Abstract Background: The cystic endometrial hyperplasia-pyometra complex (CEH-P) is one of the most common uteropathies in bitches. In diseases with mild or obscure clinical signs and normal uterine size, a diagnosis based on a clinical assessment might be incorrect. The main aim of the research was to determine the morphological variables accompanying uterine diseases in bitches in microscopic evaluation. Consequently, the obtained results can be used to create a new classification system for uterine pathological changes during the development of the CEH-P, diagnosed by microscopic examination in bitches. Material for the study consisted of the uteri of 120 female dogs, aged 1-16 years, obtained during routine ovariohysterectomies. Macroscopic observation after a longitudinal incision of the uterine horns, allowed a preliminary classification of the uteri into research groups: control group (physiological uteri), and groups GI-III uteri collected form bitches with varying degrees of endometrial pathology. These preliminary classifications were then verified by histological analysis (H&E stain).Results: The obtained results made it possible to determine and describe the prevalence (%) of pathological changes characteristic of the analyzed uterine diseases in the examined bitches. Histopathological analyses that were conducted have confirmed preliminary macroscopic evaluation for the control group, group GII (CEH), and group GIII (pyometra). In the uteri of the GI group, a severe congestion of endometrium has been observed – this is typical of inflammation – which was not confirmed during histopathological examinations. However, these examinations revealed acute endometrial haemorrhage of varying severity.Conclusions: Early reproduction disorders in bitches are, in general, not confirmed by clinical signs in the examined animals. The results show that during classification of typical morphological changes in endometrium over the development of the CEH-P complex in bitches microscopic examinations are required. The obtained results indicate a frequent lack of consistency in the macroscopic assessment and histological analysis of the endometrium, observed in the analyzed uterine diseases, which in most cases is not followed by clinical symptoms. The presented classification of uterine diseases may be useful as a diagnostic tool in reproductive disorders in bitches and in examination in the field of basic research.

Abstract Background: The aim of the analysis was to designate the morphological symptoms that appear during the Cystic Endometrial Hyperplasia - Pyometra complex (CEH-P), diagnosed by microscopic examination. The investigation were conducted on the uteri of 120 bitches in age between 1 – 16. The microscopic examinations were based on histological stainings. The aim of examinations was to find the differences in morphology of endometrium in the specimens of the uteri wall (H&E stain). All of the uteri were divided into three pathological groups (GI – GIII), created on the basis of macroscopic examinations of analyzed diseases. Uteri without macroscopic pathological changes were classified as a control group (C).Results: Histopathological analysis that were conducted have confirmed preliminary macroscopic evaluation for control group with unchanged uteri, group GII with cystic endometrial hyperplasia of uteri (CEH), and group GIII with uteri with pyometra. The confirmation of compatibility of both macroscopic and microscopic evaluation of the uteri were observed in groups GII and GIII. In the uteri of the group GI a severe congestion of endometrium have been observed – it is typical for the inflammation – which was not confirmed during histopathological examinations. Those examinations revealed only endometrial haemorrhage.Conclusions: The results are showing that during classification of research material microscopic examinations are required. The diagnose based on the macroscopic changes in typical for CEH-P symptoms might be incorrect, if it is not supported by detailed research. More than that, in all uteri with the closed pyometra the CEH was also observed. It suggest that pyometra may occur as a consequence of cystic endometrial hyperplasia and bacterial infections ended with inflammation. The results obtained can be used to create a basis for pathologic classification of endometrial hyperplasia and indicate typical morphological changes in endometrium during development of CEH-P complex in bitches.

