In this study, we investigate the movement disorder from the cortical and cerebellar point of view. Most toxicity studies involving movement disorder has been greatly linked to the motor cortex, thus, we examined neurodegeneration both in the motor cortex and the cerebellar cortex. This study also evaluated the possible role of such degeneration in the etiology of neurodegenerative diseases associated with cassava endemicity. 15 F1 adult Wistar rats were divided into three groups of five animals each. The first group was the control, the second group received 10 mg/kg BW of potassium cyanide (KCN) and the third group received 20 mg/kg BW of KCN for 15 days. The cortical (motor area) and cerebellar tissue were obtained and fixed in formol calcium for cyto-architectural study. In conclusion, toxicity of cyanide in the cortex and cerebellum can involve osmotic imbalance and excitotoxicity at the 10 mg/kg causing increased in cell size and a slower form of degeneration and reactive oxygen species (ROS) generation and lipid peroxidation causing release hydrolytic enzymes from lysosomes that destroys the components of the cytoplasm as observed in the 20 mg/Kg treatment. \u0000 \u0000 \u0000 \u0000 Key words: Neuron, cell death, cerebellum, cortex, movement, degeneration, oxidative stress.","PeriodicalId":15216,"journal":{"name":"Journal of Cell and Animal Biology","volume":"5 1","pages":"31-36"},"PeriodicalIF":0.0,"publicationDate":"2013-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79927148","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}

Twenty crossbred rams (Arkhar-Merino × Moghani and Arkhar-Merino × Ghezel) were randomly allocated into two equal groups. The experimental group received 7.5 mg IM of Estroplan (PGF2α analogue) and the control group received 1 ml of water soluble. A total number of eighteen ejaculates per ram were collected by artificial vagina twice a week 30 min following IM administration. Semen ejaculates were evaluated for volume, sperm concentration, total sperm output, mass and individual motility, methylene blue reduction time-test (MBRT), percentage of live sperm and sperm abnormality rates. The results of the current study shows that PGF2α treatment on crossbreed rams improved most semen characteristics including volume, sperm concentration, total sperm output and MBRT in comparison to control group (P < 0.01). However, other semen characteristics show similar values. We concluded that PGF2α actually improved semen output without any negative effect on sperm qualities.","PeriodicalId":15216,"journal":{"name":"Journal of Cell and Animal Biology","volume":"40 1","pages":"16-20"},"PeriodicalIF":0.0,"publicationDate":"2013-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77715668","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 calves were assigned into treatments having 0 (T1), 15 (T2), 30 (T3) and 50% (T4) molasses which replaced wheat bran in concentrate mixture using randomized complete block design into six blocks of four animals. The dry matter (DM) degradability was determined by incubating 3 g of feed samples in fistulated steers fed natural pasture hay ad libitum supplemented with 2 kg of concentrate. The total DM and organic matter (OM) intake for T2 and T3 diets were higher (P< 0.05) than those fed T1 and T4 diets. The stover DM and OM intake for T2 and T3 diets were higher (p<0.05) than for other treatments. The highest (p<0.05) crude protein intake was observed in calves fed T3 diets. Metabolizable energy (ME) intake was higher (P<0.05) for calves fed on T2 and T3 diets, respectively. Calves fed on T2, T3 and T4 diets had higher average daily gain compared to those fed T1 diet.

The effect of genetic group was significant (p 0.05) difference between HF x Bo and HF x HFBo or J x Bo and J x JBo and thus exotic inheritance beyond 50% showed no improvement in first lactation traits.

The breed additive difference for HF or Jersey was positive and significant (p 0.05) for Jersey x Boran crosses except FLDMY and AFL305DMY.

Nicotine is a chemical substance with high level of toxicity. It crosses through the placenta and accumulates in the developing organs of fetus. Previous investigation indicated that maternal nicotine exposures induce decreased fibronectin expression in lung parenchyma. In this study, the effect of maternal nicotine exposure on laminin expression of the newborn mice lungs has been evaluated. 24 female pregnant Balb/C mice were divided randomly into four groups as follows: Experimental Group 1 (Exp D1); received 3 mg/kg nicotine intra peritoneal injection (IP) from gestational day 7 (GD7) to the last day of pregnancy, Experimental Group 2 (Exp D14); received 3 mg/kg nicotine from GD7 to post natal day 14, Groups 3 and 4; as sham control groups (Sha-Con) received the same volume (3 mg/kg) of normal saline parallel to experimental groups. At the end of exposure times, all the newborns were anesthetized, their lungs were removed and prepared for immunohistochemical method and real-time polymerase chain reaction. Our finding indicated that laminin alpha 5(Lama5) mRNA expression in the lung of newborn in the nicotine treated Exp D1 decreased by 0.63 fold but increased in Exp D14 by 1.57 fold comparing to Sh-Con groups. Lama5 immunoreactivity was not similar in different parts of the lungs including alveoli and bronchiole, having a significant increase in the experimental groups in contrast to the Sh-Con groups. These data also indicate that maternal nicotine exposure may induce abnormal laminin expression which may cause defects in lung function during life time.","PeriodicalId":15216,"journal":{"name":"Journal of Cell and Animal Biology","volume":"34 1","pages":"226-232"},"PeriodicalIF":0.0,"publicationDate":"2012-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73959517","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}
