  • Objectives: Frey's syndrome is an infrequent complication after parotidectomy and its incidence varies from 23.5% to 50.8% in the literature. The objective of this study was to evaluate the actual incidence and clinical characteristics of Frey's syndrome. Methods: We analyzed 31 patients who underwent parotidectomy and serial Minor's starch-iodine test. The mean follow-up period was $66{\pm}26.1$ months (range, 24-118 months). The Frey's syndrome was analyzed using a questionnaire for the assessment of the subjective symptom and Minor's starch-iodine test for the objective measurement at 1, 3, 6, and 12 months after the surgery and then every 6 or 12 months. Minor's starch-iodine test was graded from 0 to 3 according to the area of discolorization. Results: Frey's syndrome occurred in 11 patients (35.5%) on the Minor's starch-iodine test. The mean onset of Frey's syndrome on the starch-iodine test was $13.6{\pm}10.4$ months after parotidectomy. Sixteen patients (51.6%) complained about gustatory sweating and flushing. The onset of the subjective symptom was $11.27{\pm}6.96$ months after the surgery. There was a significant correlation between the grade of the starch-iodine test and the severity of subjective symptoms (P <0.001). Various factors including size and location of tumor, incision method, and extent of parotidectomy did not correlate with the Frey's syndrome. Conclusion: The incidence of Frey's syndrome was 35.5% on the Starch-Iodine test, and the onset was about postoperative 13.6 months.

  • Soft X-ray is useful to identify the quality of fresh ginseng causing the inside cavity or white pan of red ginseng. The portion of low mass density identified by the difference in absorption of soft X-ray showed lower dry matter density and less or no response to iodine test indicating less accumulation or excess consumption of starch. The inside white part of red ginseng absorbed less X-ray than the normal part did. Probability for identification of the inside cavity or white at fresh ginseng was rather high (80-90%) in screen observation than f'3m reading and seemed to be increased further by using the developed screen and with training. The inside white of red ginseng appeared to be due to starch deficiency. Dry matter density appeared to be better than fresh weight density for the quality criterion.

  • Background : Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, and in some instances, staining of clothes that may socially and psychologically impair affected individuals. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneous pulsed neodymium: yttrium-aluminum-garnet (Nd-YAG) laser treatment for the treatment of axillary osmidrosis. Methods : Twenty-nine patients with axillary osmidrosis were included in this study. Patients were categorized according to the results of an axillary malodor grading system, and a subcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for the appropriate distribution of laser energy was determined using the iodine starch test (Minor's test) against a grid pattern composed of $2{\times}2cm$ squares. The endpoint of exposure was 300 to 500 J for each grid, depending on the preoperative evaluation results. The results were evaluated by measurement of axillary malodor both pre- and postoperatively using the grading system and iodine starch test. Results : The average follow-up period was 12.8 months. Nineteen patients had a fair-to-good result and ten patients had poor results. The postoperative Minor's test demonstrated that there were remarkable improvements for patients with mild to moderate symptoms. Complications including superficial second degree burns (n=3) were treated in a conservative manner. A deep second degree burn (n=1) was treated by a surgical procedure. Conclusions : Subcutaneous pulsed Nd-YAG laser has many advantages and is an effective noninvasive treatment for mild to moderate axillary osmidrosis.

  • Sugars in Korean and Japanese pumpkin were studied. The sugars in pumpkin were crushed and extracted by boiling for 30 min. Korean pumpkin was found to contain 0.41% of sucrose, 0.54% of fructose, 0.61% of glucose and 0.68% of starch. Japanese pumpkin was found to contain 2.60% of sucrose, 2.76% of fructose, 1.91% of glucose and 1.22% of starch. No other mono- and oligosaccharides were detected in the test of TLC and HPLC. Starch in Japanese pumpkin showed only signal of $\alpha$-1,4-glucosidic linkage by proton NMR analysis, and showed 86% of absorbance by iodine reaction compared with amylose(DP 117). These results indicated that starch in Japanese pumpkin is composed by only amylose. Pectin contents of Korean and Japanese pumpkin sowed 6.29% and 2.67%, respectively, as galacturonic acid by carbazole analysis.

