The aim of this study was to detect the microscopic and macroscopic lesions in uterine tubes and uterus in Sluaimani abattoir, Kurdistan region/Iraq. The total samples collected were 340 genitalia of does of pregnant and non-pregnant. 37.05% (126/340) of the samples were pregnant and 37.35% (127/340) of the samples were observed without gross lesions and 2.23% (10/340) were noticed with uterine tube gross abnormalities and the remaining 34 (12.941%) samples were recorded as anatomical lesions and pathological lesions of uterus. The a numbers of uterine tubes abnormalities were 11 out of 340 specimens (3.235%), and the most common lesions were; salpingitis 6 cases (7.64%); 1 case from each of hydrosalpinx and Pyosalpinx, respectively (0.294%). Microscopically, the lesions of salpingitis were sloughing off the part of the epithelium and infiltration of inflammatory cells. Three specimens of cyst on uterine tubes (0.882%). The numbers of uterine lesions were 44 specimens which shared 12.941% of abnormalities out of the 340 collected specimens. The most common diseased genital cases were; endometritis and metritis which 21 cases (6.176%), which were histopathologically characterized by a significant increase in the endometrial thickness due to diffuse infiltration of inflammatory cells mainly lymphocytes, the proliferation of fibroblasts with deposition of extracellular matrix. Five pyometra (1.470%), which was histolopatholgically characterized by definite increase in the uterine wall thickness, especially in the endometrium due to infiltration of light pinkish fibrinous inflammatory exudates with mild inflammatory cell proliferation. Three Hydrometra specimens (0.882%), and five endometrial cystic hyperplasia (1.470%). The microscopic lesions for them include massive cystic dilatation of the uterine gland that contains pinkish granular secretion, infiltration of light pinkish edematous fluid in the endometrial stroma associated with inflammatory cells. Two specimens of uterine wall with cysticercus tenuicolis (0.588%), and one uterine melanoma (0.294%), The histopathological features for the uterine melanoma include; deposition of the dark black melanin pigment within the phagocytic cells. Uterine leiomyosarcoma was one specimens (0.294%), which histologically, appear as pleomorphic cells variable in shape and size with different nuclear size randomly oriented in different directions, some of these cells were hyperchromatic with an abnormal mitotic figure. One case of cyst on the uterine wall was found (0.294%), and five cervicitis (1.470%). Finally, it could be concluded that uterine tubes, and uterus abnormalities constitute a percentage (3.235%, and 12.941%), respectively. In this study, uterine melanoma, and uterine leiomyosarcoma were firstly recorded in this study in Iraq and Kurdistan region.

Lung Fluid

The proteinase-antiproteinase theory for the pathogenesis of emphysema proposes that the connective tissue destruction associated with emphysema arises from excessive proteinase activity in the lower respiratory tract. For this reason, the relative activities of neutrophil elastase and alpha 1-proteinase inhibitor (alpha 1-PI) are considered important. Most emphysema is observed in smokers; therefore, alpha 1-PI has been studied as a target for smoke-induced damage. Damage to alpha 1-PI in lung fluid could occur by several mechanisms involving species delivered to the lung by cigarette smoke and/or stimulated inflammatory cells. Oxidative damage to alpha 1-PI has received particular attention, since both cigarette smoke and inflammatory cells are rich sources of oxidants. In this article we review almost two decades of research on mechanistic studies of damage to alpha 1-PI by cigarette smoke and phagocytic cells in vitro, studies emphasizing the importance of elastinolytic activity in the pathogenesis of emphysema in vivo and studies of human lung lavage fluid to detect defects in alpha 1-PI at the molecular and functional levels.

Eosinophilic enteritis, an increasing recognized condition, is rare and often presents with non-specific symptoms. We report a case of a 46-year old female who presented with acute onset abdominal pain and nausea associated with ascites, small bowel thickening and peripheral eosinophilia. Diagnosis was confirmed by biopsies taken at esophagogastroduodenoscopy demonstrating diffuse infiltration by inflammatory cells, mainly eosinophils. Appropriate therapy was instituted. The patient recovered well and was symptom-free at 1-month follow up. In this report, we discuss the clinical presentation and the diagnostic criteria of the eosinophilic enteritis, and examine the pathophysiological theories and therapeutic strategies. The relevant literature on eosinophilic enteritis is summarized.

