Quantitative zooplankton samples were collected at nine stations in waters adjacent to Ullung Do and Tok Do Islands in the summer, 1995. Morphology and reproductive biology of a marine cladoceran Evadne spinifera were studied. Gross length of E. spinifera ranged 0.53∼1.14㎜, standard length; 0.20∼0.58㎜ and tail spine length; 0.07∼0.18㎜, respectively. Its fecundity in terms of the number of embryos per batch ranged 1∼7 (mean: 3.1) and sexual individuals were not observed.

김세화,조성택,류재혁 ( Se Wha Kim,Sung Taek Cho,Jae Hyuk Ryu ) 한국하천호수학회 1993 생태와 환경 Vol.26 No.3

Innvestigations on the morphology and reproduction of the freshwater cladoceran Daphnia similis were carried out using materials collected in waters adjacent to Inchon City in June 20, 1992. A total of 163 specimens randomly sorted from the sample was measured for their body length, viz., maximum body length(ML): 0.42-3.57mm, standard length(SL): 0.32-2.12 and body width(BW) : 0.21-1.70. Their means were 2.44, 1.39 and 1.16, respectively. Correlation analysis among three lengths revealed that the body shape of this species might hardely changed with the embryonic development in the brood space. The number of parthenogentic embryo varied from 1-27 per batch. Sexual females were less than 10%. Relationship between the number of embryos per brood and ML showed the saturation curve with the ML limit around 3-3.5mm. Fertility of D. similis was discussed in relation to body length.

Seasonal distribution of zooplankton community in Inchon Dock, an artificially closed marine embayment has been studied. Samples were collected monthly during the period from December 1989 to December 1991 at four stations in the dock and compared with that at a single station in neighbouring waters of the Yellow Sea. Copepods dominated both in and outside of the dock all the year round, except in late autumn and early winter when protozoans outnumbered. dominant species were Oithona davisae, Acartia bifilosa, Paracalanus crassirostris, Noctiluca scintillas and Tintinnopsis tubulosa. A sharp decline in the abundance was observed in summer 1990 in the dock apparently due to oxygen deficiency (anoxic condition). Although no distinct deference in the abundance of zooplankton was observed between populations in and outside of the dock except in summer 1990, waters out of the dock showed to have a prosperity in species number throughout the year. Moreover, four species of copepods, Centropages abdominalis, Pseudodiaptomus marinus, Tortanus forcipatus and T. spinicaudatus occurred solely at the outside of the dock.

Note on the Prey Items of Marine Cladocerans

김세화,윤양호,KIM, SE-WHA,YOON, YANG-HO,ONBE, TAKASHI The Korean Society of Oceanography 1993 韓國海洋學會誌 Vol.28 No.1

Food items of the five species of marine cladocerans were reported to be largely confined to centric diatoms. Reexamination of the prey items, however, revealed that flagellar organisms were also well fed by cladocerans. This additional finding suggests that marine cladocerans might extend their food items to weakly motile flagellates e.g., Prorocentrum micans, Protoperidinium sp. and unidentified flagellates.

김세화,유광일,KIM, SE-WHA,ONBE, TAKASHI,YOO, KWANG IL The Korean Society of Oceanography 1993 韓國海洋學會誌 Vol.28 No.1

Distribution of the marine cladoceran Evadne spinifera in waters adjacent to Korea was studied on the bases of samples collected during the Cooperative Study of the Kuroshio and Adjacent Regions, 1965-1974, and during the Exploitation Research of Marine Resources on the yellow Sea, September October 1992. This species was mainly occurred in August and September in the sea of Japan Distribution in the Yellow Sea was sparse. temperature and salinity ranged $23.42-28.24^{\circ}C$ and $32.11-24.20\textperthousand$, respectively. Maximum abundance of $11{\;}indiv./\textrm{m}^3$ was recorded in coastal waters of Honshu, Japan with $26.80^{\circ}C$ and $32.81\textperthousand$ water. E. spinifera was considered to be a stenothermal animal preferring high temperature.

담수산 (淡水産) 지각류 (枝角類) Moina irassa 의 생물학적 관찰

김세화,유광일,최청일 ( Se Wha Kim,Kwang Il Yoo,Chung Il CHoi ) 한국하천호수학회 1994 생태와 환경 Vol.27 No.3

Preliminary observations on the biology of the freshwater cladoceran Monia irassa were carried out using the samples collected in the vicinity of Inchon City in Jun 20, 1992. A total of 208 specimens randomly sorted from the samples were measured for their body length(BL) and body width(BW). BL ranged 1.07-1.52mm(mean 1.29) and BW, 0.76-1.20(1.03). Embryonic development coincided with the increase of embryo length; stage I: sphere-shaped embryos just after being released from ovary(mean 0.26mm), II: embryos with deviloped embryonic appendages(0.39), III: embryos with well-developed antennae being identified by antennal spines(0.45). No peadogenetic reproduction was observed. Combined effects of embryonic growth and fecundity were positively correlated with BW( I : r^2=0.64, II: 0.42, III: 0.35, mean: 0.45), but not with BL. Fast increase in BW occurred in individuals with early embryos (stage I embryos: X coefficient of EL= 2.09) and expansion rate of brood pouch was gradually decreased with embryonic development (II: 0.67, III: 0.29). The number of embryos per batch ranged 4-25(mean 14.8) and more than 50% animals had 13-17 embryos. Decrease in the fecundity with embryonic development [stage I : 8-22 embryos (mean 16.1), II: 5-25 (15.7), III: 4-24 (14.5)] suggests the presence of prenatal mortality in the species.

