The complete blood count and serum biochemical parameters are essential tools for diagnosis and monitoring of physiological and disease conditions in dogs. These parameters may be affected by the breed and age of dogs. This study aimed to compare the changes of complete blood count and serum biochemical parameters according to the increasing age in 156 Sapsarees. In this study, the Sapsarees were clustered into ten age groups: four to six months, seven to nine months, ten to twelve months, one year, two years, three to four years, five to six years, seven to eight years, nine to ten years, and, eleven to twelve years old. In the result of the complete blood count, the total red blood cell count (P<0.001), hematocrit (P<0.001), and hemoglobin (P<0.001) values were significantly increased from 4~6 months to 2 years old Sapsarees. While the mean corpuscular volume (P<0.001) and mean corpuscular hemoglobin (P<0.001) values were significantly increased from 4~6 months to 3~4 years old. The mean corpuscular hemoglobin concentration was significantly (P=0.037) increased from 4~6 to 10~12-month-old Sapsarees. Total white cell count was significantly (P<0.001) decreased from 1 year to 9~10 years old. The result of differential white blood cell count showed that neutrophil count was significantly (P<0.001) increased from the age 4~6 months to 11~12 years old Sapsarees, whereas, lymphocyte (P<0.001), monocyte (P<0.001), and eosinophil (P=0.042) counts were significantly decreased from 7~9 months to 7~8 years, 4~6 months to 9~10 years, 3~4 to 5~6 years old, respectively. In the serum biochemistry result, the creatinine concentration was significantly (P<0.001) increased from 4~6 to 10~12 months, but significantly (P=0.006) decreased from 7~8 to 10~12 years old. Phosphate concentration was significantly (P<0.001) decreased from 3~4 to 9~10 years old, but significantly (P=0.021) increased from 9~10 to 11~12 years old. Calcium concentration significantly (P<0.001) decreased from 10~12 months to 11~12 years old. Total protein concentration significantly (P<0.001) increased from 4~6 months to 2 years old. While concentrations of albumin (P=0.004) and globulin (P<0.001) was significantly increased from 4~6 months to 3~4 years old, and from 4~6 months to 11~12 years old, respectively. The alkaline phosphate concentration was significantly (P<0.001) decreased from 4~6 months to 2 years old. We found that there are differences in the hematological parameters in relation with the increasing age in Sapsaree breed.

Hot tub lung has been described as a pulmonary illness associated with exposure to nontuberculous mycobacteria,mainly hot bathtub water contaminated with Mycobacterium avium complex (MAC) and hence the name. Although not entirely clear, its etiology has been thought to involve either an infection or a hypersensitivity pneumonitis secondary to MAC. Herein, we describe 2 female patients (60 and 53 years old) admitted to our hospital with hot tub lung, and both of whom worked in a public bath. Both women were initially admitted following several months of exertional dyspnea and cough. The patients had been working as body-scrubbers in a public bath for several years. Their chest CT scans showed bilateral diffuse ground-glass opacities with multifocal air-trappings and poorly defined centrilobular nodules in both lungs. Pathological findings from lung specimens revealed small non-necrotizing granuloma in the lung parenchyme with relatively normal-looking adjacent alveoli. Discontinuation of working in the public bath led to an improvement in symptoms and radiographic abnormalities, without antimycobacterial therapy.

Objectives Previous studies suggest that the cannabinoid receptor 1 (CNR1) gene could be an important candidate gene for schizophrenia. According to linkage studies, this gene is located on chromosome 6q14-q15, which is known to harbor the schizophrenia susceptibility locus (locus 5, SCZ5, OMIM 803175). The pharmacological agent delta-9-tetrahydrocannabinol (${\Delta}$-9-THC) seems to elicit the symptoms of schizophrenia. The association between CNR1 polymorphisms and schizophrenia is actively being investigated, and some studies have linked the AAT-trinucleotide repeats in CNR1 to the onset of schizophrenia. In this study, we have investigated the association between the AAT-trinucleotide repeats in CNR1 and schizophrenia by studying schizophrenia patients and healthy individuals from Korea. Methods DNA was extracted from the blood samples of 394 control subjects and 337 patients diagnosed with schizophrenia (as per the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria). After polymerase chain reaction amplification, a logistic regression analysis, with age and gender as the covariates, was performed to study the variations in the AAT-repeat polymorphisms between the two groups. Results In total, 8 types of trinucleotide repeats were identified, each containing 7, 8, 10, 11, 12, 13, 14, and 15 repeats, respectively. $(AAT)_{13}$ allele was most frequently observed, with a frequency of 33.6% and 31.6% in the patient and control groups, respectively. The frequency of the other repeat alleles in the patient group (in the decreasing order) was as follows : $(AAT)_{13}$ 33.6%, $(AAT)_{14}$ 21.6%, $(AAT)_{12}$ 18.5%, and $(AAT)_{7}$ 11.1%. The frequency of the repeat alleles in the control group (in the decreasing order) was as follows : $(AAT)_{13}$ 31.6%, $(AAT)_{14}$ 24.5%, $(AAT)_{12}$ 17.2%, and $(AAT)_{7}$ 11.6%. However, there were no significant differences in the AAT-repeat polymorphisms of the CNR1 gene between the patient group and the control group. Conclusions Although our study revealed no significant association of the AAT-repeat polymorphism of the CNR1 gene with schizophrenia, it will serve as a good reference for future studies designed to examine the cannabinoid hypothesis of schizophrenia.

