Effect of Some Heavy Metal Ion on the Efficiency of Some Natural Dyes Solar Cells with Titanium Dioxide
Authors: Matter Hamdy AB. , Ayad Tariq M. 
Published: December 2023

Solar cells were made from natural pigments such as the anthocyanin pigment extracted from berry juice, henna leaves and roselle, betalain dye extracted from beets and red cabbage, and yellow curcumin dye extracted from turmeric with titanium dioxide. The ions of some metals are used with some dyes in the formation of cell electrodes with titanium oxide and zinc oxide. The mixture is heated to 450 ºC and makes electrodes that have a higher ability to absorb natural dyes, which increased the cell current and raised the percentage of cell efficiency. Natural red dyes (anthocyanins dye with the metals Cd, Zn, Pb, Hg, and Cu, dye-sensitized DSSCs have cell efficiency of 1.340%, 1.326%, 1,147%, 1,369%, and 1,325%, respectively. Betalain dyes, with the metals Zn, Hg, and Cu, dye-sensitized DSSCs have the cell efficiency of 1.369%, 1.385%, and 1.261%, respectively,) and natural yellow(curcumin dye) with the metals Zn, and Pb, dye-sensitized DSSCs have the cell efficiency of 1.301%, and 1.384%, respectively. This worked to increase the electrical conductivity of the electrodes. Possibly these inorganic substances act as aggregation factors for these pigments on the poles of the cell, which increases the efficiency of the cell.

Authors: Elbarsha Abdelhakim. M. , Farhat Nadeia. M. 
Published: December 2023

Background: Foreign body ingestion, and food impaction, in adults are common emergency department problems. Endoscopic intervention is required for potential therapy to minimize the risk of complications
Aim: To describe the endoscopic findings and interventions for patients with a history of unintentional foreign body ingestion, and food impaction, referred to the adult gastrointestinal endoscopy service.
Methods: Endoscopy reports for all patients referred to adult gastrointestinal service with a history of non-intentional foreign body ingestion, or food impaction were retrieved from the electronic records in the Endoscopy Department at the Benghazi Medical Center, from March 2010 to December 2019, using relevant keywords.
Results: A total of 20 patients (7 males and 13 females), were referred to the adult endoscopy service with a history of either food impaction or non-intentional foreign body ingestion, during the period from March 2010 to December 2019.
Eleven patients had a history of foreign body ingestion, with a foreign body identified and removed in 6 (54.5%) patients.
Nine patients presented with a history of food impaction, while a food bolus was identified and managed in 7 (77.7%) of them.
The most common type of impacted food in the study series was a piece of meat stuck in the esophagus (4 patients). In three patients, the piece was removed and in the fourth, it was pushed into the stomach.
Conclusions:The number of referred cases to our Endoscopy Department is relatively small. In more than half of the patients, foreign body or food bolus or material could be identified, and in all of them, endoscopic management was successful with no reported complications.

Authors: Ali Muna .M. , Albargathi Haleemah. A. , Belkhair Hussain. A. 
Published: December 2023

Background: Septoplasty is one of the commonest procedures done in ENT department in which bleeding necessitate packing. Nasal packing is painful and it may be the fearful step of surgery by the patient, her we will study the need of nasal packing after this procedure.
Aim: The aim is to determine the need for an anterior nasal pack (A.N.P.) after septal surgery
Patients and methods: This study is a prospective comparative study that was carried out in Al -Hawari Center for 26 months. Eighty-eight patients were operated on and divided randomly on whether or not to apply a nasal pack.
Research data were collected from each patient. Forty-four cases were packed with Vaseline gauze or merocele and the remaining 44 cases were not.
Results: A total of 88 subjects were included with 44 in each group. the mean age of septal surgery cases was 28.1 years of age; standard deviation (S D) =7.4. The minimum and maximum ages were 18 and 48 years respectively. For the primary outcome of the study (post-operative bleeding, headache and pain), there were no statistically significant differences between the two groups (P-values 0.15, 0.39 and 0.38 respectively). However, The overall complications in both groups show a p-value of 0.02 which is a statistically significant difference
Conclusion: In this small series study, we noticed no significant benefit of nasal packing. On the other hand, it increases the patients suffering by causing complete nasal obstruction, pain and headache. It increases the length of the hospital stay and so the overall cost. Therefore, nasal packing may be of use only in selected cases where bleeding tendencies are more. In a cleanly-performed surgery that does not cause bleeding, nose packing is not needed.

