| histophysiology of the pancreatic islets of rana tigrina, treated with glucagon. | the effect of mammalian crystalline glucagon (0.5 mg and 2.0 mg/kg) on the blood glucose level and pancreatic islets of rana tigrina was studied at different stages after its treatment. this frog is moderately sensitive to glucagon and exhibits hyperglycemia and regressive changes, primarily in the beta- and secondarily in the alpha-cells of the islet tissue. the effectiveness of the hormone depends upon the dose employed. the restricted damage in only a fraction of the alpha-cells indicates tha ... | 1976 | 801307 |
| effect of glucose administration on the blood sugar and pancreatic islets of the frog, rana tigrina. | glucose evoked significant hyperglycemia in the frog, rana tigrina, 0.5 h after the injection and it took a longer time to regain normoglycemia than mammals, thus exhibiting a low glucose tolerance. the islet tissue of injected animals showed degranulation and atrophy of beta-cells only, the alpha-cells remained almost normal. this damage suggests that the beta-cells of this frog are functionally like those of mammals and other vertebrates, and secrete insulin. a single dose of glucose was found ... | 1976 | 785932 |

| microbial community structures and important associations between soil nutrients and the responses of specific taxa to rice-frog cultivation. | rice-frog cultivation is a traditional farming system in china and has been reintroduced as an agricultural practice in china in recent years. the microbial community in paddy rhizospheric soils has attracted much attention because many microorganisms participate in functional processes in soils. in this study, illumina miseq sequencing-based techniques were used to investigate soil microbial communities and functional gene patterns across samples obtained by conventional rice cultivation (cr) a ... | 2019 | 31440215 |
| tiger frog virus orf104r interacts with cellular vdac2 to inhibit cell apoptosis. | ranaviruses belong to the family iridoviridae, and have become a serious threat to both farmed and natural populations of fish and amphibians. previous reports showed that ranaviruses could encode viral bcl-2 family-like proteins (vbcl-2), which play a critical role in the regulation of cell apoptosis. however, the mechanism of ranaviruses vbcl-2 interactions with host protein in mediating apoptosis remains unknown. tiger frog virus (tfv) belonging to the genus ranavirus has been isolated from i ... | 2019 | 31299465 |
| development and characterization of 33 microsatellite loci for the tiger frog hoplobatrachus rugulosus (wiegmann 1834) through transcriptome sequencing. | the tiger frog hoplobatrachus rugulosus (wiegmann 1834) is a large robust dicroglossid frog widely distributed in southern china, malaysia, myanmar, vietnam and thailand. the escaped bred tiger frog introduced from thailand hybridized with chinese native population may have affected the genetic diversity of local chinese tiger frogs. however, previous microsatellite loci of this species do not offer enough information to construct the genetic map. here, we reported 33 new microsatellite loci fro ... | 2018 | 30574879 |
