A Histological Assessment of the Cell Death Induced by Haloperidol on Prefrontal Cortex International Journal of Morphology
Ghanbari,Ali; Kakebaraei,Seyran; Khazaei,Mozafar.
Neuroleptic drugs such as haloperidol has side effects on extrapyramidal pathways. Tardive Dyskinesia is the most important complication. The most characteristic feature of this Tardive Dyskinesia is involuntary movements of mouth and face. In regard to this problem, the induction of gliosis and cell death in the nervous tissue are considered. In this study, adult Sprague-Dawley rats were used as experimental models. Rats were divided into control and experimental groups. The rats were kept in the animal house under standard conditions during experiments. The control rats were intraperitoneally treated with normal saline for 6 days. The experimental samples were treated for the same time with 2, 5 and 10 mg haloperidol. After the trial period, the rats...

Changes in anatomy and root cell ultrastructure of soybean genotypes under manganese stress Rev. Bras. Ciênc. Solo
Lavres Junior,José; Malavolta,Eurípedes; Nogueira,Neusa de Lima; Moraes,Milton Ferreira; Reis,André Rodrigues; Rossi,Mônica Lanzoni; Cabral,Cleusa Pereira.
The deleterious effects of both Mn deficiency and excess on the development of plants have been evaluated with regard to aspects of shoot anatomy, ultrastructure and biochemistry, focusing mainly on the manifestation of visual symptoms. However, there is little information in the literature on changes in the root system in response to Mn supply. The objective of this study was to evaluate the effects of Mn doses (0.5, 2.0 and 200.0 μmol L-1) in a nutrient solution on the anatomy of leaves and roots of the Glycine max (L.) cultivars Santa Rosa, IAC-15 and IAC-Foscarin 31. Visual deficiency symptoms were first observed in Santa Rosa and IAC-15, which were also the only cultivars where Mn-toxicity symptoms were observed. Only in IAC-15, a high Mn supply led...

Morphological study and taxonomical notes on Eudendriidae (Cnidaria: Hydrozoa: Athecatae/Anthomedusae) Naturalis
Marques, A.C.; Mergner, H.; Höinghaus, R.; Santos, C.M.D.; Vervoort, W..
The morphology of 25 species of the family Eudendriidae was studied, with special regard to their reproductive organs, using techniques of SEM and optical microscopy. Whenever possible a re-analysis of the diagnostic characters of these species was carried out. Furthermore, several synonymies were confirmed or discussed and remarks on taxonomical details are presented. A developmental (ontogenetical) series is proposed for the reproductive differentiation, and its usefulness for phylogenetic analysis is considered.
Tipo: Article / Letter to the editor Palavras-chave: Hydrozoa; Eudendriidae; Eudendrium; Myrionema; Systematics; Morphology; SEM; Optical microscopy; 42.79.
