{"title":"[Pharmacological study on blood pressure in rats with bone disorders].","authors":"T Shamoto","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>To evaluate the relationship between the elevation of blood pressure and altered bone metabolism, the changes of systolic blood pressure in six experimental models for bone disorders were investigated. Rats used were either parathyroidectomized, ovariectomized, fed with a calcium-deficient diet, fed with a vitamin D-deficient diet, treated with HEBP (1-Hydroxyethylidene-1, 1-bisphosphonate) or treated with streptozotocin. Hypertension developed in 5-week-old male rats fed with a calcium-deficient diet for 2 weeks, which evoked hypocalcemia and nutritional hyperparathyroidism. The blood pressure returned to normal when fed with a normal calcium diet. In parathyroidectomized rats receiving a normal calcium diet, the blood pressure did not rise, though the plasma calcium level decreased to an extent similar to the rats fed with the calcium-deficient diet. These findings seem to indicate that hyperparathyroidism, but not hypocalcemia, was involved in the elevation of blood pressure in rats fed with a calcium-deficient diet. Hypertension was not observed in rats fed with a vitamin D-deficient diet or treated with streptozotocin. These rats showed not only an increase in parathyroid hormone (PTH) but also a decrease in 1,25 (OH)2 D3. These results may suggest that the presence of 1,25 (OH)2D3 as well as the enhanced parathyroid function is necessary for the development of hypertension. The elevated blood pressure was reduced by a calcium antagonist, nifedipine, or by calcium supplementation, but not by an inhibitor of angiotensin-converting enzyme, captopril, or by calcitonin. This may indicate that hypertension due to nutritional hyperparathyroidism responds to the calcium antagonist nifedipine and to calcium supplementation, but does not depend on renin or salt. Furthermore, an acute hypotensive effect by human PTH (1-34) was not observed in the hypertension of calcium-deficient rats, suggesting the difference between acute and chronic effects of PTH. The hypertension developed in the present experiment may be a useful model for pharmacological evaluation of antihypertensive drugs, such as calcium and calcium antagonists.</p>","PeriodicalId":75458,"journal":{"name":"Aichi Gakuin Daigaku Shigakkai shi","volume":"27 4","pages":"989-1005"},"PeriodicalIF":0.0,"publicationDate":"1989-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13679341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The materials used in the present study consisted of plaster casts for 397 people, ages 4-20, collected on Rarotonga, Mangaia and Pukapuka in the Cook Islands. The dental characters observed were 15 traits on the teeth crown. The samples have been divided into five population series on the basis of their native islands: Pukapuka, N-S group (northern-southern island crossbreedings), Rarotonga, Mangaia, and S group (southern islands except Rarotonga and Mangaia). For comparison with other ethnic populations, the samples excluding the Pukapuka are combined into one group to represent full-blood southern-Cook Island Polynesians and named \"Southern Cook\" here. There were no significant sex differences in the incidences of dental traits in the data used in this study, so they were combined for the statistics. A cluster analysis was carried out to compare inter-population affinities on the basis of Smith's Mean Measure of Divergence (MMD) using the frequencies of shovelling, Carabelli's cusp, protostylid, cusp 6, cusp 7, and deflecting wrinkle. The results are briefly summarized as follows: 1. The differences between the Pukapukans and other four groups in the Cook Islands were observed in the case of 11 characters. Within the samples of the four island groups making up Southern Cook, there were no definitive population differences in dental morphology. The cluster analysis based on Smith's MMD values emerged as two main clusters in the Cook Islands: one cluster consisted only of the Pukapukans, and the other consisted of the rest. The latter was divided into two subclusters. 2. The frequencies of shovelling in the Southern Cook (23%) were quite similar at the medium level (S + S.S), to those in other Polynesian groups as well as in the Micronesian groups. The Pukapukans, however, gave a fairly low percentage (10%). 3. The two populations from the Southern Cook and Pukapuka were compared with other Oceanic populations. The incidences of double shovelling were similar to those of the Guamese, but lower than those of the Hawaiians. The Carabelli's cusp, protostylid and cusp 6 showed higher frequencies than those in the Hawaiians and Guamese. On the other hand, the interstitial tubercle showed a lower percentage than those in the Hawaiians and Guamese. As far as the incidence of the deflecting wrinkle are concerned, the Southern Cook, together with the Guamese, were intermediate between the Hawaiians and Pukapukans.(ABSTRACT TRUNCATED AT 400 WORDS)</p>","PeriodicalId":75458,"journal":{"name":"Aichi Gakuin Daigaku Shigakkai shi","volume":"27 4","pages":"855-83"},"PeriodicalIF":0.0,"publicationDate":"1989-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13636343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The date displayed on the X-Y chart recorder on the selected plane were analyzed quantitatively. 1. The paths of the mandible differed between the outward (from the intercuspal position) and the return (backward to the intercuspal position) movements.

In this study, two types of alloy specimens, namely Ag-Pd alloy and Ni-Cr alloy, were prepared by casting. These specimens were given sandblast treatment by 37 microns or 250 microns Al2O3 particle under the following conditions: 3 kg/cm2 for 30 sec, 5 kg/cm2 for 10 sec, 30 sec and 45 sec, and 7 kg/cm2 for 30 sec. Under each condition of sandblast treatment, changes in roughness and wettability of the alloy surface were measured. After this treatment, the alloy surface was Silicoated, and then a light-cured resin was bonded to it. Specimens were stored in air for one week and thermal cycled from 4 to 60 degrees C for 10(4) cycles. The bond strength was measured by compressive shear stress. It was shown that the sandblast treatment caused the surface area to increase in the range of 1.3-1.9 times. Also, the sandblast treatment made the alloy-water contact angle smaller and wettability greater. Maximum bond strengths for Ag-Pd alloy and Ni-Cr alloy, when sandblast treated and stored in the air for one week, were 213.7 kg/cm2 and 198.7 kg/cm2 respectively. On the other hand, bond strengths for Ag-Pd alloy and Ni-Cr alloy after thermal cycling were 129.5 kg/cm2 and 159.9 kg/cm2 respectively.

The results obtained are summarized as follows: 1. The molar size sequence of the seven species. The pattern of sequence in the molars of the Cercopithecidae was divided into six types: (I) M1 less than M2 less than M3 or (M1M2) less than M3, (II) M1 less than (M2M3), (III) M1 less than M3 less than M2, (IV) (M1M2M3), (V) (M3M1) less than M2, and (VI) M3 less than M1 less than M2 or M3 less than (M1M2). 2.

The two species of Cercopithecus showed predominantly the characteristics of types III, IV and V. ii) The molar size sequence individual data revealed that in the mesiodistal crown diameter types I and II were distributed frequently in the Macaca, types IV and V in the Colobus, and type VI in the Cercopithecus. The reduction of the third molar, therefore, seemed to be more pronounced in the Cercopithecus when compared with the other two genus, Macaca and Colobus, because type VI is the type with more size reduction in the third molar. In the case of the buccolingual crown diameters, the most common size sequences were found in types II and III for the Macaca and Colobus. In the Cercopithecus, however, type V exceeded other types in frequence. iii) The results of the reductive indices showed that the second molars in the Colobus were greatly reduced compared to the first, followed by those of the Cercopithecus and Macaca.
