This study investigated the influence of 0.00584% hydrocortisone aceponate spray (HCA; Cortavance Virbac SA, Carros, France) on blood serum cortisol levels and peripheral blood CCR4+ CD4+ T-lymphocyte levels in dogs with atopic dermatitis. Patients were randomly divided into group I (N=8) and group II (N=8). The dogs in group I were sprayed with HCA on the affected skin once a day for three weeks. The dogs in group II were treated once a day for 3 days followed by no treatment for 4 days for a total of three weeks. For the dogs in group I and group II the CADESI-03 scores before and after use of HCA showed significant reduction (P<0.01). The postcortisol level after the use of HCA in group I showed 36.0% decrease and showed significant suppression (P<0.01). By comparison, the use of HCA on group II did not show decrease in postcortisol levels. There was a tendency of suppression for hypothalamus—pituitary gland—adrenal gland system, but it was not serious influence. In addition, there was no influence on peripheral blood CCR4+ CD4+ lymphocytes percentage in dogs in group I after treatment with HCA.Corrigendum to “Influence of a Diester Glucocorticoid Spray on the Cortisol Level and the CCR4+ CD4+ Lymphocytes in Dogs with Atopic Dermatitis: Open Study”

SummaryP-selectin, also known as CD62P, GMP140 or PADGEM, is present in platelet a-granules and endothelial cell Weibel-Palade bodies and is very rapidly expressed on the surface of these cells on activation. In this study, an anti P-selectin monoclonal antibody (LYP20) was used, in tandem with flow cytometry, to identify activated platelets at the site of induced vascular trauma or in peripheral blood. Moreover, electron microscopy was performed to characterize sites of vascular trauma and quantify the number of adhering platelets. The same induced vascular trauma was observed to result into animals responding in 2 different ways (Group I, Group II) following the degree of platelet activation. Five rats, out of 14 with induced vascular trauma, had more than half of their circulating platelets expressing P-selectin when drawn at the site of the trauma (67.4% ± 3.44) or in peripheral blood (78.5% ± 2.5) (Group I). In the remaining 9 animals a much smaller proportion of circulating platelets expressed P-selectin when assayed from trauma sites (18% ± 3.34) or in peripheral blood (18.0% ± 4.30) (Group II). Enhanced P-selectin expression by circulating platelets in Group I, compared to Group II, appears to be linked to the degree of activated platelets adhering at sites of trauma (171 ± 15 × 103 platelets versus 48 ± 31 × 103 platelets per mm2). In the 5 control animals, that were not operated on, platelets expressing P-selectin when drawn at the site of a mock trauma (7.0% ± 1.84) or in the peripheral blood (11.2% ± 3.30) showed little activation. In addition, no platelet adhesion was seen on the vascular bed of these animals. Results from this study show that analysis of P-selectin (CD62P) expression, in circulating platelets, is a valuable and rapid marker of platelet activation following severe vascular trauma induced in rats. However, activated platelets were not detected to the same extent in the peripheral blood of all animals having undergone vascular trauma. It is conceivable that platelets, depending on the degree of activation, may be actively sequestered in organs and prevented from circulating. Alternatively, P-selectin may be rapidly endocytosed, or not expressed, by activated circulating platelets depending on the type of agonists implicated in vivo activation.

