We have examined the regenerative capabilities of the human scalp hair follicle after grafting the lower half of the follicle. Twenty-eight of 32 intact whole-hair follicles isolated from the human scalp regenerated hairs when grafted onto the forehead of the same person. Seven of the 15 lower-half follicles regenerated complete hair follicles 8 months after grafting showed that the lower-half follicle implant reconstituted the complete hair follicle. The sebaceous gland was not regenerated, but there was an outgrowth in the sebaceous gland regPark ion. Some grafts formed epithelial cysts. Two years after grafting, the histological examination of the regenerated follicle from the lower-half implant showed that the sebaceous gland was completely regenerated. While an intact follicle shows prominent naked shaft outgPark Park Parkrowth, the sheath grows concomitantly with the shaft in lower-half follicles in culture. If grafted lower-half follicles were located too deep, the regrown sheath could not reach the epidermal layer. In this situation, the formation of an epidermal cyst was likely.

BACKGROUND: It is well-known that organic solvents can cause various neurologic toxicities, and in particular, it had been reported that Parkinson's syndrome can be caused by organic solvents. CASE REPORT: A 53-year-old man who had worked for 13 years as a shipyard spray and brush painter and manifested with moderate cognitive disorder and was diagnosed with chronic toxic encephalopathy. We can assume he had had considerable exposure to organic solvents considering the estimates of the amounts of organic solvents in his work place. He had no specific medical history. The Minnesota Multiphasic Personality Inventory (MMPI) showed mild cognitive deficit, depression, and anxiety. Single Photon Emission Computed Tomography (SPECT) indicated a slightly decreased flow at the edge of the left temporal brain area, while T2 brain Magnetic Resonance Imaging (MRI) showed no specific signs except for ischemic changes in small vessels in the periventricular and subcortical white matter. He was also diagnosed with both carpal tunnel syndrome and peripheral neuropathy through a neuroconductive study. Several years later, he developed progressive bradykinesia and rigidity and, later, resting tremors in the left hand. He was diagnosed with Parkinson's disease and treated with dopaminergic agents, but there was no effect. After that, he was given deep brain stimulation, both. As a result, his tremor is improved. but, the rigidity remained. Three years later, He has continuously received dopaminergic therapy. but, he complains about tremors in both hands and more greatly reduced cognitive function. CONCLUSION: In this case, we assumed by patient's work history and exposure estimates that he was exposed to excessive levels of organic solvents. The clinical symptoms of this patient were very similar to those from Parkinson's disease, but the psychological symptom appeared earlier than the other symptoms and there was no response to dopaminergic agents. We conclude that this case is likely Parkinson's syndrome caused by organic solvents.

Twin reversed arterial perfusion (TRAP) sequence is a rare specific anomaly of twin gestation with fused placenta and umbilical anastomosis. This syndrome occurs once in about 34,600 births and reported first by Beneditti in 1533. We report on prenatal diagnosis of a case of TRAP sequence with color Doppler sonography, this case is presented with a brief review of the literature.

Ginseng root, as a folk medicine, has been used in for eastern countries for thousands of years. Ginseng extract has been shown to have a variety of effects on the activity of the central nervous system, promoting simulation as well as inhibition of the cortical activity. A survey of the relevant literatures has indicated that the putative anxiolytic activity of red ginseng has not been scientifically investigated. Therefore, the present study was designed to assess anxiolytic effect of ginseng total saponinis(GTS). The putative anxiolytic effects of several fractions of GTS were investigated in mice using an elevated plus maze paradigm. Single dose administration of TS Fr.- I showed anxiolytic action in mice. Anxiolytic effect induced by TS Fr.-I was similar to that induced by diazepam. TS Fr.-II, TS Fr.-III and TS Fr.-IV did not show the anxiolytic action compared with that of TS Fr.-I. It was suggested that regulation of GABAergic neurotransmission may be important in the action of GTS. The Interaction of GTS fractions with benzodiazepine receptor was performed using rat cortical membranes. GTS inhibited the binding of [3H] Rp 15-1788 on the benzodiazepine receptor. Among from TS fractions, the binding activity of GTS in the TS Fr.-IV was highest, which did not show the anxiolytic activity. From these results, we conclude that GTS has anxiolytic action, and the is not related to benzodiazepine receptor binding activity.

Although extrahepatic metastasis of hepatocellular carcinoma are frequent as about 64%, implants involving the peritoneum are rare. We presented a cases, whieh is hepatocellular carcinoma with metastasis to visceral peritoneum revealing multiple, hard, variable-sized and nodular mass including large mass over 10 cm in size. The presence of tumor was diagnosed by serum alpha fetoprotein, abdaminal CT, celiac and SMA angiography and biopsy with laparoscopy.

BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

STUDY DESIGN: Case study of two cases. OBJECTIVES: The aim of our study is to describe atypical patterns of tuberculous spondylitis. SUMMARY OF LITERATURE REVIEW: Few reports of tuberculous spondylitis have discussed atypical cases, which resulted in a poor prognosis due to the delay in early diagnosis and proper treatment. MATERIALS AND METHODS: A 74-year-old female underwent an incision and drainage, and posterior decompression and fusion (PDF) due to tuberculous epidural abscess after vertebroplasty of a compression fracture at T12. A 52-year-old female underwent interbody fusion and posterior lateral fusion (PLF) because of aggravation of an abscess and neurologic symptoms following non-invasive intervention to treat atypical tuberculous spondylitis. RESULTS: Clinical symptoms and serological tests of the patients were improved at postoperative 6 months. CONCLUSIONS: When a patient presents with focal bony or soft tissue abnormality on an image study, the possibility of non-typical tuberculous spondylitis has to be considered when infective spondylitis or a tumor is detected. Moreover, an invasive diagnosis tool such as biopsy will be needed for proper management.
