Penetrating keratoplasty was performed in six eyes of granular corneal dystrophy. Vision was improved from worse than 0.05 to better than 0.4. Mean follow-up period is 14 months (12-18 months). Corneal deposits were stained for H and E. Masson trichrome, Wilder's reticulin and Luxol fast blue but not for PAS, Congo red and Oil red a stain. Electron micorscopic examination showed that polymorphic, electron dense rod-shaped bodies were present in the Bowman's layer and between stromal lamellae and in the interceliular space of corneal epithelium. And, for the first time we found a area looked like a transformation from normal stroma to the granular deposit.

Amyloidosis is characterized by the deposition of extracellular fibrillar proteins in various tissues. Amyloidosis in the head and neck is a rare and benign condition that usually takes the form of localized amyloidosis. Among primary sites of head and neck area, nasopharyngeal amyloidosis has proven to be rare and there are only about ten cases that have been reported in the literature worldwide until today. We report a case of localized nasopharyngeal amyloidosis. Histopathologic examination of the mass revealed findings consistent with amyloidosis, which were stained with Congo Red. The postoperative recovery was uneventful. At the present time, the patient has no evidence of disease or recurrence and complication.

To obtain basic information on the detection of cellulolytic activity in Auricularia auricula-judae, the influences of dye reagent, pH, and temperature were assessed. Chromogenic dye (congo red, phenol red, remazol brilliant blue, and trypan blue) was individually incorporated into a medium containing either carboxymethyl-cellulose, Avicel, or D-cellobiose as a polysaccharide carbon substrate. The other assessments utilized pHs ranging from 4.5 to 8.0 and temperatures from 15~35degrees C. Overall, when A. auricula-judae species were transferred onto media contained Congo red and adjusted pH 7.0 and then incubated at 25degrees C for 5 days, the clear zone indicative of cellulolytic activity was more pronounced.

OBJECTIVES: This study aims to evaluate the economic efficiency of a nutrition management program for children under 5 years of age in Kenge, Kwango District, Democratic Republic of the Congo (DR Congo) from 2014 to 2016. METHODS: The economic efficiency of a nutrition management program for children under 5 years of age who have recovered from malnutrition status was evaluated using a cost-benefit analysis. The costs were analyzed according to the executed budget incurred during the project period. The benefits were estimated as the monetary value of the saved lives of children under 5 years of age. The economic efficiency of the program was determined by the Benefit-Cost Ratio (BCR). The BCR was calculated by dividing the total discounted benefit by the total discounted costs. The project is economically efficient when the BCR is greater than 1. RESULTS: The costs of the nutrition management program were calculated as 1,677,609,648 Korean Won (KRW). A total of 2,466 children survived with improved malnutrition status through this program. The benefit for the reduction of mortality for children under 5 years of age was estimated to be 6,814,354,467 KRW, the estimated value of life for 2,466 children. The BCR was 4.06. CONCLUSIONS: The nutrition management program for children under 5 years of age in DR Congo was found to be a cost-effective project. Successful and efficient Official Development Assistance (ODA) for a health project requires integrated and comprehensive strategies and specialized international development consulting to improve efficiency. Future nutrition management programs should take into account the national health program to maintain the sustainability of the project.

To evaluate which dye is effective in a plate assay for detecting extracellular cellulase activity produced by fungi, four chromogenic dyes including remazol brilliant blue, phenol red, congo red, and tryphan blue, were compared using chromagenic media. For the comparison, 19 fungal species belonging to three phyla, ascomycota, basidiomycota, and zygomycota were inoculated onto yeast nitrogen-based media containing different carbon substrates such as cellulose (carboxylmethyl and avicel types) and cellobiose labeled with each of the four dyes. Overall, the formation of clear zone on agar media resulting from the degradation of the substrates by the enzymes secreted from the test fungi was most apparent with media containing congo red. The detection frequency of cellulase activity was also most high on congo red-supplemented media. The results of this study showed that congo red is better dye than other three dyes in a plate assay for fungal enzyme detection.

A 38-year-old male patient visited our clinic complaining of three skin lesions on the scalp. There were yellowish to brownish, waxy, non-tender, walnut-sized nodules. Hematoxylin and eosin staining revealed amorphous pinkish material deposits in the dermis. The Congo red stain and Dylon stain under polarizing microscopy showed yellow-green birefringence and the immunoglobulin-lambda light chain stain showed a positive reaction. An electron microscopic examination revealed filaments with uniform diameter(6 to 10nm) that were straight and neither branched nor anastomosed. Based on the clinical, histopathological, immunohistochemical and electron microscopical findings, the skin lesions were diagnosed as nodular amyloidosis.

9.Primary Systemic Amyloidosis involved the Conjunctiva.
Journal of the Korean Ophthalmological Society 1991;32(8):604-608
Amyloid may involve the conjunctiva without deposits of the skin of the eyelid in primary localized amyloidosis, but extremely rare in primary systemic amyloidosis. We describe the clinicopathologic features of a case of primary systemic amyloidosis which invloved the conjunctiva and larynx. A 58-years-old woman presented a conjuctival mass of the left eye. Slit lamp microscopy showed a pinkish, flat elevated mass on the bulbar conjunctiva, fornix, and upper tarsal conjunctiva. There was no history of antecedent ocular or systemic diseases. She had undergone total laryngectomy for laryngeal amyloidosis. Microscopically, a pale amorphous eosinophilic material was deposited in the subcojunctival tissue. The deposit showed metachromasia with crystal violet, and dichroism and birefringence in polarized light following Congo red staining. Electron microscopically amyloid was comprised of linear add non-branching fibrils, which were about 11nm in width.

Amyloidosis is a disease complex associated with deposition of insoluble filbrillar protein in various tissues of the body. Cutaneous lesions are present in up to 40 % of patients with primary and myeloma associated systemic amyloidosis. We present a case of systemic amyloidosis associated with multiple myleoma occuring in 54-year-old male who had waxy papules with petechiae on nasola bial fold, postauricular area, and cheek. The diagnosis was confirmed by Congo red stain, electron microscope, immunelectrophoresis, Bence-Jones proteinuria, immunoperoxidase stain, and bone marow biopsy.
