In order to determine the contents of lead, cadmium and zinc, the tissues of the crussian carp, Carassius carassius, collected from the middle streams of the Nakdong river were examined. During the dry season from 8 to 15, March, 1987, six loci were selected to sample the fish and river water; five of them were the midstreams of the Nakdong river i.e., the vicinities of the Andong dam, the Nakdong bridge, the Waegwan bridge, Gangjung and Gaepori, the other one was the Kumho river around the Paldal bridge(see Fig.1). The microanalyses of lead and cadmium contents were undertaken by the atomic absorption spectrophotometer(Model IL-551) connected with CTF-IL 655, while that of zinc by the flame method with IL-551 only. The contents of lead and cadmium in water sampled from Gaepori distant from about 30km downward from the junction with the Kumho river were about 1.5 times higher than those from Gangjung distant about 0.5km upward from the junction, and the content of zinc from Gaepori was slightly higher than that from Gangjung. However, the contents of lead and cadmium in water sampled from Gaepori were three fifth of those from the vicinity of Paldal bridge far about 2km upperward from the junction. In the other words, the contents of lead and cadmium in the samples from the vicinity of the Paldal bridge were about 2.5 to 3 times higher than those from the Gangjung and 5 times higher than those from the Andong dam. The contents of the heavy metals in the tissues of Carassius carassius were relatively consistent to those of the aquatic environments were the fish were collected, with higher contents in the tissues of the crussian carp collected from the vicinity of Gaepori and the Paldal bridge which were so much polluted than in those from other loci in upper stream from the junction. And the contents of lead and cadmium in tissues were positively correlated with the age of the fish, however, that zinc was not. The contents of lead in bone of crussian carp from the vicinity of the Paldal bridge in the group of 0-1 year old fish were similar to those of 4-5 years old fish from Gaepori, and higher than those of 3-4 years old fish collected from the upper stream of the junction. It is likely that fishing from Gaepori and the paldal bridge is not recommended, and all the industrial producers have to pay intensive attention to the water pollution due to the sewage disposal.

PURPOSE: The aquaporins (AQPs) are transmembrane water channel proteins. It is well known that AQP2, -3 and -4 contribute to the urinary concentration in collecting duct (CD) and also reported the presence of these three AQPs in the connecting tubule (CNT). Newborn rats are not capable of producing a concentrated urine. Rats develop the ability to concentrate urine after birth. The purpose of this study was to establish the time of the expression and the distribution of AQP2, -3 and -4 in the developing rat kidney. MATERIALS AND METHODS: Sprague-Dawley rats were used in all experiments. Kidneys were obtained from 16, 18 and 20-day-old fetuses and 1, 4, 7, 14 and 21-day-old pups and preserved and processed for immunohistochemical studies using a preembedding immunoperoxidase procedure. AQP2, -3 and -4 immunoreactivity was detected using rabbit polyclonal antibody and donkey anti-rabbit IgG. RESULTS: AQP2, -3 and -4 appeared first in 16-day-old fetuses in the CD and in 18-day-old fetuses in the CNT. Immunoreactivity for AQP2, -3 and -4 was markedly increased after birth and gradually increased during development. In CNT cells and principal cells, AQP2, -3 and -4 were not distinctly demonstrated on the apical, lateral and basal plasma membrane respectively until 21 days after birth. Distinct polarity of these AQPs both in CNTcells and principal cells were observed at 21 days after birth. CONCLUSIONS: AQP2 -3, and -4 were expressed not only in CD but also in CNT before developing of urine concentrating ability during development and it is concluded that their expression and distribution in CNT may play a role in the development of urine concentration abilities in rat kidney.

