In the year of 1998 the heads of dog raised in Korea were 1,846,411 and the number of the households raising dogs is 819,112 which means that the heads of pet dog and edible dos were 819,112 and 1,027,299, respectively, because each house raised about one pet dog and one edible dog breeder raised hundreds of dog. in 1998 the number of exported dogs came to 28 heads and that of imported dogs was 296 heads. But edible dog that was slaughtered or processed has not been reported to be exported or imported. It is known that at the Shenyang Xingshan Food Ltd in Shenyang, Chinese, 300,000 heads of dogs were rais-ed slaughtered and processed of dog meat per year, and 20% of them were exported. In Korea the cook of dog meat is a special food culture with a long history. During the Chosun dynasty dog meat had been eaten to be cooked diversely such as Gaejangkuk(a soup) Suyuk(a boiled meat) Sundae(a sausage) Kui(a roasted meat) Gaezim(a steamed meat) Nurumi(a meat roasted or fried to which lot of spice paste are added) Gaesoju(an extract) Musulju(a wine) Musuldang(a sweet cane) Now it is cooked as Bosintang(a soup) Suyuk (a boiled meat) Jeongol (boiled meat mixed with spices vegetables and water on the pot) Duruchigi(boiled meat added spice vegatasble and slightly roasted) Muchim(boiled meat added by spice and mixed) Gaesoju(an extract) with the number of recipes lessened compared with those of the old times. The reason is due to the intervention and criticism from foreign countries. But foreigner's blame for the dog meat is absurd and excessive action because Korea raises exceptional dogs which are edible.

This study was performed to investigate antimicrobial resistance in bacterial isolates obtained from companion dogs in veterinary hospitals and an animal shelter in Incheon. Drug resistance was examined respectively with the isolates of Escherichia coli, Enterococcus faecalis, and Staphylococcus pseudintermedius. The prevalence of drug resistance was calculated for each bacterial species towards 163 E. coli isolates, 156 E. faecalis isolates, and 86 S. pseudintermedius isolates by using selected antimicrobials. E. coli isolates were highly resistant to ampicillin, ciprofloxacin and tetracycline (47.9%, 28.2% and 28.2%, respectively). E. faecalis isolates were highly resistant to quinupristin-dalfopristin, tetracycline, kanamycin, rifampicin (69.8%, 66.0%, 53.8% and 51.9%, respectively). Higher levels of resistance were detected for ampicillin, penicillin, tetracycline, erythromycin, trimethoprim/sulfamethoxazole, telithromycin in S. pseudintermedius isolates (83.7%~52.6%, respectively). Occurrence of methicillin-resistant S. pseudintermedius (MRSP) was confirmed by oxacillin disc diffusion method, resulted in 23.3% occurrence among the S. pseudintermedius isolates (20/86 strains). The occurrence ratio of multidrug-resistance in the isolates of E. coli, E. faecalis, and S. pseudintermedius was 34.5%, 56.9%, and 67.9%, respectively. In this study, higher levels of antimicrobial drug resistance were observed in bacterial isolates obtained from dogs in Incheon. A regular monitoring and surveillance program should be implemented to prevent the emergence and spread of the drug-resistant bacteria carried in companion dogs.

Considerable attention has been focused on the cryopreservation of semen and estrus induction in dog, as consequence of poor productivity caused by long anestrus period, in order to enhance the productivity of youngs and to preserve the breeds. The objectives of this study were to develop a treatment protocol for estrus induction. Fifty infertilie dogs (age 2∼3 years) were selected for the study and divided into three different estrus induction treatment groups. Group 1: dogs (n=15) were given clomifane (0.1 mg/kg) orally for five days at 12 hr intervals. Group 2: dogs (n=15) were given bromocriptine (50 $\mu\textrm{g}$/kg) orally for five days at 12 hr intervals, followed by single injection intravenously of 500 IU GnRH (Group 3, n=20) when pro-estrus occurred. After being treated, the dogs were evaluated for the rates of estrus induction and time interval lapses from treatment to beginning of the pro-estrus. The estrus induction rates were significantly (P<0.05) higher in both group 2 (9/15, 73.3%) and group 3 (16/20, 80.0%) than that of group 1 (9/15, 60.0%), but did not differ in the groups 2 and 3. No differences were observed in the time interval lapses from treatment to beginning of the pro-estrus in group 2 (7.7 ${\pm}$ 1.2 days) and group 3 (6.9 ${\pm}$ 2.0 days), but significantly (P<0.05) shorter than that of group 1 (9.5 ${\pm}$ 2.1 days). In conclusion, the estrus induction rate of dogs treated with a combination of GnRH and bromocriptine was more effective than use of clomifene or bromocriptine only.