We have determined the sites of action of endothelin-1 (ET) in the lamb pulmonary circulation. The influence of cyclooxygenase inhibition and baseline vasomotor tone on ET effects was also studied. Lungs of 14 lambs (6-9 wk of age, 12.1 +/- 0.6 kg body wt) were isolated and perfused with blood. Group I lungs (n = 5) were untreated, group II lungs (n = 5) were treated with indomethacin to inhibit cyclooxygenase, and group III lungs (n = 4) were treated with indomethacin and a thromboxane A2 analogue, U-46619, to elevate vasomotor tone. All lungs were perfused with constant flow in zone 3, with left atrial and airway pressures being 8 and 6 cmH2O, respectively. We measured pulmonary arterial pressure and, by the micropuncture servo-null method, pressures in 20- to 50-microns diameter subpleural venules, both before and after each dose of ET was infused (50, 100, 250, and 500 ng/kg). Group I lungs, with high baseline vasomotor tone, exhibited a biphasic response to ET; 50-100 ng/kg of ET dilated both arteries and veins, whereas 500 ng/kg of ET constricted both arteries and veins. In group II lungs with low vasomotor tone, all doses of ET caused constriction of arteries only. In group III lungs (indomethacin treated with elevated vasomotor tone), 50-100 ng/kg of ET caused dilation of arteries and veins, whereas 500 ng/kg of ET induced constriction, this time only in arteries. We conclude that ET has both dilator and constrictor effects in arteries and veins of isolated, perfused lamb lungs. ET-induced arterial and venous dilation is dependent on initial vasomotor tone but not on cyclooxygenase metabolites.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract The aim of the study was to evaluate the effects of rehabilitation in patients with chronic obstructive pulmonary disease (COPD) using the Kinect system during stationary rehabilitation. The study included 68 patients with COPD (35 men, 33 women, mean age 61.3 ± 3.7). The subjects were randomly assigned to one of the two experimental groups described below. Group I included 34 patients – non‐participants in Kinect training. Group II included 34 patients – participants in Kinect training. In all patients before and after rehabilitation physical fitness was assessed using the Senior Fitness Test (SFT). The Xbox 360 and Kinect motion sensor were used to carry out virtual reality training. In group I, statistically significant improvements in SFT performance were observed. Patients in group II also showed statistically significant improvement in physical fitness in all attempts of the SFT. Virtual rehabilitation training in patients with COPD seems to be a practical and beneficial intervention capable of enhancing mobility and physical fitness.

Background/Aim. Elevation in adduction is the most common pattern of vertical strabismus, and it is mostly treated with surgery. The results of weaking of inferior oblique muscle are very changeable. The aim of this study was to evaluate binocular vision using sensory tests before and one and six months after the surgery. Methods. A total of 79 children were divided in two groups: the first, with inferior oblique muscle of overaction (n = 52), and the second with dissociated vertical deviation (DVD), and primary inferior oblique muscle overaction (n = 27). We tested them by polaroid mirror test (PMT), Worth test at distance and near, fusion amplitudes on sinoptofore, Lang I stereo test and Wirt-Titmus stereo test. We examined our patients before and two times after the surgery for vertical strabismus. Results. Foveal suppression in the group I was found in 60.5% of the patients before, and in 56.4% after the surgery. In group II Foveal suppression was detected in 64.7% of the patients before, but in 55.6% 6 months after the surgery with PMT. Worth test revealed suppression in 23.5% of the patients before, and in 40.7% after the vertical muscle surgery. Parafoveal fussion persisted in about 1/3 of the patients before the surgery, and their amplitudes were a little larger after the surgery in the group I patients. Lang I stereo test was negative in 53.9% before and 51.9% after the surgery in the group I, and in 48.2% of the patients before and after the surgery in the group II patients. Wirt-Titmus stereo test was negative in 74.5% of the patients before and in 72.9% after the surgery in the group I, but in the group II it was negative in 70.8% before and in 68.0% of the patients 6 months after the surgery. Conclusion. Binocular responses were found after surgery in 65.7% of the patients the group I and in 55.6% patients the group II. There was no significant difference between these two groups, but binocular responses were more often in the patients of the group I.

The study was designed to observe the effects of surgical stress on serum level of cortisol in patients undergoing surgical treatment and to find out any differences in hormonal response between elective and emergency surgical procedures. A total number of 60 male subjects aged between 18 and 45 years were included in the study. Of them, 20 were healthy control (Group I), 20 underwent elective surgical treatment (Group II) and emergency surgical interventions were applied in rest 20 subjects (Group III). Study Groups were further divided into subgroups A (preoperative samples were collected 1- hour before operation), B (postoperative samples were collected 1-hour after the end of the operation) and C (postoperative samples were collected 24-hours after operation).Serum cortisol level was estimated by invitro-immunolytic test.Statistical analysis was done by paired, unpaired ‘t' test and regression analysis. The preoperative mean serum cortisol concentration in elective surgical cases was almost similar to that of healthy control. On the contrary, in the emergency surgical cases, a significantly increased mean cortisol level were observed (I vs IIIA and IIA vs IIIA; P < 0.05). The serum cortisol concentrations were increased both in elective and emergency surgical cases after operations but the magnitude of rise was more marked in emergency group of patients (IIB vs IIIB; P < 0.05). Therefore, this study reveals that surgical intervention causes increase in serum cortisol which is more marked in emergency procedure.

