Abstract

Antimicrobial activity of secondary metabolites that produced by Lactobacillus spp. has been investigated against clinical isolate of Staphylococcus aureus.Acidity effect of anaerobic fermentation of lactose in raw milk to lactic acid by Lactobacillus spp. was studied. The accumulation of acid in the medium lead to lowering pH of the yoghurt that prevent growth of Staph. aureus. The ability of clinical isolate was experimented for survival in acidic, alkaline, and neutralpH, the results showed that Staph. aureus have no growth in acidic pH while they have heavy growth in neutral and alkaline pH.This study confirmed the presence of synergistic effect between the secondary metabolites of lactobacilli and the acidity in yoghurt, which lead to inhibitory effect on the growth of Staph. aureus.

Abstract

background: Since the discovery of the roentgen ray in 1895, radiography and fluoroscopy remained the stanchion of diagnostic radiology for decades. During fluoroscopy procedures the radiation exposure of staff arises due to scattered radiation. The adequacy of shielding for secondary radiation depends on the material and thickness used for this purpose.Aim of the study: This work studies the secondary shielding for the control booth of fluoroscopy room in AL –Hussaine teaching hospital of Karbala city, Iraq.Materials and method: By considering the fluoroscopy room design and the radiographic devices profiles used, the clinical total workload per week and total workload per patient have been computed and its distribution according to the most widely used voltages has been determined by recording the actual clinical technical values of maximum ,average and minimum As and the corresponding values of kilovolt peak for 217 patients over five months. As a diagnostic x-ray radiation shielding reference, the National Council on Radiation Protection and Measurements report No.147 (NCRP report No.147) and XRAYBARR computer program have been used to compute the secondarybarrier thicknesses of the control booth of the fluoroscopy room for lead and glass.Results and discussion: It is found that the total workload per week of NCRP report No.147 is about equal that of calculated for average state and about 1.6 times that of calculated workload for busy state.Conclusion: The shielding status of control both was quite sufficient ,and about 1 mm of lead was used to shield the front wall and lead glass was used in the shielding of observation window

Abstract

Aims:To investigate the efficacy of dried gamma-irradiated amniotic membrane dressing for the healing of full-thickness skin wounds, using a rabbit model. Materials and Methods: This study was performed in the Oral and Maxillofacial sugery Department, College of Dentistry, University of Mosul, Iraq. Twenty, locally bred, six to eight months old male rabbits were planned to conduct the study. Bilateral full-thickness circular segments approximately 10 mm in diameter and nearly (3-4)mm in thickness were excised from the the back of each rabbit ( near to the mid-dorsum area) with a surgical blade; one dorsal skin wounding was performed lateral to the midline on right side, the other wound was performed lateral to the midline on left side. The right wound was used as an experimental wound and covered with dried amniotic membrane whereas the left wound was considered as a control wound. All wounds were covered with non adherent moist occlusive gauze. Animals were divided into four groups according to sacrificing date ( 3, 7, 14, 30) days. Skin specimens were collected after sacrificing the rabbits. The specimens were placed in formaldehyde and sent for histopathological examination and scoring for wound healing. Results: The histopathological findings of this study revealed that there was a significant difference of reepithelialization between the two groups at two weeks period, at p-value < 0.05, while there was no significant difference at 3 days, one week, and one month. Conclusions: This study concluded that amniotic membrane can be used as a safe dressing, promoting epithelialization on secondary wounds.

Abstract

Let M be a non-zero right module over a ring R with an identity. The weakly secondary submodule is introduced in this paper. A non-zero submodule N of M is weakly secondary submodule when Nab⊆K, where a, b∈R and K is a submodule of M implies either Na⊆K or Nb^t⊆ K for some positive integer t. Some relationships between this class of modules and other related modules are discussed and number of conclusions and characterizations are obtained.

Abstract

ABSTRACT
Objective: To highlight the importance of laparoscopic evaluation in the etiology of infertility and to evaluate the etiology in primary and secondary infertility.
Methods: This retrospective study included 1233 patients complaining of infertility, 919 patients had primary infertility and 314 patients had secondary infertility. All had been subjected to diagnostic laparoscopy at the Infertility Center in Al-Batool Teaching Hospital, Mosul.
Results: Laparoscopy diagnosed pelvic abnormality in 87.27% of infertile patients which was statistically significant difference comparing to no abnormality detected in 12.73%. The ratio of positive findings in secondary infertility was significant in comparison with the positive findings in primary infertility. Single pelvic abnormality detected during laparoscopy among infertility patients was seen in 75.09% of cases and it was statistically different from multiple pelvic abnormality: 24.91%, and it was highly significant among primary infertility patients (77.24%) and among secondary infertility patients (30.87%). Among all infertile patients, ovarian factor was the most common (66.83%) followed by tubal factor (22.03%), endometriosis (4.46%), pelvic inflammatory disease (2.85%), pelvic adhesion (2.10%) and uterine fibroid (1.73%). Ovarian factor was highly significant in primary infertility while tubal factor and pelvic inflammatory disease were the highly significant in secondary infertility.
Multiple pelvic pathology identified by laparoscopy showed the tubal factors associated with poly cystic ovary in 29.49% of cases (31.66% in primary infertility and 25% in secondary infertility with no significant statistical difference). Pelvic inflammatory disease associated with other pelvic abnormality 34.09% was highly significant among secondary infertility patients. Congenital uterine abnormalities was not seen alone, it was seen associated with other causes among primary infertility patients (9 cases 0.72%).
Conclusion: Diagnostic laparoscopy is a valuable technique and is a mandatory invasive investigation for complete assessment of female infertility before the couple progresses to infertility treatment especially where assisted reproductive techniques were not available.
Keywords: Infertility; primary infertility; secondary infertility; diagnostic laparoscopy.
