Capsaicin, the pungent principle of hot peppers, is a neurotoxin that depletes unmyelinated primary sensory neurons (polymodal nociceptors) of neuropeptides like tachykinins. However, the role of capsaicin-sensitive sensory nerve in the production of cytokines, penicillin V (PEV)-induced active fatal anaphylaxis and other immune responses is not yet fully established. Neonatal mice were pretreated s.c. with a single injection of 10 ug of capsaicin per mouse in volume of 20 ul within 5 days of age. Using 5-8 week old mice pretreated as neonates with capsaicin, the capsaicin- pretreated and vehicle-treated control mice were examined for various parameters of immune responses described above. For the induction of active fatal anaphylaxis with PEV, 8 week old mice pretreated as neonates and age-matched capsaicin- untreated control mice were sensitized i.p. with 500 ug of PEV-ovalbumin conjugate plus 2*10(9) B. pertussis and 1.0 mg alum and challenged i.v. with PEV-bovine serum albumin conjugate 14 days later. It was found that neonatal capsaicin-pretreatment significantly enhanced contact hypersensitivity to TNCB and hemagglutination response to SRBC, but significantly inhibited the proliferation response of rnurine splenocyte to Con A and LPS. Interestingly, neonatal capsaicin pretreatment significantly inhibited the intensity of PEV-induced active fatal anaphylaxis and decreased the mortality due to anaphylactic shock. It also significantly inhibited LPS- induced production of cytokines such as TNF-a, IL-1B, IL-6, IL-10, and IL-12. The capsaicin-pretreatment also resulted in an inhibition of the activation of NF-kB. Taken together, these data showed for the first time that neonatal capsaicin-pretreatment significantly inhibited an antibiotic (PEV)-induced anaphylaxis and production of various cytokines, and suggest that capsaicin-sensitive primary sensory nerve may play an important regulatory role in active fatal anaphylaxis and cytokine production, thus potentially presenting tools for immune intervention. In particular, the data presented also indicated the possibility to selectively down-modulate cytokine production and NF-kB activation may offer a broad application for therapeutic intervention in neuroimmunological diseases and other pathological situations.

The ideal breast reduction should create beautiful breasts with limited scars. Unfortunately, no surgeon has ever been able to produce such a result. Most recent breast reduction techniques tend to produce minimal breast scars and avoid the classic inverted-T incision. The vertical mammaplasty can be used in mild to moderate cases of breast reduction, producing consistently good, stable results with limited scars. This technique uses adjustable preoperative markings, an upper pedicle for the areola, and a central breast reduction with limited skin undermining. The shape of the breast is created by suturing of the gland and does not rely on the skin. The adjunctive use of liposuction in fatty breasts can be considered safe and efficient. We have performed reduction mammaplasty using the vertical mammaplasty technique in 12 patients. Overall number and extent of complications were small, and patient satisfaction was high for this procedures. The advantages of vertical mammaplasty technique compared with other methods are as follows ; 1. The markings are adjustable to nearly all patients. 2. Stable contours are produced because the gland is strongly sutured. 3. Few postoperative complications occur. 4. Limited scars(only vertical scars) are created 5. The procedure is easy to learn and perform.

PURPOSE: It is not clear that the development of glomerular injury and aggravation by tumor necrosis factor alpha (TNF-alpha) is related to intrarenal or serum concentration of TNF-alpha. So, we studied the relationship between the concentration of TNF-alpha and aggravation of glomerular damage in the Henoch-Schonlein nephritis(HSN) and idiopathic nephrotic syndrome(INS). METHODS: We collected the sera and urines of 21 patients with Henoch-Schonlein purpura(HSP) and 22 patients with INS visited Chungbuk National University hospital from March 1998 to March 2001. The concentration of TNF-alpha in the sera and urines were measured by sandwich ELISA. RESULTS: Serum TNF-alpha levels in the HSP patients with renal involvement were significantly higher than those without renal involvement(P=0.009). But urine TNF-alpha levels have no correlation with renal involvement(P=0.088). In the HSN patients, proteinuria have a significant correlation with serum TNF-alpha levels(P=0.004) but less correlation with urine TNF-alpha levels(P=0.053). Otherwise, proteinuria have no correlation with serum TNF-alpha levels(P=0.763) but have a significant correlation with urine TNF-alpha levels(P=0.007) in INS. CONCLUSION: These result suggest that the serum concentration of TNF-alpha would be important to glomerular involvement in HSP. And, it is interesting that proteinuria shows a significant relation with serum TNF-alpha levels in the HSN, but with urine TNF-alpha levels in the INS. This means the major production of TNF-alpha may be originated by extrarenal inflammation in the HSN and by intrarenal tubulo-interstitial damage due to proteinuria in the INS.

