The effects of alpha and beta-adrenergic stimulation on triacylglycerol secretion were investigated in isolated rat hepatocytes. Epinephrine within 3h of incubation suppressed triacylglycerol secretion by 35% and increased its cellular content by 18%. The inhibitory effect of epinephrine was abolished by inclusion of phentolamine and also prazosin but not with propranolol. Trifluoperazine c...

the aim of this study was to examine whether the secreted fluid from the uterus influences the survival and fertilization capacity of fowl sperm in the hen oviduct. hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the transfer of sperm into the uterus. twenty-four hours after  artificial insemination, 3 hens with regular...

background: opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract.  heroin is one of the opioid derivatives that abuse increasingly today.  so far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion.   objective:  to define the effect of the acute heroin consumption on basal and vagal-sti...

it is well known that several plant extracts have a lactogenic effect. this response may be inducedthrough the stimulation of prolactin release from lactotrope cells. a partial purification of the activecompound indicated that it is rich in pectin and β-glucan. these materials stimulate secretion of prolactinfrom hypophyseal fragments. in the present study, the effect of β-glucan on the secreti...

conclusions symptomatic hyponatremia secondary to siadh remains a rare complication of cryptococcal meningitis. case presentation a 67-year-old male with liver transplantation due to hepatitis c (hcv) related liver cirrhosis developed severe hyponatremia four months after liver transplantation, which was discovered during routine clinic visit. patient was referred to the emergency department, t...

paraneoplastic syndromes result from secretion of hormones, peptides or cytokines by tumor or immune cross-reactivity between malignant and normal tissues. these conditions are rare in children, but when the clinical presentation of patients with a tumor is unusual, these syndromes should be emphasized . extrarenal tumors with renin-secretion are rare in children. they may be related to paraneo...

Calolisianthus speciosus, an endemic species of cerrado and campos rupestres in Brazil, bears colleters both the leaf base sepal. These (leaf sepal) were anatomically compared to identify differences their structure secretion mechanism. Samples sepals leaves different development stages collected processed according standard methodologies for anatomical ultrastructural studies. Sepal similar, b...

It is well established that the esophageal distention (ED) leads to gastric relaxation, partly by vago-vagal reflex, but till now, the effect of ED on gastric acid secretion has not been investigated. The aim of this study was to investigate the effect of ED on basal and stimulated gastric acid secretion. Methods: Adult male Wistar rats (200-240 g) were deprived of food but not the water 24 h b...
