Extradural lipomas have been frequently reported in the literature, but intramedullary lipomas are far rarer, constituting only approximately 2% of total intramedullary tumors. Intramedullary lipomas are also commonly associated with spinal dysraphism. Lipomas which are not associated with spinal dysraphism are present in only about 1% of spinal lipoma patients. Here, we report a rare case of a patient suffering from an isolated intramedullary lipoma without evidence of spinal dysraphism.

Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Here, we present a case of chest wall MFH along with a schwannoma mimicking distant metastasis in the right upper arm. The patient was treated by radical en bloc resection and survived for more than 9 years without recurrence.

We study the compatibility conditions and the existence of solutions or overdetermined PDE systems that admit complete prolongation. For a complete system of order k there exists a submanifold of the ($\kappa$-1)st jet space of unknown functions that is the largest possible set on which the initial conditions of ($\kappa$-1)st order may take values. There exists a unique solution for any initial condition that belongs to this set if and only if the complete system satisfies the compatibility conditions on the initial data set. We prove by applying the Frobenius theorem to a Pfaffian differential system associated with the complete prolongation.

Mussel, Mytilus galloprovincialis, was transplanted reciprocally between contaminated site (St. STP) and relatively less contaminated site (St. UB) in Onsan Bay, Korea in order to estimate heavy metal accumulation and release. Transplanted and indigenous mussels were collected 8 times over 108 days deployment at both sites and analyzed for Cd, Cu, Pb and Zn using ICP/MS. Cu and Zn concentration did not show any significant differences between transplanted and indigenous mussels throughout the experiment period, although dissolved Cu and Zn concentrations in seawater were significantly higher at contaminated site. Pb accumulated rapidly, while Cd did not show any accumulation in the mussels transplanted from St. UB to St. STP. These accumulation patterns might reflect the variation of dissolved metal concentration; dissolved Pb concentration was significantly higher in St. STP than St. UB, while dissolved Cd concentration was similar between both sites throughout this experiment. Release of Cd and Pb in the mussels transplanted from St. STP to St. UB was not significant during the transplantation period. The levels and variation of Pb and Cd concentrations in mussels transplanted from St. STP to St. UB were similar to those in the indigenous mussels at St. STP throughout the period. Therefore, Cd and Pb accumulated in indigenous mussels may indicate the integrated metals throughout their lives, not responding to the present status of seawater because the release of accumulated metals in mussels occurs very slowly when the seawater metal levels are lowered. On the other hand, since the transplanted mussels can respond immediately to the levels of metals in seawater, it may be suggested that the present status of heavy metals in seawater can be only acquired from the metal levels of mussels transplanted from clean environments.

Objective: Recently. many studies have showed the evidences of the effect of the Electro-acupuncture treatment through scientific. Methods : One of these methods is functional MRI. We performed electro-acupuncture on Zusanli(St36) and observed the change of brain activation using fMRI. Zusanli(St36) is located on the lateral side of the lower leg. 3 cun(寸) inferior to the Patella of the lower border. Theoretically and clinically. this point has been considered very important for gynecological disorders. spleen and stomach disorders. and psychological disorders. To see the effects of electro-acupuncture stimulation on Zusanli(St36). the experiment was carried out on twelve healthy volunteers. using the gradient echo sequence with the 3.0T whole-body fMRI system(ISOL). After the needle insertion on right Zusanli(St36). 2 Hz of electric stimulation was given for 30 seconds. repeated five times. with 30 seconds' intervals. The Image analysis including motion correction. talairach transformation, and smoothing was done with SPM99. Results ad conclusion : The electro-acupuncture stimulation on Zusanli(St36) activates Brodmann Area 6, 13, 2, 19, 21, 22, 39, 40, 38, 3which indicates the pathways of the electro-acupuncture stimulation on Zusanli(St36) and the possibility of the relationship of the electro-acupuncture stimulation on Zusanli(St36) with autonomic nervous system, internal organic system.

Objective : This research carried out to find out the effective efficiency of acupuncture at ST36 GB39 and herbal-acupuncture using different concentrational Uris Fel Bovis Calculus on adjuvant arthritis in rats. Method : In this study, I do acupuncture treatment and herbal-acupuncture in ST36 GB39 by solution that diluted to fivefold and tenfold with combined solution of Bovis Calcuclus and Ursi Fel at 10:1. And then I observed the change of inhibitory rate of paw edema, body weight, hematologic assay, histologic assay. Result : 1. In Adjuvant Arthritis in rats, the herbal-acupuncture group 1 is more efficienct then acupuncture group. 2. In histologic assay of knee joint, synovial cell and fibroblast markedly activated in herbal-acupuncture group. 3. The albumin level in serum more markedly increased in herbal-acupuncture group 2 than the control group. 4. The paw edema significantly decreased in acupuncture group and herbal-acupuncture group 2 compared with the control group. 5. The body weight significantly increased in acupuncture group and herbal-acupuncture group 2 compared with the control group. Conclusion : In these results, The herbal-acupuncture using Ursi Fel, Bovis Calculus, suppress inflammation of Adjuvant Arthritis, and decrease markedly the count of WBC, and increase the albumin level in serum, and have an influence on Adjuvant Arthritis with activating of synovial cell, fibroblast. And these were more effective than the others, and then needed consistent study of its mechanism.

Background: Workers in logistics centers are always pressed for time to collect and pack products. They also participate in high-intensity manual labor in which various musculoskeletal hazards exist. In the case of logistic center labor, it is estimated that there is a high risk of presenteeism due to the above characteristics which can cause deterioration of workers' mental health. However, there is insufficient research on this topic. Methods: Workers in a logistic center were surveyed using an Internet questionnaire. The survey items included demographic characteristics, labor intensity and work-related factors, and mental health aspects such as depression and anxiety. The survey was conducted for about a month from July 26, 2021 and a total of 353 people were analyzed. Through the χ² test and t-test, the characteristics of workers who experienced presenteeism were examined and the prevalence ratios (PRs) of depression and anxiety experiences were calculated by multivariable Poisson regression. Afterwards, stratification analysis considering gender, the type of contract, and labor intensity was implemented. Results: In the group that experienced presenteeism, the number of working days per week was higher and fixed-term workers, high labor intensity, and sleep deprivation were more common. In the multi-Poisson regression analysis conducted by adjusting the demographic characteristics, working hours, and work-related factors, the PRs of depression and anxiety were 1.98 (95% confidence interval: 1.24-3.18) and 1.81 (1.22-2.68), respectively. In particular, the p-value for interactions was significant when stratified with the type of contract. Conclusions: As a result of the study, presenteeism and mental health were associated in logistic center workers. To prevent mental health issues of logistic center workers, management of presenteeism is necessary and a prospective study is needed.
