Recently we have experienced one case of pulmonary lymphangioleiomyomatosis(LAM). A 49 year-old woman visited the outpatient department complaining of longstanding dyspnea, which was aggravated by exercise. Although the chest PA film showed nothing more than a slight increase in interstitial marking, a lung HRCT revealed multiple cystic lesions of a similar size that were scattered through out the whole field in both lungs. An abdominal CT detected an angiomyolipoma located in the midbody of the left kidney. Video-assisted thoracic surgery(VATS) was performed for the pathologic diagnosis. On gross examination of the biopsy lung, a pulmonary LAM was confirmed by a finding of smooth muscle proliferation in the interstitum of the lung. After the final diagnosis, oral medroxyprogesterone was prescribed and she is presently in a stable condition.

A 7-year-old intact female, Miniature Schnauzer dog was presented with an acute seizure episode and tremors. Fever and panting were noted when presented. Physical examination revealed apparent forelimb muscle rigidity, fasciculations and stiff gait. Characteristic laboratory findings in this dog were severe hypocalcemia with hyperphosphatemia. The low serum concentration of intact parathyroid hormone and ionized calcium levels were consistent with the diagnosis of primary hypoparathyroidism. In addition, there were increased urinary excretion of calcium and decreased urinary excretion of phosphorus in this case. Urgent treatment was initiated with 10% calcium gluconate. The dog remained healthy with vitamin D analogue and oral calcium supplementation. A transient hyperphosphatemia was controlled well with sevelamer hydrochloride. To the author's knowledge, this is the first case report describing the clinical and laboratory characteristic features of canine primary hypoparathyroidism and its clinical outcome in Korea.

Background: Interventional pain management (IPM) is a branch of medical science that deals with management of painful medical conditions using specially equipped X-ray machines and anatomical landmarks. Interventional physiatry is a branch of physical medicine and rehabilitation that treats painful conditions through intervention in peripheral joints, the spine, and soft tissues. Methods: A cross-sectional study was conducted using three years of hospital records (2006 to 2008) from the Physical Medicine and Rehabilitation Department at Chittagong Medical College Hospital in Bangladesh, with a view toward highlighting current interventional pain practice in a tertiary medical college hospital. Result: The maximum amount of intervention was done in degenerative peripheral joint disorders (600, 46.0%), followed by inflammatory joint diseases (300, 23.0%), soft tissue rheumatism (300, 23.0%), and radicular or referred lower back conditions (100, 8.0%). Of the peripheral joints, the knee was the most common site of intervention. Motor stimulation-guided intralesional injection of methylprednisolone into the piriformis muscle was given in 10 cases of piriformis syndrome refractory to both oral medications and therapeutic exercises. Soft tissue rheumatism of unknown etiology was most common in the form of adhesive capsulitis (90, 64.3%), and is discussed separately. Epidural steroid injection was practiced for various causes of lumbar radiculopathy, with the exception of infective discitis. Conclusion: All procedures were performed using anatomical landmarks, as there were no facilities for the C-arm/diagnostic ultrasound required for accurate and safe intervention. A dedicated IPM setup should be a requirement in all PMR departments, to provide better pain management and to reduce the burden on other specialties.

Stimulation of AMP-activated protein kinase (AMPK) signaling followed by increase of glucose uptake in L6 myotubes were studied with organic solvent extract of Malva verticillata (MV) seeds. Ethanol extract of M. verticillata seeds (MVE) significantly increased the phosphorylation level of AMPK, acetyl-CoA carboxylase (ACC), and glucose uptake in L6 myotube cells. The MVE was fractionated with n-hexane (MVE-H), chloroform (MVE-C), ethylacetate (MVE-E), n-butanol (MVE-B), and water (MVE-W). MVE-H (150 ${\mu}g$/ml) showed the highest phosphorylating activity and increased glucose uptake by 2.3-fold. Oral administration of MVE-H (40 mg/kg) for 4 weeks to type 2 diabetic (db/db) mice reduced non-fasting and fasting blood glucose levels by 17.1% and 23.3%, respectively. Phosphorylation levels of AMPK and ACC in the soleus muscle and liver tissue of db/db mice were significantly increased by the administration of MVE-H. MVE-H was further fractionated using preparative HPLC to identify the AMPK-activating compounds. The NMR and GC-MS analyses revealed that ${\beta}$-sitosterol was a major effective compound in MVE-H. Phosphorylation levels of AMPK and ACC, and glucose uptake were significantly increased by the treatment of MVE-S (${\beta}$-sitosterol) isolated from M. verticillata to L6 cells, and these effects were attenuated by an AMPK inhibitor (Compound C) pretreatment. These results, taken together, demonstrate that increased glucose uptake in L6 myotubes by MVE-H treatment is mainly accomplished through the activation of AMPK. Our finding suggests that the extract isolated from M. verticillata seed would be beneficial for the treatment of metabolic disease including type 2 diabetes and hyperlipidemia.

