The purpose of this study was to assess the sugars contents of home meal replacement (HMR) products currently sold in Korea. This study surveyed and examined the sugars contents in 835 popular HMRs (294 ready-to-eat foods; RTE, 499 ready-to-cook foods; RTC, 42 fresh-cut vegetables; FCV) through the nutrition labels. The average price, weight and energy content of 835 HMR products were 3,917.5 Korean won, 336.0 g, and 522.7 kcal, respectively. The sugars content per product was significantly higher in the RTCs (13.4 g) and RTEs (10.3 g) than that in the FCVs (4.2 g) (P<0.001), and the percentage of energy from sugars was 9.7% for the RTEs, 10.2% for the RTCs, and 8.7% for the FCVs without any significant difference. The sugars contents of 9 RTE types were in the order of side dishes (34.3 g), sunsik (22.5 g) and hamburgers (12.1 g) per package. The percentage of energy from sugars was highest in side dishes (28.1%), followed by kimchi (24.9%), sunsik (17.2%), and hamburgers (10.6%). Among 14 RTC types, the sugars contents were in the order of hot dogs (52.9 g), tteokbokki (30.4 g) and noodles (21.2 g) per package. The percentage of energy from sugars was the highest at 22.9% for sauces, followed by side dishes (17.3%), porridges (14.4%), instant stews (14.3%), and hot dogs (13.1%). Strategies and practices are needed to reduce the sugars contents of HMR producers and the sugars intakes of HMR consumers.

The study of present study was to determine the valuable laboratory tests for the differential diagnosis of lead poisoning in dogs. Sixteen mongrel dogs were divided into 2 experimental groups (A and B) and a control group (C). The A and B groups were administered orally 2 mg and 20 mg of lead per kilogram of body weight for 49 days, respectively. In addition to clinical observation, blood, urine and hair samples were collected on appointed day and examined for hematological changes, lead content of serum, whole blood and hair, and urinary $\delta$-aminolevulinic acid concentrations. All dogs were necropside on 49th day and examined for the lead content and histological changes of organs. The results obtained were summarized as follows: The group B showed digestive and nervous signs, and weight loss. The group A showed no significant hematological changes except polychromatophilla on the 7th day. But group B showed polychromatophilia as well as mild anemia and nucleated erythrocyte on the 7th and 35th day. Basophlic stippling erythrocytes were observed in some of the group B on the 14th day. The lead content of whole blood was increased significantly in both A and B groups on the 21the day. The urinary $\delta$-aminolevulinic acid content was increased in both A and B groups on the 7th day. The hair lead content of A and B groups was increased significantly on the 49th and 21th day, respectively. The lead contents of organs including liver, kidney, spleen, muscle and bone were increased significantly in group B. Histopathologic changes were characterized by hemorrhages, necrosis and intranuclear inclusion body in the epithelial cells of convoluted tubles of kidney, cloudy swelling and degeneration and/or necrosis of liver, enlargement of Virchow-Robin space, and swelling of endothelial cells and hyperplasia of the pericytes of brain. From these results it may be concluded that examination of nucleated erythrocyte/polychromatophilia, urinary $\delta$ -aminolevulinic acid, and whole blood and hair lead contents is a reliable clinico-pathological diagnostic methods, and that examination of the Virchow-Robin space, endothelial cells and pericytes of brain as well as intranuclear inclusion body in the epithelial cells of convoluted tubles of kidney is valualble postmortem diagnostic methods for lead poisoning in dogs.

Canine pyometra generally occurs in intact female dogs of more than four years of age. However, in rarely cases, pyometra can occur in young bitches. In the present report, two cases of pyometra in thirteen and eighteen months of age were presented. In both cases, absent of vaginal discharge represented that both patients had closed-cervix pyometra and diagnosis was somewhat complicated. In complete blood count, elevated level of leukocyte with left shift was found in both cases. Serum chemistry analysis showed elevation of alkaline phosphatase in both cases. Additionally, mild elevation of aspartate transferase and total protein were also found in $2^{nd}$ case. Radiographic and ultrasonographic findings show the enlargement of uterus and accumulation of fluid contents inside the uterine lumen. Ovariohysterectomy followed by antibiotics and anti-inflammatory drugs for post-surgery medication was performed for treatment. After a week, both patients fully recovered. To reduce mortality of pyometra in young intact female dogs, radiography or ultrasonography should be indicated immediately in the bitches showing severe infectious inflammation.

This paper proposes an improved deep learning method based on small data sets for animal image classification. Firstly, we use a CNN to build a training model for small data sets, and use data augmentation to expand the data samples of the training set. Secondly, using the pre-trained network on large-scale datasets, such as VGG16, the bottleneck features in the small dataset are extracted and to be stored in two NumPy files as new training datasets and test datasets. Finally, training a fully connected network with the new datasets. In this paper, we use Kaggle famous Dogs vs Cats dataset as the experimental dataset, which is a two-category classification dataset.

Human growth hormone (hGH) forms antibody by repeated administration. The present study investigated to confirm formation of antibody by repeated subcutaneous administration of hGH for two months in rats and dogs. In this result, hGH-injected sera were significantly higher than control sera by 1:1,000,000 of dilution factor. After antibody formed sera (anti-hGH sera) and control sera were added to 30 $\mu\textrm{g}$/ml hGR, the complex incubated for overnight at $30^{\circ}C$. Anti-hGH sera decreased hGH contents about 90% compared to control sera. Also, body weight gain conducted decreased about 67% compared to control sera in hypophysectomised rat. Inconclusion, repeated administration of hGH formed antibody because hGH was foreign protein to rats and dogs. And formed antibody of hGH was blocked and decreased many efficacy of hGH, the antibody was proved to be neutralizing antibody. Thus, because neutralizing antibodies were decreased pharmacological effects of hGH, administration more than two months were no significance.

