Abstract
In this study, a rabbit endometritis model was developed to study cow endometritis. In addition, the protective effects of baicalin (a flavonoid) against endometritis were investigated. Clinical symptoms, differential leukocyte counting, uterine secretion smear microscopy and chemical examination, urine testing, and signs of necropsy showed abnormal changes and inflammatory responses in the uterus of rabbits. Histopathological results revealed visible inflammatory exudates and blood spots between intercellular spaces which confirmed that the rabbit endometritis model was successfully developed. Most importantly, these inflammatory signs were partially attenuated with baicalin treatment. The data revealed that the increased body temperature and leukocyte cells, pus, and the detachment of epithelial cells were alleviated with baicalin administration in a dose-dependent manner. Histopathological tissue changes such as inflammatory cells infiltrates, hyperemia, hemorrhages, and shedding of epithelial cells were partially attenuated with baicalin treatment. In addition, the mRNA expression of inflammation-related genes (iNOS, IL-1β, TNF-α, IL-10, IL-4, and IL-6) was significantly altered in RAW264.7 cells after LPS treatment. Further, the phosphorylated protein expression of JNK, p65, and IκBα were significantly reduced with LPS treatment. Intriguingly, baicalin pretreatment reversed the alteration in mRNA expression of inflammation-related genes and significantly reduced the phosphorylation of JNK, p65, and IκBα. In summary, our results suggest that baicalin has protective effects on bacterial-induced endometritis in rabbits that involve the suppression of NF-κB and JNK signaling pathways and pro-inflammatory cytokines.

Abstract
Four different models of infection of chickens with Mycoplasma gallisepticum (MG) were evaluated. Normal or immunosuppressed chicks (10 days old) were infected with the MG Rlow strain via eye and nasal drops or by direct air sac injection. Bacterial load in the lungs was quantified and air sac and tracheal lesion scores, tracheal mucosal thickness and humoral immune responses were assessed. Serum antibody responses were assessed by use of a serum plate agglutination test. Three days post infection (dpi), all immunosuppressed chicks had developed significant respiratory signs. Chicks infected via air sac injection had significant differences in serum antibody and gross lesion scores at 5 dpi. All chicks had developed pathological changes by 7 dpi. Air sac inoculation of immunosuppressed chicks produced more significant (P ≤0.05) lesions, and these birds had the highest bacterial load in the lungs compared with other groups.

Abstract
INTRODUCTION The odontogenic keratocyst (OKC), previously known as keratocystic odontogenic tumor has been the most disputable pathologies of the maxillofacial region. Patients with OKC are often asymptomatic but may present with pain, swelling, or discharge. Despite the aggressive nature, previous literature as early as 1970s reported the fact that parakeratinized OKC can be treated by means of marsupialization alone. PATIENTS CONCERNS The patient had reported with a complaint of pain and swelling in relation with a tooth in mandibular right quadrant. DIAGNOSIS This case report discusses features of a rare, extensive, panmandibular OKC that is only second of its kind mentioned in the literature. INTERVENTION As a usual treatment protocol, marsupialization was attempted first. Immunohistochemical analysis revealed reduced expression of Ki-67 and B cell lymphoma 2 (bcl-2) markers after marsupialization from 2 separate sites. However, due to incomplete resolution in the lower right anterior region, an aggressive approach was taken by curetting it out surgically along with associated teeth and cortical plate followed by application of Carnoy's solution. OUTCOME Postsurgery uneventful healing of the lesion was noted on regular follow-up visits with complete resolution at 40 months. The case has been followed for 10 years with no sign of relapse and reoccurrence. CONCLUSIONS Based on the expression of markers it can thus be concluded that Ki-67 and bcl-2 are site specific and bear strong relationship with the recurrence of OKCs.

Abstract
AIM We present in this paper, the preparation and pre-clinical study of 177Lu-labelled hydroxyapatite for the application in radiation synovectomy of small sized joints. METHODS 177Lu is an adequate radionuclide for therapy, having ability of simultaneously showing therapeutic effects and depicting images. Both hydroxyapatite particulates and 177Lu were prepared indigenously. RESULTS AND CONCLUSION Analysis of the gamma ray spectrum showed the radionuclide purity of 177Lu more than 99%. HA particles were synthesized and characterized by FTIR-ATR and X-ray diffractometry. XRD-Pattern generated by the product indicated that the chief inorganic phase of the sample is hydroxyapatite crystal. FTIR spectrum of HA powder calcined at 800°C for 1h showed all the bands that can be assigned to phosphate and hydroxyl groups in an apatite environment. Ca/P ratio was determined by ICP-OES. The Ca/P ratio of 1.68 determined for HA was about 0.6% above the stoichiometric ratio of 1.67. Particle size distribution pattern was obtained with the help of laser particle size analyzer and results showed that more than 80% of the particles bear the size in the range ideal for radiosynovectomy. 177Lu-labelled hydroxyapatite particulates were prepared with high radiochemical purity and yield. >95% labeling yield was achieved at pH 7. Labeled specie remained stable up to 18 days. In vitro stability >99% remained up to >one half life of 177Lu. Bio-evaluation of the 177Lu-HA particles was carried out by injecting approximate activities of 10 and 5 MBq (in 0.1 mL suspension) as intra-articular injection in the right knee joints of rabbit 1 and 2 respectively. Retention of activity was studied using images of the injected joints with the help of a gamma camera at various intervals. In all images no activity was visible in any organ other than knee joints. The retention of the 177Lu activity was followed for 772 hours (30.01 days). Leakage of activity was also assessed indirectly by estimating the residing time of radiopharmaceutical in the synovium. Half life of 177Lu-HA residing time in the knees was estimated to be 154 hours and 158 hours for rabbit-1 and rabbit-2 respectively. No significant extra articular leakage of the injected activity was observed over a period of one month post injection. Pre-clinical study of 177Lu-labelled hydroxyapatite indicated its potential for application in radiation synovectomy of small joints.
