Background The survival rate of newborns with severe congenital abdominal wall defects has increased. After successfully addressing life-threatening complications, it is necessary to focus on the cosmetic and functional outcomes of the abdominal wall. Methods We performed a chart review of five cases treated in our institution. Results Five patients, ranging from seven to 18 years of age, underwent the following surgical approaches: simple approximation of the rectus abdominis fascia, the rectus abdominis sheath turnover flap, the placement of submuscular tissue expanders, mesh repair, or a combination of these techniques depending on the characteristics of each individual case. Conclusions Patients with severe congenital abdominal wall defects require individualized surgical treatment to address both the aesthetic and functional issues related to the sequelae of their defects.

Background Cranially-based nasolabial flaps are a good alternative for the reconstruction of nasal defects. Methods A cranially-based nasolabial flap was used in 18 patients to reconstruct defects of the nose from 2010 to 2016, and the long-term results are presented in this report. Results Fifteen of the flaps completely survived. All the patients had a bulky appearance, but they did not want to undergo a second operation for cosmesis. The dissection of the flap took approximately 20 minutes, and the total operation lasted for 1 hour. The patients were hospitalized for 1-7 days, and the postoperative follow-up period was 1-28 months (mean, 17 months). Conclusions The cranially-based nasolabial flap possesses all the advantages of the traditional forehead flap, and can safely be used in selected cases.

Stevens-Johnson syndrome (SJS) is a rare disease in which extensive toxic epidermolysis occurs after medication. Skin and mucous membranes are involved in about 90% of SJS cases, and webbing of mouth corners (microstomia) may occur when they are affected. Few reports have been issued on microstomia in SJS, and no consensus has been reached regarding treatment methods, timings, or results. We encountered a case of microstomia following SJS after ofloxacin medication in a 22-year-old woman treated by commissuroplasty using a lozenge-shaped excision. We present an appropriate correction method and surgical timing for microstomia following SJS.

Microvascular anastomosis is too important to reduce the failure in operating room because of no choice in case of failure and prognosis of the failure would be more worse than any other success ones. Factors for microsurgery trainee influencing patency in microvascular anastomosis at the laboratory are numerous but three basic prerequisites are magnification, instruments and suture material and training. First Author trained microsurgical technique to the second author using femoral artery of the rat and patency of the anastomosis was evaluated by the milking test. Period which microsurgeon successes femoral arterial anastomosis in rat in both of 5 and 30 minutes was 7th week at the laboratory which has done 2 vessels a week under the supervise of the skilled first author.

Purpose : To assess the clinical results of second toe-to-finger transfer in traumatic amputated index finger. Materials and Methods : For the clinical evaluation, we have analyzed 12 patients with ROM of finger joints, pinch power, static two point discrimination, life functional assessment, and patient's satisfaction. Results : In genral ROM was $54.4^{\circ}$ at MP joint, $17^{\circ}$ at PIP joint and $6.7^{\circ}$ at DIP joint. Pinch power was good in 3 cases, fair in 7 cases, and poor in 2 cases. Daily life activity and patient's acceptance were satisfactory. Conclusion : Although transfered toe function may be poorer than normal finger, the hand was restored to a useful, sensate and versatile functional unit.

Lateral arm flap has been used for the reconstruction of the various defects in hand, head and neck region. This flap is highly dependable as a free flap because of its thin flap thickness, constant vascular anatomy and possibility of osteocutaneous flap and fascial flap. Recently, many authors tried extended approach for vascular pedicle and distal flap extension for bigger defects. In this study, we review previous articles and 14 cases used lateral arm flaps for coverage of the varying defect on head and neck, upper and lower extremities succesfully. In conclusion, lateral arm flap has constant anatomical structure and can overcome the disadvantages such as short pedicle length and limited flap size, then the range of its application can be very widened.

The rectus abdominis myocutaneous flap is frequently used in the field of plastic and reconstructive surgery such as breast reconstruction and as a donor of free tissue transfer. Major problems with this flap is bulkiness, the possibility of postoperative abdominal herniation and muscle weakness following the removal of the rectus abdominis muscle. We used paraumbilical perforator based skin flap fed by a muscle perforator from the deep inferior epigastric artery, with no or little muscle and fatty tissue, in three patients for the resurfacing of relatively wide and thin defects. This technique has all of the advantages of the conventional rectus abdominis myocutaneous flap with decreased possibility of postoperative abdominal herniation or muscle weakness. Another challenging merit is possibility of skin flap thinning.

The present study was undertaken to determine the inhibitory effects of cholane compounds, unsodeoxycholic acid (UDCA) and chenodeoxycholic acid (CDCA) on the development of morphine-induced tolerance and physical dependence, and also to determine the hepatic glutathione contents. UDCA and CDCA inhibited the development of morphine-induced tolerance and physical dependence significantly. UDCA inhibited the hepatic glutathione decrease induced by morphine multiple injections, while this effect was not observed in CDCA treated mice. It was throught that the inhibitory effects of hepatic glutathione decrease in morphine-treated mice by UDCA and CDCA showed a tendency of inhibitory effects of development of morphine tolerance and dependence.

N-Aryl-N'(4-hydroxy-6-methyl-2-pyrimidinyl)guanidines (IIa-c) were prepared by cyclization of N-arybiguanides (Ia-c) with ethyl acetoacetate. Coupling of compounds (IIa-c) with the appropriate diazotized arylamine gave N-aryl-N'-(5-arylhydrazono-6-methyl-4-oxopyrimidin-2-yl) guanidines (IIIa-f). Whereas, their chlorination with phosphorus oxychloride followed by treatment of N-aryl-N'-(4-Chloro-6-methyl-2-pyrimidinyl)guanidimes (IVac) with the appropriate arylamine afforded the corresponding 4-arylamino derivatives (Vaf). Compounds (IIa-f) were also formed when compounds (1a-c) were treated with ethyl 2-arylhydrazono-3-oxobutyrates. The antimircobial testing of some of the prepared compounds against some pathogenic microorganisms revealed that only two have a marked effect against Escherichia coli.

This work includes the synthesis of 15 final compounds (6a-h and 7b-h) as prod rugs of 5-ASA in the form of the acid itself, esters and amides linked by an amide linkage through a spacer to the endocyclic ring N of nicotinamide. Also, 15 new intermediate compounds were prepared. The target compounds (6b, 6f, 7b, and 7e-h) revealed potent analgesic and anti-inflammatory activities in comparison to sulfasalazine and 5-ASA. In addition, ulcerogenicity, $LD_{50}$, in vivo and in vitro metabolism of compound 7f were determined.
