in all the samples with range value of 154 -255mg/l. The water sources investigated provide the inhabitant with hard water. The mean value for Faecal Coliform is 1.6cfu/100ml against the maximum permissible level of 0.00cfu/100ml was rather alarming. This is an indication that the water sources under investigation were recently contaminated and may contain pathogens responsible for water borne diseases. Periodic disinfection of the water sources is highly recommended.

Validation of the Ethylene Oxide Sterilization of Polypropylene Disposable Syringes
Mohammed E.I, M.S.; M.E. Osman, Mohammed
The current study describes the efficiency of the sterilization method by mixture of 30% ethylene oxide and 70% CO2 gas in a single cylinder its capacity 25 kg for single-use polypropylene syringes. The sterilization process was performed within six hours at 53°C to 54°C, pressure of 1320 ml bar and relative humidity of 60%. The chemical and biological indicators were removed from the cartons after completing the sterilization process. The results of the chemical test gave a change in the color of the chemical indicators tape which adhesive on the surface of each carton from yellow to orange. The chemical indicators strips which are packaged with the syringes changed from red to green that means indication of the sterilization process successfully. The result of the biological indicators (a bacterium called Bacillus atrophaeus placed in special tubes in prepared conditions containing special food). The biological indicators placed for 48 hours on a special instrument containing an incubator and an ultraviolet light bulb to detect the presence of bacteria. The instrument gave a negative result (green light) to indicate the absence of bacteria or bacterial growth and this indicated the success of the sterilization process and the efficiency of sterilization method by ethylene oxide gas effective for medical products, especially for medical syringes.

Human semen contains high concentrations of Zinc (Zn) inbound and ionic forms. The presence of abnormal levels of Zinc and testosterone may affect spermatogenesis production, maturation, motility, and fertilizing capacity of the spermatozoa.
This study aimed to evaluate the levels of Zn in seminal plasma and serum and also to assess the serum testosterone concentration in different groups of males with infertility and to correlate their concentrations with sperm counts.
Association of Serum and Seminal Plasma Zinc Levels and Serum Testosterone Concentration in Oligospermic and Azospermic Infertile Menstudy conducted in Khartoum state. The study carried out from March to August 2017. Hundred fertile and infertile males, 35 from them, were oligospermic,35 were azoospermic, and 30 males were normospermic. The serum testosterone was estimated using Tosoh 360, while the atomic absorption spectrophotometer determined the Zinc concentration in separated seminal plasma of each infertile male and fertile control subject. The data were analyzed using SPSS version 25.
The age ranged from (18 to 40 years) with their average age was 29.11 ± 5.49 years. The serum testosterone was significantly lower (p<0.001) in azoospermic male compared with normospermic male and also serum and plasma seminal Zinc were highly significantly lower in azoospermic and oligospermic males compared with normospermic male (p=0.000). Positive correlation between seminal plasma and serum levels of Zinc and sperm count respectively, (r= 0.935, P=0.000), (r= +0.824, P=0.000), and also there was negative correlation between serum testosterone and sperm count (r= -0.133,(P≤ 0.447).
In this study, the serum and seminal plasma zinc level was significantly decreased in azoospermia and oligospermia and were correlated with sperm counts and also serum testosterone was significantly decreased in azoospermia and was negatively correlated with sperm counts. It indicates that Zinc has a possible role in spermatogenesis and zinc plasma seminal considered one of the factors of testicular function in male subjects.

Association of Factors Affecting Job Satisfaction Among Critical Care Nurses at Khartoum Governmental Hospitals - Sudan

Job satisfaction among nurses was significant issue in any health organization to provide a high quality of care and best patient’s outcomes promotes effective coronary and intensive care management as well as safe patient care. The objective is to determine association between factors affecting job satisfaction and job satisfaction regarding nurses working in intensive care unit (ICU) and coronary care unit (CCU) in governmental hospitals in Khartoum State in six governmental hospitals in Khartoum State, includes Khartoum teaching hospital, Elsheeb teaching hospital ,Bahri teaching hospital, National Center for Medical and Surgical of Nervous System, Ahmed gassum teaching hospital ,Omdurman teaching hospital and chinaness friend ships hospital.The ability to express concerns some factors were significantly associated with job satisfaction. However there was astronge relationship between the job satisfaction, work environment, enough payment and scheduling. Descriptive cross-sectional total coverage hospital based study, included105 nurses working in ICU and CCU as participants. A standardised structured self-administered questionnaire was used to collect data that consisted of two domains, the first domain contained the demographic data and second domain contained the factors affecting nursing job satisfaction, including information about the nurses’ work environment, enough payment and supervisor.Data was analysed by the computerized method Statistical Package for Social Sciences (SPSS) Version 20. The results provided tentative support for distinguishing between extrinsic and intrinsic sources of job satisfaction. One component explained intrinsic work factors (mainly the job itself factor, but also the promotion factors), while the other four components accounted for extrinsic work factors, namely, dissatisfaction with: working conditions, payment, and supervisor. Difference in nurse satisfaction was significant (p value 0.05). That means enough payment affects nurse job satisfaction. Association found between nursing work under stress, payment, supervisor and promotion. There was remarkable found to be demonstrated significantly related nurses job satisfaction and those factors, work under stress, payment and supervisor.
