Detection of multiple etiologies and comparison and investigation of pathological changes in small and large intestine lesions of dogs
Aim: This study was conducted for the purposes of investigating pathological
changes in intestines of dogs, detecting prevalence of them and determining
their role in being the cause of death.
Materials and Methods: The intestines of 100 dead stray dogs were
examined in macroscopic, histopathologic, microbiologic, and parasitic
aspects. Immunohistochemical stainings were also performed for parvovirus
and distemper diseases.
Results: Hemorrhages in 61, ulcers in 8, parasites in 36, invagination in 14 and
foreign objects in 2 of dogs were determined. Microscopically, histopathological
findings such as degeneration, necrosis and desquamation in epithelium,
bacteria colonies, hyperaemia, hemorrhages, fibrosis and inflammatory cell
infiltrations in propria, degeneration, dilatation and hyperplasia in crypts,
and depletion in lymphoid tissues were observed and their severity were
scored. Canine parvovirus positive IHC reaction was found in 90 out of 100
dogs and canine distemper virus positive reaction was found in 27 dogs,
also. Microbiologically, Campylobacter spp., Escherichia coli, Enterococcus
spp., Streptococcus spp. are found in 58 dogs. Histopathologically, 29 acute,
51 chronic, 15 lymphocytic and plasmacytic enteritis; 5 acute, 10 chronic, 6
diffuse and 20 idiopathic mucosal colitis were diagnosed,respectively.
Conclusion: It has been emphasized that alimentary tract diseases and
lesions, mainly Parvoviral enteritis, are the first-degree cause of death in
street dogs gathered in shelters. Generally, mixed infections were found, and it
has been noticed that the lesions are increased, or primary lesions are masked
according to participation period of secondary factors to infection
Heart rate variability and heart rate turbulence in patients with chronic obstructive pulmonary disease
Background: In chronic obstructive pulmonary disease (COPD) patients, functional and structural
changes of the respiratory system greatly influence cardiovascular autonomic functions.
Determining autonomic balance may be important in understanding the pathophysiology of COPD
and useful clinically in the treatment of COPD patients. Heart rate variability (HRV) and heart
rate turbulence (HRT) are useful tools in assessing the autonomic neurovegetative function. Our
aim in this study was to evaluate the HRV and HRT variables in COPD patients. Twenty five
moderate to severe COPD patients and 25 healthy subjects were included in this study.
Methods: Pulmonary function tests and echocardiographic examination, arterial blood gases
analysis were performed, HRV and HRT analysis were assessed from a 24-hour Holter recording.
Results: When HRV and HRT parameters were compared, COPD patients had significantly
decreased sNN50 total, pNN50, SDANN, SDNN, SDNNI, rMSDD in time domain HRV parameters,
and the values of the HRT onset was significantly less negative in COPD patients. Although
the values of the HRT slope were lower in COPD patients, there was no significant difference
between the two groups. We also found a correlation between HRT and HRV parameters.
