Adverse pregnancy outcome in rats following exposure to a Salacia reticulata (Celastraceae) root extract BJMBR
Ratnasooriya,W.D.; Jayakody,J.R.A.C.; Premakumara,G.A.S..
The root extract of Salacia reticulata Wight (family: Celastraceae) is used in Sri Lanka by traditional practitioners as a herbal therapy for glycemic control even during pregnancy. It is recognized that some clinically used antidiabetic drugs have harmful effects on pregnancy but the effects of the S. reticulata root extract on reproductive outcome is unknown and deserves examination. We determined the effects of the S. reticulata root extract on the reproductive outcome of Wistar rats (250-260 g) when administered orally (10 g/kg) during early (days 1-7) and mid- (days 7-14) pregnancy. The root extract significantly (P<0.05) enhanced post-implantation losses (control vs treatment: early pregnancy, 4.7 ± 2.4 vs 49.3 ± 13%; mid-pregnancy, 4.7 ± 2.4 vs...

Cytogenetic and teratological effects of mancozeb pre natal exposure on rats BABT
Castro,V. L.; Tambasco,A. J.; Paraíba,L. C.; Tambasco,D. D..
Studies were conducted on the dam’s fertility and pup viability, litter physical and motor development and chromosomal analysis with female rats exposed to different concentrations of mancozeb, at initial and organogenesis periods of pregnancy. The exposure did not interfere with the pregnant females or their estrous cycle but resulted in retarded physical development, with exception of the vaginal opening and tests descent; which were in advance. The litter body weight was not affected. The examination of swimming performance indicated an initial impairment and a posterior recovery. The observed chromosome damage in dams and pups was found to enhance with the fungicide’s concentration. The results obtained led to the conclusion that even in the absence of...

Development of the Morphostructure and Meat Value in Chilota Lambs International Journal of Morphology
de la Barra,R; Martínez,M. E; Calderón,C; Morales,R; de la Fuente,L. F.
Chilota sheep are typical of the Chiloé archipelago in southern Chile. The objectives of this study were: 1) To describe the development of the morphostructure of Chilota lambs in their first months of life using some variables that determine lamb meat value (zoometric traits and body weight) and 2) To determine the optimum slaughter age. Measurements were taken from 12 male single-born lambs. Body weight, Withers height; Perimeter of thorax, Chest depth, Shoulder point width and Body length were measured in each animal. The first measurements were taken at 7 days old, and the rest at 37, 67, 97, 127, 157 and 187 days old. The body weight variables and zoometric traits developed allometrically throughout the growth phase. The correlation coefficient...

Myosin Va is developmentally regulated and expressed in the human cerebellum from birth to old age BJMBR
Souza,C.C.R.; Dombroski,T.C.D.; Machado,H.R.; Oliveira,R.S.; Rocha,L.B.; Rodrigues,A.R.A.; Neder,L.; Chimelli,L.; Corrêa,V.M.A.; Larson,R.E.; Martins,A.R..
Myosin Va functions as a processive, actin-based motor molecule highly enriched in the nervous system, which transports and/or tethers organelles, vesicles, and mRNA and protein translation machinery. Mutation of myosin Va leads to Griscelli disease that is associated with severe neurological deficits and a short life span. Despite playing a critical role in development, the expression of myosin Va in the central nervous system throughout the human life span has not been reported. To address this issue, the cerebellar expression of myosin Va from newborns to elderly humans was studied by immunohistochemistry using an affinity-purified anti-myosin Va antibody. Myosin Va was expressed at all ages from the 10th postnatal day to the 98th year of life, in...

Postnatal Development of Testis in Gaddi Goat (Capra hircus) International Journal of Morphology
Archana,P; Katiyar,R. S; Sharma,D. N; Farooqui,M. M; Prakash,Ajay.
A study was conducted on the testicles of 30 male Gaddi goats, divided into 3 groups viz; prepubertal (0 day to 18 months), pubertal (<18 months to &gt;5 yrs) and post- pubertal (&gt;5 yrs) ages. The study revealed that the testis was covered by fibroserous tunica albuginia having outer fibrous layer and inner vascular layer with smooth muscle fibers at birth. The tunica albuginia continuously grew in thickness from prepubertal to postpubertal animals. The septula testis arising from the tunica albuginia, divided the parenchyma in lobules and converged at mediastinum testis. Few differentiated and undifferentiated Leydig cells were present in the intertubular spaces of neonates, which enormously increased in pubertal animals and replaced by...

Study of sensory-motor and somatic development of the offspring of rats (Wistar) treated with caffeine BJPS
Silva,Elthon Gomes Fernandes da; Alexandre,Alessandro Aires; Nascimento,Gerlane Karla Bezerra Oliveira; Oliveira,Jaciel Benedito de; Neves,Elizabeth da Silveira; Costa Sobrinho,Austregézilo Vieira da; Silveira,Maria de Fátima Galdino da.
The influence of caffeine, administered to rats, on the somatic and sensory-motor development of the offspring was investigated. Female Wistar rats were divided into a control group and a treated group and received drinking water and a 0.1% solution of caffeine orally, respectively. The offspring, also divided into a control group and a treated group, received daily monitoring until the 20th day of life to verify alterations in somatic neural development. The offspring of the treated group had reduced weight on the day of birth and on the 1st, 5th, 15th and 20th days of life; shorter snout-anus length (evaluation done daily); shorter snout-tail length on the day of birth and on the 1st, 5th and 10th days of life, and signs of retardation of somatic and...

Study of the effects of ß-myrcene on rat fertility and general reproductive performance BJMBR
Paumgartten,F.J.R.; De-Carvalho,R.R.; Souza,C.A.M.; Madi,K.; Chahoud,I..
ß-Myrcene (MYR) is a monoterpene found in the oils of a variety of aromatic plants including lemongrass, verbena, hop, bay, and others. MYR and essential oils containing this terpenoid compound are used in cosmetics, household products, and as flavoring food additives. This study was undertaken to investigate the effects of MYR on fertility and general reproductive performance in the rat. MYR (0, 100, 300 and 500 mg/kg) in peanut oil was given by gavage to male Wistar rats (15 per dose group) for 91 days prior to mating and during the mating period, as well as to females (45 per dose group) continuously for 21 days before mating, during mating and pregnancy, and throughout the period of lactation up to postnatal day 21. On day 21 of pregnancy one-third of...
