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.

Liquid crystal thermography is a new diagnostic imaging method detecting the temperature change by the physiologic disturbance as compared with the radilogic method detecting the anatomical distortion. We have used liquid crystal thermography in 54 patients with complaining low back pain during the period form 2nd. March 1989 to 30th. April 1989. Of these 54 patients, 35 had myelography and C-T scan, 23 had EMG, and 13 were operated upon. 1. There were 35 clinically positive patients on whom concomitant myelography and C-T scan was performed; 32 patients(91%) had a positive myelography and C-T scan, and 30 patients (86%) had a positive thermography. Of these 35 patients, 23 had EMG concomitantly; 17 patients(74%) had a positive EMG and 18 patients(78%) had a positive thermography. 2. Liquid crystal thermography correlated with myelography and C-T scan in 31 patients(89%), EMG in 18 patients(78%). 3. Concomitant thermography, myelography and C-T scan, and surgery were performed on 13 patients among them EMG was added on 5 patients; Myelography and C-T scan had 100% accuracy, thermography had 92% accuracy, and EMG had 80 % accuracy. 4. Liquid crystal thermography is non-invasive method, dose not involve the use of ionizing radiation, and correlates well with clinical and surgical findings and other diagnostic methods, and costs relatively low. So, liquid crystal thermography is useful and reliable diagnostic method in patients with low back pain.

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.

By the human is getting older, the factors which can the reason of the aging process in the frontal region are divided, static factor and dynamic factor. the static factor is gravity, and the dynamic factor is repeatitive competition of depressosr muscles and elevator muscles. the depressor muscles are corrugator muscle, procerus muscle and orbicularis oculi muscle and the elevator muscle is frontalis muscle. Correction methods of this aging process are divided to non-surgical and surgical method. Non-surgical method are Atecoll and fat injection, and using botulinum toxin. But the effect of these method is temporary and limited, and if the skin laxity is great, this method cannot be used. Surgical methods are laser, chemical peeling, dermabrasion, classical forehead lift which is dissected superficial to galea aponeurosis or subperiosteal plane through coronal or hairline incision, and endoscopy method that the corrugator muscle and procerus muscle are transected by using endoscope, and then the posterior elevation of forehead flap is induced. the endoscopy method is the most popular method in recent years, which has the many advantages of minimal incision, less amount of bleeding and lower complication, but expensive equipment, adaptation and training period are needed. We present the result of 10 patients from May. 1996 to Jan. 1997. After the superior orbital rim exposed through upper eyelid incision, the corrugator muscle was resected while careful attention to the supraorbital n. which was located behind the orbicularis oculi muscle. A communication was made through both sided of medial canthal area, and after the procerus muscle was resected, the fat graft was inserted between them. Finally, we made periosteal incision superiorly, and subperiosteal forehead lift was done without using endoscope.

In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.
