Apodemus agrarius has been using for experimental purpose to identifying the route of infection and pathogenesis of korean hemorrhagic fever. However, despite the increasing amount of information being published at present about the physiologic and ecologic characteristics of Apodemus, few data are availalle about the morphologic findings in the brain. The NADPH-diaphorase[NADPH-d] positive neurons, uniquely resistant to toxic insults and neurodegenerative diseases, have been colocalized with neurons in the brain and peripheral tissue containing nitric oxide synthase, which generates nitric oxide, a recently identified neuronal messenger molecule. In this study we used NADPH-d histochemistry to evaluate the distribution of neuropeptide Y-immunoreactive[NPY-IR] cells within neurons which contain nitric oxide synthase. In the cerebral cortex of Apodemus agrarius, NADPH-d positive and NPY-IR neurons were observed in all cortical layers, but they were concentrated in two bands layer II/III and V/VI extending into the subcortical white matter. Double labeling for NADPH-d and NPY showed colocalization of NPY with NADPH-d in numerous neurons of the cerebral cortex. The data obtained showed that about 74-79% of NPY-IR neurons contained NADPH-d in the neocortex and that 77-89% in the allocortex. The number of NPY-IR/NADPH-d positive neurons was about 10-13 per unit area [2,500,000 micrometer] in the neocortex and about 11-25 in the allocortex except retrosplenial cortex. In the retrosplenial cortex, the number of double labeled neurons was about 5 per unit area. NPY-IR and NADPH-d positive neurons were predominantly medium-sized with extended, multipolar or bipolar dendritic branches which belong to fusiform or stellate cell types. A moderately dense network of fine, varicose NADPH-d positive fibers was present throughout all cortical layers.

Purpose: This study evaluated the clinical and radiological outcomes of TFNA (Trochanteric Fixation NailAdvanced; Depuy Synthes) for the treatment of proximal femur fractures. Materials and Methods: This was a retrospective study of 64 patients diagnosed with a proximal femur fracture from January 2019 to November 2019. The patient’s demographic data, preoperatively and postoperatively Koval grade, modified Harris hip score, EQ-5D (Euro-Qol-5 Dimension), sliding and advancement of the blade, radiologic outcome, and complications were investigated. Results: Fifty patients were available for evaluation at one year postoperatively. The patients reported the following: the Koval grade decreased after surgery; the modified Harris hip score decreased from 78.56±8.88 to 72.74±6.59 (p=0.149); the mean EQ-5D decreased from 0.75±0.09 to 0.72±0.06 (p=0.000). Satisfactory reduction was achieved on a postoperative radiographic examination in 47 patients in six months. Complications occurred in seven cases. Conclusion TFNA is considered an appropriate implant for treating intertrochanteric fractures of the femur with a minimum follow-up of one year.

In order to evaluate the effects of a topical application of homologous fibronectin on the healing of skin wounds, we made 2 excisional wounds on the back skin of each rat, applied ointment with or without fibronectin purified from citrated homologous plasma, and evaluated the effect according to wound size and microscopic findings. Excised lesions treated with carrier alone, but the difference was significant only in the early phase of wound healing, 2 and 3 days, according to wound size and microscopic changes. A significant decrease in wound size could be found in both groups, treated with ointment containing and not containing fibronectin, between day 4 and 9 when wound contraction was a major contributor to wound closure. Therefore it can be concluded that topical application of fibronectin has a beneficial effect on wound healing during its early phase, but no significant influence on wound contraction.

Fibronectin, a glycoprotein, is present in plasma and extracellular matrix and is responsible for cellular adhesion. Fibronectin was purified from autologous plasma of two persistent corneal epithelial defect patients by affinity chromatogaphy and administered topically 500 micro ml, 2 dropsper time, five times a day for 3 weeks. Reepithelization began three to seven days after initiation of treatment with autologous purified fibronectin eyedrops, and epithelial defects healed nearly completely and subjective symptoms were relieved. No side effects were observed. Over a follow-up period of 4 to 23 wks, no recurrences were noted.

The erectile response is peripherally mediated by cavernous nerve that contains thoracolubar sympathetic nerve and sacral parasympathetic nerve. It is known that thoracolubar sympathetic nerve involves in detumescence and sacral parasympathetic nerve in tumescence, however there are some opinions that rhoracolubar sympathetic nerve participates in psychogenic erectile mechanism. We previously reported that by the comparison with electrostimulation-induced erection, apomor- phine-induced erection was a vascular event. The aim of our study was to determine the infraspinal neural pathway of APO-induced erection. The sham operated rats remained normal in all measured respects. All rats having undergone neurotomy ot the hypogastric nerves showed APO-induced erection except one. The only 5 rats having undergone neurotomy of the pelvic nerves showed APO-induced erection. Erections could be elicited upon cavernous or pelvic nerves stimulation in all rats having undergone neurolomy of the hypogastric nerves. Among 17 rats having undergone neurotomy of the pelvic nerve erection could be elicited upon cavernous nerves slimulation in 14 rats, however. the intracavernous pressure (47.9+/-16.5 mmHg) was lower than that found in sham-operated rats. Erectile response in these 14 rats appeared to result from stimulation of penile neurons coming from the major pelvic ganglion. In contrast to no response in sham-operated rats, stimulation of the hypogastric nerves also resulted in erections in 7 out of 17 rats. In conclusion, this present study suggests that APO-induced ereclion is primarily mediated via the sacral parasympathetic nerve system and may be mediated by the thoracolumbar sympathetic pathway following injury to the parasympathetic nerve system. Furthermore we can guess the possibility that the neural pathway of psychogenic erection is same that of AP0- induced erection.

