The airborne pollens were investigated by Durhan's pollen trap in Mt. Kwanak from March 1, 1984 to February 28, 1985. The observed airborn pollens were identified 22 families and 49 genera, which were divided into 27 tree pollens. Most airborne pollens were found from late-March to late-September and a few from early-November to late-February, 1985. The first observed pollen of the year was Alnus on March 5 and the last was Artemisia on Decomber 19, 1984. The maximum amount of daily airborne pollens was 823 grains/cm2 on May 16. Peak day and the maximum amount of major airborne pollens were as follows; 166 grains/cm2/day of Alnus pollen on April 4, 38 gr. of Populus on April. 13, 22 gr. of Quercus on May 10, 791 gr. of Pinus on May 26, 139 gr. on May 26 and 104 gr. of Graminae on September 6, 24 gr. of Ambrosia on Sep. 10 and 236 gr. on May 26 and 104 gr. of Graminae on September 6, 24 gr. of Ambrosia airborne pollen for one year was 12,733 grains/cm2 which were composed of 61% tree pollens and 39% herb ones. Decreasing order of pollen counts was Pinus, Alnus, Quercus and Populus in trees, and Graiminae, Artemisia and Ambrosia in herbs. Most of the airborn pollens were deposited in the day-time and a few at night, the maximum at 2∼4p.m.and the mininum at 8∼10 p.m.

Pollens and their preparations that are being sold as a health food in Korea were examined for. morphology and identity. The Iimall packages of sixteen items of the pollen foods were selected and investigated by staining and microscopy. It was shown that all fifteen items except one contained intact pollens which retain their sporoderms. On the basis of their morphological characteristics, they were identified as the pollens of the plants which belong to ten families: Betulaceae, Compositae, Cornaceae, Cgperaceae, Fagaceae, Geraniaceae, Graminae, LeguminoBae, Liliaceae and Pinaceae. Since the sporoderms which can act as a potent allergen to certain persons were not removed, these pollen. foods can not be safe as a food and. may cause systemic allergy. The only preparation that did not show its sporoderm is less likely to cause allergy than the others.

In order to compare species-specific calcium metabolism, we collected 127 species belonging to 40 different families grown on various habitats including saline, limestone, wetland during the 1996 vegetation period, and analyzed their inorganic ion contents. Plants investigated were divided into 5 groups according to their physiological properties: 1) Chenopodiaceae, Aizoaceae, Caryophyllaceae, Portulacaceae and Phytolaccaceae of Centrospermales and Polygonaceae (Polygonales had a little water-soluble $Ca^{2+}$ but contained high contents of insoluble $Ca^{2+}$ particularly as Ca-oxalate (Chenopodiaceae type), 2) Some plant species such as Rosaceae produced oxalate in amounts insufficient to precipitate all incoming $Ca^{2+}$ and thus contained a surplus of dissolved $Ca^{2+}$ (Rosaceae type), 3) The contents of water-soluble $Ca^{2+}$ in plant species of Crassulaceae. Plantaginaceae, Asclepiadaceae, and Zygophyllaceae were equal to or greater than those of K ($K/Ca{\leq}1$; Crassulaceae type), and 4) K/Ca ratios of Compositae were significantly fluctuated depending on species and soil $Ca^{2+}$ level of their habitats (Compositae type). 5) Certain monocots (Gramineae, Cyperaceae, Juncaceae), in contrast to the dicotyledonous plant families mentioned above, showed a very distinct type of calcium metabolism, that is, the K/Ca ratios of 8~10 were maintained indifferently in the species and their habitat types (Graminae type). These results plants within the same taxon have similar physiological aspects as weel as morphological attributes. To understand calcium metabolism of certain plant species, therefore, it is desirable to approach on the basis of physiological concept (calciotroph or calciophobe) rather than the ecological one (calcicole or calcifuge).

Zea mays Linne belonging to Graminae family has been ordinarily made use of foods and fodder. Maydis Stigma, the stigma of maize, has been discarded without any special application with the exception of being applied as diuretic in the sphere of Chinese medicine, moreover, the pharmacological research toward Maydis Stigma as a medical herb has not been regretfully undertaken at all. The authors hereby paid attention to this point of view and made experiment to find out whether the water extract of Maydis Stigma might possess some pharmacological effect on the motility of the isolated rabbit uterus. The experiment was performed making the use of several agents related to the uterine motility such as acetylcholine, pilocarpine, epinephrine, atropine, barium chloride, quinine sulfate and oxytocin. The motility of the isolated rabbit uterus in Tyrode' solution was recorded with the electric kymograph according to Magnus method. The results of the experiment are as follows. 1. The motility of the isolated pregnant and nonpregnant rabbit uterus represents the tendency of gradual contractility in proportion to the concentration of ZW $10^{-4}$, $5{\times}10^{-4}$ and $10^{-3}$. 2. The uterine contractile effect of ZW $10^{-3}$ probably seems to antagonize the effect of epinephrine $10^{-6}$. 3. ZW $10^{-3}$ does not seem to have the significance with barium chloride, quinine sulfate and oxytocin respectively.

In South Korea a Pedo-sedimentary Sequence(PS) indicating the Last Glacial Maximun(LGM) is typified y a brown to dark brown, relatively stiff paleosol layers formed by repetitive freezing and thawing processes which in turn left characteristi glossic textures in soil-solum, polygolnal structures with a flagipans, vertical soil wedges or freezing cracks, and horizontal foliations, As a pre-LGM sedimentary sequences (older than 25Ka), the Old Fluvial Sequence(OFS) overlain by the Slope Sedimentary Sequence(SS) are distributed commonly at the base level higher than 14-15m above present river-bed along the major river basin. After the LGM (ca. 18Ka), the Young Fluvial Sequence(YFS) appears at an altitude ascending order of sedimentary profiles. In this fluvial organic muds of Jangheungri site(Jinju), Sorori site(Cheonwon), and Youngsan estruarine rivermouth(Mokpo) were exemplified in order to interpret their formation ages and environments. As result of $^{14}C$ datings, the formation ages of te organic muds are Boelling to Alleroed (MIS-1). These organic muds were fomed in fluvial backswamp or local pond/bog in response to shifting fluvial system. On the basis of palynological production dominant with Abies/Picea-Betula and Ranunculaceae, Compositae, Cyperaceae, and Graminae, it was interpreted that more boreal to subboreal condition was prevailed rather than temperate like today during the formation of organic muds and soil moisture condition was a repetition of wet and dry condition.