The purpose of this study was to determine whether there was any correlation between temporomandibular joint dysfunction and structure of the mandibular condyle. Weanling rats had their masseter muscles resected and immunohistochemical findings were observed with a light microscope. The results obtained were as follows : 1. The condylar cartilage region was divided into articular, proliferating, cartilage cell and hypertrophic cell layers according to cell morphology. 2. In light microscopic views, the proliferating and cartilage cell layers of the experimental group decreased gradually and at the 8th week significantly. 3. In immunohistochemical staining for type I and II collagen, a reaction was detected in the lower part of proliferating cell and cartilage cell layers. In the cartilage cell layers, a stronger cellular reaction was present. Immunohistochemical staining for type II collagen reacted more strongly than that of type I collagen. 4. In immunohistochemical staining for proteoglycan, the staining of the experimental group resembled the control group and gradually showed a weak reaction. The proliferating and cartilage cell layers reacted more strongly than the hypertrophic cell layer. 5. In immunohistochemical staining for proliferating cell nuclear antigen(PCNA), the strong reaction was detected in the nucleus of the proliferating cell layer both in control and experimental groups. But the thickness of the proliferating layer decreased in experimental group, consequently the reaction of the experimental group was reduced more than that of the control group.

The purpose of this study was to investigate the effect of electrical anesthesia induced by non-acupuncture point stimulation on inhibition of amplitude of digastric EMG evoked by noxious electrical stimuli in teeth and gingiva. Experiments were performed with dogs anesthetized with intraperitoneal pentobarbital sodium in an initial dose of 30mg/kg. Maintenance doses of 4.0ml/hour were given through a cannula in the femoral vein using a constant infusion pump. Anterior belly of digastric muscle was exposed and a pair of 0.1mm wire electrodes were inserted for E.M.G. recording. Bipolar electrodes were inserted into the labial and lingual surface of upper canine and the labial area of upper gingiva. Noxious stimuli were delivered to the tooth and gingiva through those electrodes by electric stimulator. Non-acupuncture point stimulation of 2Hz was delivered bilaterally to the femoral area. Amplitudes of digastric E.M.G. were measured from the oscilloscope and the monitor connected to amplifier at different intensities of electronic anesthesia of 1 volt, 4 volt and 10 volt. The inhibited rate of the amplitudes of digastric E.M.G. were analysed statistically with paired t-test. The following results were obtained : 1. Non-acupuncture point stimulation with intensities of 1 volt, 4 volt and 10 volt showed the inhibitory effect on pain of 15%, 25% and 16% in teeth and 15%, 18% and 12% in gingiva respectively 2. In tooth, statistical significance was observed between control and each group. In gingiva, there was statistical significance between control and group 1, 2 except group 3 From these results, low frequency electrical stimulation of non-acupuncture point resulted in reducing of dental and gingival pain, it could be used as adjunct to other pain control methods.

We designed to investigate the relationship the cold-hot theory of herbology and body temperature in experimental model. we prepared four kinds of oriental medicine, which consisted of two cold herbs, Daehwang and Seokgo, and two hot herbs, Buja and Padu. Decrease of body temperature by cold exposure for 12 hour was not inhibited by four herbs oral administration for two weeks. Thermogenesis in mammals is an essential physiological function to maintain the body temperature. Mitochondrial uncoupling proteins(UCPs), which have a potential to generate heat by uncoupling oxidative phosphorylation, apper to play a crucial role in thermogenesis. Therefore UCP is commonly recognized as a key molecule in metabolic thermogenesis and its dysfunction contributes to the development of obesity. In these experiments, Daehwang water extracts inhibited the UCP1 mRNA expression increase by cold exposure in brown adipose tissue. But other herbs did not significantly influence on UCPs mRNA expression in white adipose tissue and seleus muscle tissue. Based on this experiment, we will try to clarify the effects of Daehwang water extracts on UCP1 expression and function.

