Objectives: The leather industry is one of the main examples of industries which play an important role in the Indian economy in terms of exports and employment opportunities, while being blamed for environmental pollution. The objective of this study was to find the advances or improvements in the Japanese leather industry which are not found in typical leather industries in developing countries. We examined the Japanese leather industry in this context because Japan is a developed country in which tanning processes have been a traditional business from ancient times, and also the leather industry has played an important role in the process of economic development of Japan.

When predicting volunteer intention, much attention is paid to the volunteer organization environment (VOE). Given that self-efficacy and motivation have emerged as important predictors of volunteer intention, we adopted a combination of ideas of Bandura's social cognitive theory and Ajzen's theory of planned behavior integrating VOE, self-efficacy and motivation to examine their effects on volunteer intention and to determine whether self-efficacy and motivation mediate the relationship between VOE and volunteer intention. The subjects of this study consisted of 198 community health volunteers in Shanghai city, China.

The floating population refers to the large and increasing number of migrants without local household registration status and has become a new demographic phenomenon in China. Most of these migrants move from the rural areas of the central and western parts of China to the eastern and coastal metropolitan areas in pursuit of a better life. The floating population of China was composed of 121 million people in 2000, and this number was expected to increase to 300 million by 2010.

We have demonstrated that an alternative C5a receptor (C5aR) ligand, the homodimer of ribosomal protein S19 (RP S19), contains a unique C-terminus (I(134)-H(145)) that is distinct from the moieties involved in the C5a-C5aR interaction. To examine the role of I(134)-H(145) in the ligand-C5aR interaction, we connected this peptide to the C-terminus of C5a (C5a/RP S19) and found that it endowed the second binding moiety of RP S19 (L(131)DR) with a relatively higher binding affinity to the C5aR on a human mast cell line, HMC-1. In contrast to the C5aR, the second C5aR C5L2 worked as a decoy receptor.

Objective: We conducted a study to develop an assessment sheet for fall prediction in stroke inpatients that is handy and reliable to help ward staff to devise a fall prevention strategy for each inpatient immediately upon admission.

Methods: The study consisted of three steps: (1) developing a data sampling form to record variables related to risk of falls in stroke inpatients and conducting a follow-up survey for stroke inpatients from their admission to discharge by using the form; (2) carrying out analyses of characteristics of the present subjects and selecting variables showing a high hazard ratio (HR) for falls using the Cox regression analysis; (3) developing an assessment sheet for fall prediction involving variables giving the integral coefficient for each variable in accordance with the HR determined in the second step.

Results And Discussion: (1) Subjects of the present survey were 704 inpatients from 17 hospitals including 270 fallers.

Objectives: To clarify the effect of the female hormone estradiol (Est) on heme biosynthesis in lead-poisoned rabbits, parameters indicating lead exposure, such as free erythrocyte protoporphyrin (FEP) level and δ-aminolevulinic acid dehydratase (ALA-D) activity, were determined.

Methods: Twenty-six male Japanese white rabbits (body weight (BW), 3kg) were divided into four groups: I (control), II (Est), III (Pb), IV (Est+Pb). About 3 weeks after castration, Est (3 mg/kg of BW) was injected intramuscularly, and 2 weeks thereafter, lead (1.

Objectives: This study was conducted to investigate possible factors associated with the recent decrease in birth weight in Kumamoto Prefecture between 1979 and 1997.

Methods: Vital statistics on birth between 1979 and 1997 were obtained from the records of the Ministry of Health and Welfare, Japan, on the basis of which, infants were divided into low-birth weight (LBW: <2500 g) group and the normal-birth-weight (> or =2500 g) group, and the proportions of birth and birth weights by gestational age (from 22 to 42 weeks) of both groups between 1979 and 1997 were compared.

Results: For the normal-birth-weight group, the peaks of the proportions of birth and birth weights by gestational age in 1997 shifted to early gestation, compared with the peaks in 1979.

Two kinds of 3-hydroxypyridine-2(1H)-thiones were synthesized. The visible (VIS) spectroscopic analysis indicated that 3-hydroxy-1-methylpyridine-2(1H)-thione (4a) and 3-hydroxy-1-(2-hydroxyethyl)pyridine-2(1H)-thione (4b) formed stable 3:1 Fe(III) complexes. The stability constant of the 4b-Fe(III) complex was estimated from the competitive reaction with EDTA and was found to be 36.

To detect the type of contact dermatitis caused due to the handling ofAlstroemeria wilhelmina, 1% α-methylene-λ-butyrolactone (α-MBL) dissolved in physiological alien and a five-fold diluted saline solution of original extracts of flowers, leaves and stems of the flower were applied to guinea-pigs for extracts were applied to the animals as the challenge treatment in compliance with the guinea-pig maximization test (GMT). As a consequence, not only primary irritant dermatitis was observed, but also delayed type allergic contact dermatitis due toAlstroemeria wilhelmina was observed. α-MBL determined in the extracts using high-performance liquid chromatography (HPLC) was found to be the biochemical material cause of the contact dermatitis.
