Facial palsy is a common disease in clinic, which can be classified into central and peripheral according to the causes. The central facial palsy is caused by cerebral vascular accident, brain tumor, etc. The peripheral facial palsy comes from cold stimulus on face, regional infection of virus, suppurative tympanitis, inflammation on mastoid process, pathological teeth, trauma like cranial fracture, and so forth, They have distinctive features in diagnosis. While the central facial palsy is followed by hemiplegia and articulation disorder, the peripheral one by the disappearance of wrinkles on the forehead and rising of eyeball on paralyzed side when closing the eyes. Most of the cases in this thesis are peripheral palsy. The social classes and ages of the patients are so various that the treatments must be applied from various standpoints. The statistical data shows that the functional weakness of the whole body is the fundamental condition of the facial palsy. Therefore it is very important to find and the exact pathology and treatment appropriate for Hyungsang of the patients.

The aim of this study was to investigate whether matrix metalloproteinase (MMP) inhibitors attenuate neuroinflammation in an ischemic brain following photothrombotic cortical ischemia in mice. Male C57BL/6 mice were anesthetized, and Rose Bengal was systemically administered. Permanent focal ischemia was induced in the medial frontal and somatosensory cortices by irradiating the skull with cold white light. MMP inhibitors, such as doxycycline, minocycline, and batimastat, significantly reduced the cerebral infarct size, and the expressions of monocyte chemotactic protein-1 (MCP-1), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and indoleamine 2,3-dioxygenase (IDO). However, they had no effect on the expressions of heme oxygenase-1 and neuroglobin in the ischemic cortex. These results suggest that MMP inhibitors attenuate ischemic brain injury by decreasing the expression levels of MCP-1, TNF-${\alpha}$, and IDO, thereby providing a therapeutic benefit against cerebral ischemia.

Dansam, the root of Salvia miltiorrhiza Bge, (Labiatae), has a bitter taste and a slightly 'cold' property, and is nontoxic. In the present study, effect of Dansam on nitric oxide (NO) generation from peritoneal macrophags was examined. Dansam had no effect on NO generation by itself, whereas recombinant interferon-${\gamma}\;(rIFN-{\gamma})$ alone had modest activity. When Dansam was used in combination with $rIFN-{\gamma}$, there was a marked cooperative induction of NO generation in a dose-dependent manner, The optimal effect of Dansam on NO generation was shown at 6 hr after treatment with $rIFN-{\gamma}$. Furthermore, the effect of Dansam was mainly dependent on Dansam-induced tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$ secretion. These results suggest that Dansam induces NO generation from macrophages by the result of Dansam-induced $TNF-{\alpha}$ secretion.

Angioleiomyoma is an infrequent benign smooth muscle tumor that arises from smooth muscle cells of arterial or venous walls in the tunica media layer. It would be found in the dermis, the subcutaneous tissue, or the superficial fascia of the anywhere in the body and is most often seen in the lower extremities. The typical lesion is a small, slowly growing, round, but firm and mobile nodule. We report a case of angioleiomyoma located on the anterior aspect of the elbow, which was mistaken for extradigital glomus tumor after history taking, physical examination. With point tenderness and worsening sharp pain in cold exposure for several years, the patient was referred for a further evaluation, and the lesion was 5 mm sized well-circumscribed mass in the anterior elbow with vascular signals on color and power Doppler by ultrasonography and finally diagnosed as angioleiomyoma following complete excision and histological evaluation.

