An influence of bethanidine (B) onpressor effects of norepinephrine (NE) and tyramine (TR) was investigated in the whole rabbits. B, in a dose 1.0, 3.0 and 5.0 mg/kg, i.v., potentiated significantly the pressor effects of NE and TR. Reserpine and desipramine did not increase the NE effect that had been potentiated by B.B also made little modification of NE effect that had been potentiated by reserpine and desipramine. B increased the NE effect that had been potentiated by tranycypromine and guanethidine. The NE pressor effect potentiated by B was decreased by tranylcypromine, but not influenced by guanethidine. The TR pressor effect potentiated by B was not altered by reserpine and guanethidine, but decreased by desipramine and tranylcypromine. B increased the TR pressor effect that had been potentiated by guanethidine. B, when given after administration of reserpine, tranylcypromine or desipramine, exerted little influence on the TR effect. The mechanism of potentiation of NE and TR pressor effects by B seems to be similar to guanethidine, and the potency of B on the influence of NE and TR effects seems to be greater than guanethidine.

There is a limitation to estimate vitamin $B_{12}$ intake due to the lack of data on vitamin $B_{12}$ content of Korean commercial foods. In this study, vitamin $B_{12}$ content was determined in favorite Korean restaurant foods, convenient or instant foods, fast foods and bakery products through a modified microbioassay using Lactobacillus delbrueckii ATCC 7830. Bulgogi and seafood & green pepper griddle had high vitamin $B_{12}$ content, 3.50 and $2.96{\mu}g$/100 g, respectively. Pork suyook, pork griddle and pollack griddle had 0.48, 0.31 and $0.32{\mu}g$/100 g of vitamin $B_{12}$, respectively. In stew, soft-tofu stew with seafood and doenjang stew with seafood had relatively high vitamin $B_{12}$ content, 1.93 and $1.44{\mu}g$/100 g, respectively. Bibimbap and 4 different types of rice porridge, beef & mushroom, chicken & ginseng, seafood or abalone, had 0.36, 0.08, 0.09, 1.64 and $0.13{\mu}g$/100 g of vitamin $B_{12}$, respectively. One serving of haejanggguk, yookejang, chuotang and galbitang had 5.97, 2.04, 2.63 and $1.91{\mu}g$ of vitamin $B_{12}$, respectively. One serving of samgetang and sulongtang had $2.89{\mu}g$ and $6.64{\mu}g$ of vitamin $B_{12}$. In noodles, one serving of cram noodle soup, bibim-nangmyeon, and mul-nangmyeon had 18.8, 1.21 and $0.38{\mu}g$ of vitamin $B_{12}$, respectively. One regular gimbap and one triangle gimbap contained 1.09-2.53 and $0.54-1.11{\mu}g$ of vitamin $B_{12}$, respectively. One cheese-burger, chicken-burger and bulgogi-burger had 0.76, 0.62 and $0.54{\mu}g$ of vitamin $B_{12}$, respectively. A plain bagel and a waffle contained 0.13 and $0.17{\mu}g$/100 g of vitamin $B_{12}$, respectively. Ready-made tomato sauce or cream sauce for spaghetti in a retort pouch contained only a trace of vitamin $B_{12}$. In conclusion, these results should contribute to improving the present food vitamin $B_{12}$ content database, most of which were cited from foreign data, thereby it could be helpful to estimate the vitamin $B_{12}$ intake of Koreans more accurately than before. It will also provide new information for dietary education related to vitamin $B_{12}$ and health.