It was performed to evaulate the effects of occlusion of mandibular gland and sublingual gland on the mandibular gland in dogs. The occlusion of mandibular gland and sublingual gland was induced by ligature in clinically normal dogs, and ultrasonograpic appearance, hematological changes and histological changes of the mandibular gland were observed daily during 6 days. The results were as follows. 1. The length, width, circumference and area of the mandibular gland in clinically normal dogs were 25.1 mm, 8.4 mm, 56.4 mm and 163.0 $\textrm{mm}^2$ in the left, and 23.4 mm, 8.0 mm, 53.3 mm and 141.6 $\textrm{mm}^2$in the right. 2. The length, width, circumference and area of the mandibular gland were gradually increased after ligature of the salivary duct, and revealed maximum values, as 33.4 mm, 10.9 mm, 73.0 mm and 287.2 $\textrm{mm}^2$, respectively, at 24 hours after ligature, and returned to normal size at 3 days after ligature. 3. The size of the opposite mandibular gland without ligature was also gradually increased until 24 hours, and returned to normal size at 3 days, similar to the changes of the mandibular gland with ligature. 4. There were no significant changes after ligature of the salivary duct in hematological findings. 5. In histopathological findings, the major of glandular alveoli was enlarged at 24 hours after ligature of the salivary duct, and neutrophils and monocytes were infiltrated at 6 days after ligature.

The pharmacokinetics of cyclosporin A (CsA) after single and multiple oral dosing of new CsA self-micro-emulsifying drug delivery system (SMEDDS) in dogs were estimated. A single dose study was performed following a two-way crossover design against six dogs with reference SMEDDS. For a multiple dose study, three dogs were allocated for each drug, and 100 mg of drug was administered daily for 6 days. Whole blood concentration of CsA was analyzed by radio-immunoassay. Both drug showed identical blood concentration profiles in both studies, and no statistical difference was detected in pharmacokinetic parameters. The relative bioavailabilities of test SMEDDS were 91.4% and 89.1%, respectively, in the single dose study and the last day of multiple dose study. Especially, multiple dose study proved the good relationship between C-0/C-2 and AUC for reference SMEDDS, which is an indispensable part of therapeutic drug monitoring. These results suggest newly formulated CsA SMEDDS possibly shows identical pharmacokinetics and pharmacodynamic behaviors in clinical trials.

H3N8 equine influenza virus (EIV) causes respiratory diseases in the horse population, and it has been demonstrated that EIV can transmit into dogs owing to its availability on receptors of canine respiratory epithelial cells. Recently, we isolated H3N8 EIV from an EIV-vaccinated horse that showed symptoms of respiratory disease, and which has a partially truncated nonstructural gene (NS). However, it is not clear that the NS-truncated EIV has an ability to cross the host species barrier from horses to dogs as well. Here, we experimentally infected the NS-truncated H3N8 EIV into dogs, and monitored their clinical signs and viral load in respiratory organs to determine the virus's transmissibility.

