Summary:
Background: the immune system differentiates between the endogenous and exogenous bodies that inter the body. The break-down of blood-testis barrier results in the production of antisperm antibodies. This may occur in the case of an infection to the prostate, seminal vesicle and epididymes. Antisperm antibodies (ASA) cause sperm agglutination and affect sperm motility, viability and sperm migration in the female reproductive tract. ASA also impair fertilization process. The objective of the present work was to study the effect of prednisolone on sperm motility index (SMI), viability and sperm penetration assay (SPA) in immunologically infertile men.
Materials and methods: The semen and serum samples of 140 infertile men were examined by microagglutination test and slide agglutination test to detect ASA and sperm agglutination. Semen fliud analysis was performed to report sperm motility index (SMI), sperm viability and hypo-osmotic swelling test (HOST). Sperm penetration assay was done to record sperm penetration rate (SPR), sperm decondensation rate (SDR) and sperm penetration index (SPI). Men with positive ASA were treated with prednisolone and considered as treated group Prednisolone was given orally in a dose of 5 mg three times daily for three months. The semen analysis, SMI HOST and SPA were performed before and after treatment with prednisolone. The number of semen samples in the treated group was 144 and in the control fertile group was 80. HOST-SPA positive semen was exposed to antisperm antibodies separation (ASAS) and invitro sperm activation prior to intra-uterine insemination.
Results: The SMI was significantly higher in the post-treated group compared to pretreated group (240 vs. 52.5, P<0.0l). The SPI in the control group was significantly higher than the post and pre-treated groups. The HOST and viability test results were significantly increased in the post-treated group compared to pre-treated group (73.42 vs. 48.56 and 71.36 vs, 50. 74 respectively, P<0.01). The sperm penetration rate, sperm decondensation rate and sperm penetration index were significantly increased in the post-treated vs. pre-treated groups (26.49 vs. 10.84, 10.91 vs. 3.47, P<0.05, 14.45 vs. 4.30, P<0.01 respectively). HOST-SPA positive semen was used for intra-uterine insemination (IUI). The semen was exposed to ASAS and in vitro activation prior to IUI and resulted in 42.86% pregnancy rate per cycle. The pregnancy was confirmed by the observation of gestation sac and viable fetal hear beet 5 weeks following IUI.
Conclusion: It was concluded from the results of the present study that treatment of immunological infertile men with prednisolone improves SMI, sperm viability and SPA results. The application of HOST-SPA positive semen for IUI resulted in successful pregnancy. The authors indicate that these viable spermatozoa with high fertilizable potential could be used for IVF and/or ICSI in immunologically infertile men.
The current study aims to test the impact of green training and development on sustainable performance and explore its effects within and outside the Iraqi Ministry of Environment. The main research problem revolves around the question of the extent of implementing green training and development and sustainable performance in the ministry (What is the nature of the relationship between green training and development and sustainable performance in the ministry?). To clarify the relationship between the research variables, two main hypotheses were formulated along with sub-hypotheses. The study also aims to assess the level of the ministry's interest in the research variables and provide key recommendations to enhance sustainable performan

The experiment was conducted to study the effect of leaves extract of Salvia sclarea , Rosmarinus officinalis and Thymus vulgaris with 10% and 30% concentration on germination of seeds and growth of seedlings . The effect of these extracts on infection percentage of seeds decay and surface growth of Rhizoctonia solani . The results showed that the three extracts effected significantly to reduced percentage of seeds germination, acceleration of germination , promoter indicator , infection percentage of seeds decay and surface growth of R. solani especially in 30% concentration .
In this work, the effect of ceramic coating on performance, exhaust gas temperature and gases emissions of diesel engine operated on diesel fuel and biodiesel blends was investigated. A conventional four stroke, direct injected, single cylinder, diesel engine was tested at constant speed and at different load conditions using diesel fuel and biodiesel blends. The inlet and exhaust valves, the head of piston and cylinder head of the engine were coated by ceramic materials. Ceramic layers were made of (210-240) μm of Al2O3 and (30-60) μm of 4NiCr5Al as a bond coat for inlet and exhaust valves and (350-400) μm of YSZ and (50-100) μm of 4NiCr5Al as a bond coat for head of piston and (280-320) μm of Sic and (40-80) μm of 4NiCr5Al as a b

... Show MoreThe Fauqi field is located about 50Km North-East Amara town in Missan providence in Iraq. Fauqi field has 1,640 MMbbl STOIIP, which lies partly in Iran. Oil is produced from both Mishrif and Asmari zones. Geologically, the Fauqi anticline straddles the Iraqi/Iranian border and is most probably segmented by several faults. There are several reasons leading to drilling horizontal wells rather than vertical wells. The most important parameter is increasing oil recovery, particularly from thin or tight reservoir permeability. The Fauqi oil field is regarded as a giant field with approximately more than 1 billion barrels of proven reserves, but it has recently experienced low production rate problems in many of its existing wells.
