JOURNAL FREE ACCESSWe performed two experiments to determine the effect of intrauterine administration of chitosan acetic acid solution (chitosan solution) on the conception rate after synchronization of estrus-ovulation. In the first experiment, the cows were given intrauterine administration of chitosan solution at a dose of 200 mg/50 ml. Seven days after the chitosan solution administration, the cows were given variant CIDR-synch (chitosan CIDR group : n=106). The conception rate of cows with CIDR-synch only (control group : n=101) was 44.5%, whereas the rate for chitosan-treated cows was 59.4% (P<0.05). In the second experiment, the subjects were postpartum Holstein cows, which showed no clear estrus until after parturition. The cows were given intrauterine administration of a chitosan solution. Rectal examinations were performed 7-14 days after administration, and cows with corpus luteum were given intramuscular injections of PGF2α (PG) to induce estrus, and were artificially inseminated (chitosan group : n=27). The conception rate of cows with PG only (n=29) was 37.9%, whereas the rate for chitosan-treated cows was 74.1%. The rate for chitosan-treated cows was thus significantly higher than that for cows with PG only (P<0.01). These findings suggest that with intrauterine administration of the chitosan solution before synchronization of estrus-ovulation, conception rates improved.View full abstractDownload PDF (314K) -

JOURNAL FREE ACCESSBetween June and November 2011, four young Saanen goats in the same farm presented with ataxia. A necropsy revealed that all the goats showed muscle atrophy in both hind limbs, and one of the animals had severe cerebellar atrophy. A histopathological examination revealed central chromatolysis in the red vestibular nuclei and ventral horn neurons of the affected animals. In the cerebellum, atrophy of the granular cell layer and molecular layer was evident, and a loss of Purkinje cells was also observed. The proliferation of gemistocytic astroglia was observed in the thalamus. Intense axonal degeneration was obvious in the nerve fibers of the spinal ventral root and sciatic nerve, and was accompanied with the infiltration of foamy macrophages. Group atrophy of the muscle fibers was seen in the skeletal muscles of the femoral regions of both hind limbs. Immunohistochemical analysis on the cerebral white matter, thalamus, and cerebellar white matter demonstrated chronic proliferation of vimentin- and GFAP-positive astroglia. Significantly decreased serum copper levels were demonstrated in three of the four affected animals. On the basis of these findings, the four young goats were diagnosed as delayed enzootic ataxia caused by copper deficiency.View full abstractDownload PDF (3400K) -

JOURNAL FREE ACCESSIt is generally difficult to isolate Akabane virus (AKAV) and detect its gene and antigen from abnormal calves and cattle with neurological symptoms. Using ten clinical samples of Akabane disease obtained in Yamaguchi Prefecture from September 2011 to January 2012, the usefulness of real-time RT-PCR (rRT-PCR) in diagnosis of the disease was examined. AKAV genes were mainly detected from the brain stem, spinal cord and cerebellum of nine cattle with neurological symptoms and an abnormal calf by rRT-PCR. Positive correlations were found between the AKAV gene quantity detected in the central nervous system and the severity of the inflammatory reaction, between AKAV gene quantity and intensity of positive immunoreactivity, and between severity of inflammatory reaction and intensity of positive immunoreactivity. It was suggested that rRT-PCR is useful for more sensitive and accurate diagnosis of Akabane disease.View full abstractDownload PDF (265K)

JOURNAL FREE ACCESSTreating incurable diseases in pets has become possible as a result of the development of veterinary medical technology. It may seem that there would be few owners of companion animals who would wish to treat their animals with the help of highly developed veterinary technology at the actual time of a veterinary consultation. A questionnaire was administered to the owners, and a qualitative and quantitative analysis was carried out using the KJ-Method to investigate the owners' wishes with respect to the treatment of previously incurable diseases in their pets. It was found that many owners wished their pets to undergo analgesic treatment first, but some wanted their pets to be treated using the latest highly developed veterinary technology. They also hoped that veterinarians would be humane and provide them with a proper explanation of the procedures. In addition, they had difficulties regarding the propriety of the treatment. Although theoretical saturation required supplementary examination, this research showed the potential of qualitative analysis such as the KJ-Method as a solution for veterinary medical problems related to human psychology.View full abstractDownload PDF (456K) -

JOURNAL FREE ACCESSA 1-year-old spayed female Golden Retriever had presented with swelling on the right-hand side of the bridge of the nose and gingiva and alveolar mucosa of the right maxillary canine tooth two months previously. The swelling was alleviated by draining the fluid and administering antibiotics. Ten days before the referral, the swelling recurred in the same area and the dog was referred to the Animal Medical Center, Gifu University. The parchment crepitation on the swollen gingiva and alveolar mucosa of the right maxillary canine was palpated at initial admission. Radiographic and computed tomography examination revealed the buccal alveolar bone of the right maxillary canine in the transmitted image, and a cyst was located around the alveolar bone. The tissue obtained through biopsy was diagnosed as an odontogenic cyst lined with a stratified squamous epithelium. The dog was therefore diagnosed presumptively with a cyst, and extirpative surgery was performed one week later. The swelling was directly cut and exfoliated to clear the alveolar bone. The wall of the cyst was exposed and surgically removed. Since the cyst did not include tooth substance and there was neither significant displacement nor mobility of the teeth around the lesion, the tooth was not extracted. The surgically removed lesion was diagnosed as an odontogenic keratocyst lined with a stratified squamous epithelium with parakeratosis. Based on this case, it is evident that odontogenic keratocysts can be treated with tooth-conserving surgery as long as they are discovered and treated early.View full abstractDownload PDF (719K)

JOURNAL FREE ACCESSIn the present study, the prevalence of B. canis antibody was serologically examined in 484 dogs at Tokushima Prefectural Animal Welfare Center using the microplate agglutination test. In total, 2.5% (12/484) of the serum samples were found to be positive. The positive rates in stray dogs, house dogs, and breeding dogs were found to be 2.6% (8/310), 2.3% (3/133), and 2.4% (1/41), respectively. Control of the B. canis infection in a seropositive dog, in two dogs living with the seropositive dog and in the previous owner was successfully achieved through collaboration among medical services, the veterinary services and the local government.View full abstractDownload PDF (253K)