The water celery, Oenanthe Javanica DC., is a perennial herb which mostly grows on a damp ground or a streamside. The water celery is widely distributed in Korea, Japan, china, Taiwan, Indonesia, Malaysia and the other countries. From ancient times, the water celery has widely been used for food or medicine. In herbal medicine, the water celery has a medical actions which are defervescence, diuresis, jaundice, edema, hypotensor, haematic, angiostasis, sthenia, appetizer. Recently, studies on the water celery are briskly being conducted. For example, studies on the morphologic property and classifications of origin of the water celery, studies on the chemical constituents of the water celery which contains vitamins, proteins and amino acids, studies on the bio activities of the water celery which contains flavonoids. However, there is not studies of hematological changes in dogs administrated the water celery until now. Consicontly, this study was conducted to observed the hematological changes in dogs administrated excessive amount of the water celery crude juice for a long period. In this studies, all dogs showed significantly decrease of the PCV and Hb, and increase of the WBC, GSH and reticulocytes, but did not significantly change in the RBC, MCV, MCHC and Met-Hb.

Helicobacter species have been identified in or isolated from domestic carnivores, but their prevalence in different population of animals and their clinical significance are still unknown. This study was peformed to evaluate the prevalence of Helicobacter in clinically healthy dogs by urease test, culture, morphological examination and polymerase chain reaction (PCR) technique. Tissue samples from 70 dogs in Kangwon and Kyunggi areas from August 1998 to April, 1999, were examined. The detection rates of Helicobacter by urease activity of tissue-samples were 84.6%, 61.3% and 4.8 % in the fundus, the antrum and the duodenum, respectively. One strain of Helicobacter was isolated from the duodenum. It was identified as H canis by biochemical and morphorogical examination. The detection rates of Helicobacter by histological examination were 92.3%, 79.0% and 4.8% in the fundus, antrum and the duodenum, respectively. Helicobacter organisms were colonized more in the gastric pits than in the surface of epithelium, the gastric gland or the parietal cell. Although most of dogs were colonized with Helicobacter in tissue, gross lesions and specific histopathological lesions caused by Helicobacter in these tissues were not observed. The detection rate of Helicobacter by PCR was 78.6%. The histological examination was more sensitive than urease test, culture or PCR technique for the detection of Helicobacter.

A Spitz (5-years old, castrated male) and a Maltese (9-years old, castrated male) were presented with weight loss, polyuria/polydipsia (PU/PD) and depression. Diabetic ketosis was diagnosed based on clinical signs, physical examinations and screening tests (CBC, serum chemistry and urinalysis). The dogs were treated with NPH initially. However, NPH was inadequate to control blood glucose level due to the short duration of the action (< 5 hours). Because of the poor glycemic control with NPH, the dogs showed diabetic complications including weight loss and cataract. After change to glargine, the duration of insulin action was extended up to 11 hours. As a result, there was significant improvement in clinical signs and serum fructosamine concentrations. This study suggests that glargine is useful as a long-acting insulin in dogs which have poor glycemic control due to the short duration of NPH.

The pharmacokinetics of CJ-50001 (recombinant human granulocyte-colony stimulating factor, developed by R&D center of Cheil Jedang Corp.) were investigated in rats and dogs. The serum concentrations of CJ-50001 were measured by a sandwich enzyme immunoassay. After single intravenous (iv) administration of Cf-50001 to rats at a dose of 5 $\mu$g/kg, the mean terminal half-life and area under the concentration-time curve (AUC) were 0.96 h and 124.497g . h/ml, respectively. After single subcutaneous (sc) administration at the same dose, maximum serum concentration was observed at about 2 hours after administration, and the mean terminal half-life, AUC and the bioavailability were 1.11 h,63.58$\mu$g . h/ml and 51.07%, respectively. In repeated dosing studies, CJ-50001 was administered iv and sc to rats at a daily dose of 5$\mu$g/kg for 7 days. The pharmacokinetic parameters, such as mean AUC and terminal half-life, were no significantly different from those of single administration. Following single iv and sc administration of CJ-50001 to dogs at a dose of 5 $\mu$g/kg, mean AUCs were much higher than those of rats, due to the decreased clearence (CL). After sc administration to dogs, maximum serum concentration was observed at 2~4 hours after administration and the bioavailability was 54.60%.
