Lakshmi, M. Santhi ; Rao, T.S. Chandrasekhara ; Rajalakshmi, K. ;
Korean Journal of Veterinary Research, volume 53, issue 2, 2013, Pages 69~71
DOI : 10.14405/kjvr.2013.53.2.069
The maxillary sinus appeared first among the sinuses of the skull at 92 days of prenatal stage. The early formation of frontal sinus was observed at 157 days in the cranial most part of the frontal bone while the early formation of palatine sinus was observed at 170 days. A total of five fontanelles were observed in prenatal skulls of buffalo. The largest and unpaired fontanelle was anterior fontanelle. The mastoid and sphenoidal fontanelle were paired. The ossification of anterior fontanelle was first observed at 164 days. All the fontanelles were ossified completely prenatally.

DOI : 10.14405/kjvr.2013.53.2.073
The aim of this study was to produce a simple and inexpensive technique for estimating the obturator foramen area (OFA) from young calves based on the hypothesis that OFA can be extrapolated from simple linear measurements. Three linear measurements - dorsoventral height, craneocaudal width and total perimeter of obturator foramen - were obtained from 55 bovine hemicoxae. Different algorithms for determining OFA were then produced with a regression analysis (curve fitting) and statistical analysis software. The most simple equation was OFA (
) = [3,150.538 + (
)] - [147,856.033/DH] (where CW = craneocaudal width and DH = dorsoventral height, both in mm), representing a good nonlinear model with a standard deviation of error for the estimate of 232.44 and a coefficient of multiple determination of 0.846. This formula may be helpful as a repeatable and easily performed estimation of the obturator foramen area in young bovines. The area of the obturator foramen magnum can thus be estimated using this regression formula.

The present study was planned to evaluate the bioequivalence of two commercial formulations of enrofloxacin, which have been marketed as 10% injectable solution after intramuscular administration at a single dose of 2.5 mg/kg body weight to 12 clinically healthy goats The study was carried out on the basis of crossover design. The two formulations were: Baytril as a reference product and Spectrama Vet as a test product. The plasma concentrations of enrofloxacin were measured by high performance liquid chromatography (HPLC) with UV detector. The pharmacokinetics of that data was performed using non-compartmental analysis. The maximum plasma concentration (
), time to reach peak concentration (
), area under concentration-time curve (AUC), elimination half-life (
) were 1.14 and
, 0.79 and 0.83 h, 5.70 and
, 5.19 and 5.39 h for Baytril and Spectrama Vet, respectively. The 90% confidence interval for the mean ratio of
and AUC were 94.72-116.2, 87.88-97.16 and 86.44-118.72%, respectively. These values falls within the European Medicines Agency bioequivalence acceptance range of 80-125% for both
and AUC and between 75-133% for
. In conclusion, Spectrama-Vet is bioequivalent to Baytril and both products can be used as interchangeable drug in veterinary medicine practice.

DOI : 10.14405/kjvr.2013.53.2.083
Field efficacy of enterotoxigenic Escherichia coli-specific phage (
) as a feed additive was evaluated in weaning piglets. Fifty-four piglets at 3-4 weeks old were allocated in three different groups and two of them were fed with bacteriophage at different concentrations (
feed, respectively) for 30 days. Body weight and feed intake were measured at 10 days interval and body condition and fecal score were inspected every day. Based on the measurement, feed conversion rate (FCR) and average daily gain (ADG) of each group during 30 days were analyzed. The analysis suggests that the bacteriophage may help the improvement of FCR and ADG at
of bacteriophage feeding group in 30 days. A result from analysis of fecal score indicates that the bacteriophage also may help to relieve the intermittent diarrhea in post-weaning stage. Those results suggest that bacteriophage might help the growth of piglets in post-weaning stage.

DOI : 10.14405/kjvr.2013.53.2.089
This study was performed to investigate the effect of Nei Guan (PC-6) moxibustion stimulation on artificial bradycardia of dogs. Xylazine was injected for inducing bradycardia. Rectal temperature, systolic blood pressure, respiratory rate, heart rate were recorded every 10 minutes for 120 minutes. Systolic blood pressure significantly increased on 40 min (p < 0.05) after xylazine injection, compared with those of control group. Heart rate significantly increased on 40 min (p < 0.01), 50 min (p < 0.01), 60 min (p < 0.01), 70 min (p < 0.01), 80 min (p < 0.01), 100 min (p < 0.01), 120min (p < 0.01) after xylazine injection, compared with those of control group. In conclusion, moxibustion of Nei Guan (PC-6) showed recovery effect in xylazine induced bradycardia in dogs.

The study was carried out to evaluate and compare the immune responses in mice experimentally infected with either wild-type or isogenic mutants of Salmonella enterica serovars Enteritidis (SE), Salmonella Typhimurium (ST) and Gallinarum (SG). The mutant strains were constructed by allelic replacement of some virulence-associated genes in the wild-type strains. Seven-week-old female BALB/c mice were orally or intraperitoneally inoculated by injecting bacterial suspension. To evaluate the immune responses, enzyme-linked immunosorbent assay (ELISA) and enzyme-linked immunospot (ELISPOT) assay were conducted with serum and fecal samples. As a result, the mice group infected orally with the SE mutant strain showed the highest level of specific IgA-secreting splenocytes, compared to the other groups. The peritoneally injected groups showed the greater levels of IgG1 than the orally injected groups, which was in a good agreement with the previous studies. In addition, the mutant infected groups had the similar secretion levels of antibodies with the wild-type infected groups. These results demonstrated that the SE mutant strain elicited humoral immune response as much as wild-type, implying that it can be useful as a delivery vehicle as well as a candidate of a live attenuated vaccine.