The purpose of this study was to find how English vowels /a, e, i, o, u/ affect the production of English labials /p, b, f, v/ by Korean learners of English. Sixty syllables were composed by five vowels and four labials in the syllable types CV, VC, and VCV. The nonsense syllables were produced three times by nine subjects. The major results show that (1) in inter-vocalic position, the subjects had higher scores in producing /v/ composed with /a, e, o/ and /u/, while subjects had lower scores in producing /p/ with /i/ and /o/, (2) in post-vocalic position, the subjects had higher scores in producing /v/ and /f/ with /a, e/, and /o/, while subjects had lower scores in producing /b/ with /e/ and /i/, and (3) in pre-vocalic position, the subjects had higher scores in producing /v/ with /e, o, u/ and /f/ with /u/, while subjects had lower scores in producing /b/ with /e/, /i/ and /u/. The results suggest that on the whole, Korean learners of English have much difficulty in producing /p/ with /i/ in inter-vocalic condition and /b/ with /i, /e/ in pre-vocalic position.

The purpose of this study was to identify the effect of structured patient education on knowledge of Hepatitis B type and behavior about self care in chronic hepatitis B patients, and to fine the strategy to promote their self care behavior. The research design was quasi-experiment research. The study method had been done by investigating the experimental group and control group through the questionnaire on 50 patients who had been out patient medicine department in U university hospital in Ulsan from september 1st 1997 to the end of October, 1997. The analysis of the collected material had been done for the homogeneity test in which general characterics of experimental group and control group had been tested by $x^2-test$ and the homogeneity test of the knowledge of hepatitis B type and self care behavior before by t-test. To test the hypothesis the t-test had been given for the difference of the knowledge of hepatitis B type and self care behavior between the two groups and the correlation between knowledge of hepatitis B type and self care behavior performance had been tested by Pearson's correlation coefficient. The results as follows : 1. The 1st hypothesis 'The experimental group which received the structured education should be higher in the knowledge of hepatitis B type than the control group' was supported(t=-6.25, P=.000). 2. The 2nd hypothesis 'The experimental group which received the structured education whould be higher in the self care behavior performance than the control group' was supported(t=-5.15, P=.000). 3. The 3rd hypothesis 'The higher the knowledge of hepatitis B type in the patient the higher the self care behavior performance degree' was supported(r=.492, P=.001). In conclusion, the patients who received the structured education showed the increase in the degree of knowledge of hepatitis B type and self care behavior performance. so the structured education had been judged the nursing intervention had been prerequisite in increasing knowledge of hepatitis B type and self care behavior performance of the chronic hepatitis B patients.

Vitamin B-6 status parameters of mothers were assessed in relation to th condition of the infant at birth and during the neonatal period. Parameters were assessed at birth and then weekly in 18 mother-infant pairs during the neonatal period ; mothers were supplemented postnatally with 2 or 27 mg PN-HCI/d. Vitamin B-6 inadequacy in the 2mg supplemented group was suggested by the vitamin status parameters. Mothers whose infants had unsatisfactory Apgar scores at 5min after birth(<7) had lower vitamin B-6 status parameters than mothers whose infants were scored satisfactory. Also, infants who scored unsatisfactory at birth and whose mothers were supplemented with the low level of PN had significantly lower vitamin B-6 status parameters at 7 days of age than infants who scored satisfactory. Infants scored unsatisfactory showed some beneficial effects in both vitamin B-6 status and growth associated with the higher level of maternal postnatal vitamin B-6 supplement. In summary, the mother's prenatal and postnatal vitamin B-6 intake were significantly related to the condition of her infant at birth and during the neonatal period, respectively.

Objectives: Recently, angiogenesis has gained an increasing interest as a prognostic factor in breast cancer. In this study we aimed to assess the anti angiogenic effects of HAD, a botanical anticancer remedy which has been prescribed in Daejeon University Oriental Hospital in Korea, on patients with breast carcinoma by measuring the serum vascular endothelial growth factor (VEGF), basic fibroblast growth factor (b-FGF) and platelets levels. Methods: The study included 26 consecutive breast cancer patients (mean age$\pm$standard deviation: 47.5$\pm$8.7 years) with stage II to IV disease who were treated with HAD (mean duration $\pm$ standard deviation: 264.5$\pm$121.6 days). In addition to routine laboratory and staging procedures, serum VEGF, b-FGF levels and platelet counts were determined as antiangiogenic markers. The antiangiogenic effects of HAD were evaluated by analyzing the differences between the values of the antiangiogenic markers before and after the treatment with HAD. Results: Serum b-FGF concentrations were significantly reduced after the treatment with HAD (P=0.042). Serum VEGF concentrations were found to have a somewhat decreasing change, though the change was not statistically significant (P=0.229). Platelet counts had little changes (P=O.80). Conclusions: It is supposed that HAD has effects on decreasing the serum b-FGF levels related with the clinical outcome of breast cancer patients.

