Alkaline phosphatase activity was increased in the distal part of the small intestine of pantothenic acid deficient neonatal rats, while acid phosphatase activity was slightly increased and protein concentration was decreased throughout the small intestine. The growth and maturation of the distal part of the small intestine were retarded more severely than in the proximal part.  相似文献

Summary IgE levels in children 5 to 15 years of age were much higher than in their parents. The high IgE levels may result in part from a compensation for low IgA levels in children and in part from intestinal infestations.  相似文献

Summary A reduction in volume and free and total acidity of gastric content was noted along with reduction in ulcer index, with a shift of the site of ulceration from fundus to the glandular part of stomach, following vagotomy in pylorus-ligated rats. Low volume and acidity explains the absence of ulcers in the fundus, but the increased involvement of glandular part in ulceration is possibly due to weakening of the mucosal barrier following vagotomy.  相似文献

Summary Rat endothelial cells in culture can be distinguished from fibroblasts and epithelial cells by their reaction with antisera against human factor VIII (AHF) associated proteins.The data form part of the Ph.D. thesis submitted by A.T. Darnule to the Department of Biology, New York University. Supported in part by NIH USPHS Program Project grant HL15832.  相似文献

The use of anti ACTH (17-39) and alpha-MSH allowed us to detect by immunofluorescence in the Pituitary gland of Grass Snake the site of elaboration of ACTH and alpha-MSH. Corticotropic cells are located in the rostral part of the Pars Distalis and in the Pars intermedia. Melanotropic cells occupy the whole part of the Pars intermedia.  相似文献

Summary For the growing maize roots the increase of the content of wall hydroxyproline was related to a decrease of the root elongation and vice-versa. For the georeactive roots the wall hydroxyproline level was lower in the upper part which elongates more than the lower part containing more wall hydroxyproline.  相似文献

Summary Acid phosphatase activity in the hemolymph and cuticle was higher during the early part of the fifth instar than at any other time. The enzyme activity in the fat body, testes, salivary glands, and midgut was statistically the same throughout the instar.Acknowledgment. This research was supported in part by NSF grant GB 26542-Al to D. F.  相似文献

The relationship between the level of lipid calories in the diet and the effects of oxythioquinox, administered at 200 mg/kg fresh food, for 35 days, was studied on the liver enlargment of rat. The results show that the level lipid calories itself have no effect since, in the treated animals, the liver enlargement is due part to an increase of the water content and part to an increase of the size of the cells.  相似文献

对类似于非线性薄膜一类的非线性偏微分方程提出一种新的算法.该法首先略去非线性部分的影响,或给予非线性部分莱一初值,使非线性部分成为已知,从而将原非线性方程转化为线性方程,并按差分法或其它方法求得其线性解.再将所得线性解代入非线性部分使其成为已知,再次求得其解.这样反复迭代直至收敛,进而求得原非线性方程的非线性解.  相似文献

In Cats with a previous spinal lesion (C 6) saving only a lateral or ventral funiculus, a caudal horseradish peroxidase injection (C 8-Th 1) reveals that some cortical zones (lateral sigmo?d gyrus, medial part of the posterieur sigmo?d gyrus, medial part of the dorsal bank of the cruciate sulcus) send spinal projections, only contralaterally, by way of the dorsolateral funiculus, whereas other cortical zones (anterior sigmo?d gyrus, middle part of the posterior sigmo?d gyrus, lateral parts of the dorsal and ventral bank of the cruciate sulcus) send bilateral spinal projections by way of the ventral and dorsolateral funiculi.  相似文献

Equivalent spaces of 42K were measured in fragments of the submandibular gland of 1-, 7-, 14- and 21-day-old and adult rats in the absence and presence of carbachol and the transport inhibitors ouabain and furosemide. The results indicate that the 42K space was increased by carbachol in an ouabain-sensitive manner at all ages studied and that part of the secretagogue-stimulated K uptake occurred by way of a furosemide-sensitive transport system in the latter part of the postnatal period and in the adult.  相似文献

Summary Immune reactivity of patients with early or advanced breast cancer, compared with healthy controls, has been measured using in vivo and in vitro tests. The results of our study show that impairment of cellular responsiveness occurred in women with advanced disease.This work was supported in part by the CNR, Italy-USA Contract No. 7801062.65, and in part by the Region of Umbria, Italy. Acknowledgment. We wish to thank Mr Mario Andrielli for his expert technical assistance.  相似文献