The objective of this study was to investigate the calf death and analyse the causes of the mortality by based on medical records and autopsy findings during 10 years in a large dairy farm. Total of 1,361 calf born and 146 calf dead during the invested period. Mortality rate was 10.7% and showed the big difference by year-specific mortality from 2.8% (4 calves) to 19.2% (28 calves). The highest rate of mortality was 1 week age (18.5%, 27 calves) and followed by 2 week age (11.6%, 17 calves) and mortality of more old calf tended to be reduced. The death less than 4 weeks and 8 weeks of age of the entire mortality accounted for 41.1% (60/146 calves) and 70.0% (102/146 calves), respectively. Causes of calf death were digestive diseases (53.4%), respiratory diseases (17.1%), musculoskeletal disease (8.2%), and systemic disease (8.2%) in order. Specific causes of calf death was highest in enteritis (43.2%), followed by pneumonia (14.4%), sepsis (8.2%) and fractures (3.4%). Seasonally, most of calf death happened in winter (48.6%) and then fall (21.2%). This results showed that enteritis and pneumonia are the main reason of calf death but other reasons were involved in calf death on the based on autopsy finding. On going research relating factors of calf mortality is needed.

Cancers are mainly sustained by a small pool of neoplastic cells, known as cancer stem cells or tumorinitiating cells. These cells possess the ability to self-renew and proliferate, and are thus able to form the tumor. In the present study cells that correspond to cancer stem cells in mammary and liver cancers in animals were identified by the expression of CD133, CD44, CK7, and OCT4 using immunochemistry. As a result, we found with CD133+ and CD44+ cancer stem cell-like phenotypes in mouse and canine hepatocellular carcinoma and canine mammary gland tumors. However, CK7+ and OCT4+ cells were not identified in animal mammary and liver cancer. CD133+ and CD44+ cells are wellknown stem cell lines and play key roles in development and metastasis in human cancer. These findings suggest that cancer stem cells are involved in animal tumorigenesis and may provide insight into mechanisms in cancer development as well as cancer diagnostics.

Infection with Helicobacter (H.) pylori is strongly associated with duodenal and gastric ulcers. Substantial epidemiological data has revealed that high rates of H. pylori infection might be related to high rates of gastric cancer. In this study, a medicinal herbal extracts were examined and screened for anti-H. pylori activity. Seventy percent ethanol was used for herbal extraction. For anti-H. pylori activity study, the inhibitory zone tests with 74 herbal compounds were conducted. As the results, thirteen compounds including Cinnamomi Cortex, Magnoliae Cortex and Meliae Fructus were revealed strong anti-H. pylori activities.

Canine Subcorneal pustular dermatosis (CSPD) represents a sterile, superficial, pustular skin disease of unknown cause but may be a variant of pemphigus foliaceus. A 7-year-old, intact female, mixed dog presented with 3-month history of pruritic multiple pustules and crusts. Direct smears from intact pustules revealed numerous nondegenerate neutrophils, some acantholytic cells, and bacterial culture was negative. Histologic examination of lesional skin showed subcorneal pustules filled with neutrophils and acantholytic cells. The direct immunofluorescence tests stained with IgG, IgA, IgM, C3 were negative. Oral administration of dapsone (1 mg/kg/q8h) was initiated and it was reduced to 1 mg/kg/q12h with good control of the lesions.

A 5-year-old, castrated male, Maltese was presented with history of acute flaccid paralysis. The dog was presented with sudden loss of muscle tone and involuntary movements of hind limbs. Neurologic examination revealed reduced postural reaction in the bilateral hind limbs. MRI of brain showed moderate hydrocephalus, but other examination results were normal. Based on the characteristic episodes and examination results, canine cataplexy was suspected. Treatment was initiated with clomipramine as cataplexy control. Clinical signs resolved with 3-month medication. This case demonstrates therapeutic diagnosis of cataplexy. To the author's knowledge, this is the first report of cataplexy treating with clomipramine.

To report multiple congenital ocular defects in a Bedlington terrier dog aged 2.5 months with blindness. Routine ophthalmic examinations were performed for the clinical signs. Menace responses and cotton ball test were absent in both eyes (OU), but pupillary light reflexes were normal in OU. Slit lamp biomicroscopy reveled corneal dystrophy, posterior subcapsular cataract, microphthalmia in OU and lenticular coloboma in the right eye. In indirect ophthalmoscopy and ultrasonography, retinal detachment and posterior lenticonus were shown in OU. It is the first report of lenticular coloboma and posterior lenticonus in a Bedlington terrier dog.

To report retinal image of in a 6-year-old male castrated poodle dog with a 2-month history of nyctalopia using optical coherence tomography (OCT). Ocular reflexes were present in both eyes and slit lamp examination showed anterior subscapular cataract in the right eye. There were fundus abnormalities in both eyes similar to retinal degeneration. Scotopic electroretinograms (ERGs) revealed significantly subabnormal amplitudes and prolonged implicit time, whereas photopic ERGs were better maintained, although far from normal. OCT of affected dogs revealed generalized retinal thinning much more than a normal age-matched dog. Therefore, OCT scanning is considered to be a useful method for retinal evaluation in dogs with retinal degeneration.