Authors: Abdeldaim Guma M. K. , Abdraba Ilham O. A. , Qowaider Salema R. M. , Ali Marfoua S. 
Published: December 2023

Background: Hepatitis B virus (HBV) infection is a global public health problem, with about 240 million people affected worldwide. Serologic techniques are typically used to diagnose it. However, the decision as to which patient to treat or not remains challenging due to the poor sensitivity of serologic markers as prognostic or severity markers. Viral load (VL) determination using polymerase chain reaction techniques is a useful tool in decision-making.
Aim: The aim of this study was to determine the pattern of HBV viral load levels in people of different age and sex groups, to predict the risk of hepatocellular carcinoma and liver cirrhosis in HBsAg positive patients in the east of Libya.
Materials and Methods: This is a retrospective and descriptive study. Only one HBV VL test carried out on patients attending the Benghazi university center (from east of Libya) for specialized medical services prior to any HBV targeted therapy were included in the study over a period of 40 months (January 2014 to April 2018) . Hepatitis B DNA VL determinations were analyzed using Microsoft Excel 2010 and Minitab version 17.
Results: A total of 431 patients, of whom 51.3% (210) were males and 48.7% (221) were females, were included in the study. Of the 431 patients, 31.3% (135) were below 30 years old, while 68.7% (296) were 30 years old or above. Around 31.1% (134) had measurable assay levels (20 - 2000 (Taq) IU/mL); 21.8% (94) had below 20 IU/mL; and 13.2% (57) had above 2000 IU/ml approximately 21.1% (91) had no detectable HBV DNA in their samples. 12.8% (55) of the patients had levels greater than 20000 IU/mL. The distribution of HBsAg positivity among the patients shows an increasing trend from the lower age group 0-10 to 21-30 in males and from 31-40 in females, then a decreasing trend from 31-40 to 81-90 age group in males and from 41-50 to 81-90 age group in females. A total of 431 patients were investigated for hepatitis B viral load, of whom 90.2% were HBeAg negative and 9.8% were HBeAg positive.

Authors: EL Daffri Hanan , Mohammed Najat M.H. , Amraje Fatma , Khaled Fyrouz , Ali Alnagy Mohammad 
Published: December 2023

Background: Chlorpyrifos (CPF) is one of the most common pesticides that is extensively applied in agriculture and animal houses. Several experimental studies on rats demonstrated that exposure to CPF elicits a group of deleterious effects including hepatic dysfunction, immunological defect and neurotoxicity. Moreover, there is concern regarding their deleterious effects on human life. This study investigated the influence of chlorpyrifos on the hepatic tissue of adult male rabbits in long-term exposure and evaluated the protective role of vitamin E in ameliorating toxic impacts.
Methods: Twenty adult male rabbits were used in the study. Their average weight was (27.6 ±1.891) Kg. They were divided into four groups, five animals in each. The control group received only distilled water. The CPF-treated group was administrated 33.3mg/Kg of insecticide orally by gastric gavage. The vitamin E group received only Vit E; 150mg/kg body weight. Animals in the combination group were treated with CPF and given Vit E at the same time. The treatment was applied once daily in the morning after a food supplement for 12 weeks. Animals were then anesthetized with chloroform, their livers were removed, placed in formalin, processed and stained with hematoxylin and eosin, and with Masson's trichrome
Results: Histopathological changes showed that CPF caused degenerative changes in hepatocytes in terms of vacuolization of cytoplasm, congestion, dilatation of the sinusoidal lumen, and leukocytic infiltration of liver parenchyma, as well as the presence of signs of fibrosis manifested by trichrome stain indicating the chronic effect of pesticides. In the combination group, the majority of hepatocytes presented with normal structures, and the amount of fibrosis was diminished around the portal area. Additionally, congestion appeared to a milder degree than in the experimental group, suggesting the antioxidant role of vitamin E in reducing toxic effects. Conclusion: The study concluded that CPF could cause hepatocellular damage to the rabbits' tissue which can be alleviated by applying antioxidants such as vitamin E.

