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.

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.

Focal nodular hyperplasia is a benign hepatic tumor mainly composed of nodules of hepatocytes and Kupffer cells separated by fibrous septa. In general, it is difficult to differentiate focal nodular hyperplasia and hepatocellular carcinoma on ultrasonography, conventional CT(computerized tomography), and angiography. But IV bolus CT is of particular value in the diagnosis of focal nodular hyperplasia because it can divide enhanced CT into early and late phase and can characterize tumor vascularity and analyze any intratumoral elements. In our case, it was seen as a hypoechoic mass lesion on ultrasonograpl'hy and hyperdense mass lesion on early-phase IV bolus CF and isodense mass, lesion on late-phase IV bolus CT. On angiography, hypertrophy of the feeding artery and tumor staining were well visualized. The patient underwent operation and the mass was pathologically confirmed to a focal nodular hyperplasia. We report the first case of focal nodular hyperplasia on IV bolus CT in Korea.

BACKGROUND: The large surfaces of the skin are often initial site of contact between microorganism and human. The skin are coated with epidermis and epithelial cells can recognize microorganism and mount a fast defense through the production of various inducible antibiotic peptides. This leads to chracteristic broad spectrum of antimicrobial activity against bacteria, fungi, and viruses. Recent studies introduce us new peptides with antimicrobial activity such as P,-defensins and cathelicidins. They are expressed on the epithelia and polymorphonuclear leukocytes, which are first lines of defence from various invasive environments. Futhermore, they are considered very interesting and important endogenous antibiotics. Our previous study has shown that the expression of human defensin(hBD-2) mRNA, which is potent antibiotic peptide against Gram-negative bacteria(P. aeruginosa), was upregulated with ultraviolet(UV) irradiation, tumor necrosis factor-α(TNF-α) and lipopolysaccharide(LPS) in HaCaT cells. A novel hBD-3, 5-kDa, nonhemolytic antimicrobial peptide, was demonstrated a salt-insensitive broad spectrum of potent antimicrobial activity against many potentially pathogenic microbes in especially, multiresistant S. aureus. We have analyzed the expression patterns of hBD-3 in HaCaT cell lines. OBJECTIVE: This research have done in order to evaluate the expression and regulation of hBD-3 mRNA in human keratinocyte cell lines. METHODS: HaCaT cell lines were used to all culture experiments. Cultured human keratinocytes were stimulated with UV irradiation or TNF-α or LPS to determine whether hBD-3 mRNA production occurred. Reverse transcription-polymerase chain reaction (RT-PCR) was per-formed to amplify hBD-3 cDNA from stimulated keratinocytes in a time dependant manner, and densitometry was used to verify the specificity of RT-PCR amplication products. RESULTS: Expression of hBD-3 was upregulated with UV irradiation, TNF-α and LPS in Ha-CaT cells compared to control CONCLUSIONS: Human keratinocytes are capable to induce hBD-3 mRNA, as well as hBD-2, in response to UV irradiation, TNF-α and LPS. suggesting that these cells could play an important role against the bacterial infection and UV light damage in human skin.

Effect and side effects of adding 0.2% brimonidine to beta blockers was studied in 44 eyes of 32 glaucoma patients with inadequately controlled intraocular pressure[IOP]with beta blockers alone. Routine eye examination and IOP measurement were performed before the additive therapy. 0.2% brimonidine eye drops were topically applied three times a day with previously used beta blockers. IOP was measured at 1 week, 1 month, and 3months after the combined therapy. Mean IOP was 17.2 +/-1.8 millimeters of mercury before combined therapy ;13.5 +/-1.6 millimeters of mercury after 1 week, 14.3 +/-2.5 millimeters of mercury after 1 month and 13.6 +/-2.3 millimeters of mercury after 3 months of therapy. Side effects of combined therapy were oral dryness[25.0%], ocular pain[9.4%], and blurring[6.3%]. These results indicate that adding 0.2%brimonidine in patients treated with beta blockers causes a further reduction of IOP that may prove to be clinically useful in glaucoma therapy.

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.