A 37 year old male patient was suffered from severe labored breathing caused by post tracheostomy stenosis, which was localized at the mediastinal trachea [cuffed tracheal stenosis] and ranged 1.5 cm in length and approximately 3 ram. in diameter on tracheogram. After dilation of tracheal stenosis with dilator, endotracheal intubation was tried for induction of anesthesia and control of respiration during operation. A tube was placed just beyond the tracheal stenosis without respiratory difficulty. Under the endotracheal anesthesia, circumferential resection of the mediastinal trachea containing the stenosis, approximately 2 cm in length [4 tracheal rings}, was carried out and primary direct end to end anastomosis was performed with interrupted submucosal sutures [3-0 Dexon] and mobilization of trachea Postoperative tracheostomy was not performed. The patient was completely relieved from dyspnea immediately after operation. Post-operative convalescence was entirely uneventful and at present, about 3 months after operation, he is now conducting a usual life. From the literature and our experience, the etiology and treatment of post-tracheostomy stenosis were discussed.

Bleomycin is known as a antibiotic agent for malignant tumors especially sguamous cell carcinoma. We have treated 2 cases of malignant tumors, each one esophageal and lung carcinoma with bleomycin, 630 mg and 510 mg respectively. In case of esophageal carcinoma. the subjective symptoms such as dysphagea and swallowing disturbance are temporally relieved, but the irregular filling defect is not significantly changed in esophagogram. In case of lung carcinoma, the atelectasis of right upper lobe on chest X-ray was slightly regressed in its size without effective improvement of subjective symptoms. However, following additional radioactive $^60{Co}$ irradiation therapy (5200r), marked regression of tumor density and aeration of right upper lobe was observed. But 2 weeks later of ceasatioil of irradiatio:J, atelectasis of right upper lobe was again developed. Fever, anorexia, headache and eruption were developed during the treatmeat with bleomycin in both cases but the sign or symptoms of hone marrow depression, renal or liver damage were not noted.

유광일,남현우,김세화 ( Kwang Il Yoo,Hyun Woo Nam,Se Wha Kim ) 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.1

To investigate the pesticide effect of a frsh-water cladoceran Moina irrasa, experiments were conducted in three mesocosms with three different pestide concentrations (control, 0.001 ㎖ ℓ^-1, 0.005 ㎖ ℓ^-1) in waters of a rice field in the vicinity of Inchon City (126°43`E, 37°6`N). Water temperature ranged 15.7 to 28.4℃, and pH varied from 7.22 to 8.32 in the control, respectively. Population density of M. irrassa at control ranged from 542 to 2,584 indiv. ℓ^-1. At 0.001㎖ ℓ^-1 and 0.003㎖ ℓ^-1 of pesticide, population density of M. irrassa ranged from 214 to 1,123 and 130 to 1,154indiv. ℓ^-1, respectively. After 4 hours from the experiment, the population density of M. irrasa declined intensively at pesticide treatments, and no individuals were found after 16 hours of the experiment at 0.001 ㎖ ℓ^-1 and after 12 hours at 0.003 ㎖ ℓ^-1. Mean fecundity represented by mean clutch size in terms of the number of embryos per batch at each individual varied between 9.8-17.84 at control, and 12.67-16.48, 15.87-16.64 at 0.001 ㎖ ℓ^-1 and 0.003 ㎖ ℓ^-1, respectively. There were found the individuals only with over 12 embryos at 0.001 ㎖ ℓ^-1 and 0.003 ㎖ ℓ^-1.

Nesidioblastosis is a term used to describe pathologic overgrowth of pancreatic islet cells. It also means maldistribution of islet cells within the ductules of exocrine pancreas. Generally, nesidioblastosis occurs in beta-cell and causes neonatal hyperinsulinemic hypoglycemia or adult noninsulinoma pancreatogenous hypoglycemia syndrome. Alpha-cell nesidioblastosis and hyperplasia is an extremely rare disorder. It often accompanies glucagon-producing marco- and mircoadenoma without typical glucagonoma syndrome. A 35-year-old female was referred to our hospital with recurrent acute pancreatitis. On radiologic studies, 1.5 cm sized mass was noted in pancreas tail. Cytological evaluation with EUS-fine-needle aspiration suggested serous cystadenoma. She received distal pancreatectomy. The histologic examination revealed a 1.7 cm sized neuroendocrine tumor positive for immunohistochemical staining with glucagon antibody. Multiple glucagon-producing micro endocrine cell tumors were scattered next to the main tumor. Additionally, diffuse hyperplasia of pancreatic islets and ectopic proliferation of islet cells in centroacinar area, findings compatible to nesidioblastosis, were seen. These hyperplasia and almost all nesidioblastic cells were positive for glucagon immunochemistry. Even though serum glucagon level still remained higher than the reference value, she has been followed-up without any evidence of recurrence or hormone related symptoms. Herein, we report a case of alpha-cell nesidioblastosis and hyperplasia combined with glucagon-producing neuroendocrine tumor with literature review.
