The concentration of tartrate resistant acid phosphatase (TRAP) in synovial fluid of normal stifle joint was investigated in order to establish a baseline data to distinguish between healthy joint and joint with injury of cranial cruciate ligament (CCL). Twenty three mixed-breed healthy dogs free from joint diseases (fourteen adult and nine young) were used in this study. The dogs were sedated and synovial fluid was collected from the femoropatellar compartment of stifle joints by direct arthrocentesis. The concentration of TRAP in synovial fluid was determined using the method of Lang. The concentration of TRAP were $0.083{\pm}0.039$ IU/ml in adult dogs, $0.064{\pm}0.023$ IU/ml in young dogs, $0.075{\pm}0.028$ IU/ml in large dogs (>22 kg), $0.076{\pm}0.046$ IU/ml in small dogs (<22 kg), $0.085{\pm}0.036$ IU/ml in neutered dogs and $0.056{\pm}0.022$ IU/ml in intact dogs. The concentration of TRAP in the neutered dogs was significantly (p<0.05) higher than the intact dogs. This data can be used baseline data for a comparison with joint with injury of cranial cruciate ligament.
Health concern of dogs is the most important issue for pet owners. People who have companied the dogs long-term provide the utmost cares for their well-being and healthy life. Recently, it was revealed that the population and types of gut microbiota affect the metabolism and immunity of the host. However, there is little information on the gut microbiome of dogs. Hericium erinaceus (H. erinaceus; HE) is one of the well-known medicinal mushrooms and has multiple bioactive components including polyphenol, β-glucan, polysaccharides, ergothioneine, hericerin, erinacines, etc. Here we tested a pet food that contained H. erinaceus for improvement in the gut microbiota environment of aged dogs. A total of 18 dogs, each 11 years old, were utilized. For sixteen weeks, the dogs were fed with 0.4 g of H. erinaceus (HE-L), or 0.8 g (HE-H), or without H. erinaceus (CON) per body weight (kg) with daily diets (n = 6 per group). Taxonomic analysis was performed using metagenomics to investigate the difference in the gut microbiome. Resulting from principal coordinates analysis (PCoA) to confirm the distance difference between the groups, there was a significant difference between HE-H and CON due to weighted Unique fraction metric (Unifrac) distance (p = 0.047), but HE-L did not have a statistical difference compared to that of CON. Additionally, the result of Linear discriminate analysis of effect size (LEfSe) showed that phylum Bacteroidetes in HE-H and its order Bacteroidales increased, compared to that of CON, Additionally, phylum Firmicutes in HE-H, and its genera (Streptococcus, Tyzzerella) were reduced. Furthermore, at the family level, Campylobacteraceae and its genus Campylobacter in HE-H was decreased compared to that of CON. Summarily, our data demonstrated that the intake of H. erinaceus can regulate the gut microbial community in aged dogs, and an adequate supply of HE on pet diets would possibly improve immunity and anti-obesity on gut-microbiota in dogs.
The purpose of this study was to determine the outcome of distal femoral osteotomy for distal femoral varus and medial patellar luxation (MPL) grade 4 in small-breed dogs. Radiographs and medical records were reviewed to collect data and plan the surgery in small-breed dogs with MPL grade 4. Computed tomography (CT) imaging was also performed in cases of severe bone deformities. Signalment, weight, medial patellar luxation and lameness grade, radiographic bone union, complications, pre- and postoperative femoral varus angle, passive range of motion, static weight bearing distribution and visual analogue scale scores were recorded. Thirteen corrective distal femoral osteotomies were performed with ancillary and additional procedures in 9 dogs; 4 dogs had staged bilateral procedures; and four stifles were suspected to have partial or complete rupture of the cranial cruciate ligament. One stifle underwent patellar groove replacement. The mean ± SD pre- and postoperative femoral varus angles were 109.15°± 3.71° and 96.30°± 2.97°, respectively. Significant improvements in passive range of motion, thigh circumference and visual analogue scale (VAS) scores were observed. There was no reluxation of the patella. This study suggests that distal femoral osteotomy with traditional and additional procedures provided satisfactory outcomes in patient healing and functional recovery in small-breed dogs with excessive femoral varus angles.
