It has been known that the interconnection between the gervous, endocrine and immune system are largely mediated through regulatory soluble factors such as neruopeptides, cytokines and hormones. Capsaicin, the pungent principle of hot peppers, is a neurotoxin that affects primary sensory neurons of the C and A-b type and depletes primary sensory neurons (polymodal nociceptors) of neuropeptides like tachykinin. In this study capsaicin was used to explore the possible role of the neruons on the expression of cellular and humoral immune responses and TNF-a prodcution. Mice were pretreated with s.c. injections in the neck region with a single dose of 100 u,g of capsaicin per mouse before immunization. ...continue...

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.

BACKGROUND: Thin hairs are critical to achieve natural result in female hairline correction surgery. However, there are few studies on the usefulness of hair thinning by intense pulsed light (IPL) after hairline correction surgery in East Asian females. METHODS: Hair thinning using IPL was performed in 54 women who had complained about thick hairs along the frontal hairline after hairline correction surgery. Patient mean age was 31.2 years old and patients were an average of 2.1 years post-hairline correction surgery. Initial treatment used 10 J, while second and third sessions were conducted with 10 to 15 J according to responsiveness to treatment. RESULTS: Mean thickness of individual hairs assessed before the procedure was 78.86 µm. The mean number of procedures was 1.6 per patient. Forty of 54 subjects (74%) achieved satisfactory hair thinning with only one procedure from 78.01 to 66.14 µm after treatment. The measured thickness was 66.43 µm at the end of the first year in patients who were satisfied after one procedure. Thirteen cases achieved satisfactory hair thinning after two sessions. Mean thickness was 74.44 µm and 67.51 µm, before and after the second session. One case required a third session with 15J, thinning from 89.00 to 66.50 µm. CONCLUSIONS: Hair thinning by IPL is a very useful method to provide a natural look after hairline correction surgery in East Asians, who have naturally thick hair.

The present study was undertaken to investigate the effect of acute administration of ethanol on production of cytokines such as IL-1j3, IL-2, IL-6, IL-10 and TNF-a, induction of penicillin V-induced active fatal anaphylaxis, and resistence to Salmonel/a typhimurium infection in mice. Ethanol administration into mice was performed by intraperitoneal injection of 0.5 ml of 20 % ethanol for 3 consecutive days before induction of cytokines with lipopolysaccharide (LPS), Con A or Salmone/la injection. Serum levels of cytokines were measured by ELISA. It was found that ethanol administration significantly inhibited both the serum levels of all cytokines examined and the resistance of mice to S. typhimurium. However, ethanol administration failed to prevent penicillin-induced fatal anaphylaxis. Taken together, the present results may need new insights in the diagnosis and treatment of various immunologically-mediated diseases.

"Capsaicin, the pungent principle of hot peppers, is a neurotoxin that depletes primary sensory neurons of neuropeptides like tachykinin. The objectives of these experiment was to examine the effects of capsaicin on Salmonel/a typhimurium-induced production of cytokines such as TNF-a, IL-1B, IL-6, IL-10 and IL-12 and on production of nitric oxide in peritoneal macrophages. In addition, the effects of capsaicin on survival rates of S. typhimurium-infected mice and on nuclear transcription factor (NF-kB) activation were also investigated. Mice were pretreated with a single s.c. injection of 100 ug of capsaicin and were infected i.v. with S. typhimurium (5xO5/mouse) in 0.2 ml volume after capsaicin pretreatment. The serum cytokine levels were measured 30, 60, 120, 180 and 240 min after Salmonella infection, using ELISA kits. The activation of NF-B was also examined by gel shift assay in spleens, thymuses and brains of mice that had been pretreated with a single s.c. injection of 100 ug of capsaicin. It was found that Sa/mone/la infection induced the production of TNF-a, IL-1B, IL-6, IL-10 and IL-12, but capsaicin pretreatment inhibited the production of TNF-a, IL-1B, IL-10 and IL-12, but enhanced IL-6 production 120 min after Salmonella infection. Interestingly, the capsaicin pretreatment inhibited the activation of NF-kB in spleens and thymuses. There were no differences in the numbers of bacteria in livers, brains, spleens, kidneys and lungs between capsaicin- pretreated mice and the control animals in applied experimental conditions. Suprisingly, however, capsaicin pretreatment increased both the survival rates of Sa/mone//a-infected mice and production of nitric oxide by peritoneal macrophages compared with capsaicin-untreated control mice. Taken together, these results indicate that the capsaicin-sensitive primary sensory neurons may play an important modulatory role in the production of cytokine, nitric oxide and NF-B activation and the pathogenesis of salmonellosis."

Korean Journal of Urology 2008;49(4):343-349
PURPOSE: We evaluated the effects of amitiptyline, as one of the first-line therapies, on the nocturia of patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Between June 2005 and December 2006, 50 patients completed this study(Group I=20, Group II=14, Group III=16). Group I was treated with doxazocin 4mg, group II was treated with doxazocin 4mg and tolterodine 4mg and the third group was treated with doxazocin 4mg and amitriptyline 10mg. We measured the treatment efficacy, the clinical parameters and we examined three days of the voiding diaries at baseline and after 4 weeks of treatment, respectively. RESULTS: After 4 weeks of treatment, all the patients had significant improvement for the International Prostate Symptom Score(IPSS) and the quality of life(QoL) score among the clinical parameters and they also showed improvement of their frequency of micturition per 24 hours, per night(nocturnal frequency) among the voiding diary parameters(p<0.05). For the post-treatment comparison of the nocturnal frequency, there was a significant difference between group I and group II as well as between group I and group III(p<0.05), and there was no difference between group II and group III(p>0.05). Although there was 1 case of mild dry-mouth in group II and 1 case of mild dry-mouth and drowsiness in group III, none of the patient dropped out due to side effects. CONCLUSIONS: We found significant improvement in the IPSS, the QoL score and the nocturnal frequency after treatment with amitriptyline 10mg. Therefore, amitriptyline 10mg would be helpful as a first-line therapy for BPH patients with nocturia.

Simple prostatectomy has been a mainstay of therapy for patients with benign prostate hyperplasia. In recent years, laparoscopic radical prostatectomy has emerged as a feasible treatment option for patients with localized prostate cancer. The advantages of laparoscopic procedures are minor surgical scars, shorter hospital stay, fewer analgesics utilization, and more rapid return to daily normal activities. We describe the use of laparoscopic resection of large hyperplastic prostate adenomas as an alternative to open prostatectomy.

Archives of Aesthetic Plastic Surgery 2019;25(1):42-44
The seated and prone positions are the most common surgical positions used during follicular unit extraction (FUE). Compared to the latter, the former eases centering and enables more optimal surgical field exposure due to gravitational effects on intraoperative bleeding. Furthermore, the surgeon can simultaneously work with multiple assistants, increasing efficiency and reducing operative time. During the harvesting stage of FUE, the patient is often seated in an electric height-adjustable salon chair. Such equipment, however, does not provide support for the head; maintaining a fixed upright position for an extremely long-lasting and delicate surgery that requires loupes with ×5 or higher magnification is challenging for both the surgeon and the patient. On the other hand, a support system that firmly fixes the patient's forehead would have ergonomic benefits during the process of FUE donor harvesting in a seated position. Firm support of the forehead would also enable upward traction to provide tension on the scalp, lessen the gap between the hair exit angle and internal hair angle, and reduce graft torsion, ultimately minimizing follicular injury and optimizing graft quality.