Background: Neoplastic and non-neoplastic prostate gland lesions are the main reasons for morbidity and mortality throughout the world. The risk of diseases increases with age. Basically, Prostate biopsy is a test which detects malignant and other benign conditions of the prostate in patients who have urinary symptoms. Other modalities of diagnosis also have been developed, comprising of radiological modalities and prostatic biomarkers. However, biopsy with microscopic examination is the gold standard for the ultimate diagnosis.
Objectives: The present study was done to recognize and determine the different histopathological patterns of prostatic diseases and their clinical presentation correlations.
Patients and methods: Reviewing of 194 patient specimens of prostatic tissues in the department of pathology, faculty of medicine, university of Benghazi from January to December 2009 was conducted. The received specimens were fixed in 10% neutral buffered formalin and routine paraffin processing followed by hematoxyline and eosin staining was done. All the specimens were analysed with following parameters: type of specimen, age of patient, histopathological pattern and final diagnosis. With application of modified Gleason scoring for grading.
Results: 131 TURP, 42 needle biopsies, and 21 prostatectomy specimens were assessed, they were grouped into benign, premalignant, and malignant disorders. Modified Gleason`s Scoring was used to score the prostatic adenocarcinoma. The Mean of all patient's age was 70.7 years. 153 (78.87%) were benign, 7 (3.6%) were premalignant and 34 (17.53%) cases were malignant. Malignant to benign ratio (1: 4.7). Age ranged was 24-100 years. The most frequent disease encountered was BPH, mainly in the sixth decade. Glandular-stromal pattern was more frequently seen (86.8%), followed by glandular predominance (13.2%). Concomitant conditions such as prostatitis, Basal cell hyperplasia, squamous metaplasia, and atypical adenomatous hyperplasia (AAH) (premalignant) were observed. Among the malignant conditions, acinar adenocarcinoma was the commonest disease seen in sixth and seventh decades by (91%), and Gleason`s score 7 was the commonest. One of the cases was metastatic TCC from urinary bladder.
Conclusion: Benign lesions of prostate are more common than malignant lesions, most commonly encountered in age group of 61 to 70 years. There is a major difference in symptoms between malignant and benign conditions. More studies are needed in future to identify environmental and social factors contributing prostate disease.

Published: December 2023

This study is an attempt to describe some aspects relating to the blood cells of one of Libya's wildlife animals, the long-eared hedgehog (Hemiechinus auritus). The investigation focused on the morphology of the blood cells in newborn and adult animals that were obtained from the city of Benghazi. Four one-day-old hedgehoglets and 20 adult hedgehogs were utilised to prepare stained blood smears. Structural features of blood cells of both young and adult animals did not show prominent variations from each other. Neutrophils nuclei had a band and multilobulated appearance. The maximal number of nuclear lobes reached seven in the newborn hedgehogs and eight in the adult and the joining threads between the lobes were mostly very obvious. The Barr body could not be observed in neutrophils of the female animals. Non-lobulated nuclei were encountered in the eosinophils of the adult animals, whereas the nuclear trilobulation could be noticed in the eosinophils of both groups of hedgehogs. Basophils of the newborn hedgehogs showed large irregular nuclei, whereas those of the adults had partially divided indented nuclei. Small, medium and large lymphocytes could be observed in blood films of the newborn and adult animals. However, the majority of the lymphocytes were small in size. Eccentrically located nuclei with kidney-shaped, horseshoe, oval and round appearances were recorded in monocytes of both groups of animals. Platelets of the newborn and adult hedgehogs were non-nucleated and had round to oval shapes. A centrally located dark area surrounded by a less dense area was obvious. The discoid non-nucleated erythrocytes had a biconcave appearance in both groups of hedgehogs.
