On the basis of morphological, pathologoanatomic, histological and morphometric researches, the morphological structure of clinically healthy dog's pancreas and at chronic pancreatitis were determined in the article. Having used morphometric researches were found that the absolute mass of dog's pancreas at chronic pancreatitis towards clinically healthy dogs, increased for 1,28 times from 29.3 ± 3.0 g in healthy animals to 38.33 ± 7.02 g in ill ones. The relative weight of organ increased in 1.19 times and was 0.19 ± 0.04 % in comparison with the control 0.16 ± 0.03%.Owing to the histological researches, was found the structure breach of pancreatocites. In acinar cells, cytoplasm zoning did not occur, pancreatocites poorly perceived coloration and contained inclusions in the form of drops. The kariolisis cores was present. In Pancreatic islets focal hemorrhage were observed as well as the destruction of endocrine cells. Inter particle connective tissue layer were thickened and in organ's glandular tissue were presented bands that penetrate and branch in depth of a particle. It was determined on the basis of morphometric researches that the value of pancreacites and their nuclei in ill animals truly (р < 0,05) increases and was namely 455.51 ± 33.24 та 54.90 ± 7.24 mcm3 (in clinically healthy ones namely – 356.06 ± 11.37 та 33.69 ± 1.62 mcm3). The nucleus cytoplasm relation of pancreacites of pancreas in dogs at chronic pancreatitis towards the relation to clinically healthy dogs, increased for 1.44 times and was 0.177 ± 0.04. In dogs of the control group such indicator was 0.123 ± 0.001.

Abstract Context Chronic pancreatitis (CP) is characterized by inflammation, fibrosis, and a loss of pancreatic acinar cells, which can result in exocrine and eventually endocrine deficiency. Pancreatitis has been reported to induce formation of new endocrine cells (neogenesis) in mice. Our recent data have implicated chromogranin A–positive hormone-negative (CPHN) cells as potential evidence of neogenesis in humans. Objective We sought to establish if CPHN cells were more abundant in CP in humans. Design, Setting, and Participants We investigated the frequency and distribution of CPHN cells and the expression of the chemokine C-X-C motif ligand 10 (CXCL10) and its receptor chemokine C-X-C motif receptor 3 in pancreas of nondiabetic subjects with CP. Results CPHN cell frequency in islets was increased sevenfold in CP [2.1% ± 0.67% vs 0.35% ± 0.09% CPHN cells in islets, CP vs nonpancreatitis (NP), P &lt; 0.01], as were the CPHN cells found as scattered cells in the exocrine areas (17.4 ± 2.9 vs 4.2 ± 0.6, CP vs NP, P &lt; 0.001). Polyhormonal endocrine cells were also increased in CP (2.7 ± 1.2 vs 0.1 ± 0.04, CP vs NP, % of polyhormonal cells of total endocrine cells, P &lt; 0.01), as was expression of CXCL10 in α and β cells. Conclusion There is increased islet endogenous expression of the inflammation marker CXCL10 in islets in the setting of nondiabetic CP and an increase in polyhormonal (insulin-glucagon expressing) cells. The increase in CPHN cells in CP, often in a lobular distribution, may indicate foci of attempted endocrine cell regeneration.

AbstractThe objective of this study was to investigate the plasma concentrations of insulin-like growth factor-2 (IGF-2) as well as its expression in the uterus and ovary of healthy dogs and those with cystic endometrial hyperplasia (CEH)–pyometra complex. Group 1 (n = 10) included bitches with open cervix pyometra, while Group 2 (n = 7) consisted of clinically healthy bitches in dioestrus. The number of IGF-2 immunopositive interstitial cells was significantly higher in Group 1, whereas in Group 2 there were only two cases in which a few cells were IGF-2 immunopositive. IGF-2 immunopositivity was observed in the endometrial glandular epithelium in both groups. Additionally, interstitial fibroblasts and macrophages in the endometrium were also positive in Group 1. The concentration of plasma IGF-2 was higher in Group 1 than in Group 2 (P < 0.05). The concentration was positively correlated with IGF-2 expression in the endometrial glands (r = 0.926; P < 0.001) in Group 1. However, a negative correlation was present between plasma IGF-2 concentration and IGF-2 expression in the interstitial endocrine cells of the ovary in Group 1 (r = −0.652; P < 0.05). The results suggest that IGF-2 plays an important role during the inflammatory process occurring in bitches with CEH–pyometra complex as well as in the endometrium of healthy bitches in dioestrus.