Objective. Evaluate if different bleeding patterns associated with the use of the levonorgestrel intrauterine system (LNG-IUS) are associated with different uterine and endometrial vascularization patterns, as evidenced by ultrasound power Doppler analysis.Methodology. A longitudinal study, with each subject acting as its own control was conducted between January 2010 and December 2012. Healthy volunteers with a history of heavy but cyclic and regular menstrual cycles were enrolled in the study. Ultrasonographic examination was performed before and after six months of LNG-IUS placement: uterine volume, endometrial thickness, and subendometrial and myometrial Doppler blood flow patterns have been evaluated.Results. A total of 32 women were enrolled out of 186 initially screened. At six months of follow-up, all subjects showed a reduction in menstrual blood loss; for analysis, they were retrospectively divided into 3 groups: normal cycling women (Group I), amenorrheic women (Group II), and women with prolonged bleedings (Group III). Intergroup analysis documented a statistically significant difference in endometrial thickness among the three groups; in addition, mean pulsatility index (PI) and resistance index (RI) in the spiral arteries were significantly lower in Group I and Group III compared to Group II. This difference persisted also when comparing—within subjects of Group III—mean PI and RI mean values before and after insertion.Conclusions. The LNG-IUS not only altered endometrial thickness, but—in women with prolonged bleedings—also significantly changed uterine artery blood flow. Further studies are needed to confirm these results and enable gynecologists to properly counsel women, improving initial continuation rates.

The objective of the study was to characterize the term Doka and to capture morphological changes in teat to find out the relationship between Doka and onset of estrus in Murrah buffaloes (Bubalus bubalis). The Murrah buffaloes maintained at of Livestock Research Centre (LRC), ICAR-NDRI, Karnal were classified into two groups based on the lactation number for the study of Doka characteristics. In group I, twenty animals up to 3rd lactation were incorporated, whereas thirty animals from 4th to 5th lactation were included in group II. The period when buffaloes showed teat engorgement was called as Doka period, is the local term used by the farmers in North India that can be taken as a visual sign for prediction of estrus. The length and diameter of teats, before and after milking were measured, for both the groups during morning and evening milking and subsequently analyzed. The present study confirmed that the teat diameter (mm) before milking during Doka was significantly (plessthan0.05) higher as compared to pre Doka period in both the groups (group-I - 37.01 ±2.13 vs 28.42 ±1.64, group-II - 53.49 ±2.82 vs 41.096±2.16). The teat diameter (mm) during Doka period after milking was significantly (plessthan0.05) more in both the groups (group-I - 26.65 ±1.26 vs 24.44 ±1.16, group-II - 39.27 ±2.41 vs 35.31 ±2.17) as compared to pre Doka period. So, it can be concluded that the changes in teat diameter can safely be considered as a sign of Doka and the forthcoming heat in Murrah buffaloes. However, the difference in teat length between different stages of Doka was found to be non significant.

Background: Sedentary behavior is one of the leading modifiable risk factors for cardiovascular disease and all-cause mortality. Physical exercise exerts beneficial physiological effects on cardiovascular fitness. Different grades of physical exercise have different effects on cardiovascular health. Objective: To compare the effect of moderate and high intensity exercise training on heart rate variability (HRV) in sedentary office workers. Methods: This study was conducted on 40 healthy sedentary volunteers aged between 20-40 years of both the genders. Participants were distributed into two groups of 20 subjects each. Subjects of group I and group II performed moderate intensity and high intensity exercise respectively on bicycle ergometer for 12 weeks. Their 5- minute ECG recording was done by three channel physiograph, and frequency domain indices of HRV and heart rate (HR) were analyzed and compared before and after exercise training. Their blood pressure was also recorded and compared before and after exercise training. Independent sample t-test and paired sample ttest were used for statistical analysis. Results: HF, systolic and diastolic blood pressure reduced significantly after exercise in group II (p=0.015, 0.005, and 0.015 respectively) while HR and LF/HF ratio reduced in both group I and group II (p=0.000 for HR, and 0.034, 0.001 for LF/HF). The decrease in HR was greater after high intensity exercise than moderate intensity exercise (p= 0.025). Conclusion: Parasympathetic activity improves after moderate and high intensity exercise but improvement is more after high intensity exercise training. Therefore, high intensity exercise training is more beneficial than moderate intensity exercise training. J Bngladesh Soc Physiol 2021;16(1): 16-23