Objectives: This study was performed to analyse the effects of Sweet Bee Venom(Sweet BV) on cardiovascular system in the conscious telemetered Beagle Dogs. Methods: All experiments were conducted at Biotoxtech Company, a non-clinical studies authorized institution, under the regulations of Good Laboratory Practice (GLP). Male Beagle dogs of 13-19 months old were chosen for the pilot study and surgical implantation was performed for conscious telemetered Beagle dogs. And after confirming condition of Beagle dogs was stable, Sweet BV was administered 4 times(first: 0.0 mg/kg, 2nd: 0.01 mg/kg, 3rd: 0.1 mg/kg, and forth: 0.5 mg/kg, one time/week) in thigh muscle of Beagle dogs. And blood pressure, heart rate, electrocardiography and clinical responses were measured. Equal amount of normal saline to the Sweet BV experiment groups was administered to the control group. Results: 1. In the analysis of body weight and taking amount, Beagle dogs did not show significant changes. 2. In the clinical observation, responses of pain and edema were showed depend on dosage of Sweet BV. 3. In the analysis of blood pressure, treatment with Sweet BV did not show significant changes in the dosage of 0.01 mg/kg, but in the dosage of 0.1 mg/kg and 0.5 mg/kg, treatment with Sweet BV increased blood pressure significantly. 4. In the analysis of heart rate, treatment of Sweet BV did not show significant changes in all dosage and period. 5. In the analysis of electrocardiography, treatment of Sweet BV was not showed significant changes in all dosage and period. Conclusion: Above findings suggest that Sweet BV is relatively safe treatment in the cardiovascular system. But in the using of over dosage, Sweet BV may the cause of increasing blood pressure. Further studies on the subject should be conducted to yield more concrete evidences.
This retrospective study is designed to compare the clinical results of tibial tuberosity transposition (TTT) and anti-rotation suture (ARS) treatments for medial patellar luxation (MPL). Medical records of 133 dogs were reviewed that had undergone surgical correction of MPL between January 2013 and May 2017. MPL correction was performed on 182 stifles, with TTT and ARS being performed on 101 stifles and 81 stifles. The common dog breeds receiving surgical treatment for MPL were Maltese, Pomeranian, Chihuahua and Poodle. Mean age of dogs with MPL was 32.6 months, and their mean body weight was 4.26 kg. Seventy dogs (52.6%) were male and 63 (47.4%) were female. Of the 182 stifles with MPL, grade II, III and IV were 18.7%, 72.0% and 9.3%. Total complications after TTT and ARS were recorded in 16.8% and 29.6%. Major complications after TTT and ARS were recorded in 5.9% and 12.3%, minor complications after TTT and ARS were recorded in 10.9% and 17.3%. The risk of complication and reluxation rate after TTT were significantly lower than that for ARS (p < 0.05). However, the rate of reluxation among dogs treated by ARS (1.2%) for grade II MPL was significantly lower than that for dogs treated by ARS (8.6%) for grade III MPL (p < 0.05). The TTT group had a shorter recovery period after surgical intervention than that in the ARS group (p < 0.001). In conclusion, TTT had a significantly lower incidence of complication and a shorter recovery period than ARS. However, ARS for grade II MPL appears to be a good surgical option for reducing the rate of reluxation after surgery. These results of this study could be used to provide therapeutic guidelines for surgical MPL correction in small-breed dogs.
Heishui county, located in northwest Sichuan province, southwestern China, is an endemic area of zoonotic visceral leishmaniasis (VL) and is the most intractable area. VL is never destroyed in it. Asymptomatic dogs (Leishmania parasites have been diagnosed but clinically healthy) are considered to be a potential reservoir host in zoonotic VL area, and most can lead to infection of individuals, that is a new challenge for controlling VL in humans. The present study aimed to assess the Leishmania infection rate of asymptomatic dogs in Heishui county. Total 105 asymptomatic domestic dogs were gathered from 4 districts in Heishui county to investigate the infection rate with serological and molecular methods based on ELISA and kinetoplast minicircle DNA(kDNA) PCR, respectively. Out of 105 dogs, 44 (41.9%) were positive by more than 1 method; 21 (20.0%) were positive by ELISA, and 30 (28.6%) were positive by kDNA-PCR. Our study showed that Leishmania infection of domestic dogs which is clinically healthy is prevalent in the studied district, and the asymptomatic dogs infected by Leishmania may be the primary reason for the prevalence of visceral leishmaniasis in the area.
This study was conducted to evaluate whether plasma homocysteine levels were related to obesity or its contributing factors (e.g., lipids, insulin, glucose, glucagon, and fructosamine) in dogs without systemic diseases such as diabetes or renal failure. For achieving our study goal, 100 client-owned dogs without systemic diseases were enrolled in this study. Fasting glucose concentration; lipid profile (i.e., total triglycerides [TG], total cholesterol [TC], highdensity lipoprotein cholesterol [HDL-C], and low-density lipoprotein cholesterol [LDL-C]); and fructosamine, insulin, and glucagon levels were determined. The dogs were subdivided by the body condition score (BCS). The median levels of homocysteine were considerably higher in obese dogs than in lean and normal dogs. Interestingly, not only was homocysteine positively associated with the level of HDL-C, but also found to have a significant positive association with TG, TC, plasma glucagon levels, and fructosamine. In contrast, LDL-C, fasting glucose and insulin did not show any association with homocysteine. The findings presented, suggest that elevated levels of homocysteine may play a biological role in obesity in dogs.