In diabetes mellitus, thickening of basement membrane in capillaries and small vessels is a well-known finding and important in the progression of diabetic microangiopathy. We evaluated whether the plasma levels of type IV collagen and fibronectin, which are important factors of basement membrane, are related with the presence of diabetic microangiopathy. Plasma type IV collagen and fibronectin levels were measured in 40 healthy controls (Mean +/- SD, age; 50.3 +/- 5.5 yr) and 94 diabetic patients (age; 52.4 +/- 13.5 yr) with and without microvascular complications. The mean plasma levels of type IV collagen (5.3 +/- 2.9 ng/ml) and fibronectin (474.4 +/- 119.4 ug/ml) in diabetic patients were significantly higher (p < 0.01) than in healthy controls (3.7 +/- 1.3 ng/ml and 319 +/- 50.9 ug/ml). The mean plasma level of type IV collagen in diabetic patients with complications (6.6 +/- 3.7 ng/ml) was significantly higher (p < 0.01) than in those without complications (4.3 +/- 1.7 ng/ml) and became higher in more complicated patients. Furthermore, the severity of retinopathy and several indicators of nephropathy such as serum BUN, creatinine and proteinuria were closely associated with plasma type IV collagen level and a significant correlation was found between plasma type IV collagen and creatinine clearance (r = -0.31, p < 0.001). There was no significant difference in plasma fibronectin concentrations, however, between the diabetic patients with complications and those without complications.(ABSTRACT TRUNCATED AT 250 WORDS)

OBJECTIVES: To identify prevalence of dementia and it's subtypes in patients with Hansen's disease in a sanatorium of Korea. METHODS: The study employs a two-stage design for case identification. One hundred-six patients with Hansen's disease aged 65 and over participated in the study. The Korean Version of the Consortium to Establish a Registry for Alzheimer's disease (CERAD-K) assessment packet was administered to One hundred-two patients with Hansen's disease. Dementia was defined using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnostic features of dementia. RESULTS: The prevalence was 15.1% in Hansen's sanatorium. The prevalence of Alzheimer's and vascular dementia were 10.4% and 4.7%. The age-adjusted prevalence rate for dementia was 11.9%. The rate of patients with dementia was 12.73% in males and 17.65% in females. CONCLSION: The prevalence of dementia in Hansen's disease sanatorium of Korea appears to be similar with those reported in previous study. Our result suggests that Hansen's disease was unrelated to prevalence of dementia, and also that the dementia is major neuropsychiatric disease in patient with Hansen's disease.

PURPOSE: HPV (human papillomavirus) are known as the major causative agent for development of cervical cancer. High-risk HPVs, especially HPV-16 /18 DNA, are often found to be integrated into the human genome in high grade CINs as well as cervial cancer. Investigation of the relationship between the genomic states of HPV genes and their antibody response against the HPV-16 Ll/L2 virus-like particles (VLPs) and the in vitro translated E6 and E7 proteins may help to explain the mechanism of HPV-related cervical carcinogenesis and host immune responses. MATERIALS AND METHODS: Cervical cancer tissues obtained from 41 patients with cervical cancer were studied by PCR, Southern blot hybridization and the antibody response against HPV-16 Ll/L2 VLPs and HPV-16 E6, E7 proteins of serum were tested by ELISA and radioimmunoprecipitation assay (RIPA), respectively. RESULTS: Integrated forms of the HPV-16 DNA were found in 23 of the 38 patients (60.5%). The HPV-16 positive cervial cancer patients had a significantly higher prevalence (39.5%; 15/38) of antibodies to HPV-16 Ll/L2 VLPs than 8.7% (2/28) of the the control group (p<0.05). Antibodies to HPV-16 Ll/L2 VLPs were more detectable in 60% (9/15) of the cervical cancer patients with episomal forms of HPV-16 DNA than those who having only integrated HPV-16 (26.1%; 6/23) (p<0.05). Antibodies to E6 and E7 proteins were positive in 36.8% (14/38) and 50% (19/38) of the patients with HPV-16 positive cervical cancer. And those were siginificantly higher than the positivities for the control group (8.3% and 2.8%), (p<0.05). The difference between seroreactivities to E6 and E7 proteins in the patients with episomal forms of HPV-16 DNA (pure episomal and mixed forms) and those with integrated froms of HPV-16 DNA was not significant (P>0.05). CONCLUSION: Integrated forms of HPV-16 DNA were prevalent in most patients with cervical cancer. Antibodies to HPV-16 Ll/L2 VLPs, in vitro translated HPV-16 E6 and E7 proteins appeared in the significantly larger proportions of the HPV-associated cervical cancer patients than in the controls. Antibodies to HPV-16 Ll/L2 VLPs were more detectable in the cervical cancer patients with episomal form of HPV-16 DNA than those who having only integrated forms of HPV-16. Antibody responses to HPV-16 E6 and E7 proteins were not influenced by the different viral states. More numbers of studies would be necessary to determine the relationship between the genomic states of HPV and the immune responses to their proteins by the such genomic and serologic parameters.
