  • Nine members of Rhodochorton appearing in coastal waters of Korea were investigated diagnostically. Among them, Rh. densum, Rh. magnificum, Rh. robustum and Rh. codicola were identified previously, while Rh. terminale, Rh. sancti-thomae, Rh. daviesii, Rh. hyalosiphoniae, and Rh. rhizoideum were identified and described for the first time in this country.

  • Two Korean species of Centroceras K tzing, Ceramiaceae was investigated taxonomically. C. clavulatum (Ag.) Montagne collected at several sited along the coast of Korea was characterized by regular dischotomous branches with whorl spines at every node, whereas, C. distichum Okamura collected at Soando in the southern coast was by alternate branches with gland cells around nodes. Biogeographic data show that Korea is almost northern limit in distribution of the former species.

  • 최근 호르몬 대치요법으로 갱년기 증상들만 없어질 뿐 아니라 심장질환, 골다공증 등의 예방은 물론이고 젊음의 유지 및 삶의 질이 높아지자 산부인과 의사는 물론이고 정신과 의사들도 갱년기 증상에 대해서 다시 더 많은 관심을 갖게 되었다. 그리하여 저자는 일반 정신과 의사들이 갱년기 증상을 이해하는데 도움을 주기 위하여 갱년기 증상중 정신과와 관련이 있는 열성홍조와 갱년기 우울증을 중심으로 다음과 같은 몇 가지 점을 문헌고찰을 통하여 재검토하였다. 갱년기 및 폐경기의 정의. 갱년기의 생리(난소의 노화, 주간 율동의 변화, 초일주기 율동의 변화, 시신경교차 상부핵의 일주기 율동의 변화), 혈관운동성 홍조(정의와 병태생리, 원인, 진단, 치료), 갱년기 우울증(정의, 원인, 치료) 등을 재고찰하여 보았다.

  • Purpose: This research investigated the degree and predictors of hot flashes and hypogonadism symptoms in patients with prostate cancer receiving hormone replacement therapy. Methods: The subjects were 111 patients with prostate cancer receiving hormone replacement therapy in two university hospitals located in D city. The measurement tools included Hot Flash Diary and AMS (Aging Male's Symptoms rating scales). The data were analyzed using t-test, ANOVA, and binary logistic regression analysis. Results: The percentage of patients who experienced hot flashes among the participants was 14.4%. The predictors for hot flashes were eating irregularly, having coffee frequently and the types of hormone. The average score of hypogonadism symptom was 2.16 out of five-point scale and the highest score of hypogonadism symptom was the sexual symptoms (2.77 out of five-point scale). The predictors for hypogonadism symptom were eating habits and years of having the illness. Conclusion: These findings provide the information that irregularly eating habit was an important factor in hot flashes and hypogonadism symptoms of the participants. Therefore the development of a nutritional education encouraging regular meals is necessary for the given population.

  • Morphology and reproduction of Polysiphonia atlantica Kapraun et J. Norris were studied on the basis of field and laboratory cultured materials collected from the coast of Korea. The plants consisted of prostrate and erect axes with an extremely soft flaccid texture. Axes were ecorticated and had four pericentral cells. The plants except for female gametophytes had few trichoblasts. Branches in the upper portion of the thallus grew to the same level, resulting in a flat-top form. Tetrasporangia were arranged in straight series. Spermatangial branches replaced whole trichoblasts and had a 1-2 celled serile tip. The procarp had a four celled carpogonial branch. After fertilization, the carpogonium contancted the surface of the supporting cell. The formation of the auxiliary cell from the supporting cell was somewhat delayed P. atlantica from Korea was similar to P. subtilissima Montagne in some features. However, the taxonomic differences between the two species were identified in the development of branches and the number of sterile cells at the tip of spermatangial branches.

  • Purpose: The purposes of this study were to explain the phenomena of hot flashes in climacteric women by using Mexameter, Skin Thermometer, Corneometer, and Laser Doppler Perfusion Imager (LDPI) objectively and to identify the interrelation between the subjective and objective measurements of hot flashes by comparing the two as reported in retrospective questionnaires. Methods: The participants were one hundred women (45-60 yr) who were not currently on hormone therapy, and had reached hot flash scores of 10 or higher. Hot flashes were measured in a temperature and humidity controlled room for 7 hr from 10 am to 5 pm. Hot flashes were measured subjectively and recorded via the Hot Flash Diary Report. When participants felt the hot flashes, they were measured objectively by Mexameter, Skin Thermometer, Corneometer, and LDPI. Results: The frequency of hot flashes in participants ranged from 1 to 7 times. When hot flashes occurred in participants, the erythema, skin temperature, skin hydration, and blood perfusion showed statistically significant changes in all measurements. But, the subjective and objective measurements of hot flashes showed only weak correlations. Conclusion: Results indicate a need for future research with subjective and objective measuring instruments chosen depending variations identified for the study.

  • 홍조 Rhodochorton purpureum (Lightf.) Rosenvinge의 생식에 관한 연구를 일본 북해도산 식물을 중심으로 하여 수행하였다. 이 종은 주로 사분포자낭을 형성하지만 단포자낭은 자연상태나 실험실조건에서도 형성하지 않는다. Nemuro산 식물은 포자낭이나 배우자낭을 형성하지 않고 영양생식에 의한 번식을 하고 있다. 자연상태에서 영양생식은 사상체의 일부에 가근이 형성된 후에 그 부분이 떨어져나가 새로운 개체로 된다. Akkeshi와 Oshoro산(I) 식물에서 형성된 사분포자는 사분포자를 형성하는 식물체로 발달한다. 그러나 Muroran과 Oshoro산(II) 식물에서 형성된 사분포자는 배우체로 발달하는데, 이들 배우체는 사분포자낭과 웅성 또는 자성배우자낭을 형성하므로 배우체에 형성되는 사분포자낭은 유사분열에 의해서 형성되었으리라 생각한다.