Retinoid Treatment

The study aimed to evaluate the effect of retinoid treatment on the morphological changes in the nail apparatus in patients with nail psoriasis. Material and methods: 41 patients aged 32 to 64 with nail psoriasis, without clinical signs of psoriatic arthritis, started on acitretin 0.6 to 0.8 mg kg b.w./d, for six months and 28 people in the control group were included in the study. Both groups had ultrasound examination of fingernails and digital extensor tendon in the distal interphalangeal joints. In psoriatic patients, US examination was conducted before starting the treatment and after six months. A total of 685 nails were examined. Results: After six months of treatment, there was a reduction in the thickness of the nail bed and nail matrix (p = 0.046 and p = 0.031, respectively). The thickness of the nail plates decreased, although it was statistically insignificant (p = 0.059) and it was higher than in the control group (p = 0.034). The reduced severity of clinical nail changes after six months of retinoid treatment did not correlate with the reduction in extensor tendon thickness in any group of patients. Conclusions: In patients with nail psoriasis, acitretin treatment resulted in a rapid decrease in the thickness of the nail bed and matrix, but it did not affect the thickness of the nail plate after six months. There was no effect of acitretin on the digital extensor tendon thickness or the increased blood supply to the tendon area. The results of the study may indicate the usefulness of ultrasound nail examinations in patients with nail psoriasis not only to assess the advancement of morphological changes and response to treatment, but also to choose the potential treatment.

Abstract Introduction: The objective of this study was to analyze the morphological structure of the heart and aorta of rats treated with the synthetic glucocorticoid dexamethasone. Material and Methods: Male Wistar rats were divided into two groups: 08 control rats undergoing treatment with a 0.9% saline solution for 10 days and 08 rats treated for 10 days with dexamethasone (2mg/kg animal weight). Results: Histological analysis detected a mild cardiac hypertrophy and 15% reduction of collagen located in the aorta of animals treated with glucocorticoid when compared to the control group. Conclusion: We conclude that treatment with dexamethasone for a period of 10 consecutive days is able to promote morphological changes in the structure of the heart chamber and, impair morphological structure of aorta.

The aim of this study was to identify the effect of zinc-enriched diet fed to goats and their kids on the number of Coccidia oocysts shed by kids, on clinical signs of coccidiosis, weight gains, and kids’ blood plasma concentration of zinc. A total of 22 goat kids were divided into 4 groups of 5 or 6 animals. Goats and kids from the control group did not receive any additional zinc, the second group was supplemented with inorganic zinc (zinc oxide), the third group was given zinc lactate, and the fourth group received chelated zinc. Samples of kids’ faeces were taken weekly from 3 to 9 weeks of their age (a total of 7 samples were taken). Samples of faeces were examined by a quantitative method to detect the number of oocysts. Kids were weighed weekly and their blood was taken in order to determine zinc concentrations in blood plasma. Animals from the group supplemented with zinc chelate and zinc lactate shed a significantly (p ≤ 0.05) lower number of oocysts (13.4% and 11.9%, respectively) compared to the number of oocyst shed by control and zinc oxide supplemented groups (25% and 49.7%, respectively). Shedding of oocysts was not accompanied by clinical symptoms of coccidiosis in any of the groups. Kids supplemented with zinc chelate showed significantly highest weight gains and blood plasma concentration of zinc (p ≤ 0.05) as compared to control and inorganic zinc supplemented groups. Organic zinc is to be recommended to be used as a prophylaxis against coccidiosis in goat kids.

Background: Previous studies do not agree with each other on the association between electrodiagnostic findings and clinical symptoms of Carpal tunnel syndrome (CTS). In most of these studies, many variables such as age, sex, obesity and hypothyroidism have not been taken into account. Material & methods: About 62 patients with hypothyroidism and 62 patients without hypothyroidism with sign and symptoms of CTS were included in this study. Electrodiagnostic tests were done for all patients. And relationship of the severity of CTS signs and symptoms with electrodiagnostic parameters was examined statistically in each group. Results: This study showed that distal motor latency in control group (without hypothyroidism) is significantly more prolonged than hypothyroid patients. Also there was significant correlation between clinical symptoms and electrodiagnostic findings in control group, but there was not such correlation in hypothyroid patients. In 62% of hypothyroid patients with clinical signs and symptoms of CTS, electrodiagnostic findings were normal and only in 38% of cases, electrodiagnostic findings were suggestive of CTS. Conclusion: Relationship of the severity of CTS signs and symptoms with electrodiagnostic parameters is very weak in hypothyroid patients. Many hypothyroid patients with clinical signs and symptoms of CTS have normal electrodiagnostic findings; so we need more studies for revising the para-clinic criteria of labeling patients having CTS in hypothyroid patients.

