    Variable temperature ^1H NMR of [Pd(PPh_3) (4,7-R_2-phen)_2][BF_4]_2 (R=H, Me and Ph) has been obtained. The NMR spectra of the potentially five-coordinate complex support that at-40℃ the complex with R=Me is stereochemically rigid with an unusual trigonal bipyramidal structure (Tri. Bip) ; above-40℃ it behaves fluxional motion which appears to proceed via transition state of tetragonal pyramid (Tet. Py.) concurrently accompanying an oscillation of the apical phen. The intramolecular dynamic motion of the complex is explained by a coordinationsite exchange of the phen, and its G_273* for the twist motion from Tr. Bipy. To Tet. (that is, site exchange) was estimated approximately as to be 15.0 Kcal/mol for R=Ph and G_273* for R=Me was 13.9Kcal/mol.

    Assays of serum ferritin concentration in adolescent females were performed in respect of red blood cell (RBC), hemoglobin concentration (Hgb), hematocrit (Hct) and transferrin saturation. Anemia (microcytic hypochromic), with low hemoglobin concentration, was exhibited in 4% of the subjects examined. About 24% of the subjects had abnormally low levels of transferrin saturation. Latent iron deficiency, with low serum ferritin concentration, was present in 66% of the subjects ; the mean values of serum ferritin concentration in males was 60±18.6ng/ml, while that in females was 29±9.0ng/ml.

    In order to clarify how St. mutans is established in the oral cavity and transferred to other hosts, dental plaque from 78 pairs of mothers and children was examined. Bio-typing of the isolated St. mutans was performed according to a biochemical test. As a result St. mutans was isolated in 52 mother-and-child pairs(67%); 32 pairs(41%) had the same biotype of St. mutans in both mothers and children.

    This paper reports the latest findings in a series of studies on the frequency and distribution of the main mineral components and ascorbic acid contained in the fruits of Guava cultivated in Kochi prefecture since 1980. The chemical analysis of components in Guava fruits show normal distributions for calcium, phophorus, potassium, magnesium and water, while the distribution for iron, sodium and ascorbic acid were logarithm-normal. The mineral components in Guava fruits are profusely abundant in the core, while ascorbic acid is more abundant in the peel than in the pulp, with the least amount being found in the core. Guava fruits contains a relatively high amount of ascorbic acid. The pink, white and yellow cultivars grown in Kochi Prefecture were found to contain about 250,300 and > 650mg respectively of ascorbic acid per 100g. The ascorbic acid in Guava juice showed high stability under temperature change, and despite heat treatment at 90℃ for 40 minutes, surprisingly about 90% remained.

    Mt. Tsurugi is located at 134°06'E longitude and 35°51' N Iatitide in the east of Shikoku Island. It rises to 1550 m above sea level and is the second highest mountain in the southwestern Japan. Natural vegetation is well preserved on the mountain ; the following vertical vegetational zones are recognized (Morimoto l971) ; 1000-1600 m alt., Fagus crenata-forest ; 1600-1800 m alt., Tsuga sieboldii-forest ; 1800-1900 m alt., Abies veitchii - and Betula ermanii-forests ; higher than 1900 m alt., Sasa-grassland. Limestone is exposed at Ohtsurugi Shrine and at Gyohba on the northern slope, and a fairly large outcrop can be seen at Nishijima, about 1700 m alt. ; small outcrops and many boulders are found in Sasa-grassland around the top of the mountain and on ridges. The present authors investigated the macrolichen flora of an area of about 9 square kilometers above 1400 m. This study is based mainly on the specimens collected by H. Harada. (a) 321-449,531-631,814-1008,1142-1239 ; (b) 2258-2307,3050-3071,4209-4327 ; specimens (a) are deposited in the herbarium of Kochi University (KOCH) and (b) in the herbarium of Hiroshima University (HIRO). We also utilized the specimens collected by I. Yoshimura, supplemened by collections made by the following : the late Mr. T. Inobu whose specimens are now in Tokushima-ken Museum ; Dr. H. Deguchi, Kochi University and Dr. H. Miyawaki, Saga University. We recognize 170 species of macrolichens on as occurring the mountain, belonging to 39 genera and 18 families. These species include the twelve species newly recorded from Shikoku Island : Alectoria lactinea, Anzia colpota, Cetraria gilba, Cetrelia isidiata. Collema coccophyllum, C. latzelii, Leptogium delavayi, Normandina pulchella, Omphalina hudsoniana, Parmelia galbina, Parmeliella nigrocincta and Peltigera horizontalis.