  • Purpose: Several therapeutic approaches have been introduced and tried to treat Frey syndrome following parotidectomy. However they were not proved as an effective treatment. A new therapeutic modality using botulinum toxin injections was presented previously by several study groups. But, the duration of the demonstrated positive effect was essentially unknown so far. The purpose of this clinical investigation is to demonstrate the effectiveness of Botulinum toxin type A(BTXA) in patients with Frey syndrome. Methods: For this study, 12 patients were treated, They were assessed with the Minor's iodine-starch test and interviewed before and after treatment. Botulinum toxin is injected with $1.0cm^2$ apart into the skin where symptoms of Frey's syndrome has manifestated. The patients were classified according to the concentration of botulinum toxin and dosage of botulinum toxin. Results: The outcome measures were the time of reappearance of gustatory sweating(subjective study), and the results of an Minor's iodine-starch test(objective study) of 3 weeks, 3 months, 6 months, 9 months, 12 months after treatment. This treatment was effective in all groups of patients. The concentrations and the amount of dosages did not affect the treatment. But high concentration produced faster effectiveness in subjective. Conclusion: Botulinum toxin type A(BTXA) for Frey syndrome is easy, convenient and effective withouts severe complication. And the patients has no difficulty and limitation in their life.

  • Conventional thoracoscopic sympathectomy is an effective method in treating palmar-axillary hyperhidrosis. However, this may result in a postoperatively compensatory hyperhidrosis. Conservative treatments of compensatory hyperhidrosis consist of aluminum chloride, anticholinergics, iontrophoresis, and botulinum toxin A injections. Surgical treatments in compensatory hyperhidrosis include excision of axillary tissue, liposuction, and thoracoscopic sympathectomy. Intradermal injection of botulinum toxin A has used to treat focal axillary or palmar hyperhidrosis. Botulinum toxin A bestows significant benefits with few side-effects and is well-tolerated, with beneficial results lasting from 4-16 months. We report a case illustrating the beneficial use of botulinum toxin A in a 25-year-old healthy male patient with compensatory sweating of the flank after thoracoscopic sympathectomy. Modified Minor's starch iodine test was used to allow accurate assess the impact of hyperhidrosis on the patient. In conclusion, Botulinum toxin type A is a valuable therapy for compensatory sweating after endoscopic thoracic sympathectomy.

  • Embryogenic calluses derived from shoot apical meristem explants of sweetpotato were subjected to particle bombardment to generate transgenic plants for antisense expression of cDNAs encoding two different AGPase small subunit (ibAGP1 and ibAGP2). Plants were generated via somatic embryogenesis. PCR and Southern analysis demonstrated that the incorporation of ibAGP1 and ibAGP2 into the genome in an antisense orientation. Immunoblot analysis confirmed reduced levels of AGPase small subunit in transgenic plant leaves. Plants with both ibAGP1 and ibAGP2 produced a lower level of the protein than plants with ibAGP1 alone. iodine test demonstrated that transgenic plant leaves and storage root accumulated reduced amounts of starch. Iodine staining of leaf tissues indicated that transgenic plants accumulated less amount of starch than control. In accordance with western blot analysis, plants with both ibAGP1 and ibAGP2 accumulated a lower amount of starch than plants with ibAGP1 alone. Both transgenic plants exhibited a severely retarded growth, resulting in bare survival. It is suggested that disrupted expression of the gene encoding AGPase small subunit is lethal to the growth of sweetpotato contrast to other species including potato.

  • The in vitro activity of penicillins(penicillin G, ampicillin, carbenicillin, methicillin and cloxacillin) and gentamicin to Staphylococcus aureus and coagulase-negative staphylococci isolated from bovine mastitic milk samples was determined. The growth of all isolates of staphylococci tested was inhibited by cloxacillin and methicillin at a concentration of $0.78{\mu}g/ml$ and by gentamicin at a minimum inhibitory concentration (MIC) of $1.56{\mu}g/ml$. Of the 140 strains of Staphylococcus aureus isolated 99(70.7%) gave positive reactions for penicillinase on the starch-iodine test. Of 121 isolates of coagulase-negative staphylococci, 58(47.9%) showed penicillinase production, but all the Staph. xylosus lacked the ability to produce penicillinase. MIC of penicillin G of the penicillinase-positive strains was $0.2{\mu}g/ml$ or more. The combination of cloxacillin with gentamicin showed a synergistic effect by inhibiting regrowth of the tested organism.