Objective: To analyze the immunoprotection of pigs by heterologous P. acnes vaccination against A. pleuropneumoniae infection, by vaccine and infection in pig. Methods: 12 five-week-old healthy pigs were randomly divided into 2 groups, of which 1 group (n=6) was vaccinated twice with living P. acnes and the other group served as a non-vaccinated control (n=6). Both groups were experimentally infected with A. pleuropneumoniae (serotype 1, 5*107 CFU, CCVC 259) then the clinical symptoms and pathological changes were monitored. Results: Compared to the control group, the vaccination group showed significantly reduced clinical symptoms and pathological changes. The P. acnes-vaccinated group showed a significant increase in the levels of specific serum antibody titer against A. pleuropneumoniae soluble antigen and serum IL-2 and IL-4 concentration. Conclusion: Immunization with heterologous P. acnes enabled an effective humoral immune response against A. pleuropneumoniae infection in pigs.

Purpose: To investigate the effect of crude polysaccharide isolated from pao-tian-xiong on chronic renal failure in mice, and its monosaccharide composition. Methods: Male Kunming mice were orally treated with adenine (211.5 mg/kg/day) for 7 days, followed by either crude polysaccharides (125, 250 or 500 mg/kg), or positive drug solution (jinguishenqi pill, 2000 mg/kg) for another 7 days (each group had 15 mice). Mice in normal and negative control groups were given saline. Mental and physical states, blood urine nitrogen (BUN) and serum creatinine (SCr), kidney morphological changes and organ indices were determined. Histopathological examination of spleen and kidney tissues was also performed. The monosaccharide composition of crude polysaccharide was determined by high-performance liquid chromatography (HPLC) and gas chromatography and mass spectrometry (GC-MS). Results: Compared with negative control group, serum BUN (6.71 mmol/L vs. 8.61 mmol/L) and Cr (107.74 vs. 113.39 μmol/L) were significantly decreased by the crude polysaccharide isolate (p < 0.05), whereas epididymis index (0.2556 vs. 0.2135 %) and seminal vesicle index (0.5547 vs. 0.3945 %) were increased (p < 0.05). Histopathological examination showed that injuries to kidney, spleen, testis and epididymis decreased significantly. The crude polysaccharides contained mainly glucose, rhamnose, arabinose, galactose, mannose, galacturonic acid, glucuronic acid and xylose, and their contents ranged from 0.7 to 65 %. Conclusion: These results suggest that the crude polysaccharides of Pao-tian-xiong ameliorates CRF symptoms in mice, thereby providing experimental evidence in support of its use as an anti-CRF drug.

Objective: We hypothesized that omega-3 fatty acids would be an appropriate adjunct therapy for alleviating the inflammatory response and clinical manifestation in hospitalized patients with covid-19 disease. Methods: This was a single-blind randomized controlled trial in Amir-Alam hospital in Tehran. Thirty adult men and women diagnosed with covid-19 were allocated to either control group (receiving Hydroxychloroquine) or intervention group (receiving Hydroxychloroquine plus 2 grams of DHA+EPA) for 2 weeks. Primary outcome of the intervention including CRP, ESR as well as clinical symptoms including body pain, fatigue, appetite and olfactory and secondary outcomes including liver enzymes were determined at the baseline and after omega-3 supplementation. Clinical signs were measured using self-reported questionnaires. There were commercial kits for determination of CRP and liver enzymes concentrations in the serum of patients. For determination of ESR automated hematology analyzer was applied. Results: In comparison to control group, patients receiving omega-3 indicated favorable changes in all clinical symptoms except for olfactory ((p<0.001 for body pain and fatigue, p= 0.03 for appetite and p=0.21 for olfactory). Reducing effects of omega-3 supplementation compared to control group were also observed in the levels of ESR and CRP after treatment (p<0.001 for CRP and p=0.02 for ESR). However, no between group differences in the liver enzymes serum concentrations were observed after supplementation (p>0.05). Conclusion: Current observations are very promising and indicate that supplementation with moderate dosages of omega-3 fatty acids may be beneficial in the management of inflammation-mediated clinical symptoms in covid-19 patients. Key words: Covid-19, omega-3, inflammation, clinical symptoms