BACKGROUND: The concentration of the blood including ACTH, catecholamine, serum prolactine, cortisol is increased due to responding on stress by carrying out endotracheal intubation upon the mutiple trauma patients who were taken to the emergency room. Diazepam is a kind of benzodiazepine pharmacon and common pharmacon used for stability of the patients, relief and pretreatment as a booster for the relaxation of skeletal muscle. This research aims to know how effectively medication of diazepam before endotracheal intubation helps to constrain the reaction on the part of cardiovascular system due to laryngoscopy and endotracheal intubation, and makes concentration of catecholamine in blood changed. METHODS: The subjects are consisted of the patient asked for endotracheal intubation instantly, suffering from caput trauma (GCS 8.0) among the multiple trauma patient, more than 20-year-old who were taken to the emergency room in Chosun university hospital from October 1, 1995 to September 30, 1996. They were decided into 2 classes, 30 people each class, and one (group I ) was carried out endotracheal intubation without injecting diazepam,0.3 mg/kg, and the other (group II) was done with the endotracheal intubation by injecting diazepam, 0.3mg/kg. Group I and group II were measured blood pressure and heart rate before intubation and at 1, 3, 5, 7 minute after endotracheal intubation, sampled arterial blood from femoral artery, and then compared and analyzed. All of the data were recorded by mean, standard deviation, and percentage and repeated measures ANOVA test was used for the statistical test and the data was regarded as statistically significant when p value is below 0.05. RESULTS: 1) They were no significant differences statistically between 2 groups in the distribution of the age, weight, sex of the patients. 2) The changes in the systolic blood pressure had no statistical significance in the comparison between group I and group II, but diastolic blood pressure and the change of heart rate had statistical significance because p value was shown below 0.05. 3) Norepinephrine of blood was significantly lower in group II than group I. 4) Epinephrine of blood was significantly lower in group II than group I. CONCLUSION: It was shown that medication of diazepam before endotracheal intubation made stability of the patients and it changed significantly the reaction on the part of cardiovascular system from stress caused by laryngoscopy and endotracheal intubation. So it will be a good thing to inject diazepam for pretreatment to bring relief of the patients and cardiovascular stability before endotracheal intubation.

BACKGROUND: For the treatment of generalized vitiligo patients with oral PUVA, we can use two different methods; one is to treat the lesions while the whole body is exposed. Another one is to treat the lesions while only the lesions are exposed. PURPOSE: This study was performed to determine whether lesional and whole body exposure in oral PUVA for generalized vitiligo show any therapeutic differences in effectiveness. METHODS: The vitiligo lesions were distributed over the whole body skin of the subjects and the lesion area was less than 6% of the whole skin area. PUVA was done to the subjects more than 20 times after oral administration of psoralen. The patients were classified into two different groups. One is the lesional exposure group in which the patient exposed only the vitiligo lesion. The other is the whole body exposure group in which the patient exposed almost their whole body. RESULTS: Our results show that there is no statistical difference of the therapeutic effectiveness between the two methods. CONCLUSIONS: We recommend lesional treatment rather than whole body treatment to prevent the oral PUVA side effects.

The results of the treatment upon total 132 cases of ankle and foot fractures treated during the period from January 1969 to August 1978 at the Department of Orthopaedic Surgery, National Medical Center have been analysed and reported in this paper. 1. Sex ratio between male and female was 3.7:1. 68 cases (51.5%) cases out of 132 cases were in the age groups of 2nd and 3rd decades. remarkably higher than any other group. 2. 85 cases out of 132 cases were closed fractures and 47 cases were open fractures, but the incidence of the open fracture in higher in the fractures below the metatarsal bones and multiple fractures. 3. 59 cases out of 132 cases were ankle fractures 34 tarsal bone fractures 14 metatarsal bone fractures, 8 phalangeal bone fractures and 20 multiple fractures Accordingly, the incidence of the ankle fracture is higher than other fractures. 4. Ankle fracture was classified in 4 types according to the fracture mechanism (Lauge-Hansen classification). 20 cases out of 59 cases were pronation-abduction type, 15 cases were pronation-external rotation type, 14 cases were supination adduction type and 9 cases were supination-external rotation type. 15 cases out of 59 cases of the ankle fractures were treated by tension band compression internal fixation. The result of this method was much better than other methods. 5. 25 cases out of 35 cases of calcaneal fracture involved subtalar joint according to Rowe classification. 12 cases out of 25 cases of calcaneal fracture involved subtalar joint were Tongue type-C. In the treatment, no relation between restoration tuber angle or Gissane angle and the incidence of complication was obtained. 6. The incidence of the complication, such as secondary oateoarthritis, non union. malunion, occurred higher in the open and multiple fractures than closed and single fractures.
