The expression of c-fos and c-jun in the brain of the rat after capsaicin treatment was investigated by in situ hybridization, dot blot hybridization and immunocytochemical methods. Adult male Sprague-Dawley rats[200g] were used for this study. The first set of rats received a single subcutaneous injection of capsaicin[50mg/Kg] dissolved in 10% Tween-80 and 10% ethanol in saline. The rats were decapitated 1, 3, 5, 10, 24, 72 hours and 1 week after capsaicin treatment. The control set of rats were treated with saline instead of capsaicin. In situ hybridization and dot blot hybridization were carried out. O1igonucleotide probe complimentary to c-fos mRNA sequences were used for this study and labeling of oligonucleotides was accomplished using the DNA tailing kit. The expression of c-fos mRNA on the nucleus of neurons in in situ hybridization was observed throughout the brain, and was especially abundant in the olfactory cortex, nucleus of diagonal band of Broca, habenular nuclei, periaqueductal gray, parabrachial nucleus, entopeduncular nucleus, ventral posterolateral nucleus of the thalamus and cerebellum. Compared to the control rats, c-fos mRNA were increased 24 hours after capsaicin injection and gradually decreased after 72 hours, returning to the normal control level 1 week after capsaicin injection. c-fos mRNA was detected only 1 week after capsaicin injection in the various areas of the brain. The fos protein-like immunoreactivity was initially somewhat decreased at 24 hours, but increased at 72 hours and reactions was maximally observed at 1 week after capsaicin treatment. But Jun protein immunoreactivity was not increased, on the contrary, it was even decreased both in numbers of reactive cells and immunoreactivity 1 week after capsaicin injection. From the above results, c-fos gene expression was pronounced in the nucleus concerned with pain, olfaction and taste such as VPL nucleus of the thalamus, olfactory cortex and parabrachial nucleus, in the limbic system concerned with stress and emotion such as nucleus of diagonal band of Broca, periaqueductal gray and habenular nucleus, in the structure concerned with somatic motor function such as entopeduncular nucleus and cerebellum. Also, the c-fos gene was activated by the capsaicin early in the course of effects, then the fos protein increased as a results of c-fos activation. On the other hand, c-jun did not respond to capsaicin treatment early in the course, but Jun protein decreased late in the course of capsaicin effects.

Pathologists and others have been calling the serous cystadenoma of the pancreas "microcystic cystadenoma", following Compagno and Oertel's proposal in l978 because it usually consists of innumerable small cysts (less than 2cm). However, unilocular or predominantly macrocystic types of serous cystadenoma have been occasionally reported. Therefore, they present a difficulty in precise preoperative and intraoperative diagnosis for their simi1ar gross appearance to other cystic lesions of the pancreas. We discovered two cases of macrocystic and unilocular serous cystadenomas of the pancreas which were lined by cuboidal to flattened epithelial cells. They contained PAS positive and D-PAS negative intracytoplasmic glycogen granules. The unilocular, macrocystic and microcystic patterns may represent a morphologic spectrum of a pancreatic neoplasm. So we propose to use the term "serous cystadenoma" rather than microcystic cystadenoma.

PURPOSE: To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. MATERIAL AND METHODS: 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. RESULTS: The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of delamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the roedial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). CONCLUSION: Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may helpful in avoiding various ocular complication during ethmoid surgery.

5.Association of Perfectionism with Job Search Behavior and Career Distress among Nursing Students in South Korea
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2022;31(1):27-35
Purpose:
Understanding the influence of perfectionism among senior nursing students is imperative for addressing strategies to reduce career distress and enhance job search behavior. The purpose of this study was to identify perfectionism types among senior nursing students in South Korea. Differences in career distress and enhanced job search behavior for each perfectionism type were compared.
Methods:
A cross-sectional, descriptive design was employed. A total of 211 nursing students completed surveys for Perfectionism, Job Search Behavior, and Career Distress. Cluster analysis and post-hoc tests were conducted.
Results:
A total of 80.1% were classified into the perfectionism group, including adaptive (49.8%) and maladaptive (30.3%). Maladaptive groups showed the highest discrepancy between standards and their perceived achievements as well as career distress. Job search behavior was the highest in the adaptive perfectionism group but the lowest in the non-perfectionism group.
Conclusion
Nursing educators should consider career coaching customized by each perfectionism type to improve job search behavior among nursing students.
6.Herpes Zoster Ophthalmicus-Induced Oculomotor Nerve Atrophy
Annals of Optometry and Contact Lens 2024;23(2):81-84
Purpose:
To present a case of oculomotor nerve atrophy complicated by herpes zoster ophthalmicus (HZO).Case summary: A 68-year-old man with a history of type 2 diabetes and dyslipidemia complained of diplopia and deviation in left eye. On examination, visual acuity was 20/25 in right eye and 20/20 in left eye. Prism and alternate cover tests revealed right exotropia and hypertropia in the primary position. Examination of ductions and versions showed limitation of adduction and depression in the right eye. On detailed history taking, we found that his symptoms started after suffering HZO on right side about 2 years ago. He was prescribed antiviral agents from a dermatology clinic and was told that all symptoms would improve after medication so he didn't undergo an ophthalmologic examination at that time. Magnetic resonance imaging confirmed that diffuse atrophy of oculomotor nerve in cistern along with atrophic changes of medial rectus and inferior rectus muscles in right eye. A diagnosis of strabismus complicated by HZO-induced oculomotor nerve atrophy was done.
Conclusions
Ophthalmoplegia secondary to HZO may not be self-limiting and have a poor prognosis resulting in cranial nerve atrophy. A detailed imaging investigation of extraocular muscle and cranial nerves along with thorough history taking are required for proper diagnosis and better prognosis.

Methods:
The mixture of IB and DJ extracts was analyzed for its total flavonoid content (TFC), total polyphenol content (TPC), and radical scavenging activities. Gastric lesions were induced by treating rats with 1 mL of a solution containing 60% ethanol and 150 mM HCl.The rats were then divided into 5 groups: CON (normal control), HEC (treated with 150 mM HCl-60% ethanol and distilled water), IBE (treated with 150 mM HCl-60% ethanol and IB extract at 350 mg/kg body weight [BW]), ID30 (treated with 150 mM HCl-60% ethanol and a mixture of IB and DJ extracts in a 7:3 ratio at 350 mg/kg BW), and DJE (treated with 150 mM HCl-60% ethanol and DJ extract at 350 mg/kg BW).
Results:
The ID30 group exhibited significantly higher TFC, TPC, and radical scavenging activities than the groups treated with single extracts. This group also showed a notable decrease in the formation of gastric lesions and preservation of gastric wall mucus. In addition, the serum levels of the inflammatory marker tumor necrosis factor (TNF)-α were significantly lower in the ID30 group than in the HEC group.
Conclusion
The antioxidants present in the ID30 mixture effectively reduced oxidative stress and reactive oxygen species, mitigating gastric mucosal irritation induced by alcohol and acid. Furthermore, the mixture inhibited gastric acid secretion and inflammatory marker expression, such as TNF-α, preventing tissue damage. These findings suggest that the ID30 mixture is a potential preventative treatment for gastritis.