Pharmacological Potential

The purpose of the study is to improve rehabilitation treatment of patients with chronic pancreatitis (CP) at inpatient stage by strengthening pharmacological potential of drug therapy due to inclusion of therapeutic physical factors (TPF) in therapeutic programs. Materials and methods. 159 patients with acute CP were observed. By simple randomization, 4 groups were formed: the control group (MG, 39 people) received standard drug therapy; 1st comparison group (GC1; 38 people) additionally received TPF; GC2 (40 people) in addition to treatment in GC1 had drinking mineral water «Slavyanovskaya»; in main group (42 people) in addition to the treatment in GC2 got preformed peloidotherapy on the cervical-collar zone. All the patients underwent the evaluation of clinical score and quality of life before and after medical rehabilitation. Results. In MG, clinical symptomatology leveling was by 78,2% (p<0,01), in GC1 — by 71,5% (p<0,01), GC2 — by 62,3% (p<0,01), CG — by 57,2% (p<0,01) on average immediately after the treatment, which was in a clear correlation with indicators of quality of life. In the long term (in 6 and 12 months), the advantage of combination therapy was noted with the same validity, the preservation of the achieved positive result was mostly noted in the MG: after 6 months the improvement in physical health compared to the initial values was noted by 34,4% (p<0,01), after 12 months — by 24,0% (p<0,05); mental — by 32,3% (p<0,01) and 22,5% (p<0,05), respectively. In both comparison groups, positive dynamics was 10–12% lower, and in the control group, after 6 months, there was only a tendency to improve quality of life indicators. Conclusion. The inclusion of TPF in the programs of the inpatient stage of medical rehabilitation of patients with chronic pancreatitis by strengthening the pharmacological potential of drug therapy contributes to the leveling of clinical manifestations (abdominal pain, dyspepsia and diarrhea), the result of which is an improvement in the quality of life of this category of patients.

Replacement of the exocrine parenchyma by fibrous tissue is a main characteristic of chronic pancreatitis. Understanding the mechanisms of pancreatic fibrogenesis is critical for the development of preventive and therapeutic interventions. Cyclooxygenase-2 (COX-2), a rate-limiting enzyme for prostaglandin synthesis, is expressed in patients with chronic pancreatitis. However, it is unknown whether COX-2 can cause chronic pancreatitis. To investigate the roles of pancreatic acinar COX-2 in fibrogenesis and the development of chronic pancreatitis, COX-2 was ectopically expressed specifically in pancreatic acinar cells in transgenic mice. Histopathological changes and expression levels of several profibrogenic factors related to chronic pancreatitis were evaluated. COX-2 was expressed in the pancreas of the transgenic mice, as detected by Western blot analysis. Immunohistochemical staining showed COX-2 was specifically expressed in pancreatic acinar cells. COX-2 expression led to progressive changes in the pancreas, including pancreas megaly, persistent inflammation, collagen deposition, and acinar-to-ductal metaplasia. Quantitative RT-PCR and immunostaining showed that profibrogenic factors were upregulated and pancreatic stellate cells were activated in the COX-2 transgenic mice. Expression of COX-2 in pancreatic acinar cells is sufficient to induce chronic pancreatitis. Targeting this pathway may be valuable in the prevention of chronic pancreatitis. NEW & NOTEWORTHY COX-2 expression is observed in pancreatic tissues of human chronic pancreatitis. In this study, we showed that COX-2 expression caused the development of chronic pancreatitis in transgenic mice, supporting the idea that COX-2 inhibition may be an effective preventive and therapeutic strategy.

