Many disorders in neuropsychiatric field demonstrate variable motor disturbances as their clinical feature or in their courses of illness and also due to psychopharmacological treatment. Although association of such motor disturbances with the pathophysiological aspect of various neuropsychiatric illness are still lacking, some form of motor disturbance offer a window though which pathophysiologic mechanism of such illness can be viewed. Cognitive control of motor functions are briefly reviewed in this article and the importance and method of motor function assessment in major neuropsychiatric disorders are also discussed. Motor dysfunction of major neuropsychiatric illness such as schizophrenia and mood disorders may offer a chance of a deeper understanding on the pathophysiologic aspect of their clinical presentation.

The current understanding of the neurobioloby of anxiety is generally based on experimental animal model, empirical effective psychopharmacological agents, chemical and naturalistic challenge paradigms, and psychoendocinological assessment. This article focuses on reviewing neuroanantomical, neuroendocinological and neurofunctional research of anxiety disorder. In the decade ahead, we anticipate that extension of current research and the new integrated approach promise novel insight into mechanism of anxiety.

Journal of the Korean Society of Biological Psychiatry 2001;8(1):20-36
The debate about whether depressive disorders should be divided into categories or arrayed along a continuum has gone for decade, without resolution. In our review, there is more evidence consistent with the spectrum concept than there is with the idea that depressive disorders constitute discrete clusters marked by relatively discontinuous boundaries. First, "depression spectrum", "is there a common genetic factors in bipolar and unipolar affective disorder", "threshold model of depression" and "bipolar spectrum disorder" are reviewed. And, a new subtype of depression is so called SeCA depression that is a stressor-precipitated, cortisol-induced, serotonin-related, anxiety/aggression-driven depression. SeCA depression is discussed. But, there is with the idea that depressive disorders constitute discrete subtypes marked by relatively discontinuous boundaries. This subtypes of depressive disorder were reviewed from a variety of theoretical frames of reference. The following issues are discussed ; Dexamethasone suppression test(DST), TRH stimulation test, MHPG, Temperament Character Inventory(TCI), and heart rate variability(HRV).

Henoch-Schonlein purpura is a common pediatric disease presenting most frequently with skin, gastrointestinal, joint and renal manifestations. But in cases are infrequently only severe gastrointestinal manifestations. It is hard to diagnose promptly and exactly. Clinical manifestations and laboratory findings were observed and analyzed in 20 cases with Henoch-Schonlein purpura which were considered as acute abdomen, hospitalized at Kyung Hee university Hospital during the period from December, 1982 to September, 1992. The following results were obtained; 1) The age distribution of Henoch-Schonlein purpura had a peak incidence between 7 to 9 year old. And male preponderance was observed with male to female ratio of 2.33 to 1. 2) The most prevalent season for the initial presentation of Henoch-Schonlein purpura was in fall: in 10 cases (50%). 3) The frequency of each type of clinical manifestations showed 20 (100%), 20 (100%), 18 (90%), 8(40%) cases for skin, gastrointestinal, joint and renal manifestation respectively in order of frequency. 4) The common previous illness were URI, 40 cases (50%) and allergy, 2 cases (10%). 5) The onset time of skin manifestation from admission were 1 to 4 days (75%0, 5 to 8 days (15%), 9 to 12 days (10%) explolaparotomies were done the last 2 cases. 6) In all cases, X-ray study (100%), abdominal sono (50%), Meckels scan and colon study (5%) respectively were done. 7) Hematologically leukocytosis over 10,000/mm3 was observed in 80% of cases and increase in ESR over 20 mm/hr in 65% of cases. Coagulation studies, immunologic and complement level revealed the result within normal range in most of the cases. 8) Among 8 cases with renal involvement, all cases had both hematuria and proteinuria. 9) Most cases were recovered within 4 weeks but in 4 cases, renal biopsies were done because of relapse. The results were Meadow classification grade I (1 case), II (1 case), IVa (2 cases). After renal biopsy, steroid pulse therapy was started.

BACKGROUND: Interferon alpha-2a has already been shown to be effective in clinical use of virus-originated diseases such as hairy cell leukemia, condyloma acuminatum, and AIDS-related Kaposi's sarcoma. The use of recombinant alpha-interferon may allow common warts to be treated relatively atraumatically and with less incidence of recurrence. OBJECTIVE: We tried to determine the safety and effectiveness of intralesional injections of recombinant alpha-2a interferon in the treatment of patients with common warts. METHODS: A single wart on each patient was weekly injected with 0.75 to 1.5×10(5) IU/25mm2 of interferon for 8 weeks, and the response to treatment was followed up-to 6 months. RESULTS: Clearing of the treated wart at the end of treatment occurred in 5(71%) out of 7 patients and the rest showed no improvement. With evaluation for relapses up-to 6 months after treatment, warts relapsed in 2(40%) out of 5 patients. Therefore, 3(43%) out of 7 patients were completely free of warts 6 months after treatment. CONCLUSION: Intralesional recombinant interferon alpha-2a has a limited therapeutic effect, but may be considered as a therapeutic modality of recalcitrant verruca or when it can be anticipated that destructive techniques or blistering agents will not be tolerated.