This experiment was conducted to determine the pathology of pullorum disease of chickens and molecular identification of its pathogen. A total of 108 samples, including swabs from different organs were collected from different commercial layer farms of Gazipur district. The histopathological samples were collected in 10% formalin and the swabs were collected in tetrathionate broth. Samples were subjected to isolation and identification of the causal agent followed by gross and histopathological study of the affected visceral organs. Fifty eight out of 108 cloacal swabs (53.7%) were Salmonella positive. The percentage of Salmonella positive in liver swabs, spleen swabs, lung swabs and intestinal swabs from dead birds were 55.88%, 32.35%, 35.29% and 47.05%, respectively. On average, 52.94% livers of Salmonella affected birds were enlarged, congested and hemorrhagic and necrotic foci was present in 32.35% liver. Unabsorbed and coagulated yolk was found in 70.58% cases. From these 38.24% spleens were swollen and congested and 44.12 % kidneys were enlarged. At histopathology, 52.94% livers showed congestion, focal necrosis with multifocal infiltration of histiocytes in liver parenchyma. Focal necrosis and inflammatory cells were found in 70.58% spleen. Infiltration of heterophils in intestinal mucosa was found in 47.05% cases. 20.58% (7 out of 34) samples were PCR positive for Salmonella Pullorum organism. Ann. Bangladesh Agric.

Degree Of Degradation

Isotopically labelled sperm was used to investigate the fate of the uterine sperm residue not used in the process of fertilization of the mouse. Portion of the sperm present in the uterus exhibiting a copulation plug was removed and replaced by intrauterine injection of sperm labelled either specifically by tritiated thymidine or non-specifically by exposure to a tritium source. The latter label was found more suitable for tracer use although the results with both methods were qualitatively similar. Seventeen hours after injection label was present in sperm in the lumen, in debris associated with polymorphonuclear granulocytes and monocytes in the lumen, in the epithelial and subepithelial coats of the mucosa and in phagocytic cells of the lower abdominal lymph nodes and spleen. The density of labelling was greatest in the sperm itself then fell away sharply and uniformly in the other sites. Label was present at this time in sperm spilled into the peritoneal cavity via the needle track. Associated with this spillage, label was seen in peritoneal polymorpho- nuclear granulocytes and macrophages, in macrophages of the uterine wall, and in phagocytic cells of the lymph nodes and spleen. The density of labelling was greatest in the sperm itself but the density decline in these other sites was less than in these same sites resulting from sperm retained wholly in the uterine lumen. Labelled sperm was present in all experiments in the vaginal lumen. The relation between the density of labelling and the degree of degradation of the sperm products is discussed and it is reasoned that the female cells are exposed to less degraded sperm products as a result of entry via the peritoneal cavity than entry via the uterine mucosa. This route may be thereby more effective as an antigenic stimulant.

Abstract Background The genus Entamoeba has many species that are invasive or non-invasive (E. histolytica, E. dispar, and E. moshkovskii).The invasive E. histolytica is the main pathogenic amoeba in human. Amoebiasis involves several stages starting with the adherence of the parasite to the intestinal epithelium, followed by degradation, tissue invasion, and distribution to other organs. Results The current study investigates the pathological changes of Entamoeba spp. infection in both rectum and cecum of experimental rats. The results showed the histological changes at the 7th, 14th, and 28th day post-infection for the three species. E. histolytica and E. moshkovskii infection showed less pathological changes compared to E. histolytica. These changes include the attachment of the trophozoites to the mucosal layer, significant surface epithelial changes such as dissociation and degeneration in the mucosal layer, and ulceration of the apical surface. Inflammatory cells infiltrate the varied regions, extending into the deep mucosa causing mild architectural alterations. These are features of amoebiasis. Conclusion The pathological changes reported in E. dispar and E. moshkovskii were less severe than E. histolytica.

ABSTRACT Objectives To study the diagnostic accuracy of folliculometry and endometrial echo complex as an evidence of ovulation in infertility. Materials and methods This clinical study was conducted on 100 infertile women. The women were subjected to follicular monitoring by transvaginal sonography (TVS) from cycle day 8 or 10 of menstruation with 7.5 MHz vaginal probe of Siemens ultrasound machine. Evidence of follicular growth, ovulation, and morphology of endometrial echo complex with its thickness was noted. Endometrial biopsy was performed premenstrually as a day care procedure after excluding pregnancy. Results Out of 100 women, 81 cases were with evidence of ovulation on TVS and 68 were confirmed on histopathology. All the studied patients were also evaluated for endometrial thickness on the day of ovulation, echo complex of endometrium suggestive of ovulation was seen in 64 cases, out of these 59 cases were confirmed on histopathology. On histopathological study of 100 cases, we found 69 cases with secretory endometrium, 18 with proliferative endometrium, 10 patients with endometritis, one each with luteal phase defect, irregular shedding of endometrium, and hormonal imbalance. Conclusion We found folliculometry predicted ovulation 86% accurately with a specificity of 58.60% and sensitivity of 98.55%. Similarly, appearance of endometrium predicted ovulation 85% accurately with a specificity of 83.80% and sensitivity of 85.50%. Thus, TVS has undeniable advantages in terms of cost, time, acceptability, risk, convenience, and could easily diagnose signs of ovulation in cases of infertility. The TVS has quintessential role as the first diagnostic modality in patients presenting with infertility. How to cite this article Katiyar S, Arya SB, Goel JK, Sinha M.

