담수산 석패와 7종의 발생시기에 관한 연구

박갑만,권오길 한국패류학회 1995 The Korean Journal of Malacology Vol.11 No.2

The unionid family Unionidae contains several genera in Korea, among which occru considerable variations in life histories and sexual conditions. Seven species from the Korea(Anodonta arcaeformis flavotincta, A. woodiana, Unio douglaseae, U. douglasiae sinuolatus, Lamprotula gottschei, Lanceolaria acrorhyncha, Solenaia triangularis)were stueide in order to identify and describe the seasonal gonadal activity and the visceral sex. The gonads of seven species were histologically examined by using the paraffin block technique for sectioning. All seven species were uniformly dioecious and testicular activity in six species except one species, S. triangularis, generated sperm-morulae(multinucleated cell). The annual reproductive cycle of the seven species could be classified into five successive stages; multicative, growing, mature, spent, deginerative and resting stages. The breeding season of six species was the summer and that of A. a. flavotincta was the winter.

한국산 양서·파충류의 질병매개 기생충 현황: 기후변화에서 병원체 전파에 미치는 영향에 대한 고찰

박갑만 한국자연보호학회 2012 한국자연보호학회지 Vol.6 No.2

To determine the status of Korean wild reptiles and amphibians infection and relation with climate change of Korean peninsula, references were reviewed. Wild animals serve as intermediate, reservoirs and paratenic hosts to zoonotic parasites of human beings. The parasites and disease can be a serious problem for all herptiles. The infectious diseases, in particular, become parasitized through contact with other reptiles or contaminated objects and environments, or by eating infected food items. Worms are one of the most common intestinal parasites. Among reptiles, the most common infections are flatworms (trematodes), roundworms (nematodes), tapeworms (cestodes), and spiny-headed worms (acanthocephalans). A total of 20 species for infectious diseases from Korean wild reptiles and amphibians has been reviewed. Among them, 11 species was amphibians and 9 species for reptiles. The Korean wild herptiles had total 41 kinds of parasite pathogenic organisms. Meximum infections belonged to Rana nigromaculata as amphibians had 22 kinds of parasite organisms, including Gorgodera aponica, Gorgodera bombinae, Diplodiscus japonicus, Haematoloechus sibiricus japonicus, Pleurogenoides japonicus, Haematoloechus nanchangensis, Haematoloechus variegatus, Haematoloechus lobatus koreanus, Neodiplostomum seoulense, Halipergus japonicus, Haematolechus japonicus, Loxogenes liberum, Baerttia japonica, Ophiotaenia manae, Oswardcruzia lualata, Icosiella kobayashi, Pharyngodon pobypedates, Gyrinicola japonica, Catadiseus sp., Ophisthodiseus sp., Diplorchis sp., and Sparganum. Also, Dinodon rufozonatum as reptiles had 5 kinds of parasite, including Cotylaspis coreensis, Cotylaspis sinensis, Cephalogonimus japonicus, Astiotrema reniferum, Astiotrema odheri, Kaurma orientalis, and Astiotrema sp.. In the future, under the climatic extremes on Korean peninsula such as floods, drought and temperature variability, in particular, the susceptibility of amphibian and reptiles to infection will be increased and they have implications for the emergence of disease and the potential for climate change to exacerbate amphibian decline.

Anodonta arcaeformis와 Cristaria plicata 유생의 미세구조적 연구

박갑만 關東大學校 醫科大學 醫科學硏究所 2002 關東醫大學術誌 Vol.6 No.1

Two species of freshwater mussels in Korean, Anodonta araceformis and Cristaria plicata, were compared in regard to the vaious texononmical characteristics of glochildian. The out-demibranchs of all females of species have served as marsupial pouch. The breeding season of these two species was the winter breeder. The glochidia of A. arcaeformis and C. plicata were separated one by with the mucous strings. The shape of the glochidium of A. arcaeformis and C. plicata is apparently sub-triangular and is average size is 250 μm in 240 μ in height and 230×310 μm, respectively. Two glochidial shell valves are of same size, kept together by ligament of 235 μm and 220 μm in width. Each of the glochidial shell valves has studded with many spines on the superior face. a large area at the apex of the valve surrounding the base of the hook is provided with numerous small spines which become progressively smaller towards the periphery of the area. A larval thread of A. arcaeformis and C. plicata, without any accessory structure and 2.6 μm and 2.4 μm in diameter, emerges from a canal located at center of ventral plate of the mantle. The results indicated that the glochidial morphology be reveal characters useful for the classification of different species and for the interrelations between genera.

박갑만 한국자연보호학회 2013 한국자연보호학회지 Vol.7 No.2

The present study was performed reviewing references determine the infection status of Korean freshwater fishes and relation with climate change of Korean peninsula. The most common infections of Korean freshwater fishes are flatworms (trematodes) and spiny-headed worms (acanthocephalans). Total 61 species of Korean freshwater fishes for infectious disease has been reviewed. Among them, 44 species of freshwater fish belong to Cyprinidae and 17 species for Cobitidae, Siluridae, Bagridae, Amblycipitidae, Synbranchidae, Centropomidae, Odontobutidae, Belontiidae, and Channidae. The Korean freshwater fishes had total 35 kinds of parasite pathogenic organisms (Acanthocephala opsariichthydis, Centrocestus sp., Cyathocotyle sp., Diplostomum orientale, Diplostomum sp., Echinochasmus sp., Echinostoma sp., Genarchopsis sp., Holostephanus metorchis, Metacercaria hasegawai, Metagonimus sp., Metorchis taiwanensis, Neoplagioporus zacconis, Palliolisentis chinanensis, Palliolisentis chunjuensis, Prosorhpynchus sp., Centrocestus armatus, Clonorchis sinensis, Holostephanus nipponicus, Metorchis orientalis, Cyathocotyle orientalis, Pseudexorchis major, Exorchis oviformis, Trachelobdella sinensis, Metagonimus miyata, Isoparorchis hypselobagri, Clinostomum complanatum, Centrocestus asadai, Metagonimus yokogawai, Echinostoma cinetorchis, Echinochasmus japonicus, Diplozoon nipponicum, Metagonimus takahashii, Carassotrema koreanum, and Echinostoma hortense). Maximum infections belonged to Pseudorasbora parva as Cyprinidae had 19 kinds of parasite organisms, including Centrocestus armatus, Clinostomum complanatum, Clinostomum complanatum, Clonorchis sinensis, Cyathocotyle orientalis, Echinochasmus japonicus, Exorchis oviformis, Holostephanus metorchis, Holostephanus nipponicus, Metacercaria hasegawai, Metagonimus yokogawai, Metorchis orientalis, Metorchis taiwanensis, Pseudexorchis major, Cyathocotyle sp., Diplostomum sp., Echinochasmus sp., Metagonimus sp. and Prosorhpynchus sp.