BACKGROUND: Superoxide dismutases (SOD) are important metallo-enzymes which scavenge and dismutase the superoxide free radical. They are thought to be the main enzymes in the antioxidant defense system. In the several cell ines the induction of Mn-SOD expression by tumor necrosis factor (TNF)-alpha which is a known inflammatory cytokine, suggests that Mn-SOD may play a role in the inflammatory process. However, this effect is occurred. OBJECTIVE: The present study was undertakento determine whether the induction of SOD expression by TNF-alpha, in the keratinocytes is occurred. METHODS: Primary keratinocyte cultures from neonatal foreskins were grown in complete MCDB 153 medium. Measurement of superoxide radical and SOD activity were performed according to Babior and Fridovich methods, respectively. RESULTS: 1. The release of superoxide radical were measured after 30, 60, 90 minutes exposure to 10ng/ms TNF-alpha, THE RESULTS SHOWS 2.94+/-0.30 NMOL/2x105, 3.55+/-0.52 NMOL/2x105, 4.13+/-0.70 nmol/2x105 respectivelyl The increase of superoxide radical release was detectable in a time dependent manner. 2. Total SOD activity without treatment of TNF-alpha at 24 hours was 18.46+/-2.85, Total SOD activities after treatment of 1, 10, 100 ng/ml TNF-alpha at 24hours were 36.47+/-6.80, 88.01+/-7.79, 94.50+/-8.97 respectively, which suggested that TNF-alpha induced increase of total SOD significantly (p<0.050. TNF-alpha stimulate total SOD induction in a dose and time dependent manner, although the effects were not outstanding. Mn-SOD activity after treatment of 100 ng/ml TNF-alpha at 48 hours was 84.12+/-14.83, which was approxdimately 10.5 fold of that of the untredated case. TNF-alpha also induced the Cu, Zn-SOD activity, but the effect was not so much as in the case of Mn -SOD. CONCLUSION: TNF-alpha induces production of total SODD activities, especially Mn-SOD in the human kerati ocytes, which may be to protect cells from inflammation mediated oxidative damage, namely production of total SOD protein, especially Mn-SOD in response to TNF-alpha induced and scavenged overproduced superoxide radical which in turn may result in protection of the keratinocytes.

Clinics in Shoulder and Elbow 2014;17(4):152-158
BACKGROUND: To investigate the effectiveness of reverse total shoulder arthroplasty (RTSA) in treating irreparable massive rotator cuff tears (RCTs). METHODS: Twenty-nine patients who underwent RTSA for the treatment of irreparable massive RCTs and completed follow-up for at least 1 year were selected. Their mean age was 69.7 years (range, 59-80 years). The mean follow-up was 17.7 months (range, 12-42 months). The shoulder range of motion was measured preoperatively and at final follow-up. The functional result was evaluated using visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeon (ASES) score, and Korean Shoulder Society (KSS) score. Additionally, the shoulders were categorized into two groups depending on prior history of surgery and the clinical outcomes were analyzed between two groups. RESULTS: Mean pain VAS improved, from 6.6+/-1.2 to 2.7+/-0.9 (p=0.001), and the mean functional VAS from 35.7+/-4.2 to 73.3+/-5.4 (p=0.006). The mean ASES score improved from 37.2+/-2.8 to 75.0+/-3.8 (p=0.012). The mean KSS improved from 36.5+/-7.2 to 75.6+/-5.4 (p=0.009), the mean forward elevation from 66.3+/-4.7 to 135.6+/-8.4 (p=0.0001), and the mean abduction from 45.2+/-4.2 to 119.0+/-6.5o (p=0.0001). Internal rotation differed significantly from the first sacral to the third lumbar vertebrae (p=0.036). External rotation did not change significantly (p=0.076). There was also no statistically significant difference between groups (no previous operation versus none). Four complications occurred: one superficial infection, one with anterior dislocation, one acromial fracture, and one clavicle fracture. CONCLUSIONS: RTSA provides reliable pain relief and recovery of shoulder function in patients with massive irreparable RCTs in short-term follow-up.