Detection Of Biomarkers

The prevalence of comorbidities has been growing for the last decades. Therefore, the detection of biomarkers for diagnostic and prognostic purposes is of great practical importance. The aim of this study was to assess the biomarkers of osteo-defficiency in the course of secondary osteoporosis in patients with comorbid chronic pancreatitis and arterial hypertension. We examined 110 patients with chronic pancreatitis: 70 of them had comorbid hypertension, and 40 patients were found as having no comorbidities. The age of patients ranged from 33.2 ± 2.1 (main group) and 32.9 ± 3.1 years (comparison group); women predominated (72.9% and 70%, respectively). The control group includes 78 healthy individuals of the same age and sex. Diagnostic investigation included studying clinical and anamnestic characteristics of patients (duration of the disease, manifestations of the course, frequency of recrudescence, fractures) and biochemical parameters of bone metabolism: osteocalcin, total bone phosphatase and tartrate-resistant acid phosphatase and the establishment of correlations between these parameters and incidence of complications. It was found that in the isolated course of chronic pancreatitis there is a high (R = 0.60) statistically significant (p <0.01) correlation between the levels of osteocalcin and pancreatic elastase-1. A negative statistically significant (p <0.01) mean correlation (R = -0.49) was found between the content of tartrate-resistant acid phosphatase and age of the patients having comorbidity of chronic pancreatitis and hypertension, as well as there is a moderate correlation between the content of tartrate-resistant acid phosphatase and the duration of hypertension, which is statistically significant (R = 0.36, p <0.01). The levels of total bone phosphatase and tartrate-resistant acid phosphatase in the main group exceeded the reference values in 2.5 and 1.9 times respectively (CMU; U = 866.0; p <0.01), while in the comparison group were 2 times (total bone phosphatase) and 1.3 times higher (tartrate-resistant acid phosphatase) times, respectively (CMU; U = 821.0; p <0.01) that enables to diagnose the development of osteopenic conditions. That is, the combined course of chronic pancreatitis and hypertension should be considered as unfavourable tandem in the development of secondary osteoporosis and requires early osteoporotic screening.

Aim. To determine clinical features and some mechanisms of osteosarcopenia development in patients with chronic pancreatitis (CP). Materials and methods. A casecontrol study was conducted on the basis of the Saratov State Clinical Hospital 5 in 20152018 of patients with CP. In a study of 161 patients with CP included, the control group 30 healthy individuals. Patients were divided into groups according to the etiology of CP: 79 with toxic-metabolic CP, 82 with biliary CP. To determine the risks of low-energy fractures, 154 patients were tested with the Fracture risk assessment tool (FRAX). Along with the standard examination, 30 patients with CP dual-energy X-ray absorptiometry was performed. To assess the state of skeletal muscles, body mass index was determined, hand-held dynamometry was performed, and a set of Short Physical Performance Battery (SPPB) tests was used. Along with the assessment of traditional risk factors for osteosarcopenia gender, age, state of reproductive function in women, body mass index, functional state of the pancreas (pancreas) the quantitative content of interleukins (IL)-2, 6, 8 in in colonic biopsies was analyzed by enzyme-linked immunosorbent assay (ELISA). Results. Bone disorders, according to densitometry, was detected in 70.0% of patients with CP, in 13.3% of the control group. Presarcopenia was detected in 62 (38.5%) patients with CP, sarcopenia in 34 (21.1%), in the control group presarcopenia and sarcopenia were not detected. Sarcopenia was statistically significantly more common in toxic-metabolic CP than in biliary CP (2=11.6; p0.001). Correlations of the lumbar spine T-score and IL-6 (r=-0.29; p=0.03), IL-8 (r=-0.29; p=0.04) were revealed. Correlations between sarcopenia and the concentration of cytokines in the in the colon mucosa in CP were determined (IL-2: r=0.44; p0.001; IL-6: r=0.48; p0.001; IL-8: r=0.42; p0.001). Conclusion. The development of osteopenia and sarcopenia syndromes in CP is interrelated and associated with both traditional risk factors and an increased concentration of cytokines in the in the colon mucosa.

The study was conducted on genitalia collected from 100 dairy cows/heifers from the Meat Technology Unit, Mannuthy. The animals brought for slaughter at Meat Technology Unit, Mannuthy were from herds of five different farms (University and Government Undertaking farms) in Kerala state. This included six animals culled on account of factors other than infertility with normal reproductive system (control group) and the remaining animals with a known history of infertility. In total, seven animals showed kinked cervix condition. Cervix was evaluated morphometrically and histologically. Grossly, the cervix was hard, kinked and S-shaped, with a mean length of 9.64 ± 1.19 cm. Average number of annular rings in the cervical canal was 4.14 ± 0.26 with an average diameter of 1.74 ± 0.18 cm. At the external os, diameter of the cervix was less, while at the uterine end, diameter was more. The opening of each cervical ring showed a misalignment instead of a straight line. Histologically, the cervix was lined by simple columnar epithelium with signs of degeneration and desquamation. However, the submucosal layer was extensively infiltrated by collagen fibres. In uterus, there was a significant difference in the number of endometrial glands and height of the glandular epithelial cells which was less when compared to the control group. Muscular layer outer to connective tissue layer was thin and uneven. Alterations of the glandular structures negatively influence the viability of spermatozoa due to the lack of secretory products. This fibrous, collagen rich kinked cervix limits the smooth deposition of the semen into the uterus during artificial insemination and the insufficiently dilated cervix affects its contractibility leading to dystocia and subfertility.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.