Conclusions: In addition to HRV parameters, HRT onset was significantly different in
COPD patients. In our opinion, the combination of HRV variables and HRT onset may be
simple and elegant ways of evaluating cardiac autonomic functions. New investigations of
HRT and HRV in COPD patients have a potential importance for improving risk stratification
and therapeutic approaches, and understanding the autonomic outcomes of the disease process
The effect of ellagic acid on the repair process of periodontal defects related to experimental periodontitis in rats
Objective: This study aims to evaluate the effect of ellagic acid (EA) by measuring the levels of alveolar bone resorption and inflammatory and oxidative stress markers in the periodontal tissues and serum on the periodontal repair process related to experimental periodontitis in rats. Methodology: Forty Wistar rats were divided into four study groups as follows: Group 1=healthy control (n=10); Group 2=EA control (15 mg/kg)(n=10); Group 3=periodontitis (n=10); Group 4=periodontitis+EA (15 mg/kg) (n=10). The periodontitis model was established by ligating bilateral mandibular first molars for 14 days. Then, rats were given normal saline or EA for another 14 days by gavage administration. Serum and gingiva myeloperoxidase (MPO) activity, 8-hydroxydeoxyguanosine(8-OHdG), and glutathione (GSH) levels were analyzed by ELISA. İmmunohistochemical analysis was used to detect Interleukin (IL)-6, IL-10, and tumor necrosis factor-alpha (TNF-α) immunoreactivities in the periodontal tissues. Alveolar bone loss (ABL) and attachment loss (AL) was evaluated by histomorphometry analysis. Results: ABL and AL were statistically higher in group 3 than in groups 1, 2 and 4 and in group 4 than in groups 1 and 2 (p<0.05). MPO activities in gingival tissue and serum were significantly increased in group 3 compared to groups 1 and 2 (p<0.05). Significantly higher serum GSH levels, lower gingiva, and serum 8-OHdG levels, and MPO activity were observed in group 4 compared to group 3 (p<0.05). Rats with periodontitis (group 3) expressed significantly higher immunoreactivities of IL-6 and TNF-α and lower IL-10 immunoreactivity compared to those other groups (p<0.05). IL-6 and TNF-α immunoreactivities significantly decreased and IL-10 immunoreactivity increased in group 4 after the use of EA compared to group 3 (p<0.001). Conclusions: Our findings showed that EA provides significant improvements on gingival oxidative stress and inflammatory markers and alveolar bone resorption in the repair process associated with experimental periodontitis. Therefore, EA may have a therapeutic potential on periodontitis
Mullerian inhibiting substance expression in papillary thyroid cancer
SummaryObjectiveTo examine the expression of Mullerian inhibiting substance (MIS) in papillary thyroid cancer.Materials and methodsThe MIS expression was examined by studying the immunohistochemistry in deparafinized sections prepared from tissue blocks of patients who were diagnosed with papillary thyroid cancer, as given in the pathology archive records (n = 23).ResultsIn all the cases studied, 50% (n = 10) showed strong staining and 50% showed moderate staining. The percentage of staining was found to be 94.2 ± 3.1% in strongly stained cases and 92.2 ± 2.1% in moderately stained cases. Normal thyroid tissues neighboring the tumor did not display any staining.ConclusionThe MIS expression can be used as a significant tool in differential diagnosis of papillary thyroid cancer and also to shed light on its etiopathogenesis

Modified outpatient dexamethazone, cytarabine and cisplatin regimen may lead to high response rates and low toxicity in Lymphoma
Objective: Our purpose was to investigate the efficacy of and establish a toxicity profile for a modified regimen of dexamethasone, cytarabine and cisplatin (DHAP) for lymphoma outpatients. Subjects and Methods: Fifty-one lymphoma patients, 26 with Hodgkin's disease and 25 with non-Hodgkin's lymphoma, were included. The patients' median age was 32 years (range: 17-61). Twenty had progressive/refractory disease and 31 relapsed disease. Twenty-five were in clinical stage I/II and 26 in clinical stage III/IV before the initiation of salvage chemotherapy. DHAP consisted of dexamethasone (40 mg i.v. on days 1-4), cytarabine (2 g/m(2) i.v. as 3-hour infusion on days 2 in the evening and 3 in the morning) and cisplatin (35 mg/m(2) as 2-hour infusion on days 1-3) were administered every 21 days. A total of 154 cycles of modified DHAP were administered, with a median of 3 cycles per patient (range: 2-4). Results: The main toxicity was myelosuppression. WHO grade III-IV neutropenia and grade III-IV thrombocytopenia were observed in 27 (52.9%) and 21 (41%) patients, respectively. The overall response rate (85% for Hodgkin's disease and 95% for non-Hodgkin's lymphoma) was 88.3% (39.2% complete response and 49.1% partial response). Conclusion: The results showed that this outpatient schedule of DHAP was well tolerated and an effective salvage regimen