In order to designate a present status necessary for establishment of preventive measures and guidelines of health education against hepatitis B in the course of secondary school education, knowledge and practice toward hepatitis B virus infection was surveyed by a questionnare method on total of 4,855 college entrants in the academic year of 1987 and analyzed the data collected using IBM PC(Trigem 88-II) with SAS package program. About two per cent of college entrants had past history of HBV infections not showing any difference between both sexes and geographical regions. About one third(33.7%) of total students had tested hepatitis B surface antigen(HBsAg), only 4% had tested hepatitis B surface antibody(HBsAb) and vaccination rate amounted to 24.6%, one fourth of total subjects. Both serological tests and vaccination were most commonly performed during adolescence, showing higher rates in female students than in male students. The rates also seemed to be higher in those from urban cities than those from rural cities. Students who had acquired correct knowledge that hepatitis B was infected by virus were amounted to 78.5% of college entrants, and remaining 21.5% had misunderstood that rickettsia, bacteria, fungi or parasites were causal agents. Female students were better aware of the causal agents than male students but there was no difference between places of growth. As for mode of transmission of HBV, 51.5% of male students and 47.7% of female students had correct knowledge. A very few student had known that fact that HBV was transmitted by body fluids such as tear(6.9%), nasal discharge(10.1%) and semen or vaginal secretion(19.2%) and majority(75%) of students had misunderstood that hepatitis B virus would be transmitted per os through food ingestion. Approximately one half(48.9%) of college entrants had knew correctly whom to be vaccinated. Approximately one half of the students knew that hepatr;ma(57.8%) and liver cirrhosis(57.4%) might complicate with hepatitis B virus infection, whereas 12.0% of the students responded that bronchitis was one of the complications of hepatitis B infection. In summary of the above results, we highly recommend that health education program for eradication of hepatitis B virus infection should be introduced in curricula of secondary school education in this country.

Purpose: Abdominal cysts of gastrointestinal origin are rare. Their rarity and varied clinical presentations make their pre-operative diagnosis difficult. Methods: Fourteen patients with histological diagnosis of cysts of gastrointestinal origin admitted between 2009 and 2015 were retrospectively analyzed with respect to age, sex, clinical presentation, diagnostic modality, site and type of cyst, management, outcome and follow-up. Results: The mean age at presentation was 4 years and there were six males and eight females. Abdominal pain was the most common presenting symptom. Five patients had an acute presentation-three had distal ileal mesenteric cysts and two had ileal duplication cyst sharing a common wall with ileum. Six patients presented with chronic abdominal pain and lump-three patients had omental cysts and three had mesenteric cysts-two of these in distal ileum and one in sigmoid colon. Two patients presented with antenatally diagnosed palpable abdominal lump. One had a mesenteric cyst of the ileum and the other had a distal ileal duplication cyst which required excision with resection and anastomosis. One patient had an atypical presentation. He was a known case of sickle cell trait and had presented with vague abdominal pain, recurrent cough and multiple episodes of haemoptysis over a period of one year. At laparotomy, gastric duplication cyst was found which was excised completely. Histopathology confirmed the diagnosis. Conclusion: Cysts of gastrointestinal origin are rare and have varied presentation. Surgical excision is the mainstay of treatment. The results and prognosis are good.