The aim of this study was to identify the awareness of the animal registration system, as well as to determine if there is a difference according to the types of pet attachment of consumers raising companion dogs. For this purpose, 250 data were collected by conducting an online survey and analyzed the data using SPSS 24.0. As a result of the study, pet attachment was identified as a companion attachment and emotional attachment. According to the form of attachment to dogs, the consumer types were categorized into three groups: type of simple cohabitation(25.6%), type of close companion(30.4%), and type of strong bond(44.0%). It was found that there are statistically significant differences in the relationship between the recognition and registration of the animal registration system for each consumer type. In addition, there were statistically significant differences in the perception and preference of the animal registration system depending on the type of consumer. This study has significance in that it suggests the effective direction of developing the consumer-oriented animal registration system.

In this paper, we propose the diagnosis system that can predict pet's state of health for pet lovers lacking a technical knowledge of dog-diseases. The proposed system deduces diseases of dogs from input symptoms by our database constructed with 105 kinds of diseases and symptoms. First, a disease is clustered by ART2, the self-learning method in neural network and secondly, the result values, outputs and the weight values clustered by the algorithm are stored to database. Finally, our system diagnoses the state of health by means of comparing the learned information of diseases with the input vectors of each symptom and the related results of questions on diseases. The correct information of diseases and symptom diagnosing is important to predict the state of health of dogs. Therefore, in this paper, the proposed system can manage symptoms and diseases efficiently by database and ART2. We ask veterinary specialist with the efficiency of our system. As a result, we could confirm the possibility as the auxiliary diagnosis system for dog diseases.

Artesunate, a semi-synthetic derivative of artemisinin, is used primarily as a treatment for malaria. Its effects on the central nervous system, general behavior, and cardiovascular, respiratory, and other organ systems were studied using mice, rats, guinea pigs, and dogs. Artesunate was administered orally to mice at doses of 125, 250, and 500 mg/kg and to rats and guinea pigs at 100, 200, and 400 mg/kg. In dogs, test drugs were administered orally in gelatin capsules at doses of 50, 100, and 150 mg/kg. Artesunate induced insignificant changes in general pharmacological studies, including general behavior, motor coordination, body temperature, analgesia, convulsion modulation, blood pressure, heart rate (HR), and electrocardiogram (ECG) in dogs in vivo; respiration in guinea pigs; and gut motility or direct effects on isolated guinea pig ileum, contractile responses, and renal function. On the other hand, artesunate decreased the HR and coronary flow rate (CFR) in the rat in vitro; however, the extent of the changes was small and they were not confirmed in in vivo studies in the dog. Artesunate increased hexobarbital-induced sleeping time in a dose-related manner. Artesunate induced dose-related decreases in the volume of gastric secretions and the total acidity of gastric contents, and induced increases in pH at a dose of 400 mg/kg. However, all of these changes were observed at doses much greater than clinical therapeutic doses (2.4 mg/kg in humans, when used as an anti-malarial). Thus, it can be concluded that artesunate is safe at clinical therapeutic doses.

This study investigated the effects of dietary Ptecticu tenebrifer powder and canned mixtures on protein digestibility by different breeds of companion dogs (15 Bichons, 15 Malteses, 15 Chihuahuas and 15 Poodles). The mixtures were divided into Diet A, Diet B, Diet C, Diet D, and Diet E, which were supplied from five farms. Twenty-five grams each was mixed with 100 g of each canned food, and a total of 125 g was measured for each breed of dog. The result of component analysis of the mixtures showed the highest protein contents rather than dry matter, crude ash or crude fat. There were statistical significances (p<0.05) in all mixed feeds fed to bichon, maltese, chihuahua and poodle dog. Overall, protein digestibility by the breeds of dog ranged from 87.44% to 97.18%. Result of breed of dog comparison revealed that Diet E by poodle dog had the highest protein digestibility, and the lowest protein digestibility was observed in Diet C by Maltese. In conclusion, the use of dietary Ptecticu tenebrifer powder and canned mixtures did not only increased protein digestibility by different breeds of dog but also maintained normal manure properties.

This experiment was carried out investigate changes in proximate composition, pH, volatile basic nitrogen (VBN), thiobarbituric acid value (TBA) and mineral contents of pure Kaesojoo (PK) and Kaesojoo added medicinal herbs (KMH) during storage period (30 days) at 4$^{\circ}C$ and -18$^{\circ}C$. Two dogs with 12kg live weight were slaughtered to obtain samples from extracts. The results obtained were as follows: Crude fat and ash of KMH were higher than those of the PK, but the moisture and crude protein was higher in the PK (p＜0.001). Proximate composition did not affect cold and frozen storage and storage period. the pH of the PK through all periods. The VBN value of all treatment gradually increased during storage period. That of KMH tend to be lower than PK, all treatment was maintained freshness. The TBA value of all treatment gradually increased during storage period (p＜0.05). Cold storage and PK tend to be higher frozen storage and KMH. Among minerals Ca, K, Mg, Na, P contents of the KMH were higher than those of the PK and the Ca, Mg, Zn contents were significantly changes (p＜0.05) according to the storage period and temperature.