Background: Spinal nerve ligation (SNL) injury in rats produces a pain syndrome that includes mechanical and thermal allodynia. Previous studies have indicated that proinflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) play an important role in peripheral mediation of neuropathic pain, and that altered dorsal root ganglion (DRG) function and degree of DRG neuronal apoptosis are associated with spinal nerve injury. The present study was conducted to evaluate the expression of TNF-${\alpha}$ and the extent of apoptosis in the dorsal root ganglion after SNL in rats. Methods: Sprague-Dawley rats were subjected to SNL of the left L5 and L6 spinal nerves distal to the DRG and proximal to the formation of the sciatic nerve. At postoperative day 8, TNF-${\alpha}$ protein levels in the L5.6 DRG were compared between SNL and naive groups using ELISA. In addition, we compared the percentage of neurons injured in the DRG using immunostaining for apoptosis and localization of activated caspase-3. Results: SNL injury produced significant mechanical and cold allodynia throughout the 7-day experimental period. TNF-${\alpha}$ protein levels were increased in the DRG in rats that had undergone SNL ($12.7{\pm}3.2$ pg/100 ${\mu}g$, P < 0.001) when compared with naive rats ($4.1{\pm}1.4$ pg/100 ${\mu}g$). The percentage of neurons or satellite cells co-localized with activated caspase-3 were also significantly higher in rats with SNL than in naive rats (P < 0.001, P < 0.05, respectively). Conclusions: SNL injury produces mechanical and cold allodynia, as well as TNF-${\alpha}$ elevation and apoptosis in the DRG.

Background: Hypothermia is a crucial environmental factor that elevates the risk of cardiovascular disease, but the underlying effect is unclear. Objectives: This study examined the role of cold stress (CS) in cardiac injury and its underlying mechanisms. Methods: In this study, a chronic CS-induced myocardial injury model was used; mice were subjected to chronic CS (4℃) for three hours per day for three weeks. Results: CS could result in myocardial injury by inducing the levels of heat shock proteins 70 (HSP70), enhancing the generation of creatine phosphokinase-isoenzyme (CKMB) and malondialdehyde (MDA), increasing the contents of tumor necrosis factor-α (TNF-α), high mobility group box 1 (HMGB1) interleukin1b (IL-1β), IL-18, IL-6, and triggering the depletion of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH). Multiple signaling pathways were activated by cold exposure, including pyroptosis-associated NOD-like receptor 3 (NLRP3)-regulated caspase-1-dependent/Gasdermin D (GSDMD), inflammation-related toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)-mediated nuclear factor kappa B (NF-κB), and mitogen-activated protein kinase (MAPK), as well as oxidative stressinvolved thioredoxin-1/thioredoxin-interacting protein (Txnip) signaling pathways, which play a pivotal role in myocardial injury resulting from hypothermia. Conclusions: These findings provide new insights into the increased risk of cardiovascular disease at extremely low temperatures.

Purpose: We reviewed 66 cases of the glomus tumors in the hands. The purpose of this study was to review the characteristic signs and symptoms of glomus tumors and the surgical outcomes. We made hypothesis that (1) our guideline for surgical excision are reliable and (2) our surgical technique is efficient and less harmful to the nail root. Materials and Methods: The clinical diagnosis was made with occasional radiological studies and surgical excision was performed according to our indications. Patients with electrical shock-like pain by touching (the essential symptom) and at least 2 of 4 clinical signs and symptoms (cold hypersensitivity, paroxysmal pain that radiated proximally, blue discoloration, nail deformity for dorsal tumor or a palpable nodule for pulp tumor) underwent surgical excision. Results: The duration of symptoms of the patients was about 5.3 years. No difference of prevalence was found in both hands, but the thumb and the middle finger were more affected than the other fingers. The mean follow up period was 2.4 years and none of the patients complained the same characteristic pain at the last visit. Conclusion: To the best of our knowledge, this report is the largest case series about glomus tumors in the finger tip. The clinical signs and symptoms are important to make a diagnosis of glomus tumors, and surgical excision is the treatment of choice.

A colostral protein that augments natural killer (NK) cell activity was isolated from bovine colostrum. This protein, designated matemal immunity enhancing factor (MIEF), increased NK cell-mediated cytotxicity against human tumor targets wheb added to cultures of resting peripheral blood lymphocytes. The NK cell stimulatory activity of the MIEF was demonstrated at the concentrations as low as 0.1-0.01 $\mu$g/ml. Purified MIEF showed an apparent molecular weight of 22,000 in SDS-polyacrylamide gel electrophoresis. The unusual biochemical characteristics of the MIEF distinguish it from other cytokines. The MIEF was soluble at a cold tgemperature, and precipitated by raising the temperature. This themal precipitability was reversible, and dependent on the concentration, pH and ionic strength. Maximal precipitation was observed at neutral pH, and higher ionic strength.