Bisphenol-A(BPA) is a member of alkylphenol family, and shows adverse effects including reduced fertility, reproductive tract abnormalities, metabolic disorder, cancer induction, neurotoxicity and immunotoxicity. In the present study, we conducted Hershberger assay to evaluate whether the two candidates to replace BPA have androgenic or antiandrogenic activity. The assay was carried out using immature castrated Sprague-Dawley male rats. After 7 days of the surgery, testosterone propionate (TP, 0.4 mg/kg/day) and test materials (low dose, 40 mg/kg/day; high dose, 400 mg/kg/day) were administered for 10 consecutive days by subcutaneous (s.c.) injection and oral gavage, respectively. Test materials were BPA, isosorbide (ISO) and cyclohexanedimethanol (CHDM). The rats were necropsied, and then the weights of five androgen-dependent tissues [ventral prostate, seminal vesicle, levator ani-bulbocavernosus (LABC) muscle, paired Cowper's glands, and glans penis] and three androgen-insensitive tissues (kidney, spleen and liver) were measured. All test materials including BPA did not exhibit any androgenic activity in the assay. On the contrary, antiandrogen-like activities were found in all test groups, and the order of the intensity was CHDM > BPA > ISO in the five androgen-sensitive tissues. There was no statistical difference between low dose treatment and high dose treatment of BPA group as well as ISO group. In CHDM group, high dose treatment exhibited most severe weight reduction in all measured tissues. There was no statistical difference in androgen-insensitive tissue measurements, except BPA groups. Since the effects of ISO treatment on the accessory sex organs were much less or not present at all when compared to those of BPA, ISO could be a strong candidate to replace BPA. CHDM treatment brought most severe weight reduction in all of androgen-sensitive tissues, so this material should be excluded for further screening of BPA substitute selection.

In the present study, we employed Hershberger assay to determine possible androgenic or antiandrogenic activities of three di-2-ethylhexyl phthalate (DEHP) substitute candidates. The assay was carried out using immature castrated Sprague-Dawley male rats. After 7 days of the surgery, testosterone propionate (TP, 0.4 mg/kg/day) and test materials (low dose, 40 mg/kg/day; high dose, 400 mg/kg/day) were administered for 10 consecutive days by subcutaneous (s.c.) injection and oral gavage, respectively. Test materials were DEHP, 2-ethylhexyl oleate (IOO), 2-ethylhexyl stearate (IOS) and triethyl 2-acetylcitrate (ATEC). The rats were necropsied, and then the weights of five androgen-dependent tissues [ventral prostate, seminal vesicle, coagulating glands, levator ani-bulbocavernosus (LABC) muscle, paired Cowper's glands, and glans penis] and four androgen-insensitive tissues (kidney, adrenal glands, spleen and liver) were measured. All test materials including DEHP did not exhibit any androgenic activity in the assay. On the contrary, antiandrogen-like activities were found in all test groups, and the order of the intensity was ATEC < DEHP < ISO < IOO in the five androgen-sensitive tissues. There was no statistical difference between low dose treatment and high dose treatment of all replacement candidate groups. In DEHP groups, high dose treatment exhibited significant weight gains in LABC and Glan Penis. There was no statistical difference in androgen-insensitive tissue measurements. Since the effects of ATEC treatment on the accessory sex organs were much less or not present at all when compared to those of DEHP, ATEC could be a strong candidate to replace DEHP. IOO treatment brought most severe weight reduction in all of androgen-sensitive tissues, so this material should be excluded for further screening of DEHP substitute selection.

Objective: This study investigated the effects of air stacking training (AST) on pulmonary function, respiratory strength, and peak cough flow (PCF) in persons with cervical spinal cord injury (CSCI). Design: Randomized controlled trial. Methods: A total of 24 persons with CSCI were randomly allocated to the AST group (n=12) or the incentive spirometry training (IST) group (n=12). Patients with CSCI received AST or IST for 15 minutes, with 3 sessions per week for 4 weeks, and all groups performed basic exercises for 15 minutes. In the AST group, after the subject inhaled the maximal amount of air as best as possible, the therapist insufflated additional air into the patient's lung using an oral nasal mask about 2-3 times. In the IST group, patients were allowed to hold for three seconds at the maximum inspiration and then to breathe. The pre and post-tests measured forced vital capacity (FVC), forced expiratory volume one at second (FEV1), maximal expiratory pressure (MEP), maximal inspiratory pressure (MIP) and PCF. Results: Both groups showed significant improvements in FVC, FEV1, MEP, MIP and PCF values after training (p<0.05). The FVC in the post-test and the mean change of FVC, FEV1, MIP were significantly higher in the AST group than the IST group (p<0.05). Conclusions: The findings of this study suggested that AST significantly improved pulmonary function, respiratory strength, and PCF in persons with CSCI. Therefore, AST should be included in respiratory rehabilitation programs to improve coughing ability, pulmonary function and respiratory muscle strength.