The mandibular contour determines the shape of the lower part of face and thus influences the appearance of head and neck. A prominent mandibular angle produce characteristic quadriangular, coarse and muscular appearance. To correct this facial contour to oval shape, the prominent angle can be contoured. the cutaneous approach has been used, but it leaves noticeble scar and has risk of facial nerve injury. Thus the intraoral approach has been used commonly. But because of restricition of operation field, the intraoral approach disadvantages of long operation time, high risk of complications. So, we have performed mandibular contouring procedure by new approach which uses reciprocating saw through stab incision under the mandibular body to correct the 9 patients of mandibular angle protrusion who visited our clinics recently. And we found that mandibular angle contouring by this new approach is easy, and makes the operation and recovery time shorter. There were no complications and cosmetic results were quite satisfactory.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

A 38-year-old woman was presented with a dark brown plaque on the abdomen. Clinically, the tumor was simulating the appearance of dysplastic nevus. Microscopically, the cells of the stratum malphighii lay in a disordered pattern. Many cells in the epidermis were atypical and melanin pigment was mainly in the basal layer of the epidermis and the upper dermis. Diagnosis of pigmented Bowen's disease was made. Pigmented Bowen's disease is rarely found at body sites other than the anogenital area.

Apocrine poroma is a benign cutaneous adnexal neoplasm differentiating in the direction of sebaceous and apocrine glands, and follicular germs. The clinical appearance of apocrine poroma is not distinctive, and the histologic finding is similar to that of eccrine poroma, which is typified by proliferation of poroid and luminal cells in continuity with the epidermis. But sebaceous, apocrine or follicular differentiation may also be found in the case of apocrine poroma. We herein report a case of apocrine poroma on the scalp. This case exhibited apocrine and sebaceous differentiation, and connection to an adjacent follicular epithelium.

Mixed tumor of the skin (chondroid syringoma) is a rare benign tumor composed of epithelial elements intermingled with myxoid or cartilagenous stroma which is not separated by basement membrane. It had been believed to originate from the eccrine gland but recently, it was described to be of apocrine gland origin in case of showing apparent apocrine secretion. We report on a 63-year-old man with a tumor on the right upper eyelid showing typical microscopic features of mixed tumor of the skin. Many apocrine decapitation secretions were seen in tubular structures and follicular differentiations were also seen, which represents the common origin of folliculo-sebaceous-apocrine unit.

Blue nevus is a benign melanocytic neoplasm and represents itself usually as a solitary blue or blue-black papule. It rarely occurs as multiple lesions grouped in a circumscribed area. How-ever, non-grouped disseminated blue nevi are exceedingly rare. We report a patient with acquired multiple blue nevi that was distributed over the entire body discretely and showed an increase in the number of the nevi without any causal factors.

OBJECTIVE: To examine the synergistic effects of both computer-assisted cognitive rehabilitation (CACR) and transcranial direct current stimulation (tDCS) on cognitive function in patients with stroke. METHODS: The current double-blind, sham-controlled study enrolled a total of 11 patients who were newly diagnosed with stroke. The patients of the tDCS group (n=6) completed sessions of the Korean computer-assisted cognitive rehabilitation program five times a week for 30 minutes a session during a mean period of 18.5 days concomitantly with the anodal tDCS over the bilateral prefrontal cortex combined with the CACR. The patients of the control group (n=5) also completed sessions of the sham stimulation during a mean period of 17.8 days. Anodal tDCS over bilateral prefrontal cortex (F3 and F4 in 10-20 EEG system) was delivered for 30 minutes at an intensity of 2 mA. Cathode electrodes were applied to the non-dominant arm. All the patients were evaluated using the Seoul Computerized Neuropsychological Test (SCNT) and the Korean Mini-Mental State Examination. RESULTS: Mann-Whitney U test revealed a significant difference between the two groups. The patients of the tDCS group achieved a significant improvement in the post/pre ratio of auditory continuous performance test and visual continuous performance test on the SCNT items. CONCLUSION: Our results indicate that the concomitant use of the tDCS with CACR to the prefrontal cortex may provide additional beneficial effects in improving the cognitive dysfunction for patients with stroke.