The object of the present study was to compare abnormal serum canine pancreas-specific lipase results and pancreatic ultrasonographic findings in dogs with pancreatitis. Pancreatitis is a common disease in dogs that is difficult to diagnose. The noninvasive diagnostic procedures, including a serum canine pancreatic-specific lipase (cPL) test and ultrasonographic changes in the pancreas, can be considered for the diagnosis of canine pancreatitis in clinical practice. A retrospective study was performed to assess pancreatitis in dogs. Forty client-owned dogs were suspected to have pancreatitis, which was confirmed by abnormal serum SNAP cPL results. Abdominal ultrasound examinations were also performed. The present study investigated the distribution of clinical signs associated with pancreatitis, and the dogs were divided into two groups: group 1 (clinical signs compatible with pancreatitis; n = 30) and group 2 (no clinical signs; n = 10). Based on this study, an abnormal result on the SNAP cPL assay can still present as a normal pancreas through an ultrasonographic examination, and a normal health status can identify the status of pancreatic ultrasonographic abnormal lesions. Therefore, for dogs with suspected pancreatitis, it is important to repeat an ultrasonographic evaluation. There is no significant difference between clinical symptoms and ultrasonographic changes in the pancreas.
This study was performed to investigate the hemodynamic changes which occur after occlusion of coronary artery and relation to reperfusion arrhythmias(RA) which occur when occlusion materials were removed form coronary artery in dogs. The occlusion of coronary artery was designed by temporary ligation of left circumflex branch of coronary artery during 30 minutes in 16 dogs. During occlusion of coronary artery, cardiac output(CO), mean aortic pressure (mAP), aortic systolic pressure(ASP), aortic diastolic pressure(ADP). left ventricular systolic pressure(LVSP), left ventricular maximum dp/dt (LV max. dp/dt) and left ventricular end-diastolic pressure (LVEDP) were measured. The occurrence of RA were observed for 5 minute after reperfusion by explained of ligation. As a results, cardiac arrest occurred in 4 dogs during occlusion of coronary artery, and RA was not observed in 5 dogs while it was seen in 5 dogs when explained ligation(reperfusion) after 30 minutes, the rest 2 dogs occurred temporary tachycardia. In hemodynamics changes, LVSP decreased by 10.9% and LV max. dp/dt by 5.4 % in comparison to control value which not ligated coronary artery, and LVEDP increased by 73.3%. The CO/min and mAP also decreased by 10.7% and by 11.3% expectedly. In the relationship to occurrence RA and hemodynamics changes, the LVSP and LV max. dp/dt at the time of occlusion in the RA group decreased by 11.9% and 0.8% in comarison to the control value while the decrease was 7.7% and 10% in the non-RA group. But the LVEDP in creased by 109.1% in the RA group while the decreased was 44.6% in the non-RA group. Referring CO/min, the drop was 8.8% in the RA occurrence group and 12.9% in the non-occurence group. These parameters of LVEDP, LV max. dp/dt, and CO were significant difference(p<0.05). The mAP also decreased by 11.9 in the RA group and by 9.8% in the non-RA group, but these defference were not the significant difference.
The purpose of this study was to evaluate the effect of chitosan-calcium sulfate mixture on early bony consolidation in osteodistracted dogs. The experimental group was divided into 3 groups: saline group(Control), chitosan group(Group CH) and chitosan-calcium sulfate mixture group(Group CH+CS). Four dogs were allocated to each group and classified into B week observation subgroups and 5 week observation subgroups, respectively. Two dogs were allocated to each subgroup. The lateral surface of the left mandibular body was exposed in the subperiosteal plane and vertical osteotomy was carried out on the mandibular body. An external distraction device was applied to the mandibular body. Mandibular distraction was started 5 days after the osteotomy at a rate of 1 m per day for a total of 10 w distraction for 10 days. After completion of distraction, chitosan, chitosan-calcium sulfate and saline were injected into the distracted zone of the group CH, group CH+CS and control. The external device was left in place for 3 or 5 weeks to allow for bony consolidation. Serial radiographs were carried out every week. Two dogs of each group, six dogs in total, were sacrificed at 3 weeks, and the other six dogs at 5 week after distraction. Bone specimens of the distracted mandibles were taken for histologic examination. New bone was not noted in the distracted zone of 3 week observation subgroups in the control and group CH. However, new bone was developed in the group CH+CS with a narrow fibrous interzone in the area of the distracted zone. While osteogenesis was mild in the margin of the distracted Bone of 5 week observation subgroup in the control, new bone was noted much in the group CH and group CH+CS. However, osteogenesis was noted more significantly in the group CH+CS than that of group CH. In conclusion, chitosan-calcium sulfate mixture was more effective on early bony consolidation in distraction osteogenesis
