ABSTRACT: To evaluate changes in corneal sensitivity, tear film function, and ocular surface stability in patients after cataract surgery.
This hospital-based prospective randomized trial included 48 eyes from 30 patients who underwent phacoemulsification. Slit-lamp examination, Schirmer test 1 (ST1), and measurement of corneal sensitivity and tear film breakup time (BUT) were performed for all patients 1 day before and 1 day, 1 month, and 3 months after surgery. In addition, conjunctival impression cytology from the temporal region of the conjunctiva was simultaneously performed.
Corneal sensitivity at the center and temporal incision sites had decreased significantly at 1 day postoperatively (P = .021, P < .001). However, the sensitivity had returned to almost the preoperative level 1 month postoperatively. The mean postoperative ST1 results were no different from preoperative values. On the other hand, BUT results had decreased significantly at 1 day postoperatively (P = .01) but had returned to almost the preoperative level 1 month postoperatively. Mean goblet cell density (GCD) had decreased significantly at 1 day, 1 month, and 3 months postoperatively (P < .001). In addition, decrease in GCD and cataract operative time were highly correlated (r² = 0.65).
The decrease in GCD, which was correlated with operative time, had not recovered at 3 months after cataract surgery. Therefore, microscopic ocular surface damage during cataract surgery seems to be one of the pathogenic factors that cause ocular discomfort and dry eye syndrome after cataract surgery.

ABSTRACT: Transmission of avian-origin influenza A virus (H3N2) to dogs had been reported and since then the H3N2 virus infection across South Korea has been occurred repeatedly in the country's animal clinics and kennels. Dog-to-dog transmission of the virus had also been experimentally demonstrated by direct contact. In this study, immunogenicity and protective efficacy against challenge exposure of the formalin-inactivated H3N2 influenza virus vaccine with a synthetic polymer adjuvant was investigated in dogs. The beagle puppies received two inactivated vaccine injections intramuscularly 2 weeks apart. Serological investigation by a hemagglutination inhibition (HI) test and an ELISA assay indicated that a significant increase in antibody titer was displayed 2 weeks after the second vaccination. Clinical signs, virus shedding and histopathological lesions in the lungs were exhibited in unvaccinated beagle puppies directly challenged through an intranasal route with the virus 2 weeks after the second vaccination. However, the vaccinated animals did not show any clinical signs and showed milder pathological lung lesions and shorter shedding duration with lower loads than controls'. These results indicated that the synthetic polymer-adjuvant avian-origin canine influenza virus (CIV) vaccine had produced antibody response and protection from avian-origin CIV challenge in dogs.

ABSTRACT: Susceptible dogs were brought into contact with dogs experimentally infected with an avian-origin influenza A virus (H3N2) that had been isolated from a pet dog with severe respiratory syndrome. All the experimentally infected and contact-exposed dogs showed elevated rectal temperatures, virus shedding, seroconversion, and severe necrotizing tracheobronchitis and bronchioalveolitis.

ABSTRACT: This study was performed to evaluate the effect of betatricalcium phosphate and poly L-lactide-co-glycolide-coepsilon- caprolactone (TCP/PLGC) membrane in the repair of partial bone defects in canine proximal humerus. Three adult mixed-breed dogs were used during the experimental period. The length of the defect was quarter of the full length of humerus, and width of the defect was quarter of middle diameter of the lateral aspect of humerus. The humeri of each dog were divided into treatment (TCP/ PLGC) and control groups. The defect was covered with TCP/PLGC membrane in treatment group. To evaluate regeneration of the bone, computerized tomography (CT) and histopathologic examination were performed. The radiopaque lines were appeared at the original defect sites in TCP/PLGC group but below the original site in control at 4th week. Radiopacity and thickness of the defect sites, and radiopaque lines were more increased at 8th week than those of 4th week. Histopathologic findings revealed fibrous connective tissue migration into the defect and the migration inhibited the structure of new cortex to be placed in the original level in control whereas new cortex growth was found in the level of original line in TCP/ PLGC group. However, the new cortical bone in the TCP/ PLGC group was thinner and less organized than the adjacent intact cortex, and the amount of new cancellous bones were also scanty. The result suggested that TCP/ PLGC membrane is a good guided bone regeneration material to restore the original morphology of humerus in partial defect.