The purpose of this study was to evaluate feasibility of Vertical Multileaf Collimator for determination of irradiation size using Vertical Multileaf Collimator and lead block to determine 4 different irradiation shape in case of Co-60 gamma-ray and 6 MV X-ray. We chose ion chamber, glass dosimeter and EBT chromic film to compare with Vertical Multileaf Collimator results and lead block results. In case of Co-60 gamma-ray and 6 MV X-ray, the central axis point dose normalized at reference field of lead block with ion chamber results for Vertical Multileaf Collimator were estimated higher than lead block about 5.1%, 4.2%. In case of Co-60 gamma-ray, the central axis point dose normalized at reference field of lead block with glass dosimeter results for Vertical Multileaf Collimator were estimated higher than lead block about 2.2%, 7.8%, 7.2%, 4.0% for reference, circle, triangle, cross field, respectively. In case of 6 MV X-ray, the central axis point dose normalized at reference field of lead block with glass dosimeter results for Vertical Multileaf Collimator were estimated higher than lead block about 6.7%, 6.2%, 3.8%, 6.2% for reference, circle, triangle, cross field, respectively. The results of EBT chromic film, Vertical Multileaf Collimator of penumbra size for all irradiation shape was smaller than lead block of those size that 2.0~3.5 mm for Co-60 gamma-ray, 0.5~1.0 mm for 6 MV X-ray. The results from this study, radiation treatment volume that results in shielding block can be minimized. In addition, during radiation treatment for 2, 3-dimensional radiation therapy using a Vertical Multileaf Collimator of this survey can be used to determine variety of irradiation fields.

Objectives : This study examined the association between depression and survival time in terminal cancer patients admitted to the palliative care unit. Emotional problems are important for terminal cancer patients in the palliative care unit, and evaluation of patients' depression plays an important role in treatment planning. Methods : From October 2015 to August 2018, we conducted a retrospective study of 291 terminal cancer patients admitted to a palliative care unit at a university hospital and evaluated depression with PHQ-9 at admission. Of the 291 patients, 146 (50.2%) completed PHQ-9 but 145 (49.8%) were not evaluated due to loss of consciousness or rejection. Results : 4-week survival rate in the Kaplan-Meier survival analysis were 45.4% in the non-depressed group (PHQ-9<10) and 18.7% in the depressed group (PHQ-9≥10). According to the severity of depression, in the Cox proportional hazard model, the risk of mortality in moderate, moderately sever and severe group was 2.778, 1.882 and 3.423 times higher than minimal group, respectively. Conclusions : Of the patients with terminal cancer who were admitted to the palliative care unit, the survival time was shorter in the depressed group than in the non-depressed group. Further research is needed to determine if treatment of depression increase the survival in terminal cancer patients.

Hypoadrenocorticism results from the deficient adrenal gland production of glucocorticoids or mineralocorticoids. Fludrocortisone have been used for the management of hypoadrenocorticism in dogs. But desoxycorticosterone pivalate (DOCP) have been administered for management of hypoadrenocorticism in dogs since several years because of the equivalent effect of fludrocortisone, and lessening of owner and patient's effort. The therapy of DOCP was evaluated in 14 dogs diagnosed with hypoadrenocorticism based on clinical signs, an electrolyte imbalance, and the results of an adrenocorticotropic hormone stimulation test. DOCP was administered at 25-day intervals at an initial dose of 2.2 mg/kg. The dogs were monitored for clinical signs and serum electrolyte, blood urea nitrogen, and creatinine concentrations every 25 days. Fludrocortisone was an effective treatment in dogs overall; however, a change to DOCP was necessary in 7 dogs because of adverse effects or poor responses. Another 7 dogs were treated with DOCP from the first time. A total of 14 dogs were treated with DOCP. Clinical signs and electrolyte imbalance resolved completely in 12 dogs. However, mild clinical signs, such as shivering, remained in 2 dogs, and 4 dogs required regular supplementation with prednisone. Improvements in clinical signs and electrolyte imbalance were significantly better after treatment with DOCP than with fludrocortisone. The results suggest that DOCP may be a better choice than fludrocortisone for the management of hypoadrenocorticism in dogs.

Purpose: Recently multi-modal imaging system has become widely adopted in molecular imaging. We tried to fabricate animal-specific positioning molds for PET/MR fusion imaging using easily available molding clay and rapid foam. The animal-specific positioning molds provide immobilization and reproducible positioning of small animal. Herein, we have compared fiber-based molding clay with rapid foam in fabricating the molds of experimental animal. Materials and Methods: The round bottomed-acrylic frame, which fitted into microPET gantry, was prepared at first. The experimental mice was anesthetized and placed on the mold for positioning. Rapid foam and fiber-based clay were used to fabricate the mold. In case of both rapid foam and the clay, the experimental animal needs to be pushed down smoothly into the mold for positioning. However, after the mouse was removed, the fabricated clay needed to be dried completely at $60^{\circ}C$ in oven overnight for hardening. Four sealed pipet tips containing $[^{18}F]FDG$ solution were used as fiduciary markers. After injection of $[^{18}F]FDG$ via tail vein, microPET scanning was performed. Successively, MRI scanning was followed in the same animal. Results: Animal-specific positioning molds were fabricated using rapid foam and fiber-based molding clay for multimodality imaging. Functional and anatomical images were obtained with microPET and MRI, respectively. The fused PET/MR images were obtained using freely available AMIDE program. Conclusion: Animal-specific molds were successfully prepared using easily available rapid foam, molding clay and disposable pipet tips. Thanks to animal-specific molds, fusion images of PET and MR were co-registered with negligible misalignment.
