Thus, I studied Health services supplied by local health centers and the requirements of the inhabitants visiting the health care facilities. The purpose of this study was to provide basic material for the establishment of Health care policy and the development of health care businesses. The target places for this study were 4 health centers; Chungrang-Gu, Nowon-Gu, Eunpyung-Gu, Songpa-Gu, with 509 mothers who were visiting the Centers. The question items of this study concerned a total of 124 health-related services provided by the Health Centers. The data was collected for a total of 92 days; July 1st~September 30th, 1999. 800 questionaries were distributed and 559 answered, 509 were analyzed finally. The collected data were processed using the SAS program to get mean, standard deviation, percentage. Open questions were made to reveal the opinions of mothers using the health care center. The results were as follows : 1. Among the participants of the study, 49.7% were 25~29 years of age, 84.3% were house wives by current occupation, 56.2% were from 4~6 person households. 52.1 were educated at a high school level, and 43.6% were educated at a collage level. 2. The highest percentage(53.6%) of the users were spontaneous in their utilization of health care center. The major reason for using the Health care center is that it is free to 65.8% of those covered and of low cost to 19.3% of those covered. 3. The satisfaction level of those using the health care center appeared to be generally high. The general average value showed up as $3.027{\pm}0.519$. 4. The level of recognition of the value of the heath care center services was high, particularly in the basic item of diagnoses of pregnancy, particularly in the basic item of diagnoses of pregnancy. However, the satisfaction level of health care education In pregnancy is low at 20~40%. In the meantime, the level of recognition in breast- feeding benefits is high at 76.8%. 5. The rate of realizing health care center's service campaign was generally low at 10~20%. 41.3 of the people knew the advertizing material of the health care centers. 32.4% of the people knew the advertizing material of the health care centers. 32.4% of the people knew the campaign of health care center for importance of breast-feeding benefits. 30.1% of the people knew the campaign for testing congenital mechanism disease. In the meantime about 50% was recognised the health care centers campaign for the importance and time of infants vaccination. 6. The need for enhancement of health care center services was shown to be high as $3.266{\pm}0.676$ as an average, chicken pox vaccination being the most highly requested at $3.565{\pm}0.587.$. 7. Among the open questions, the additional service to be provided were as follows ; increase of campaign of health care center services, furnishing advertizing books in public locations, providing shuttle bus service to the health care centers, extension of desire for preventative injections, rest and play areas for the children of the families serviced, consultation rooms, etc.

We explore the question of whether adenosine 5'-triphosphate (ATP) acts as an excitatory neurotransmitter in guinea-pig gastric smooth muscle. In an organ bath system, isometric force of the circular smooth muscle of guinea-pig gastric antrum was measured in the presence of atropine and guanethidine. Under electrical field stimulation (EFS) at high frequencies (＞20 Hz), NO-mediated relaxation during EFS was followed by a strong contraction after the cessation of EFS (a 'rebound-contraction'). Exogenous ATP mimicked the rebound-contraction. A known $P_{2Y}-purinoceptor$ antagonist, reactive blue 2 (RB-2), blocked the rebound-contraction while selective desensitization of $P_{2Y}-purinoceptor$ with ${\alpha},{\beta}-MeATP$ did not affect it. ATP and 2-MeSATP induced smooth muscle contraction, which was effectively blocked by RB-2 and suramin, a nonselective $P_2-purinoceptor$ antagonist. Particularly, in the presence of RB-2, exogenous ATP and 2-MeSATP inhibited spontaneous phasic contractions, suggesting the existence of different populations of purinoceptors. Both the rebound-contraction and the agonist-induced contraction were not inhibited by indomethacin. The rank orders of agonists' potency were 2-MeSATP > ATP ${ge}$ UTP for contraction and ${\alpha},{\beta}-MeATP\;{\ge}\;{\beta},{\gamma}-MeATP$ for inhibition of the phasic contraction, that accord with the commonly accepted rank order of the classical $P_{2Y}-purinoceptor$ subtypes. Electrical activities of smooth muscles were only slightly influenced by ATP and 2-MeSATP, whereas ${\alpha},{\beta}-MeATP$ attenuated slow waves with membrane hyperpolarization. From the above results, it is suggested that ATP acts as an excitatory neurotransmitter, which mediates the rebound-contraction via $P_{2Y}-purinoceptor$ in guinea-pig gastric antrum.
