Stings due to jellyfish, sea anemones, and corals are the most common envenomations encountered with humans in the marine environment. The first case was a 36-year-old female who presented with multiple whiplike linear, dark reddish bullous eruptions on the right forearm after she was stung by a jellyfish in the Philippines 15 days previously. The patient was treated with oral antibiotics for 10 days, but severe pruritus persisted and new papular lesions developed on her hand. Antibiotic therapy was discontinued and oral and topical corticosteroid therapy was applied instead. The skin lesions disappeared without recurrence after about 4 weeks. The second case was a 29-year-old male who visited our department with linear, reddish patches and necrotizing blisters on both the arms, left thigh, and trunk after he was stung by a jellyfish in Thailand. We treated him with oral and topical corticosteroids for 10 days and the lesions cleared. We describe two typical cases of jellyfish sting that are rare in Korea.

Aims: Coral diseases have emerged over the last several decades, causing a loss of live coral cover in the Caribbean and Indo-Pacific reefs. Hence, microbiological and disease cultural techniques are commonly used to investigate their causative microbial agents. This is the first study to identify the potential of pathogenic Vibrio spp. isolated from apparently white syndrome (WS) coral disease in Tioman Island Marine Park using biochemical and molecular techniques. Methodology and results: The Vibrio colonies were isolated from 108 samples of WS infected corals (Acropora cytherea and Montipora aequituberculata) including seawater, sediment and algae found adjacent to infected coral colonies. A total of one hundred representative Vibrio isolates were characterized and most of them (n=50) were identified as V. vulnificus, V. alginolyticus and Photobacterium damselae following biochemical analysis. The molecular analysis revealed six Vibrio spp. (V. coralliilyticus, V. hepatarius, V. brasiliensis, V. tubiashi, V. campbellii, V. ishigakensis) and one Photobacterium rosenbergii. Vibrio coralliilyticus isolated from all infected coral samples may be highly responsible for the sign of WS disease. Conclusion, significance and impact of study The findings of this study provide baseline data and information on potential coral pathogens identified in the coastal waters of Tioman Island. Etiological disease study is suggested to validate their severity and virulence factors in the future.

Contact with coral may cause a rare type of contact dermatitis, and the resulting skin reaction can be divided into different reactions: the acute, delayed and chronic types of coelenterate dermatitis. Granulomas of delayed skin reactions have rarely been reported. Herein, we report on a rare case of a delayed reaction of the skin to coral injury, and the patient displayed superficial granulomas and atypical CD30+ lymphocytes.

Several indices have been developed that use bleeding and color changes as indicators of early gingival pathology. In the presence of gingivitis, vascular proliferation and reduction of keratinization owing to increase redness in gingiva. Descriptions of healthy gingiva are numerous, ranging from pale pink and coral pink to deep red and violet. This terms are not objective. Because of perception of color depends on a lot of factors such as light source, object, observer and so on. It is difficult to make an objective expression. Therefore the using of mechanical equipment is recommended to exclude these variables and observer's vias. The purpose of this study was to evaluate gingival color change after scaling & subgingival root planing. The other purpose of this study was to research the correlation of pocket depth, P.B.I. score and gingival color change. After photo-taking and storaging the image of gingival color into a computer, color change was examine with an image analysis program. Results were as follow; 1. Color of healed gingiva after scaling & subgingival root planing was significantly differ from color of inflamed gingiva(p<0.01). 2. Color of healed gingiva after scaling was similar to color of healed gingiva after subgingival root planing(p<0.05). 3. There was statistically significant correlation between color change of red component and pocket depth after scaling & subgingival root planing(p<0.01) 4. There was no correlation between color change of green, blue component and pocket depth after scaling & subgingival root planing(p<0.01) 5. There was statistically significant correlation between between color change of red component and P.B.I. score after scaling & subgingival root planing(p<0.01). 6. There was no correlation between color changes of green, blue component and P.B.I. score after scaling & subgingival root planing(p<0.01) 7. Increase of pocket depth and P.B.I. score were significantly correlated to the amount of color change(p<0.01). 8. P.B.I. score had a higher correlation with color change than pocket depth(p<0.01).

A case of porphyria cutanca tarda is reported, in which the photosensitive cutaneous symptoms developed in association with impaired hepatic function possibly related to chronic consumption of alcohol. Wood's light examination of the urine revealed coral red fluorescence, and qualitative chemical urinalysis was strong positive for uroporphyrin and coproporphyrin. Biopsy of the skin showed subepidermal bulla with festooning arrangement of the naked papillae and basophilic degeneration of the dermis. The patient's favorable response to alkalinization therapy by sodium bicarbonate per os is encouraging, even for a short period's observation. Clinical, histopathological, and biochemical features of this disease are also discussed.

The purpose of this study was to observe bone apposition and marginal bone loss and to check the possibility of success on titanium implant, HA coated implant and the implant with natural coral that were place immediately after teeth extraction in dogs. Experimental subjects were divided into 4 groups ; the 1st group is the titanium implant, second the HA coated implant, third the implant with natural coral, and the last the control group that was prepared in the extraction sockets. After 12 weeks, the dogs were sacrificed for visual observation and microscopic examination approaching histologic and histomorphometric analysis. The results were as follows : 1. Neither the infection nor the exposure of implant was found at the sites of all implant. 2. In a histomorphometric analysis, mean percentage of direct bone contact with the titanium implant was 80.7% and the HA coated implant showed 81.5% apposition, but the implant with natural coral showed 64.9% apposition(P<0.05). 3. In a microscopic examination, mature lamellated bone was found around the immediate implants and control group, while unabsorbed natural coral around the immediate implants with natural coral was found. 4. All immediate implant groups showed the loss of marginal bone in order from implant with natural coral, titanium implant, and HA coated implant. 5. Implant with natural coral that was placed by the type I interface of the Barzilay's classification immediately after teeth extraction showed low percentage of direct bone contact area, low success rate and a lot of marginal bone loss. Above results suggested that the immediate implants are osseointegrated successfully, although slightly marginal bone was loss.

Coral is a member of the class Anthozoa, which cause injury due to stings from their tentacles containing nematocytes or from their sharp-edged calcified outer skeletons. Sting from their nematocytes may cause coral poisoning and cause a rare type of contact dermatitis. A 24-year-old woman, who had been contacted to coral during skin-scuba diving in the Philippines 7 days before, was presented with multiple brownish plaques and patches with small vesicles on the dorsum of the left hand. Herein, we report a case of contact dermatitis to coral by the nematocyst stings of corals.
