Daily electrical stimulation of the amygdala in Senegalese baboons (Papio papio) resulted development generalized convulsive seizures focal onset through five distinct clinical stages an average 72 days. The chronologic pattern electroclinical features suggested that vertical intrahemispheric ictal dissemination was primary importance progressive seizure development. Some animals developed spontaneous recurrence both partial complex and seizures. kindling preparation P. papio represents a...

Amygdaloid kindling in rhesus monkeys resulted development of secondarily generalized convulsive seizures an average 196 days. Prior pharmacologic (bemegride) accelerated this seizure one animal. None the animals reached stage 5 primary baboons (Papio papio), even after 400 daily amygdaloid stimulations. Seizure instability, with frequent regression to earlier stage, and difficulty establishing a triggering threshold most monkeys, contrasts our experiences Papio papio. Thus, differences...

SUMMARY: In our earlier study of amygdaloid kindling in Papio papio (Pp), the development partial complex seizure and focal motor was correlated with bifrontal theta discharge increasing Rolandic spike respectively final stage characterized by primary generalized convulsive seizure. Since latter pattern is known to originate from frontal focus man, cortex became suspect pattern. Daily prefrontal stimulation showed that Pp can be kindled this site, culminating a recurrent spontaneous state...

We investigated the relationship between persistence of uterine bacterial infections with cytologically determined endometritis and ovarian function in 65 postpartum Holstein cows. Vaginal mucus discharges were collected, endometrial smear samples (n = 130) collected for cytological bacteriological examinations from cows at weeks 5 7 (pp). Blood 3, pp to determine plasma progesterone concentrations monitor activity. According examination, classified into four groups. The first group 32; 49%)...

SUMMARY This preliminary study utilizing the kindling model of established epilepsy has provided information about most effective routes administration for diphenylhydantoin, phenobarbital, and carbamazepine in baboons cats. The time peak plasma levels these drugs been demonstrated animals so that experimental protocols can be designed to deliver agents at appropriate times prior stimulation. In addition, dose‐effectiveness data is presented species. 1 baboon, phenobarbital was also seen...

SUMMARY Intraperitoneal injections of delta 8‐tetrahy‐drocannabinol (THC) and 9‐THC failed to affect myoclonic response photic stimulation in Senegalese baboons (Papio papio). However. both isomers THC exerted dose‐related antiepileptic effects upon established kindled convulsions provoked by electrical amygdala the same species. Delta was more potent than 8‐THC, terms general toxicity. The appear be due mainly suppression propagation induced afterdischarge distant cérébral structures,...

Contents Seventy pluriparous high‐yielding cows were used to investigate the impact of metabolic traits and body condition score (BCS) during early lactation on subclinical endometritis diagnosed at weeks 5, 6 7 postpartum (pp). Blood samples collected from animals with no peripartum problems second (W2) seventh (W7) pp estimate some blood metabolites including non‐esterified fatty acids (NEFA), β‐hydroxybutyric acid (BHBA), glucose, total cholesterol (T‐chol) urea nitrogen (BUN)....

The current study aimed to define the plasma profile of anti-Müllerian hormone (AMH) and follicle stimulating (FSH) in heifers during postnatal life until achieving puberty, as defined by progesterone (P4) profile, demonstrate a relationship between AMH age puberty onset. Blood samples collected from 11 Japanese Black female calves within 1 week after birth (W 0) then biweekly sixth (WP 6) were assayed for AMH, FSH, P4. classified into two groups based on onset: ≤42 weeks (early group; EP, n...

Endometritis is one of the major diseases causing infertility in cow. Intrauterine infusion povidone-iodine (PVP-I) a common treatment. However, optimal concentration PVP-I for treating endometritis effectively remains unknown. We tested concentrations 2.0% or 0.5% clinical dairy cattle. In Experiment 1, bacteria isolated from uterus were incubated with either PVP-I, and numbers bacterial colonies counted. 2, 18 cows treated (n=9 each group). Cytology samples collected using cytobrush on...

A certain level of endometrial bacterial infection and inflammation is involved in bovine uterine involution during the puerperal period. Factors that hamper normal expose environment to pathological conditions, causing different endometritis levels. The lack proper diagnostic tools extends time conception. Efforts have been made elucidate postpartum environment, including flora, changes transient inflammation, pathophysiology endometritis, improve reproductive performance. E. coli...

The calving interval (CI) is an important determinant of reproductive performance in Japanese Black cattle. present study aimed to compare individual fertility traits among farms classified by CI. In total, 49,780 artificial insemination (AI) records for 7327 cows from 2011 2014 were obtained 622 located Miyazaki, Japan. into three groups (referred as farm CI groups) using the lower and upper 25 percentiles thresholds. mean was 403.5 ± 70.9 days. interquartile ranges 49 days short 114 long...

This study aimed to clarify the association between percentage of follicle number by size over antral count (AFC) and subsequent reproductive performance. A total 306 Japanese Black cattle underwent timed artificial insemination (TAI) 41-62 days postpartum; AFC numbers small, medium, large follicles were recorded 10 before TAI. The cross-sectional blood flow areas dominant (DF) on day TAI corpus luteum (CL) six after recorded. ≥ 2 mm was defined as AFC, percentages each small (S-AFC%; 2-2.9...

SUMMARY Acute administration of taurine produced a transient loss susceptibility to photically induced seizures in photosensitive baboons, but failed affect kindled amygdaloid convulsions rats, and cats. In addition, it was totally ineffective changing the course spontaneous status epilepticus These results suggest that taurine‐deficiency model epilepsy applies only certain types seizure‐generating conditions, apparently excluding convulsions. RÉSUMÉ L'administration élévee de diminuait...