Abstract Background: To date, very few studies on clinical-histopathological correlations of cutaneous disorders associated with COVID-19 have been conducted. Case presentation: The Case 1 was a 90-year-old man, who tested positive for SARS-CoV-2 from a nasopharyngeal swab. Two days later, he was hospitalized and after eleven days transferred to Intensive Care Unit. A chest CT showed bilateral ground-glass opacities. Just that day, an erythematous maculo-papular rash appeared on trunk, shoulders and neck, becoming purpuric after few days. Histological evaluations revealed a chronic superficial dermatitis with purpuric aspects. The superficial and papillary dermis appeared edematous, with a perivascular lympho-granulocytic infiltrate and erythrocytic extravasation. At intraepithelial level, spongiosis and a granulocyte infiltrate were detected. Arterioles, capillaries and post-capillary venules showed endothelial swelling and appeared ectatic. The patient was treated with hydroxychloroquine, azithromycin, lopinavir-ritonavir and tocilizumab. Regrettably, due to severe lung impairment, he died.The Case 2 was a 85-year-old man, admitted to Intensive Care Unit, where he was intubated. He had tested positive for SARS-CoV-2 from a nasopharyngeal swab two days before. A chest RX showed bilateral atypical pneumonia. After seven days, a cutaneous reddening involving trunk, upper limbs, neck and face developed, configuring a sub-erythroderma. Histological evaluations displayed edema in the papillary and superficial reticular dermis, and a perivascular lymphocytic infiltrate in the superficial dermis. The patient was treated with hydroxychloroquine, azithromycin, lopinavir-ritonavir and tocilizumab. Sub-erythroderma as well as respiratory symptoms gradually improved until healing. Conclusions: The endothelial swelling detected in the Case 1 could be a morphological expression of SARS-CoV-2-induced endothelial dysfunction. We hypothesize that cutaneous damage could be initiated by endothelial dysfunction, caused by SARS-CoV-2 infection of endothelial cells or induced by immune system activation. The disruption of endothelial integrity could enhance microvascular permeability, extravasation of inflammatory cells and cytokines, with cutaneous injury. The Case 2 developed a sub-erythroderma associated with COVID-19, and a non-specific chronic dermatitis was detected at histological level. We speculate that a purpuric rash could represent the cutaneous sign of a more severe coagulopathy, as highlighted histologically by vascular abnormalities, while a sub-erythroderma could be expression of viral hematogenous spreading, inducing a non-specific chronic dermatitis.

Background: Radiation-induced pneumonitis and fibrosis are the most common side effects of chest radiotherapy. They result from massive and chronic production of Reactive Oxygen Species (ROS), inhibition of antioxidant enzymes as well as the release of several inflammatory mediators. In this study, we aimed to detect the radioprotective effects of metformin (as inhibitor of mitochondrial ROS), resveratrol (as stimulator of antioxidant defense enzymes) and alpha-lipoic acid (as direct antioxidant) for alleviating radiation-induced pneumonitis and fibrosis. Methods: 80 Male Mice were randomly allotted to eight groups which include G1: control; G2: resveratrol; G3: alpha-lipoic acid; G4: metformin; G5: radiation; G6: radiation plus resveratrol; G7: radiation plus alpha-lipoic acid; G8: radiation plus metformin. Drugs’ doses were as follows: 100 mg/kg metformin, 200 mg/kg resveratrol and 200 mg/kg alpha-lipoic acid. Irradiation with a single radiation dose of 18 Gy was performed using a cobalt-60 (60Co) gamma-ray source. After 80 days, all mice were sacrificed and their lung tissues evaluated for morphological changes using histopathological markers. Results: Irradiation led to acute pneumonitis including infiltration of inflammatory cells and damages to alveolar and vascular, as well as mild fibrosis. Metformin, alpha-lipoic acid and resveratrol were able to reduce pneumonitis and overcome radiation-induced fibrosis. Conclusion: All agents could protect against radiation-induced lung injury moderately. It is possible that administering higher doses of these drugs over a long period of time could give better radioprotection of the lung.
